CONTROL VALVE FOR A FLUID TREATMENT SYSTEM

摘要

Control Valve For a Fluid Treatment System A method and apparatus for controlling a fluid treatment apparatus that includes a resin tank containing an ion exchange media. A control valve controls the regeneration cycle and includes a regeneration control turbine operatively connected to a regeneration control disk forming part of a servo system. During regeneration, a meter flow of fluid emitted by a regeneration control nozzle produces rotation in the turbine to effect a regeneration sequence. Regeneration is initiated by a regeneration initiating nozzle which emits a stream of fluid at the turbine for a predetermined time interval in order to initiate a regeneration cycle. A control system includes a sensor for monitoring the fluid quality level of the source fluid or the treated fluid and communicates pressurized fluid to the regeneration initiating nozzle upon sensing a predetermined quality level.
