Modern valve taps and mixers are rather reliable and durable devices, but work in difficult conditions often leads to their faults. The main cause of breakage is the wear of the details of the crane-ink - the main node of household shock fittings. Although this device today can be easily found in the trading network, it is not worth a hurry to spend money. Crane-shot has a simple design, which allows you to repair the mixer on its own.

Crane-letters: Features of devices and typical faults

Crane-buxes is called the most important and responsible node of any valve mixer, due to which it is possible to quickly turn on or overlap the water supply. It is this simple mechanism that allows you to adjust the value of the duct and thereby install the temperature and pressure we need. The basis of the locking device is a rod with sealing elements installed inside the metal housing with the threaded part.

Depending on the size of the threaded part, there are crane-trays with a diameter of 1/2 and 3/8 inches

About damage crane-inks testify the following faults:

• leak from the crane with the valve closed;
• water leak from the flywheel;
• weakening strength of the jet;
• "Rods" and "strikes" when the pressure is turned on;
• lack of valve fixing in extreme positions.

And even if the faucet works fine, but after turning on the pressure of the pipe begin to make noise and rumble - a crane box can also be to blame.

Varieties and design of locking devices

Today, the market of sanitary equipment offers household plumbing reinforcement with crane of two types:

• with a rubber cuff
• from ceramic liners.

To understand what kind of mixer you are dealing with, it is enough to unscrew the flywheel. The taps of the first type involve multiple rotation of the valve, while the second opened in half turns.

Crane-Trices with Rubber Seal

Devices with rubber insert are also called worm due to the presence of a worm pair. Works a node with a rubber seal is very simple. When the flywheel is rotated, the threaded transmission moves a rod with an elastic washer, due to which the valve plate is tightly pressed to the seat mixer installed in the housing - the flow of water stops. When turning the flywheel to the other side between the parts of the valve, the gap appears through which the liquid comes out.

Crane-shot works due to worm gear and elastic sealing cuff

The magnitude of the duct is regulated by the width of the slot between the plate and the saddle. The worm gear is chosen here it is no coincidence - due to it, it is possible to achieve the movement of the rod to the shares of a millimeter, which allows you to very accurately set the required pressure. Crane bucks breakdowns with a rubber washer most often occur due to wear of the elastic seal. The second malfunction most often happens due to excessive efforts applied to the flywheel, and much less often - due to the natural wear of the threaded part. Usually, the worm transmission breakdown happens shortly after the failure of the rubber cuff - in order to overlap the crane, it is necessary to rotate the valve with great zeal.

Advantages of rubber sealing devices at a low price. In addition, the proceeded gasket can be easily replaced if necessary. As for the shortcomings, it is one - sooner or later, but the leakage will happen. It all depends on the density and wear resistance of the rubber, from which the sealing washer is manufactured.

Crane letters with ceramic pair

Today, locking knots with ceramic inserts came to replace the crane-shotguns with rubber gasket. It is thanks to more wear-resistant details such devices are more reliable and durable.

Ceramic crane letters are reliable and durable devices

The design of the ceramic valve ink is based on the body with a fixedly fixed ceramic disk in which there are several holes. The second wear-resistant disk has the same loops and installed on a rotary rod. Having unscrewed the valve to the half turn, combine the holes on both plates and open water. Due to the fact that the discs are tightly pressed to each other, the fluid passes only on the channel intended for this. To adjust or overlapping the stream, turn a little flywheel. At the same time, the holes are combined partially or interconnected.

The advantages of crane-beverages with ceramic details in their durability and convenience, because to turn on the water "on the full" no reuse of the valve is not required. Minus - relatively high cost and sensitivity to the presence of impurities. The last factor forces the installation of water purification filter.

All about repairing ceramic crane-trays for the mixer

The damage to the shut-off mechanisms with ceramic liners happens for several reasons:

1. Damage to sealing elements. Even in the most modern mixer for sealing, rubber and silicone rings are used, which over time wear out or lose elasticity. For this reason, leaks are happening from under the valve or flowing water from the crane.
2. Fitting of garbage particles between ceramic discs. Because of third-party objects of the surface of the work plates, it is loosely adjacent to each other. Water penetrates into the slot, so completely overlapping the tap is not possible. If this trouble is not eliminated on time, then risks and scratches appear on the disks, which further aggravate the state of affairs.
3. Developing in a pair of stock-housing. It happens because of the natural wear and occurs infrequently. This malfunction is disadvantaged, so you have to replace the crane tap assembly.
4. Wear ceramic plates. Such a breakdown rarely happens and occurs most often due to the poor quality of tap water. To restore performance, the crane-inks will need Remkomplekt, which includes wear-resistant discs of the same type and size.

