Water solenoid valve

- Nov 03, 2017-

Water solenoid valve has a closed cavity, in different locations have open through-hole, each hole leads to different tubing, the middle of the valve is the valve, the two sides are two electromagnets, which side of the magnet coil body valve will be Is attracted to the side by moving the valve body to stop or leak different drain hole, and the inlet hole is normally open, the hydraulic oil will enter the different drain pipe, and then through the pressure of oil to promote Cylinder piston, the piston and piston rod, piston rod driven mechanical device. This controls the mechanical movement by controlling the electromagnet current.

The valve is a pilot-operated two-way valve, its structure mainly consists of pilot valve and main valve, the main valve adopts rubber seal structure. Standing position, the activities of iron core seal pilot port, valve cavity pressure balance, the main valve port closed. When the coil is energized, an electromagnetic force is generated to pull the movable iron core. The medium in the main valve cavity leaks out of the pilot valve port, resulting in a pressure difference. The diaphragm or the valve cup is promptly lifted. The main valve port is opened and the valve is opened Access When the coil power, the magnetic field disappears, the activities of the core reset, closed pilot port, pilot valve and the main valve cavity pressure balance, the valve was closed.
