Abstract
A pressure relief device is disclosed that is designed to open in response to a pre-determined pressure differential. The pressure relief device includes a panel member, and at least one release mechanism. The release mechanism has a first end, a failure portion configured to fail upon experiencing a predetermined load, and a second end. The at least one release mechanism is configured to hold the panel member against a frame prior to experiencing the predetermined pressure differential.
Claims51
A pressure relief device comprising:
- a panel member;
- at least one release mechanism having,
- a first end,
- a failure portion configured to fail upon experiencing a predetermined load, and
- a second end,
- and
- wherein the at least one release mechanism is configured to hold the panel member against a frame.
A pressure relief device comprising:
- a frame;
- a panel member;
- at least one release mechanism having,
- a first end,
- a failure portion configured to configured to fail upon experiencing a predetermined load, and
- a second end,
- and
- wherein the release mechanism is configured to hold the panel member against the frame.
A method of installing a pressure relief device comprising:
- providing a pressure relief device including:
- a frame;
- a panel member;
- and
- at least one release mechanism having, a first end, a failure portion configured to fail upon experiencing a predetermined load, and a second end;
- mounting the frame to an opening in a pressurized system;
- locating the panel member on an outlet side of the frame;
- and
- connecting the panel member to the frame through the release mechanism such that the failure member is located on an inlet side relative to the panel member.
A method of installing and maintaining a pressure relief device comprising:
- providing a pressure relief device including:
- a frame;
- a panel member;
- and
- at least one release mechanism having, a first end, a failure portion configured to fail upon experiencing a predetermined load, and a second end;
- mounting the frame to an opening in a pressurized system;
- locating the panel member on an outlet side of the frame;
- connecting the panel member to the frame through the release mechanism;
- after the occurrence of a predetermined pressure differential between an outlet side and an inlet side of the panel member, repositioning the panel member on an outlet side of the frame and replacing at least the failure portion of the release mechanism.
