Valve for filling water tanks

 

(57) Abstract:

The invention relates to sanitary fittings, in particular to the filling valves for flush tanks tanks. The technical result is that the proposed design of the valve is bespolovogo and as a result, the reliability of the valve and the control accuracy of the water level in the tank increases. The valve includes a housing mounted on the inlet pipe, a saddle, a membrane with a Central hole coaxial to the saddle, and the output nozzle. The case is additionally connected to the diaphragm of the camera is divided into two hollow elastic membrane, which is bonded with a hard disk, and has mounted to it an elastic valve. The location of the last coaxially made in the front wall of the chamber calibrated hole. In the lower part of the wall of the front half posted by outlet, the wall mounted arm with a spring supported in the disk membrane. The rear half of the chamber is provided with a pipe of the coaxial arrangement of the seat and connected with an air tube, the inlet of which is located at a level corresponding to the minimum water level in the tank. 1 Il.

Known filling the float device with a valve or membrane locking element, lockable lifting force of the float (see, for example, O. P. Mikheev "Design of sanitary water fittings buildings" M, stroiizdat, 1990, pp. 50 - 51, Fig. 26) [1].

Known for such designs float devices, valve or membrane locking elements which are locked by the pressure of the water, these include the well-known float valve device selected by the authors as a prototype, which includes a housing mounted on the inlet pipe, saddle, locking element in the form of an elastic membrane with a Central calibrated hole coaxially seat, lever-float mechanism and the outlet (see O. P. Mikheev "Design of sanitary water fittings buildings" M, stroiizdat, 1990, Fig. 27G) [2].

Used in a known design lever-float mechanism may not provide the necessary accuracy of water level control in capacity and reliability of operation of the valve.

This technical result is achieved by the fact that in the known device the valve to fill the water tanks, mainly, flush b is m the saddle, and outlet, the body is additionally connected to the diaphragm of the camera is divided into two hollow elastic membrane, which is bonded with a hard disk, and has mounted to it an elastic valve, the location of which is coaxially made in the front wall of the chamber calibrated hole, and in the lower part of the wall of the front half posted by outlet in the wall of the spiral arm with a spring supported in the disk membrane, while the rear half of the chamber is provided with a pipe of the coaxial arrangement of the seat and connected with an air tube, the inlet of which is located at a level corresponding to the minimum water level in the tank.

The drawing shows the inventive filling valve in the cut. The valve includes an inlet fitting 1, nuts 2, by means of which the valve is attached to the tank 3 with the cover 4, the saddle with ribs 5, the elastic membrane 8 with a calibrated orifice 7, screw the handle 9, the spring 10, the elastic membrane 12 made in one piece with the disk 11, a valve 14, a calibrated orifice 13, the air pipe 15, the air tube 16, the discharge opening 17, the outlet 18, pipe 19, the housing 20.

The principle announced the th in the air pipe 16 and the pipe 15, the membrane 12 with the disk 11 and the valve 14 closes the opening 13.

Water coming from the water in the pipe 1, the saddle 6 and the hole 7, fills the cavity behind the membrane 8 and presses it to the seat 6 by the difference in effort for the membrane and in front of her. The supply of water in the tank 3 is stopped.

During emptying of the tank 3 to the minimum water level in the tank, an air pipe 16 and the pipe 15 is set to the atmospheric pressure.

The water pressure in front of the hole 13 opens the valve 14. The pressure in the cavity behind the membrane 8 falls and by the difference in effort before and after the membrane 8, the saddle 6 is opened and the water between the ribs 5 through pipe 18 and pipe 19 enters the tank 3, filling it with water to the maximum level. Then, as described above, the membrane 8 closes the saddle 6. A small amount of water coming from an open valve 14 through the opening 13, is discharged into the tank through the opening 17. Rotating spiral arm 9, thereby compressing or closing spring 10, adjust the maximum water level in the reservoir due to changes in the difference of effort before and after the membrane 12 with the disk 11.

The ribs 5 on the 6 saddle reduce the noise level when filling the tank with water and protect the membrane 8 from excessive strain is achieved by replacing the lever-float mechanism in the known device the valve diaphragm chamber, controls air pressure in themembrane chamber and an air tube provided with a spring, the efforts of which is adjusted by a screw handle.

Valve for filling water tanks, mainly the flush-water tank, comprising a housing mounted on the inlet pipe, a saddle, a membrane with a Central hole coaxial with the seat and the outlet, wherein the housing is additionally connected to the diaphragm of the camera is divided into two hollow elastic membrane, which is bonded with a hard disk, and has mounted to it an elastic valve, the location of which is coaxially made in the front wall of the chamber calibrated hole, and in the lower part of the wall of the front half posted by outlet, the wall mounted arm with a spring supported in the disk membrane, while the rear half of the chamber is provided with a pipe of the coaxial arrangement of the seat and connected with an air tube, the inlet of which is located at a level corresponding to the minimum water level in the tank.

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.
