    Abstract: A rotary shear valve having three-point stator seating is provided. Three contact points are predetermined between a bottom of the stator and a valve body rim and three clamping pads may also be predetermined. The three clamping pads and the three points of contact between stator and the valve body rim are corresponding and aligned when the rotary shear valve is assembled so that the clamping or compression forces on both sides of the stator directly oppose one another, thereby effectively canceling each other. In one embodiment, the stator includes three contact points on the bottom surface proximate the periphery of the stator to contact the valve rim and a gasket includes three clamping pads proximate the periphery of the gasket web to apply a compression force on the top surface of the stator above the three contact points.

A plug member is disposed in the central chamber and is moveable between an open position, to facilitate fluid flow through the plug valve, and a closed position, to block fluid flow through the plug valve. First and second side segments are disposed between and interlocked to the inlet and outlet seal segments to encircle the plug member. The side segments are tensioned to preload the seal segments against the plug member to prevent the flow of fluid between the seal segments and the plug member.

  • Publication number: 20130341545
    Abstract: A valve cartridge assembly comprises a valve cartridge (9) and a transmission device. A recess (90) is formed on the top of the valve cartridge. The transmission device is provided in the recess (90) of the valve cartridge. A first transmission relationship and a second transmission relationship are formed between the transmission device and the recess (90) of the valve cartridge. The first transmission relationship is established so that the transmission device drives the valve cartridge (9) to rotate axially. When the movement in the first transmission relationship is ended, the relationship between the transmission device and the valve cartridge (9) switches from the first transmission relationship to the second transmission relationship. The second transmission relationship is established so that the transmission device drives the valve cartridge (9) to carry out a squeeze movement, and the squeeze movement enables the valve cartridge to have a moving component at least in an axial direction.

    Abstract: Seal ring assemblies for use with rotary valves and methods to manufacture the same are disclosed. A seal ring assembly is described that includes a ring-shaped seal to be fixed within the rotary valve, where the seal enables the sealing engagement of a control member with a flow control aperture. The seal is compressed between a first seal clamp and a second seal clamp by a compressive force maintained by a plurality of fasteners extending through the seal and fixed to the first and second seal clamps.

    Abstract: A valve seat (30) for a ball valve (1) includes an annular body having a central aperture (36) defining a longitudinal flow channel, a first seating surface (38) for engaging and sealing against a corresponding portion of a fluid conduit and a longitudinally opposed second seating (40) surface for engagement with a valve ball. The first seating surface comprises a convex surface profile. The convex profile of the seat (30) allows the stresses incurred during loading from the valve ball (1) to be widely and evenly distributed throughout the structure of the seat (30).

  • Patent number: 8534642
    Abstract: The specification discloses a seal member for selectively completing a fluid passageway defined between an upstream member and a downstream member separated by an intermediate space, the seal member comprising an elongate stem portion dimensioned to be movably positionable in an opening defined through the upstream member between opposite first and second surfaces thereof, the elongate stem portion having provided at one end thereof a resiliency deformable, radially-extending flange and at the other end thereof a sealing face, and a fluid passageway defined through the stem portion between the flange and the sealing face. The flange is deformable under fluid pressure to increase the area of contact between the flange and the first surface of the upstream member and to simultaneously move the stem portion within the opening defined in the upstream member so as to bring the sealing face into sealing contact with an opposing surface of the downstream member across the intermediate space.

  • Patent number: 8496226
    Abstract: A seal assembly is provided for a rotary ball valve having a top-mounted bonnet, thereby allowing the seal assembly to be installed and removed without removing the valve from the pipeline. In an embodiment, the seal assembly may include a seal ring disposed within the valve interior and biased toward the ball element of the valve. A seal carrier may be disposed between the seal ring and the valve body, and the seal carrier may be removably secured to the valve body by a plurality of bolts disposed in the valve interior. A primary leak path may exist between the seal ring and the seal carrier and a secondary leak path may exist between the seal carrier and the valve body. A bellows seal may prevent fluid flow through the primary leak path, and an auxiliary seal may prevent fluid flow through the secondary leak path.

  • Patent number: 8490945
    Abstract: A valve includes a valve body, a valve element to selectively control flow through the valve, and a seal member and seat member together providing a fluid-tight seal between a valve cavity and a fluid passage in the valve body. A live-loaded biasing member is adapted to apply a live-loaded sealing force to the seat member to bias the seat member toward sealing engagement with the valve element. When the pressure in the fluid passage exceeds the pressure in the valve cavity, an unbalanced passage pressure load biases the seat member toward sealing engagement with the valve element. When the pressure in the valve cavity exceeds the pressure in the fluid passage, an unbalanced cavity pressure load biases the seat member toward sealing engagement with the valve element. The live-loaded sealing force is in parallel with each of the unbalanced passage pressure load and the unbalanced cavity pressure load.

    Abstract: A metallic seal for a 90° valve features a generally rectangular shape in section that defines a chamber open to internal pressure that can enlarge the chamber to enhance the sealing effect. Sealing occurs at discrete locations at portions of the seal that are preferably rounded in shape. Overlapping ends that define the entrance to the chamber also are positioned to minimize excessive deflection and resulting plastic deformation that could close off the entrance to the chamber.
