Title (EN) COUPLING HAVING SEAL WITH RETRACTING CENTER LEG
(FR) COUPLAGE AYANT UN JOINT D'ÉTANCHÉITÉ AVEC BRANCHE CENTRALE RÉTRACTABLE
Abstract:
(EN) A coupling for joining pipe elements has segments surrounding a central space with cusps which engage lobes of a seal to maintain the segments in spaced apart relation in a preassembled state. While the coupling is in the preassembled state the pipe elements may be inserted into the central space without disassembling the coupling, and portions of the seal adjacent to attachment members on the segments seat within a channel defined by the segments between the cusps. When the seal is compressed between the segments and the pipe elements to form a joint the seal deforms so as to withdraw a center leg of the seal from the flow path defined within the pipe elements.
(FR) La présente invention concerne un couplage destiné à joindre des éléments de tuyau et ayant des segments entourant un espace central avec des cuspides qui viennent en prise avec des lobes d'un joint d'étanchéité pour maintenir les segments dans une relation espacée dans un état pré-assemblé. Pendant que le couplage est dans l'état pré-assemblé, les éléments de tuyau peuvent être insérés dans l'espace central sans démonter le couplage, et des parties du joint d'étanchéité adjacentes à des éléments de fixation sur le siège de segment dans un canal défini par les segments entre les cuspides. Lorsque le joint d'étanchéité est comprimé entre les segments et les éléments de tuyau pour former un joint, le joint d'étanchéité se déforme de façon à retirer une branche centrale du joint d'étanchéité du trajet d'écoulement défini à l'intérieur des éléments de tuyau.
