Detailed ways

Hereinafter, we will further describe the non-negative pressure stacked pressure water supply equipment described in the present utility model with reference to the accompanying drawings.

1-3, a non-negative pressure stacked water supply equipment in this embodiment includes a steady flow tank 1, a vacuum suppressor 11, a variable-frequency speed-regulating water pump 3, a buffer device 4, a pressure sensor 6 and a variable-frequency control cabinet 5; It is characterized in that a vacuum suppressor 11 is installed on the steady flow tank 1; the steady flow tank 1 is provided with a water inlet 12, a water outlet 18 and a cleaning valve 15; The high-pressure water spout 16 is provided with a sewage outlet 17 at the bottom; the water outlet 18 is connected with a water outlet pipe 13; the water outlet pipe 13 is connected with the variable frequency speed regulation water pump 3; The connecting pipe 9 is connected with a pressure sensor 6 and a buffer device 4; the variable frequency speed regulating water pump 3 and the pressure sensor 4 are both connected with the variable frequency control cabinet 5; A water pump inlet pipe 7 is connected between; a water pump outlet pipe 8 is connected between the frequency conversion speed regulation water pump 3 and the connecting pipe 9; a valve 2 is installed on the water pump inlet pipe 7 and the water pump outlet pipe 8; the frequency conversion speed regulation A support frame 10 is installed at the bottom of the water pump 3, the steady flow tank 1, the pressure sensor 6 and the connecting pipe 9; the support frame 10 is fixedly installed on the base 14; the buffer device 4 includes an upper casing 401, a lower casing 401 and the skin bag 403; the upper shell 401 and the lower shell 402 are provided with flanges 404; the upper shell 401 and the lower shell 402 are connected by the flange 404; the upper shell 401 and the lower shell A bladder 403 is installed between the bodies 402 ; the lower casing 402 is provided with a water inlet and outlet 405 and a support frame 10 .

In the working process of the utility model, the water inlet 12 of the steady flow tank 1 is directly connected with the municipal water supply, and the water of the municipal water supply directly enters the steady flow tank 1 through the water inlet 12. When the residential user needs water, the frequency conversion control cabinet 5 controls The variable frequency speed regulating water pump 3 starts to work, the water in the steady flow tank 1 flows from the water outlet 18 to the water outlet pipe 13, and the water outlet pipe 13 flows to the water pump inlet pipe 7 into the variable frequency speed regulating water pump 3, and then the water in the variable frequency speed regulating water pump 3 Then it enters the connecting pipe 9 through the water pump outlet pipe 8, and finally distributes it to each residential user. The pressure gauge 6 can send the data to the frequency conversion control cabinet 5 from time to time for easy observation. The equipment will automatically stop the water supply to protect the pipe network, and it will be controlled by the frequency conversion control cabinet 5 to control the number and frequency of the frequency conversion speed regulation water pumps 3, so as to achieve the effect of constant pressure water supply. The original pressure of the network is used for normal water supply, and the user water on the high floor will directly fall back to the device through the pipeline.
