Head parts: the right choice and replacement of the "heart" of the mixer

Head parts is crucial internal parts dvuruchkovogo mixer. Thanks to the work of this element are provided with feed, water shut off and pressure regulation. The item has a certain period of service, after which it can be replaced independently. Head parts is of several types, depending on the size and manufacturing material. What to consider when choosing the product and how to perform his replacement, is set out in this article.

What is important for the mixer head parts (GOST 2589-96)

We should immediately understand what the head parts. This element belongs to a class of locking the crane reinforcement. The construction is made of steel or brass and comprises a body which is equipped with a mounting thread and rubber seals, rotary union stem and fixed in the housing.

The composition also includes details of gaskets, thus ensuring a sealing device and quick- washer, fixing the position of the element in the mixer. To ensure smooth operation and to increase resource generation, some models are supplied with fat chamber.

The inner gate element of the head, depending on the movement of the valve or faucet lever changes its position. In the form of execution it may resemble a flat plate, a metal sphere or worm member with rubber seals.

Head parts mounted inside the mixer that is designed for mixing cold and hot flows. The product is used to supply and shut off water, adjusting the required pressure and the required flow temperature. Such vertical head is designed for mixers, which are installed on washbasins, sink, in the shower, bath, bidet system.

Head parts for the mixer must be manufactured from wear-resistant to the effects of water and mechanical impurity material which easily withstands temperature changes and heat transported liquid. It must be free from leakage circuit withstanding pressure up to 1 MPa, and have a fixed bandwidth, determines the channel diameter.

Important!The minimum degree of wear of the mechanism characterized by vertical head whose angle of rotation is 180 degrees.

Head parts for domestic mixer has standard sizes 1/2 and 3/8 inch set GOST. To import apparatus used Slots 20 and 40.

The operating principle of crane axlebox is that when exposed to a flywheel gate that is located in the rotatable rod, begins to move. He begins to rotate around its axis perpendicular or parallel to the water flow. When the shutter provides access to water, adjusts the intensity of its expiry and blocks its movement.

Varieties head parts for different parameters of mixer

To avoid mistakes in the choice of fixtures, you should know what are the head parts. Based on the rod structures, a gate head may be a worm, or a ceramic ball. The first embodiment is also called a rubber as by the translational movement stem rubberised cuff overlaps the tap saddle for supplying water flow through the mixer. Depending on the movement of the worm shaft head parts is inversely threaded or fitted with special guides.

Ceramic head parts are called disc. Working element in them is represented by two metal-ceramic, highly polished plates with static and rotary holes. mixer operation is provided by combining these holes or divorce.

The globular head parts locking mechanism represented polished metal ball which is inside the through-holes engineering. To block the flow of water, is enough to turn the entire valve 1/4 turn. Such roller axle-boxes advantageously equipped with valves on the supply pipes. The mixers ball head parts are not used.

Depending on the size of the landing also distinguish types of crane-Books. head size may be 1/2, 3/8, 3/4, and M18h1. The valve head can also be classified according to the manufacturer, which shows the domestic and imported products, the angle of rotation, which includes semi- and polnooborotnye model.

The shape of the head, by which the tap is fixed to the handwheel, handle or valve, can be square or splined. Products of the latter type differ in the number of protrusions on the rod for mounting on the flywheel plumbing products. Crane axlebox also may vary the working environment temperature, bandwidth and maximum pressure which can withstand.

The apparatus and distinguishing features worm crane axlebox

Worm (rubber) valve heads are equipped with rods that are put forward when the handle is rotated. They create pressure on the screw gear, propelling himself rod with a rubber gasket.

Gasket, which is arranged in the apparatus, opens and closes the tap seat, regulating the water supply. The flow point of overlap is achieved by a tight connection of the valve disc and the special inner saddle. This gasket may be made from any type of rubber, which also affects the period of its service. Such a screw type valve - a gate old type head design.

Important!Worm head parts provides the most accurate pressure regulation, since the rotation of the flywheel rod moves very slowly.

