    摘要： A caisson gate valve (10) fitting within an outer casing (12) extending downwardly from a subsea wellhead below the sea floor is disclosed. The gate valve (10) includes a valve body or block (14) having an axial bore or flow passage (16) therethrough and a transverse cavity (18) in body (14) which extends through the body (14) to provide open ends (19) for cavity (18). Covers (60, 66) are mounted over the open ends (19) of cavity (18). A gate carrier (24) has an oval opening (26) which receives a gate member (28) having a gate opening (30) therein for movement between open and closed positions relative to the flow passage (16). A pair of opposed stems or pistons (32, 34) extend from gate carrier (28) for actuation of gate carrier (24) and valve member (28) between open and closed positions relative to flow passage (16). Fluid chambers (36, 38) adjacent pistons (32, 34) provide pressurized fluid for actuation of gate carrier (24) and gate member (28) therein.

    摘要： A gate valve adapted for stem back seating has a stem and bonnet assembly with a rotatable bearing ring to which the stem is releasably fixed during normal gate opening and closing operations. During back seating, the stem is released from the bearing ring and the bearing ring is fixed to the bonnet cap, enabling low torque back seating by rotation of the stem relative to the bearing ring and bonnet cap.

    摘要： A kelly cock valve for a drill rig uses a sliding gate to open and close the flow passage through the drill string. The valve has a body with a longitudinal passage through it. The gate is mounted in the body perpendicular to the flow passage. Pushrods extend from each end of the gate out through bonnets mounted to the body of the valve. The fluid cylinders are mounted on each side of the gate. Each fluid cylinder has a piston with a piston rod extending in opposite directions. The piston rods are connected to a beam that also connects to the pushrod. Hydraulic passages supply fluid to the cylinders to stroke the piston and thus move the gate valve between open and closed positions.

    摘要： A gate valve having a body with a valve chamber therein, an inlet passage through the body into the valve chamber, an outlet passage through the body into the valve chamber, a gate positioned within the chamber and having an opening therethrough, a body sealing surface surrounding the openings of each of the inlet and outlet passages within the passages within the chamber, a seat ring positioned between the gate and each of the body sealing surfaces, means for urging the seat rings against their body sealing surfaces, resilient seals between each seat ring and its body sealing surface near the inner and outer diameter of each ring, means for sealing between the gate and the seal rings, and means for moving said gate in said chamber to close and open flow through said valve. The means urging the seat rings against their body sealing surfaces in one form includes wedges positioned at the side of the gate engaged between the two seat rings and in another form includes springs positioned at the sides of the gate engaged between the two seat rings.
