ABSTRACT:
A device for emergently relieving pressure comprising a thin plate having its peripheral portion curved so that its central portion protrudes downward, the peripheral portion being welded to the inner periphery of a hatch coaming provided in a fuel tank, a stiffening plate laid on the central portion of the thin plate, a support beam disposed under the thin plate and extending across the coaming, and a rupture bar connecting the laminate of the thin plate and stiffening plate to the support beam, the rupture bar being adapted to be ruptured before the weld between the peripheral portion of the thin plate and the inner periphery of the coaming is broken.
The device permits accurate release of any abnormal pressure developed in the tank and thus assures the safety of the tank.
