Product description
Inclined explosion-proof valve, also called explosion-proof door, is a new type of product that protects the boiler body and flue from being deflated. The steel welded structure is simple in structure, light in weight and reliable in performance. It is mainly composed of valve body, bursting disc, gland, etc. When the system pressure is greater than 0.1MPa, the bursting disc will rupture by itself to prevent the system from exploding. This valve is suitable for building materials, metallurgy, chemical industry, electric power and other fields, as a pressure relief device for compressed and explosive gas pipelines. Mainly play a protective role to prevent the occurrence of safety accidents.
