Abstract

L'invention a trait aux accessoires de canalisations pour fluides. Elle a pour objet un joint annulaire d'étanchéité pour robinets pour températures élevées, en particulier robinets ou vannes dans des circuits de réacteur, muni d'un dispositif soulevant le joint d'étanchéité de la pièce de fermeture lors de la manoeuvre de celle-ci, caractérisé en ce que le joint annulaire d'étanchéité 3 est suspendu à un certain nombre de tiges métalliques 4 uniformément réparties sur sa périphérie, qui sont reliées à leur tour au boîtier par l'intermédiaire d'éléments métalliques 5 fléchissant élastiquement. Application notamment aux circuits de réacteur.
