Cast Steel Stainless Steel Flanged Connection Explosion-Proof Wave Safety Valve
Product introduction:
FA49H series explosion-proof wave safety valve is a water safety valve that can both eliminate and block water hammer shock waves. It is a product composed of multiple sets of safety valves and has a buffer spring structure, which cannot be achieved by a single safety valve. When a water hammer is formed but does not cause damage, the buffer spring dissolves the water hammer. When the formed water hammer reaches enough to damage the subsequent equipment, the safety valve group takes effect. The pressure inside the valve chamber is discharged from the valve body, and the equipment behind the wave valve is protected from the water hammer impact, ensuring the normal operation of the system and the normal operation of the facilities.
FA49H series explosion-proof wave safety valve is installed at the head of the water supply engineering pipeline and the civil defense system, combining wave blocking and wave attenuation to prevent the water hammer shock wave from entering the system water supply engineering along the pipeline, thereby eliminating the shock wave that damages the water hammer and protecting the normal operation and safety protection of the system facilities.
