Abstract

Le raccord est du type composé d'une tulipe 11 dans laquelle s'adapte une virole 12 avec collerette 13 s'adaptant à l'extrémité du tuyau 14, celui-ci étant serré par une bague 17 entrant dans la tulipe Il et serrant le tuyau. Le raccord est caractérisé par le fait que la virole 12 a sa partie crantée biconique, en forme d'olive et qu'on prévoit un joint torique élastique 15 coincé entre le fond de la tulipe Il, le pourtour de l'extrémité du tuyau 14 et la bague 17, celle-ci ayant un profil intérieur conique lisse correspondant à celui de la virole 12. Application à tout raccord, notamment ceux de liquide ou de gaz.The fitting is of the type composed of a tulip 11 in which fits a ferrule 12 with collar 13 adapting to the end of the pipe 14, the latter being clamped by a ring 17 entering the tulip II and tightening the pipe. The connection is characterized by the fact that the ferrule 12 has its biconical notched part, in the form of an olive and that an elastic O-ring 15 is provided wedged between the bottom of the tulip II, the periphery of the end of the pipe 14 and the ring 17, the latter having a smooth conical internal profile corresponding to that of the ferrule 12. Application to any connection, in particular those of liquid or gas.
