1. Brief introduction
Explosion-proof valve is widely used in the sectors such as building materials, metallurgy, chemical engineering and electrical industries as a device to release pressure from the pipes having the compression and explosive potential. Explosion-proof valve is particularly applicable to the system of coal mill and the warehouse for storage of flammable and explosive gas. Explosion-proof valve has simple structure which is composed of the welded steel tube and the explosion-proof valve pieces. When the system pressure is higher than table pressure, explosion-proof valve piece ruptures itself to prevent the system from an explosion and ensure personal and work safety.
