The utility model comprises a connector 11, a rubber ring 10, a guiding valve body 5 and a valve clack 8 which is arranged in the guiding valve body 5 and is matched with the rubber ring 10 to perform a sealing function, and the rubber ring 10 and the guiding valve body 5 are fixed to the connector 11, wherein, the contact part of the sealed end of the lower part of the valve clack 8 and the rubber ring 10 is in the shape of a horn, and an inner ring of the rubber ring 10 is provided with a sealing ring 13. The utility model has the advantages of long service life and favorable sealing effect.

Description

Controllable water saving valve for water flushing cistern

The utility model relates to a kind of valve, especially a kind of controlled water-saving valve that is used on the flushing cistern.

Water plays an important role in the middle of industrial and agricultural production and people's lives.Domestic in recent years the greater part freshwater resources are obviously not enough, and many cities are subjected to the lack of water puzzlement, industrial production and resident living are impacted, so townsfolk's using water wisely are the task of top priority.In order to reach water-saving purpose, at present relevant producer has done improvement to the valve on the employed flushing cistern of resident, original flushing cistern, when spurring valve towards urinal, water in the water tank will all bleed off, and then from newly being full of tap water, this mode, relatively waste the water source, and improve the back structure be: (name as Patent Office of the People's Republic of China's one nine nine zero year bulletins on May 23 is called " lavatory flushing cistern ") fixes a valve at water tank bottom, the elastic packing valve seat is housed in the housing of valve, be placed with valve plug on the valve seat, the bottom sealed end of valve plug is hemispherical and seals with elastic packing valve seat line style, so it is pointed that the top edge of elastic packing valve seat is necessary for, though this structure can artificially be controlled when flushing toilet bowl, when flushing finishes, can stop flushing, unlikely water in the water tank is all bled off, but this structure just uses effect bad, particularly when the valve plug unlatching, water all around is fast by concentrate and the top edge of impact elasticity seal valve seat to the center herein, the effect of flushing process suction in addition, make the distortion of elastic packing valve seat top edge, phenomenon can take place to roll in long-term the use, therefore cause closing malfunctioning, the valve of this structure is short application life.

The purpose of this utility model provides the controlled water-saving valve of a kind of long-lived flushing cistern.

The utility model technical solution is: the controlled water-saving valve of a kind of flushing cistern, it comprises connector, is fixed on the cushion rubber on the connector and the valve body that leads, places the valve that seals that matches with cushion rubber in the guiding valve body to distinguish, described valve distinguishes that lower closed end and described cushion rubber touching position are horn-like, and the inner ring of cushion rubber is provided with joint ring.

The utility model compared with prior art because valve distinguishes with the cushion rubber touching position and be horn-like, during use, current are along its edge and therefore mistake has no damage to the cushion rubber that seals in flushing process, have that sealing is reliable, the advantage of long service life.

Below in conjunction with the drawings and the specific embodiments the utility model is further described:

Fig. 1 is the front view of the utility model specific embodiment;

Fig. 2 is the profile of cushion rubber 10;

Fig. 3 is that valve distinguishes that 8 are landed in the profile after cushion rubber 10 deforms on the cushion rubber 10.

As Fig. 1 institute: 11 is connector, and the bottom of connector 11 is provided with screw thread, with nut 2, sealing

mat

3,4 connector 11 is fixed at the bottom of the water tank on 12, and the lower end of connector 11 is provided with nut 1, can join with the water pipe that leads to urinal.Inboard, connector 11 upper end is provided with internal thread, with bung flange 14 cushion rubber 10 is fixed on the connector 11.The outside, connector 11 upper ends is provided with external screw thread and is threaded with guiding valve body 5, and the sidewall of guiding valve body 5 is provided with equally distributed water inlet slotted hole (as shown in Figure 1).Place the valve in the guiding valve body 5 to distinguish that 8 upper ends are tubular, the bottom is horn-like, the line spiral shell was threaded with guiding bleed off pipe 6 in lowermost end was provided with, guiding bleed off pipe 6 upper ends are stretched out also and can axially be moved up and down from the loam cake of the valve body 5 that leads, distinguish that in order to make valve 8 have constant weight, valve distinguishes that 8 inner chamber is equipped with counterweight 9, suitable for readingly is stamped 7.In order to have good sealing effectiveness, the inner ring of cushion rubber 10 is provided with joint ring 13, joint ring 13 and cushion rubber 10 be structure as a whole (referring to Fig. 2, Fig. 3).

Spur guiding bleed off pipe 6 with stay cord during use, bleed off pipe 6 drives valves and distinguishes that 8 move in guiding valve body 5, the inlet opening of water in the water tank on valve body 5 sides of leading enters guiding valve body 5 inner chambers, again from valve distinguish 8 and cushion rubber 10 between formed gap go out downwards by connector 11 endoporus, when flushing finishes, at any time decontrol stay cord, valve distinguishes that 8 fall to sealing.

The utility model is not only limited to above-mentioned embodiment, and any possible mode all belongs to basic thought of the present utility model.

Claims
