Market Sanitary Products pleasantly surprised by the variety. It is easy to buy a new device to replace the failed. Often the cause of failure - a problem with the head parts that can be repaired by hand.
Structure and working principle crane axlebox
Head parts, or in other words, a gate mixer head, is a locking mechanism at by which it is possible not only to cover the feeding and water, but also to regulate its temperature, pressure.

Thus, the device consists of ceramic and brass parts:
- jumper (metal) where there is a mounting thread and a rubber seal;
- choke (nozzle) located in a metal Jumper;
- stem or rotary mechanism, the structure of which depends on the shape of the head gate;
- washers, which records its location at the tap.
Some manufacturers supply their models fat chamber, through which achieves smooth operation, as well as an increase in the term of the mixer.
By forcing on the gate valve, which is arranged in the rotary rod is driven.
Variety of model structures head parts
plumbing modern market offers a wide range of device models. Ordinary man-a layman at first glance it may seem that the details are the same, but this view is mistaken.

Crane axlebox of embodiment vodozapornogo element are classified as follows.
Rubber (worm)
During rotation of the mixer valve to move the actuator, which presses or releases the rubber gasket. She, in turn, opens or closes the faucet valve seat, and with it controls the water supply.
The advantages of this type are:
- an abundance of parts for each type of mixer;
- repair of worn head parts can be effected personally;
- possible to manufacture rubber seals themselves;
- affordable price.
The disadvantages of this type include:
- small service life;
- the need for a large number of valve revolutions;
- It decreases with time running smoothness, and also there is noise or creaking.
Ceramic (disc)
As the name understood that the design used ceramics. However, it produced only discs, which are responsible for supplying or blocking the water.
The advantages include:
- durability;
- relatively small number of revolutions required for opening or closing the mixer;
- smooth running, low noise.
The main disadvantage is the need to consider the application of filters to clean the water, as well as the high cost of ceramic mechanism.
Ball
The device is used based vodozapornogo metal ball charge of the water supply.
Positive aspects of the model:
- long service life;
- speed, low noise when opening and closing the mixer.
Negative sides:
- high sensitivity to water quality;
- unfitness to recovery.
Before repair (replace) head parts, should double-check what kind of axle-box model is installed in the blender. Knowing this information will allow to buy the right part, thereby speeding up the repair work.
typical failure
The mixer should be repaired if:
- He drips with the valve closed;
- liquid seeps out of the valve;
- uneven jet of water - the appearance of "spitting";
- the flywheel is not fixed in the end positions.

Faults vodozapornyh devices occur for the following reasons:
- Wear of the sealing parts. Rings lose their elasticity, as a result, there is depressurized, and then - a leak.
- Accumulation of dirt between the disks, and as a result - a loose abutting plates, followed by the flow of water.
- Abrasion elements between the rod and the housing. The problem occurs very rarely; in this case it is necessary to replace the entire mechanism.
- Abrasion ceramic plates. Breakage occurs due to contaminated water.
- He becomes attached to the casing head parts.
To clarify the cause of the failure is necessary to remove the mixer and make its disassembly.
Necessary and sufficient tool
In order to disassemble the gate head, replace worn parts on hand you need to have the following tools:
- gas or wrench;
- set of screwdrivers;
- pliers;
- knife;
- ring spanners;
- fum feed;
- waterproof grease.

Just pick up the necessary repair parts, as well as to find out the reason why the water drips is possible only after the analysis of the valve.
Removing node vodozapornogo
Dismantling problematic mechanism performed in the following sequence:
- Operate dismantling flywheel gate head by loosening the locking screw, the retaining part.
- By means of gas or wrench is removed mixer apron.
- Oppositely clockwise twisting of the upper part (using movable or wrench).

Then purge threaded portions mixer and perform inspection and fault analysis.
Repair of gate head
As in the worm, and the ceramic valve heads are used several types of gaskets. Sometimes improper use leads to wear and tear, and then the appearance of a leak.
replacement pads
In order to fix the locking mechanism is not necessary to disassemble the faucet, it is sufficient to remove the rubber ring from the seat. After that a new gasket is processed waterproof grease and assemble.

If it so happened that the hand is not the right material from which to cut a new strip, it is possible for a short time to eliminate the leak using a silicone sealant. Problematic item is coated with a thin layer of silicone, provide dry and then put in place again.
Replacement pressure washer
The second gasket or fluoroplastic Caprolon serves to compensate for the gaps between the ceramic plates. When working on a mechanism to systematically turn the load could cause the washer becomes thinner and seeping water.
For replacement of the upper part should be disassembled. It should remove the locking ring to remove the stem and removing a washer. All removed parts clean, lubricate with special grease and collected.

If during the restoration work could not find a suitable washer, you can "build" a worn thickness. To do this, glue or duct tape enclose a plastic washer, which is a short period of time will eliminate fluid leaks.
Removing foreign elements
When the mixer is flowing from the congestion between the plates or discs rust deposits or debris, it is necessary to completely disassemble the head parts. All its elements should be thoroughly cleaned. The plates need to critically examine. In case of deep scratches on their part should be replaced in order to prevent water leakage.
It is not easy to find a new plate, identical damaged. In such circumstances, you can try old polish. For this fit fine silicon carbide or aluminum oxide powder. One of these means is mixed with technical oil. The resulting paste is applied in a thin layer on the glass segment, and then can start the polishing. The paste should be added to achieve the desired effect.
When the damaged areas Sand, plates should be used to each other, rinse again and perform the installation mechanism.
Repair rubber head parts
Worm axlebox occur for many reasons. Basically crane scrolled or flows due to fault rubber gaskets and physical wear. If water seeps between the mixer and head parts, it is necessary to install a new rubber ring. In the case where the flow gave the crane itself, it is necessary to replace the seal cup.
The procedure works as follows:
- produced dismantling and disassembling the mixer (the same as for devices with ceramic plates);
- made cleaning and washing of the details;
- retaining screw is unscrewed and removed problematic gasket;
- It sets cuff, lubricated and assembled.

If you pick up an identical gasket fails, the protruding edge can be neatly trimmed.
Recommendations made and possible difficulties
Adhering to the following simple tips to professionals, everyone is able to recover the mixer.
- If dismantling is difficult to remove become attached head parts, you should treat it with vinegar or citric acid solution, and leave for a couple of hours. The chemical reaction will make the deposits more friable and allow pull mechanism.
- Increase the service life of the mixer is possible with careful handling and installation of water filters.
- If there is no possibility of buying parts, the flow can be temporarily eliminated by using a silicone sealant. On problematic gasket applied superfine silicon layer and the head parts is set. This simple and uncomplicated method is not suitable for continuous operation.
- When assembling the device can not turn ceramic discs, since the parties have a ground to ensure tightness.
- To avoid scratches during disassembly of the mixer with their hands, it can be wrapped with a cloth.
- Purchase mechanism in specialized plumbing stores may cost a bit more expensive, but the quality of the product is much higher.
- When replacing the gasket is necessary to examine the mixer for chips and cracks, the formation of which speaks of the need to replace the entire mechanism.
Thus, to repair the head parts and thereby recover the mixer personally I am quite capable of every subject to the requirements and recommendations described in the this article.
