An explosion vent (10) for covering an opening (12) in an enclosure (14) subject to the build-up of pressure is disclosed. The explosion vent includes a peripheral flange (16) configured for attachment to the enclosure around the opening, a pressure relief panel (18) positioned within and hingedly connected to the flange, and a plurality of connectors or rupture tab assemblies (19) connecting the unhinged portion of the pressure relief panel to the flange. The connectors break when the enclosure is subjected to pressure build-up for permitting the panel to shift outwardly from the enclosure for uncovering the opening in the enclosure. Rivets (72) are provided for attaching the rupture tab assemblies (19) to the pressure relief panel (18) which function to provide additional panel support and minimize localized bending of the rupture tabs (21) forming a part of assemblies (19) when the explosion vent is subjected to vacuum conditions, but do not interfere with rupture of the tabs and opening of the panel at a relatively low burst pressure. The pressure relief panel has a plurality of domed sections (46,48,50,52) presenting at least one valley defining bridge (54,56,58) therebetween. The domed sections and bridges cooperate to stiffen the panel so that it more uniformly distributes force on the connectors, causing all of the connectors to break at approximately the same time so that the panel more consistently opens at a selected burst pressure level.

[ We claim:] [1.] An explosion vent for covering an opening in an enclosure, said explosion vent comprising:a peripheral flange configured for attachment to the enclosure around the opening;a pressure relief panel positioned within and hingedly connected to said flange for covering and substantially sealing the opening when the enclosure is subjected to normal operating pressures and for shifting outwardly from the enclosure for at least partially uncovering the opening when the enclosure is subjected to a build-up of pressure of a pre-determined magnitude; anda plurality of connectors for connecting said panel to said flange and configured for breaking when the enclosure is subjected to the pre-determined magnitude of pressure build-up for permitting said panel to shift outwardly from the enclosure for uncovering the opening in the enclosure;said pressure relief panel having a plurality of domed sections defining at least one bridge therebetween for stiffening said panel for more uniformly distributing force on said connectors when the enclosure is subjected to the pre-determined magnitude of pressure build-up.