To find out the cause of the fault, the mixer needs to be dismantled and disassembled. But before this it is necessary to prepare the instrument and block the water supply.

Design Crane-Trices with Ceramic Discs

Before getting to work, you should familiarize yourself with the design of the culprit of trouble.

The performance of ceramic crane-inks provides a pair of ceramic plates with holes

An ordinary locking node with ceramic plates is presented in the figure and consists of the following details:

• housing;
• swivel rod with sealing rings;
• bracket or locking ring;
• top (adjusting) ceramic disk;
• lower (input) ceramic disk;
• sealing gasket.

In addition, some models of crane-beverages are supplied with sliding washers, sicochifier and other parts facilitating operation and making the mixer more comfortable. For the manufacture of metal elements Most often a brass is used, which has high corrosion resistance and wear resistance.

What will take in work

To disassemble the valve and replace worn items, you will need:

• keys - gas and adjustable;
• passatia;
• set of screwdriver with flat sting;
• the key is precipitated - the size "on 17".

You may still need a fum-tape, which is used to seal threaded compounds, and consistent water resistant lubricant. As for the items for repair, it is most likely to prepare everything you need to replace it. This can only be done if there is a complete confidence that the repair kit is suitable for such a crane. In most cases, it is possible to determine what is the cause of leakage, it is possible only after the valve is disassembly.

Removing the shut-off mechanism

Removing the faulty node from the mixer is performed in the following order:

1. Remove the flywheel valve. Most often, the locking screw, which this item is held on the rod, is hidden under a plastic decorative plug. To get to it, you need to remove the plug while driving it with a knife. The screw turns completely, after which the flywheel is removed. Sometimes this item is installed with a little tension, so there may be a little effort.

   Flywheel valve letters fastened with a screw hidden behind a plastic plug

2. Using an adjustable or gas key, unscrew the decorative crane lining (apron) that closes the access to the valve. Often, in places of threaded connections, an oxide is formed that prevents disassembly. If the applied force is not enough, then the details can be heated using a construction dryer or to pump the thread by using vinegar.

   The decorative nut is removed with marginal caution, otherwise you can leave scratches on its shiny surface.

   
   

   In order not to damage the decorative apron when turning out, the part should be wrapped with a piece of dense tissue. A similar gasket between the key and the detail will save the shiny nickel-plated surface of the crane from scratches.

3. Having access to the box, it is removed. To do this, use an adjustable key to which the device is unscrewed in the direction opposite to the movement of the clockwise.

   For removing crane-trays use the adjustable key

After dismantling, all the threaded parts of the mixer can be removed with a brush for metal and washed. After that, it is embarrassed and identifying faulty parts. If the device is not possible to repair, then make a decision on the full replacement of the valve. The assembly is carried out in reverse order, with a delicate tightening. It is best to put the crane to the maximum with your hands, and start the key to start a key, unscrewing the water supply faucet. As soon as flowing from the valve stops, the installation is considered completed. At the same time, the gasket is compressed not to the end, so if necessary, it is possible to pull the connection again.

To prevent the formation of scale on the threaded parts, they are protected using a consistent waterproof lubricant. This will make it easy to disassemble the faucet next time.

Vent repair

As in the crane-tapes with sealing cuffs, several types of gasket types are used in devices with ceramic inserts. In most cases, leakage happens precisely because of their wear.

Replacing the gasket in the saddle of the crane

The ring of dense rubber installed on the body of the valve is necessary for sealing crane-trays. Over time, this gasket "sits" or loses elasticity, which leads to leakage. In some cases, loss of tightness is associated with a locking ring holding a gasket. Under the action of moisture, it is destroyed and damages the rubber element. In any case, damaged parts will have to be replaced.

The strip in the crane saddle is used to eliminate the leaks between the crane-buxes and the mixer housing

Disassembling the locking device will not need, just pull it out of the saddle. Before putting a new gasket in place, it should be covered with a thin layer of waterproof lubrication. If there was no suitable sealing element at hand, the sanitary silicone sealant will help temporarily solve the problem. It is applied by a thin layer on the old gasket and give to dry.

