<p>A connector for piping is described of the type comprising two tubular fitti ng parts (1, 2) and quick-coupling and quick release means (15) having a plurality of locking segments (16) circumferentially distributed in a plane perpendicular to the axis of said fitting parts (l, 2) and housed in radial slots (17) of an axial projecting portion (6) of a first fitting part (2) that, during the coupling stage, is superimposable to a corresponding projecting axial portion (5) of the second fitting part (1). A revolving rin g (18) can be controlled to rotate in order to work on said locking segments (16) so as to push them into at least one radial seat (33) of said projectin g. portion (5) of the second part of joint (1) or to house them in its own radi al seat (34), respectively for the coupling and the uncoupling of said fitting parts (1, 2). Two independent by operable hydraulic cylinders (19) are arranged substantially at 180~ from each other in the rotation plane of the revolving ring (18) and they react, each one, between a first lever (22) fastened to the first fitting part (2) and a second lever (23) fastened to t he revolving ring (18). Said first lever (22) is made up of a radially more external part (24) and of a radially more internal part (25) that are connected with each other by an articulation (26) which is modifiable in ord er to be able to assume a first operating condition for the complete mutual locking of the two parts (24, 25) of the first lever (22) and a second operating condition of consent to the rotation of the radially more external part (24) of the first lever (22) in direction of approach to the second lev er (23).</p> |
