  • Patent number: 9470330
    Abstract: An actuating device or displacing a control device, such as a valve, gate valve or other control mechanism, in particular for use in oil or gas production systems, comprises a motor-gear unit (21) and a thread drive (22) which is operable by said motor-gear unit (21) and which comprises at least a threaded spindle (23) and a screw nut (24). The threaded spindle (23) is displaceable in an essentially axial direction so as to displace the control device (2) between a use position (7) and a non-use position (8, 9, 19, 20). To ensure a safe displacement into the non-use position in a simple way and independently of the pressure conditions prevailing between conveying medium and inner medium, the threaded spindle (23) is substantially axially displaceable beyond the use position (7) into a second non-use position (9). The invention also refers to a corresponding method for displacing the actuating device.

    Abstract: A system for positioning a seal member on a movable valve stem. The system includes an O-ring surrounding a lower portion of a movable valve stem. A snap-on retaining collar is pushed into place along the valve stem. A lower edge of the collar contacts the O-ring. The interaction between the snap-on collar and the O-ring prevents the O-ring from flexing outwardly and becoming dislodged from the valve stem. The snap-on retaining collar can be formed from various materials, such as but not limited to plastic.

    Abstract: A lock open device for use with a valve in a hydraulic fracturing system, which maintains the valve in an open position. The lock open device includes a plate with beveled edges and spring loaded ball bearings strategically disposed to contact the edges and interfere with axial movement of the plate. The plate couples to a gate member in the valve, so that the interference between the plate and the ball bearings maintains the valve in a designated open or closed position. The angle of the bevel regulates how much force is required to urge the plate past the ball bearings to thereby open/close the valve.

    Abstract: Systems, devices, apparatus, and methods of locking and unlocking a door that is slidable by articulating wheels in tracks, over an entry port to a storm water structure. Locking the door can be accomplished by rotating bolts that are attached to cams. Rotating the bolts causes the cams to press the door against the tracks. Sealing strips can be compressed between door edges and the track to prevent water from passing around the door. A vacuum truck can remove water and debris from the vault/structure. Other versions allow doors to move downward to allow water to overflow the door. The door can slide upward so water can flow underneath. A door in door version has a secondary door slide up and down in tracks in a main door.

  • Patent number: 8695637
    Abstract: Embodiments of a gate valve equalization system comprise: a gate valve; a gate; a preloading valve arrangement; a floating coupler assembly; a relief valve arrangement; and a means for control. The preloading valve arrangement permits fluid to enter the valve body from the upstream side of the gate. The means for control serves as a control interface allowing engagement of the floating coupler assembly and opening/closing of the gate valve. Engagement of the floating coupler, engages the assembly relief valve arrangement and allows redistribution of fluid pressure and circulation of fluid from one side of the gate to opposing side of the gate within the gate valve.

    Abstract: A slide blind controls flow through conduits at a flanged connection. The slide blind has a right and left working plates configured such that one of the working plates is sealed between the flanges a perimeter thereof adjacent to inner sides of the flange bolts. A joiner member connects the right and left working plates, and handle members extend in right and left directions from the corresponding working plates. The joiner and handle members have a thickness less than the thickness of the right and left working plates. The handle members and the joiner member define first and second sets of bolt holes to fasten the slide blind with either the right or left working plate between the flanges.

  • Publication number: 20140061524
    Abstract: A valve with at least two active positions is disclosed. When set in a first position, the valve can be connected to a first channel. While set in a second position, the valve can be connected to a second channel. The valve constitutes a part of a structure of a compressor, preferably a compressor in a tire repair kit. The tire repair kit also includes a cassette with a sealing mass. The valve serves as a rotary valve, which, once set in the first position, forms a channel through which compressed air flows to an outlet. Once set in the second position, the rotary valve forms the other channel through which compressed air flows to the cassette with a sealing mass. By using the rotary valve, the compressor is useful not only for connecting to a punctured tire requiring repair, but also for other purposes.

    Abstract: A high efficiency operator assembly is for a valve for controlling flow through a passage, the valve including a closure element movable between a closed position at which the member substantially obstructs the passage and an open position. The operator assembly includes a movable stem having opposing ends, a first end being connectable with the closure element such that displacement of the stem moves the closure element between the open and closed positions. A stem driver is rotatable about a central axis, engaged with the stem, and configured to displace the stem when the driver angularly displaces about the axis and an input device is rotatable about the axis. A lock mechanism or a clutch is engageable with the stem, the stem driver, or the input device to retain the closure element at a particular position when the input device remains at a particular angular position about the input axis.

  • Patent number: 8651767
    Abstract: Systems, devices, apparatus, and methods of locking and unlocking a door that is slidable by articulating wheels in tracks, over an entry port to a storm water structure. Locking the door can be accomplished by rotating bolts that are attached to cams. Rotating the bolts causes the cams to press the door against the tracks. Sealing strips can be compressed between door edges and the track to prevent water from passing around the door. A vacuum truck can remove water and debris from the vault/structure. Other versions allow doors to move downward to allow water to overflow the door. The door can slide upward so water can flow underneath. A door in door version has a secondary door slide up and down in tracks in a main door.

  • Publication number: 20140023460
    Abstract: Embodiments disclosed herein generally relate to a slit valve door assembly for sealing an opening in a chamber. A slit valve door that is pressed against the chamber to seal the slit valve opening moves with the chamber as the slit valve opening shrinks so that an o-ring pressed between the slit valve door and the chamber may move with the slit valve door and the chamber. Thus, less rubbing of the o-ring against the chamber may occur. With less rubbing, fewer particles may be generated and the o-ring lifetime may be extended. With a longer lifetime for the o-ring, substrate throughput may be increased.

    Abstract: A gate valve is disclosed that may be installed in a pressurized pipe or conduit. The gate valve includes a cylindrical gate housing that has a slot through which a rectangular gate slides between an open and closed position. The gate and gate housing provide seals between the gate valve and the housing section that houses the gate housing when the gate valve is in either an open or a closed position. The bottom seal that engages the pressurized pipe may be equipped with stiffening shields for a higher pressure rating. The operating torque to raise and lower the seal assembly has been substantially reduced by the design of the sliding gate within the gate housing.
