    摘要: A valve (10) of an embodiment of the present invention has a tapered section (55) on an opening side of a depression (51a) of a body (1). When a projection (4b) of a ball (4) is inserted into the depression (51a), a part of a tip end edge of the projection (4b) is brought into contact with the tapered section (55), and the tapered section (55) guides the projection (4b) so that the entire circumference of the tip end edge of the projection (4b) is located on a bottom side with respect to the tapered section (55).

    摘要: A control valve assembly includes a valve body defining an inlet, an outlet and a fluid flow pathway therebetween. A ball valve is positioned within the fluid flow pathway and includes a rotatable ball having an inlet opening, an outlet opening and a flow pathway therebetween, an upstream seat ring positioned at an inlet side of the ball, and a downstream seat ring positioned at a downstream side of the ball, the seat rings being configured to substantially seal off fluid flow between upstream and downstream sides of the ball except through the ball fluid flow pathway. At least one of the upstream and downstream seat rings is a dynamic sealing seat ring. A retainer ring is positioned between the dynamic sealing seat ring and a portion of the rotatable ball to substantially prevent deformation of a portion of the dynamic sealing seat ring in a direction toward the ball.

    摘要: Valves having seats and counterseats that can be moved by fluid within the valve. In one embodiment, a valve includes a flow control assembly inside a body. The flow control assembly includes a ball rotatable between an open position and a closed position to control flow, a seat installed on the ball, and a counterseat installed in the body. The seat and the counterseat can move radially with respect to the ball and have mating surfaces that engage and seal against one another when the ball is in the closed position. The flow control assembly allows pressurized fluid in the body to cause net forces on the seat and the counterseat that push the seat and the counterseat toward each other when the ball is in the closed position. Additional valve systems, devices, and methods are also disclosed.

    摘要: A compact manifold ball valve having a valve body, valve ball, valve stem and two piece retainer system; the valve body including a valve chamber having first and second ends, and a first flow passage intersecting the valve chamber and valve ball. The valve ball can be trunnion supported and include pair of movable seat assemblies that can be used to seal the valve ball to the valve body. A two piece retainer can be used to hold in place the valve components, the two piece retainer including a first section which moves only linearly along with a second retainer piece that is a threaded ring that rotationally locks in place the first section of the two piece retainer. The two pieces of the retainer can be symmetrically located about the centerline of the flow passage of the valve body.

    摘要: A dual sealing ball valve comprises a valve body, conduit line connectors coupled to both sides of the valve body, a hollow ball disposed in the valve body, a sheet holder mounted on an inner circumferential surface of at least one of the conduit line connectors, a main sheet tightly contacting the ball around an inlet of the hollow ball, and an elastic sheet mounted on the front surface of the sheet holder. The sheet holder includes a sheet ring supporting the main sheet and the elastic sheet in a front direction, supporting the elastic sheet towards the main sheet, and pushed in the front direction by a pressurizing retainer and a sheet cap coupled to the sheet ring and contacting the main sheet to pressurize the main sheet in a rear direction and towards the elastic sheet.

    摘要: A ball valve is provided. The ball valve includes at least one load varying mechanism provided in the static body assembly. The load varying mechanism includes a biasing member pressing one of the ball seat seals against the outer surface of the ball of the ball valve with a variable sealing load force applied on the ball, toward the ball and coaxial with the direction of the fluid. The load varying mechanism also includes a movable member operatively connected to a cam and to the biasing member, a rotation of the cam translating the movable member coaxially to the direction of the fluid, in order to variably load the biasing member toward or away from the ball, based on the different positions of the ball.
