When the variable pressure value reaches the upper limit and runs stably, if the water supply pressure still does not reach the preset value, it is necessary to enter the pump increase process, gradually increasing from one first switch valve 19 to multiple, and vice versa. During this period, the water pressure of the fire water pipe can always be guaranteed, which is safer. The whole process realizes dual constant pressure control of fire fighting and domestic water use.

Then, the setting of the water reservoir 3 can be used to store tap water for backup purposes. When domestic water is used normally, the timer 15 can be used for timing, and then timing. When the specified time is reached, the controller 4 and the central processing unit 5 are used to control multiple first switch valves 19 to start in exchange, so as to avoid one first switch valve 19 always starting and reducing the service life.
