摘要： A ball valve assembly has a lower support, an upper seat, a spherical ball, and linkages for rotating the ball. The lower support has a spherical support surface for the ball. The lower support also has a pair of guides for maintaining alignment of the ball and seat to prevent contact with the linkages. The upper seat has a skirt with a spherical inner surface having grooves for contacting the ball. The skirt and grooves seal and ensure alignment of the ball. The grooves also assist in the retention of lubricant to reduce friction. An optional insert is located in the skirt for low pressure sealing from below and above. Finally, the skirt has a pair of openings to provide relief for the operating links, and flat structures against which the guides of the lower support may restrain rotation of the upper support.

摘要： A ball valve is provided including coupled outer casing elements adapted to enclose a rotationally movable valve body having an axial flow passageway therethrough. An annular casing groove having an anular seal member mounted therein is located adjacent each of the opposite ends of the flow passageway for sealingly engaging the movable valve body. Each of the annular casing grooves includes an annular casing wall projecting toward the movable valve body, and each of the seal members includes a flexible leg extending between its associated casing wall and movable valve body. A first surface of each flexible leg engages the movable valve body and a second, opposed surface of each leg is spaced a predetermined distance from its associated casing wall to accommodate a flexion of the flexible leg. Each of the seal members has a secondary sealing surface extending from the first surfaces thereof, and the secondary surfaces are spaced from the movable body a distance less than the foregoing predetermined distance. A spirally wound resilient member is carried in a recess in each of the seal members to bias the flexible legs into sealing engagement with the movable valve body and to urge the seal members into their associated annular casing grooves. Each of the annular casing walls also provides a further sealing surface adapted to engage the movable valve body upon failure of the seal members and axial displacement of the movable valve body toward the annular casing wall.

摘要： The specification discloses a flange valve having a metal valve body with a longitudinal central passage therethrough and annular flanges extending outwardly from the ends thereof. A truncated ellipsoid valve member is located in the central portion of the passage, the ellipsoid member having major and minor axes and being truncated at the opposite ends of the major axes. An aperture is formed through the ellipsoid member along the major axis. Annular resilient seats are disposed on opposing sides of the valve member to provide sealing between the interior of the valve body and the exterior of the valve member. A pair of removable annular liners are dimensioned to closely fit within opposite ends of the central passage of the valve body and include end portions abutting the resilient seats. The liners are constructed from non-corrosive material to prevent corrosion of the valve body. A handle is provided to rotate the valve member between open and closed positions, the major axis and the aperture being aligned with the passage in the open position and the seats being deformed by the valve member in the open position to provide improved sealing. A wear detector is provided in the walls of the valve body in order to provide an indication of when the liners wear to a predetermined degree.

摘要： A valve comprising a valve body in which a ball valve is centered between two annular seals. The seals are made from an elastic material like rubber and have a thin layer of Teflon on the sides facing the ball valve. The seals are specially shaped to provide for a low seal-loading pressure and to seal at the upstream side of the valve. A spring loaded handle is biased to urge the valve to a closed position.
