    Abstract: A method to detect cycling of components that result from use of a tight shut-off mode on a valve assembly. Embodiments of the method use operating data from the valve assembly. This operating data includes data that reflects a position for the closure member relative to the seat. This position often corresponds with a measured position of one or more components (e.g., the valve stem) on the valve assembly. In one embodiment, the method includes steps for comparing the measured position to a boundary criteria that defines one or more boundary values proximate, and often equal to, the threshold levels of the tight shut-off mode. The method can also includes steps for identifying patterns in the data that indicate that the closure member is cycling from its closed position to a second position due to tight shut-off mode.

  • Publication number: 20150021503
    Abstract: The invention relates to an on-off valve with a pressure reducer intended to be connected to a gas cylinder. The objective of the invention is to ensure that the device is closed and put into service by way of simple and reliable means at high pressures. A shutter is controlled by a mobile part of the valve with pressure reducer, forming a low-pressure chamber of the device. The shutter is subjected to an elastic force in the closing direction. A working spring of the valve with pressure reducer acts on the mobile part in the opening direction. A rotary control member working over at least one turn makes it possible to compress the working spring into the position in which the valve with pressure reducer is put into service. In the closed position, a plate of pusher of the control member is remote from the working spring.

    Abstract: A manual valve operator with override clutch apparatus is disclosed for selectively actuating a valve. The apparatus includes an operator housing defining an enclosure. An input shaft is rotatably supported by the housing and a worm wheel has a first and a second side, the second side of the worm wheel defining a clutch drive. The worm wheel is disposed within the housing and intermeshes with the input shaft such that when the input shaft is driven, the input shaft drives the worm wheel and the clutch drive about a rotational axis. A sleeve has an outer surface which defines an annular groove. The sleeve has a driven end and an output end. The driven end of the sleeve cooperates with the clutch drive of the worm wheel for selective engagement of the clutch drive and the driven end of the sleeve. A clutch actuating handle is rotatably supported by the housing. The clutch actuating handle has a first and a second end.

  • Publication number: 20140307527
    Abstract: A method and assembly to produce data pulses in a drilling fluid in a drill string. The assembly comprises a shear valve that includes a valve member mounted in a valve passage in fluid flow communication with a fluid flow conduit of a drill string to which the assembly is connectable. The valve member is connected to a reciprocation mechanism comprising a rocker, a driven crank arrangement, and a slider member that provides a sliding coupling between the crank arrangement and the rocker. The slider member is pivotally connected to the crank arrangement, is keyed to the rocker for angular displacement about a valve axis, and is radially slidable relative to the rocker, so actuation of the crank arrangement causes angular reciprocation of the rocker, and hence of the valve member, about the valve axis, to produce data pulses in the drilling fluid.

  • Patent number: 8783277
    Abstract: In an actuator, an electric power supply to a position-detecting detector for an object to be driven can be carried out in a timely manner during a power failure to thereby suppress an electric power consumption in the position-detecting detector, whereby duration time of a power-failure compensation battery can be prolonged, and a variety of detectors can be selected and utilized without limitation in accordance with a use environment and usefulness. During the power failure, a switching means 40 establishes a linking state in which an input shaft 11 of a reduction mechanism 10 and a manual inputting means 30 are linked to each other. When the linking state is detected by a detecting means, an electric power is fed from a battery 80 to a rotation detector by a control section 70, so that the control section 70 can obtain a displacement of the object to be driven, based on a signal output from the rotation detector.
