摘要:
A subsea coupling arrangement (1) for connecting an end section (2) of a flexible conduit to a structural element (3), comprising: - an end fitting (6) mounted to the end section; - clamping elements (9) for clamping together a coupling member (7) of the end fitting and a coupling member (8) of the structural element; - a locking and release mechanism (12) which is manoeuvrable from a locking position, in which the coupling members are prevented from being disengaged from each other, to a releasing position, in which the coupling members are allowed to be disengaged from each other; and - at least one elongated pulling member (13a) which is configured to exert a pulling force on the locking and release mechanism and thereby strive to manoeuvre it from the locking position to the releasing position when the flexible conduit is subjected to an external force that causes a stretching of the end section.

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).

This invention relates to a hydraulic system comprising a hydraulic cross connection (90), housed in a housing case (99) to be mounted on a rear planar support (98), comprising inlet and outlet ducts (70, 71), at least one tubular element (105, 106) insertable in each one of said ducts (70, 71), and at least one quick coupling removable hook (91; 991), configured to be inserted in a seat (100) obtained on an outer wall of each one of said ducts (70, 71), the hydraulic system being characterised in that said at least one quick coupling removable hook (91; 991) is configured to be posteriorly inserted in the seat (100) and it comprises at least one rear arm (95; 995), and in that the housing case (99) is shaped so that a distance separating the seat (100) of each one of said ducts (70, 71) from the rear planar support (98) is such that said at least one removable hook (91; 991) is removable from the seat (100) and said at least one tubular element (105, 106) is extractable from the inlet or outlet duct (70, 71) to which the seat (100) belongs only when the housing case (99) is not mounted on the rear planar support (98). This invention further relates to the related kit of hydraulic accessories and to the related hydraulic system, as well as to a mixing apparatus comprising such hydraulic system.

The invention is a safety lock that keeps the cam lock arms of a female cam lock hose fitting from accidentally opening. It is made of a resilient material and snaps in place over the cam arms from either side of the fitting and can be installed and removed with one gloved hand. It snaps in place to provide a tactile indication of proper placement. The safety lock has a low profile so that it can remain on the fitting when placed in hose tubes and trays. It also protects the cam arms split rings on the ends of the cam arms from damage. An aperture in the leg of the safety lock allows a tether or cable loop to be attached.
摘要:
Die Erfindung betrifft eine Sicherungseinrichtung für eine insbesondere Pres s Verbindung zwishen einer Schlauchleitung (1) und einer Anschlussarmatur (3;5), umfassend ein Fangseil (7), eine Befestigungslasche (13) sowie ein schellenartiges Seillager (9) mit Öffnung oder Bohrung (11), wobei die Befestigungslasche (13) am schlauchleitungsfernen Ende mit der Anschlussarmatur (3, -5) verbunden und das Fangseil (7) am Seillager fixierbar ist. Erf indungsgemäss ist das Fangseil (7) als sich kreuzende Schlaufe um die Schlauchleitung (1) gelegt. Die Seilenden sind kreuzend durch die Bohrung (11) des Seillagers (9) geführt und die hindurch geführten Seilenden an der Befestigungslasche (13) fixiert, wobei das Seillager sich in einem vorgegebenen Abstand vom schlauchleitungsnahen Ende der Anschlussarmatur (5) auf der Schlauchleitung (1) und die Fangseilschlaufe (14) hinter dem Seillager (9), auf der der Anschlussarmatur (5) abgewandten Seite befinden.
摘要:
The invention relates to a coupling for connecting hoses or the like for a medium under pressure. The coupling comprises a female part (1) and a nipple (2) insertable therein, as well a ball lock means (5, 6) for locking the nipple (2) in its inserted position in the female part (1). The female part (1) is provided with an axially displaceable valve element (9) which is moved from a closed position in contact with a valve seat (10) in the female part (1) to an open position spaced from the valve seat (10) when the nipple (2) is inserted into the female part (1). The invention is characterized in that at least one blocking means (14-16) is arranged in the female part (1) to block the nipple (2), when the ball lock means (5, 6) are released and the coupling is under pressure. In an intermediate position with the valve element (9) in contact with the valve seat (10) and the interior of the nipple (2) in communication with the surrounding atmosphere until the pressure in the nipple (2) has dropped below a predetermined level.
