First, the structural characteristics 

Explosion vent valve by the body, burst membrane, support, valve cover, hammer and other components. Burst membrane installed in the middle of the holder, with the valve body bolted. When the system overpressure, rupture membrane rupture. Instant relief, the valve cover pops up under the action of gravity. The valve in the replacement of burst membrane need to lift the valve body and the holder. Bursting membrane by the user based on their own characteristics of the process.
