20080296848 | ANNULAR SEALING MEMBER WITH ENHANCED HOOP STRENGTH - Apparatus and method for providing a sealing member with enhanced hoop strength. In some embodiments, a valve assembly includes a piston and first means for establishing a fluid-tight seal when the piston is in a closed position and for preventing a blow out condition when the piston is transitioned to an open position. In other embodiments, a sealing member is characterized as an endless annular ring which extends about a central axis, the sealing member comprising an elongated circle cross-sectional shape while the sealing member is maintained in an uncompressed state. In other embodiments, a method comprises extruding a sealing material through an extrusion assembly to form an endless annular ring which extends about a central axis, the extrusion assembly imparting a desired amount of curvilinearity along a longitudinal length of the material to form an orthogonal seam when a leading and trailing edge of the material are adjoined. | 12-04-2008 |
20100263738 | Pressure Equalization Assembly for a Liquid Storage Vessel - A vapor pressure equalization assembly having an underpressure relief assembly and an overpressure relief assembly in fluidic communication with the vapor space of a liquid storage tank (vessel). The underpressure and overpressure relief assemblies each have movable pistons sealingly engageable with respective sealing members, and biasing members which exert respective biasing forces to maintain the pistons in sealing engagement with the sealing members. A predetermined underpressure or overpressure differential between the vapor space pressure and atmospheric pressure will cause one of the pistons to open fluidic communication of the vapor space to equalize the vapor space pressure with that of the surrounding atmospheric pressure. | 10-21-2010 |
20100288960 | NON-SIMMER RELIEF VALVE - A relief valve assembly to relieve overpressure of a pressurized fluid. In accordance with some embodiments, the assembly comprises a housing with an inlet and an outlet to form a conduit for a pressurized fluid. A normally closed valve member is axially displaceable within the housing to engage a valve seat to prevent a flow of the pressurized fluid along the conduit. A biasing member applies a bias force to the valve member to retain the valve member against the valve seat. A piston within the valve member contactingly engages the pressurized fluid. A mechanically collapsible member resists axial movement of the piston responsive to said contacting engagement of the pressurized fluid. The piston and collapsible member decouple the bias force supplied by the biasing spring member upon the valve member from a force upon the valve member applied by the pressurized fluid, thereby maintaining a bubble-tight seal. | 11-18-2010 |
20110272615 | Valve Assembly with Annular Sealing Member Having Elongated-Circle Cross-Sectional Shape - Apparatus for controlling a pressurized fluid. In accordance with some embodiments, a valve assembly includes a piston moved between closed and open positions. A sealing member is disposed within an annular recess of the piston and characterized as an endless annular ring extending about a central axis of the piston. The sealing member has an elongated circle cross-sectional shape when the sealing member is in an uncompressed state prior to installation in said recess. The cross-sectional shape is defined by parallel top and bottom surfaces having a length L in a direction perpendicular to and intersecting the central axis, and having opposing inner and outer surfaces of a radius R, the inner and outer surfaces respectively facing toward and facing away from the central axis, and wherein the dimensional value of L is at least five times greater than the dimensional value of R. | 11-10-2011 |
20110278291 | Protection Cap Assembly with Leak Detection Capability for a Pressiruzed Valve - A protective cap assembly for a pressurized valve adapted to detect a leak therethrough. In accordance with various embodiments, the cap assembly includes a body adapted for placement in fluid communication with the valve, and a sensory indicator supported by the cap assembly body to provide human sensory indication of pressurized fluid leaking from the valve in its closed position. In various embodiments, the sensory indicator can be a whistle that makes an audible sound, a light emitting device that emits a visible light, or both. In further embodiments, the cap assembly body can be coupled to the vent conduit via a tether, and ejected responsive to exhausted pressurized fluid when the valve transitions to the open position. The displaced cap assembly body serves as a visual indication that the valve has opened. | 11-17-2011 |
20120037243 | Pressure Equalization Assembly for a Storage Vessel - Apparatus for equalizing pressure within a vapor space of a storage vessel. In accordance with various embodiments, a pressure equalization assembly has a base housing member adapted to be mounted to a tank adjacent a tank aperture in fluidic communication with a vapor space of the tank. A canister assembly is adapted for removable engagement with the housing member between a closed position and an open position. The closed position establishes a fluidic seal interface between the housing member and the canister assembly. The open position provides user access to the vapor space through the tank aperture. The canister assembly further has a compound seal assembly with first and second pistons biased against corresponding first and second annular seal members while the canister assembly is in both the closed position and the open position. A third annular seal member is disposed between the canister assembly and the base housing member. | 02-16-2012 |
20150276063 | Flow Control Shutoff Valve - A normally open flow control valve includes a housing having an inlet port, an outlet port and an interior passageway with a valve seat. A moveable valve member has a sealing head supported for rotation by a cantilevered arm. The sealing head has a sealing member adapted to establish a fluidic seal against the valve seat in a closed position. A biasing member applies a biasing force to the valve member to bring a contact surface of the valve member into contacting engagement with a distal end of a projection pin in an open position. When a flow rate of a pressurized fluid at the inlet port exceeds a selected threshold, impingement of the pressurized fluid against the sealing head rotates the valve member from the open position to the closed position. | 10-01-2015 |
