Abstract

L'invention concerne des perfectionnements aux vannes du type vanne papillon. Selon l'invention, la vanne comporte un siège formé d'une couronne annulaire dont la face extérieure est creuse pour conformer un canal à section en forme U dont l'ouverture est tournée vers l'extérieur et qui vient embrasser un élément annulaire de forme correspondante venu du corps de vanne, le fond de ce canal comporte deux rainures symétriques qui améliorent la souplesse et l'élasticité du siège; ce dernier est revêtu intérieurement d'une couche de difluorure de polyvinylidène qui constitue la couche de protection venant au contact du fluide. Application aux vannes papillons pour contrôler la circulation de fluides corrosifs tels que le chlore.
