[0002] At present, some boiler softening water treatment devices use multifunctional flat integrated valve integrated control. The following problems exist in the use of this equipment:

[0003] 1. The multifunctional flat integrated valve has design defects and poses a safety hazard. The sealing of each channel inside the valve body is completed by the sealing ring, which is prone to the cross-channel of hard water and softened water, resulting in unstable water hardness index. The soft water hardness is between 0.02 and 0.03 mmol / L, which is close to the lower limit of the index. The risk of boiler scaling is increased, causing the boiler system to be in an unsafe operating state.

[0004] 2. Waste of water resources. If the seal of the ion exchanger fails and continues to operate, the hardness in the soft water tank will exceed the standard. At this time, it is necessary to drain nearly 200 tons of water in the soft water tank, and then activate another normal ion exchanger to replenish the soft water tank, resulting in a waste of water resources.

[0036] The process flow of the fully automatic softening water treatment device: backwash, salt absorption, slow wash, normal wash, standby, and water production.

[0037] Backwash: The third electric valve 300 and the second electric valve 200 are opened, and the other electric valves are closed. Raw water enters from the pipeline of the soft water tank 1 and is discharged to the drain pipe 2 through the upper pipeline 11. When the accumulated backwash time of the control unit reaches the preset value, it automatically jumps to the salt absorption process.

[0038] Salt absorption: The sixth electric valve 600 and the second electric valve 200 are opened, and the other electric valves are closed. Salt water enters from the lower pipe 12 of the soft water tank 1 and is discharged to the drain pipe 2 through the upper pipe 11. The control unit accumulates salt absorption time to a preset value and automatically jumps to the slow washing process.

[0039] Slow wash: The sixth electric valve 600 and the second electric valve 200 are opened, and the other electric valves are closed. When the accumulated slow wash time of the control unit reaches the preset value, it automatically jumps to the normal wash process.

[0040] Normal wash: the first electric valve 100 and the fourth electric valve 400 are opened, and the other electric valves are closed. When the accumulated normal wash time of the control unit reaches the preset value, it automatically jumps to the standby process.

[0041] Standby: All electric valves are closed, the control unit displays the regeneration completion mark, and waits for the water production command.

[0042] Water production: the first electric valve 100 and the fifth electric valve 500 are opened, and the other electric valves are closed. When the accumulated water production time of the control unit reaches the preset value (or the hardness of the produced water reaches the preset value), it automatically jumps to the backwash process and then repeats the cycle; the hardness detector 6 detects the quality of the produced water. When the hardness of the softened water exceeds the target value, the fifth electric valve 500 is closed and the fourth electric valve is opened. The unqualified softened water is discharged from the drain pipe 2, and the cleaning process jumps to backwash.
