摘要： A ball valve is disclosed having an improved seat ring particularly adapted for sealing a ball member in an end-loaded or top-loaded valve body. The ball is mounted for selective rotation and limited axial movement in a valve body passageway. The seat rings are disposed on diametrically opposite sides of the ball about valve inlet and outlet openings. Frusto-conical disc springs interposed between each seat ring and an associated valve body shoulder urge the seat rings into engagement with the ball. A rigid reinforcing ring is disposed intermediate of the flexible seat ring for integral movement with the seat ring and for reinforcing the seat ring against collapse under pressure. The reinforcing ring is received in an annular channel about the periphery of the seat ring and preferably comprises a split metal ring in a stressed and expanded condition.

摘要： A ball valve for low and high pressure applications including a metallic seat member that toroidally deflects into sealing engagement with a ball member outer surface upon valve assembly. The seat member includes an outer circumferential rim portion and a radially inward extending frusto-conical portion. The rim portion is radially interposed between an annular, resilient flange member and an annular support member. The rim portion and resilient flange member define a behind-the-seat seal while the frusto-conical portion and support member abuttingly engage during extreme pressure conditions for added structural support. The radially innermost edge of the frusto-conical portion has an arcuate conformation to inhibit scoring of the ball member surface.
摘要翻译： 一种用于低压和高压应用的球阀，包括在阀组件上环形偏转成与球构件外表面密封接合的金属座构件。 座椅构件包括外圆周边缘部分和径向向内延伸的截头圆锥形部分。 轮缘部分径向介于环形弹性法兰件和环形支承件之间。 边缘部分和弹性凸缘构件限定了座椅后密封件，而截头圆锥形部分和支撑构件在用于增加的结构支撑件的极压条件下邻接地接合。 截头圆锥形部分的径向最内边缘具有弧形构造，以阻止球形件表面的刻痕。

摘要： A tube fitting for joining resinous plastic tubing comprises a fitting body having an opening with a conically shaped camming mouth. A tube extends into the opening. A first ferrule is slidably received on the tube and has an exterior surface which faces the camming mouth. A second ferrule is also slidably received on the tube at a location outwardly of the opening and the first ferrule. The second ferrule has a nose portion which engages the first ferrule adjacent the tube and is snap fitted within a recess formed circumferentially of the tube prior to association of the tube with the fitting. The nose portion of the second ferrule is engaged in the recess in axial driving engagement with the tube prior to make-up of said fitting. A nut member is threadedly engaged with the body for driving the first and second ferrules into the camming mouth during fitting make-up.

摘要： A ball valve having a two component body with a bonnet section formed integrally with one of the body components. A first body member defines a first flow passage and a first end of a valve chamber. The second body member forms a second flow passage and a second end of the valve chamber. Formed about the first flow passage is a first sleeve member which extends axially into the valve chamber. A cylindrical stem receiving chamber is also formed in the first body member and extends radially outwardly from the valve chamber to open to the exterior of the first body member through an inwardly facing shoulder. Inner and outer radially spaced sleeves are formed integrally with the second body member and extend into the valve chamber circumferentially about the second flow passage. The inner sleeve is aligned with the first sleeve member formed about the first flow passage on the first body member. A valve ball is mounted in the chamber in axial alignment with the first and second flow passages. Seat rings are positioned about the first and second sleeve members and biased into engagement with the valve ball. An operating stem is provided for rotating the ball. The operating stem is positioned axially of the stem receiving chamber and has a pair of spaced, outwardly extending integral flanges located axially inwardly of the shoulder. Stem seal means are located between the pair of flanges and a resilient bearing ring is located between said shoulder and the outermost flange of said pair of flanges.
