Abstract

L'invention concerne un robinet-vanne à double opercule. Le robinet-vanne 10 comporte un corps 12 dans lequel sont formés des passages d'écoulement coaxiaux 36, 38 et une chambre centrale de commande renfermant un obturateur 26 en forme de coin à deux opercules 100, 102 qui sont maintenus espacés l'un de l'autre par une entretoise annulaire 120 amovible emprisonnée avec jeu entre eux de sorte que, lorsque les surfaces d'appui 104 des opercules et des sièges 56 sont réusinées après usure, l'enlèvement de matière qui en résulte peut être compensé en remplaçant la bague 120 par une bague plus large L'invention est applicable, notamment, aux robinets-vannes à double opercule pour pression élevée.
