    摘要: A rotary control valve (10) is provided for a liquid conditioning system. The rotary control valve includes a housing (12) 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 (14) 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.

    摘要: A seal mechanism (22) for a rotary control valve having a housing with a plurality of ports and a generally cylindrical rotor having an external surface and a plurality of ports rotatably located within the housing. The seal mechanism is located between the external surface of the rotor and the housing and includes a generally cylindrical collar (142) which extends substantially around the circumference of the rotor. The collar includes one or more ports adapted to respectively align with the ports in the rotor and in the housing and a groove extending around each collar port. A seal member (138) having an aperture, an outwardly extending first flange (184) and an inwardly extending second flange (192) is located within the groove of the collar. The first flange has a first sealing face adapted to sealingly engage the housing and the second flange includes a second sealing face adapted to sealingly engage the external surface of the rotor. The seal member is adapted to provide a sealed fluid passage through the aperture of the seal member between a port of the rotor and a port of the housing. A retainer member is associated with the seal member and includes an outer rim having an outer peripheral edge and an inner rim having an outer peripheral edge. The first flange of the seal member extends around the outer edge of the outer rim and the second flange of the seal member extends around the outer edge of the inner rim.
