Title (EN) TELESCOPING DOUBLE BLOCK AND BLEED PLUG
(FR) DOUBLE BLOC TÉLESCOPIQUE ET BOUCHON DE PURGE
Abstract:
(EN) A plugging device for double blocking a section of pipeline or piping and method for its use includes a first and second sealing element and at least one cylinder that is extendable along an axial direction of the pipe between a retracted first position and an extended second position. A means for actuating the cylinder, such as a fluid power source, is provided. When the cylinder is in the extended second position, the sealing element sealably engages an opposing cut end of the pipe. The sealing element is an elastomeric sealing element and may be cup-shaped, convex-shaped, or cork-shaped.
(FR) L’invention concerne un dispositif de bouchage pour bloquer doublement une section de pipeline ou de tuyauterie et un procédé pour son utilisation. Il comprend un premier et un second élément d’étanchéité et au moins un cylindre, qui est extensible le long d’une direction axiale du tuyau, entre une première position rétractée et une seconde position étendue. Un système d’actionnement du cylindre, comme une source d’alimentation en fluide, est fourni. Quand le cylindre est dans la seconde position étendue, l’élément d’étanchéité met en prise de manière étanche une extrémité de découpe opposée du tuyau. L’élément d’étanchéité est un élément d’étanchéité élastomère et peut être en forme de tasse, de forme convexe, ou en forme de bouchon.
