A rotary control valve is provided for a liquid conditioning system. The rotary control valve includes a housing having a chamber formed about a central axis. The housing includes a plurality of ports aligned with one another along an axis generally parallel to the central axis. A rotor is located within the chamber and is selectively rotatable about the central axis. The rotor includes a central tubular wall extending along the central axis which includes a central fluid flow path. The rotor includes an inlet port adapted to provide fluid communication between the central fluid flow path and a source of untreated liquid. The rotor also includes a plurality of longitudinal sectors wherein each sector includes one or more radial chambers located in one or more tiers of the sector. One or more of the radial chambers in each sector includes an aperture to provide fluid communication between the central fluid flow path and the radial chamber. The radial chambers include respective peripheral apertures adapted to selectively place the radial chambers of a sector in fluid communication with one or more of the ports of the housing when the sector is rotated into alignment with the ports in the housing. Selective rotation of the rotor about the central axis to a selected rotational position opens and closes various fluid paths through the rotor and the housing.
Vanne de réglage rotative pour système de traitement de liquide. La vanne de réglage rotative est constituée d'une enveloppe entourant un compartiment formé autour d'un axe central. L'enveloppe comporte plusieurs points de sortie alignés les uns par rapport aux autres selon un axe généralement parallèle à l'axe central. Un rotor se trouve dans le compartiment et peut tourner de façon sélective autour de l'axe central. Le rotor comprend une paroi tubulaire centrale disposée le long de l'axe central et comportant une voie d'écoulement centrale. Le rotor comporte un orifice d'admission assurant l'écoulement du liquide entre la voie d'écoulement centrale et une source de liquide non traité. Le rotor comporte aussi plusieurs sections longitudinales, chaque section comprenant un ou plusieurs compartiments radiaux situés sur un ou plusieurs étages de la section. Un ou plusieurs compartiments radiaux de chaque section comportent un orifice assurant le flux du liquide entre la voie centrale d'écoulement et le compartiment radial. Chaque compartiment radial comporte un orifice périphérique adapté de manière à assurer l'écoulement du liquide d'une section vers un ou plusieurs des orifices de l'enveloppe lorsque la section est alignée avec les orifices de l'enveloppe. La rotation sélective du rotor selon un axe central vers une position de rotation sélectionnée permet d'ouvrir et de fermer diverses voies d'écoulement passant dans le rotor et l'enveloppe.