The outer housing part has a thread, which promotes splicing element of the mixer. For convenience, replacing the structure equipped with special niches for a wrench. The inner core may be threaded or fitted with guides for the movable closure type valve.

Important!If the pipes appeared hum while turning the water, it shows the wear pads.

Among the advantages of this type of head parts can be identified low cost that starts from 100 rubles., The prevalence of sale, ease of replacement element that assumes complete overlap of water and the opportunity to make a gasket independently of suitable rubber.

The main disadvantage of this type is considered to be a short period of operation of the device, which is not more than 5 years. The mechanism also exhibits increased sensitivity to the quality of water. Various salts of metal impurities and accelerate wear of the rubber seal.

A distinctive feature of this type of faucet valve is the need of committing several complete rotations of the crane to fully open or close the section. This friction also affects the frequency over the period of wear. As a result, each time the valve will have to tighten more to ensure a complete cessation of the expiry of the water.

Ceramic head parts: design and the characteristics of head

Ceramic head parts for the mixer has been developed as an alternative to the modern rubber gate head, which is superior in its reliability, wear resistance and durability.

The device is characterized by simplicity of design. It is made of ceramic and brass. Such gate head is represented by two ceramic discs, which are made in the same shape openings. One insert is fixed on the rod, and the other is fixed. When changing the rotary disc varies the size of the crane passage section, whereby the flow of water is regulated. The apparatus is set in a mixer with the help of regular gaskets and washers.

Liquid ends solely through channels intended for this, which is achieved thanks to a good density of the ceramics abutment circles. For opening or closing the tap is performed flywheel rotation by half-turn in one or respectively the other way. The result can be completely open, partially combine or cut off the channels. Such small manipulation of valve control device provides high speed, but it suffers from the accuracy of pressure adjustment.

The advantages of this type of gate head is attributed its noiseless operation, long period operation, which is 5-10 years, the lack of effort to enable or disable the flow water. Rotation angle reaches 90-180 degrees.

Among the disadvantages of ceramic heads is possible to allocate a high price head parts, is an average of 300-350 rubles. The mechanism exhibits high sensitivity to the quality of the passing water. If it has a lot of mechanical impurities in the form of particles of sand, clay sediments, rust and other suspensions, it will quickly lead to jamming mechanism, which is especially important for the head parts 1/2». Ceramics also exhibit resistance to chemical compounds. However, when the output of the mixer core failed internal elements unsuitable for repair.

Useful advice!To protect the ceramic head parts from damage and extend the period of its operation at the input to the apartment centralized water supply piping is recommended to install a filter for coarse water purification.

Useful guidelines for choosing the head parts for mixer

Any device after some time needs to be replaced. Before you buy a head parts for the mixer, it is important to consider some aspects. It is necessary to determine the size of seat, type and pitch of the threaded joint, the stem length and configuration, the number of splines, which is characteristic for the import products. The domestic version of the valves are "under the square."

Important!Import and domestic models are not interchangeable, so to replace the head of the Russian analogue of the foreign must be purchased head parts with flywheel attached.

To replace the worn head gate should buy the exact model from the same manufacturer. In case of selecting the modified analogue is required to take into account the full line-marker values ​​and the interaction of the mixer. To eliminate the error, select the head parts should be in a specialty store, having at itself the old part.

We should not forget about the quality of water, which will affect the continuity and duration of operation of the locking element. The cheapest options offer Chinese manufacturers. Cost gate head is in the range 70-800 rubles. Domestic manufacturer produces high quality products ranging in price from 100 to 1500 rubles. The cost of head parts of the European brand will be 450-2100 rubles.

When buying a new faucet for the bathroom or kitchen need to independently verify what it is installed head parts. To do this, scroll through the flywheel. Rubber head parts for shower or sink will need 3-4 trafficking and ceramic enough just half a turn.

How to change the head parts in the mixer: the sequence of actions

Before you change the head parts should prepare the necessary tools and materials. To do this you need an adjustable and pipe wrenches, Phillips and flat screwdrivers, pliers, knife, dense rubber and cloth. This procedure does not cause any difficulties, so it can carry out on their own without the involvement of specialists.