After disassembling the mixer, the crane saddle should be carefully examined. The reason for the loss of tightness can serve as cracks or large sinks on the valve body - in this case, the simple replacement of the gasket can not do, they will have to change the mixer assembly.

Replacing the clamping washer

The second gasket, which is made of materials such as fluoroplast, polypropylene or caprolon, compensate for possible gaps between ceramic plates. In the process of operation, the clamping washer is subjected to constant loads that contribute to its wear. As a result, the part is thinned and cannot press the bypass elements with the former force, which leads to the appearance of the gap, and, as a result, leakageing water.

The fluoroplastic washer eliminates the gap between the ceramic plates

To replace the damaged item, the crane must be disassembled. To do this, remove the locking ring, remove the rod out of the case and dismantle the plastic washer and wear-resistant plates. Before assembly, the surface surface is purified and covered with a thin layer of consistency lubrication.

For fixing the rod in the body of the valve, the retaining ring or spring bracket is used

If it was not possible to find a new puck of the same size, then to eliminate the malfunction, the thickness of the old part is increasing. To do this, its surface is placed on its surface or put the gasket cut from transparent plastic packaging.

Removal of foreign particles

Sometimes leaks are caused by the hit between the plates of the extraneous elements, for example, gravy and rust particles. In this case, to restore the performance of the mixer faucet crane is removed and disassembled. After that, it is necessary to clean and thoroughly rinse all the details. Ceramic plates look thoroughly. If the garbage left deep risks on their surface, then it is better to replace the details with new ones, otherwise water can penetrate into the gap between the discs.

Limestone tax and third-party particles contribute to reinforced wear of ceramic plates

If you have nowhere to buy the same ceramic plates, then you can try to polish their surface. To do this, it will take fine-abrasive powder, which is used when ticking the valves of passenger cars or for sharpening the tool. Most often in its capacity use aluminum oxide or silicon carbide with a graininess of no more than 1200. Abrasive is mixed with machine oil and shall be applied to a thin layer on a piece of glass. Grinding is carried out by multiple circular disk movements over the surface, if necessary, adding a cooked paste. After damages are removed, the plates are torn to each other, washed, and, lubricating the waterproof lubricant, are installed in place.

By repairing a crane, it should be borne in mind that ceramic discs are sorted by one side, so it is impossible to turn them during the assembly.

What to do when damaged metal elements

Unrelated defects of the elements of the locking device include:

• wear and breakage of the case or rod crane-trays;
• chips or cracks on the surface of ceramic plates;
• damage to threaded parts.

If, when disassembling and examining the parts of the locking device, the above deficiencies were detected, the crane bundle is not subject to repair - will have to replace the node assembly.

Is it possible to fix the crane with rubber gasket

Leaks in mixers with worm letters happen for several reasons:

• wear of the threaded parts;
• damage to rubber gaskets;
• defects related to mechanical damage.

With excessive wear of the worm gear or the appearance of cracks on the housing and the stem, the locking device is changed completely.

When leakageing water between the body, the crane-trays and the mixer should replace the sealing ring - the works are carried out in full accordance with the algorithm described above. If the crane itself began to flow, then the rubber cuff should be replaced, which serves as a valve seal.

Most often restore performance worm crane Developed by replacing sealing gasket

Replacement procedure Next:

Before assembling the mixer, it will be necessary to change the sealing ring and replenish the lubricant in the worm pair. This will extend the service life of the shut-off reinforcement and push the moment the next service.

Thanks to the versatile hobbies, I write on different topics, but the most beloved - technique, technology and construction. Perhaps because I know many nuances in these areas not only theoretically, as a result of study in technical University and graduate school, but also from the practical side, as I try to do everything with your own hands.

The crane can be considered the main element of any crane, it is this simple design that the water supply is overlap when the valve is rotated. When choosing a specific model, it is necessary to take into account not only geometric dimensions, but also the operating conditions of this device. The proposed material will make it possible to understand what a crane-box, its device and the principle of operation, and will also help when choosing.

Ceramic and rubber crane

Types of crane letters

As for the classification, depending on the design, you can allocate:

• devices with worm bond, when working simply, the rod is put forward and overlaps the passage through which water received. Worm crane-tank - classic, it is from this category most of the old devices.

