Abstract
The utility model relates to a pedal type hydraulic control flushing valve, which comprises a hydraulic chamber consisting of a pressure relief valve rod, a sealing pad, a valve core and the like, and controls the valve core to be closed, wherein the pressure relief valve rod is pressed down, water in the hydraulic chamber is discharged from holes on the pressure relief valve rod, thereby the valve core is opened, and the flushing valve is opened, when disentwining a key of the pressure relief valve rod, a spring under the pressure relief valve rod helps the pressure relief valve rod to reset, holes on the pressure relief valve rod are closed again, pressure in the hydraulic chamber is formed again, and the flushing valve is closed. When a hand or a foot acts on the key of the pressure relief valve rod randomly, the valve can be easily opened, the flushing valve is proved to have obvious water-saving effect through multiple tests, practical use and long service life, when being installed under the ground surface, the flushing valve is beautiful and elegant, and the pedaling control is sanitary and convenient.
Description
Technical field
The utility model belongs to a kind of foot-operated hydraulic control flushing valve of use in toilet.
Technical background
The seepy question of wc flushing cistern has become a long-term puzzlement people's a difficult problem, has pass department and introduces, and the water yield that China loses because of radiator leak every year reaches about 6 billion cubic meters.In order to prevent radiator leak, the someone has invented fluid pressure type control flushing valve.Known fluid pressure type control flushing valve mainly is made up of spool, main body, control device and back-moving spring is formed, and the top of valve is handle or button, when needing flushing, uses and defeats handle or button and release hydraulic pressure on the spool, thereby allow the spool unlatching.Though this method can prevent that water valve from leaking, but also bring certain difficulty to use, up to the present, no matter be manually or all there is following weakness in the flushing valve of fluid pressure type control: manually opened inconvenience, be unfavorable for water saving, the complex structure volume is big, is inconvenient to bury the ground concealed installation, keeps away the cross-infection that unavoidable hand contact flushing valve brings.
The utility model content
The purpose of this utility model just provides a kind of leakproof, and is simple in structure, fault is few, can be arbitrarily with the foot-operated and manually water-saving flushing valve of control.Another object of the present invention is to satisfy the hygienic requirements of the foot-operated control of flushing between public places sanitary, the cross-infection of avoiding hand contact flushing valve to bring.
The purpose of this utility model is achieved in that the pressure release valve rod with existing hydraulic control flushing valve changes into foot-operated, and on the pressure release valve rod, be provided with rim of a cup and relief hole, the termination of relief hole is located in the rim of a cup 11, when when pressing down the relief valve bar, water in the valve body is rim of a cup and relief hole discharge on the pressure release valve rod, thereby opens spool; When spring 8 upwards pushed away the pressure release valve rod, the sealed pad of the rim of a cup of pressure release valve rod covered, and the relief hole in the pressure release valve rod also is closed, form a confined space at pressure release valve rod, valve body, valve core chamber, water enters behind the confined space because the pressure effect, and it is downward to promote spool, closes flushing valve.
The utility model is through test of many times and actual the use, and not only proof has tangible water-saving result, and long service life, is installed in underground, and elegant in appearance, and foot-operated control is that health is convenient again, for daily life has been brought more convenience.
The description of drawings specific embodiment
Accompanying drawing 2 is foot-operated hydraulic control flushing valve generalized sections when opening.
As shown in Figure 1, foot-operated hydraulic control flushing valve is combined into by stepping on handle 1, pressure release valve rod 2, rim of a cup 11, valve gap 3, sealing mat 4, valve seals 5, spool 6, valve rod V-shaped seal ring 7, spring 8, valve body 9 etc.; Step on handle 1 and be fixed on release valve rod 2 tops, step on handle 1 and the 2 energy linkages from top to bottom of pressure release valve rod; The rim of a cup 11 of pressure release valve rod 2 combines as a whole with pressure release valve rod 2, relief hole 10 the termination be located in the rim of a cup 11; When spring 8 upwards pushes away pressure release valve rod 2, the rim of a cup 11 sealed pads 4 of pressure release valve rod 2 cover, relief hole 10 on the pressure release valve rod 2 also is closed, at pressure release valve rod 2, sealing mat 4, valve seals 5, spool 6 and valve rod V-shaped seal ring 7, confined space of formation, water enters behind the confined space because the pressure effect, it is downward to promote spool 6, closes flushing valve.
As shown in Figure 2, depress flushing valve and step on handle 1, the rim of a cup 11 of pressure release valve rod 2 leaves sealing mat 4, water in the confined space is discharged through the rim of a cup on the pressure release valve rod 2 11 enters relief hole 10 after, and spool 6 moves up under the effect of hydraulic pressure, the unlatching flushing valve. when unclamp step on handle 1 after, under the effect of spring 8, pressure release valve rod 2 moves upward, and the sealed once more pad 4 of rim of a cup 11 covers, and flushing valve is closed automatically.
Through test of many times and the actual proof of using, the utility model adopts pressure release valve rod 2 and 7 combinations of valve rod V-shaped seal ring after improving, and is not only more simple in structure than the conventional flush valves, and reliable operation, and prolong application life greatly.
