PERFORATED RUPTURE DISK ASSEMBLY

摘要

An improved pressure relieving rupture disk assembly (10) is provided which includes a rupture disk (20) having at least one perforation (26). The perforation at least partially defines a blow-out part in the rupture disk which opens and relieves pressure when the perforation is sealed and a pressure differential of predetermined magnitude is exerted on the rupture disk. A sealing member (24) is positioned over the perforation in the rupture disk for sealing the perforation when a pressure differential is exerted on the rupture disk.
