Pressure surge resistant rupture disk assembly

摘要

The present invention provides a pressure surge resistant rupture disk assembly adapted to be sealingly clamped across a pressurized fluid containing passageway. The assembly basically comprises first and second rupture members having predetermined rupture pressures and means disposed between the first and second rupture members for providing a space for containing pressurized fluid within the assembly and for supporting the second rupture member against the first rupture member during a momentary pressure surge. The second rupture member faces the pressurized fluid and has at least one opening therein for allowing a restricted pressurized fluid flow therethrough.
