Do You Know How The Solenoid Valve Works?

Straight through solenoid valve is widely used in industrial manufacturing and more widely in crude oil chemical industry. It can be used to water, gas and neutral gas and other materials and explosion-proof solenoid valve suitable for steam body, liquid button control, but also can be used as a security interlock protection system can not be missing part.
Fire solenoid valve by electromagnetic induction components, oil circuit plate. The electromagnetic induction component is composed of fixed transformer core, transformer core, electromagnetic coil and other components; The oil circuit plate is composed of rotary vane pump core, rotary vane pump sleeve, torsion spring base, etc. When the electromagnetic coil is plugged in or turned off, the operation of the magnetic core will cause the liquid to be disconnected according to the solenoid valve, so as to switch the power supply or change the orientation of the liquid. The key of explosion-proof solenoid valve used in the security interlock protection system has 2 tee, 2 tee and 2 tee. The meaning of 2 is: for explosion-proof solenoid valve is powered on or jump off, for the valve controlled is open or shut down.
The two-position three-way fire solenoid valve is composed of oil circuit plate, valve cover, electromagnetic induction components, torsion spring and sealing structure. The sealing block at the bottom of the moving iron uses the burden of torsion spring to close the air inlet of oil circuit plate. When the power is generated, the electromagnetic coil excitation regulator, the solenoid valve is opened, and the closed block with torsion spring at the upper end of the iron core of the transformer is turned off. The cyclone enters the gate valve from the air inlet, which has the operation effect; When the jumping stops, the magnetic field force fades, the moving iron core moves downward under the action of the torsion spring force and the fixed transformer iron core moves downward, the air outlet is opened, the air intake is plugged, and the power switch is changed due to the loss of air in the gate valve.
The basic principle of 2-position four-way and six-way fire solenoid valves is the same, only the four-way has 1 air outlet, and the six-way has 2 air outlet. Their principle: when there is electric flow through the inductor, resulting in the effect of excitation, fixed core switching transformer core, moving core to promote the valve core and torsion spring, change the part of the rotary vane pump core, and then change the position of the liquid; When the electromagnetic coil jump stop, with the help of the elastic torsion spring to promote the rotary vane pump core, the top back transformer core, so that the liquid according to the original safe flow.
