(FR) DISPOSITIF DE BOÎTIER PLIABLE DESTINÉ À ÊTRE UTILISÉ POUR RÉGULER UN ÉCOULEMENT
Abstract
(EN)
A collapsible casing device, comprising an insert housing, said insert housing having an outer surface and an inner surface, said outer surface fluidly isolated from an external environment, said inner surface having a profile, and a connection between said outer surface and said inner surface, wherein said connection is capable of fluidly connecting to a tubular element; a deformable insert, said deformable insert having an inner surface and an outer surface, said outer surface fitting within said profile of said insert housing, said inner surface capable of containing a fluid and having a first inner diameter, said deformable insert having properties that are conducive to deformation; an explosive material that generates a pressure pulse in response to an activation signal, said explosive material having an inner surface and an outer surface and a composition, said outer surface fitting within said profile of said insert housing, said inner surface external to said outer surface of said deformable insert; and a trigger, said trigger capable of generating said activation signal.
(FR)
La présente invention se rapporte à un dispositif de boîtier pliable qui comprend un logement de pièce rapportée, ledit logement d'insertion présentant une surface externe et une surface interne, ladite surface externe étant isolée fluidiquement d'un environnement extérieur, ladite surface interne présentant un profil et une connexion entre ladite surface externe et ladite surface interne, ladite connexion pouvant être raccordée fluidiquement à un élément tubulaire ; une pièce rapportée déformable, ladite pièce rapportée déformable présentant une surface interne et une surface externe, ladite surface externe s'adaptant dans ledit profil dudit logement de pièce rapportée, ladite surface interne pouvant contenir un fluide et présentant un premier diamètre interne, ladite pièce rapportée déformable ayant des propriétés qui permettent une déformation ; un matériau explosif qui génère une impulsion de pression en réponse à un signal d'activation, ledit matériau explosif présentant une surface interne et une surface externe et une composition, ladite surface externe s'adaptant dans ledit profil dudit logement de pièce rapportée, ladite surface interne étant externe à ladite surface externe de ladite pièce rapportée déformable ; et un dispositif de déclenchement, ledit dispositif de déclenchement pouvant générer ledit signal d'activation.
