| 摘要 |
The invention concerns a coupling comprising a male element (3) and a female element (5) adapted to be axially fitted and interlocked one inside the other. A locking mechanism (37, 55) axially immobilizes the male element in a coupling position and a temporarily retaining mechanism (37, 55, 59) immobilizes the male element, after its release by the locking mechanism, in a position for flushing the pipe (C1) connected to the male element. The locking mechanism is controlled by a maneuvering sleeve (53) sliding around a body of the female element. When it retains the male element in flushing position, the temporarily retaining mechanism is subjected to a first load (E1) derived from the pressure (P) of the fluid flowing (F) from the male element outwards and to a second load (E2), opposite to the first, exerted by elastic return means (57) which, when the pressure (P) reaches a safety threshold, moves the mechanism into a configuration releasing the male element. |