Note! It is possible to understand this type of ink in the crane by how many turns need to be done before water overlap. In worm models, the rod sinks smoothly, so you need to make some complete revolutions.

• ceramic - from, actually, ceramics are made not all device, but only 2 disks, which are a locking element. The price is slightly higher than that of a worm analogue, but the ceramic discs are very slowly wear out, besides, the crane can be closed almost instantly, the handle is quite 00 °;

• mark there are also balloons. The ball valve-tank differs from the above in the fact that an ordinary metal ball with a pass-through hole is in the role of the locking element. Just as the ceramic variant allows you to quickly overlap the flow of water.

In general, the design of the crane-bugs of different manufacturers remains the same, only separate parts are changed in order to increase durability. For example, some manufacturers arrange a fat chamber between the gliding sealing and ring, it increases the durability of the piston and reduces the rotation of the handle.

And the locking gasket can be simply protected by brass shell - this will allow it without sprinkling it under loads.

Types + Dimensions of the tank-box are especially important when choosing. If the type of this device affects only the durability and ease of use of the crane, then the possibility of installing trance in the socket depends on the landing size.

More information about the device and installation

As for what species of the Cranbux can be considered optimal, there is no universal response, it all depends on the operating conditions and the requirements for the crane. Therefore, it makes sense to consider the design and principle of operation of the previously listed types of devices.

Device and Principle of Worm Cranbucss

The principle of action is that when rotating the flywheel, the rod moves up and down and the rubber locking gasket attached at its end is reliably overlaps the channel in which water entered. It is a locking gasket that can be considered the most "weak link", but it will not be replaced by difficulty, so that the rubber crane can be considered rather reliable.

Metal rod with chopped left thread (it is also a worm screw) is fixed in the rod. The rod itself is available in the form of a hollow hex rod with a head for installing the handle (flywheel). At the end of the worm screw, a shut-off rubber gasket is fixed.

By appearance, the head under the flywheel can be judged by who manufacturer crane-trays. In the models of domestic production, it has a fourfold shape, in foreign - round notches. For example, a tap of 20 slots - guaranteed overseas production.

If you compare it with analogues (ceramic and ball), then it is possible to note that much less longer durability. But such a crane-shot is much less demanding on the quality of water, so if in the water there are small mechanical inclusions, it is suitable exactly such an option.

As for the sizes, the tap of 3 4, 3/8, 1/2 inches is considered the chapter itself. It is such such diameters of the landing part in the overwhelming majority of houses.

Ceramic crane-shot

The key element of such a device is 2 ceramic plates with a perfectly smooth surface. In each of them done through hole same form. The lower plate is fixed, and the upper is connected to the rod and handle. If the crane-tan with a flywheel requires several revolutions to open, then the maximum, which will require a semoculative analogue - rotation by 90ᵒ.

When the crane opens, the holes on the lower and upper disks is combined, when closing - the upper plate is rotated so that the holes overlap.

Note! The only disadvantage of such a design can be considered almost complete unsuitability for repairs. If a ceramic disk comes out of order, you will have to buy a new tone.

Tightness depends on how tightly the plates are alone to the other, therefore the semorial crane-tape should be skipping only clean water, without sand and other solid inclusions. For example, it can be used to supply water after filter.

About sizes and interchangeability Crane-Buks

Pretty often people want to replace constantly leaking worm. In this regard, the question arises - whether the tap will be required entirely or enough simply into place the old crane-inserts insert a new one.

It is necessary to navigate when choosing the diameter of the planting hole, that is, the size of the part of the crane, which is screwed into the mixer, must accurately match the size of the socket. It is clear that, for example, a tap of a 3-8 inch tap is not suitable for a hole of a smaller diameter.

It is also worth paying attention to the device part under the flywheel. In imported devices, the value has a number of notches, and the domestic part is made at all in the form of a four-man. So, if the crane-box of domestic production is changing on a ceramic analogue, then you will also need to replace the flywheel.

As for the length, in this parameter, most crane-beverages do not differ from each other, which only contributes to their interchangeability.

The procedure for performing work when replacing and repairing cranes

When replacing the operation instructions will look like this:

• first you need to stop the flow of water and proceed to dismantling the old device. The first step is the removal of the cap from the flywheel;
• a bolt will be discovered under it, revealing which, you can remove the valve;
• after that, it is possible to unscrew the tone from the landing socket itself;

• after inspection, the thread and destruction of the garbage can be started to. Works are carried out in reverse order - the box itself is screwed at first, then the decorative cap and the valve turns.

