Explosion-proof solenoid valves are all the devices may be lit with explosive gas mixture components enclosed in a shell, the shell can withstand any shell joint surface or structure clearance, infiltrate into the inside of the shell of combustible mixture in the internal explosion damaged, and not caused by outside a gas or vapour formation of explosive environment, a variety of lighting, Parts that may generate sparks, arcs and dangerous temperatures are placed in a flameproof enclosure that separates the internal space of the equipment from the surrounding environment. There are gaps in the flameproof enclosure, which may contain explosive gas mixtures due to respiration and gas penetration of electrical equipment.

The difference between ordinary solenoid valve and riot solenoid valve is reflected in the wiring box. The so-called riot solenoid valve manufacturing means that the current fluctuation caused by the electromagnetic head lock and other energy transformation is not enough to ignite the corresponding environmental gas. The simple point is that the energy required by the electromagnetic head action is exposed to combustible gas.

1, explosion-proof solenoid valve long working life.

2, explosion-proof solenoid valve working system: divided into long-term working system, repeated short-term working system and short-term working system three. Explosion-proof solenoid valves are long-term working system, that is, coil allows long-term energized work. For a long time valve opening only a short time to close the situation, it is appropriate to choose normally open solenoid valve. In short time working system and large batch, can make special order to reduce power consumption.

3, explosion-proof solenoid valve working frequency: action frequency requirements are high, the structure should be preferred direct moving solenoid valve, power supply to listen to the preferred AC.
