Abstract

L'invention concerne un dispositif de sécurité contre les surpressions. Le carter du dispositif d'arrêt est connecté à une chambre indépendante comportant deux ouvertures se faisant face, que l'on peut obturer par des éléments d'étanchéité se repoussant l'un l'autre au moyen d'un ressort et d'un élément intermédiaire auquel ils sont reliés par un soufflet, la partie de la chambre extérieure au volume formé par les soufflets, l'élément intermédiaire et les éléments d'étanchéité, étant connectée au carter du dispositif d'arrêt. Application aux dispositifs de sécurité contre les surpressions, même faibles, dans les vannes d'arrêt.
