  • How w does the electric valve on the water dispenser work?

Water machine solenoid valve is a special tool for water machine, we understand the principle of water machine solenoid valve.It has applicability, reliability, safety, economy and other characteristics, and its internal structure is more complex, and the working principle and classification characteristics as a water fountain solenoid valve a very important knowledge, it is worth us to understand.

Solenoid valve has closed cavity, open a hole in different position, each hole to connect different tubing, cavity piston is among, both sides are two electromagnets, which face the magnet coil electricity body which side will be attracted to, through to control the movement of the valve to open or close the different discharge of oil hole, and the oil hole is always open, hydraulic fluid will enter the different oil drain, and then through the oil pressure to push the cylinder piston, piston drives the piston rod, piston rod drive mechanism.In this way, mechanical motion is controlled by controlling the current of the electromagnet.


1. Direct acting solenoid valve

Principle: When electrified, the electromagnetic force generated by the electromagnetic coil will lift the closing part from the seat and the valve will open.When the power is cut off, the electromagnetic force disappears, the spring presses the closing part on the seat, and the valve is closed.

Features: it can work normally in vacuum, negative pressure and zero pressure, but the diameter is generally not more than 25mm.
