Description

Water saving intervening valve

Technical field

The present invention relates to a kind of water saving device, specifically one can not turn off the tap after cutting off the water supply or other with water devices time, can automatically close when water, cut off water route to realize water-saving water saving fixtures.

Background technique

The waste of society water resources remains an inevitable problem, such as, often have to cut off the water in life and but forget to turn off the tap, by the time cause the wasting phenomena of great lot of water resources during water.Therefore, we need the water saving fixtures with following feature: 1, can conveniently add this device under the prerequisite not changing existing water facilities, realize water saving object; 2, there is certain degree of intelligence, independently can realize water-saving function, but not only play prompting or alarm function; 3, cheap, have very strong application value, cost of production, replacing, maintenance expenses must meet ordinary family daily expenditure level.Try not to use electronic equipment, increase the complexity of system, cause the raising of general expenses.

For solving this problem of waste, society has occurred some invent manufacture accordingly, but they can not be both and meet above feature.As patent of invention 201310504972.X discloses a kind of water saving fixtures, its water saving fixtures are a kind of water taps with using water wisely prompt facility, this device utilizes sensor, integrated chip and Led display screen to point out the change of water consumption, to strengthen the water saving consciousness of people, thus reach water saving object.Although this invention can play the generation of the water resources phenomenon that cuts the waste indirectly, cannot initiatively take water saving measures-auto-closed water tap etc.This device comprises more electronic component, thus makes system manufacture, the raising of installation, maintenance expense, and this device self is also waste the one of electric energy in addition.Therefore, impracticable in the real daily life.

Summary of the invention

The object of the invention is to solve not enough problem of the prior art, for user provides a kind of water saving intervening valve of brand-new practicality, is a kind ofly the situation of water can be issued to and automatically cut off water route object water saving fixtures forgetting to turn off the tap.This device use safety, without the need to other form energy such as applying power.It is easy for installation, without the need to changing original water device, only needing device to be series in water supply line, making this device automatic operation after cutting off the water, can reach using water wisely object by hydraulic principle.

Realizing the technological scheme that above-mentioned functions of the present invention adopts is:

This water saving intervening valve is made up of valve body, spool, one-way valve, rubber pipe, tongs, seal ring, spring; Spool, one-way valve, seal ring, spring etc. are all in valve body, and rubber pipe, tongs are connected to valve body outside, and tongs is used for stepping up rubber pipe;

When described device uses, water flows into through water intake, opening tongs makes water freely enter left end valve pocket through rubber pipe, progressively be full of in left end valve pocket process at water, because hydraulic pressure reason spool moves right, water flows out through water outlet, and after this tongs clamps rubber pipe and keeps closed condition, is now normal water supply; During central cut-off water, due to the reduction of hydraulic pressure, spool is moved to the left, one-way valve is started working, part water has been caused to flow out from left end valve pocket through one-way valve, after a period of time, device reaches stress balance, now spool annular boss left side and seal ring closely cooperate, because tongs is in clamped condition always, make left end valve pocket be in sealing state, namely when resuming water supply, the hydraulic pressure of generation can not make spool move to right, thus ensure that water can not flow out from water outlet, and then reach the effect of self-closing cutout; If user needs to use water, tongs of can checking card when resuming water supply, due to hydraulic pressure and the effect of spring, spool can move to right and open water route, and system returns back to just conventional water.

Now each working state is spoken approvingly of as follows in detail:

1, just conventional water

When this device is not connected with water pipe, in valve, device status as shown in Figure 1, and its medi-spring is in compressive state, and spool annular boss left side and seal ring are fitted, after being connected with water pipe by this device, when startup water, in valve, device status is as shown in Figure 2.When water flows into from water intake, open tongs, allow liquid flow freely in left end valve pocket, along with water is progressively full of valve pocket, the hydraulic pressure of generation can promote spool and move right, and spring is compressed further, thus spool annular boss left side is separated with seal ring, liquid can be flowed out through water outlet.And one-way valve two ends hydraulic pressure is equal in spool moving process, but one-way valve due to contained spring effect so be in closed state always.Reach stress balance and static through certain hour back valve core, clamp water check valve when stable water supply and also make its tight state of retaining clip always, liquid is only flowed out from water outlet, as shown in Figure 3.

2, water supply is interrupted

Supplying water, it is instantaneous as Fig. 4 to interrupt, now one-way valve right-hand member starts to enter working state because hydraulic pressure reduces, liquid in left end valve pocket is flowed out through one-way valve, the pressure produced in valve pocket also reduces thereupon, cause spring also to extend simultaneously thereupon, and finally make spool annular boss left side again fit with seal ring, water outlet is sealed.In the process flowed out through one-way valve at water, slowly reach at one-way valve two ends stressed identical time, one-way valve starts to close, and is in clamped condition always thus makes left end valve pocket reach obturation effect because of tongs.Water outlet encapsulation situations is as Fig. 5.

3, resume water supply

When resuming water supply, in valve, device status as shown in Figure 6, because tongs is in clamped condition, liquid cannot flow in left end valve pocket through rubber pipe, and the liquid flowed into through water intake compresses one-way valve right-hand member more, one-way valve is in and more closes state, thus under making left end valve pocket be in better sealed environment.Because left end valve pocket is in good closed state, immutable by ideal-gas equation its volume known, even if hydraulic shock spool during water again, also it cannot be made to move to right, thus ensure that spool annular boss left side is still in the state with seal ring good contact, sealing due to this place makes liquid only can flow to herein, and can not flow out from water outlet, thus reaches the effect of self-closing cutout when resuming water supply.And when resuming water supply, the reason that water can make the rubber pipe on the right side of tongs be full of because of water when water intake flows into expands, and this phenomenon can be used to whether judge water.

4, startup water state again

As Fig. 7 when needing to recover just conventional water, open tongs, after this this valve body working state is identical with 1 step when just commonly using water.Later use is identical with above 4 steps.

Advantage of the present invention and beneficial effect are: 1, with existing water facilities slitless connection, can, with the installation form of common intervening valve, be installed in existing water supply water route easily, without the need to special mounting requirement; When 2, cutting off the water supply, independently can realize water-saving function, close water route; During water supply, do not affect normal use; 3, design ingenious, cost of production, replacing, maintenance expenses are lower, meet ordinary family daily expenditure level.4, the use of hydraulic principle equipment self environmental protection and energy saving that are, use hydraulic pressure during work, without the need to other energy supply equipment.
