Detailed Description

The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.

Example (b): a multifunctional water supply device is shown in figure 1 and comprises a water supply pipe 1 and a water tank 2, wherein a water supply valve 3 is arranged on the water supply pipe 1, a water outlet of the water supply pipe 1 is connected with a water inlet of the water tank 2, a first liquid level sensor 4 is arranged in the water tank 2, the water tank 2 is connected with a plurality of groups of water supply pipelines, each water supply pipeline comprises a connecting pipe 5, a water pump 6, a water outlet pipe 7 and a water supply pipe network 8 which are sequentially connected, a water outlet of the water tank 2 is connected with a water inlet of the connecting pipe 5, the outlet end of the water outlet pipe 7 is provided with a water pressure sensor 9, a flow sensor 10 and a waterproof hammer air valve 11, the outlet of the water outlet pipe 7 is also connected with a pressure stabilizing device 13 through a water pipe 12, a pressure fluctuation pre-stopping valve 14 is arranged at, the control cabinet is also electrically connected with the water supply valve 3, the first liquid level sensor 4, the water pressure sensor 9, the flow sensor 10, the water hammer prevention air valve 11 and the pressure fluctuation prevention valve 14.

The water supply pipeline is at least provided with two groups, and different groups supply water for different floors.

The pressure stabilizing device 13 comprises a pressure stabilizing tank 131, an electromagnetic on-off valve 132 and an air pump 133, the pressure stabilizing tank 131 is connected with the water outlet pipe 7 through a water pipe 12, the electromagnetic on-off valve 132 is arranged on the water pipe 12, an air outlet of the air pump 133 is communicated with the top of an inner cavity of the pressure stabilizing tank 131, and the electromagnetic on-off valve 132, the air pump 133 and the control cabinet are electrically connected.
