Scored reverse buckling rupture disk assembly.

摘要

A scored reverse buckling rupture disk assembly (10) comprising a reverse buckling rupture disk (22) having one or more scores (42) on a surface thereof forming lines of weakness which define a blow-out portion (32) connected by a hinge area (36) in the rupture disk. An annular rupture disk support member (34) is positioned adjacent the concave side of the rupture disk, and a supporting member (50), for preventing the blow-out portion from fragmenting or tearing away from the rupture disk at the hinge thereof, is disposed within the concave recess (40) in the rupture disk.
