Abstract
The utility model relates to a leakproof discharge valve for cisterns, comprising a start-stop mechanism and a water sealing mechanism. The start-stop mechanism is connected up by a switch which is fixed on a cistern, an operating rod and a control device with a floating ball. The water sealing mechanism comprises a valve seat which is provided with an overflow pipe and is tightly matched with a sealing device with positioning rods. A control rod on the upper end of the leakproof discharge valve for cisterns is positioned by a guide sleeve. The valve seat and the sealing device on the lower end of the leakproof discharge valve for cisterns are positioned by the positioning rods, so the water leakage is thoroughly ensured. The leakproof stability can reach higher than 99.99%. The utility model can automatically start and stop to discharge water, and can reset after fixed quantity of water is discharged. Besides, the utility model can arbitrarily control the quantity of the discharged water in order to achieve the purpose of saving water. A sealing gasket can be used for a long time without deformation, so the service life is prolonged. The utility model is an ideal product for replacing the older generation of discharge valves for toilet cisterns.
Description
The utility model relates to the seal valve that a kind of sanitaryware water tank is used, water tank leakproof control amount draining valve.
Bring water supply volume to increase day by day along with improving constantly of sanitaryware utilization rate, be to solve the water resource of saves valuable, can provide uses, sanitaryware water tank easy to maintenance to people's life again, so relevant various water tank patents are arisen at the historic moment.
Patent No. 88205774.X " arc draining seal valve " uses inconvenience though better seal is arranged, and will pull switch with hand always and all just can let go after intact up to water tank water.
The patent No. 93219111.8 " water tank leakproof draining valve ", though can leakproof water-saving result good, easy to use, just can realize the draining automatic open and close as long as pull switch, quantitative draining resets, displacement can't be controlled arbitrarily according to actual needs.
The purpose of this utility model is to provide a kind of " water tank leakproof control amount draining valve ", and its leakproof good stability is easy to use, but structure is simpler, and displacement what can control according to actual needs, and water-saving result is remarkable.
The utility model is achieved in that water tank leakproof control amount draining valve is made up of mechanism for opening/closing and water sealing mechanism, and by the switch that is fixed on the water tank, action bars, fairlead and the control device that has a ball float connect and compose mechanism for opening/closing, and being closely cooperated by the sealing device of the valve seat of band overflow pipe and band backstay constitutes water sealing mechanism.
Accompanying drawing, structural representation of the present utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Control device is that the cross section is rectangle, and the control lever (2) of chute is arranged on the surface, and control device also can be structures such as circular pull bar or stay cord.Fairlead (3) one lateral sections are the oblong aperture frame that is complementary with control lever (2), and the slide block of respective slide slots is arranged on the inwall, and side is fixed on the overflow pipe (11) in addition.Ball float (4) is the agaric shape, also can be spheroid or other shape.
Control lever (2) upper end interlocks with action bars (1) one end activity, and the side that fairlead (3) is passed in the lower end flexibly connects the mechanism for opening/closing that also can be fixedly connected into integral body with pin and ball float (4).
Compacting stationary positioned bar (9) in the middle of the valve gap (5), sealing mat (6) is made by soft elastic caoutchouc.
Backstay (9) on the valve gap (5) passes the through hole in the middle of sealing mat (6), the pressure cap (7), is fixed into whole sealing device with nut.
Valve seat (8) is the cylindrical shape of centralized positioning, and drain outlet portion is divided into slick and sly little arc surface and contacts with sealing mat (6) line in the sealing device, valve seat (8) with nut, packing ring be fixed on water tank (10) the bottom and with overflow pipe (11) threaded connection.
Ball float (4) is connected also and can connects firmly with pin with valve gap (5).
During use, only need pull switch (not pointing out among the figure) gently, drive control lever (2) thereby pull-up valve gap sealing devices such as (5) by action bars (1), water just pours in the sitting toilet rapidly from the outfall of valve seat (8), when the gravity of sealing device during greater than the buoyancy of ball float (4), valve gap (5) etc. just vertically falls back to rapidly under the effect of backstay (9) on the origin-location automatically, and switch resets, and water tank (10) begins water inlet again and constantly repeats above-mentioned circulation.
Be using water wisely, only need just sometimes, will all not put by a water tank water towards low amounts of water.Then you think water towards much of that, just can pull switch more in the opposite direction, control lever (2) is moved down, thereby make sealing device seal the outfall of valve seat (8) rapidly.
The utility model is compared with prior art: because adopting ball float buoyancy and water tank water shutoff pressure and from mutually balanced design of gravity, so sensitivity is very high, as long as external force just can easily realize instantaneous impulse force and quick water shutoff automatically a little. Decapacitation realizes the draining automatic open close, outside quantitatively draining resets, also because control lever, floating ball structure are arranged, only need be as required at any time all can upper and lower operating switch, control arbitrarily displacement and reach water-saving purpose. Because of the sealing device that adopts hard valve gap, sealing gasket, pressure cap to form, just make the sealing gasket energy permanency shape that is clipped in the middle, prolonged service life, locate with fairlead because of the upper end control lever again, lower value seat, sealing device are located with backstay, and upper and lower end all is positioned, is controlled in the same vertical plane, and sealing device contacts for line with discharge outlet, so just guaranteed leakproofness up hill and dale, its leakproof stability can reach more than 99.99%, and is perfectly safe.