Note! When choosing a new crane-ink, it is extremely important to choose the size properly. It is not necessary for the eye to make the choice, as a result, you can get, for example, with a cranebox with a diameter of a 3/8 inches planting part, while the tap of 1 2 inches was needed.

Installation of the flywheel is performed only if it corresponds to the number of slots on the fitting. It is clear that the crane of the shot 18 of the slots and the flywheel with a square cross section of the hole are simply incompatible.

As for repair, in the case of worm devices, it, as a rule, is to replace the locking gasket. In this case, everything you need to do is dismantle with Kranbucks and replace the old gasket on the purchase new one. If you wish, you can even cut it from sufficiently dense and thick rubber.

It is much worse if the bottom of the landing socket is damaged, as a result of this, even with a serviceable gasket, the crane-shot will be slightly led. In this case, it will be necessary to replace the entire crane, as a temporary measure, you can consider the installation of a thicker gasket.

As for Ceramic Cranbux, most likely, only its complete replacement will help when problems with tightness occurs. But sometimes the cause of the leaks lies in the abrasion of the ring, through which it provides a dense clamp of the plates to each other.

In this case, the repair is possible with your own hands, it is enough to just cut the new ring of about the same thickness (in exact compliance with the size there is no need) and place it instead of the old on the rod. On this possibility of repairing ceramic crane-buildings is exhausted.

Summarizing

Crane-shot is simple, but this is no less important mechanism responsible for the normal operation of any crane in the house. The proposed material will allow to obtain an idea of \u200b\u200bthe principle of operation of such devices and determine the choice.

Video in this article can be viewed as a brief guide to self-replacement Crane-trays.

The water supply in the apartment is a rather complicated plumbing system. And the shut-off mechanism in it is a crane-shot. Without it, it is quite difficult to imagine the normal functioning of the entire water supply system in the dwelling. These devices are responsible for adjusting the water supply through the mixer, for switching on and overlapping it from the crane. They have a certain time Services, after which are replaced. These fixtures are different speciesThey differ in size. And solving the question of how to choose them to replace them, all this must be considered.

Types and dimensions of devices

Externally, all crane-letters are very similar to each other, but on the inner device they can be quite different. Constructively allocate two types of these devices:

• worm - they are called even rubber because of the laying inside the mechanism of the gasket from this material, which serves to overlapping the crane saddle to supply water through;
• ceramic - these devices can still be called disk. From the ceramics, only two discs are made in such crane-letters, which have holes for water passage. One drive is fixed, the second is moving. When turning the handle of the crane for water supply, it opens or overlaps the holes on the first disk.

Attention! Ceramic and worm mechanism can in some cases be interchangeable. But this is possible only if they are suitable for the mixer housing in size and thread.

In the market of plumbing devices and devices today you can see a fairly large selection of crane-beverages both domestic and foreign production. They may vary by bandwidth, water temperature and withstand pressure as possible. There are differences in these devices and in size. When buying devices for replacement, it should be borne in mind that they may differ in the number of slots on the surface of the rod under the flywheel - it is 20 or 24. And the sizes of the threads under the installation in the mixer are 1/2 and 3/8 inches.

Rubber crane

Devices with worm mechanism

Rubber or worm devices are equipped with a rod. When turning the handle of the crane, it is extended. As a result, the gasket in the device opens or overlaps the valve seat and, accordingly, the water supply. The gasket itself can be made of various types of rubber. And it depends on how long it will serve. Its wear can be determined by hum in pipes, which appears when the crane is turned on to the water supply.

The main disadvantage of the crane of this type can be called not too much life of this device. Among the advantages that adapts with a worm mechanism are distinguished:

• fairly low cost of these devices;
• prevalence on sale, which allows you to find the desired model without any problems;
• easiness for replacing with your own hands or to repair this device;
• the ability to make a gasket itself from suitable for this rubber.

Ceramic Type Crane

Structurally, they are very simple. In the manufacture of such devices, two types of materials are used - this is brass and ceramics. Ceramic in them only disks or inserts, with which the feed or turning off the water is adjusted. The disadvantages of such type devices include a higher cost compared to craneboxes with a worm mechanism. In addition, they are more sensitive to the quality of water passing through them. Accordingly, if there is impurities of sand and other foreign particles, the device breakdowns are possible. To protect the device from possible breakdowns, it is better to think about the additional installation of a high-quality entering apartment.

