DISTRIBUTOR ARRANGEMENT FOR A FLUID TREASTMENT TANK

摘要

A distributor plate for a resin tank of a fluid treatment device such as a water softener includes a central hub, an outer ring, a plurality of ribs extending between the hub and the ring and dividing the distributor plate into discrete segments, and a slotted plate connected therebetween. The distributor plate separates the resin bed from a lower end of the resin tank. The distributor plate further comprises at least one valve plate coupled to an underside of the distributor plate over at least one segment thereof. The valve plate is constructed from a material configured to float in the fluid being treated and is movable between a raised position during upflow and a lowered position during downflow. In this manner, the valve plate acts like a check valve to regulate the manner in which fluid flows through the distributor plate during upflow and downflow, improving resin scrubbing during upflow.

主权项

1. A treatment tank for a fluid treatment system, comprising:
a tank containing a bed of a fluid treatment media and a fluid; a distributor plate received in the tank and separating the bed from a lower end of the tank, and at least one valve plate covering a portion of and coupled to an underside of the distributor plate and configured to be selectively movable between a lowered position during a downflow operation and a raised position during an upflow operation, thereby permitting relatively unrestricted fluid flow therepast during downflow operation and at least substantially preventing fluid flow therepast during upflow operation.
