Working Principle Of Explosion-proof Electromagnetic Valve

Working Principle Of Explosion-proof Electromagnetic ValveSep 22,2021

The explosion-proof solenoid valve seals all parts of the device that may ignite an explosive gas mixture in a housing that can withstand any joint or structural gap through the housing a combustible mixture that penetrates the interior of the enclosure may be exploded internally without damage and without causing ignition of an external explosive environment consisting of one or more gases or vapors. The components that may generate sparks, ARCS, and dangerous temperatures are placed in a flameproof enclosure that separates the internal space of the device from the surrounding environment. There is a gap in the flameproof enclosure, which may contain explosive gas mixture due to the suction and gas permeation of the electrical equipment.

The explosion-proof solenoid valve coil shell not only can withstand the explosion pressure of the gas explosion, but also has a blocking effect on the energy transfer of the gas explosion and higher safety performance. It is specially designed for transporting inflammable and explosive medium or special electromagnetic valve series products for explosive dangerous places. Different environment and fluid should choose different explosion-proof grade electromagnetic valve.

How It Works:

The solenoid valve has an airtight cavity with through holes in different positions. Each hole leads to a different oil pipe. In the center of the cavity is a valve with two electromagnets on both sides By controlling the movement of the valve body to block or leak out different oil discharge holes, and the oil inlet hole is always open, the hydraulic oil will enter different oil discharge pipes, and then through the oil pressure to push the piston cylinder, the Piston in turn moves the Piston Rod drives the mechanism. Thus the mechanical motion is controlled by controlling the current of the electromagnet.

Product Features:

1. Explosion-proof solenoid valve long service life.

2. Explosion-proof solenoid valve working system: sub-long-term working system, repeated short-term working system and short-term working system. Explosion-proof solenoid valve are long-term work system, that is, the coil allows long-term electrification work. For a long time to open the valve only a short time to close the case, it is appropriate to choose the normally open solenoid valve. It can be used in short-time working system and large batch, special order can be made to reduce power consumption.

3. Explosion-proof solenoid valve working frequency: When the action frequency is high, the structure should be preferred direct-acting solenoid valve, power supply should be preferred AC.
