Abstract

La présente invention concerne un appareil destiné à réguler l'écoulement d'un liquide chimique, et qui comprend : un logement comportant une chambre à vanne ; un élément rotatif logé de manière rotative dans la chambre à vanne ; une pluralité de lignes de transfert de liquide chimique qui pénètrent dans la chambre à vanne, s'enroulent autour de la circonférence extérieure de l'élément rotatif à des hauteurs différentes, et sont conduites hors de la chambre à vanne ; un dispositif de combinaison de liquide chimique, destiné à combiner les liquides chimiques s'écoulant hors de la pluralité de lignes de transfert de liquide chimique en un écoulement unique ; et un moyen d'ouverture/fermeture de lignes de transfert destiné à obstruer ou libérer de manière sélective les lignes de transfert de liquide chimique dans la chambre à vanne, de sorte que l'ensemble des lignes parmi la pluralité de lignes de transfert de liquides chimiques soit ouvert ou fermé ou qu'une partie des lignes de transfert de liquides chimiques soit fermée en fonction de l'angle de rotation de l'élément rotatif.
