The full-automatic water softening device 8 starts to work, and the resin tank and salt tank soften the tap water. The softened water enters the water replenishing tank 7 through the water replenishing system 6. Then, the water pump in the circulation system 5 starts, and conveys the water in the water replenishing tank 7 to the plate heat exchanger 4 through the pipeline. At this time, the check valve in the system ensures the correct water flow direction and prevents water from flowing back. The softened water enters the plate heat exchanger 4 and exchanges heat with the hot water in the primary water supply pipe 11, absorbing heat. During the operation of the system, according to the instructions of the PLC control cabinet 1, the electric temperature control valve group 3 adjusts the flow rate between the primary water supply pipe 11 and the primary water return pipe 14 to control the heat exchange efficiency. After the hot water in the primary water supply pipe 11 passes through the plate heat exchanger 4, the temperature decreases and returns to the primary water return pipe 14 through the circulation system 5. At the same time, the ball valve, thermometer and Y-type filter in the circulation system 5 ensure smooth water flow and filter impurities. And when the system detects a decrease in water pressure or a reduction in water flow, the water replenishing system 6 automatically starts to replenish the water in the plate heat exchanger 4 and the circulation system 5. When the system needs to stop, the PLC control cabinet 1 will gradually turn off each component to ensure the safe and stable shutdown of the system.
