Patent

CA 2566697

A preassembled mechanical pipe coupling having spacers is disclosed. The coupling has a plurality of interconnectable segments that straddle the ends of pipe elements to be joined. The segments have arcuate surfaces that engage outer surfaces of the pipe elements. Spacers, positioned between the segments, maintain them in spaced apart relation sufficient to allow the pipe elements to be inserted between the segments. The segments have adjustably tightenable connection members for connecting the segments and drawing them to one another. When the connection members are tightened and the effect of the spacers is overcome, the arcuate surfaces are brought into engagement with the outer surfaces of the pipe elements.

L'invention concerne un raccord de tube mécanique pré-assemblé doté d'entretoises. Ledit raccord a plusieurs segments interconnectables à cheval sur les extrémités des éléments tubulaires à raccorder. Lesdits segments présentent des surfaces courbes en prise avec les surfaces externes des éléments tubulaires. Des entretoises, posées entre les segments, maintiennent ceux-ci suffisamment espacés de façon à permettre aux éléments tubulaires d'être insérés entre lesdits segments. Ces segments ont des éléments de raccord que l'ont peut serrer de manière réglable pour raccorder lesdits segments et les tirer les uns vers les autres. Une fois les éléments de raccord serrés et l'effet des entretoises surmonté, les surfaces courbes sont amenées en contact avec les surfaces externes des éléments tubulaires.
