  • Patent number: 9500290
    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.

  • Patent number: 9079053
    Abstract: The present invention realizes a new actuated valve type water flow detection device that can be applied to a pipe with a relatively large bore diameter. The water flow detection device A includes a coil spring for urging a detection rod in an opening direction of a valve body. Therefore, while detecting water flow by linking a rotation of the detection rod 11 to a rotation of the valve body when the valve body opens or closes by a differential pressure, the detection rod does not apply a closing load to the valve body that is released. Therefore, even when the rotation of the valve body is small because the water flow in the secondary side is small in a conventional actuated valve type water flow detection device, it is possible to increase an opening angle of the valve body.

    Abstract: A valve is provided with multiple ports joining multiple fluid conduits leading between fluid sources and fluid destinations. A central hub manifold or other control element resides within a body supporting the ports, and can rotate relative to the valve body. Fluid flow paths within the central hub or other control element are selectively aligned or not aligned with the ports. The valve indicates which ports are open or closed by providing unique marks adjacent the ports corresponding with being open or closed. When the positive marks are visible, such as through windows in a rotating structure fixed to the central hub or other control element, the corresponding ports are open. When the negative marks are visible, such as through other windows in the rotating structure, the corresponding ports are closed.

The valve body also includes a cam mounted within the valve body. A limit switch is directly connected to the cam such that the limit switch moves directly in response to movement of the diaphragm. Additionally, a reset pin extends from the valve body and interacts with the cam such that the cam may be reset from a closed position to an open position by moving the reset pin.

  • Patent number: 8763637
    Abstract: A rotary valve position indicator utilizes a magnet keyed to a shaft, and a magnetic field sensor mounted beside the magnet, to indicate the angular position of the shaft. A magnetic pole sensor detects the initial polarity of the magnet during setup to determine how to correlate the output readings of the magnetic field sensor with the position of the valve. The sensors are located so they permit the shaft to extend through to a mechanical visual indicator.

  • Patent number: 8763983
    Abstract: Embodiments of a method of operating a safety valve and a safety valve system are provided. The valve system includes a valve, an actuator, a mechanical override, and an indicator. The actuator includes a fail-safe mechanism and the indicator is configured to indicate whether the fail-safe mechanism is operable during use of at least one of the actuator and the mechanical override. In one embodiment, a method of operating the safety valve includes actuating the valve into an open position and sending a signal to indicate that the fail-safe mechanism is operable to move the valve to the closed position, while the valve is in the open position.

  • Patent number: 8757201
    Abstract: A device for airflow regulation in an air damper is disclosed. The device includes a twist sleeve of flexible material, the cross section of which substantially conforms to an outer tube in which the flow takes place, one end of the twist sleeve being disposed on the inner side of the outer tube and the other end of the twist sleeve being disposed in a tube sleeve which can be rotated under an axial displacement controlled in relation to the rotation. The outer diameter of the tube sleeve is smaller than the inner diameter of the outer tube, so that the tube sleeve slides easily in the outer tube. The tube sleeve is provided with a helical slot. The rotation of the tube sleeve is achieved by a gearwheel adapted to cooperate with the helical slot to pull around the tube sleeve.

    Abstract: An apparatus for actuating a valve includes a housing having an axis, a valve end, a cap end, and a cylindrical sidewall defining an inner diameter surface of the housing. A cap is connected to the cap end of the housing. An inlet is located in one of the cap and the housing. A plate is positioned within the housing, the plate having an outer diameter that slidingly engages the inner diameter surface of the housing. The plate moves between an extended position and a retracted position in response to pressure media from the inlet. A down stop is in contact with the plate. A seal nut has a first end in engagement with the down stop. The seal nut has a second end with an end surface, the end surface being spaced apart from the cap when the plate is in the extended position.

    Abstract: A status assembly to provide visual and electronic indication of the position (open, closed, in-between) of the ram of a ram-type blowout preventer (BOP). The assembly is capable of coupling with a hydraulic motor that can be used to open and close the ram locks. The status assembly includes a rotatable element protruding from the BOP, a gear rotatable by the rotatable element, and an indicator that indicates the rotation position of the rotatable element and thus the linear position of the BOP ram. Some embodiments can also include a sensor that outputs an electronic signal to the system operator and can be incorporated into the main display for the BOP control system. This device is able to give immediate feedback to operators and to indicate whether each ram has achieved its intended travel.
