Problems solved by technology
[0006] The only possible inconvenience is the theoretically determinable difficulty in loosening due to the non-operation of the hydraulic cylinders used to move the rotating ring, for example due to the long-term use of the connector in the open sea or due to the transportation of oil at very low temperatures product while freezing

Embodiment Construction
[0018] The connector shown in the accompanying drawings comprises (FIG. 1) a first tubular pipe member 1 and a second tubular pipe member 2, each consisting of a corresponding body 3, 4 and a corresponding axial projection 5 , 6 components. The bodies 3 , 4 serve to fasten the respective pipes 9 , 10 to be connected by means of bolts 7 , 8 . The protrusions 5, 6 can then be inserted into each other so as to define a single cylindrical channel 11 for fluid flow from one duct to the other. An axially displaceable ring 12 is accommodated in an axially forward recess 13 of the protrusion 6 of the pipe 2 and is urged by a spring 14 towards the opposite protrusion 5 of the pipe 1 .
[0019] The interconnection of the two pipes 1 and 2 and thus the connection of the two pipes 9 and 10 is realized by a quick connection and quick release device 15 comprising ( figure 2 ) a plurality of locking blocks 16 distributed circumferentially in a plane perpendicular to the axis of the channel...

A connector for piping is described of the type comprising two tubular fitting parts and quick-coupling and quick release means having a plurality of locking segments circumferentially distributed in a plane perpendicular to the axis of said fitting parts and housed in radial slots of an axial projecting portion of a first fitting part that, during the coupling stage, is superimposable to a corresponding projecting axial portion of the second fitting part. A revolving ring can be controlled to rotate in order to work on said locking segments so as to push them into at least one radial seat of said projecting portion of the second part of joint or to house them in its own radial seat, respectively for the coupling and the uncoupling of said fitting parts. Two independent by operable hydraulic cylinders are arranged substantially at 180 DEG from each other in the rotation plane of the revolving ring and they react, each one, between a first lever fastened to the first fitting part and a second lever fastened to the revolving ring. Said first lever is made up of a radially more external part and of a radially more internal part that are connected with each other by an articulation which is modifiable in order to be able to assume a first operating condition for the complete mutual locking of the two parts of the first lever and a second operating condition of consent to the rotation of the radially more external part of the first lever in direction of approach to the second lever.
Description
technical field [0001] The invention relates to a quick-connect and quick-release safety connector for pipelines. Background technique [0002] In many occasions, it is necessary to realize quick connection and quick separation of two pipes. This is the case, for example, of pipelines for transporting liquid petroleum products under harsh - sometimes dangerous environmental conditions such as in the open sea or from sea to land and vice versa. [0003] For this reason, there are known quick-connect and quick-release connector devices capable of safely and quickly connecting and disconnecting two pipes. [0004] One such device is described in EP-A-0153773, which comprises two tubular pipes (joints) fastenable to respective pipes to be connected and quick-connect and quick-release means for said pipes. The quick-connect and quick-release device comprises a plurality of radial grooves distributed circumferentially in a plane perpendicular to the axis of the pipe and radially...
