Abstract
La vanne, du type général faisant l'objet du brevet principal, est établie selon l'addition pour véhiculer des liquides corrodant les métaux normalement utilisés. Le clapet 5, mobile autour d'un axe excentré 6 orthogonal à la conduite, coopère avec un siège constitué par le bord intérieur 23 d'une couronne 24 en matière plastique, telle que le polytétrafluoréthylène, dont le pourtour est encastré dans le corps de vanne 1 et qui se déforme par fluage pour coopérer avec une zone sphérique de portée 14 présentée par le clapet pivotant 5. L'ensemble des parties intérieures de la vanne est recouvert d'une matière plastique telle que le polytétrafluoréthylène.
