Ordinary solenoid valve and anti-riot solenoid valve is reflected in the difference between the wiring box, the so-called anti-riot that is caused by electromagnetic headlamps current fluctuations and other energy conversion is not enough to ignite the corresponding ambient gas, that simple point is the energy required for the operation of the head Exposure to combustible gas is dangerous.
Explosion-proof solenoid valve is the equipment may ignite the explosive gas mixture of all parts enclosed in a shell, the shell can withstand any joints through the shell or structural gap, penetrate into the interior of the combustible mixture inside the explosion without damage, and not Will cause the external by a, a variety of gases or vapors formed by the explosive atmosphere of the ignition, the possible spark, arc and dangerous temperature parts are placed in the flameproof shell, the Shanghai Hongfeng valve explosion-proof shell to make the equipment internal space Separated from the surrounding environment. There is a gap between the explosion-proof shell, due to electrical equipment respiration and gas infiltration, so that there may be explosive gas mixture.
1, explosion-proof solenoid valve long working life.
2, explosion-proof solenoid valve operating system: sub-long-term work system, repeated short-term working system and short-term work system three. Explosion-proof solenoid valves are long-term work system, that is, the coil allows long-term power work. For a long time the valve is only a short time to close the case, you should use normally open solenoid valve. When used in short-term work and batch and large, can be used for special orders to reduce power consumption.
