Title
(EN) PIPE COUPLING INCLUDING A FOLDABLE SEAL FOR RANGE OF PIPE DIAMETERS
(FR) RACCORD DE TUYAU À JOINT D'ÉTANCHÉITÉ PLIABLE POUR UNE PLAGE DE DIAMÈTRES DE TUYAU
Abstract
(EN)
Pipe coupling (10) comprising : a clamp housing (14) comprising at least one end (16) having two opposing clamp members (18) and one or more tightening elements (20) for tightening said clamp members (18) towards each other in a direction transverse to an axial length of said clamp housing (14) so as to apply a radially-inward clamping force on a pipe (22) being clamped in said clamp housing (14); and an at least partially annular seal (12) mounted in said at least one end (16) of said clamp housing (14), said seal (12) having a folded-inwards configuration in which a foldable portion (24) of said seal (12) is folded inwards to create a first inner diameter, and a folded-outwards configuration in which said foldable portion (24) of said seal (12) is unfolded outwards to create a second inner diameter larger than said first inner diameter.
(FR)
L'invention concerne un raccord de tuyau (10) comprenant : un logement de collier de fixation (14) comprenant au moins une extrémité (16) comportant deux organes de collier de fixation opposés (18) et un ou plusieurs élément(s) de serrage (20) destiné(s) à serrer lesdits organes de collier de fixation (18) l'un vers l'autre dans une direction transversale par rapport à une longueur axiale du logement dudit collier de fixation (14) de manière à appliquer une force de serrage dirigée radialement vers l'intérieur sur un tuyau (22) fixé dans ledit logement de collier de fixation (14) ; et un joint d'étanchéité au moins partiellement annulaire (12) monté sur ladite extrémité (16) dudit logement de collier de fixation (14), ledit joint d'étanchéité (12) présentant une configuration pliée vers l'intérieur dans laquelle une partie pliable (24) dudit joint d'étanchéité (12) est pliée vers l'intérieur afin de créer un premier diamètre interne, et une configuration pliée vers l'extérieur dans laquelle ladite partie pliable (24) dudit joint d'étanchéité (12) est dépliée vers l'extérieur afin de créer un second diamètre interne plus grand que ledit premier diamètre interne.
