The invention relates to the field of hydraulics, in particular, to a valve, such as metering devices, each jaw-whisker wash, etc., i.e. where it is required to ensure long and reliable operation without harmful water leaks.

Known float shut-off device with a variable water flow, comprising a housing with a cover and two valves, one of which is installed on the supply pipe and the other on the drain hole. The first concerned with the lever, at the opposite end of which is strengthened float, and a second valve in communication with the handle means mounted in the guide bushing piston rod protrusion interacting with reeds spring. The intake and exhaust valves are shut-off elements, opening and overlying communicating sections depending on the mode of the device (see USSR author's certificate N 1502732).

This device does not allow for a reliable and long-term work, because the locking elements of both valves from frequent interaction with solid valve components lose their working properties and require frequent replacement, otherwise there are useless water leaks.

The closest analogue to the claimed invention is a float shut-off device comprising a housing with a cover, a valve mounted on the supply pipe, and a stop valve installed on the discharge pipe. Valve mounted on the supply pipe communicates with the lever at the opposite end of which is placed a float located in the additional capacity is moveable in a vertical plane.

In additional capacity also contrabandista USSR N 382798).

This device does not allow to ensure reliable operation over an extended period of operation, because of its shut-off body from frequent interaction with the protrusion made on the return pipe, loses its working properties and requires replacement, and possibly the destruction of the ledge that leads to useless water leaks.

The objective of the invention is to provide a float shut-off devices, providing reliable operation over a long period of time without requiring frequent replacement of the sealing elements of the valve and eliminating useless water leaks.

The technical result of the invention is achieved due to the fact that the locking body is installed on the drain pipe, water seal is formed when the device, with the valve installed on the supply pipe has a kinematic connection with a driving element shutdown valve installed on the discharge pipe, which allows for additional manual force to eliminate the possibility of the effect of sticking the sealing elements of the valve, since the latter can be made of ceramic, which not only has good long-term sealing performance, but also increased the friction is the material, where in Fig. 1 shows the float shut-off device, in the closed position; Fig. 2 - the same, the position of the discharge of water; Fig. 3 - the same, an intermediate position.

Float shut-off device, mainly for a tank of the toilet with the housing 1 and the cover 2 contains a supply pipe 3 connected to the valve 4 with the lever 5 connected to the float 6 and mounted on the discharge pipe 7 serving inside of the housing 1, the locking body associated with a drive element.

Locking the body in the form of covering with a gap protruding section of the drain pipe 7 inverted Cup 8, provided with an additional float 9 attached on the periphery of its open end, an inverted Cup 8 with a gap in its perimeter has two coaxially arranged cylindrical shells 10, 11, are tightly interconnected in the upper part with the formation of the annular cavity 12, the latter acting on the area of the drain pipe 7 is fixed cylindrical Cup 13 with a Central opening in the base for connection with a drain pipe 7, the ends of the drain pipe 7 and a cylindrical Cup 13 are located on the same level, the drive element is designed as a vertically located intraline the bottom of the inverted Cup 8 connected to its internal cavity 16 to the atmosphere, the float 6 is made in the form of a covering with a gap inverted Cup 8 ring 17 to the hub 18 for landing on the tube 14 between the stop 15 and the bottom of the Cup 8, the lever 5 of the valve is made telescopic, with the possibility of changing the length and the hinge (hinge not shown) attached to the hub 18 of the float 6, and an inverted Cup 8 is installed with the possibility of a limited vertical movement through Sabaoani element 19 attached to the bottom of the housing 1 tank or to the bottom of the drain pipe 7 with ensuring contact with additional float 9 in the extreme upper position of the inverted Cup 8.

Float shut-off device is operated as follows.

In the closed position, when the body 1 of the device is filled with water from the water supply system through the supply pipe 3, a glass of 8 shells 10 and 11 are located in the extreme upper position defined skoboobraznye elements 19. The water level in the tank is regulated by the position of the float 6, the water may not act in the cavity of the housing 1 or in the drain pipe 7, since the latter prevents hydraulic lock, which is formed in the annular cavity 12 of the upper part of the shells 10, 11.

/ establishment, which she ignored with a gap. To avoid distortion of the tube 14, the cover 2 may be provided with a sleeve of antifriction material. Together with the tube 14 fall down inverted Cup 8, United with him shells 10 and 11 and the float 6 to the hub 18. This power influences the air between the walls of the glass 8 and the shell 10 is removed, and the resulting siphon channel water from the cavity of the housing 1 flows into the drain pipe 7. To ensure beschryvinge water flow area flow area between the walls of the glass 8 and the shell 10 perform more of the cross-section area of the drain pipe 7.

This hub 18 acts on the lever 5, causes the opening of valve 4, and water is supplied into the cavity of the housing 1. The lever 5 is made telescopic, for example, in the form of a rod inserted into the tube with the end in the form of a fork with holes covering the rods protruding from the housing hub 18, forming a hinged connection, it provides the ability to change the length of the arm 5 and the vertical movement of the tube 14.

The hub 18 is moved downwards under the action of the stop 15, which is mounted on the tube 14 so that the hub 18 when the float to move up 6 does not touch the stop 15, i.e., the valve 4 is transposable more tender opening valve 4.

When filling of the housing 1 with water first, under the additional action of the float 9 is moved upward inverted Cup 8 shells 10 and 11 until the level defined by the stops 19 and the float 6 remains in place in the lowest position held by the lever 5, so the valve 4 is fully open as long as the water level in the housing 1 reaches the float 6, after which the latter, in turn, lifts up and closes the valve 4, i.e., the device is ready for subsequent work.

The buoyancy of the float 6 is selected from a condition of maintenance of the water level in the housing 1, not to exceed a level corresponding to the connection at the top of the shells 10 and 11, the same result can be achieved by adjusting valve 4, for example, changing the weight of the lever 5, while if the valve 4 skips for some reason the water, then its possible overflow into the drain pipe does not require additional overflow tube (safety valve). The ring 17 of the float 6 may be made hollow, filled with buoyant material (cork, foam and others).

The tube 14 can be provided with a cap (not shown), providing the convenience in operation, but it is necessary to save the message with the atmosphere inside the while (siphonaria) message cavity 16 of the inverted Cup 8 with the atmosphere eliminated by closing the end of the tube 14 by a phalanx of a finger or by means of the above-mentioned cap, role valve.

Drain water from the housing 1 can be stopped at any time (which is very important in terms of savings in water consumption) by removing the pressure of his hands on the tube 14 (drive). In this case, a channel of communication with the atmosphere of the cavity 16 of the inverted Cup 8 through the tube 14 opens, ie, the depressurization of the siphon channel and the flow of water stops.
