Title (EN) PRESSURE CONTROL DEVICE
(FR) DISPOSITIF DE RÉGLAGE DE PRESSION
Abstract: front page image
(EN)A pressure control device for isolating a section of a conduit is described. The device comprises a support member, a flexible cup member mounted to the support member, a first swellable element, the first swellable element adapted, upon activation by an activation fluid, to urge a first portion of the cup member outwards into engagement with a conduit surface and at least one bypass arranged to permit the activation fluid to bypass the swellable element and build up behind a second portion of the cup member.
(FR)L'invention porte sur un dispositif de réglage de pression pour l'isolement d'une partie d'une conduite. Le dispositif comprend un élément support, un élément coupelle souple monté sur l'élément support, un premier élément gonflable, le premier élément gonflable étant conçu pour, lors de l'activation par un fluide d'activation, presser une partie de l'élément coupelle vers l'extérieur en contact avec une surface de la conduite et au moins une dérivation disposée pour permettre au fluide d'activation de contourner l'élément gonflable et de s'accumuler derrière une seconde partie de l'élément coupelle.
