    摘要: A top entry trunnion mounted rotary ball valve defining a main valve body having an upstream and a downstream ball seat assembly, the ball seat assemblies further including a soft insert seal, a ball seat, a seat retainer and a plurality of compression springs in between the ball seat and the seat retainer. A guiding groove on a cylindrical surface of each of the ball seats, having a first end and a second end at an axial distance equal to or more than a measure of retraction required so as to get a mechanical clearance to remove or assemble the ball member. Each ball seat is retracted in a recess against a force Fc of the compression springs and the mechanical clearance is created between the ball member and the soft insert seal, to remove or assemble the ball member and or any component from inside the valve body.

    摘要: A valve assembly and associated assembly method includes a housing receiving a valve member for movement between open and closed positions. A packing received around the valve member has at least first and second openings in a sidewall thereof and a third opening that has an original unstretched opening dimension smaller than a cross-sectional dimension of the valve member forcibly inserted through the third opening and thereby enlarges the third opening to a stretched opening dimension. A packing gland engages the packing, and at least one of the packing gland and packing has a non-planar surface that urges the stretched opening dimension of the third opening of the packing toward the original unstretched dimension after the valve member is assembled in the packing.

    摘要: This valve is integrated into a fluid distribution network and enables selective interruption or authorization of the circulation of a fluid. The valve includes a fluid blocking member driven in rotation by an actuator device of the valve and at least one journal, a hollow body inside which the blocking member is mobile and which defines at least one bore for receiving the journal, and a bearing disposed around each journal and inside the bore of the body enabling support of the journal and guidance thereof in rotation relative to the bore, thereby centering the journal. The valve further includes a device for immobilizing and sealing for maintenance the journal relative to the body of the valve. This immobilization device is disposed on the same side of the bearing as the internal volume of the hollow body and is maneuverable via the bearing to go from a non-clamped first configuration to a clamped second configuration in which it immobilizes the journal in the bore and vice versa.

    摘要: The invention relates to a valve assembly which includes at least one, but typically two, balls located along a passage and which balls can be moved between open and closed positions to selectively control the passage of fluid along the passage. The valve assembly includes at at least one end thereof a retaining assembly which allows the effective sealing against one surface of a ball and retention of the same in position. A sealing assembly is also provided when two balls are provided, intermediate the same, which allows effective sealing to be achieved and at least one of the two trunnions which allows each of the balls to be mounted within the valve body is located only internally of the valve body. The components of the valve assembly which are located within the same can in one embodiment all be inserted into and located within the valve body from one common end.

    摘要: A fluid flow control device includes a valve body, a bonnet, a control assembly, and a seal assembly. The valve body defines an inlet portion, an outlet portion, a bonnet opening, and a fluid flow path extending between the inlet portion and the outlet portion. The bonnet is disposed in the bonnet opening. The control assembly is at least partly supported by the bonnet, and includes a ball element disposed within the valve body and rotatable between an open position and a closed position. The valve body defines an internal recess at a location downstream from the inlet portion and adjacent the bonnet opening. The seal assembly is disposed within the internal recess and includes a movable sleeve seal, a retaining device, and one or more sealing elements for preventing leakage between the sleeve seal and the retaining device and/or the valve body.

    摘要: A two-part back cap for a plug valve includes a back cap seal body and a back cap retainer nut. The back cap retainer nut secures the back cap seal body within the plug valve and securely supports the back cap seal body. A gap between an outer periphery of the back cap retainer nut and the back cap seal body permits the back cap seal body to flex and expand with a plug valve body of the plug valve. This ensures that the back cap seals are not stressed and a longer service life results.

    摘要: An upstream seat ring and an auxiliary seat ring, which improve valve's capability resistant to erosion by the fluid carrying solid particles or containing liquid drops. One end of the auxiliary seat ring passes through bore of the upstream seat ring and the other end is fixed in the pocket of the valve upstream passageway. There are many bar barriers or analogous mechanism with rectangular, tooth-like or any other geometrical shapes cross-section around the circumferential surface of their bores, which are radially concaved inward or projected outward from the circumferential surface, are longitudinally extended an overall distance from one radial end face of the seats to opposite radial end face or a distance from the radial end face next to the upstream surface of the valve closure member towards the opposite radial end face, and spaced each other radially.

    摘要: A ball design for withstanding high differential pressures without leakage features a circumferential groove near the circle of contact on the ball with a surrounding seat. High differential forces are transmitted beyond the circle of contact so that deflection due to applied differential pressures results in flexing in the groove area while maintaining full circumferential seat contact to prevent leakage.
