Abstract
The utility model relates to a time-delay self-closing valve for saving water, which is composed of a ripple pipe damping cavity and a check valve with micro-flow holes assembling into an elastic sealing whole so as to replace a sealing whole of comparatively complex time-delay flushing valve. When the time-delay self-closing valve for saving water is used, a valve rod is pressed so as to flush a toilet; water quantity is controlled by controlling the compression stroke of the ripple pipe, which plays a role in time-delay and self-closing. The utility model is suitable for washing sanitary water-supply installations in various public places such as car, boat, toilet, etc.
Description
The utility model delay self-closing water-saving valve belongs to the improvement of valve.
Now public place such as lavatory, train, steamer etc. are washed one's hands and mostly are common water valve or handle, pressure handle water valve with water tap, and are very inconvenient when washing one's hands, and wash perhaps that hand lingering fear handle is made dirty and shutoff valve not, cause water waste.It is flashing valve that Chinese patent 86208288 provides a kind of cavity type time-delay, it is by rubber (plastics) or metal corrugated Seal cage obturator ring and go up the elastic packing integral body that sleeve pipe is formed, the piston and the cavity that have replaced traditional flashing valve, the bath time-delay is regulated by regulating ring.This valve has been very big improvement.The purpose of this utility model provides a kind of public place that is exclusively used in and washes one's hands and use water valve, this water valve is formed elastic packing integral body by the one-way valve of corrugated Seal cage and band micropore, utilize the resiliently deformable of corrugated Seal cage to make the valve delay-self-closing, the guiding devices such as sleeve pipe in the above-mentioned flashing valve have been cancelled, structure is more simple, can play effect easy to use and water saving.
The utility model structure is such, with reference to accompanying drawing, its valve body (1) is with general water valve valve-body, in valve pocket, there is a lower end to have the bellows damping cavity (5) of spool (7), damping cavity upper end be positioned at the valve rod as switch (2) that its top, valve body top has valve gap (3) and contact, there is a center hole (8) lower end of valve rod (2), the one-way valve (4) in a band miniflow hole (12) is installed in the center hole, a spring (11) is arranged in the one-way valve, one-way valve radial position at valve rod has a water inlet and outlet through hole (14), one boss (15) is arranged on the valve rod cylindrical of through hole lower end, this cylindrical boss is plane contact with the gland nut (6) that is used for fixing valve rod, valve rod cylindrical boss lower end is adopted to be threaded or to peg graft with corrugated damping cavity upper end and all can, gland nut (6) valve body (1) adopts and is threaded, touching mother (9) with seal ring (13) and sealing between gland nut (6) upper end and valve rod (2) seals, spool (7) adopts rubber to make, and is connected with bellows with the method for plant propagation with cutting.One-way valve when the valve closing state is because its spring action and bellows are formed a sealing integral body by compression, press valve rod, bellows by compression, the bellows internal pressure increases, and makes one-way valve opens, leaked water damping cavity internal pressure in the damping cavity descends, current promote to move on the spool, and valve open is when the damping cavity internal pressure equates with the chamber pressure outside, the damping cavity returning position, valve closing.
Accompanying drawing is a delay self-closing water-saving valve closed condition structural drawing.
In the damping cavity of bellows (5) because the miniflow hole (12) on the one-way valve (4) is interlinked to the outside with Seal cage, the damping cavity internal water pressure equates with waterexit end (10) pipeline internal water pressure, one-way valve (4) contacts closely with valve rod center hole (8) owing to the effect of spring (11) one-way valve (4) is closed, and the elastic force of bellows (5) is ended spool (7) effectively.During valve gap (3) on pressing valve rod (2), valve rod (2) moves down, the damping cavity internal pressure increases, one-way valve (4) is opened, water releases by bellows (5) top valve rod center hole (8) and valve rod warp-wise water inlet and outlet through hole in the damping cavity, bellows (5) is compressed simultaneously, after stopping to press valve gap, because the effect of the elastic restoring force of bellows (5) makes bellows damping cavity internal water pressure be lower than the interior water pressure of waterexit end (10) pipeline, one-way valve (4) is owing to contained spring (11) effect is closed, water slowly enters in the damping cavity by the miniflow hole (12) of one-way valve (4), this moment because bellows (5) also is in compressive state.The power that spool (7) is ended can not be provided, the pressure of water promotion spool (7) moves upward in the feed-water end pipeline, the compression area of the whole valve pocket water inlet of valve open back valve core lower end surface is still greater than the upper-end surface, and spool (7) continues to move upward and opens fully until valve.
Along with water enters in the damping cavity from miniflow hole (12), bellows (5) extends gradually by the elastic restoring force of itself, ends fully until spool (7).The speed and the water of bellows (5) elongation are linear by the flow velocity that miniflow hole (12) enter damping cavity.Played the effect of delay-self-closing.
Adjust the size in one-way valve miniflow hole (12), just can adjust the time of delay-self-closing, in case make product, want to change delay time, just can solve by the compression stroke of regulating bellows, thereby adjusting the water yield, also is that valve rod moves down and goes through evil more, and the big water-outlet quantity of bellows compression stroke is just big.
According to different fields of employment, the chromium plating of valve body available copper, copper, cast steel are made, and bellows adopts non-ferrous metal or stainless steel to make, and valve rod, gland, sealing nut, miniflow hole one-way valve are copper, and seal ring and spring be selection routinely all.
The utility model thrift lock is compared with existing water valve, and is simple in structure, do not have to impact, and noiselessness, easy to install, the supply equipment such as be particularly useful as washing that each public place such as army, office, school, station, harbour, car, ship etc. locate, wash one's hands.
Claims (1)
1, a kind of delay self-closing water-saving valve, it is to have the valve rod (2) that valve gap (3) lower end has center hole (8) and cylindrical boss (15) by valve body (1), its top of being positioned at valve body top, what be used for fixing stem position adopts the gland nut (6) that is threaded with valve body top, and seal ring (13) sealing nut (9) that seals between valve rod and the gland nut and the bellows parts such as (5) that are positioned at valve pocket are formed.The utility model is characterised in that its control opens and closes partly, and the thick Buddhist nun of the bellows chamber (5) that has spool (7) by the one-way valve (4) and the lower end in the band miniflow hole (12) that is positioned at valve rod lower end center hole (8) is assembled into elastic packing integral body.
