The difference between ordinary solenoid valve and anti-riot solenoid valve

Explosion-proof solenoid valves are generally explosion-proof, intrinsically safe, encapsulated, and sand-filled. Therefore, explosion-proof solenoid valves must be used for combustible gases. Common in the chemical industry valve control system and other places.
Explosion-proof solenoid valve is to completely enclose the components of the device that can ignite the explosive gas mixture in a shell. The shell can withstand any joint or structural gap through the shell. The flammable mixture that penetrates into the shell is exploded inside without damage, and it does not It will cause the external ignition of an explosive atmosphere formed by one or more gases or vapours. Parts that may generate sparks, arcs, and dangerous temperatures will all be put into a flameproof enclosure. The flameproof enclosure will make the interior space of the equipment and the surrounding environment. Separated. There is a gap in the flameproof enclosure, due to the respiration of the electrical equipment and gas infiltration, there may be an explosive gas mixture inside.
The difference between ordinary electromagnetic valve and anti-riot electromagnetic valve is reflected in the connection box, the so-called riot refers to the electromagnetic head lock caused by the current fluctuations and other energy conversion is not enough to ignite the corresponding environment gas, said that the simple point is the electromagnetic head movement required energy Exposure to combustible gases is dangerous.
1, explosion-proof solenoid valve has a long working life.
2. Explosion-proof electromagnetic valve working system: It is divided into three types: long-term working system, repeated short-term working system and short-time working system. Explosion-proof solenoid valves are long-term working systems, that is, coils allow long-term power work. For long-term valve opening only short-term closure, you should use normally open solenoid valve. When used in a short-time work system and in large quantities, special orders can be made to reduce power consumption.
3, explosion-proof solenoid valve operating frequency: When the operating frequency is high, the structure should be the best direct-acting solenoid valve, power supply to listen to the preferred exchange.
