The water inlet pipe 1 is connected with a first flow controller 31 through a main flow pipeline 3, a first electromagnetic valve 32 is arranged on the main flow pipeline 3, and the first flow controller 31 is connected with the water outlet pipe 9 through a first water outlet unit 81. The input end of the double-cavity type steady flow compensation tank 5 is connected with the water supplementing pipeline 4, the output end of the double-cavity type steady flow compensation tank 5 is provided with a first compensation pipeline 6 and a second compensation pipeline 7, and the water supplementing pipeline 4 is provided with a first check valve 41. The output end of the first compensation pipeline 6 is connected with the main flow pipeline 3, and the first compensation pipeline 6 is sequentially provided with a second electromagnetic valve 61 and a second check valve 62 from the input end; the output end of the second compensation pipeline 7 is connected with a second flow controller 73, the second flow controller 73 is connected with the water outlet pipe 9 through a second water outlet unit 82, and the second compensation pipeline 7 is sequentially provided with a third electromagnetic valve 71 and a booster compensation pump 72 from the input end. Wherein, the input end of the water supplementing pipeline 4 and the output end of the first compensating pipeline 6 are respectively positioned at two sides of the first electromagnetic valve 32 on the main pipeline 3.
Further, in this embodiment, the dual-cavity type flow stabilization compensation tank 5 is provided with an intelligent digital display device 51 and a second pressure sensor 52, and the first electromagnetic valve 32, the second electromagnetic valve 61, the third electromagnetic valve 71, the boost compensation pump 72, the first flow controller 31, the second flow controller 73, the first pressure sensor 2, the second pressure sensor 52 and the intelligent digital display device 51 are all connected with the control cabinet.
Further, in the present embodiment, the first water outlet unit 81 and the second water outlet unit 82 are respectively provided with a wafer check valve 83, a water outlet soft joint 84 and a wafer butterfly valve 85 in sequence from the input end, and the water outlet pipe 9 is connected with a user pipe network.
The specific operation is as follows:
the first pressure sensor 2 detects the water pressure in the water inlet pipe 1 and is divided into three degrees of low pressure, medium pressure and high pressure from small to large.
When the first pressure sensor 2 detects that the water pressure is in a high-pressure range, the first electromagnetic valve 32 is opened, the second electromagnetic valve 61 and the third electromagnetic valve 71 are closed, water flows from the main flow pipeline 3 to the first flow controller 31, and flows into the water outlet pipe 9 through the first water outlet unit 81 after being regulated and controlled by the first flow controller 31. Meanwhile, water in the main flow pipeline 3 enters the dual-cavity type steady flow compensation tank 5 from the divided water replenishing pipeline 4 through the first check valve 41, and under the condition that the dual-cavity type steady flow compensation tank 5 has a vacant volume, the first check valve 41 is opened by the water pressure in the main flow pipeline 3, so that the water in the main flow pipeline 3 flows into the dual-cavity type steady flow compensation tank 5 through the water replenishing pipeline 4. When the double-cavity type steady flow compensation tank 5 is completely filled with water or the water pressure in the main flow pipeline 3 is insufficient, the first check valve 41 automatically enters a closed state, so that the water supply pressure of the municipal pipe network is ensured.
When the first pressure sensor 2 detects that the water pressure is in the medium-pressure range, the first electromagnetic valve 32 and the second electromagnetic valve 61 are opened, the third electromagnetic valve 71 is closed, and the second check valve 62 is opened by the water pressure in the double-cavity type steady-flow compensation tank 5, so that the water in the double-cavity type steady-flow compensation tank 5 flows into the main flow pipeline 3 through the first compensation pipeline 6, differential pressure compensation is performed on the water supply of the municipal pipe network, and the normal water supply of the municipal pipe network is ensured. The collected water enters the water outlet pipe 9 through the first water outlet unit 81 after the flow rate of the collected water is regulated and controlled by the first flow controller 31. When the water pressure in the double-cavity type steady flow compensation tank 5 is smaller than the water pressure in the main flow pipeline 3, the second check valve 62 automatically enters a closed state, so that the water supply pressure of the municipal pipe network is ensured.
When the first pressure sensor 2 detects that the water pressure is in a low-pressure range, the first electromagnetic valve 32 and the second electromagnetic valve 61 are closed, the third electromagnetic valve 71 is opened, the control cabinet controls the pressurizing compensation pump 72 to operate, the pressurizing compensation pump 72 pumps water from the double-cavity type steady-flow compensation tank 5, pressurizes the pumped water and inputs the pressurized water into the second flow controller 73 through the second compensation pipeline 7, and the pumped water enters the water outlet pipe 9 through the second water outlet unit 82 after the flow is regulated and controlled by the second flow controller 73, so that the water supply stop condition caused by the fact that the municipal pipe network cannot supply water is avoided. The rotation speed of the pressure boosting compensation pump 72 is controlled by the variable frequency control cabinet. Meanwhile, when the second pressure sensor 52 detects that the water pressure in the dual-cavity type flow-stabilizing compensation tank 5 is lower than the warning value and the water pressure of the municipal pipe network is insufficient, the dual-cavity type flow-stabilizing compensation tank 5 continuously utilizes the water replenishing pipeline 4 to inject water into the dual-cavity type flow-stabilizing compensation tank 5 through the pressure boosting compensation pump 72 until the dual-cavity type flow-stabilizing compensation tank 5 enters a low liquid level protection state.
In summary, in this embodiment, the pressure-increasing and flow-stabilizing water supply equipment without the negative pressure pipe network provided performs switching between compensation water supply and standby water supply through the two compensation pipelines output by the dual-cavity flow-stabilizing compensation tank according to different states of the water pressure in the water inlet pipe, so as to ensure that the user can always receive the water for use from the user pipe network.
