The invention relates to sanitary-technical equipment and can be used in water supply systems, in particular, in the taps-faucets.

Known discharge device used in mixers, consisting of a tank with saddle and outlet is located inside of the tank for dispensing and automatic opening and closing of the outlet device made in the form of a spherical valve positive buoyancy and the l-shaped float, interconnected by a flexible shaft (RU, patent N2005140, class E 03 C 1/04, 1993)aerovane air, uncertain orientation relative to the seat and increase the size of the crane.

The closest to the technical nature of the effect is achieved is known mixer taps, in which the discharge device made in the form of a tank with saddle and outlet is located inside of the tank for dispensing and automatic opening and closing of the outlet, the device made in the form of a spherical valve positive buoyancy and siphon tube with a drainage hole at the top of the bend, while the discharge end of the siphon tube is connected with the channel in the body of the tank communicating with the outlet below the valve (EN, N2005139, class E 03 C 1/04,1993).

The main disadvantage of this faucet-faucet is the limited capacity of trenirovki through the siphon tube and the associated limited scope periodicity water drainage, and the presence of far-acting elements in the faucet-mixer, increasing its dimensions.

Object of the invention is the expansion of technological capabilities and reliability of faucets and water saving. This task is solved in that in the mixer, comprising a housing with inlet and outlet nozzles, valves, the systematic opening and closing of the outlet, drainage system, the drainage system is made in the form of additionally installed on the dispensing device and automatic opening and closing of the outlet symmetrically curved drainage tube with cut vertex on the upper part of the bend, the ends of the tube are communicated through channels made in the bottom of the tank with the outlet, the cross-sectional area of the orifice tube in the plane of the slice, not less than twice the area of the holes in the cross-section of the tube.

In Fig. 1 shows a General view of the mixer of Fig.2 section BB on the housing of the mixer of Fig.1 with the image of the crane switch water shower on the drain tube (and Vice versa), Fig.3 a section along AA of Fig.1, in Fig.4 view In Fig.3, in Fig.5 drain the tank with a device for dispensing and automatic opening and closing of the outlet, made in the form of a spherical valve with positive buoyancy and the l-shaped float connected with the valve, a flexible shaft of Fig.6 depicts the layout is lightweight flush tank at the end of the drain tube of the mixer of Fig.7 depicts a mixer for sink, and Fig.8 type G figure 8.

The mixer (Fig. 1,3,5) consists of a body 1 with the valves 2 and output is to the body 1. The outlet 4 of the mixer by means of the reducer 7 is connected with the base 5, which made the inlet 8, the outlet 9 and 10 under saddle valve 11.

Inside the toilet tank is placed a device for dispensing water and an automatic opening and closing of the outlet 9.

In Fig. 1 this device is designed as a spherical valve 11 with positive buoyancy and siphon tube 12 communicating at one end with the outlet 9 through the openings 13 and 14 made in the base 5 of the drain tank. The opening 14 extends under the base of the valve 11 at right or acute angle to the axis of the outlet 9.

In Fig.5, the device for dispensing is made in the form such as spherical valve 11 with positive buoyancy and the l-shaped float 15 with the projection 16, which is located in the zone of the axis of rotation of the float 15. The float 15 is equipped with a drum 17 has a slide on which is wound a flexible rod 18, connected with the valve 11. Flexible rod 18 is located in the slot of the float 15, and its movement in the slot is limited by the protrusions 19 and 20. Inside the toilet tank (Fig. 1,3,5) posted by drain pipe 21 located above the dispensing device and the automatic is and the upper part of the bend. Both ends of the drainage tube 21 are mounted in the base 5 and is communicated with the outlet 9 through the openings 23 and 24, made in the base 5. The cross-sectional area of the orifice tube 21 in the plane of the slice 22 is not less than twice the area of the holes in the cross-section of the tube.

Spherical valve 11 and the saddle 10 in both devices are designed so that when the positive buoyancy of the valve 11 is held in the saddle and nothing POPs up due to the fact that the buoyancy force on the flooded part of the valve, is less than the weight of the valve. Additionally, a pair of valve 11 with the saddle 10 negerlein (which is possible, since the tank is located behind the gates at the discharge).

