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.
