Abstract
Procédé pour assurer l'étanchéité dans un robinet à soupape, dans lequel la surface d'étanchéité d'un clapet mobile est inclinée par rapport à la direction de déplacement du clapet. Au moins la partie 5 du clapet 1 portant la surface d'étanchéité est réalisée en une matière plus dure que celle du siège 6, de sorte que sous l'effort normal de fermeture du robinet, le clapet 1 peut engendrer dans le siège 6 des déformations plastiques par lesqelles la forme du siège 6 s'adapte à celle de la surface d'étanchéité du clapet 5. L'invention permet la conservation de l'étanchéité, indépendamment de l'usure des surfaces du siège et du clapet.
