Description

Selt-stop water-saving valve for stopping water

The utility model belongs to the technical field of valve valve.

At present a lot of places are serious water shortage all, and water tap is often cut off the water, and one of the reason of cutting off the water is the measure of having taked Timing water supply in order to guarantee supply; Former two is that hydraulic pressure causes that to be in high-rise tap water anhydrous sometimes when not enough therefore.Our ordinary faucet used in everyday and common valve only possess simple open and close function.After cutting off the water, forget sometimes and turn off the tap, when coming water once more, will cause in a large number like this and metal run out that especially at midnight during water, water can overflow to room and stair.So not only waste a large amount of water, return life and make troubles.

The purpose of this utility model is a kind of valve of design, and it can close after cutting off the water at every turn automatically, makes the waste that can not cause water when coming water once more, and when the tap water normal supply, it can guarantee that tap water pipe line is unimpeded always; No matter this valve can also accomplish that when, a very important person need close it and just can close at any time.

The utility model is to realize like this.

It includes a valve body, spool is housed in the valve body, rubber washer is housed on the spool, in valve body lower portion, packing ring and screw plug are housed, between screw plug and the spool spring is housed, push rod is equipped with on spool top, have an appointment on the push rod 10 ° to 45 ° skewed slot, another groove on the push rod is equipped with seal ring, and button is equipped with at the push rod top; A transverse holes is arranged in the valve body, piston is housed in the hole, groove on the piston is equipped with seal ring, there is a facet piston rod end of piston, also have a little inclined-plane consistent with the push rod angle of bevel, the other end of piston has one section little garden post, and the piston left part is equipped with spring and stop pin, the outside seal of transverse holes is connected with screw plug and packing ring, and an aperture that communicates with the water-inlet cavity of valve body from the piston right-hand member is arranged on the valve body; On valve body, the left position of piston has a screw that communicates with transverse holes, and awl-end screw is housed in the screw.

Effect of the present utility model: it can replace the total valve before each family's water meter, also can control one or a string water tap with it, after cutting off the water at every turn, its energy automatic closing, make like this when coming water once more, be unlikely because of forgetting to turn off the tap and cause the phenomenon of metalling run out, exempted the waste of the water that causes because of not turning off the tap the back that cuts off the water fully.Because it has a plurality of water taps of valve may command, to use and after public washing room, canteen sink etc. is often cut off the water, easily forget the occasion of turning off the tap, water-saving result is fairly obvious.In addition,, replace to close it at any time after the total valve, so that by the tap water pipe line of dress, maintenance back with it because it can close when the people needs at any time.

That accompanying drawing 1 is represented is structural principle of the present utility model and embodiment.(1) is the garden chapiter screw among the figure, (2) be packing ring, (3) are buttons, and (4) are O shape rubber seal, (5) be stop pin, (6) be piston, (7) are screw plugs, and (8) are springs, (9) be O shape rubber seal, (10) be push rod, (11) are nuts, and (12) are packing rings, (13) be rubber washer, (14) be spring, (15) are spools, and (16) are packing rings, (17) be screw plug, (18) be valve body, (27) are packing rings, and (28) are awl-end screws.Screw (1) and packing ring (2) are used for button (3) is fastened on push rod (10), and nut (11) and packing ring (12) are used for rubber washer (13) is fastened with spool (15).Can not botch routines in order to guarantee the utility model because of getting rusty, it uses the rubber asbestos except packing ring (16), (27), rubber is used in rubber washer (13), O type rubber seal (4), (9), outside the available plastics of button (3), other all other parts all use copper, stainless steel or plastics to make.

Working principle of the present utility model is as follows:

During use, the inlet on its right should tap into water pipe, and the outlet on the left side picks out water pipe.Fig. 1 represents it is valve closed condition, and at this moment water flows into water-inlet cavity (22) inflow chamber (20) again and since spool (15), rubber washer (13) stop that water can not arrive chamber (19), so valve is in closed condition.When needing water, press down with handgrip button (3), push rod (10) moves downward, compressed spring (14), promotion spool (15), nut (11), packing ring (12), rubber washer (13) move downward, make valve open, through chamber (20), chamber (21), arrival chamber (19), the water-stopping self-closing water-saving valve is in logical state to water by water-inlet cavity (22); In addition, because water-inlet cavity (22) communicates with transverse holes (26) through small holes (23), the pressure of water passes to transverse holes (26) right-hand member, promotes piston (6) pressure spring (8) to left movement.There is a facet (24) piston rod end of piston (6), also have one with the consistent little inclined-plane of push rod (10) angle of bevel.The angle of bevel of push rod in the present embodiment (10) is 15 °.After depressing push rod (10), piston (6) is to left movement, and facet (24) will block 15 ° skewed slot (25) of push rod (10), and push rod (10) can't move upward, and valve just is in logical state always.After cutting off the water, because transverse holes (26) right-hand member loses hydraulic pressure, piston (6) moves right under the effect of spring (8), no longer block 15 ° skewed slot (25) of push rod (10), spring (14) just promotes spool (15) and moves upward together with push rod (10), and valve is just closed automatically.Run into and unmanned on the scenely come water to become once more can not wasted water.It is to be used for the stroke that limited piston (6) is moved back to the right that piston in this example (6) right-hand member has a little garden post, it is moved back to the right can not stop up afterwards aperture (23).General family is connected on the total valve before the water meter, is at ordinary times not to be with to need to close, and only closes to get final product when installation pipeline or maintenance.The utility model if with screw-driver awl-end screw (28) to backspin, just can force piston (6) to move right, like this, the facet (24) of the tailpiece of the piston rod of piston (6) has withdrawed from 15 ° of skewed slots (25) of push rod (10), valve can be closed under spring (14) and hydraulic pressure acting in conjunction immediately.With screw-driver awl-end screw (28) is upwards revolved after fixing pipeline, this valve recovers normal working again.

It should be noted: spring (14) can make under the prerequisite that spool (15), push rod (10) etc. upwards reset satisfying, and elastic force smaller as far as possible; Spring (8) also answers elastic force as far as possible little as long as can make the piston rod end facet (24) of piston (6) withdraw from the skewed slot (25) of push rod (10).In the present embodiment, valve inlet and outlet all are 3/4 " pipe thread, as will being connected in other diameter pipeline, but the adjunction reduction nipple.The spring of present embodiment (14) is to be compressed to that pressure is 0.4 kilogram behind the valve open, spring (8) piston (6) block push rod (10) afterwards pressure be 0.2 kilogram, piston (6) diameter is 22 millimeters.In this example, when water level dropped to dried up tap always and has only one meter, hydraulic pressure had 0.1 kg/cm.Water is to directed force F left=0.25 * 3.14 * 2.2 * 2.2 * 0.1=0.38 kilogram＞0.2 of piston (6) kilogram.So just guaranteed not can be in water supply pressure decline process throttle down too early.

Accompanying drawing 2 expressions are to use the example that the utility model goes to control a string water tap water saving.Here (29) are water pipes, and (30) are water taps, and (31) are water meters, and (32) are the assemblies of this water-stopping self-closing water-saving valve.
