Title (EN) SELF-LOCKING COUPLER
(FR) COUPLEUR À VERROUILLAGE AUTOMATIQUE
Abstract:
(EN) The disclosed embodiments include a self-locking coupler, a method to couple adjacent tubing sections, and a self-locking coupling assembly. In one embodiment, the self-locking coupler includes a coupling shroud having an external interface proximate to a first end of the coupling shroud and a set of collet fingers that extends from the first end of the coupling shroud. The self-locking coupler also includes a locking sleeve having an internal interface that complements the external interface of the coupling shroud. The locking sleeve is movable from a first position on the external interface to a second position on the external interface. As the locking sleeve moves from the first position to the second position, the locking sleeve compresses the set of collet fingers into a cavity of a first seal ring coupled to a first tubing section to secure the coupling shroud to the first tubing section.
(FR) Les modes de réalisation de la présente invention concernent un coupleur à verrouillage automatique, un procédé pour accoupler des sections de tubage adjacentes, et un ensemble de couplage à verrouillage automatique. Dans un mode de réalisation, le coupleur à verrouillage automatique comprend une enveloppe de couplage ayant une interface externe à proximité d'une première extrémité de l'enveloppe de couplage, et un ensemble de doigts de pince qui s'étendent depuis la première extrémité de l'enveloppe de couplage. Le coupleur à verrouillage automatique comprend également un manchon de verrouillage ayant une interface interne qui complète l'interface externe de l'enveloppe de couplage. Le manchon de verrouillage est mobile entre une première position sur l'interface externe et une seconde position sur l'interface externe. À mesure que le manchon de verrouillage se déplace de la première position à la seconde position, le manchon de verrouillage comprime l'ensemble de doigts de pince dans une cavité d'une première bague d'étanchéité accouplée à une première section de tubage pour fixer l'enveloppe de couplage à la première section de tubage.
