(FR) PROCÉDÉS ET APPAREIL POUR ALIGNER UNE BAGUE DE SIÈGE DANS UNE VALVE
Abstract
(EN)
Methods and apparatus to align a seat ring in a valve are described. An example fluid valve includes a valve body having a curved internal surface to receive a seat ring and a seat ring having a sealing surface to receive a movable control member and a curved surface opposite the sealing surface to engage the curved internal surface of the valve body.
(FR)
L'invention concerne des procédés et un appareil pour aligner une bague de siège dans une valve. Un exemple de valve de fluide comprend un corps de valve ayant une surface interne courbée pour recevoir une bague de siège et une bague de siège ayant une surface d'étanchéité pour recevoir un élément de commande mobile et une surface courbée opposée à la surface d'étanchéité pour enclencher la surface interne courbée du corps de valve.
