(57) Abstract:

The invention relates to a sanitary fixture and can be used for automatic filling with water flush tanks or other containers. Bespopovtsy filling valve includes inlet pipe, casing seat, the elastic membrane with a hole, an outlet, a control diaphragm chamber, consisting of two cavities separated by a membrane, which is rigidly fastened to the arm with an elastic valve, the change of the efforts of the shoulders of regulate lever spring screw handle, and to the inlet pipe is sealed bent at a right angle inlet pipe fixed in the hole of the wall of the tank above the maximum water level in the tank, and in the wall of the control chamber of the diaphragm before the diaphragm is made of the pipe on which the sealed tube, end of which is displayed above the maximum water level in the tank. This valve design provides increased reliability, improves performance and reduces water loss during operation. 1 Il.

The invention relates to sanitary-technical equipment and can be used for automattician, comprising a housing with inlet and outlet nozzles, shut-off element in the form of an elastic membrane with a calibrated orifice and lever-float control valve (O. P. Mikheev. Design of sanitary water fittings buildings. Moscow, Stroyizdat, 1990, S. 52).

However, in the known construction is not enough reliable regulating lever-float valve and do not provide 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 (tank).

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 obna the applicability of the proposed bespolovogo filling valve is provided for those it contains inlet pipe, casing seat, the elastic membrane with a Central hole, an outlet, and a valve provided with a control diaphragm chamber, consisting of two cavities separated by a membrane, which is rigidly fastened to the arm with an elastic valve, the change of the efforts of the shoulders of regulate lever spring screw handle, and to the inlet pipe with Union nut is sealed bent at a right angle inlet pipe fixed in the hole of the wall of the tank with nuts and gaskets above the maximum water level in the tank, and in the wall of the control chamber of the diaphragm before the diaphragm is made nozzle, on which the sealed tube, the end of which is displayed above the maximum water level in the tank.

The drawing shows the claimed bespopovtsy filling valve in the section.

The valve includes an input tube 1, the nut 2 with a gasket 3, tank 4 with the lid 5, slip the nut 6, the inlet 7, an exhaust pipe 8, the saddle 10 with ribs 9, the elastic membrane 12 with a Central hole 11, the hole 13, screw the handle 14, the spring 15, the stop 16, the elastic valve 17, the hole 18, the lever 19, a ROM 20, a cover 21, a diaphragm 22, a housing 23, S="ptx2">

In a water-filled tank 4 to the maximum level, the water fills the through hole 13 of the cavity chamber of the diaphragm with the diaphragm 22. The hydrostatic pressure of the water layer in the tank press the membrane 22 and the disk 20 up connected with the drive lever 19 with the elastic valve 17 closes the opening 18. Thus, the atmospheric pressure above the diaphragm 22 is provided with a branch pipe 24 and tube 25. Water from the water supply through the inlet tube 1, the inlet pipe 7, the saddle 10 and the hole 11, fills the cavity behind the flexible membrane 12 and presses it to the seat 10 by the difference in effort for the elastic membrane 12 and in front of her. The supply of water in the tank 4 is terminated. During emptying of the tank 4 to a minimum level of hydrostatic pressure behind the membrane 22 is reduced, the pressure of the water in front of the hole 18 opens elastic valve 17. The pressure in the cavity behind the flexible membrane 12 falls and by the difference in effort before and after the membrane 12 of the seat 10 is opened and the water between the ribs 9 through an outlet pipe 8 enters the tank 4, filling it with water to the maximum level, after which, as stated above, the elastic membrane 12 closes the saddle 10. Rotating screw the handle 14 and clenching or unclenching spring 15, you can regulirovaniya 16. Ribs 9 on the saddle 10 reduce the noise level when filling the tank with water and prevent the elastic membrane 12 from excessive stresses when closing the seat.

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, characterized in that it is supplied with control diaphragm chamber, consisting of two cavities separated by a membrane, which is rigidly fastened to the arm with an elastic valve, the change of the efforts of the shoulders of regulate lever spring screw handle, and to the inlet pipe with Union nut is sealed bent at a right angle inlet tube, fixed in the hole of the wall of the tank with nuts and gaskets above the maximum water level in the tank, and in the wall of the control chamber of the diaphragm before the diaphragm is made of the pipe on which the sealed tube, the end of which is displayed above the maximum water level in the tank.

Filling float-valve // 2351835

FIELD: machine building.

SUBSTANCE: present invention pertains to hydro-automation, particularly to hydraulic inlet valves with dosed supply of liquid into a filling tank, and is meant for use in systems for filling different types of reservoir with water. The filling float-valve has housing with an inlet, an outlet opening and a seat inside the housing in form of a nozzle, a gate opposite the seat, in form of an elastic membrane with thickening in the area where it is in contact with the seat. The axially moveable coupling of the gate is on an arm support. The arm support is fixed against the housing using a cap nut and is kinematically linked to the float through a lever and a tie-rod. The float is fitted with provision for vertical displacement. The perimeter of the membrane is pressed into the housing by the arm support with a cap nut, forming a cavity in the housing on the side of the seat. The cavity is linked to the outlet opening and, through the nozzle, to the inlet. There is a cavity on the arm support above the membrane. This cavity is linked to the cavity in the housing through at least one opening on the membrane. The coupling rod is pressed against the arm support using stocking type sealing rings. Inside the cavity in the housing, on the side of the seat, an encircling seat is fitted, forming an annular gap, as well as a throttle insertion which is in form of a cup. A bypass hole is made at the bottom of the latter. The perimeter of the membrane is pressed between the bottom of the cup and the arm support. An outlet opening is made in the side wall of the cup. On the inner wall of the cup and the outer side surface of the seat there are radial ribs with formation by the latter in the annular gap, a labyrinth in the cross-section of the throttling channel.

EFFECT: increased reliability and easier operation of a filling float-valve.