Ceramic crane

But despite a certain number of shortcomings inherent in the type of devices, do not forget about the undoubted advantages of ceramic crane-beks. Among such advantages can be allocated:

• silent device work;
• duration of service life;
• the absence of the accompanying effort to open the flow of water and shutdown it.

Choosing a crane for replacement

Virtually any device requires a replacement time. And when buying crane-letters, it is important not to be mistaken with dimensions, otherwise the acquired device may simply not approach the existing mixer, as a result of which its installation will be impossible. Usually pay attention to the acquisition of crane and in the manufacturer of these devices. The quality of the mechanism and the overall life of its operation depends on this.

If, when buying crane-letters, it is difficult to determine the type of device installed in the system, and it is unknown that it is standing in the mixer - a ceramic type device or with a worm mechanism, it is easy to know with the amount of valve turns for opening or turning off the water supply . If a worm-type device is installed, then turns need to be made 3-4, and in ceramic - only half turns.

Device crane

The valves are "under the slot", which is more common in imported devices, or "under the square" is used, mainly for the models of domestic production. Also a faucet and valve (flywheel) may not be one standard. This also needs to pay attention when purchasing. Before making the purchase of a new device, it is recommended to measure the crane and rod in the old in length, as well as determine the type and step of the thread under the mixer body.

Council. If difficulties arise with measurements and definition of the type of device, it is better to take with you to the store as a sample those valve and crane, which stood in the system so that the specialist helps to choose the desired model of the device.

Although the crane-shot and a rather simple, but very important mechanism, which is assigned to the function of adjusting water supply, its inclusion and overlapping. This device is responsible for the work of any crane in the apartment. Therefore, it is necessary to properly select it to the mixer installed in the system.

The company "Santim" sells different kinds Crane bugs for mixers. Here you can buy Calorie and Zerich products small and large wholesale at a bargain price. In the catalog are presented shut-off devices For the cranes of the domestic and imported production of various diameters and design.

Types of crane bugs

Crane-tape is the main element of the shut-off reinforcement of any mixer that is responsible for adjusting water pressure. In modern water supply systems, two main varieties of crane-beverages made of brass are used:

• worm, overlapping water supply with retractable rod;
• disk devices in which two ceramic plates are the shut-off mechanism.

Both shut-off adjustments are interchangeable and unified. Each has its advantages and disadvantages determined by the conditions of operation (the intensity of use and water quality).

The landing diameter (throughout) is distinguished by taps with threads on 1/2 "and 3/8" for imported mixers, and with metric M18 or M22 - for domestic.

There can be a method for fastening the valve flywheel. Slots are used in imported crane-letters, the number of which can be 15, 18, 20 or 24, and in domestic mixers, the head under the square is used with the fixation of the flywheel with a screw.

In addition to the sizes, specifications include:

• bandwidth;
• operating pressure;
• maximum allowable temperature.

Features Worm Crane Bux

The principle of operation worm crane-hooks is based on the movement of the rod when turning the flywheel of the mixer. A rubber sealing gasket placed at its base overlaps the flow of water. The rod has a kind of hollow hexagon with a head on which the flywheel is attached. The rod is fixed with a metal screw with left-sided worm transmission, due to which the crane-shot and received its name. Inside the case, sealing seals are installed, ensuring the tightness of the structure.

Rubber gasket is the most vulnerable place such a crane. Due to constant loads and temperature effects (expansion and compression from hot water) She can sink and fail. Therefore, over time, it is necessary to clamp a crane for overlapping the water, which can lead to a thread breaking. But the replacement of the sealer does not represent difficulties. The gasket is a consumable element and enters the standard repair kit for mixers. To ensure the durability of the rubber ring, a metal shelter can be installed, protecting it from flattening.

The advantage of worm crane bugs is considered to be their smaller water quality compared to ceramic shut-off adjustment devices. The presence in the system of small insoluble particles (sand, rust, etc.) does not affect the performance of the reinforcement, since the elastic rubber gasket provides tight locking of the channel in the mixer even when foreign substances are inserted.

