First, the product works and uses
Explosion-proof valve is suitable for building materials, metallurgy, chemical industry, electricity and other departments, as a pressure relief explosive gas pipeline equipment for compressed explosive gas, the working temperature 300 ℃, the use of pressure 0.1MPa. The valve is welded steel structure, simple structure, light weight, reliable performance. The valve by the valve body, bursting disc, gland and other components. Mainly from the protection, to prevent the occurrence of safety incidents, belonging to the hydraulic system of the lock, tight measures. When the system pressure is greater than 0.1MPa pressure, the rupture disc ruptures itself to prevent the system from exploding.
