Abstract
A pressure relief assembly has a frame having a coupling structure, a valve mounting surface, a valve opening within the valve mounting surface, a vent mounting surface, and a vent opening within the vent mounting surface. The vent opening is functionally parallel to the valve opening. A valve body is sealably disposed on the valve mounting surface across the valve opening. A first detent releasably secures the valve body to the frame. The first detent is configured to release the valve body from the frame upon a minimum pressure differential across the valve opening. A vent is coupled to the vent mounting surface across the vent opening.
Claims20
A pressure relief assembly comprising:
- a frame comprising a coupling structure, a valve mounting surface, a valve opening within the valve mounting surface, a vent mounting surface, and a vent opening within the vent mounting surface, wherein the vent opening is functionally parallel to the valve opening;
- a valve body sealably disposed on the valve mounting surface across the valve opening;
- a first detent ball releasably securing the valve body to the frame, wherein the first detent ball is configured to release the valve body from the frame upon a minimum pressure differential across the valve opening such that at least 85% of the lateral area of the valve opening does not overlap with the lateral area of the valve body in the axial direction;
- and
- a vent coupled to the vent mounting surface across the vent opening.
A pressure relief assembly comprising:
- a frame comprising a coupling structure, a valve mounting surface, and a valve opening within the valve mounting surface, the pressure relief assembly having a first axial end, a second axial end, and a valve airflow pathway extending from the first axial end through the second axial end through the valve opening;
- a valve body sealably disposed on the valve mounting surface across the valve opening, whereby the valve airflow pathway is obstructed;
- and
- a first spring-loaded detent ball releasably securing the valve body to the frame, wherein the first spring-loaded detent ball is configured to release the valve body from the frame upon a minimum pressure differential across the valve opening,
- wherein the valve body is configured toclear the valve airflow pathway upon the minimum pressure differential across the valve opening such that at least 85% of the lateral area of the valve opening does not overlap with the lateral area of the valve body in the axial direction.
A pressure relief assembly comprising:
- a frame comprising a coupling structure, a valve mounting surface, and a valve opening within the valve mounting surface;
- a valve body sealably disposed on the valve mounting surface across the valve opening;
- and
- a first spring-loaded detent releasably securing the valve body to the frame, wherein the first spring-loaded detent is configured to release the valve body from the frame upon a minimum pressure differential across the valve opening,
- wherein the first spring-loaded detent comprises a compression spring disposed in the valve body;
- and a detent engagement surface translatably disposed relative to the valve body, wherein the compression spring is compressed and extends laterally inward from the detent engagement surface.
