ABSTRACT:
A rupture disc apparatus comprises a rupture disc holding cartridge and a fixed receptacle for receiving the cartridge. The receptacle is positioned in a vent so as to communicate on opposite sides thereof with the vent. The cartridge is removable from and replaceable into the receptacle when no pressure exists within the vent so as to position the rupture disc to block passage of fluid through the vent when the disc is unruptured. A first of the receptacle or cartridge includes circumferential seating rings on opposite sides thereof and the other of the receptacle or cartridge includes seats for the rings. The seats and rings are positioned adjacent to the vent. The rings are urged into locking position in the seats by pressure from within the shaft and are manually removable when substantially atmospheric pressure exists within the vent.
