Title: ROTATABLE PRESSURE RELIEF VALVE ASSEMBLY
Abstract:
A rotatable pressure relief valve assembly is disclosed. The rotatable pressure relief valve assembly may comprise a rotatable plug mounted within a valve body, along with a release mechanism configured to engage with the shaft and hold the plug in a closed position until an opening pressure of the valve assembly is reached. An assembly may include a damper configured to absorb a rotational kinetic energy or a catching mechanism configured to retain the plug in an open position when the plug rotates into the open position. A plug may be wing-shaped or have a mass balanced across a rotatable shaft offset from a diameter of the plug. An assembly may include a buckling pin, torque pin, tensile member or other release mechanism, which may be pre-loaded. A thermal shield also may be provided.
