Water purifier solenoid valve

The water purifier solenoid valve is a device that uses the electromagnetic principle to control the switch of fluid (mainly water). It is mainly composed of electromagnet, valve body and valve core. The movement of the valve core is controlled by the attraction and release of the electromagnet, thereby realizing the opening and closing of the water flow.

Product Description

The working principle of the water purifier solenoid valve is based on the principle of electromagnetic induction. When the electromagnet is acted upon by electric current, it will generate magnetic force, which will push the valve core to move, thereby changing the channel state of the valve body and achieving control of the water flow. Specifically, when the electromagnet is energized, the magnetic force attracts the valve core to move, causing the valve body channel to open and allowing water to flow through; when the electromagnet is de-energized, the magnetic force disappears, the valve core is reset under the action of the spring, the valve body channel is closed, and the water flow is cut off.

Inlet valve: installed at the water inlet of the water purifier, the purpose is to control the opening and closing of the water circuit of the water purifier, power on and off.
Wastewater valve: installed at the wastewater of the water purifier, the purpose is to control the wastewater flow of the water purifier, the wastewater valve is normally open
High-pressure switch: installed on the water circuit between the RO membrane pure water port and the pressure barrel, the function is to control the opening and closing of the circuit of the water purifier
Low-pressure switch: installed on the water circuit between the water inlet and the filter element, the function is to prevent the water pump from working without water and damaging the water pump
18-second solenoid valve: installed on the wastewater port of the RO membrane, the purpose is to adjust the wastewater discharge ratio; control the backwash function
