Foot pedal control-type valve

Abstract

The invention discloses a foot pedal control-type valve which comprises a valve seat; the two ends of the valve seat are respectively provided with an inlet and an outlet; the cavity of the valve seat is provided with a valve hole which is communicated with the inlet; a movable cover is arranged above the valve seat; a movable rod which can move up and down along the cavity thereof is installed in the movable cover; the upper part of the movable rod is connected with a steel wire which passes through the movable cover towards the outside; the terminal of the steel wire is connected with a foot pedal switch which controls the stretch of the steel wire; a spring is connected between the movable rod and the movable cover; a cylinder cover which separates the cavity from the inner cavity of the valve seat is arranged below the cavity; the movable rod passes through the cylinder cover and is provided with a sealing rubber film which corresponds to the valve hole at the lower end of the movable rod; the foot pedal control-type valve can control the up and down movement of the movable rod by the foot pedal and further operates the opening and closing of the sealing rubber film; when the valve is needed to be opened, foot can be used for pressing the foot pedal; pollution to the hand is not caused; and the demands of people in the aspects of health and resource conservation can be met.

Description

technical field [0001] The invention relates to a valve, in particular to a foot-operated valve. Background technique [0002] Most of the valves currently in use are manual valves, such as tap water valves, toilet flush valves, shower water valves, etc., which must be operated by hand, which is unhygienic and easy to cause cross-infection, especially in public places. In order to keep the washed hands from being polluted, some people do not turn off the water valve after use, resulting in a waste of water resources. The disadvantages of manual valves are becoming less and less suitable for people's needs for sanitation and resource conservation, especially in the case of more and more epidemics, the sanitation and waste problems caused by the use of such manual valves in public places more prominent. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a foot-operated valve, which can meet people's demands on sanit...
