CONNECTING DEVICE FOR FLEXIBLE PIPES

摘要

A connecting device for flexible pipes, including: a supporting body, having at least one tubular portion which may be inserted in a relative flexible pipe; a seal ring, positioned around the tubular portion of the supporting body and switchable between an engaging position wherein it retains the flexible pipe on the tubular portion and a releasing position wherein it disengages the flexible pipe; and a mechanism for moving the seal ring for switching the ring between the engaging position and the releasing position; the tubular portion of the supporting body also including at least one protruding element, extending from the outer surface of the tubular portion along the entire transversal extension of the portion; the protruding element being interposed between two adjacent zones of the tubular portion having different transversal cross-sectional dimensions.

1. A connecting device for flexible pipes, comprising:
a supporting body, having at least one tubular portion which may be inserted in a relative flexible pipe; a seal ring, extending axially between a first and a second edge, positioned around the tubular portion of the supporting body and switchable between an engaging position wherein it retains the flexible pipe on the tubular portion and a releasing position wherein it disengages the flexible pipe; and means of moving the seal ring for switching the ring between the engaging position and the releasing position; wherein the tubular portion of the supporting body comprises at least one protruding element, extending from the outer surface of the tubular portion along the entire transversal extension of the portion; the protruding element being interposed between two adjacent zones of the tubular portion having different transversal cross-sectional dimensions; characterised in that an outer surface of the ring has a first portion and a second portion arranged one after another along an axial extension of the ring and connected at a relative intermediate zone of the selfsame outer surface; the first portion having a truncated cone shape, extending away from the second edge with increasing cross-section and the second portion extending between the intermediate zone and the first edge forming a substantially cylindrical profile.
