ABSTRACT:
A device for emergently relieving pressure comprises a flexible plate bent downward and having its periphery attached to the inner surface of a hatch coaming, wherein the periphery of the plate is welded to the inner surface of the coaming at appropriate intervals, and the gap between the remaining part of the periphery of the plate and the coaming inner surface is sealed by a sealant.
When a specified pressure exerts on the flexible plate, the plate starts bending back upward. With the upward bending of the plate, the welds between the plate and the coaming are deformed and broken, allowing the plate to be blown off from the coaming. Thus the device, if installed on a fuel tank, serves to relieve the pressure in the tank for the maintenance of safety.
