Abstract
The utility model discloses a pedal self-closing water-saving valve which is composed of a pedal, a sliding rod, a valve body, a spring, etc. The on-off of the water valve is controlled by the weight of an operator. The pedal is stepped, the sliding rod is pressed, a conical body on the sliding rod and the conical bore of the valve body are disengaged, and a water inlet and a water outlet are connected as a path for completing opening operation; the pedal is released when the operator leaves, the sliding rod is lifted under the action of spring force, the conical body on the sliding rod and the conical bore of the valve body are jointed, and the water inlet and the water outlet are disconnected for completing closing operation. The utility model which has the advantages of simple structure and convenient operation and has the multiple functions of flushing, showering, washing, etc. is suitable for a room, a bathroom, a toilet, etc.
Description
The utility model relates to a kind of foot-operated auto cut-off water saving valve.
Existing water valve mostly adopts the rotating switch of staight shank, and this valve has 2 deficiencys: the one, need to finish switch motion with hand, and be not related to as only opening, then the water waste is serious; The 2nd, valve core is feed screw nut's form, and thread surface is worn and torn easily, causes leaking.In addition, also have a kind of controlled self-closing flushing valve, need to press the button the ability boiling water with hand, can only do flushing usefulness, function ratio is more single.
The purpose of this utility model be to provide a kind of can be by the energy saving device of user self body weight control switch, be applicable to the multiple use such as flushing, shower, washing of occasions such as house, bathroom, toilet.
The utility model is achieved in that has two or three at conplane entery and delivery port in valve body, with entery and delivery port plane of living in intersect vertically have on the direction small end up, big end conical bore down, the conical slide bar of one bottom band is housed in it, be connected with a pedal on the slide bar, it is boiling water that the people sets foot on, the people leaves promptly closes water, reaches the purpose of water saving.
Be further described below in conjunction with the main structure and the working principle of accompanying drawing model utility.
Fig. 1 is foot-operated auto cut-off water saving valve's a plan view.
With reference to Fig. 1: on the valve body 6 of interior band conical bore, the conical slide bar 7 of one bottom band is housed, there are an entery and delivery port that is communicated with and conical bore to intersect in the middle of the valve body 6, the cone of slide bar 7 is drilled with two apertures that communicate at sidepiece and bottom respectively, aims at water intake all the time for making side opening, has a vertical slot on slide bar 7 tops, aperture is in same plane on this vertical slot direction and the conical surface, groove is embedded with a location screw 5, the circumferential location of realizing slide bar 7, and seal ring 4 seals.Pedal 1 adopts threaded joint with slide bar 7 tops, between pedal 1 and valve body 6 tops spring 2 is arranged, turn pedal 1 can regulate slide bar 7 press down stroke, promptly adjust water yield size.
When pin pushes down on the pedal 1 the time, people's body weight is depressed slide bar 7, and the cone of slide bar 7 bottoms and the conical bore of valve body 6 are thrown off, and entery and delivery port is linked to be a passage, finishes the boiling water action.
When pin unclamped pedal 1, weight disappeared, and the cone on the slide bar 7 is lifted on automatic under the effect of spring 2, fitted with the conical bore on the valve body 6, disconnected entery and delivery port, finished the pass hydrodynamic(al) and did.At this moment, press water continues to enter the awl end by the aperture on the conical surface and keeps a thrust that makes progress, and guarantees that water shutoff is reliable, because of there is water at the awl end, can slowly descend when pedal 1 is stepped on once more, and water-outlet quantity is ascending.
In addition, valve body 6 bottoms have a base plate 10 to be connected with valve body 6 with Sealing 9 by bolt 8, and the sealing on slide bar 7 tops is finished by two O RunddichtringOs 3.
Claims (4)
1, a kind of foot-operated auto cut-off water saving valve, form by pedal, slide bar, valve body, spring etc., it is characterized in that: a conical bore is arranged in the valve body 6, water intake and water outlet are arranged on the plane that intersects vertically with it, slide bar 7 tops have screw thread to be connected with pedal 1, and slide bar 7 bottoms are that the upper end is little, the cone that the lower end is big, tapering and valve body 6 taper holes have spring 2 together between pedal 1 and valve body 6 tops.
2, foot-operated auto cut-off water saving valve according to claim 1 is characterized in that: be drilled with an aperture on the conical surface of slide bar 7 cones and communicate with the awl end.
3, according to claim 1,2 described foot-operated auto cut-off water saving valves is characterized in that: have a vertical slot on the cylindrical body on slide bar 7 tops, the aperture on this vertical slot and the lower cone face is in same plane.
4, foot-operated auto cut-off water saving valve according to claim 1 is characterized in that: valve body 6 can be made two logical and two kinds of patterns of threeway.
