Description

A kind of time-delay flushing valve
Technical field
The present invention relates to a kind of flushing valve, be meant a kind of time-delay flushing valve especially.
Background technique
Now, the time-delay flushing valve is used for public places such as public lavatory, station, hotel in a large number, its using water wisely effectively on the one hand, on the other hand, because it can be closed within a certain period of time automatically, the user need not to touch tap with hand again after cleaning is finished, and operation is very easy.Disclose a kind of time-delay valve among the CN2733129Y, it comprise bring into, the valve body of water outlet, the time-delay chamber that the dividing plate and the control discharge time of water-in and water-out are at interval arranged in the valve body, the centre of dividing plate offers through hole, in the time-delay chamber, buoyancy aid is installed by through hole, the top of buoyancy aid is equipped with spool, on the madial wall in described time-delay chamber, have gutter with the cooperation place of buoyancy aid.Yet, in existing above-mentioned time-delay valve, the delay performance of time-delay valve (mainly the aperture by gutter determines) has been finished setting when dispatching from the factory, and can't be regulated according to actual use condition, therefore, when same time-delay valve is used for the depotition cock of different water supply pressures, different water supply water temperatures, can cause delay time difference (generally in 3~15 seconds, floating), at this moment, if delay time is longer, then can not reach the requirement of water saving, and if delay time is shorter, then the user need press button once more and could satisfy water yield requirement, uses inconvenience.
Summary of the invention
The invention provides a kind of time-delay flushing valve, to solve the above-mentioned problems in the prior art.The present invention is by tightening and unscrewing gland, make the priming hole that is fastened on the elasticity diversion cover between gland and the adjustable lever the aperture or become big or diminish, and then make that the delay time of time-delay flushing valve also can be adjusted according to actual use condition.
Technological scheme of the present invention is as follows:
A kind of time-delay flushing valve, the valve body that comprises a upward opening, it has water intake and water outlet, it is characterized in that: be mounted slidably a rigidity adjustable lever in the described valve body, one perforate that is communicated with described valve inleting water mouth is set on this rigidity adjustable lever, on this perforate sheathed one in order to valve body in the seal ring that is tightly connected of the limited part that forms, and under this perforate sheathed one in order to the make progress v-ring of unidirectional outflow of controlled water flow, described valve body water outlet is set on the described limited part, and this V-shaped seal ring then is separated into down valve inner cavity volume and last cavity volume; Extend downward the bottom of this rigidity adjustable lever after the described perforate bending, one round platform portion is formed at the bottom of this perforate, the one elasticity diversion cover that has a priming hole is set in it, this elasticity diversion cover is provided with the round platform portion that described perforate round platform portion uses that is matched with, the rigid gland of establishing a hollow is supported in the below of this elasticity diversion cover, and this gland is connected with the inner thread of described perforate; Be provided with Returnning spring between the inner bottom surface of the lower end of this rigidity adjustable lever and this time cavity volume, its top then fixedly connected stretches out in the pushbutton unit of valve body openings.
During use, downward pressing button, the rigidity adjustable lever moves down, seal ring leaves limited part, and current flow into the back from the valve inleting water mouth and directly flow out the valve body water outlet, at this moment, under the effect of hydraulic pressure, the rigidity adjustable lever whenever moves downward a segment distance, needs will descend the water of respective volume in the cavity volume to arrange upwards cavity volume along the V-shaped seal ring periphery, and Returnning spring is compressed; Release button, the rigidity adjustable lever moves upward under the effect of Returnning spring, but because the effect of hydraulic pressure, the rigidity adjustable lever segment distance that whenever moves upward, the water that need replenish respective volume via the downward cavity volume of priming hole of elasticity diversion cover could continue to move upward, and at this moment, priming hole is big more, the speed that imports current is fast more, rigidity adjustable lever upward speed is fast more, and delay time is short more, otherwise, if priming hole is more little, the speed that then imports current is slow more, and rigidity adjustable lever upward speed is slow more, and delay time is long more, when seal ring moved upward to the limited part position heavily again, flushing valve stopped water outlet.
Among the present invention, by tightening or unscrewing rigid gland, make the priming hole that is fastened on the elasticity diversion cover between gland and the adjustable lever the aperture or become big or diminish, and then make that the delay time of time-delay flushing valve also can be adjusted according to actual use condition.
In the embodiment who recommends, also comprise an anti-blocked shot, an end of this anti-blocked shot stretches in the described priming hole, and with the inwall of a priming hole gap at interval, the other end then is fixed on down the cavity volume inwall or down in the cavity volume on the Returnning spring of setting.
In the embodiment who recommends, described priming hole is circular port, square opening, tri-angle-holed, regular polygon hole, waist shaped hole, Hua Xingkong, slotted eye or strip hole etc.
In the embodiment who recommends, the top of this rigidity adjustable lever socket slidably one is in order to push the connecting rod that it moves downward, be slidably disposed in the connecting sleeve behind this connecting rod separation seal circle, this connecting sleeve fixed cover is located at the top of valve body, roof anchorage one button of this connecting rod, folder is established a Returnning spring between this button and this connecting sleeve, and said structure has constituted described pushbutton unit.Like this, after release button, button can be under action of reset spring return at first, and can remove of the influence of this Returnning spring to the delay time of flushing valve.
In the embodiment who recommends, described valve body comprises that a water inlet body and that is provided with water intake is provided with the water-outlet body of water outlet, and this water inlet body is fixedlyed connected with this water-outlet body separation seal circle.The present invention is divided into into water body, water-outlet body two-part with valve body, and valve inleting water mouth and valve body water outlet are separately positioned on on the water body and water-outlet body, can be convenient to finish the installation of time-delay flushing valve.
In the embodiment who recommends, described elasticity diversion cover is working of plastics or rubber parts.
Relate among the present invention " on ", the D score direction of placing when normally using with the time-delay flushing valve is as the criterion, and is the below with water inlet body present position promptly, water-outlet body and button present position are the top.
By the above-mentioned description of this invention as can be known, compare with prior art, the present invention has following characteristics:
1) the present invention is by tightening and unscrewing gland, make the priming hole that is fastened on the elasticity diversion cover between gland and the adjustable lever the aperture or become big or diminish, and then make that the delay time of time-delay flushing valve also can be adjusted according to actual use condition;
2) the rigidity adjustable lever and the connecting rod that are slidingly connected by setting of the present invention, thus of the influence of push-button reset spring can be eliminated to the flushing valve delay time;
3) the present invention is divided into into water body, water-outlet body two-part with valve body, and valve inleting water mouth and valve body water outlet are separately positioned on on the water body and water-outlet body, can be convenient to finish the installation of time-delay flushing valve.
