Abstract

The utility model relates to a quick opening and closing water-saving water tap, which is composed of a handle, a piston, a valve cover, a pressure plate, a rubber diaphragm and a valve body. The water tap is characterized in that the water separation rubber diaphragm which can upwards move flow water pressure is arranged in the valve cavity which is composed of the valve cover and the valve body, the upper part of the rubber diaphragm is fixedly connected with a convex pressure plate, the piston which is on the pressure plate can freely move from top to bottom, the upper part of the pressure plate is connected with a valve cover which is contacted with the handle, an adjusting pad is arranged between the pressure plate and the piston for adjusting the gap between the pressure plate and the piston. The water tap has simple structure, quick water cutting and convenient maintenance and can effectively prevent leakage, and the cost is almost the cost of a traditional water tap.

Description

The snap switch water conserving tap

The utility model relates to a kind of snap switch water conserving tap, belongs to industry and civilian industry small-bore pipeline terminal control piece.

Traditional water tap, water nozzle are to realize switch by following structure: the turn handle, and the band valve rod moves up and down along screw thread, and spool is moved upward along the valve rod center under hydraulic action, realizes opening state; Otherwise spool is under the valve rod effect, and external force surpasses hydraulic pressure, and spool moves downward, and realizes closed condition.Its feature is: opening and closing are not to realize moment, easily cause liquid medium to run off; Sealing surface is wearing and tearing and scratch easily, causes to be not closed completely, and has both influenced working life, also forms water clock; The valve rod place need be provided with filler device specially, requires often to add filler, both makes troubles to use, increases workload, also easily causes pipe liquid to run off or environmental pollution.In the last few years,, some had occurred and had the water tap of opening function soon, but adopted tap structure or ball-valve structure as many in order to overcome the defective of above-mentioned traditional water tap.Easily do not leak but overcome the valve rod place yet, can not carry particle or easily separate out the defective of crystal; And having the price height that brings owing to the accuracy of manufacturing height, working life, length was repaired difficult new weakness.

The purpose of the present utility model: be to provide a kind of snap switch water conserving tap, wish its have simple in structure, switch is convenient, do not have to leak, the advantage of easy to maintenance, low cost.

This snap switch water conserving tap is made up of handle (2), piston (3), valve gap (4), pressing plate (6), elastomer diaphragm (7), valve body (8).It is characterized in that described valve body (8) and valve gap pass through scyewed joint, described elastomer diaphragm (7) be folded in both connecting parts and sit place two-way valve body (8) cut the water place, pressing plate (6) closely bonds with elastomer diaphragm (7), piston (3) bottom is fixed on the pressing plate boss, the cavity of valve gap (4) is stretched on its top, and with valve gap (4) on handle (2) butt; Described handle (2) is connected with valve gap (4) by pin (1); Described spacer (5) then is located on the boss of pressing plate (6) and piston (3) connecting part.

Snap switch water conserving tap according to the technique scheme design has not only changed the leakage slow in one's movements, easy of traditional water tap, has caused the big defective of water waste; And remedied required precision height such as ball valve, plunger valve, cost height, repaired difficult defective.The price of product is very nearly the same with the tradition tap simultaneously, is the products that save energy and resources that a kind of utmost point has promotional value.

Accompanying drawing 1～3 has provided structural representation of the present utility model.Three kinds of model structure unanimities shown in the figure only are slightly to change in the handle moulding.

Below in conjunction with accompanying drawing, further describe the utility model, and provide embodiment.

In actual use, utilize the mechanism of lever and cam, when we upwards mentioned handle (2), handle was done circular motion on pin ruthenium (1) fulcrum, piston (3) forms the gap with handle (2) head, because the jacking effect of hydraulic pressure, elastomer diaphragm (7) are by jack-up, piston and then rises, when the referred highest order of handle (2), to the extreme higher position, this moment, opened, and is in the flow maximum rating by water tap by the top of the pressing plate (6) on the elastomer diaphragm (7) for piston (3); Otherwise when handle (2) when being pressed, piston (3) will be depressed by the protrusion position of handle (2), and elastomer diaphragm (7) also correspondingly is pressed downward with pressing plate (6), until with complete combination of valve body (8) sealing surface, this moment, tap was in closed condition.In the technical program, handle (2) moves the dead point up and down and is made progress to peak and the control of valve gap (4) table top by piston (3) respectively.The real crack of piston (4) lower end spacer quantity and controllable thickness system tap closed position, promptly after tap uses a period of time, elastomer diaphragm (7) produces plastic deformation, can be by increasing the working life that spacer quantity and thickness are controlled the flow of tap and prolonged tap.In addition, this technological scheme belongs to does not have the wearing and tearing valve body structure.Therefore switch is snap action basically in addition, and the opening and closing time has only 1/3 of traditional common water nozzle, can remedy the defective of tradition tap preferably, and it is simple in structure, and cost is low, easy to maintenance, is a kind of not only practical but also energy-conservation novel valve.

Claims

1, a kind of snap switch water conserving tap is made up of handle (2), piston (3), valve gap (4), pressing plate (6), elastomer diaphragm (7), valve body (8), it is characterized in that described valve body (8) and valve gap (4) pass through scyewed joint; Described elastomer diaphragm (7) is folded in both connecting parts, and sit place two-way valve body (8) cut the water place; Described pressing plate (6) and elastomer diaphragm (7) closely bond, and piston (3) bottom is fixed on the boss of pressing plate, and the cavity of valve gap (4) is stretched on its top, and with valve gap (4) on handle (2) butt; Described handle (2) is connected with valve gap by pin (1); Described spacer (5) then is located on the boss of pressing plate (6) and piston (3) connecting part.
