Title (EN) FAST CLOSING VALVE FOR GASEOUS AND LIQUID MEDIUM
(FR) SOUPAPE A FERMETURE RAPIDE POUR MILIEU GAZEUX ET LIQUIDE
Abstract:
(EN) A fast closing valve for gaseous and liquid medium closes, against a resilient force, upon the occurrence of a sudden pressure difference in the conduit, specially aeration conduits for use in anti-aircraft protection shelters. The main partis a valve-flap having the form of a dihedron (10), which is mounted, pivoting easily within a chamber (9) about the axis of the vertex of the dihedron (axis 11). On either side of the valve flap (10a, 10b) are associated deviation openings (7, 8) of the chamber (9) which will be closed alternately by the pivoting of the flap (10). The flap (10) is normally held in a stable open position by a spring arrangement (14) until one or the other of the flap sides is subject to a pressure wave causing the closure of one or the other of the openings (7, 8).
(FR) Une soupape a fermeture rapide pour milieu gazeux et liquide ferme, a l"encontre d"une force elastique, lors d"une soudaine difference de pression dans la conduite, specialement pour l"emploi dans les conduites d"aeration des abris de protection antiaerienne. La partie essentielle est un clapet en forme de diedre (10), qui est fixe, basculant facilement dans une chambre (9) sensiblement autour de l"axe du sommet du diedre (axe 11). Aux deux cotes du clapet (10a, 10b) sont adjointes des ouvertures de deviation (7, 8) de la chambre (9) qui seront alternativement fermees par le mouvement de basculement du clapet (10). Le clapet (10) est maintenu normalement dans une position ouverte stable par un agencement a ressort (14) jusqu"a ce que l"un ou l"autre des cotes du clapet soit soumis a une onde de pression entrainant la fermeture de l"une ou l"autre des ouvertures (7, 8).
