Abstract

a. Dispositif pour obturer deux conduites coaxiales de section circulaire et annulaire disposées dans un carter extérieur tubulaire. b. Dispositif caractérisé par un corps intérieur disposé dans un élément tubulaire intérieur de section circulaire dont l'enveloppe est élargie uniformément autour de l'axe, ce corps intérieur étant cylindrique dans sa partie médiane et allant ensuite en se rétrécissant avec une forme conique de chaque côté, les parties coniques constituant des éléments d'obturateurs agissant en sens inverse sur des sièges de l'enveloppe c. Dispositif applicable à des conduites de gaz chauds, notamment dans un réacteur nucléaire.