In Fig.2 shows a variant of the crane switch water through the shower drain or the drain tube at the location of the output nozzles 3 and 4 at an angle of 90o. It consists of a fixed sleeve 25 and the valve 26 can be rotated when the rotation of the handle 27. The spool 26 is made connecting holes 28 and 29 and the longitudinal channels 30 and 31 interconnected in the area of the outlet valve 26 into the outlet pipe 4 (not shown).

In Fig.6 depicts accommodation drain tank directly Erial (titanium, aluminium alloys or plastic) and reduced size. The crane switch water remains current as the drain tube will be connected to the pipe 4, already located at the bottom of housing 1. Presents mixer equipped with advanced locking devices located at the inlet 32 before lockable valves 2 holes. The locking device consists of a hollow body 33 connected to the input hole of the socket 32 of the mixer and placed inside the housing 33 of the valve 34 with positive buoyancy. Pair valve 34 is overlapped with the valve hole in the inlet pipe 32 negerlein.

In the upper part of the housing 35 has a screw 36 with a cone on the end, overlying the inner vent hole 37. Radially to the screw 36 in the housing 35 is made outside the vent hole 37. The valve 34 is made with the possibility of free sinking to the bottom of the cavity inlet pipe 32 leakage of water from the system.

In Fig. 7 and 8 shows the layout of the mixer for sink using the above-described drain flushing device for dispensing and automatic opening and closing of the outlet and shut-off devices. The designation position is that hot and cold water in the pipe, communicated with the cavity of the housing 33 of the locking device. In the area of the tear-out in Fig.8 shows a hole 39 through which the water flows through the adapter 7, made in the form of a square, in the tank.

The operation of the mixer is as follows. In the initial position the valves 11 are located in the saddle 10 and block the outlet 9. The valve 34 is in its extreme upper position. The hole in the inlet 32 from the side of the highway with water opened, and the valves are closed. When the small opening of the valves (one or both) and rotation of the arm 27 by draining the water through the drain tube (Fig.2) water is directed through the longitudinal channels 30 and 31 of the valve 26, the outlet pipe 4, the transition pipe 7 and the hole 8 of the base 5 in the tank, flooding the valve 11, which is still located in the saddle 10, at the beginning due to the fact that the weight of the valve is greater buoyancy force acting on the flooded part of the valve 11, and then through the liquid column, holding additional valve 11 to the seat 10. Rising water level in the drain tank air freely expelled through the drain pipe 21 and the holes 23 and 24 into the outlet 9.

This flooded the device the level of (siphon sunk not less than 2/3 of the cross section of the hole) (Fig. 1, 2) in a siphon tube 21 is positive, i.e., an automatic drain water leaks through the tube 21, the holes 23 and 24 and then into the outlet 9. In the area of the exit of water from the openings 24 into the outlet 9 is turbulent swirl of water from the sudden changes of direction and expiration valve 11 is already flooded with two sides. The pressure on the valve is aligned and it automatically POPs up, opening additional drain through the saddle 10. From this point of drain water is carried out simultaneously two holes: through hole of the seat 10 and through the siphon tube 21. By reducing the water level to the edge of the free end of the siphon tube 21 remains only after through the hole of the saddle 10. With further lowering of the water level valve 11 is drawn into the saddle 10 and closes the outlet 9. The valve 11 is enclosed in the space between the surfaces of the siphon and drain pipes can't get out of this space, and therefore the discharge is reliably lowered only in the saddle 10. And so the periodic accumulation of water in the drain tank and the sharp discharge continues until you close the valves. When water enters the tank according to Fig.5, the valve 11 in the same manner charged in the saddle 10,the tank is also expelled through the drain tube 21 and the holes 23 (not shown) and the hole 24.

