Description

Autocontrol valve

The present invention relates to a kind of automatic close-type valve, the particularly autocontrol valve that when continuous flow reaches some, just can close automatically.

Water is lifespring, the whole world is being faced with the threat of water resources wretched insufficiency, but we have really often seen many units, the water tap in public place particularly, owing to forget and close or be not closed completely, even secondary pollution is reluctant to close when being afraid of to close, and causes running water, the phenomenon of a large amount of waste water resources.In the family, forget when also the someone gos out often and close water tap or pipe fitting damages suddenly, metal run out in a large number and cause, have in addition cause floods to flood oneself and the article and the finishing of resident family downstairs, bring unnecessary loss and trouble to people's life.Although existing now part induction type etc. is closed water tap automatically and appeared on the market, because kind is single, price is higher, and water saving but takes reason such as electricity can not form large-scale production, is difficult to satisfy the demand of various models, all kinds of purposes and domestic consumer.

The purpose of this invention is to provide and a kind ofly can control the universal autocontrol valve of a plurality of all kinds of water appliances, pipe fitting and automatic close-type water tap independently simultaneously.It can be closed when continuous flow reaches the quantity of design automatically, can effectively avoid waste and causes disaster.

The object of the present invention is achieved like this: along the Way in of valve body, valve is packed in the valve base in the valve pocket, make the tooth engagement of tooth on the valve guide rod and reduction gearbox output shaft, this output shaft meshes indirectly by speed reducer speed reducer and driving shaft, and the impeller in the valve pocket is fixed on this driving shaft.

When the water impact impeller makes the impeller rotation, impeller drives the driving shaft rotation, the high speed rotating of driving shaft drives driven axle and slowly rotates after speed reducer slows down, the tooth of the tooth pulling valve guide rod on the driven axle, valve is slowly moved to valve base, and valve just thoroughly seals valve base when reaching design discharge.

Because what this control valve adopted is the assistance type mechanical structure of taking advantage of a situation, so technology is simple, economy and durability, independence is good, is not subjected to environmental constraint, is difficult for breaking down, not water clock.Use running water wasting phenomena that the present invention can thoroughly stop tap water and because of race emit water cause water logging oneself and downstairs the floods of resident family's article and finishing take place.This valve is widely used, install simple, can be vertically, level arbitrarily uses, except tap water, also can be applicable in the facility of other various liquid, gas.

The present invention is further described below in conjunction with drawings and Examples.

Among the figure: 1, valve body 2, equalizing orifice 3, valve 4, return spring 5, discharge orifice 6, valve base 7, impeller 8, equilibrium valve 9, gear box cover 10, output shaft 11, speed reducer 12, driving shaft 13, Luo Ding 14, Way in 15, valve guide rod 16, control knob

Embodiment 1

As shown in Figure 1, return spring (4) is contained on the valve guide rod (15), then valve (3) in the Way in (14) of valve body (1) is packed valve base (6) into, make the tooth engagement of tooth on the valve guide rod (15) and output shaft (10).This shaft (10) is indirect and driving shaft (12) engagement by the speed reducer in the speed reducer (11), and the impeller (7) in the valve pocket is fixed on this driving shaft (12); In addition in the speed reducer (11) of sealing, there are two equalizing orifices (2) to communicate with the valve pocket of both sides, valve base (6) front and back respectively, wherein with that equalizing orifice that the inlet side valve pocket communicates on, an equilibrium valve (8) is installed, under the effect of spring, sealing this equalizing orifice usually.For the encapsulation that guarantees speed reducer (11) and easy to process, utilize 6 Luo Ding (13) that gear box cover (9) is fixed on the valve body (1).

When water by inlet when outlet is flowed, impeller (7) is subjected to momentum effect to begin rotation, driving shaft (12) is rotation synchronously also, and the speed reducer drive output shaft (10) that passes through in the speed reducer (11) slowly rotates, output shaft (10) by the tooth of the pulling valve guide rod of the tooth on the axle (15), makes valve (3) close to valve base (6) gradually again.If at this time close water appliance, stop water, impeller (7) just stops operating, return spring (4) will push back the origin-location to valve, simultaneously, output shaft (10), driving shaft (12) and impeller (7) also can be promoted by the tooth of valve guide rod, go back to original state.Under normal circumstances, this valve comes to this and works repeatedly.But close or reason such as damage owing to forgetting, the water that does not stop makes impeller not stop rotation, and when last continuous flow had reached design quantity, valve (3) will thoroughly close valve base (6), and current are stopped.At this moment, the valve both sides have produced pressure difference, and the pressure of inlet side equals the hydraulic pressure in the water pipe, and the pressure that exports a side is zero.Because the elastic force of return spring (4) so can't separate valve (3) and valve base (6), can only remain closed condition less than pressure difference.Function that this valve can close when continuous flow reaches some automatically that Here it is.Resume water supply if desired, as long as the closeall water switch of using of elder generation, press the control knob (16) of equilibrium valve (8) then, make the water of inlet side enter outlet one side by two equalizing orifices (2), when the pressure of valve (3) both sides equates, return spring will be opened valve and back into the position automatically, recovers normal water supply.

General family is as long as be contained in 50 liters control valve near oneself water meter, just can neither influence normal water, can guarantee again that whole family's whichever water tap, valve are forgotten closes or damages suddenly, run emit 50 premium on currency after this valve all can close automatically, just can not cause floods.Because of the continuous water consumption of the maximum of family is no more than 40 liters, generally do not reach automatically and close, if in case continuous water consumption reaches 50 liters, control valve is closed automatically, also very simple, as long as water appliance is closed, then, press lower-pilot valve (16) about one minute, just can recover normal use.

Embodiment 2

This is an automatic close-type water tap that utilizes the present invention to design.As shown in Figure 5, in the valve base (6) of valve (3) in Way in (14) is put into valve body (1), make the tooth engagement of the tooth and the output shaft (10) of valve guide rod (15), output shaft (10) is by speed reducer (11) and driving shaft (12) engagement indirectly, and the impeller (7) in the valve pocket is fixed on this driving shaft (12); Control knob (16) is equipped with above by stretching out in the gear box cover (9) in the upper end of output shaft (10) in addition; Valve (3) is installed a return spring (4) to the tight performance of valve base (6) sealing at the top of valve (3) when guaranteeing that hydraulic pressure is low, is installed in the valve pocket by jump ring (7).

This automatic close-type water tap is the same with ordinary faucet, arbitrarily switch water and close water.But after the tap of fetching boiling water, need keep opening state, otherwise as long as hand leaves, control knob (16) will be under the effect of impeller (7), to back rotation with hand.After the water consumption that uses up setting (1 liter or 2 liters), just close automatically.Can thoroughly solve the waste problem of running water like this.This water tap is applicable to various places uses, the particularly washbasin of catering trade and all kinds of toilets washbasin.Use this self-closing water tap, not only saved but also health, no longer cause secondary pollution because of closing water.
