Special structure and purpose :
This series of vent valve by the body, burst membrane, gripper, valve cover, hammer and other components. Burst membrane installed in the middle of the holder, with the valve body bolted. System overpressure, rupture of the rupture membrane, instant pressure relief, the valve cover pops up under gravity reset. The vent valve in the replacement of the rupture membrane when the valve body and the holder must be lifted vertically.
Bursting
membrane owned by the user according to the process characteristics,
mainly for building materials, metallurgy, petroleum, chemical and other
administrative departments.
