ACID DISPENSER FOR WATER SOFTENER UNIT

摘要

A dispenser for metering a predetermined volume of acid into a water softener brine tank utilizes a generally hat-shaped diaphragm that flops from one surface of a metering chamber to the opposite surface when acted upon by either pressure or suction. The diaphragm essentially lines one-half of the chamber at a time, and its movement either draws acid into the chamber or expels the acid from the chamber.
