摘要： A reverse acting rupture disc is provided having a laser defined electropolished line-of-weakness recess, and an improved method of forming an electropolished line-of-weakness recess in a reverse acting rupture disc that assures full opening of the disc upon reversal. A rupture disc blank is pre-bulged, final bulged, and then provided with a layer of resist material. A laser is used to remove at least a portion of the layer of resist material corresponding to a desired line-of-weakness recess in the concave face of the bulged rupture disc. The disc is then subjected to an electropolishing operation to remove metal from the lased area of the rupture disc, thereby forming a lustrous polished line-of-weakness recess in the disc of desired configuration and of a predetermined depth that is related to material thickness. The electropolished line of weakness is defined by spaced opposed channel portions separated by a central raised crown portion wherein the channel portions are of greater depth than the crown portion. The burst/reversal pressure of the disc having an electropolished line-of-weakness recess may be selectively controlled by varying the pre-bulging pressure on the disc.

摘要： 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.
