Title
(EN) FITTING FOR CONNECTING PIPES, IN PARTICULAR FLEXIBLE PIPES
(FR) RACCORD POUR RACCORDER DES TUYAUX, EN PARTICULIER DES TUYAUX FLEXIBLES
Abstract
(EN)
The present invention relates to a fitting (1) for connecting pipes (T), in particular flexible pipes, comprising a first tubular element (3), provided with a first inlet/outlet opening (3a) and defining at its interior a first duct (3b), and a second tubular element (4), provided with a second inlet/outlet opening (4a) and defining at its interior a second duct (4b); the two tubular elements are connected to each other in a manner such that the first and the second duct are in communication. The fitting comprises a first bushing (11), associated with the first tubular element in order to externally surround it and create an annular housing (12), which can operate in an insertion configuration, in which it allows the insertion of a pipe (T) in the annular housing, and a clamping configuration, in which it presses and locks the pipe in a fluid-tight manner. The fitting comprises a first bushing-holder (30), externally associated with the first tubular element and configured for mounting the first bushing so that it defines the annular housing, comprising a seal portion (31) externally wound around and in contact with a seal sector (40) of the first tubular element. The seal portion (31) is interposed between a portion of the pipe, inserted in the annular housing, and the seal sector (40), and attains a fluid-tight gasket when the first bushing is in clamping configuration, preventing the leakage of fluid between the first duct and the exterior of the fitting.
(FR)
La présente invention concerne un raccord (1) pour raccorder des tuyaux (T), en particulier des tuyaux flexibles, lequel raccord comprend un premier élément tubulaire (3), comportant une première ouverture d'entrée/sortie (3a) et définissant en son sein un premier conduit (3b), et un second élément tubulaire (4), comportant une seconde ouverture d'entrée/sortie (4a) et définissant en son sein un second conduit (4b) ; les deux éléments tubulaires sont raccordés l'un à l'autre de telle sorte que les premier et second conduits sont en communication. Le raccord comprend une première douille (11), associée au premier élément tubulaire pour l'entourer extérieurement et créer un logement annulaire (12), qui peut fonctionner dans une configuration d'insertion, dans laquelle il permet l'insertion d'un tuyau (T) dans le logement annulaire, et une configuration de serrage, dans laquelle il presse et verrouille le tuyau de manière étanche aux fluides. Le raccord comprend un premier support de douille (30), associé, à l'extérieur, au premier élément tubulaire et conçu pour monter la première douille de telle sorte qu'elle définit le logement annulaire, comprenant une partie d'étanchéité (31) enroulée extérieurement autour d'un secteur d'étanchéité (40) du premier élément tubulaire et en contact avec ledit secteur. La partie d'étanchéité (31) est intercalée entre une partie du tuyau, insérée dans le logement annulaire, et le secteur d'étanchéité (40), et atteint un joint étanche au fluide lorsque la première douille est en configuration de serrage, empêchant la fuite de fluide entre le premier conduit et l'extérieur du raccord.
