Abstract
A vibration resistant rupturable pressure relief member for protecting structure subject to vibration from reaching an overpressure condition. The rupturable pressure relief member is comprised of a rupture panel having an elongated concave-convex bulged portion formed therein and having a score pattern on a side thereof which includes an elongated score extending longitudinally across the bulged portion the ends of which connect with additional divergent scores forming opposing V-shapes.
Claims13
A vibration resistant rupturable member for sealingly covering a pressure relief vent of a structure subject to vibration and rupturing at a predetermined pressure level to thereby protect said structure from overpressure comprising a rupture panel adapted to be sealingly connected over said vent having an elongated concave-convex bulged portion formed therein and including a score pattern on a surface of said bulged portion forming lines of weakness therein along which rupture of said panel occurs, said score pattern being comprised of an elongated score extending longitudinally across said bulged portion the ends of which connect with the intersecting ends of pairs of divergent additional scores on said bulged portion which form V-shapes, the length of said elongated score being in the range of from about 2.0 to about 10.0 times the length of the longest of the additional scores forming said V-shapes.
A vibration resistant rupturable member for sealingly covering a pressure relief vent in a structure subject to vibration and sudden internal pressure and temperature increases and rupturing at a predetermined pressure level to thereby protect said structure from overpressure comprising a rupture panel adapted to be sealingly connected over said vent having a concave-convex bulged portion of substantially rectangular peripheral shape formed therein and including a score pattern on the surface of said bulged portion forming lines of weakness therein along which rupture of said panel occurs, said score pattern being comprised of an elongated score extending longitudinally across said bulged portion with the ends of said elongated score connecting with the intersections of the ends of pairs of divergent additional scores on said bulged portion which form opposing V-shapes, the length of said elongated score being in the range of from about 2.0 to about 10.0 times the length of the longest of said additional scores forming said V-shape.
