Foot-controlled photoelectric adjustable valve

Abstract

The invention provides a foot-controlled photoelectric adjustable valve which comprises a valve body, a valve element, an electromagnetic controller and a foot-controlled plate. The electromagnetic controller is connected with the valve element and controls the valve body to be opened and closed. The foot-controlled plate is placed on the ground. The vertical face of the foot-controlled plate is provided with two or more photoelectric switches for horizontal irradiation. The photoelectric switches are connected with the electromagnetic controller through circuits. The electromagnetic controller is adjustable. The foot-controlled photoelectric adjustable valve can be opened when the foot of a user is placed at the approximate position of the photoelectric switches on the foot-controlled plate; different signals are emitted through the multiple photoelectric switches, and the water yield is controlled by the electromagnetic controller.

Description

technical field [0001] The invention relates to the technical field of valve equipment, in particular to a foot-controlled photoelectric adjustable valve. [0002] Background technique [0003] The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. According to the shape of the spool in the valve, it can be divided into ball valve, butterfly valve, cone valve and so on. There are also various ways to start the valve. Generally speaking, it can be divided into two types: manual and automatic. Among them, the photoelectric start method is a common way for people to start. For example, in public places, the photoelectric switch is often placed under the valve. When people's hands are close to the switch, the valve will automatically discharge water, and once people's hands leave the photoelectric range, the valve...

AI Technical Summary

Problems solved by technology

But when people use such valves to wash their hands or wash other items, their hands will shake up and down. When shaking, the hands may be far away from the photoelectric part, causing the solenoid valve to be closed, which will cause inconvenience to people when washing their hands or other things.

Moreover, the photoelectric solenoid valves commonly used in public places are quantitative valves, that is, once the valve is opened, the flow rate is fixed, but people need different flow rates when washing hands or other different things. There will be a certain amount of waste, as well as some inconvenience during cleaning
