Its structural features are: the flow buffer tank is provided with a partition to divide it into a water storage chamber and an energy storage chamber, and a pressure control valve connecting the water storage chamber and the energy storage chamber is arranged on the partition. The water pipe mouth is installed at the bottom of the water storage chamber. An energy storage water pipe is provided between the energy storage chamber and the user water pipe. An intelligent pressure regulator is installed on the energy storage water pipe. A remote pressure sensor is installed on the user water pipe.
