What is the role of explosion-proof solenoid valve
Explosion-proof solenoid valve used in Europe and the extremely strict explosive-proof grade standard, the standard of explosive-proof grade nine big division, from the flameproof, the Ann model, the Ann model, positive pressure, oil filled, sand mold filling, no spark, encapsulation, type air to air tightness, explosion-proof solenoid valve in the gas, petrochemical, metallurgy, mining and other industries has a very in-depth application.
Why explosion-proof: explosive material: many workplace will produce some combustible materials.
Under the coal mine well, about two-thirds of the sites exist explosive substance;
In chemical industry, about 80% or more of the production workshop area there is explosive material.
Oxygen: oxygen in the air is everywhere.
Light source: electrical instrumentation is used in great quantities in the production process, all sorts of friction spark, spark mechanical wear, spark and high temperature is inevitable, especially when the instrument, electrical failure occurs.
Many industrial field explosion conditions objectively.
When explosive when mixed with oxygen concentration in the explosion range, if any explosion source, will be an explosion.
So take explosion protection is very necessary.
