Title (EN) FITTING ASSEMBLY FOR DEFORMABLY SEALING CORRUGATED TUBING AND A METHOD FOR USING THE SAME
(FR) ENSEMBLE RACCORD POUR ASSURER L'ETANCHEITE D'UN TUBE ONDULE PAR DEFORMATION ET METHODE D'UTILISATION DE CET ENSEMBLE
Abstract:
(EN) A fitting assembly for corrugated tubing (26) comprising a body (12) having first connecting means (20) , an insert (14) ; locking means (16) having second connecting means (36) ; and a resilient ring (18) . The insert (14) is sealingly engaged with the body (12) and includes a transition area of increased outside diameter. The locking means (20) includes an internally directed lip (42) ; a substantially conical section (38) ; and a retainer disposed between the second connecting means and the conical section (38) . The first and second connecting means (20,36) engage to removably secure the body (12) to the locking means (16) and to slide the ring (18) within the conical section (38) towards the lip (42) forcing the ring (18) to radially contract into a trough of a corrugated tube (26) and sliding the corrugated tube (26) onto the transition area. Further engagement of the first and second connecting means (20,36) causes the ring (18) to push on and collapse a ridge of the corrugated tube (26) against the transition area creating a seal therebetween.
(FR) L'invention concerne un ensemble raccord pour un tube ondulé (26), cet ensemble comprenant un corps (12) comportant un premier moyen de raccordement (20), un insert (14), un moyen de verrouillage (16) comportant un second moyen de raccordement (36), ainsi qu'une bague (18) élastique. L'insert (14) est emboîté de façon étanche dans le corps (12) et il comprend une zone de transition présentant un diamètre extérieur accru. Le moyen de verrouillage (20) comprend une lèvre (42) dirigée vers l'intérieur, une section sensiblement conique (38) et un élément de retenue disposé entre le second moyen de raccordement et cette section conique (38). Le premier et le second moyen de raccordement (20, 36) viennent en prise de façon à fixer le corps (12) au moyen de verrouillage (16) de façon détachable et à faire coulisser la bague (18) à l'intérieur de la section conique (38) en direction de la lèvre (42) pour forcer la bague (18) à se contracter radialement dans un creux du tube ondulé (26) et faire coulisser le tube ondulé (26) sur la zone de transition. Lorsque le premier et le second moyen de raccordement (20, 36) s'emboîtent davantage l'un dans l'autre, la bague (18) fait pression sur une nervure du tube ondulé (26) et la comprime contre la zone de transition, une liaison étanche étant ainsi créée à cet endroit.
