Tool For Applying Or Removing Valve Or Valve Member Patents (Class 137/315.41)
  • Patent number: 9671041
    Abstract: Embodiments of a valve device that reduces noise and vibration that may occur during low flow conditions in fluid couplings (e.g., valves and flow regulators). These embodiments utilize a plug and seat arrangement with geometry to prevent pressure differentials that cause the plug element to open and close in a cyclic pattern. In one embodiment, the valve device includes a seat element with an aperture and a plug element with a boss that extends into the aperture when the plug element contacts the seat element. The boss has an outer surface that forms a gap, which defines an annular area proximate the point of contact between the seat element and the plug element that is sized to reduce Venturi flow effects that cause the cyclic pattern to occur.

  • Patent number: 9404613
    Abstract: An isolation tool for isolating small bore pipe has a spigot having a proximal section with diameter and a distal section with smaller diameter. A seal is provided on the tool around the smaller diameter section. In some embodiments, the isolation tool is located through a hole in the wall of the pipe and through a second hole in the opposite wall of the pipe, the tool arranged so that when the tool is located through the second hole the seal fills the bore of the pipe and isolates a section of the pipe. In other embodiments, the tool may be located between severed pipe sections.

  • Patent number: 6973939
    Abstract: An exit opening (78) in a cartridge (22) is alignable with an opening (48) in a housing (32) for communication to an external drain. The cartridge and the housing have positions of final secured and initial unsecured interconnections, when openings (78, 48) are respectively aligned and unaligned. A lever (52) is swivelably secured to the housing bottom wall (46), whose cap (54) can close housing exit tube (28); a projection (56) is engageable with the cartridge for effecting the closure when the housing and cartridge openings (48, 78) are not aligned. Three L-shaped keyways (60) in the housing interior mate with three keyways (82) in the cartridge, and have corrugated surfaces to provide a ratcheted secure connection between the cartridge and the housing when in the secure connection. A tool (92) is used to insert and to remove the cartridge into and from the housing.

  • Patent number: 6955183
    Abstract: Embodiments of a pressure tank valve socket are disclosed which may be used to safely remove the valve from a propane or other pressure tank without damaging the valve. The pressure tank valve socket applies force only to the sturdiest part of the valve and, thus, prevents injury to the more delicate parts of the valve.

  • Patent number: 6929024
    Abstract: An improvement for use with a hand operated wrench primarily intended for removing a cartridge from an opening, with such wrench having a slotted aperture at one end. This improvement comprises an elongate threaded device having a mounting shaft at one end, and tapered external threads at the other end, with an internally threaded hole extending partly along the length of the device. This mounting shaft is sized to be inserted into the apertured end of the wrench, with flattened shoulders on the shaft able to closely engage the slotted aperture of such wrench to prevent undesired rotation. The internally threaded hole is engagable by an elongate screw associated with the wrench, to prevent undesired separation during use. The external threads of the elongate device are of a diameter for tightly engaging and removing a fractured cartridge from an opening, such as in a valve body.

  • Patent number: 6901948
    Abstract: A removable flow restrictor 750 and a corresponding method for regulating flow through a fluid fertilizer distributor 700 are provided. A supply inlet port 712 is in fluid communication with a plurality of fluid outlet ports 716. The flow restrictor 750 is removable positionable within the fluid distributor 700 between the inlet port 712 and the outlet ports 716, for restricting flow between the inlet port 712 and the outlet ports 716. A restrictor engagement member 752, which may be a thread, on the flow restrictor 750, engages with a tool engagement member 762 on a retrieval tool 760. With the restrictor engagement member 752 engaged with the tool engagement member 762, the retrieval tool can be used to both position the flow restrictor 750 within the fluid distributor 700, and to remove the flow restrictor 750 from the fluid distributor 700. After positioning within or removing from the fluid distributor 700, the flow restrictor 750 may be disengaged from the retrieval tool 760.

  • Patent number: 6899120
    Abstract: A yard hydrant has an elongated wet pipe with a plunger that seals against the inside of a well casing. Lifting a pivoting handle at the top of the wet pipe lowers the wet pipe which opens a normally closed supply valve. Pressurized water can then flow up the wet pipe and out of a nozzle head mounted to the upper end of the wet pipe. Lowering the handle pulls the wet pipe upward, thereby clearing it from the supply valve which is spring biased to shut off the water supply. The handle has a cam that positively actuates a normally closed anti-siphon valve so that water left in the wet pipe can fall under gravity to a collection chamber within the well casing beneath the piston. Lifting the handle again lowers the wet pipe and forces the water in the collection chamber back up the wet pipe. At the same time, the anti-siphon valve will close and the wet pipe re-opens the supply valve.

  • Patent number: 6840280
    Abstract: These and other objects of the present invention are achieved by provision of a flow through ultrasonic system for facilitating the flow of flow-resistant materials. The system includes a supply of material and an ultrasonic horn having at least one passage extending therethrough. An isolating tube which is compatible with the material is provided passing through the at least one passage in the ultrasonic horn, the isolating tube in communication the supply of material and completely isolating the ultrasonic horn from the material. A converter imparts ultrasonic energy to the ultrasonic horn, and in turn to the isolating tube so as to inhibit the material from attaching to and clogging the isolating tube.

  • Patent number: 6840282
    Abstract: A method to set a hollow device into an undersea flow pipe uses a flexible pig driven by a flow flowing into said flow pipe to displace a hollow device to a point where a stop means halts a displacement of said hollow device, thereby setting said hollow device into position. A method to retrieve a hollow device into an undersea flow pipe uses a flexible pig driven by a flow flowing into said flow pipe to retrieve said hollow device from a location where said hollow device operates halted by a stopping means.

  • Patent number: 6810903
    Abstract: The invention is an improved conduit flow controller for selectively controlling the flow of fluid through an elongated conduit. The conduit has an aperture defined by a continuous peripheral edge in the sidewall of the conduit. An elongated housing surrounds the aperture and is sealingly connected to the conduit. A conduit stopper is movably mounted in the housing and is positionable in the conduit. The conduit stopper includes a deformable sealing element having opposed flat sides and an edge engageable with the conduit. A carrier is sealingly connected with the sealing element. A resilient seal is mounted on a carrier and is engageable with the continuous edge. The sealing element is cooperative with the seal to close a portion of the conduit to regulate the flow of fluid along the elongated conduit.
