摘要： The invention concerns a butterfly valve of a type wherein the elastomer sleeve lines the body bore, and has cheeks which fit into circular recesses provided in the two parallel radial faces of the valve, the shape of the cheeks and of the circular recesses being such that when the valve is assembled between flanges, the elastomer of the cheeks is pressed into a spare volume in the circular recesses and precludes any creep of the elastomer towards the core of the sleeve.

摘要： A valve device comprising a body (1), a closure member (2) operated by a shaft (3) guided through a neck (4) in the body (1), and a liner (5) provided with a flange (6) extending along part of the length of the neck (4). The sealing contact between the shaft and the bore may be improved by means of a clamping assembly (7, 8, 9) positioned around the flange (6) in a space (10) in the body (1). The size of the clamping assembly (7, 8, 9) is such that it exerts a force on the flange (6) and thereby on the shaft (3). The clamping assembly (7, 8, 9) is radially and/or tiltably movable in said space (10) relative to the body (1). Said device is particularly suitable for butterfly valves for use with corrosive and/or delicate liquids such as liquid chemicals and liquid foodstuffs.

摘要： An arrangement for connecting and disconnecting two pipe sections in a fluid transfer system. Each section includes a butterfly valve with a disk pivotally mounted inside, rotating about a swivel axis between a closed position closing the cross-section of the fluid flow and an open position opening the cross-section of the fluid flow. The swivel axes extend perpendicular to the pipe axis and parallel to each other. The swivel axes of the disks are eccentric relative to the axes of the sections to reduce the space between the disks in their closed position, when the sections are connected. The invention is useful for transferring liquefied natural gas.

摘要： A gasket, which functions as a static radial seal, includes a first sealing ring disposed at a first predetermined distance from a longitudinal axis. A second sealing ring is disposed at a second predetermined distance from the longitudinal axis. The second distance is less than the first distance. The first and second sealing rings are made of metal. A common metal C-shaped casing envelopes the first and second sealing rings. The first and second sealing rings move between a relaxed position prior to installation and an engaged position after installation. The first and second sealing rings are positioned in the casing in the relaxed position and define a line that extends between the centers of the first and second sealing rings. This line is disposed at an oblique offset angle with respect to the longitudinal axis.
