Abstract

The utility model relates to a pedal water valve, comprising a valve body, a valve plug, a reset spring, and a lever mechanism. The utility model is characterized in that the valve plug is provided with a push rod which is sheathed with the reset spring. The water valve is opened and closed by that the lever mechanism is treaded to drive the valve plug to move, and a water inlet and a water outlet are communicated, the reset of the valve plug can be realized by the reset spring, and the channel of the water inlet and the water outlet is cut off. The utility model has the advantages of sanitation, convenience, and water saving. The utility model is especially suitable for public places and hospitals.

Description

Pedal water-valve

The utility model relates to a kind of pedal water valve, comprises valve body, valve plug, Returnning spring and leverage.

At present, known water valve, the unlatching of implementing water valve is that armrest is screwed its handle, valve plug moves up and down the opening and closing of finishing water valve with the rotation of the screw rod on the handle.It is longer that this screw-on water valve exists the open and close time, cause the waste of water, especially in public places, as places such as hospital, lavatories, various infectiousness patient's water contacting valves screw handle, easily catch virus, bacterium, the use phychology that often causes the user only to open to be not related to, cause the waste of artificial water, use not only inconvenience but also unhygienic simultaneously.

The purpose of this utility model is the deficiency at above-mentioned screw-on water valve, design a kind of pedal water valve, this water valve comprises valve body, valve plug, Returnning spring, leverage, foot treadle, and the moving foot treadle that tramps with one's feet comes the opening and closing water valve, not only convenient and healthy, but also using water wisely.

The purpose of this utility model is to realize like this, this water valve comprises that valve body, valve plug, Returnning spring, leverage, foot treadle valve plug and valve cavity are slidingly matched, water intake, the water outlet of valve plug and valve body are sealed and matched, the valve plug upper end is provided with and is installed with Returnning spring on push rod, the push rod, Returnning spring one end contacts with valve plug, the other end contacts with cover plate on the valve body, push rod passes the valve upper cover plate, and the tension arm of leverage connects with push rod, and the pressure arm of leverage connects with foot treadle.

Its valve plug also can be provided with the water port, and implement with the scheme that water intake and water outlet communicate the water port.

Further describe the utility model below by accompanying drawing

Fig. 1 is the utility model enforcement structural representation just

Fig. 2 is another embodiment's of the utility model a structural representation

Fig. 1. among Fig. 2,1 valve body, 2 valve plugs, 3 Returnning springs, 4 leverages, 5 push rods, 6 cover plates, 7 water intakes, 8 tension arms, 9 pressure arms, 10 foot treadles, 11 water outlets.

Among Fig. 2,12 water ports

Fig. 1. among Fig. 2, when the need water, pin steps down on the foot treadle (10), under leverage 4 effects, tension arm (8), pressure arm (9) moves down, the push rod that connects with tension arm (5) is under the pulling of tension arm (8), valve plug (2) is along with push rod (5) moves toward valve cavity, intake tunnel and exhalant canal are open-minded gradually, and water flows out from water outlet (11), among Fig. 2 along with valve plug (2) up moves, when the water port in the valve plug (12) and water intake (7) and water outlet (11) when communicating gradually, water flows out from water outlet (11).

As user not during water, pin unclamps foot treadle under the effect of Returnning spring (3), and valve plug resets rapidly, finishes the action of closing water automatically.

The utility model embodiment makes valve body, the used material of valve plug can adopt cast iron, plastics, copper.

The utility model is owing to adopt opening and closing foot-operated and leverage and back-moving spring enforcement water valve, and therefore, this water valve has health easy to use, the advantages such as water saving.
