Electronic controller for soft water valve

Abstract

The invention discloses an electronic controller for a soft water valve. The controller comprises a system model setting unit, a regeneration setting unit, an exchange capacity setting unit, a remote signal control unit, a unit setting unit, a relay unit, a dosing pump unit and a flowmeter unit which are all connected with a processor, wherein the system model setting unit is used for setting the system model adopted by the soft water valve; the regeneration setting unit is used for setting the regeneration model and time of the soft water valve; the exchange capacity setting unit is used for setting the total exchange capacity and exchange capacity safety coefficient of the soft water valve; the remote signal control unit is used for achieving remote control of the electronic soft water valve controller; the unit setting unit is used for setting the unit incoming water hardness and the flow unit; the relay unit is used for achieving the water disconnection action under abnormal conditions; the dosing pump unit is used for controlling a dosing pump to carry out dosing; and the flowmeter unit is used for controlling a flowmeter to achieve flow computation.

Description

technical field [0001] The invention relates to an electronic controller, in particular to an electronic controller for controlling a soft water valve. Background technique [0002] In the water softening process, the water is softened by the resin, but the resin will fail after a long time, so the resin will be regenerated by adding salt water. At present, in the resin regeneration process, the start time of regeneration is controlled by mechanically controlling the soft water valve, which is usually divided into time control and flow control according to the timing mode. Time control can only control the number of days, and cannot adjust hours and minutes, and the number of days can only be a number divisible by the maximum number of days, (for example: the maximum number of days set is 12, and the number of days that can be set is: 12, 6, 4, 3 , 2, 1), flow control requires an additional flow meter to measure the flow, so the mechanical control valve has limitations in t...
