  • Patent number: 10914390
    Abstract: A fluid valve includes a valve body, and a valve plug disposed in the valve body. The valve body includes a base and a cylindrical sidewall that together define a valve plug chamber. The valve body includes valve ports. The valve plug is rotatable relative to the valve body about a rotational axis. The valve plug supports an annular seal in such a way that, a) for certain orientations of the valve plug with respect to the valve body, the seal abuts and inner surface of the sidewall and provides a fluid-tight seal between the valve plug and the valve body, and b) during rotation of the valve plug relative to the valve body, the seal is moved relative to the valve body along a circular path. At least one of the valve ports includes a guiding feature that guides the seal along the circular path.

An energizer ring (14) located within the groove (10c) can reciprocate axially with respect to the o-ring (12). The energizer ring (14) moves axially toward the o-ring (12) in response to fluid pressure against a surface (14a) of the energizer ring (14) opposite from the o-ring (12) to axially compresses the o-ring (12), causing the o-ring (12) to expand radially outwardly into sealing contact with the other valve member (10b).

  • Patent number: 8979068
    Abstract: A differential pressure sealing device for use with ball valves that utilizes the pressure of the fluid being communicated in a piping system to increase the sealing force created by the sealing device. Fluid being communicated through a ball valve is provided to a sealing device that includes some type of element for creating a bias force. The pressure of the fluid being communicated increases the sealing pressure created by the sealing device. In this manner, the bias force created in the sealing device benefits from the pressure of the fluid being communicated to enhance the sealing when used with a ball valve or similar component.

  • Patent number: 8720854
    Abstract: A seal assembly is provided for a rotary ball valve having a top-mounted bonnet, thereby allowing the seal assembly to be installed and removed without removing the valve from the pipeline. In an embodiment, the seal assembly may include a seal ring disposed within the valve interior and biased toward the ball element of the valve. A seal carrier may be disposed between the seal ring and the valve body, and the seal carrier may be removably secured to the valve body by a plurality of bolts disposed in the valve interior. A primary leak path may exists between the seal ring and the seal carrier and a secondary leak path may exists between the seal carrier and the valve body. A first and second auxiliary seal may prevent fluid flow through the primary and secondary leak path, respectively.

  • Patent number: 8695633
    Abstract: Aspects of the invention are associated with the discovery of methods for operating rotary valves that reduce or minimize wear of the seal sheet, which is often the limiting factor in overall processing capability of the valve. The control of certain parameters associated with the rotary valve operation, and particularly the seating pressure of the seal sheet (e.g., the dome pressure), can extend the useful life of the seal sheet, thereby avoiding excessive maintenance and downtime costs. In preferred embodiments, control is on a real time basis.

  • Publication number: 20130313457
    Abstract: A valve including a flow control assembly having an adaptive, floating closure member is provided. In one embodiment, a ball valve includes a floating closure member having a shoulder enclosed within a recess of the valve body. The recess is larger than the shoulder of the closure member and allows axial movement of the closure member with respect to the valve body and along a flow path through the valve. Additional valve systems, devices, and methods are also disclosed.

  • Patent number: 8560139
    Abstract: An automatic flow control apparatus includes a solar cell module that provides a received light signal, an energy storage module, a charging circuit, a regulating module, a control module, a rainfall detection module for generating a detected rainfall signal, and a pair of conductors. The control module converts the received light signal and the detected rainfall signal into measured light data and measured rainfall data, and stores a measured data set that includes the measured light data and the measured rainfall data. The controller determines based on at least the measured data set whether to output a control signal to the regulating module for controlling regulation of fluid flow.

  • Patent number: 8490945
    Abstract: A valve includes a valve body, a valve element to selectively control flow through the valve, and a seal member and seat member together providing a fluid-tight seal between a valve cavity and a fluid passage in the valve body. A live-loaded biasing member is adapted to apply a live-loaded sealing force to the seat member to bias the seat member toward sealing engagement with the valve element. When the pressure in the fluid passage exceeds the pressure in the valve cavity, an unbalanced passage pressure load biases the seat member toward sealing engagement with the valve element. When the pressure in the valve cavity exceeds the pressure in the fluid passage, an unbalanced cavity pressure load biases the seat member toward sealing engagement with the valve element. The live-loaded sealing force is in parallel with each of the unbalanced passage pressure load and the unbalanced cavity pressure load.

  • Patent number: 8434515
    Abstract: The present invention relates to a sleeve valve (1), which sleeve valve (1) can be used offshore or onshore to control the fluid flow between a hydrocarbon reservoir and a tubing in a well in the hydrocarbon reservoir. The sleeve valve (1) comprises an outer and an inner sleeve (2, 3) which are coaxially and rotatably arranged relative to one another, wherein in each of the sleeves (2, 3) there is provided at least one through opening (4, 18). The sleeves (2, 3) are rotated relative to one another with the aid of a suitable device, so that they can selectively be brought into an open, closed or other positions therebetween so as thereby to be able to control the fluid flow through the sleeve valve (1).

  • Patent number: 8360395
    Abstract: A sliding valve assembly includes a valve body having a fluid conducting port adjacent to a fluid impervious surface. The actuator allows fluid to travel through the valve assembly and into a fluid blocking position where the fluid impervious surface obstructs the fluid from traveling through the valve assembly. First and second sealing assemblies include a primary seal ring, a secondary seal ring around the primary seal ring, and a spring forcing the primary seal ring against a sealing surface. As pressure in the system increases, this pressure is delivered to the sealing assemblies to force them against the sealing surfaces to enhance the sealing relationship. Cams and cam followers affixed to the valve body overcome the frictional forces of the sealing system and the valve body and valve housing to increase the efficiency of the valve assembly and the system in which the valve assembly is used.

  • Patent number: 8286937
    Abstract: The presented valve (1) is based on two axially adjustable sleeve-shaped valve seat rings (14, 36) that are associated with locking arrangements in the form of annular armature plates (22, 35) and associate holding coils (24, 36). The valve closure member (39) can be variably adjusted via a position adjustment drive. Said valve closure member has a double function. On the one hand, it acts to move the valve seat rings (14, 26) into locking position and, on the other hand, it acts to control the gas flow.

  • Patent number: 8272401
    Abstract: A pressure balanced rotary valve can be made more compact if the ports on the stator within can be located on a port pitch circle of smaller diameter. In certain circumstances for rotary valves used in pressure swing adsorption devices, it is acceptable for the spacing between the ports to be made smaller than the ports themselves. In a rotary valve comprising variable loading means (e.g. pistons) and fixed loading means (e.g. springs), this can involve reducing the piston size and increasing the load provided by the springs.
