Abstract

L'invention concerne une vanne papillon présentant une étanchéité améliorée, qui comprend un corps de vanne à travers lequel passe le liquide; un disque rotatif disposé sur une tige rotative longitudinale du corps de vanne; et un siège de vanne installé sur une circonférence intérieure du corps de vanne et conçu pour bloquer l'écoulement du liquide lorsqu'il est vient au contact du disque rotatif. Le disque rotatif comprend un moyen de création d'un espace qui délimite un espace vers lequel est (sont) dirigé(s) le liquide ou les corps étrangers coincés entre une extrémité du disque rotatif en contact avec le siège et le siège de vanne. La vanne papillon est conçue pour améliorer l'étanchéité entre un disque rotatif et un siège de vanne en empêchant le passage de granules du liquide ou autres corps étrangers entre le siège de vanne et une extrémité du disque rotatif en contact avec le siège. Elle est également conçue pour améliorer son fonctionnement et sa durée de vie utile en empêchant effectivement la détérioration du siège de vanne et la fuite du liquide contenant de l'air.
