| 摘要 |
The present invention relates to a weaklink device for controlled breaking of at least one interconnection (5) on an elongated article (2) such as an umbilical comprising one or more elongated elements such as metal tubes (3,4), said interconnection being of the disconnectable type having two coupler parts (6,7). The weaklink include first retaining means (15,16) for maintaining a controlled interconnection or plug-in/out of the tubes elements (3,4), second retaining means (18) for making the device independent of internal fluid pressure within the tubes elements (3,4) of the elongated article and third retaining means (13) for locking the second retaining means (18), said third retaining means being arranged to yield at a certain longitudinal pull or tension for controlled breaking of at least one interconnection (5) on an elongated article (2) such as an umbilical comprising one or more elongated elements such as metal pipes or tubes (3,4), said interconnection being of the disconnectable type having two coupler parts (6,7).
