Abstract
Dans cette vanne, pour installer la bague de siège, des encoches espacées en forme de croissant sont ménagées dans les rails de guidage coaxialement avec le passage d'écoulement et les contre-alésages de la bague de siège. Ces encoches ont un diamètre un peu plus grand que le diamètre des bagues de sièges. Grâce à cette construction, il est possible d'abaisser la bague de siège entre les rails de guidage et d'amener axialement cette bague à travers l'espace existant entre les encoches, dans sa position de travail. On peut ainsi faire des économies sur les dimensions et le poids du corps de vanne. Application aux vannes de grand diamètre pour pressions élevees.
