  • Patent number: 9518665
    Abstract: A ball valve including upstream and downstream seats and a ball having a flow opening disposed between the upstream and downstream seats. A flow path is defined through the valve only when the ball is disposed in an open position. In one embodiment, when the ball is disposed in a closed position the upstream seat may intermittently disengage from the ball to relieve hydrostatic expansion of a liquid within the ball resulting an increased pressure that is greater than a pressure within a body cavity of the valve outside the ball. In another embodiment, a distance between the upstream and downstream seats is greater than an outer diameter of the ball and the ball engages only one of the upstream and downstream seats when disposed in the closed position and a pressure differential is defined between the upstream and downstream seats. The upstream and downstream seats may each include a partially spherical sealing surface that may have a crenulate configuration.

The center post has a pentagonal recess therein which receives an insert, the insert having an inner recess which corresponds in shape to the operating nut. A domed housing is slid over the operating nut and can rotate with respect thereto. A circular groove in the center post receives a projection from a security plug which has been threaded through a threaded bore in the domed housing. The security plug has a socket therein which includes a recess which is off-set slightly from the axis of the plug and is only operable by a security tool having an off-set projection that is receivable in the recess. Without possession of the security tool, it is very difficult to achieve sufficient purchase on the plug to rotate the plug and withdraw the plug sufficiently away from the circular groove in the center post to remove the domed housing.

Each lobe has a flat portion that extends substantially radially away from the side wall and a curved portion that extends from the flat portion to the flat portion of an adjacent lobe. A special tool uses the leverage that is gained from the flat portions of the lobes to tighten the cap threads onto the threads of a stem portion. Since the leverage gained from the lobes, which is used to tighten the nut fastener, cannot be used to loosen the fastener, it is much more difficult to remove the nut fastener.

    Abstract: A breakaway unit which is adapted to be mounted in series flow relation with a fuel nozzle. The breakaway unit comprises a flex section which assures an axial transmission of forces to a valve section which is separated when a vehicle drives away from a dispensing unit with the nozzle lodged in its fuel tank. The valve section comprises inlet and outlet couplers and means for releasable locking the couplers in an assembled relation. These means comprise fingers which are flexed outwardly when a separating force exceeds a predetermined value. Garter springs embrace the fingers to accurately control at which the couplers will separate. The fingers engage angularly spaced lugs which permit the fingers to be telescoped therebetween and then rotated to a locking position to facilitate reassembly of the couplers with a minimum of effort. Alternate embodiments of the invention disclose other forms of spring means for accurately controlling the force at which the couplers will separate.

  • Patent number: 4962819
    Abstract: A mud saver valve for insertion within the drill string to retain mud in the drill pipe and prevent the mud column from flowing past the valve when pumping is interrupted. The valve body has a tubular body and a piston having an axial passage for the flow of drilling mud. This piston is biased within the body by a spring and axially movable in response to the mud flow. A check valve plug is disposed within the bore which may be removed to run wireline tools. The plug is seated within a reduced diameter portion of the body and includes a replaceable inner sleeve which engages the piston to prevent flow through the valve. The inner sleeve is replaced as it becomes worn due to the erosive forces of the drilling mud.

  • Patent number: 4955949
    Abstract: A mud saver valve for insertion within the drill string to retain mud in the drill pipe preventing the mud column from flowing past the valve when pumping is interrupted. The mud saver valve includes an internal check valve which permits increased flow of mud upward through the valve when a predetermined downhole pressure is reached. The increased flow of the check valve prevents a blow-out of the plug spear in the event sudden upward pressure is encountered. The check valve forms a part of the plug spear which is removable from the mud saver valve to facilitate the running of wireline tools.

  • Patent number: 4928726
    Abstract: A valve seat member (18) presenting a valve seat surface (20) at one end against which an associated valve (16) seals. A valve stem guide (36) is supported in a central flow passage (34) of the valve seat member (18) by two diametrically opposed arms (38). An annular abutment surface (44) extends radially into the flow passage (34) and is spaced axially below the valve seat surface (20) and above the arms (38) for providing a ledge with which a removal tool (42) engages to extract the valve seat member (18) from a slush pump deck (12). The associated valve (16) includes a valve body (72) having a shape defined by a segment of a sphere centered at the apex (70) of a cone (68) which simultaneously defines the shape of a peripheral sealing face (74) of the valve body (72) and the shape of the valve seat surface (20).

  • Patent number: 4890817
    Abstract: A quarter-turn valve comprises a housing formed with a cylindrical socket, and a cylindrical plug receivable within the socket and having a bore extending diametrically through the plug for establishing communication between the inlet and outlet nipples in the open position of the plug, but terminating the communication when the plug is turned to its closed position one-quarter turn from the open position. The plug is formed with a finger-piece projecting from the housing for manually rotating the plug to its open, closed or an intermediate position. The plug is closed at its bottom, such that the fluid flowing through the bore subjects the plug to a fluid pressure which is balanced on all sides of the plug, thereby facilitating turning of the plug and preventing its accidental ejection when subjected to a high pressure.

  • Patent number: 4861241
    Abstract: Apparatus by which a check valve assembly of a reciprocating pump can be removed. A valve stem of the valve assembly is received within a valve guide which is mounted in a valve guide bracket. The bracket is pivotally attached to a yoke. The yoke is removably fastened to an adaptor. The adaptor is seated in an access port arranged perpendicular respective to the passageway within which the valve seat is mounted. The compressive force of the valve spring maintains the bracket and yoke in assembled configuration respective to the adaptor. The bracket and yoke can be pivoted apart, against the spring force, and removed through the adaptor and then the adaptor can be removed from the access port, thereby gaining access to the remainder of the valve assembly.

  • Patent number: 4718444
    Abstract: Selective retraction of a spring-biased valve seat from slidable sealing engagement with a ball valve member is effected by a threaded retraction tool inserted through a threaded retraction port normally sealed by a removable sealing screw and gasket. The tapered distal end of the tool contacts a radially outward-facing and convex camming surface of the valve seat that tapers toward the forward/sealing end of the seat. Rotation of the tool in a direction to increase insertion causes the distal end of the tool to slide along the camming surface while forcing the valve seat away from the valve ball in opposition to the resilient bias sealing force. The taper in the camming surface may be provided as a smooth generally parabolodial configuration or as discrete surface segments subtending different respective cam angles with a reference plane oriented perpendicular to the direction of the spring bias force.
