摘要： Disclosed embodiments include ball valves with an asymmetric seal and seat, to minimize seal wear. In embodiments, a seal is disposed upon a ball with a first and second section, where the first section of the seal is disposed at a different angle from the second section. A seat has a first and second section at different angles that correspond to angles of the first and second section of the seal, respectively, such that the seal fully contacts the seat when the ball is in a closed position. When the ball is rotated to an open position, the different angles of the first and second sections allow the second section of the seal to clear the first section of the seat without contact.

摘要： A flat bottom ball valve is provided in the present disclosure. According to an example, the flat bottom ball valve includes a valve body, a valve core, a valve rod, a bonnet and a flow path. The valve core is mounted inside the valve body. The valve rod is mounted on two opposite sides of the valve body, perpendicular to a liquid flow direction and capable of driving the valve core to turn over. The bonnet is movably mounted on the valve body and parallel to the valve rod. The flow path is defined inside the valve body and connects two ends of the valve body. The valve core includes a main body part, a connecting part formed by extending symmetrically from two sides of the main body part, an accessory defined on the main body part and a first mounting hole in the connecting part to engage with the valve rod. The valve core swings around the valve rod along a path above the valve rod and is capable of being hermetically engaged with the valve body to turn off/on the flow path. A horizontal center line of the main body part is parallel to a horizontal center line of the first mounting hole in the liquid flow direction of the flow path.

摘要： A rotary valve and a quick exhaust valve for a railway vehicle in which high sealability and operability at the time of valve opening and closing are ensured. Outflow/inflow ports (10, 11) and a discharge port (12) are formed in a valve body accommodating part having a spherical surface part or a tapered surface part formed on part of an inner periphery in a body (2), and a valve body (3) is rotatably inserted from an opening which is open from the valve body accommodating part. A spherically-shaped surface part or a tapered-shaped surface part is formed at a position opposing the spherical surface part or the tapered surface part, a plurality of through ports communicating the outflow/inflow ports or the discharge port and an attachment groove opposing the outflow/inflow ports in a direction crossing the through ports are formed, and a seal member is attached to the attachment groove.

摘要： Ball valves and ball valve components usable to control the flow of fluids and methods for manufacturing said ball valve components. Ball valves include a ball member comprising two curved segments of like shape and size, which are integrally joined and disposed symmetrically to one another relative to the axis of rotation of the ball member. A bore extends through the joined first and the second curved segments, wherein the first end of the bore is located on the first curved segment and the second end of the bore is located on the second curved segment. Each curved segment is disposed symmetrically to one another, relative to the axis of rotation. The area of separation, between the curved segments, defines shoulders of like configuration, wherein each shoulder is located symmetrically with respect to the other relative to the ball member's axis of rotation.

摘要： A method and apparatus for controlling fluid flow with a quarter-turn ball valve with seats operated to lift off the sealing surface of the ball valve prior to ball rotation and to reseat upon completion of the ball rotation. One embodiment shown relates to a quarter-turn ball valve having a rotatable cam with an eccentric camming disk that engages a cam pocket in the ball seats to reciprocally lift off the sealing surface of the ball valve prior to ball rotation and to reseat upon completion of the ball rotation. An embodiment is also shown that provides filler pieces that restrict that flow around the ball valve whenever the ball seats are lifted off the surface of the ball valve.

摘要： A ball valve (10) for sealing a conduit (12) is described. The ball valve includes a housing having a throughbore and a valve seat. An apertured ball element (18) is mounted within the housing and is rotatable about an axis of rotation (38) between a throughbore open and a throughbore closed position. The apertured ball element (18) has a first portion (20) and a second portion (22) coupled together which are rotatable and moveable relative to each other. The first portion has a sealing surface for engaging with the valve seat. In use, in the throughbore closed position, the second portion is moveable relative to the first portion to axially displace the first portion from the axis of rotation towards the valve seat such that the sealing surface on the first portion of the apertured ball forms a seal with valve seat.

摘要： A high temperature ball valve seal is disclosed that achieves Class IV shutoff for operating temperatures above 550 degrees F. The ball valve seal includes a C-seal positioned between a main seal and a seal housing to prevent fluid from flowing through a secondary flowpath when the ball valve is in a closed position.
