Abstract

Obturateur arrière en deux parties pour un robinet à tournant, comprenant un corps d'étanchéité d'obturateur arrière et un écrou de retenue d'obturateur arrière. L'écrou de retenue d'obturateur arrière permet de fixer le corps d'étanchéité d'obturateur arrière à un robinet à tournant tout en supportant fermement le corps d'étanchéité d'obturateur arrière. Un espace entre le bord externe de l'écrou de retenue d'obturateur arrière et le corps d'étanchéité d'obturateur arrière permet au corps d'étanchéité d'obturateur arrière de se plier et de se dilater en même temps que le corps du robinet à tournant. Cette caractéristique permet aux composants d'étanchéité de l'obturateur arrière de ne pas subir de tension et augmente ainsi sa durée de vie.
