Detailed ways

As shown in the accompanying drawings, an emergency water tank 7 is arranged in parallel on the pipeline between the tap water pipe network 1 and the water pump group 9, and the tap water pipe network 1 is divided into two branches before the emergency water tank 7, namely the tap water supply pipeline and the water supply tank pipeline, the water supply pipeline of the water tank is connected with the inlet end of the emergency water tank 7, the outlet end of the emergency water tank 7 is connected with the water pump unit 9 through the water outlet pipeline of the water tank, and the tap water supply pipeline is connected with the water pump unit 9, and the inlet of the emergency water tank 7 1. Water tank water inlet solenoid valve 4, water tank water outlet solenoid valve 8, and ball float valve 16 are respectively set at the outlet end, and tap water water inlet solenoid valve 5 is set on the tap water supply pipeline. In order to prevent the backflow of tap water and affect the normal operation of the tap water pipe network, a backflow preventer 3, a tap water pipe network pressure sensor 2, a water flow indicator 15, a negative pressure compensation device 6, and a water pump group 9 are installed on the tap water pipe network. The pipeline between the pipe networks 14 is provided with a user pipe network pressure sensor 13, and the upper and lower ends of the emergency water tank 7 are respectively provided with an upper liquid level sensor 11 and a lower liquid level sensor 12.
