The explosion-proof solenoid valve is to enclose all the parts of the equipment that may ignite explosive gas mixture in a shell. The shell can withstand the explosion of the combustible mixture penetrating into the inner shell through any joint surface or structural gap of the shell without damage, and will not cause external explosion by one or more gases or steaming. The ignition of explosive environment formed by gas puts the parts which may produce sparks, arcs and dangerous temperatures into the flameproof housing, which separates the internal space of the equipment from the surrounding environment. There is a gap in the flameproof enclosure. Because of the effect of breathing and gas permeation of electrical equipment, explosive gas mixture may exist in the enclosure.
Advantages of explosion-proof solenoid valve
1. Explosion proof solenoid valve has long service life.
2. Explosion-proof solenoid valve working system: long-term working system, repeated short-term working system and short-term working system. The explosion-proof solenoid valve is a long-term working system, that is, the coil is allowed to work for a long time. For a long time valve opening only a short time closure, it is advisable to use normally open solenoid valve. It can be used for special orders to reduce power consumption when short working hours are large.
3. The working frequency of explosion-proof solenoid valve: When the operating frequency is high, the structure should select the direct solenoid valve, and the power supply should listen to the optimal AC.
