  • Patent number: 11378083
    Abstract: A technique facilitates controlling barrier fluid via a mechanical pressure regulation system which may be coupled with a rotating machine at a subsea location. The mechanical pressure regulation system enables controlled supply of the barrier fluid to the rotating machine and comprises a mechanical valve mechanism. The mechanical valve mechanism automatically maintains a pressure differential between the barrier fluid and a process fluid within a desired range. According to an embodiment, the mechanical valve mechanism is mechanically actuated via pressures applied to a pilot piston so as to provide barrier fluid to the rotating machine when the pressure differential reaches a lower limit and to dump barrier fluid when the pressure differential reaches an upper limit.

  • Patent number: 10927965
    Abstract: A pilot valve system is controlled by the pressure differential between a lower chamber and an upper chamber. A fluid passageway in the lower chamber fluidly connects an inlet to first and second outlets. By varying the pressure differential, the placement of a stem within the fluid passageway is varied so fluid can flow between the inlet and only one of the first and second outlets at a time. Pressure in the lower chamber can be varied by using a second fluid to exert pressure against a bottom end of the stem. Pressure in the upper chamber is varied by using an adjusting screw to urge a spring against the diaphragm.

  • Patent number: 10562436
    Abstract: Various embodiments of the present disclosure provide a portable dunnage bag inflator that provides a compact, pressurized source of air and that is easily mounted onto a movable cargo mover (such as a forklift truck or a pallet jack). Generally, the portable dunnage bag inflator includes an impellor-driven blower that, in operation, draws air at atmospheric pressure through an air intake grid or air inlet into the impellor and expels the air through an inflation hose. Since the portable dunnage bag inflator includes an impellor-driven blower, the pressure of the expelled air is higher than atmospheric pressure. This enables dunnage bags to be inflated to the desired specifications at point-of-use (e.g., during or after loading of cargo into a cargo container) and eliminates the need for a compressed air supply.

  • Patent number: 9828832
    Abstract: A tool string carrying an external tool, such as a liner hanger, on a release mechanism is lowered into the wellbore. Interlocking lugs and J-slot profile, defined between the exterior surface of the mandrel and interior surface of the release mechanism, allow relative movement of release mechanism and mandrel without releasing the release mechanism. The relative movement allows mechanical operation of a valve or other tool positioned below the release mechanism. Weight-down and rotation of the tool string and mandrel actuates the lower valve assembly by turning a sleeve into alignment with cooperating members of the mandrel. The sleeve, no longer constrained, moves longitudinally in response to a biasing mechanism. Movement of the sleeve allows closure of the valve. After actuation of the valve tool, further weight-down releases the release mechanism from the carried tool.

  • Patent number: 9580287
    Abstract: An apparatus for preventing the formation of beer stones and a gas-induced phenomenon, in which foamy beer spurts out of a draught beer container, is disposed in a pipe between the draught beer container and a draught beer dispensing apparatus so as to prevent the gas-induced phenomenon from occurring when the beer is discharged from the draught beer container to the draught beer dispensing apparatus, and to remove and prevent the formation of beer stones deposited on the inner surface of the pipe, between the draught beer container and the draught beer dispensing apparatus, or on the inner surface of the draught beer dispensing apparatus.

  • Patent number: 9297560
    Abstract: A dehumidifier for a compressor, including: a plurality of dehumidifying members that absorb moisture; and a flow passage controlling valve module that enables a low-temperature vapor refrigerant to alternately flow into the plurality of dehumidifying members and enables the low-temperature refrigerant to flow into a compressor in a state where moisture contained in the low-temperature refrigerant is absorbed and is removed, enables a high-temperature vapor refrigerant ejected from the compressor to alternately flow into the dehumidifying members and regenerates the dehumidifying members. Thus, since a liquid-state absorbent contained in a refrigerant flowing into the compressor is removed by the dehumidifier, damage caused by liquid compression and corrosion of the compressor can be reduced. In addition, the structure of the dehumidifier is simple, and an additional external heating source is not required.

  • Patent number: 9016302
    Abstract: A cold/hot water balance valve prevents burning or scalding of the users. The valve is accommodated in the holding space preset into a dual-temperature ceramic valve. The balance valve mainly includes a hot water stop flange, protruded from a first lateral end wall, and meshed with a first end of a moveable spool to block a hot water stream when the first end shifts towards the first lateral end wall. A minimum cold water retaining portion is protruded from the second lateral end wall. When the second end of the moveable spool shifts towards the second lateral end wall, the minimum cold water retaining portion will be abutted onto the second end of the moveable spool, such that a minimum flow gap is reserved between the second end and the second lateral end wall, allowing for constant flow of water stream through the cold water slot of the moveable spool.

  • Patent number: 9004094
    Abstract: The present invention concerns a valve (1), a valve closing body (14) and use of a valve (1) and a valve closing body (14) of the type used for injecting dry powder which is mixed with liquid, and where the dry powder is supplied under the liquid surface in a mixing vessel (11) in which a vacuum is typically maintained. The novel feature of a powder valve (1) according to the invention is that a closing body (14) of the valve in the closed position extends through the valve seat (13) of the valve and into the wet environment. It is hereby achieved that when the valve (1) is opened, powder or dust from powder is not deposited on the valve closing body (14). This is in spite of the valve closing body (14) being wet, due to contact with the liquid to which the powder is added. Due to its elongated shape, the valve closing body (14), which in the withdrawn position opens for inflow of powder, has the property that the inflowing powder dries the valve closing body (14) at first and keeps it dry subsequently.

  • Publication number: 20150096619
    Abstract: An apparatus has a pilot-operated spool valve connecting first and second work passages selectively to a supply conduit and a tank conduit. A first check valve normally allows fluid flow only in one direction from the first work passage to a first workport and when pilot-operated allows bidirectional fluid flow. A second check valve normally allows fluid flow only from the second work passage to a second workport and when pilot-operated allows bidirectional fluid flow. A first pilot valve selectively applies pressure to one end of the spool and to pilot operate the first check valve. A second pilot valve selectively applies pressure to another end of the spool and to pilot operate the second check valve. When fluid drains from a workport to the tank conduit, the associated check valve operates to maintain a predefined pressure in the first or second work passage through which that fluid flows.

  • Publication number: 20150083257
    Abstract: A valve element has a packing material, whose one side surface touches and leaves a valve seat as a sealing surface, and a support member, which is driven in opening and closing directions of a valve section by actuating an actuator. The support member includes a supporting surface, which is in contact with a side surface of the packing material opposite to the sealing surface of the packing material, and an engagement part, which supports a peripheral edge part of the packing material in a manner such that the engagement part is engaged with the peripheral edge part. A ring-shaped fluid flow passage is formed between the supporting surface of the support member and the packing material, and this fluid flow passage communicates with an upstream passage.
