Abstract
The utility model relates to a water drainage valve of a cistern. A hollow valve body is composed of a flexible rubber membrane and a valve cover. A water drainage port is covered on a limiting device arranged at a setting height. Two holes are arranged on the valve cover. One of the two holes is connected with a compressing cavity through a pipe, and the other hole is connected with a control button through a pipe. When water enters a cistern, the water drainage port is closed by the compressing cavity. When water is drained, compressed gas in the cavity of the valve body is discharged through the control button and the rubber membrane is opened to drain water by water pressure. The utility model has the advantages of double functions of manual operation and automatic operation, branching water drainage by combined use, simple structure, convenient operation, reliable operation and low cost.
Description
Technical field
The present invention relates to a kind of water tank drain valve, but particularly a kind of toilet seat water tank draining valve of flexibility automatic compensation sealing.
Background technology
The existing water tank drain valve in market is plane cushion rubber and hollow glueballs two big classes at present, owing to the narrower flexibility of its working method reason work plane when closing draining valve is poor, can not correct automatically if very little distortion takes place glue spare, therefore bad sealing and the situation of leaking happens occasionally usually causes the waste of water resource.
Summary of the invention
In order to overcome the deficiency that existing water valve leaks, the invention provides a kind of simple in structurely, cost is low, but the draining valve of the automatic compensation sealing of a kind of flexibility easy to use is specially adapted to the draining valve of toilet seat water tank.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: described draining valve comprises outfall, fixed connection spare, bleed off pipe, it is characterized in that, valve body is the dish shape, is fixedly arranged in the valve body that a closed hollow is formed in circular valve gap lower edge by the middle part of flexibility to the dish shape glued membrane of lower process.One balance pipe is arranged at valve gap top, by the equalizing main gas compression chamber suitable for reading binding other with placing valve body.During the water tank retaining, the water surface rises, and occluded air compression chamber end opening forces the compression intracavity gas to enter in the valve body chamber through equalizing main, valve gap balance pipe, and the extraneous hydraulic pressure of balance forces valve primer film to be close to the sealing mouth of a river, outfall upper edge on the other hand on the one hand.Valve body is topped on outfall, is fixedly arranged on the height of stopping means setting.The valve gap top also is provided with a relief hole, is connected with gauge tap through relief pipeline.Only need press gauge tap during draining, release the Compressed Gas in the valve body, and be communicated with atmosphere and make and be atmospheric pressure in valve body the chamber in, the pressure of the interior retaining of water tank will be raised the outfall glued membrane and go out the mouth of a river.
Compared with prior art, the present invention utilizes the atmospheric water pressure reduction sealing of flexible membrane top and bottom tighter, opens faster.Simple in structure, can be manual, also can be automatic, use also capable of being combined reaches stepping bath purpose, and cost is low very easily to be promoted.

The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
Among Fig. 1, described draining valve, during manual work, outfall, stopping means, glued membrane, valve gap sequence interlock; The gas compression chamber is the positive displacement structure, and the no end, the cross section can be any geometric figure, is fixedly arranged in by the valve body; Balance pipe, balance pipe, compression chamber links successively; Control knob, relief tube, relief hole links successively.When water tank was not intake, the compression chamber end opening was higher than the initial water surface, the flexible glued membrane free-falling of valve body, the bottom of projection is covered on the outfall, control knob is normally closed, in the valve body chamber through balance pipe, balance pipe, compression chamber communicates with atmosphere; During the water inlet beginning, the water surface rises in the water tank, but when also being not enough to overcome the glued membrane deadweight, sealed buoyancy the compression chamber end opening, rising along with the water surface, compressed chamber in the valve body chamber, balance pipe, balance pipe all the time with water tank in retaining pressure keep balance, because glued membrane is covered in outfall, bottom, the mouth of a river is an atmosphere, and top has only a downward level pressure, therefore only can be tighter with the rising elimination glued membrane and the outfall clearance seal of water level in the water tank, this power is that the pressured gas transfer that contracts is finished, and condition has been created in the control of accommodating; Do not enter the unlatching that influences valve in the valve body chamber in order to ensure water, balance pipe should be n shape and link, and tube wall should definitely be higher than the water tank peak level under the transverse tube part highest point.
During draining, only need normally closed control knob unlatching to be released the interior Compressed Gas of valve body and communicate, make and keep atmospheric pressure in the valve pocket with atmosphere, glued membrane rising opening water discharge mouth under hydraulic pressure, beginning draining, draining are finished the interior water surface of rear water box and are got back to initial water inlet state again, go round and begin again.
Among Fig. 2, described draining valve when working automatically, can place automatic control switch the optional position of relief hole through the relief tube atmosphere entry, and the relief tube end is fixed on the overflow tube wall.Automatic switch can be used various ways, and is pneumatic as lever actuated, and hydrodynamic(al) is electronic etc., and remaining structure is consistent during with course of action and manual work, no longer repeats.
Draining valve of the present invention is convenient and installs that outfall lower end dowel soffit has a columnar protrusions,, supports and can not rotate fixedly during sole bar reinforcement with connecting bolt.
The present invention seals reliably, can be manual, can be automatic, and also can be used in combination and reach stepping draining purpose, it is simple in structure, and cost is low, and reliable operation is easy to operate, has high promotional value.
