Abstract: A fluid coupling includes a body, a poppet valve assembly, a handle shaft assembly, and a retention member. The body has a fluid conduit, a through-hole extending through a sidewall, and one or more openings that extend between an external surface of the body and an interior of the through hole. The poppet valve assembly is disposed within the fluid conduit and is selectively movable between an open position and a closed position. The handle shaft assembly extends through the through-hole and into the fluid conduit and is interconnected with the poppet valve assembly such that the handle shaft assembly can be actuated to move the poppet valve assembly between the open position and the closed position. The retention member is insertable through the one or more openings and into the through-hole to interact with the handle shaft assembly to selectively hold the handle shaft assembly in the body.

Abstract: A fluid system coupler includes a coupler body having an open end for receiving an adaptor therein. A seal assembly is movably disposed within the coupler body for selective sealing engagement with an adaptor. Lever cams pivot into or out of slots in the coupler body between locked and unlocked positions to fasten or unfasten the adaptor to the coupler. A handle is movably connected to the coupler body. Movement of the handle moves the seal assembly within the coupler body. Movement of the handle also results in movement of the lever cams between the locked and unlocked positions. A poppet assembly is mounted to the seal assembly. The poppet assembly can selectively open or close a fluid passageway through the coupler.

Abstract: A breakaway coupling includes a body and a valve assembly inside the body. The body includes a fluid conduit and a shear groove between first and second portions. The shear groove is designed to crack, break, or separate under certain conditions. The valve assembly is designed to shut off fluid flow through the fluid conduit when the shear groove cracks, breaks, or separates. The valve assembly includes a valve seat, a sealing element, one or more pins, and a biasing member. The one or more pins hold the sealing element in an open position while the shear groove is in tack, and allow the sealing element to move to a closed position (with the help of the biasing member) in the event the shear groove cracks, breaks, or separates.

Abstract: A fluid system coupling includes an adaptor, a coupler, and an actuation mechanism. The adaptor has an adaptor poppet that is movable between an open position and a closed position. The adaptor poppet has a poppet face that is substantially planar and devoid of any recesses. The coupler has a coupler poppet that is movable between an open position and a closed position. The coupler poppet has a poppet face that is substantially planar and avoid of any recesses. The actuation mechanism selectively moves the poppets from the closed positions to the open positions.

Abstract: A swivel joint includes a tail section and a body portion that define a passageway therethrough and which can rotate relative to one another. One or more seals and bearings can be disposed between the tail section and the body portion. An electrical conductivity grease fitting can be mounted within a bore hole in the body portion. The electrical conductivity grease fitting can have a lubricant passed therethrough to lubricate the bearings. The electrical conductivity grease fitting has a first portion in electrical communication with the body portion and a second portion that is biased into electrical communication with the tail section to maintain electrical conductivity between the tail section and the body portion.

Abstract: A system and method for determining a residual life of a swivel. The method includes determining at least one of an angular rotation, a linear displacement and a rotational direction of at least one swivel and determining rotational count of the at least one swivel based on the determined at least one of the angular rotation, the linear displacement and the rotational direction of the at least one swivel. Further, the method includes indicating a residual life information of the at least one swivel based on the determined rotational count of the at least one swivel. Further, the embodiments herein also provide an electronic device for determining residual life of a swivel.

Abstract: A connection nozzle assembly includes an inner fluid product tube, a tube sleeve secured about the fluid product tube, an outer nozzle sleeve, and a locking mechanism disposed between the fluid product tube and the nozzle sleeve. The nozzle sleeve includes a body portion and a rear portion, each being moveable between a plurality of locking positions. The body portion has at least one J-groove bracket disposed therein and the rear portion has a guide element extending into the bracket. The locking mechanism includes at least one clamping member moveable between a plurality of clamping positions and at least one drop pin moveable between a raised position and a lowered position. The nozzle sleeve is moved between the plurality of locking positions, thereby engaging the locking mechanism to secure the connection nozzle assembly to a receptacle coupling. The connection nozzle assembly can be uncoupled by reversing the nozzle sleeve.

Abstract: Embodiments of the present invention relate to apparatuses, systems, and methods for constructing, installing, and using an inflatable hatch sealing device in environmentally sealing a manhole. In particular, the inflatable hatch sealing device has a sealing assembly with a directed inflatable air bladder, and the sealing assembly is rotatable relative to a contact disc.

Abstract: A fluid system includes a loading arm connected to a swivel joint. A counterbalance mechanism is connected between the loading arm and the swivel joint. An adjustment mechanism adjusts the counterbalance force applied by the counterbalance mechanism to the loading arm. The adjustment mechanism includes a guide plate connected to the swivel joint and includes a guide slot and a straight bore guide. A bracket is movably connected to the guide plate and has one or more apertures and a threaded bore guide. Fasteners extend through the guide slot and the one or more apertures to selectively secure the bracket to the guide plate. A lead screw is disposed at least partially within the straight bore guide and the threaded bore guide. Rotation of the lead screw causes the bracket to move along a length of the lead screw and thereby adjust the counterbalance force.

Abstract: Lock down units and loading arms with lock down units are disclosed. According to one embodiment, a loading arm includes a product delivery pipe pivotally coupled to a product standpipe such that the product delivery pipe is rotatable in a vertical plane. A rocker assembly is coupled to the product delivery pipe. A support arm may be pivotally connected to the product standpipe and slidably coupled to the rocker assembly such that the support arm and the rocker assembly are slidable with respect to one another. The support arm comprises a plurality of slots. A locking pawl is affixed to the rocker assembly and selectively engagable with the slots such that, when the locking pawl is engaged with a slot of the support arm, the locking pawl couples the support arm to the rocker assembly, thereby preventing the product delivery pipe from being raised in the vertical plane.
