The water with the working principle of pneumatic valve

water solenoid pneumatic valve has closed cavity, in a different location to open a hole, each hole leads to different tubing, cavity pneumatic valve is among, both sides are two electromagnets, which face the magnet coil electricity pneumatic valve will be attracted to which side, by controlling the movement of the pneumatic valve body to blocked or leakage of 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. So that by controlling the electric current of the electromagnet to control the mechanical movement.
the pneumatic valve for the second time the guiding type pneumatic valve solenoid pneumatic valve, its structure is mainly composed of pneumatic valve and main valve guide, the main pneumatic valve USES rubber sealing structure. , often activity core sealed guide pneumatic valve, pneumatic valve cavity pressure balance, the main pneumatic valve mouth closed. When energized coil, core activity on the absorption, electromagnetic force is generated the homing pneumatic valve cavity medium pneumatic valve leakage, to generate differential pressure, the diaphragm or pneumatic valve cup was quickly master pneumatic valve mouth open, pneumatic valve is a pathway. Disappear, when the coil power, magnetic activity core reset, close the pneumatic valve guide, guide pneumatic valve and main valve cavity pressure balance, pneumatic valve is closed.
