    Abstract: A fuel-isolation system includes a valve body that defines a flow passage that extends from an inlet to an outlet, a rupture diaphragm in the flow passage and fluidly sealing the inlet from the outlet, and an actuator situated adjacent the rupture diaphragm. The ruprture diaphragm is integral with the valve body. The actuator includes a plunger that is configured to move and cause breach of the rupture diaphragm and thereby fluidly connect the inlet and the inlet.

    Abstract: A system for the control of an indirectly heated gas turbine comprising a primary system of controlling the temperature of heated compressed gas entering the expander, and an independent secondary system which includes a safety valve for instantaneous release of heated compressed gas to the atmosphere. The primary system controls system gas temperature and power output by modulating a flow of unheated compressed gas which bypasses the heat exchanger and mixes with the heated gas leaving the heat exchanger to produce a lower temperature gas entering the expander. The secondary system provides a backup means of overspeed prevention, and includes a safety valve to instantly discharge to the atmosphere hot compressed gas upstream of the expander by being responsive to the speed of the turbine. The safety valve includes a frangible membrane clamped between parallel flanges within the ducting, and further includes a dagger assembly for rupturing the membrane.

    Abstract: Safety device for limiting the pressure of a fluid, having at least one hollow modular member, which is open at both ends, a diaphragm closing one end, and a knife mounted within the modular member facing the diaphragm at a regulatable distance from it. The device also has a piston for making the knife strike the diaphragm in order to bring about bursting before this would be done by deformation of the diaphragm under the effect of a given pressure. The knife may have a pointed central lip bordered by two leading lips so as to reliably bring about bursting of the diaphragm.

    Abstract: A safety pressure relief device is provided for the venting of fluid pressure between first and second pressure zones. The relief device includes a first rupture disk having a flexible sealing membrane located on one side thereof, and a knife means located on the other side of the first rupture disk. The first rupture disk includes a plurality of arcuate slots circumscribing a substantially circular blowout portion. The knife means includes a circular cutting blade located radially inward of the arcuate slots. Upon rupture of the first rupture disk, due to excess pressure in the second pressure zone, the substantially circular blowout portion passes through a circular opening in the knife means, allowing the flexible sealing membrane to contact the cutting blade and be severed thereby. Alternative embodiments add a second rupture disk to relieve excess fluid pressure from the first pressure zone to the second pressure zone.

    Abstract: The valve assembly has inlet and outlet members with valve elements disposed between the two members. The valve is a resilient membrane having one or more through holes. When there is no pressure differential across the valve, the hole walls in the membrane collapse inwards closing off the valve against liquid flow. At or above a threshold pressure differential across the valve, the membrane is stretched which opens up the hole or holes to allow the passage of liquid.

    Abstract: Improved burst disk-type pressure responsive valve assemblies (20, 184) of the pressure relief and shutdown variety are provided which utilize frangible burst disks (30, 204) which largely determine the set point pressures for the valves. The assemblies (20, 184) include a housing (22, 186) having an inlet (24, 188), an outlet (26, 190) with a valve seat (28, 192) therein. The housing (22, 186) also supports a frangible burst disk (30, 204). An actuating unit (32, 210) within the housing (22, 186) includes a shiftable, pressure responsive piston (78, 212) supporting a valve stem actuator rod (82, 214); the rod (82, 214) is operatively coupled with a disk actuating element (84, 216) located adjacent a face of the rupture disk (30, 204). When an overpressure is sensed at the inlet (24, 188), the actuating unit (32, 210) serves to burst the disk (30, 204), allowing the piston (78, 212) to move relative to the valve seat (28, 192) to establish or close communication between the inlet (24, 188) and outlet (26, 190). The valve assemblies (20, 184) can be easily repaired or retrofitted in the field, without the need for extensive dismantling of conduits or the like. Use of disks (30, 204) which rupture during valve operation affords a visual indication of valve operation and permits fabrication of high capacity, long stroke length valves.

    Abstract: 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.

    Abstract: A conventional rupturable curved disc in a pressure relief valve for high pressure cylinders serves as one plate of a capacitor. A curved segmented disc, alterable in curvature in response to deformation of the adjacently located curved disc, serves as the other plate of the capacitor. The segmented disc accommodates and conforms to the normal expected deformation of the curved disc, which deformation is due to repeated fill cycles of the cylinder, without altering the maximum and minimum capacitance during each cycle. The segmented disc physically bears against a translatable electrically conductive plunger element. The plunger element is electrically connected to an impedance variation sensing circuit, which circuit senses and provides an output signal responsive to a change in the capacitance between the curved and segmented discs during each cycle; such output signal reflects the actual pressure, and hence state of fill, of the cylinder.
