摘要： An actuated valve system operates (open/close) automatically under overpressure condition. The system includes an on/off valve assembly, a spring actuator assembly configured to actuate the on/off valve assembly to open or close a path for the pressurized fluid, a lock mechanism with one locking yoke and two rotatable locking handles, a collapsible pin type pressure sensing assembly configured to trigger the action of the spring actuator assembly, and a pressure sensing line. The collapsible pin type pressure sensing assembly includes a body, a plunger with two stems, one of which is rigidly connected with the locking yoke, and a collapsible pin, which mechanically fails when the fluid pressure reaches the predetermined level. When the collapsible pin fails, the plunger moves together with the locking yoke, and the locking yoke loses its restriction to the motive element of the spring actuator assembly, and thus trigger the operation of the actuated valve system.

摘要： An adjustable release pressure relief valve including a housing having an inlet and a relief outlet connected by a fluid flow passageway, the inlet fluidly connectible to a work string. A head is sealingly disposed within the passageway between the inlet and relief outlet closing the fluid flow passageway between the inlet and relief outlet. An elongate buckling rod supports the head and is bucklable at a predetermined load thereby permitting sliding of the head from between the inlet and a relief outlet and opening the fluid flow passageway. A lateral support projection is extendable within the housing to buttress the buckling rod along the longitudinal length of the buckling rod thereby increasing the load at which the buckling rod is collapsible.

摘要： The present invention relates to safety mechanisms for high-pressure fluid delivery systems. Particularly, the invention relates to a breakaway device which prevents uncontrolled “whipping” of the conduit ends upon a rupture. A heat dissipating coupling, permitting operation of the conduit system at desired temperatures, is also included, as is a breakaway device provided with such a heat dissipation feature.

摘要： 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.

摘要： A valve activation assembly which mechanically collapses a collapsible member, such as a buckling pin, in response to both overpressure and underpressure conditions of a pressurized fluid. A retention member retains the valve member in a selected position with respect to the fluid, such as an open or closed position. A piston assembly is configured to mechanically collapse the collapsible member both when a fluidic pressure upon the piston assembly exceeds a first level, and when a fluidic pressure upon the piston assembly falls below a second level. Upon collapse of the collapsible member, the valve member releases the valve member, allowing the valve member to move to a different selected position (such as closed or open, respectively). A third piston member and a biasing member thereon can also be utilized. In some embodiments, a fluid is preferably held in compression between selected piston members.
