Abstract
The utility model relates to a pedal liquid-control flushing valve. Utilizing the theory of hydraulic branch control, the pedal liquid-control flushing valve is composed of a pedal valve (1), a flushing valve (3), a liquor control pressure inlet (7), a liquor control decompression pipe (8) and anti-fouling flush booster (20), wherein, the pedal valve (1) is connected with the flushing valve (3) by the liquor control pressure inlet (7) and liquor control pressure outlet (8). The utility model has the advantages of simple structure and convenient operation, which is a water saving flushing device.
Description
The utility model discloses a kind of novel, be applicable to foot-operated hydraulic control flushing valve public, civilian sanitary fittings.
Existing water flushing device adopts high level cistern or hand push type flushing valve more.High level cistern and hand push type flushing valve all belong to disposable quantitative flushing.Therefore, it can't control water supply volume according to the flushing situation, thereby has caused the waste of water supply volume.Especially in hospital or public place, pull or hand by flushing effort but also inconvenient, unhygienic not only.
The utility model is exactly a kind of foot-operated hydraulic control flushing valve that utilizes hydraulic control that proposes according to the defective that existing flusher exists.
The utility model mainly is made up of foot valve, hydraulic control pressure inlet, hydraulic control relief pipe, flushing valve and antifouling helping towards device.
The utility model is to adopt hydraulic pressure to divide the control principle, utilizes the switching that the pressure promotion of tap water flushing valve valve stamen own comes control valve in the running water pipe.On being put in ground or imbed ground foot valve nobody when jamming on, valve body is in closed condition, valve stamen upper cavity part and lower cavity part in flushing valve this moment are in isopiestic state, simultaneously, because valve stamen upper cavity part has a spring to apply pressure to the valve stamen, make upper cavity part to the gross pressure of valve stamen greater than the pressure of valve stamen lower cavity part tap water to the valve stamen, cause flushing valve to be closed.
When foot valve is stepped on, the valve stamen pressurized in the foot valve and moving down, and make liquid pressure inlet and liquid relief pipe all with atmosphere UNICOM.The upper cavity part pressure decline that link to each other with the liquid pressure inlet this moment, and upper cavity part and spring pressure are lower than lower cavity part pressure.Under pressure differential promoted, the valve stamen was moved to the left, and opening of valves passes through tap water, and through antifouling help towards device with can carry out strong flushing after air mixes.In case pin is removed foot valve, then the valve stamen moves in the spring action down below and resets, and flushing valve upper cavity part pressure is equated with lower cavity part, but owing to the effect of the timing hole of opening on spring and the flushing valve valve stamen, can make the valve time-delay closing.
Fig. 1 is the structural representation of the utility model most preferred embodiment.
As seen from Figure 1, foot valve 1 is coupled together by hydraulic control pressure inlet 7 and hydraulic control relief pipe 8 with flushing valve 3.Wherein, the rubber sealing boot 11 in the foot valve 1 is pressed on by garden type joint ring 10 on the valve shell 17 of foot valve 1, and valve stamen 2 and is followingly supported by the spring 14 that is positioned on the bottom 16 below rubber sealing boot 11.Be provided with O RunddichtringO 13 at valve stamen 2 and 17 of valve shells, and on valve shell 17 and two surfaces that bottom 16 contacts, respectively add pad 15 sealing together.Spring 9 in the flushing valve 3 is supported in 4 of closed valve pocket 6 and U type valve stamens, the garden shape timing hole 23 that U type valve stamen 4 tops have a specific dimensions communicates with lower cavity part 21, and 19 of U type valve stamen 4 and running water pipes accompany sealing mat 12, have hole, a garden in addition in the bottom side of closed valve pocket 6, make upper cavity part 22 increase pipe 7 and communicate that closed valve pocket 6 and running water pipe 19 are by being threaded with the hole that open on valve shell 17 tops of foot valve 1 by hydraulic control.
The course of work of the utility model most preferred embodiment is: when the people tramples rubber sealing boot 11, valve stamen 2 pressurizeds move down, cause hydraulic control pressure inlet 7 to communicate in valve stamen 2 by water swivel 18, make that upper cavity part 22 internal pressures in the flushing valve 3 descend with water in the hydraulic control relief pipe 8.At this moment, upper cavity part 22 is with the pressure of spring 9 with less than the tap water pressure in the lower cavity part 21.Under pressure differential promotes, valve stamen 4 is moved to the left, valve port open make tap water by and through antifouling help towards device 20 with can carry out strong flushing after air mixes, move on valve stamen 2 is understood under spring 14 acts in case pin is removed rubber sealing boot 11 and reset, thereby the upper cavity part 22 of flushing valve 3 is equated with lower cavity part 21 hydraulic pressure, by means of the effect of the timing hole of opening 23 on spring 9 and the valve stamen 4, but valve stamen 4 automatic delay functions.O RunddichtringO 13, O RunddichtringO 5 in installing in addition, sealing mat 12 and sealing mat 15 are the device sealing, water proof is set.
The utility model is simple in structure, and is easy to use, utilizes operated by foot, not only health but also time saving and energy saving; Adopting simultaneously delay-self-closing, water-saving result is significantly improved, is hospital, public affairs Be total to sanitary installation and the comparatively desirable water flushing device of family.
Claims (1)
1, a kind of foot-operated hydraulic control flushing valve.Mainly form, it is characterized in that by foot valve 1, flushing valve 3, hydraulic control pressure inlet 7, hydraulic control relief pipe 8 and antifouling helping towards device 20: foot valve 1 by valve shell 17, garden shape seal joint 10 by sealing mat 15 and valve shell 17 contacted bottoms 16 and by garden shape seal joint 10 be pressed in valve shell 17 upper edges rubber sealing boot 11, forming below the rubber sealing boot 11 and by the valve stamen 2 that is supported in spring 14 supports on the bottom 16, the O RunddichtringO 13 between valve shell 17 and valve stamen 2; Flushing valve 3 has the O RunddichtringO 13 of 6 of the timing hole 23 that communicates with lower cavity part 21 of certain size, spring 9 that be positioned at upper cavity part 22 and that be supported in 4 of closed valve pocket 6 and U type valve stamens, U type valve stamen 4 and closed valve pockets and forms by the closed valve pocket 6 that connects with thread forms and running water pipe 19, U type valve stamen 4, in U type valve stamen 4 top center positions, and 4 of running water pipe 19 and U type valve stamens lean on sealing mat 12 to seal.
