A connector for piping is described of the type comprising two tubular fitting 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 ring (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 projecting. portion (5) of the second part of joint (1) or to house them in its own radial 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 the 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 order 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 lever (23).
L'invention concerne un connecteur pour tuyauterie du type comprenant deux raccords (1, 2) tubulaires et des organes de couplage et de desserrage rapides (15) dotés de plusieurs segments de blocage (16) répartis de manière périphérique dans un plan perpendiculaire à l'axe des raccords (1, 2) et logés dans des fentes (17) radiales d'une partie en saillie axiale (6) d'un premier raccord (2) qui, lors du couplage, peut se superposer à une partie en saillie (5) axiale correspondante du second raccord (1). Une bague tournante (18) peut être commandée en rotation afin d'agir sur lesdits segments de blocage (16) et de les pousser à l'intérieur d'au moins un siège radial (33) de ladite partie en saillie (5) du second raccord (1) ou de les loger à l'intérieur de son propre siège radial (34), respectivement pour le couplage et le découplage desdits raccords (1, 2). Deux cylindres hydrauliques (19) indépendants, placés sensiblement à 180· l'un de l'autre dans le plan de rotation de la bague tournante (18), réagissent, chacun, entre un premier levier (22) fixé au premier raccord (2) et un second levier (23) fixé à la bague tournante (18). Le premier levier (22) est composé d'une partie radialement plus extérieure (24) et d'une partie radialement plus intérieure (25) qui sont raccordées par une articulation (26) modifiable de façon à pouvoir supporter une première condition de fonctionnement du blocage mutuel complet des deux parties (24, 25) du premier levier (22), et une seconde condition d'acceptation de fonctionnement de la rotation de la partie radialement plus extérieure (24) du premier levier (22) en direction du second levier (23).
