Abstract

The utility model discloses a water saving valve which is suitable for flushing a lavatory. A valve body 3 is provided with a water inlet hole 7, a water charging hole 8, a water discharging hole 9, and a water flushing hole 10. A piston 5 which is connected with a piston rod 11 is arranged in the valve body 3, and a spring 6 is arranged in the valve body on the piston rod 11. The piston rod 11 is connected with a transmission device. When the piston 5 is positioned upwards, the water discharging hole 9 and the water flushing hole 10 are communicated. When the piston 5 is positioned downwards, the water inlet hole 7 and the water charging hole 8 are communicated. The utility model which is opened and is closed through feet has the advantages of accurately and conveniently opening and closing, reducing the labor intensity of a manager, saving water, and keeping the lavatory clean.

Description

Water-saving valve

The utility model has related to a kind of water-saving valve that is suitable for the lavatory flushing water tank.

Thereby the valve that is used in the flushing water closet at present adopts ball valve to rely on more artificially to rotate handle and drives the ball that accent is arranged in the valve body and be communicated with or cut off the water supply; Push-pull valve artificially rotates rotating disk, and the screw of twisting valve body drives flexible the finishing of plate and cuts off the water supply or water flowing; The pressure type valve body relies on the own wt of water that valve is washed open and arrives certain position under water, returns to original position under spring action.The shortcoming that above-mentioned valve exists is: as not closing after the water, alter into the waste at water source, as not opening the valve flushing, easily cause the abominable of lavatory sanitary condition, increase administrative staff and administrative staff's work purport degree, the valve maintenance is inconvenient.

The utility model provides a kind of foot-propelled opening and closing valve that utilizes, and it is accurate, convenient to open and close, and reaches the water-saving valve that promptly cleans the purpose of economizing on water again in careless.

Technical solution of the present utility model is: a kind of water-saving valve, it is characterized in that: valve body 3 is provided with blasthole 7, last water hole 8, drainage hole 9 and bath hole 10, piston 5 is housed in the valve body 3, piston 5 is connected to piston rod 11, in piston rod 11 upper valve bodies 3 spring 6 is housed, and piston rod 11 is connected to transmission device, drainage hole 9 and bath hole 10 are communicated with when piston 5 is upper, and blasthole 7 is communicated with last water hole 8 when piston 5 is the next.

The utility model compared with prior art has: available foot-propelled opens and closes valve, opens and closes accurately, reaches in careless and promptly cleans the purpose of water saving again, and can reduce the labour intensity that administrative staff alleviate administrative staff, advantage easy to maintenance.

Fig. 1 is the utility model embodiment appearance structure schematic diagram;

Fig. 2 is the utility model embodiment piston internal construction schematic diagram when upper;

Fig. 3 is the utility model embodiment piston internal construction schematic diagram when the next.

Below in conjunction with accompanying drawing the utility model embodiment is described further:

As shown in the figure: valve body 3 has the water inlet 7 that inserts water pipe, the last water hole 8 of water receiving case upper hose, the drainage hole 9 of water and the bath hole 10 that connects flush port under the water receiving case, the piston 5 of band waterproof grommet 4 is housed in the valve body 3, interference is equipped with on piston rod 11 piston rods 11 spring 6 is housed on the piston 5, the top of spring 6 is fixed on the piston rod 11, the bottom thread of valve body 3 is connected to valve gap 12 and adds sealing ring, valve gap has with the hole of piston rod 11 interference fits and sealing ring is housed, the drive link 2 of piston rod 11 underneath hinges connection, drive link 2 and foot rest 1 hinge-coupled, for the attractive in appearance and personal safety in ground with drive link 2 and foot rest 1 time below ground surface, foot pedal 1 when with the lavatory, move down at drive link effect lower piston rod 11, spring 6 is compressed, piston 5 moves on to the next, blasthole 7 is communicated with last water hole 8, water is floated automatic cut-out by water after water tank injects certain altitude, no longer go up water, the lavatory is with finishing, pin leaves foot rest 1, piston 5 returns to upper under the effect of spring 6, seal blasthole 7 and last water hole 8 and opened drainage hole 9 and bath hole 10 simultaneously, water toilet flushing in the water tank, the opening and closing of valve are by toilet user's foot-operated finishing in careless like this.Use bakelite in the selection, promptly economize metal can prolong again working life be convenient to the maintenance.