The disadvantage of the crane-bugs of this type is the low speed overlap of the flow of water. For full locking, it is necessary to make 3-4 turns of the flywheel. But at the same time it can serve as an advantage. The high work of the worm shaft allows you to smoothly adjust the water pressure.

Features Ceramic Crane Bux

The design of such crane bugs is much easier than worm. Two ceramic disks with an ideally smooth surface with the same holes protrude as shut-off elements in such a device. Combining the latter opens the course of water. The lower disk is fixedly fixed in the housing, and the top is fixed on the rotary rod, which rotates with the help of the mixer's flywheel.

The sealing gasket (paronitic, polyethylene, rubber or fluoroplastic) is rigidly fixed on the lower ceramic disk of the crane. Since it is not subjected to dynamic loads, it is practically not wears during operation. The sealing of the case is provided with the help of two seals located on the rotary rod.

To lock the water supply channel with ceramic crane-bucks, enough rotation is 90 or 180 ° (depending on the number and location of the holes on the disks). This makes it easy and quickly adjust the pressure, in contrast to the worm device.

Ceramic crane-inks are durable (due to a smaller amount of moving parts), they can be operated up to 10 years. But their design is vulnerable to poor-quality water containing small inclusions of sand, scale or rust. Solid insoluble particles can lead to uneven abrasion or damage to ceramic discs, which gives a disruption of tightness of the crane-bux. Subsequently, they cannot be repaired and only to be replaced. With low water quality in the water supply system, it is recommended that the mandatory installation of rude cleaning filters is recommended.

Ceramic crane-inks during work do not publish any extraneous sounds, which distinguishes them from worm, resonant even with a slight wear of the sealing gasket. Special plastic sicochs can be used to clean the wist of water caused by cavitation of air bubbles. Their form redistributes the flow and neutralizes an unpleasant sound.

No mixer, today, it is impossible to submit any construction object: the cranes are used both in domestic and industrial conditions, offices, government agencies, etc. The sphere of propagation of the mixers is incredibly large. The comfort and duration of the operation of the mixers depend on the quality of the inner element, regulating the flow of water - crane-trays. The malfunction of this device leads to a violation of the correct operation of the mixer. How to choose a crane and replace the mechanism - read below.

What is a crane-shot? The valve head for the mixer or crane - this is the main element that controls the opening and closing of water. Note that it will correctly call the element of the crane-buxue. Options "Grambox", "Grand Bay", "Cranboks" or "Grand box" are incorrect and not used among plumbers and sellers of sanitary components.

To spend high-quality and replace the crane, you need to deal with what kinds of the mechanism exist, from which it consists and how the item works.

So, the standard crane consists of:

• Hull;
• Fitting;
• Turning rod.

The housing is equipped with carvings and gaskets that provide the tightness of the element. Loss of crane-intensity from the mixer controls the quick-consuming washer.

By type of internal locking elements, the valve heads are

• With ceramic moving plates;
• With rubber cuffs (worm);
• With metal balls.

In addition, there is a crane-shot half-turn type, which, most often, is installed after the filter and passes only clean water without sand, rust, etc. Each type of crane-beverages has its own varieties. Therefore, choosing a new device is better, having an old one with you.

The possibility of installing crane-inks to the mixer's socket depends on the seat of the element.

GOST defines such sizes of crane-trays as 1/2 and 3/8 inches. In addition, to choose a crane for a specific mixer, you need to take into account the length of the rod of the element, the number of slots. So for imported mixers, crane letters for 20 and 24 slots are suitable. If you are hard to choose an item, then you can ask for help you can at any plumbing store (or online store, for example, such as Lerua Merlin).

Worm Crane-shot Mixer: Pros and Cons

Crane-box of a worm-type or as it is also called Granbux - this is a detail consisting of a metal rod with a thread, which is fixed in the rod and extends when exposed to the flywheel. At the end of the screw is a rubber gasket, which is pressed against the valve, overlaps access to water.

The advantages of worm-type cranes can be attributed to:

• Low cost;
• The ability to conduct independent repairs;
• The possibility of making pads (which, most often, is the cause of the element breakdown) on their own.

A minus use of such a detail is much more. The main disadvantages of the product include its briefness, availability large number revolutions, decrease in the smoothness of the course with time, noise.

