Explosion-proof type: It is not easy to produce electric isolation, sparks and risky ultra-low temperature when everything is in normal operation. It will further accept the steps of maintenance in the structure and develop the safety and firmness of weaponry and equipment.

    Explosion-proof type: When all weapons and equipment are set up in normal operation, the components that can produce sparks and electric isolation are placed in the flameproof casing. The flameproof casing can accept the working pressure of the outside explosion without being destroyed, and can be inspected and repaired. When the flame vapor outside the mouth spreads widely through the gap, the kinetic energy is reduced, and the vapor outside the shell is lacking to explode.

    Intrinsically safe type: Set the external power supply circuit of weaponry and equipment. Under standard preconditions, the electric spark and thermoelectric effect produced by all normal things or standard problem shapes cannot eliminate explosive confounding.

    Positive pressure type: The gas stove solenoid valve manufacturer persists in external maintenance. The working pressure of the gas is higher than the surrounding working pressure to prevent explosive contaminants from entering the casing or a certain amount of maintenance gas passes through the casing to cause explosive confusion from the outside world The concentration value of the substance drops below the explosion limit.

    Intrinsically safe type: Set the external power supply circuit of weaponry and equipment. Under standard conditions, the electric spark and pyroelectric effect produced by the water heater solenoid valve manufacturer under all normal things or standard problem shapes cannot eliminate explosive contaminants.
