Title
(EN) CHEMICALLY-RESISTANT FLUID CONTROL VALVES
(FR) VANNES REGULATRICES POUR FLUIDES, RESISTANTES AUX AGENTS CHIMIQUES
Abstract
(EN)
A chemically resistant fluid control valve is disclosed generally comprising fluid inlet (14) and outlet (16) passages separated by fluid control means, which control means comprises a flapper plate (20) disposed in the fluid passageway and mounted on a rotatable shaft (46) that passes laterally through the fluid passageway by means of releasable fasteners (60) adapted to engage correspondingly shaped fastener elements (23) of the flapper plate, which elements are also adapted to receive the shaft in a channel (24) between the fastener elements, wherein at least all wetted surfaces of each of the several components consist essentially of a chemically resistant material.
(FR)
L'invention concerne une vanne régulatrice pour fluides, résistante aux agents chimiques et comprenant essentiellement un passage d'entrée (14) et un passage de sortie (16) pour le fluide, séparés par un moyen de régulation du fluide, ce moyen comprenant un papillon (20) disposé dans le passage à fluide et monté sur un arbre rotatif (46), qui traverse latéralement le passage à fluide, par des dispositifs de fixation amovibles (60) conçus pour s'adapter à des éléments de fixation (23) de forme correspondante du papillon, lesquels éléments sont également conçus pour recevoir l'arbre dans un canal (24) entre les éléments de fixation. Au moins toutes les surfaces mouillées par le fluide de chacun des différents composants sont constituées essentiellement d'un matériau résistant aux produits chimiques.
