  • Patent number: 9404561
    Abstract: A rotary-to-linear motion actuator having helical bevel gear and methods of use thereof are described. The actuator may be utilized with an apparatus for managing a fluid flow passage between one or more input ports and output ports. A pinion gear engages, and during operation turns, a bevel ring gear arranged on a helical path along an external periphery of a sleeve retaining a seat, which forms a fixed orifice. The teeth of the bevel gear are arranged on the helical path at the same pitch as external threads on the sleeve, which in turn, engage internal threads in a thrust tube. The trust tube is engaged with a thrust tube jam nut that locks the thrust tube into position within the valve body. The area of the flow passage is changed by movement of the fixed seat orifice axially with respect to a contoured plug assembly. The threads of the sleeve and the thrust tube resist axial load imparted by the pressure drop across at the fixed orifice.

    Abstract: A non-rising stem gate valve is provided that includes a drive sleeve disposed between the gate and the stem. The drive sleeve is coupled to the stem and isolates the moveable connection between the sleeve and the stem from fluid in the valve. The drive sleeve is also coupled to the gate such that movement of the drive sleeve along the stem moves the gate between the open and closed positions of the valve. Systems and methods incorporating the non-rising stem gate valve are also disclosed.

  • Patent number: 8919733
    Abstract: A device in a valve (1) includes a valve housing (2) with at least a first (3) and a second (4) fluid port. A closure element (5) including a sealing portion (15) and diaphragm (30) is arranged in the valve housing (2). The sealing portion (15) is movable between an open position and a closed position. The closure element (5) and valve housing (2) form a flow passage (11) which communicates with the fluid ports when the sealing portion (15) leaves the closed position. A second sealing portion (14) is arranged in contact with a support portion (25) of the valve housing (2). An abutment element (16) is arranged in contact with the second sealing portion (14). The abutment element (16) transmits a force via the second sealing portion (14) toward the support portion (25) to provide a seal. The force is at least partly exerted by a spring element.

  • Patent number: 8910921
    Abstract: A valve and stem sealing assembly capable of preventing leakage under demanding environmental and operating conditions. The valve comprises a body and bonnet secured together to house a flow-element, stem, and stem sealing assembly. The body may contain a body joint encapsulated within its liner. The flow-element is positioned between a first port and second port on the valve. The body and bonnet may be configured to eliminate rotational forces from being translated to the bonnet. The stem sealing assembly comprises a primary seal, primary shaft insert, spacer, and force transmitting member. The stem sealing assembly may also comprise a secondary seal and secondary shaft insert. The stem seal assembly is substantially adjacent to the stem, and configured to fit within an annular space or cavity between the stem and the first body half, second body half, and bonnet. The valve may also include a leak detection port.

  • Patent number: 8905376
    Abstract: Tunable check valves reduce valve-generated vibration to increase the reliability of tunable fluid ends. Selected improved designs described herein reflect disparate applications of identical technical principles (relating to, e.g., the vibration spectrum of an impulse). Tunable check valve embodiments comprise a family including, but not limited to, tunable check valve assemblies, tunable valve seats, and tunable radial arrays. Each such tunable embodiment, in turn, contributes to blocking excitation of fluid end resonances, thus reducing the likelihood of fluid end failures associated with fatigue cracking and/or corrosion fatigue. By down-shifting the frequency domain of each valve-closing impulse shock, initial excitation of fluid end resonances is minimized.

    Abstract: A live-loading assembly for exerting a sealing force on a compressible packing structure of a fluid handling device, such as a valve or pump, includes a pair of gland bolts each movably extending through opposite end lids of a tubular cartridge and through a Belleville spring stack disposed within the cartridge and bearing on a tubular piston rod having an end portion extending outwardly through one of the lids and having a spring force indicating scale disposed thereon. When packing force adjustment nuts are tightened onto the bolts, to increase the compression force exerted on the packing structures, one of the lids on each cartridge moves along the associated exposed piston rod scale to thereby provide a visual indication of the amount of spring force being created by each tightened nut.

    Abstract: In an angle valve, an externally threaded sleeve within the yoke surrounds the stem at an upper end of the stem. A yoke bushing fixed to the valve has internal threads matching with the external threading of the sleeve. A split collar assembly is located on the stem above the sleeve. The stem has a greater diameter itself, and/or via a nut, at a lower portion of the stem (below the sleeve) relative to the upper portion of stem. The plug stem is designed to pass through the yoke bushing making it possible to perform the normal open-close operation and grinding operation independently.