With a screwdriver is required to unscrew the fastening screw. Making light swaying motion, it is necessary to dismantle the valve. Armed with a pair of pliers, unscrew the decorative nut.

Useful advice!When unscrewing the nut element and between a pair of pliers is recommended to lay a piece of tissue or gum that eliminates the likelihood of damage laths.

Then there is the question of how to remove the head parts. Element via tong gets out of the seat by gripping its upper part with special notches. The procedure is carried out counter-clockwise. Then it is necessary to clean the inside of the mixer.

Using a special oil composition should lubricate all threaded connections. On the prepared seat requires using a new key screw head parts, that is clockwise. Before these items need to wrap the threads with several layers of hemp or fum-tape, which will ensure a tighter connection. However hermetic material should not be too much, because in case of increased pressure on the thread may burst, resulting in damage to the crane or axlebox mixer.

Further decorative nut is screwed. The valve is installed in its place and securely fixed by a securing screw, which is put on the decorative cap. After all the work opens the water supply and the tap is done checking for leaks.

Important!To change the direction of movement of head parts when opening, it must unscrew the locking screw, which then must be attached to the back side.

Important advice and tips on replacing head parts in the mixer

When deciding how to unscrew the head parts, you can face the problem of kick is an element to the body of the mixer, which is the result of rust or oxidation. To exit from this situation, there are several ways. The housing can be treated with vinegar, oxygen-containing compounds, or chemical means. It is also heated by building a hair dryer. Head parts can shatter with little effort. Pereuserdstvovanie often leads to damage of the element and the mixer.

Useful advice!As a last resort, used drilling head gate, but after such a procedure will cut new screw connection is necessary.

In the case of formation of cracks, chips, pits, or other damage to the seat of the worm head parts central element needs to be fully replaced. If you have problems with integrity or ceramic ball head gate, it needs to be replaced with a new one because the renovation of the indoor unit is not possible.

If there was an unpleasant creaking at the tap or to rotate the valve is necessary to make efforts for the solution of this problem must be lubricated with a head gate, which will prevent further damage to it. In identifying leaks from valves need to replace the rubber gasket. To do this, you can manually cut the required size piece of thick rubber or acquire a crane-Kit axlebox with sealing rings with different diameters in specialty store.

In case of detection after extraction crane axlebox abrasion adjustment items missing part can be extended with a thin silicone layer. After setting the composition of gate head screwed back.

As the head parts repaired ceramic type

Between crane axlebox ceramic discs may be sand or other mechanical impurities which will cause of leakage mating surfaces, whereby the plumbing element is proceed. To eliminate such a problem can be after the dismantling of the journal box and the dismantling of a head. Every plate is thoroughly cleaned and lubricated with a water-resistant structure. Repaired ceramic crane axlebox assembly is going back.

Important!When disassembling the ceramic axle boxes important not to confuse the bottom and top drive, as it will lead to incorrect operation of the device.

If the disc found small scratches and cracks, remove them possible by grinding the base. Repair crane axlebox performed using slightly tapered grit powder 1200, which is composed of silicon carbide and aluminum oxide. Powder before beginning the procedure should be to fill any glass. As the solvent used engine oil. Further taken damaged plate is applied to the glass, and it rubs against the circular motion. After the disappearance of all the scratch disk is rinsed under running water.

Located between the ceramic disks pressing plate which can be PTFE, nylon or polypropylene. The item undergoes a constant load, which leads to its deterioration. Reducing the thickness reduces the density of abutment assemblies. A gap is formed, which is leaking water.

The item can be replaced by a new one. For this purpose, the journal box completely disassembled crane, pull rod, the locking ring and the plastic washer. After installing the new washer discs should be cleaned and lubricated. If unable to find a suitable size item, it is possible to increase the thickness by sticking it on tape layer or by placing it under a thin circle of polyethylene.

In the case of housing depreciation, stock-tap, thread damage or the presence of significant scratches on discs repair head parts with your hands is not possible. The head must be replaced with a new element.
