Water softener valve

Abstract

A water softener valve for controlling water flow to and from a water softener is disclosed that includes a cylindrical shaft extending from said inner surface of a piston chamber that fits into a pressure relief port when the piston is in the service position. The shaft clears the pressure relief port of any debris and closes the pressure relief port during the service cycle. The water softener valve also has a flow meter with at least two helically expanding vanes. A magnet on of the vanes trips a sensor as the turbine rotates, thereby providing means for calculating the flow of water through the valve. The valve also has a flow control button located at an inlet of the valve rather than at the drain, preventing the obstruction of the water flow by regeneration sediment of the tank at the drain. The valve also contains an internal piston port for permitting the free flow of water through the valve during a change in softener cycles.

Description

【Technical field】 [0001] The present invention relates to a method and device for controlling the water flow in and out of a water softener, more particularly, the invention relates to a valve capable of controlling the flow of water in and out of a water softener and measuring the water flow at the same time. 【Background technique】 [0002] Home water softeners utilizing ion exchange resins typically include an ion exchange resin storage tank through which hard water flows to exchange its calcium and magnesium hard ions for the sodium soft ions of the ion exchange resin bed. Ion exchange resin beds need to be periodically regenerated to remove hard ions and replenish soft ions. Regeneration can be performed by flushing the storage tank with a brine solution, that is, using a brine solution to replenish the ion exchange resin bed with sodium ions. [0003] Water softeners typically require valves to control the flow of water into and out of the softened water tank during wo...
