CN2791128Y - Water-flushing valve of toilet closet - Google Patents

Abstract

The utility model relates to a water flushing valve of a toilet bowl, which belongs to a time-delay automatic closing valve. The utility model comprises an inner part and an outer part, wherein the outer part is provided with a valve casing, a pressure spring and a screw nut which is used for adjusting and prolonging time. The inner part is provided with a left time-delay water tank, a piston, a fence frame, a right time-delay water tank and a sealing ring. A piston rod is a connecting assembly of the inner and the outer parts. When a user push off the valve of the utility model, the valve can be closed by the back pressure of the pressure spring. The water can slowly enter the gap between the left time-delay water tank and the sealing ring on the piston at the same time when the valve is closed, and the water can be slowly squeezed out from the gap between the right time-delay water tank and the sealing ring on the piston, so as to achieve the purpose of prolonging time. The screw nut for adjusting and prolonging time can be adjusted to a good position to control water flushing time, so as to adapt to toilet bowls in various styles. The water pressure of the water which comes out from a water pipe is larger than the water pressure of the water which comes out from the water tanks, so the toilet bowl is easy to flush cleanly.

Description

The flush toilet flushing valve

Affiliated technical field

The utility model relates to a kind of flush toilet flushing valve, belongs to automatic delay function formula valve.

Background technology

At present, known common flush toilet generally all has a little water tank, and the water that often occurs with little water tank when using flush toilet once is towards sordid, needs to dash repeatedly, has so just wasted water resource and user's time.Improper again with common valve, reason is that the low amounts of water under the flush toilet is difficult to control.

Summary of the invention

Once dash clean and uncommon valve and be difficult to control low amounts of water under the flush toilet in order to overcome the common little water tank of flush toilet band, the utility model provides a kind of flush toilet flushing valve, it can be rinsed well, but also it is just right to control under the flush toilet position of low amounts of water.

The technical scheme that its technical problem that solves the utility model adopts is: the valve composition that consists of inside and outside two parts, the outside has nut and the stage clip of the adjusting time expand on copper shell, piston rod, the piston rod to combine, inside be with piston rod be a core, linking on the piston rod piston, left side time-delay water tank be attached on the copper shell, the right time-delay water tank is to combine at fence frame and copper shell.When the people pushed valve open, just the people pushed away piston rod inward, owing to linking piston on the piston rod, simultaneously, piston had been advanced left side time-delay water tank, had also just moved the position of piston in the right time-delay water tank.When staff leaves valve, the counter-pressure of stage clip meeting valve-off, in valve-off, the piston in the time-delay water tank on the left side and the right can be moved toward original locality; At this moment, the space between the sealing ring on left side time-delay water tank and the piston can enter water at leisure, and the space between the sealing ring on the right time-delay water tank and the piston can push water outlet at leisure.The time of like this having utilized this operating principle to prolong valve-off achieves the goal.Certainly when implementing the utility model, also can be made into the valve of single time-delay water tank, have only left side time-delay water tank or the right time-delay water tank.The utility model is the utility model patent number in my application: the ZL94217133.0 title: increase a time-delay water tank on the basis of " water tap " and regulate the nut of time expand, because the flush toilet of each style is in different size, in order to control the time of washing by water well, waste water resource not, by the nut of regulating time expand, can regulate the position, control the time of bath, adapt to the flush toilet of every kind of style.Because big many of the hydraulic pressure that the hydraulic pressure that comes out from water pipe comes out than water tank also just are easy to flush toilet is rinsed well.Also have a bit extremely important be the size of flush toilet flushing valve and the water pipe internal diameter that connect greater than 25 millimeters, not so the size of water pipe internal diameter is too little is difficult to rinse well flush toilet.

The beneficial effects of the utility model are, have overcome common flush toilet and have once dashed clean and be difficult to the position of the beneath small amount of water of control flush toilet with common valve, bring convenience and using water wisely to the user.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the insight structural map of an embodiment of the present utility model.

Among the figure 1, the copper shell, 2, left side time-delay water tank, 3, sealing ring, 4, sealing ring, 5, sealing ring, 6, stage clip, 7, regulate the nut of time expand, 8, piston rod, 9, piston, 10, sealing ring, 11, (the fence frame here divides left and right sides two parts to the fence frame, and left-hand component is that part hollows out and right-hand component is not hollow out; Purpose is to make the right time-delay water tank for right-hand component is water-tight.), 12, sealing ring, 13, sealing ring, 15, the right time-delay water tank.

The specific embodiment

In the embodiment shown in fig. 1, when people's push piston bar (8), stage clip (6) is compressed, piston (9) is pushed among the left side time-delay water tank (2), the right time-delay water tank (15) enters water between the space, at this moment valve is opened, and water comes in to rush out by fence frame (11) from water inlet, and the left side of fence frame (11) half part can be complete by water, right-hand component as fence.When staff leaves piston rod (8), the counter-pressure of stage clip (6) piston (9) toward pulling back, at this moment the resistance of the time-delay water tank on the left side and the right hauls piston, and the time-delay water tank on the left side pushes water outlet from the time-delay water tank that enters water, the right between the space between the space, at leisure valve-off.When the people regulates the nut (7) of time-delay water tank, just regulate the water yield of going out.

Claims (2)

1. flush toilet flushing valve, it is characterized in that: the valve composition that consists of inside and outside two parts, the outside has nut (7) and the stage clip (6) of the adjusting time expand on copper shell (1), piston rod (8), the piston rod (8) to combine, inside be with piston rod (8) serve as an axle core, to link piston (9), left side time-delay water tank (2) on piston rod (8) be to be attached at that copper shell (1) is gone up, the right time-delay water tank (15) is to combine at fence frame (11) and copper shell (1).

2. flush toilet flushing valve according to claim 1 is characterized in that: the size of flush toilet flushing valve and the water pipe internal diameter that is connect is greater than 25 millimeters.
