Abstract
An overpressure protection system (30) for a magazine (10) for storing explosive materials. The magazine (10) comprises a wall (12) which defines an internal chamber (14) for housing the explosive materials, with a first aperture (20) defined in the wall (12). The overpressure protection system (30) is configured to close the first aperture (20). The system (30) comprises a burst disc diaphragm (32) for covering the first aperture (20), and a protective cover (34) for locating outside of the chamber (14) and over the burst disc diaphragm (32). The protective cover (34) is spaced apart from the burst disc diaphragm (32) to form a cavity (38) with an opening (36) for venting fluid from the cavity (38).
Claims18
An overpressure protection system for a magazine for storing explosive materials, the magazine comprising a wall which defines an internal chamber for housing the explosive materials, with an aperture defined in the wall, the overpressure protection system comprising:
- a burst disc diaphragm for covering the aperture;
- a protective cover for locating outside of the chamber and over the burst disc diaphragm, the protective cover being spaced apart from the burst disc diaphragm to form a cavity with an opening for venting fluid from the cavity;
- and
- a mount for fixing the protective cover relative to the wall of the magazine, the mount configured to space the protective cover apart from the burst disc diaphragm, wherein the protective cover is provided as a panel fixed to the mount, the mount comprising a frangible fixture configured to rupture to allow the protective cover to open.
An overpressure protection system for a magazine for storing explosive materials, the magazine comprising a wall which defines an internal chamber for housing the explosive materials, with an aperture defined in the wall, the overpressure protection system comprising:
- a burst disc diaphragm for covering the aperture, the burst disc diaphragm including one or more weakened regions configured to fail at a condition defined as a function of pressure and/or rate of change of pressure;
- and
- a protective cover for locating outside of the chamber and over the burst disc diaphragm, the protective cover being spaced apart from the burst disc diaphragm to form a cavity with an opening for venting fluid from the cavity, the protective cover configured to open at the condition.
An overpressure protection system for a magazine for storing explosive materials, the magazine comprising a wall which defines an internal chamber for housing the explosive materials, with an aperture defined in the wall, the overpressure protection system comprising:
- a burst disc diaphragm for covering the aperture, the burst disc diaphragm including a weakened region configured to fail if a condition is met, the condition defined as a function of pressure and/or rate of change of pressure;
- and
- a protective cover for locating outside of the chamber and over the burst disc diaphragm, the protective cover configured to open if the condition is met, wherein the protective cover includes a panel pivotably mounted by a hinge, such that the panel is in a first position when the aperture is closed, and the panel is in a second position when the aperture is open.
