Female element for connecting pressurized fluid pipes, has hollow part for protecting joint, where radial thickness for joint in coupled configuration is greater than radial thickness for joint in uncoupled configuration

摘要

The element (3) has a closing valve (35) axially sliding with respect to a pusher (33) for coupling the pusher to the element. An O-ring joint (34) is mounted on the valve and ensures sealing between the pusher and the valve in uncoupled configuration of the element. A hollow part (333) protects the joint and radially interposed between the joint and a main fluid circulation chute in coupled configuration of the element. The radial thickness for the joint in the coupled configuration is greater than the radial thickness for the joint in the uncoupled configuration.
