The working principle is that hard water contacts with a softening filter material in a resin tank in a certain flow direction through a flow channel structure, calcium ions, magnesium ions and the like in the hard water are replaced through exchange reaction, and water softening is achieved. The filter material begins to lose effectiveness gradually from the water inlet direction of the resin tank to the water outlet direction until the water outlet is larger than a failure standard value. After the softened filter material is invalid, the filter material needs to be regenerated and recovered, softened salt in a salt tank is dissolved into saturated salt water, and a prepared regeneration liquid is injected into a resin tank to re-exchange adsorbed calcium and magnesium ions and discharge the calcium and magnesium ions so as to regenerate the filter material.

Further, when applied to an overall softening system, the controller may also be used to coordinate the overall softening system with the operational, regeneration (salt absorption), backwash, forward wash, and refill stations.

In practical application, the regeneration station comprises a first working condition and a second working condition, and the specific working process is as follows:

the working condition I is as follows: as shown in fig. 4, after the softened filter material in the resin tank fails to operate, the control program controls the electric control plate to start the motor 4 to drive the movable valve plate 16 to rotate, at this time, the movable valve plate 16 is communicated with the first regeneration channel hole of the fixed valve plate 3 in series, and other stations and other regeneration channel holes are closed. Raw water enters a first regeneration flow channel in a valve body 5 of a control valve from a water inlet 6 of a soft water valve, the regeneration flow is a, then the raw water enters a mixer 15 from the valve body 5, and brine is sucked from a salt tank 12 by a siphon or pump pumping principle through a salt suction pipe 14 under the control of a salt valve 11 to be mixed into regeneration liquid with the concentration of A.

Working conditions are as follows: as shown in fig. 5, when the salt utilization rate begins to decrease in the regeneration process, the control program controls the electric control plate to start the motor 4 to drive the movable valve plate 16 to rotate, at this time, the movable valve plate 16 is communicated with the second regeneration flow channel hole of the fixed valve plate 3, and other stations and other regeneration hole channels are closed. Raw water enters a second regeneration flow channel in the valve body 5 of the control valve from the water inlet 6 of the soft water valve, the regeneration flow is B at the moment, then enters a mixer 15 from the valve body 5, and brine is sucked from a salt tank 12 by the siphon or pump pumping principle through a salt suction pipe 14 under the control of a salt valve 11 to be mixed into regeneration liquid with the concentration of B. The regenerated liquid enters a regeneration flow channel in the valve body 5 and then is input into the lower water distributor 10 from the valve body 5 through the central pipe 8. The lower water distributor 10 disperses the flow of the regenerated liquid and then uniformly contacts with the softened filter material 9 from bottom to top, the utilization rate of the regenerated liquid is improved by adjusting the environment of regenerated ions, and the regenerated waste water is collected by the upper water distributor 13, then is input into a flow passage in the valve body 5 and finally is discharged from a waste water port 2 of the softened valve.

When the utilization rate of the salt solution is reduced in the regeneration process, the concentration of the regeneration solution is reduced, the flow rate is increased (a is greater than B), and the concentration of hardness ions (A is less than B) is reduced; then the concentration of the regenerated liquid is improved, and the flow is reduced to improve the utilization rate of the regenerated liquid.
