Title
(EN) PIPE INSERT
(FR) EMBOUT DE TUYAU
Abstract
(EN)
There is provided an insert to be sealingly mounted into a plug hole of a pipe having a sealing area surrounding the plug hole. The insert comprises an internal unit (20) and a fastener (30). The internal unit and the fastener have corresponding cooperating sealing portions and mounting portions. The sealing portion of the internal unit is formed with a flange (22) adapted to be forced into the plug hole. The flange and the sealing portion of the fastener have corresponding sealing surfaces. These surfaces are adapted to sealingly clamp therebetween the sealing area of the pipe, when the insert is mounted into the plug hole. One of the sealing surfaces being in the form of a sealing edge (23) and the other being in the form of a conical surface (32). When the fastener is mounted onto the internal unit, the sealing portions of the internal unit and the fastener form therebetween a chamber. The chamber is in fluid communication with the outside environment, allowing atmospheric pressure within the chamber.

L'invention porte sur un embout destiné à être monté étanche dans le trou de vidange d'un tuyau, trou de vidange qui est entouré d'une zone d'étanchéité. L'embout de l'invention comprend une unité interne et une attache. L'unité interne et l'attache possèdent des parties d'étanchéité et des parties de montage qui coopèrent entre elles. La partie d'étanchéité de l'unité interne est munie d'une collerette d'encastrement qui est apte à être insérée de force dans le trou de vidange. La collerette et la partie d'étanchéité de l'attache possèdent des surfaces d'étanchéité correspondantes, qui sont aptes à serrer de manière étanche entre elles la zone d'étanchéité du tuyau, lorsque l'embout est monté dans le trou de vidange. L'une des surfaces d'étanchéité se présente sous la forme d'une arête d'étanchéité et l'autre, sous la forme d'une surface conique. Lorsque l'attache est montée sur l'unité interne, les parties d'étanchéité de l'unité interne et de l'attache forment une chambre entre elles. La chambre se trouve en communication fluidique avec l'environnement extérieur, permettant d'établir une pression atmosphérique dans la chambre.
