Abstract
The utility model relates to a water valve which is automatically closed in set time and can be arranged in a water faucet or other water apparatus to have the function of closing in set time. A plunger piston (21) is pressed on a centre hole (16) of a base by the pressure of a pressure chamber (9) when the water valve in a closed position. When a button (2) and a pilot valve (4) are opened, the pressure of the pressure chamber is released, the plunger piston rises to contact with a top cap (5) under the action of the water pressure, and meanwhile, the water valve is opened, and a large quantity of water flows out from a water outlet, a little water flows into the pressure chamber through a damping pore; when the button is unloosened, the pilot valve is closed, and the plunger piston drops down. When the base is tightly pressed by the plunger piston, the water valve is closed, the top cap is higher, the stroke of the plunger piston is increased, the opening time of the water valve is prolonged, and contrarily, the opening time of the water valve is shortened.
Description
The utility model relates to a kind of water valve that can close automatically in set time.
The place that need frequently wash one's hands in public lavatory, hospital etc., for using water wisely with prevent cross infection, hope can have a kind of water nozzle that just can close automatically without the hand contact.In order to address that need, invented abroad that communique clear 58---51097 is described as Japan special permission, the water nozzle that can in set time, close automatically.This water nozzle is to come set time by the area that changes damping hole, and the method for this set time has been brought following problems.
(1) to realize the adjusting of damping hole area, four, five parts in addition that precision is higher will be arranged at least.
(2) part of damping hole must adopt elastic material, so easy obstruction.
(3) the time set part is located in two chambeies with cylinder body, piston portion branch, has increased volume, has increased the inner passage.
Owing to above reason, the structure of this water nozzle is comparatively complicated, makes also difficulty.
The purpose of this utility model provides the water valve that a kind of structure is more simple, can close automatically in set time.This valve can be contained in water nozzle or other water appliance, makes them have the function of regularly closing.
The water valve water intake communicates with delivery (pipe) line, and the water in the pipeline enters in the valve from water intake, flows out from water outlet through the path that connects water intake and water outlet.An energy mobile plunger in cylinder body can be blocked this path closes water valve.The upper-end surface of plunger and cylinder body and other pieces are formed a pressure chamber, pressure chamber communicates with water intake by a tiny path, a manual pilot valve, when it is closed, the pressure of delivery (pipe) line acts on the upper-end surface of plunger through water intake and above-mentioned tiny path and pressure chamber, make plunger block path between water intake and the water outlet, water valve cuts out.When manual pilot valve is opened, promptly shed the pressure of pressure chamber, so plunger moves up the path conducting between water intake and the water outlet, water valve unlatching under the effect of the delivery (pipe) line pressure that acts on its lower end surface.When closing again after manual pilot valve is opened, Shui Fa And does not close at once, at this moment, through the water that aforementioned tiny path enters pressure chamber plunger is slowly moved down from water intake, blocks path between water intake and the water outlet once more until plunger.Begin to move up from the pilot valve opening plunger, close to pilot valve, plunger moves down, and a period of time of blocking the path between water intake and the water outlet at last is exactly the opening time of water valve.After pilot valve is closed, the opening time of water valve is by the length of aforementioned tiny path and the sectional area size of this path, and the decision of the stroke of plunger, of the present utility modelly is characterised in that the opening time of regulating water valve by the stroke of pilot plunger.When pilot valve was opened, plunger moved to till certain block piece of contact under the effect of delivery (pipe) line pressure, as long as regulate the position of this block piece, stroke that just can pilot plunger.As long as for example top cover can be made can upper and lower adjusting, and plunger moves to till the contact top cover, like this stroke that the position of adjusting top cover just can pilot plunger.Also can make top cover nonadjustable, and on top cover, adorn one can upper and lower adjusting adjustable lever, as long as plunger moves to till the contact adjustable lever, like this stroke that the position of adjusting adjustable lever just can pilot plunger.
For easy and simple to handle, pilot valve can be made push button, and pilot valve is opened when promptly pressing with hand, and hand is decontroled pilot valve and just closed.Certainly, consider different purposes, pilot valve also can be made other form.For the pilot valve of push button, can add a locking device sometimes, open the position that can lock it in out behind the pilot valve, to satisfy the needs of long-time water.
In order to make plunger positively block path between water intake and water outlet, can also in the aforementioned pressure chamber, add shock mount, the upper-end surface of plunger is imposed certain pressure.
Sometimes owing to the not high cause of machining accuracy, deflection might take place in plunger when mobile, for fear of this situation, can make plunger have an elongated protrusion along its movement direction, and this projection and the cooperation of certain face play the guiding role.
In order to reduce the friction factor between plunger and cylinder body, make plunger have good sliding capability, can install a sliding sleeve of making by self lubricating material at the position that cylinder body cooperates with plunger additional, in this occasion, teflon is a kind of good material.
In the relatively poor area of some water quality, damping hole is easily stopped up by the impurity in the water, at this moment can make the water that enters water intake enter damping hole again after by a filter screen.
