The flow controller 5 of this embodiment can adopt a commonly used element or device in the field with a function of controlling pipeline flow, such as an electronic flow valve.

Please refer to Figure 1 again, the voltage stabilization control system also includes a water storage device 1, which is also connected to the water supply pipeline and the return pipeline. The entire water storage device 1 can adopt a commonly used water storage device in the art, such as a water storage tank.

Please refer to FIG. 1 again, the water bag 6 is also provided with a pressure stabilizing device 9 that blocks the flow of liquid and allows air to pass through, and a pressure collecting mechanism 8 that collects the internal pressure of the water bag 6.

The pressure stabilizing device 9 is a water blocking filter; the pressure collecting mechanism 8 is a pressure sensor.

The pressure collection mechanism 8 is also connected to a control device through feedback, and the control device is also connected to the second power device 3 through a frequency converter. In the drainage mode, the control device receives the pressure signal fed back by the pressure collection mechanism 8, and controls the flow of the second power device 3 through the frequency converter, thereby ensuring that the pressure in the water bag 6 is in a dynamic equilibrium state.

In specific operation, the voltage stabilization control system of this embodiment can have the following multiple working modes through pipeline switching, and the dotted lines in the following figures indicate that the pipeline is disconnected at this point:

In the water injection and circulation mode, as shown in FIG2 , the pipeline switching module 710 is used to adjust the pipeline on-off condition, so that the water storage device 1 forms a cycle through the water supply pipeline, the return pipeline and the water bag 6. The pure water in the water storage device 1 is sucked into the water bag 6 by the first power device 2 through the water supply pipeline, and the air in the water bag 6 is brought into the water storage device 1 by the second power device 3 through the return pipeline.

At this time, the flow controller 5 can be closed to avoid pipeline pressure imbalance. During this process, negative pressure is generated in the water bag 6, and the outside air enters the water bag 6 through the pressure stabilizing device 9. When the pressure in the water bag 6 is lower than the lower limit value, the control device receives the pressure signal of the water bag 6 fed back by the pressure collection mechanism 8, and reduces the flow of the second power device 3 through the inverter, so that the pressure in the water bag 6 is in a dynamic equilibrium state.
