Abstract
A pressure relief module, such as a rupture disk module or a burst panel module, is disclosed. A pressure relief module may comprise a first membrane (10) configured to seal an opening of a contained system and configured to burst open when a pressure in the contained system reaches a predetermined burst pressure. A second membrane (20) may be joined to the first membrane to form a membrane interspace (30) with the first membrane. The membrane interspace (30) may be configured to prevent a backpressure in the contained system from changing the burst pressure required to burst open the first membrane (10). A pressure relief module may provide advantages for a low-pressure enclosure and/or to provide temperature stability and/or backpressure stability.
Claims16
A pressure relief module, comprising:
- a primary membrane;
- and
- a secondary membrane;
- wherein the primary membrane has a set pressure, wherein the primary membrane is configured to seal an opening of a contained system;
- wherein the primary membrane is configured to burst open when a pressure in the contained system reaches the set pressure;
- wherein the secondary membrane is joined to the primary membrane to form a membrane interspace between the primary and secondary membrane;
- wherein the second membrane is exposed to a backpressure;
- and
- wherein the membrane interspace is sealed and pressurized, and wherein the pressure within the membrane interspace is configured to maintain the set pressure of the primary membrane in response to an increase in temperature of the primary membrane throughout a predetermined range of operating temperatures.
