Abstract

Dispositif de sécurité à fonctionnement automatique Un clapet auto-centreur est verrouillé, en position de fermeture, par la pression amont; une biellette coudée, pivotant sur un axe passant par son coude, est articulée d'une part sur la tige du clapet et d'autre part sur la membrane, une tige de manoeuvre de la membrane porte une pièce munie de deux ergots; et deux rampes constituent des chemins de glissement pour les ergots. Contrôle des canalisations de fluide
