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 mounting bracket for securing a manifold valve to a support pipe is provided wherein plural support members extend outwardly from one leg of the bracket. The support members are designed to accommodate various manifold conformations, selective use of a steam block, and use of the same size mounting bolts. The mounting bracket is adaptable to securing on both horizontal and vertical support pipes through the use of a pair of U-bolts cooperating with four symmetrically spaced apertures. The mounting bracket facilitates installation of a differential pressure cell to an associated valve manifold independently from initial assembly of the manifold to the mounting bracket and connection of fluid system piping to the manifold.

摘要： A ball valve designed for high pressure shut-off at fluid pressures approaching the ultimate compressive stress of plastic annular seat rings which are employed. The ball member is trunnion mounted in order to carry the total force of the shut-off pressure and the seat rings are disposed in seat ring carriers. Each seat ring includes a spherical ball engaging surface having a radius slightly smaller than the radius of the ball. Each carrier is continuously urged toward the ball by a plurality of disc springs in order that the seat ring engaging surfaces will be in continuous sealing engagement with the ball surface. The seat ring engaging surfaces are configured so that at least the areas thereof located adjacent the outer diameters will be first to sealingly engage the ball. The valve components are configured and dimensioned to limit the effective area on which fluid pressure may act in urging the seat rings into ball contact for thus controlling compressive stresses which may be exerted on the plastic seat ring material. Also, fluid pressure urges the seat rings toward the ball to enhance sealing engagement with the ball regardless of the position of each seat ring upstream or downstream of the ball from the source of fluid pressure and also with the valve in the open position. The inventive concept involved may advantageously be employed in a variety of valve bodies to accommodate a plurality of fluid shut-off applications.
摘要翻译： 一种球阀，用于在接近塑料环形座圈的极限压缩应力的流体压力下进行高压切断。 滚珠构件是耳轴安装的，以便承载关闭压力的总的力，并且座圈设置在座圈环架中。 每个座圈包括具有稍小于球的半径的半径的球形球接合表面。 每个托架通过多个碟形弹簧被连续地推向球，以使座环接合表面将与球表面保持连续的密封接合。 座环接合表面被构造成使得至少其邻近外径定位的区域将首先密封地接合球。 阀部件的构造和尺寸被限制为限制流体压力可以起作用的有效面积，以将座圈推动成球接触，从而控制可施加在塑料座圈材料上的压缩应力。 此外，流体压力促使座圈朝向球以增强与球的密封接合，而不管球的上游或下游的每个座环的位置与流体压力源的位置以及阀处于打开位置。 所涉及的发明概念可以有利地用于各种阀体以适应多个流体切断应用。

摘要： A conduit fitting of the type having first and second threaded fitting components and at least one conduit gripping device, further includes a stroke limiting member that allows the fitting to be pulled up by applying a predetermined torque. In one embodiment, the stroke limiting member may realized as an integral or integrated load bearing member that functions as a torque collar and deflects under load. The disclosure also presents a gauging structure and method for fittings that can be pulled up by turns, by torque or both.

摘要： Two conduit gripping devices that are to be used together in a conduit fitting assembly are interconnected or held together as a cartridge or subassembly prior to assembly with fitting components to form a fitting assembly. In a more specific embodiment, one or both of the conduit gripping devices comprises a retaining structure by which the devices are mechanically connected together as a subassembly. For example, in one embodiment a front ferrule and a back ferrule for a tube fitting may be snapped together.

摘要： A fitting assembly is provided with a first fitting component having a stepped wall surface; and a second fitting component radially spaced from the first fitting component when the fitting assembly is in a finger tight condition prior to pull-up. When the second fitting component is displaced into contact with the stepped wall surface during fitting pull-up, the stepped wall surface assists in separating the first fitting component from the second fitting component upon fitting disassembly.

摘要： A fitting for a conduit is provided with first and second fitting components, a gripping member, and a live-loading mechanism. The first fitting component is adapted to receive a conduit along a central axis. The gripping member includes a gripping portion adapted to engage the conduit when the gripping member is tightened to the conduit. The second fitting component is adapted to be joined to the first fitting component to provide a seal between the gripping member and at least one of the first and second fitting components. The live-loading mechanism is adapted to hold the gripping portion in live-loaded engagement with the conduit when the first fitting component is separated from the second fitting component.
