摘要： A pipe coupling includes two or more partially annular clamp housings, each of which includes two opposing clamp members and one or more tightening elements for tightening the clamp members towards each other in a direction transverse to an axial length of the annular clamp housings. An elastomeric seal assembly is located in seal housings at opposite axial ends of a cylindrical shell. Tightening the clamp members towards each other causes the elastomeric seal assembly to apply a radially-inward clamping force on a pipe or pipes clamped by the pipe coupling. Radial force grippers are spaced about a circumference of each of the annular clamp housings. Radially-inward forces of the radial force grippers create axially-directed forces on the pipe or pipes clamped by the pipe coupling.

摘要： The pipe ball joint includes a casing having a socket portion with a substantially spherical interior surface and a first pipe segment extending from the socket portion. The socket portion has an annular groove disposed adjacent the partially spherical interior surface. A ball pipe section includes a ball segment received in the socket portion of the casing and a second pipe segment extending from the ball segment. A seal assembly is received in the annular groove of the casing and is disposed against the ball segment of the ball pipe section. The seal assembly includes a plurality of nested seal rings that each include a concave face and a convex face.

摘要： A rotary union for use along an incompressible fluid path between a rotating machine component and a non-rotating machine component includes a non-rotating seal carrier including a non-rotating seal element, which together with the non-rotating seal carrier define a net hydraulic surface on an internal side and a net pneumatic surface on an external side. Contact of an incompressible fluid under pressure with the net hydraulic surface creates a closing force, and contact of a compressible fluid under pressure with the net pneumatic surface creates an opening force.

摘要： A grooved joint adapter includes a cylindrical body having an insertion port formed in one end, a groove formed in an outer peripheral surface of the other end, a guide portion formed on an interior thereof, first coupling portions on both outer surfaces thereof, and a fixing portion protruding from an inner peripheral surface thereof. A pipe socket has second coupling portions on both outer surfaces and a protrusion formed on one surface. A pressure ring is disposed on an insertion port side and has both ends separated from each other. A stopper ring is disposed inside of the guide portion, and has both ends separated from each other and one or more wedge sawteeth on an inner peripheral surface. A rubber ring is disposed inside of the cylindrical body, and has an uneven portion on an inner peripheral surface and a stopper portion protruding inward.

摘要： High-pressure cryogenic fluid conduits that deliver high-pressure cryogenic fluids from a first point to a second point. This high-pressure fluid conduit has a safety feature that is activated when the high-pressure cryogenic fluid conduit fails due to exposure to a predetermined force. The safety feature is activated by the fracture of an annular ring that is positioned at either end of the high-pressure fluid conduit and is calibrated to fracture when exposed to the predetermined force. Fracture of the annular ring closes valves at each end of the high-pressure fluid conduit, thereby stopping the flow of high-pressure fluid from the high-pressure fluid source as well as the escape of high-pressure fluid from the high-pressure fluid container.

摘要： A hydraulic connecting bush for correcting hydraulic lines for hydraulic circuit-breaker drives, having a hollow cylindrical main body with at least two annular grooves, extending circumferentially on the main body outer cylindrical surface and having sealing rings inserted therein, the main body being made of a material having a first elasticity modulus. The bush may be configured for overlapping insertion in hydraulic lines to be connected, in contact with each other at end faces, the hydraulic lines being made of a material having a second elasticity modulus, a gap forming between, the main body and the hydraulic lines, such that if the first elasticity modulus is less than the second elasticity modulus, and an internal pressure is applied, the main body expands more than the hydraulic lines and closes the gap in the region of the sealing rings.

摘要： In one example, a fitting assembly including a first fitting, a second fitting, and a seal positioned between the two fittings is disclosed. The first fitting includes a first product contacting sidewall and a first sealing face and the second fitting is coupled to the first fitting and includes a second product contacting sidewall and a second sealing face. The seal is positioned between the first and second sealing faces and includes a radially curved outer surface forming an exterior edge of the seal and a tail extending radially inwards from the radially curved outer surface, where the tail forms an interior edge of the seal that defines an opening through the seal. As connected, the first product contacting sidewall is substantially coplanar with the second product contacting sidewall and the seal seals a connection gap between the two sealing faces.

摘要： A ring-shaped gasket for making high-purity fluid pathway connections between opposing fluid delivery apparatus elements having at least one simple flat surface in contact with the gasket. The face of at least one apparatus element typically has a circular counterbore depression to receive the gasket, but is not required. The gasket has a body, pierced through by a hole creating a fluid pathway and defining a radial inner surface, and additionally having a radial outer surface, a first axial end surface and a second axial end surface. At least one of the first and second axial end surfaces has a stress concentration feature radially adjacent to a gasket sealing region, the sealing region constructed to be in contact with a face surface of a corresponding fluid conduit port. The stress concentration feature may be a groove or a plurality of cavities disposed adjacent the gasket axial end surface sealing region.

摘要： A piping hose connector adapter can be employed as a stand-alone connector or integrated into a valve or fitting. The adapter can comprise a substantially cylindrical body having inner and outer walls, with a plurality of ledges extending radially outwardly from the outer wall and forming grooves therebetween. O-ring members can be inserted in one or more of the grooves. The adapter can be secured at one end to a fitting, and at the other end to a hose using a pressure applying device that can malform the hose around the outer surface of the adapter so as to compress the o-ring member.
