Abstract

The invention discloses a controllable pedal water supply valve, and relates to a water flow control valve. The controllable pedal water supply valve comprises a water valve pedal of a water discharging device, a valve core and a valve body, and is characterized by further comprising a reset pedal of a water stop device, a sleeve frame, a rotary shaft, a locating rod, a fixing frame and a tensionspring. The controllable pedal water supply valve has the benefits as follows: the water demand quantity is large; when a water tap cannot be turned on by a hand, the pedal water supply valve is usedand the water valve pedal does not need to be stepped for long time; and the water tap can be turned on and off to discharge water and stop water by stepping on the water valve pedal twice, so that the water flow can be easily controlled. Therefore, the controllable pedal water supply valve can be largely applied to hospitals, factories and daily life.

Description

A kind of controlled pedal water feeding valve

Affiliated technical field:

This product technology relates to a kind of Water flow control valve.

Background technique:

Prior art: pedal water feeding valve: comprise that water valve is stepped on, Returnning spring, valve body, valve body is provided with water intake, water outlet, and its shortcoming is: when water amount was large, foot valve will stepped on always, could keep tap water outlet, just need to ride pedal when such as needs the pond being piled and to unclamp.

Summary of the invention

The technology of the present invention is mainly dealt with problems: at foot valve a lever positioning device is installed, is made foot-operated position be divided into water outlet device and water closing device, make the water flow of foot valve controlled.

Technological scheme of the present invention is: controlled pedal water feeding valve, the water valve that comprises water outlet device is stepped on, spool, valve body, it is characterized in that: comprise that also resetting of water closing device step on, stock, rotating shaft, positioning rod, fixing frame, extension spring, the foot-operated end of stepping at water valve installs one additional near fulcrum running shaft place and resets and step on, specifically at the fulcrum running shaft stock is installed, stock can rotate around the fulcrum running shaft, the stock the other end arranges a framework, the top of framework has a rotating shaft to cross, the top of stepping on that resets is installed in the rotating shaft, the protruding framework of rotating shaft axle, positioning rod one end is installed in the protruding end of rotating shaft, resetting to step on through rotating shaft is connected with positioning rod, and the positioning rod that rotarily drives of rotating shaft rotates around the shaft; The framework bottom be equipped with a bolt with water valve step on cover with its in, the frame end of stock also moves down around the pivot point rotation when pressing when water valve depresses; The back of valve body is equipped with a fixing frame, fixing frame be provided with a fixed body, fixed body has positioning step, the fixed body bottom is linked to each other with the positioning rod middle part by extension spring, the upper end of positioning rod contacts with the top of fixed body, and valve body is to be installed on the use equipment by fixing frame.

Work as water valve during use and depress pressure, water valve is stepped on the other end valve body inner spool is backed down the tap water flows valve body on the one hand, the frame end that another side drives stock presses down, the positioning rod that links to each other with framework moves down, make its upper end under the extension spring effect, snap in the positioning step of fixing frame, valve body can not recover closed condition when decontroling pin, and water supply valve stays open state like this; When water flow reaches when needing the water yield, step on as long as stepping on resets, reset to step on and drive the rotating shaft rotation, rotating shaft drives again the positioning rod rotation, make the upper end of positioning rod jump out the positioning step of fixed body, at this moment unclamping resets steps on, and water valve is stepped under the effect of valve body inner spring and rotated around the pivot point axle, recover to close water state, close current.

Beneficial effect of the present invention is that water demand is large, in the situation about can not turn on the tap with hand, use the pedal water feeding valve stepping on for a long time water valve and step on, can enough one open-one close secondary pin step on to control water outlet and the Guan Shui of tap, can easily control water flow, alleviate staff's workload.

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

Description of drawings:

Fig. 1 plan view of the present invention

Fig. 2 side view of the present invention

Fig. 3 plan view of the present invention

Among the figure: water intake 1, water outlet 2, fixing frame 3, positioning step 4, positioning rod 5, rotating shaft 6, reset step on 7, water valve steps on 8, bolt 9, framework 10, rotating shaft cap 11, fulcrum running shaft 12, stock 13, valve body 14, fixing frame fixing bolt 15, fixed body 16, spool 17, extension spring 18.

Embodiment:

Diagram: controlled pedal water feeding valve, comprise that water valve steps on 8, spool 17, valve body 14, it is characterized in that: also including resets steps on 7, stock 13, rotating shaft 6, positioning rod 5, fixing frame 3, extension spring 18, stock 13 1 ends are installed on the fulcrum running shaft 12, stock 13 can rotate 12 around fulcrum and rotate, and stock 13 the other ends arrange a framework 10; Framework 10 is welded by two steel discs are parallel, and a rotating shaft 6 is equipped with on two steel disc tops, and the bottom has bolt 9 to connect; Reset and step on 7 top and be installed in the rotating shaft 6, rotating shaft 6 protruding frameworks 10, the lower end of positioning rod 5 is installed in rotating shaft 6 overhanging ends; The positioning rod 5 that rotarily drives of rotating shaft 6 rotates around the shaft; Water valve is stepped on 8 and is sandwiched on the framework 10 between the bolt 9 and rotating shaft 6, steps on 8 when pressing down when water valve, and water valve is stepped on 8 and pressed down framework bolt 9, and framework 10 connected set framves 13 also are rotated down around fulcrum running shaft 12; The back of valve body is fixed with a fixing frame 3, fixing frame 3 be provided with a fixed body 16, fixed body 16 has positioning step 4, fixed body 16 bottoms are linked to each other with positioning rod 5 by extension spring 18, the upper end of positioning rod 5 contacts with the top of fixed body 16.

Described framework 10 also can be to be bent into U-shaped by a steel disc, and rotating shaft 6 is installed in U-shaped top, can save bolt 9 like this.

Described fixing frame 3 can be a part of using the pedal water feeding valve device, and the installation that forms a complete production network of fixed body 16 and valve.