Figure the-1st, the regularly water nozzle of closing function that has according to the utility model proposes describes its details and working condition below in detail.
Water valve described in the utility model, be contained in the water nozzle body (23), pipe thread (15) joins with delivery (pipe) line, plunger (21) can be in cylinder body (22) on, lower slider, in order to make the sealing between cylinder body (22) and plunger (21) better, " O " shape seal ring (20) is housed in the groove of plunger (21), having damping hole (19) on the plunger (21) connects water inlet (17) and pressure chamber (9), surface friction drag is littler when plunger (21) is slided in cylinder body (22), has inlayed a sliding sleeve of being made by the self lubricating material teflon (11) in cylinder body (22).The projection of plunger lower end surface (14) play the guiding role, and its shape is two (not shown)s of mill off on Cylinder, it and be positioned at guide pin bushing (12) on the centre hole of base (16) and make plunger (21) deflection not when mobile together.When the inclined-plane of plunger (21) lower end surface compressed centre hole of base (16) edge, the path that can cut off between water intake (17) and the water outlet (13) was closed water valve.In order to improve the sealability of valve, elastomer seal (18) is housed in guide pin bushing (12) top of centre hole of base (16).In order to increase the impacting force of plunger (21), in pressure chamber (9), be provided with spring (10).The pilot valve (4) of one head flare is housed in the center hole of top cover (5), after openhanded opening, can be returned to closed position, in chamber (3), be provided with spring (6) in order to make pilot valve (4).Chamber (3) and the exhalant canal of water nozzle are connected in overflow aperture (7), (8).Button (2) have the skewback (1) that has locking effect at ordinary times pilot valve (4) be in closed condition.Because pressure chamber (9) communicates with water intake (17) by damping hole (19), so the pressure of delivery (pipe) line acts on the upper-end surface of plunger (21).At this moment plunger (21) is though the part of lower end surface also is subjected to the pressure of delivery (pipe) line, but because the compression area of upper-end surface is greater than the compression area of lower end surface, therefore downforce is greater than last thrust, plunger (21) just is being pressed under spring force and the upper and lower action of pressure on the centre hole of base (16), path between water intake and water outlet is cut off, and water valve cuts out.
When press the button (2) with hand, pilot valve (4) is when opening, and pressure chamber (9) is connected with the exhalant canal of water nozzle by chamber (3), overflow aperture (7), (8), and the pressure in the pressure chamber (9) discharges.At this moment the lower end surface of plunger (21) still is subjected to the pressure of delivery (pipe) line, till the effect lower plunger (21) of this pressure is moved upwards up to contact top cover (5).The water major part portion that flows into water intake (17) from delivery (pipe) line flows out from water outlet (13) through centre hole of base (16), and minimum part flows out through damping hole (19) pressure chamber (9), chamber (3), overflow hole (7), (8).
When hand was decontroled, pilot valve was closed under the effect of chamber (3) inner spring (6).More and more from the water that damping hole (19) enters, plunger (21) is descended gradually, water intake (17) and water outlet (13) still are conducting in plunger (21) decline process, when plunger (21) is pressed on the centre hole of base (16) at last, pressure chamber has been full of water in (9), at this moment water no longer enters pressure chamber (9) from damping hole (19), and the upper-end surface of plunger (21) and the pressure of lower end surface equate.
If water valve is often left, rotate an angle as long as press the button (2) back with hand, skewback (1) locking is at this moment often opened pilot valve (4).As previously mentioned, pilot valve (4) is often opened the state that will plunger (21) is in out always.
The time that water valve is opened be from press pilot valve (4) plunger (21) move up begin to close pilot valve (4) plunger (21) slowly move down compress centre hole of base (16) till.When pilot valve (4) is opened, the distance that plunger (21) moves up is exactly the water displacement of plunger (21) with the product of its sectional area, also is to begin to be moved down into from plunger (21) to compress this section of centre hole of base (16) and need the water yield of replenishing to pressure chamber (9) by damping hole (19) in the period.This shows the time of water valve unlatching and aperture, the length of damping hole (19), the stroke of the pressure of delivery (pipe) line and plunger (21) is relevant.The utility model is regulated the water valve open-interval by the stroke of pilot plunger (21) exactly.Top cover (5) can be along the upper and lower adjusting of cylinder body (22), and when top cover (5) timing down, the stroke of plunger (21) will shorten when pilot valve (4) is opened, and the water valve opening time shortens.Otherwise when top cover (5) timing upwards, the stroke of plunger (21) just will increase when pilot valve (4) is opened, the growth of water valve opening time.
As mentioned above, the utility model compared with prior art has simple in structure, reliable in action Characteristics ， And has and often opens function. The water nozzle of water valve described in the utility model is housed, can play significant water-saving result as being used for the places such as toilet, lavatory, as use it for hospital, can prevent that then this water valve can also be contained in and make them have the function of regularly cutting out in other water appliance owing to close the cross infection that water nozzle causes with hand.
