摘要： An inverting, rupturable, pressure relieving apparatus includes a structure having a wall for containing pressurized fluid and an asymmetrical indentation in the wall. The indentation has a base connecting the indentation to the wall, a protuberant side for contacting the pressurized fluid, a recessed side opposite the protuberant side, and an axis about perpendicular to the base and extending through the center of the indentation at the base. The asymmetry of the indentation creates an inversion initiation face in the indentation having a smaller angle with the base and less resistance to inversion than the remainder of the indentation.

摘要： The present invention is directed to pressure relief devices and to corresponding pressure relief assemblies that have improved vacuum resistance, improved fragmentation resistance, and/or improved burst control while maintaining low mass. The pressure relief device includes a substantially flat flange section and a domed section. The domed section may include a transitional line that defines a change in the shape of the domed section. The pressure relief device may also include a bracket for securing or aligning a domed section to a flange section. The pressure relief device may further include a stress distribution feature that is disposed transversely to a line of weakness in the domed section. The pressure relief assembly may include a fastener having a wire that is configured to break and release the pressure relief device when subject to a predetermined tensile load.

摘要： The present invention provides an improved rupture disk apparatus and manufacturing method. The apparatus includes a rupture disk having at least one area of weakness formed by the displacement of material through a partial shearing motion. The weakened area is capable of withstanding pressure cycling because the rupture disk flange acts to support the weakened area during use. The apparatus further includes a safety member adjacent to the rupture disk on the outlet side to ensure opening, the safety member having at least one rupture-initiating, stress-concentrating point positioned to contact the rupture disk weakened area.

摘要： Rotatable valve assembly includes a mounting mechanism for rotatably mounting a valve in a housing. The mounting mechanism includes a shaft having an outside end extending through the housing. A conversion mechanism converts fluid pressure in the housing into torque exerted on the shaft. A release mechanism is located outside the housing for preventing rotation of the shaft and valve when the torque exerted on the shaft is below a selected magnitude. A linearizing mechanism converts the forces exerted on the release mechanism by the shaft into a linear force. The release mechanism allows the shaft to rotate when the torque exerted on the shaft and the linear force exerted on the release mechanism exceeds a selected magnitude. A seal is provided for sealing the gap between the valve and the housing in the closed position of the valve. The seal includes a support edge sealingly secured to the housing, a sealing edge extending inwardly from the support edge into contact with the valve circumference in the closed position of the valve, and a seal body connected between the support edge and the sealing edge and spacing the sealing edge axially towards the inlet face of the valve from the support edge.

A release mechanism is located outside the housing for preventing rotation of the shaft and valve when the torque exerted on the shaft is below a selected magnitude. The release mechanism allows the shaft to rotate when the torque exerted on the shaft exceeds a selected magnitude. A seal is provided for sealing the gap between the housing and the valve in the closed position. The seal has a first portion secured to the housing on a first side of the rotational axis of the valve, a second portion secured to the valve on a second side of the rotational axis, a first transitional portion coinciding with the rotational axis, and a second transitional portion coinciding with the rotational axis. The seal is unsecured to the valve or the housing and the transitional portions so that the seal may flex in the transitional portions as the valve rotates between the closed position and the open position. The first and second portions of the seal define a seal plane in the closed position of the valve and the second portion of the seal moves out of the seal plane with the valve when the valve is moved out of the closed position.

摘要： An improved pressure relieving rupture disk assembly is provided which includes a rupture disk having at least one perforation therein. The perforation at least partially defines a blow-out part in the rupture disk which opens and relieves pressure therethrough when the perforation is sealed and a pressure differential of predetermined magnitude is exerted on the rupture disk. A sealing member is positioned over the perforation in the rupture disk for sealing the perforation when a pressure differential is exerted on the rupture disk.

摘要： Apparatus for preventing fragmentation of a rupture disk during pressure relieving rupture and fluid flow through the ruptured disk includes a rupture control assembly for rupturing the disk into a petal having a body and a base for retaining the petal to the rupture disk; protrusions extending from opposite sides of a housing adjacent the rupture disk for retarding motion of generally opposed edges of the petal as the petal is forced away from the ruptured disk and thereby bending the body of the petal into a channel shape; and a protuberance in general alignment with and spaced away from the base of the petal for impacting the channel-shaped body of the petal as the petal is forced away from the rupture disk and converting the kinetic energy of the petal into deformation of the channel-shaped body in order to prevent severance of the base of the petal from the rupture disk.