Installation of the shell is a rather labor-intensive process. How to cope and save time and money, learn from our article:

Ceramic Crane Crane: Advantages and Disadvantages

Crane-letters from a working pair from ceramics came to replace the valve mechanisms. Ceramics is the material obtained by firing clay substances with the addition of mineral. It has heat resistance and durability. Therefore, ceramic valve heads are durable and reliable.

Ceramic plates have the same holes. One of the plates is located in the details housing, and the second is on the stock. When turning the crane, the hole is superimposed on each other, giving the water.

You can replace the plates, when they are damaged, it is possible, but, it will have to pick up the working pane for the size of the part. Most often, it is easier to replace the entire detail.

The main advantages of using ceramic valve heads can be attributed:

• Durability;
• A small number of revolutions that is required to open and closes the crane;
• Silent;
• Smooth move.

The disadvantages include the cost of a ceramic product, which exceeds the cost of part with rubber cuffs and the need to install the filter thin cleaning Water for correct operation of the valve head.

Replacing the crane and crane

Sometimes expensive replacement of the mixer can be avoided by replacing the crane. This can be done quickly and without professional help. At the same time, it should be remembered that various crane-inks are not interchangeable. The same can be with the letters from different manufacturers (the domestic buckle will not be able to replace foreign and vice versa). In addition, if the valve head of domestic production will be changed on the imported analogue, then you need to change the flywheel. Therefore, it is better to go for a new element, having an old crane-tap with you.

It is possible to determine which crane boxing is in the mixer you can, making the movement by the flywheel: if the valve performs four turns, then in the crane is the valve head of the worm-type, if ½ turn is the part is ceramic.

By selecting an item, you can proceed to it. Replacement, with this, must be performed with the water supply disconnected.

After this, in order to replace the valve head:

1. Remove the protective cap from the flywheel with a knife or flat screwdriver.
2. Pull out the bolt under the flywheel, and unscrew the valve of the crane.
3. Clear the threads to which the bolt was fixed.
4. Get fittings.
5. To unscrew the key to unscrew the crane.
6. Clean the seat for a new element.

Installing the new valve head and the assembly of the mixer occur in the reverse order.

If it is necessary for the box to be opened up to the other side, then you should unscrew the lock screw and screw it on the reverse side.

At the same time, it is necessary to carefully check that the crane box is not pulled, otherwise the crane in the near time the crane can flow (it also applies to the threaded compounds of the heated towel rail). After installing the new valve head, you need to open water and check whether the crane does not flow.

How to unscrew the crane, if it baked to the housing

Often, the crane in the plumbing of the Soviet sample cannot be removed using the tool. This is due to the fact that over time, the elements rust and oxidize.

If the valve head accumulated to the mixer body, you can try:

1. Pick up the edges of the element by the adjustable key, to break the element and unscrew the crane. The main thing is, to calculate strength: if you make a little more power, you can easily disrupt cutting and break the crane.
2. Use chemicals. Corporate Rust will be able to vinegar, household chemicals to eliminate rust, oxygen-containing means, WD-40. They will need to smear the element and wait a quarter of an hour until the substance works. If necessary, the procedure can be repeated.
3. Use the thermal method. If the crane is not unscrewed, you can try to heat it with a construction hairdryer. You can use an open fire, but then plastic fittings The mixer can deal with the metal - to darken.
4. Drive the valve head. This method should be resorted only if the other themselves did not justify. Since after work in the housing of the mixer will have to make a new thread. To remove an item in this way, it is first necessary to cut off the protruding part of the jumper with a metal with a metal, and then drill the remaining part.

You can use methods both independently and combining each other.

Repair crane

Repair crane-inks may need if the crane began to flow or the mixer drips even in a closed state. You can perform repairs with your own hands. To do this should be stock necessary tool, Determine the type of valve head and the degree of breakage.

In order to independently fix the crane-taps need Remkomplekt, which includes:

• Screwdrivers (flat and cruciform);
• Keys (wrench by 7 mm and at 17);
• Pliers.

Most often, the repair of worm crane-trays is to replace the gasket. For this, the valve head is twisted, and the rubber insert is replaced by a new one.

If you have to open and close the crane you are with some efforts, and the flywheel itself creaks during the revolutions, then it's time to lubricate the valve head.

This will suit the waterproof silicone grease. To lubricate it, it must be removed from the mixer, and unscrew the shut-off valve from the part. In the valve openings you need to fill the lubricant. After repair, the valve head needs to be assembled and set to the previous place.
