Title
(EN) STRUCTURE FOR AN OPENING OR A DUCT AND A METHOD FOR OBSTRUCTING FLOW THROUGH AN OPENING OR DUCT WITH THE AID OF THE STRUCTURE
(FR) STRUCTURE POUR UNE OUVERTURE OU UN CONDUIT ET PROCÉDÉ POUR OBSTRUER L'ÉCOULEMENT À TRAVERS UNE OUVERTURE OU UN CONDUIT À L'AIDE DE LA STRUCTURE
Abstract
(EN)
The invention relates to a structure (10) for an opening (100) or duct (102), which includes - a frame structure (12) arranged in an opening (100) or duct (102), - a flow-obstructing structure (14) allowing the pas sage of a medium flow and comprising surfaces (15) for interrupting the medium flow if a selected criterion is fulfilled by sealing the flow-obstructing structure (14) by means of an obstructing material (16) expanding on the surfaces (15), - an actuating device (18) for initiating a sealing of the flow-obstructing structure (14), - a release device (25) for deploying the actuating device (18) in conjunction with a selected criterion. - a pressurized tank (20) for the obstructing material (16), - a valve (22) connected to the pressurized tank (20) and adapted to be deployed with the actuating device (18), and - a supply duct (24) comprising discharge openings (26) and arranged so as to extend to a connection of the flow- obstructing structure (14) in order to transfer obstructing material (16) present in the pressurized tank (20) from the pressurized tank (20) to the surfaces of the flow-obstructing structure (14) when a selected criterion is fulfilled. A further object of the invention is a method for preventing a flow through an opening (100) or duct (102) by means of the structure (10).
(FR)
L'invention porte sur une structure (10) pour une ouverture (100) ou un conduit (102), qui comprend-une structure de cadre (12) disposée dans une ouverture (100) ou un conduit (102),-une structure d'obstruction d'écoulement (14) permettant le passage d'un écoulement moyen et comprenant des surfaces (15) pour interrompre l'écoulement moyen si un critère sélectionné est rempli par scellement étanche de la structure d'obstruction d'écoulement (14) au moyen d'un matériau d'obstruction (16) s'étendant sur les surfaces (15),-un dispositif d'actionnement (18) pour initier une étanchéité de la structure d'obstruction d'écoulement (14),-un dispositif de libération (25) pour déployer le dispositif d'actionnement (18) conjointement avec un critère choisi. -Un réservoir sous pression (20) pour le matériau d'obstruction (16),-une vanne (22) reliée au réservoir sous pression (20) et apte à être déployée avec le dispositif d'actionnement (18), et-un conduit d'alimentation (24) comprenant des ouvertures de décharge (26) et agencé de manière à s'étendre jusqu'à une connexion de la structure d'obstruction d'écoulement (14) afin de transférer un matériau d'obstruction (16) présent dans le réservoir sous pression (20) depuis le réservoir sous pression (20) vers les surfaces de la structure d'obstruction d'écoulement (14) lorsqu'un critère sélectionné est satisfait. Un autre objet de l'invention est un procédé pour empêcher un écoulement à travers une ouverture (100) ou un conduit (102) au moyen de la structure (10).
