An apparatus and system are disclosed for fluid transfer. The apparatus includes a fluid nozzle (102) having a nozzle base (106). A poppet (104) is rigidly coupled with the nozzle base (106). The poppet (104) includes a poppet end surface (306). The fluid nozzle (102) also includes a seal ring (118) having a seal ring end surface (308) disposed between a pull-back collar end surface (304) and the poppet end surface (306). The seal ring (118) is moveable between a first position that prevents fluid flow through the fluid nozzle, and a second position that forms an annular fluid outlet that allows fluid flow through the fluid nozzle (102). The fluid nozzle (102) also includes a tubular ball ring (116) disposed around an outer surface of the seal ring (118). The ball ring (116) includes at least one opening (206) for housing a tumbler 404, which is configured to engage a surface feature (408) of a keyed receiver (101). The system includes the keyed receiver (101) and the fluid nozzle (102).

A fluid coupling (10) includes a body (12) defining a passageway (14), a valve member (26) that is selectively movable between a closed position and an open position, and an interface (66) at which the body (12) is connectable to a complementary coupling (10A). An interlock system (124) is configured to permit movement of the valve member (26) from the closed position to the open position when the complementary coupling (10A) is connected to the body (12) at the interface (66), and to prevent movement of the valve member (26) from the closed position to the open position when the complementary coupling (10A) is not connected to the body (12) at the interface (66).
摘要:
A system is provided for transferring fluids such as liquefied natural gas between a floating transport vessel and a floating storage vessel utilizing a transfer vessel to deploy, operate and return a fluid conduit to the storage vessel. The fluid is transferred through at least one submerged-subsea catenary flexible conduit, at least one floating flexible conduit, or any combination thereof. A transfer vessel, including a releasable mooring system, is provided for deploying the conduit from the storage vessel to the transport vessel, mooring with a transport vessel, maintaining a unified connection during fluid transfer, releasing the mooring once fluid transfer is completed, returning to and parking on the storage vessel, and storing the conduit between fluid transfers. The transfer vessel and releasable mooring system allows safe, controlled operation and fluid transfer in open sea conditions.

A dispense head assembly include a bung adapter (200), a body receiver (300), and a dispensing body (500). The bung adapter (200) inserts into a drum (20). The body receiver (300) selectively inserts into the bung adapter (200), and the dispensing body (500) selectively inserts into the body receiver (300). A single, unobstructured, uniform-diameter flowpath routes fluid from the drum (20) into a chamber (560) within the body receiver (300). A moveable piston (700) within the chamber selectively blocks fluid flow between the fluid flowpath and a dispense opening (566) on the dispensing body (500). The body receiver (300) and the dispensing body (500) are key matched, for safe and rapid coupling and decoupling.
摘要:
This invention concerns a coupling device for secure and simple transfer of gaseous and/or liquid fluids, particularly for filling vehicle fuel tanks, which consists of a tubular housing (11); an exterior sliding shell (18) which can be displaced with respect to the housing; several radially-movable locking elements affixed to the housing, in particular, a collet (15) which can be sprayed out with a section which engages for connecting to a correspondingly-shaped connection nipple (30); and a sealing piston (22) which can slide axially in the housing to seat on the connecting nipple (30). To accomplish this, the invention proposes that an axially displaceable spring-loaded ring piston (40) be added to the sealing piston (22) which, in the uncoupled position of the coupling device for rapid connection (10), holds the sealing piston (22) in a retracted position and, when put under pressure, is displaceably seated relative to the sealing piston (22).

The device comprises a cylinder (15, 49) wherein a piston under pressure may move in one direction or the other. On the piston, there is provided a clamp device configured as jaws (32) which are compressible inwardly and securable in a spaced apart position. A sleeve (4) is slidingly arranged on the outer envelope (41, 42) of the cylinder; it may take a plurality of positions: it may clamp the jaws in the first position, space the jaws apart in the second position and supply compressed air to a connection in the third position.
