Patent

CA 2483754

There is disclosed a pipe coupling (13) for coupling the ends of pipe sections (10 and 11) together end to end. The coupling includes a barrel member (19) adapted to bridge and surround the ends of the pipe sections to be coupled, and, together with coupling members (20), adapted to engage the ends of the barrel sections, and elastomeric sealing rings (21) adapted to be forced by the coupling members into the ends of the barrel member and expanded radially outwardly and inwardly into tight sealing engagement within the end of the barrel member and around the circumferences of the pipe sections being coupled. Substantially tangentially extending bolts (22) are utilised to couple the respective coupling members to the barrel member, and means (29, 30) on the inside of the coupling members, and on the outside of the barrel member, to interact and progressively twist the coupling members along the barrel member to force the sealing rings into tight sealing engagement with the inside of the barrel member and around the circumference of the pipe sections being coupled. There is also disclosed a coupling which has a barrel member which forms part of one of the pipe sections to be joined and only one coupling member and sealing ring is used to couple the barrel member to the other pipe section.

L'invention concerne un raccord de tuyau (13) destiné à raccorder les extrémités des sections de tuyaux (10, 11) ensemble extrémité à extrémité. Ledit raccord comprend un élément cylindre (19) conçu pour coupler et entourer les extrémités des sections de tuyaux à raccorder. Ledit élément cylindre (19) associé aux éléments de raccord (20) est conçu pour mettre en contact les extrémités des sections de cylindre. Ledit raccord comprend des anneaux de scellement (21) conçus pour être poussés par les éléments de raccord dans les extrémités de l'élément cylindre et expansés radialement à l'extérieur et à l'intérieur en prise hermétique étanche à l'intérieur de l'extrémité de l'élément cylindre et autour de la circonférence des sections de tuyaux raccordées. Des boulons (22) s'étendant de manière tangentielle sont utilisés pour coupler les éléments de raccord respectifs audit élément cylindre. Ledit raccord comprend des moyens (29, 30) situés à l'intérieur des éléments de raccord et à l'extérieur de l'élément cylindre, qui interagissent et déforment progressivement les éléments de raccord le long de l'élément cylindre pour pousser les anneaux de scellement en prise hermétique étanche avec l'intérieur dudit élément cylindre et autour de la circonférence des sections de tuyaux raccordée. L'invention concerne un raccord présentant un cylindre qui forme une partie d'une des sections de tuyaux destinés à être joints et uniquement un élément de raccord et un anneau de scellement sont utilisés pour coupler l'élément cylindre à l'autre section de tuyaux.
