摘要： A valve for controlling flow of pressurized fluid from a confined area that is operable to relieve an overpressure condition as well as to allow flow of fluid in response to a pressure relief command. The valve including a valve body with a fluid passage therethrough, a reverse buckling rupture disc in the valve body in normally blocking relationship to the flow of fluid through the passage, and a selectively actuatable device carried by the valve body adjacent the convex surface. The actuatable device is operable to disrupt, without puncturing, the disc so as to initiate reversal and rupture of the disc and to permit flow of the pressurized fluid through the passage.

摘要： A reverse acting rupture disc and methods of forming the same are provided. Generally, the rupture disc comprises a bulged portion and a circumscribing flange area surrounding the bulged portion. The bulged portion includes a mechanically formed line-of-opening recess comprising a singular channel. In certain embodiments, the mechanical process by which the recess is formed utilizes a high-speed mill which removes a portion of metal from the bulged portion of the disc without disrupting the substantially uniform metallic grain structure of the metal adjacent the channel.

摘要： A metal reverse buckling sanitary rupture disc (12) is provided having a central bulged section (16) in which the convex surface of the bulged section (16) is relatively smooth and of substantially uninterrupted configuration. A small segment region (22) of the central bulged section (16) is strain hardened by plastic deformation causing the segment region (22) to have greater residual stress than the remainder of the central bulged section. When the disc (12) is subjected to an overpressure condition against the convex surface of the bulged section (16) sufficient to effect reversal of the bulged section (16), such reversal commences at the higher residual stress segment region (22) of the bulged section (16).

摘要： This invention relates to a cylindrical holder member (12) for a bi-directional bulged rupture disc (46). The support body of the holder has a rim (14) that supports the rupture disc with the concave surface (48) of the disc facing the holder. The support body is provided with a unitary one-piece, centrally creased cutting element (16) that is of generally V-shaped configuration in plan view. The cutting element has a pair of elongated converging leg components (18,20) with each leg component being connected to and supported by the interior wail surface (22) of the holder body, with each leg component having an arcuate cutting edge (18a,20a). The cutting edges of the leg components merge at the crease (24) in the cutting element to define a central cutting edge peak section (26). The cutting element is positioned in the holder with the cutting edge peak section extending beyond the rim of the support body into the concave area of the disc.