During the flooding of the projection 16 of the float 15 starts to rotate in the position of unstable equilibrium, and clicking it makes a sharp turn, pulling the flexible rod 18 and opening the valve 11 from its seat. The float 15 is at the upper position, resting on the casing 6, and the valve 11 floats on the surface of the water. Drain the water from the tank through the outlet 9. Liberating in spill reservoir space is compensated by air suction through the openings 23 and 24 and the drain tube 21 and partially continuously flowing water in the tank through the opening 8. In the process of draining the water and reduce its level, the valve 11 is lowered down and pulled water into the saddle 10 and the float 15 is returned to its original position. And so the process of periodic discharge is repeated until you have closed the valves. Flexible rod 18 is selected such lengths to ensure the free position of the valve 11 in the saddle (without tension thread) and to the time of commencement of sharp turning of the float 15 no tension. And just at the moment close to the maximum kinetic energy of the float, a flexible rod is in tension. The calculation of the length of the flexible rod prevents the valve 11 to fall apart saddles 10 and provides reliable separation of the valve 11. For bespec holes, and the outlet 9 to perform the cross-section larger (about 10-30%) of the total cross section of the drain holes from the seat 10 and the siphon tube holes 24 for a tank of Fig.1 and 3.

In the waste-holding tank of Fig.5 drain outlet 9 is only through one hole (seat 10), which is significantly less than the cross-section of the outlet 9. The frequency of discharge depends on the degree of opening of the valves. The more you open the valve, the more will be periodic draining, until, finally, comes the continuous draining. In this position, the valve 11 will always be out of the saddle 10 and the float 15 (Fig.5) in the extreme upper position. For emergency discharge of water (when the mixer mode periodic discharge) before filling full dose of water, in which there is an automatic system operation the drain, enough to cover the palm or finger hole drain tube (or the outlet 9 of the drain tank is mounted at the end of the drain tube Fig.6). When this is aligned with the pressure acting on the valve 11 at the top and bottom and it breaks away from the saddle 10 and abruptly POPs up. When the mixer valve 34 (Fig. 3) is always in the upper position and does not interfere in pipe 32 and remains in this position until the water supply.

When water and closed valve valve 34 POPs up in the body cavity 33. Before operating the mixer in this case, you must turn on 0,5-1 turnover screw 36 and to release from the housing 33 of the air, so that the water and the valve 34 will occupy the topmost position, if it does not run, then when the valve is opened, the valve 34 will become addicted to the flow of water into the cavity inlet pipe 32 and block the hole of the valve. The screw 36 after trenirovki again lock hole 37. When water in the system, but when the valve is not closed, valve 34 under the action of a stream of water rushes to the hole (behind the gate) and overlaps it, eliminating flooding and a large wastage of water. When water in the system it is necessary to close the valve, and the valve 34 POPs up automatically in the body cavity 33. It now remains to only perform the above operation to drain air from the housing 33 by means of screws 36. The valve will occupy the topmost position and will remain there until until you turn it off the water supply.

Instead of the screw 36 can install a drain valve that automatically maintains air back and forth, but experience shows that in terms of working with these water valves eventually cease RA is ing work significantly expand its technological capabilities and consumer properties.

It features water saving due to the periodic discharge, in which the opening of the valves is minimal, and draining the water as with a large opening of the valves. This is ensured by the accumulation of water during the period when it is not required and a single full discharge. The mixer allows you to easily and emergency draining of the water with a simple touch of his hand or finger to the drain tube. In addition, a locking device makes the safe operation of the mixer in the conditions, when often cut off the water. It eliminates the potential for flooding of the premises and of the great loss of water. Per hour of water discharge through the open one faucet poured about 1 m3water.

The proposed mixer saves without alteration of the functional properties of existing mixers regardless of whether you will or will not work with new devices that fit into the dimensions of these mixers and does not change fundamentally the structure of all the main sites. Saved and all connecting elements. Without any alteration of communications you can replace the existing faucet at the proposed mixer. New elements of the proposed mixer in the priori device). Each operates independently from each other. If necessary, you may use one of them. The same appreciation mixer compensated consumer properties, providing savings of water, excluding water losses during unclosed cranes and material and moral damages from flooding their offices and premises in lower floors.

From the point of view of safety of operation of the proposed mixer solves security problems and this raises the question of the validity of the production and use of existing mixers in the interests of the consumer.

Mixer, comprising a housing with inlet nozzles, valves, drain the tank with saddle and outlet and placed in a tank device for dispensing and automatic opening and closing of the outlet, the drainage system, characterized in that the drainage system is made in the form of an optionally installed on the dispensing device and automatic opening and closing of the inlet symmetrically curved drainage tube with cut vertex on the upper part of the bend, the ends of the drainage tube is communicated through the channels made is less than twice the area of the holes in the cross-section of the tube.
