摘要： A pressure relief valve includes a singular body that encloses a seat and a stationary shim, a poppet, within the singular body, that is forced against a seat by a spring attached to the stationary shim, and a pin inserted into the pressure relief valve body to lock the pressure relief valve into a housing bore. The poppet includes a nose extension that extends into a void enclosed by the seat to provide damping. The seat includes a non-threaded stepped region on its outer surface and the singular body includes a complementary stepped region on its inner surface such that when the seat is fit into the singular body, the stepped region of the seat and the complementary stepped region of the singular body interface with each other to prevent movement of the seat toward the spring. The pin includes a coating to reduce friction and galling.

摘要： An auto-fill type float collar assembly is provided. The float collar assembly of the present invention has at least one curved flapper-style valve, preferably constructed of composite, non-metallic material. Each flapper of the present invention has a substantially 90° range of motion, and is closed via a torsion spring. Each flapper is held in the open (or “auto-fill”), position via an external shifting mechanism passing around, rather than through, the central flow bore of the assembly. A floatable actuation ball can be run with the tool, or pumped downhole, in order to selectively actuate the assembly and close the flappers when desired.

摘要： A valve-closing pressure chamber and a valve-opening pressure chamber are arranged on both sides of a main diaphragm inside an outlet shutoff valve. An upper supply/discharge tube and a lower supply/discharge tube are connected to a housing forming the outlet shutoff valve. The upper and lower supply/discharge tube supply and discharge air to and from the valve-closing pressure chamber and the valve-opening pressure chamber, respectively. An opening end, which is on the pressure chamber side, of each supply/discharge tube is obliquely cut relative to the direction of axis of the supply/discharge tube, which increases the opening area of the opening end. This prevents water present in the pressure chamber from adhering to the opening end of each supply/discharge tube and prevents the adhered water from freezing. As a result, operation performance of the outlet shutoff valve is enhanced.

摘要： The rigid coupling device includes a closure valve extended by a retractable sliding stop member of general tubular shape made from elastically deformable material, having at least one outward radial projection forming a stop against a corresponding inward radial projection of a movable interior body that contains the valve. The stop member has an open end opposite the opening of the cylindrical cavity of one end connecting to the conduit. Simultaneous withdrawal of the interior body and of the valve into the interior body has the effect of causing this open end to contract, forcibly inserting it into the cylindrical cavity of the connecting end in such a manner as to overcome the stop.

摘要： A pipe coupling member for high-pressure fluid such as liquefied hydrogen includes a seal ring having a highly effective sealing function to prevent leakage of the fluid. The seal ring (72) is set in a seal ring setting space (39) defined by a second radial surface (36) and a seal ring setting surface (38) of a first tubular member (20), a forward end surface of a second tubular member (22), and the outer peripheral surface of a valve seat member (24). A forward end portion of the second tubular member (22) is provided with a communication hole (84) radially penetrating the forward end portion. The pressure of the high-pressure fluid on the downstream side of a valve seat surface (52) causes a fluid path in the second tubular member to be communicated with the sealing ring setting space (39) via the communication hole (84) and via a gap between the seal ring setting surface (38) and the outer peripheral surface of the forward end portion of the second tubular member.

An upper supply/discharge tube and a lower supply/discharge tube are connected to a housing forming the outlet shutoff valve. The upper and lower supply/discharge tube supply and discharge air to and from the valve-closing pressure chamber and the valve-opening pressure chamber, respectively. An opening end, which is on the pressure chamber side, of each supply/discharge tube is obliquely cut relative to the direction of axis of the supply/discharge tube, which increases the opening area of the opening end. This prevents water present in the pressure chamber from adhering to the opening end of each supply/discharge tube and prevents the adhered water from freezing. This in turn prevents the opening end of the supply/discharge tube from being closed or the opening area from being reduced. As a result, operation performance of the outlet shutoff valve is enhanced.
