The invention relates to sanitary-technical equipment and can be used for automatic filling with water flush tanks or other containers.

Known p the elastic membrane with a calibrated orifice and lever-float control valve (O. P. Mikheev. Design of sanitary water fittings buildings. M.: stroiizdat, 1990, S. 52).

However, in the known construction is not enough reliable regulating lever-float valve and does not provide any easy and precise regulation of the water level in the tank.

The scope of application of the valve is limited by the ability of its fastening only on the side wall of the container (barrel).

The closest technical solution is bespopovtsy filling valve for automatic filling with water flush tanks or other containers, including inlet pipe, casing seat, the elastic membrane with a Central hole and an outlet (US 4707868, class E 03 D 3/10, from 24.11.87).

However, this bespopovtsy filling valve is more complicated and bulky in design.

Proposed bespopovtsy filling valve is devoid of the above disadvantages is the most industrially applicable, more reliable and provides sufficient facilities and precise regulation of the water level in the tank (the tank).

Industrial applicability the proposed bespolovogo filling kuperstein, exhaust pipe, and the casing is provided with a control diaphragm chamber, consisting of two chambers separated by an elastic membrane, which strengthened the hard disk and the arm with an elastic valve, the lever for the elastic valve based on the emphasis of the casing and the spring screw handle, upper part of the control chamber of the diaphragm in the cavity behind the flexible membrane has an elastic tank, a pipe which is inserted in a socket made in the lid of the control diaphragm chamber and hermetically connected with the air tube, the free end of which is located above the minimum water level in the tank, moreover, in the lower part of the control chamber of the diaphragm in the cavity for an elastic membrane made drain hole in the bottom of the cavity before the elastic membrane is made the hole, indicating that cavity with the atmosphere through the fins, made on the outer surface of the inlet pipe and the openings in the Union nut securing the valve to the tank corps.

The invention is illustrated in the drawing, which depicts bespopovtsy filling valve in the section.

Bespopovtsy filling valve includes inlet pipe 1, the nut 2 with hole 4, the Oh 12, the elastic membrane 13, a ROM 14, a cover 15, flat elastic container 16, pipe 17, the nut 18, the tube 19, the lever 20, the opening 21, the elastic valve 22, the stop 23, the spring 24, screw the handle 25, the hole 26 and ribs 27, the tube 28, the tube 29.

The principle of action of the claimed valve is as follows.

the 1st option. The valve is installed on the side wall of the tank above the maximum water level in it.

In a water-filled tank 11 to a maximum air pressure of the compressed water in the air tube 19 and the elastic container 16 presses the elastic membrane 13 and the ROM 14 to the left is bonded with the disk lever 20 with the elastic valve 22 closes the opening 21.

Water coming from the water in the inlet pipe 1, the saddle 7 and the hole 8, fills the cavity behind the elastic membrane 9 and presses it to the seat 7 by the difference in effort for the elastic membrane 9 and in front of her. The supply of water in the tank 11 is stopped. During emptying of the tank 11 to the lowest level in the air tube 19 and the elastic container 16 is set to the atmospheric pressure. The water pressure in front of the hole 21 opens elastic valve 22. The pressure in the cavity behind the elastic membrane 9 is falling and at the expense of razno 28 enters the tank 11, filling it with water to the maximum level after which, as stated above, the elastic membrane 9 closes the saddle 7. A small amount of water flowing in an open elastic valve 22 through the opening 21, is discharged into the tank through the opening 26.

Rotating screw the handle 25 and clenching or unclenching the spring 24 can be adjusted with high precision, the maximum level in the tank due to the change effort on the shoulders of the lever 20 between the stop 23.

Ribs 27 on the saddle 7 reduce the noise level when filling the tank with water and prevent the elastic membrane 9 from excessive stresses at the closing of the saddle.

the 2nd option. The valve is installed in the bottom of the tank as he mounted on the wall in 1 version. In this case, unscrewing the nut 18, the off-hook 19 by removing the cover 15, take out the elastic container 16 and again install the cover. Remove the tube 28 with the pipe 29. The valve is ready to operate with the lower water connections.

When filling the tank with water through the open seat 7 water also fills the through pipe 17 to the cavity behind the flexible membrane 13 and the ROM 14.

At the maximum water level in the reservoir under the influence of the hydrostatic pressure of the water layer elastic membrane 13, the ROM 14, the lever 20 has pressed 7 elastic membrane 9.

During emptying of the tank 11 hydrostatic pressure in the cavity behind the flexible membrane 13 and the ROM 14 decreases, the elastic valve 22 opens the hole 21 and the same as in the first embodiment, the elastic membrane 9 opens the saddle 7 and the water from the water supply through pipe 29 fills the tank 11 with water to the maximum level. Adjusting the water level in the tank is the same as in the first embodiment.

Bespopovtsy filling valve for automatic filling with water flush tanks or other containers, including inlet pipe, casing seat, the elastic membrane with a Central hole and an outlet, wherein the housing is equipped with control diaphragm chamber, consisting of two chambers separated by an elastic membrane, which strengthened the hard disk and the arm with an elastic valve, the lever for the elastic valve based on the emphasis of the casing and the spring screw handle, upper part of the control chamber of the diaphragm in the cavity for the elastic membrane has an elastic cylinder, a pipe which is inserted in the socket, made in the lid of the control chamber of the diaphragm, and hermetically connected with the air tube, the free end of which location is patterned, performed the drain hole in the bottom of the cavity before the elastic membrane is made the hole, indicating that cavity with the atmosphere through the fins, made on the outer surface of the inlet pipe and the openings in the Union nut securing the valve to the tank corps.
