In practice, comparing the flow rates of two different pipelines requires setting up temporary platforms, and the data is often susceptible to interference. Furthermore, precise parameter control is often impossible to ensure accurate comparative testing of different pipeline flow paths under the same pressure conditions. Utility Model Content

[0003] In view of the above-mentioned problems, the purpose of this utility model is to provide a platform for pipeline flow comparison testing, which solves the technical problems of existing testing platforms being easily interfered with and unable to achieve accurate comparison testing.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A platform for pipeline flow comparison testing includes a central water supply control area and a first test area and a second test area located on either side of the central water supply control area. The first and second test areas are respectively connected to the central water supply control area. The water supply control area includes a central pipeline, which sequentially connects a buffer tank, a first circulating pump, and an electric pressure pump. At one end of the central pipeline, it splits into two branches, each branch equipped with a first ball valve and a second ball valve. Correspondingly, at the other end of the central pipeline, it splits into two branches, each branch equipped with a third ball valve and a fourth ball valve. The two ends of the first test area are respectively connected to the subsequent pipelines of the first and third ball valves, and the two ends of the second test area are respectively connected to the subsequent pipelines of the second and fourth ball valves. The first test area includes a first pipeline and a second pipeline arranged in parallel, with their ends connected. A flange connection port is provided on the first pipeline for connecting the pipeline to be tested via the flange.

[0023] like Figures 1-4 As shown, a platform for pipeline flow comparison testing includes a water supply control area in the middle and a first test area and a second test area on both sides of the water supply control area. The first test area and the second test area are respectively connected to the water supply control area in the middle. The water supply control area includes a central pipeline 7. The central pipeline 7 is connected in series with a buffer water tank 8, a first circulation pump 9 and an electric pressure pump 10. An air vent valve 16 is provided on the buffer water tank 8. At one end of the central pipeline 7, it splits into two branches, each branch being equipped with a first ball valve 1 and a second ball valve 2. Correspondingly, at the other end of the central pipeline 7, it splits into two branches, each branch being equipped with a third ball valve 3 and a fourth ball valve 4. The two ends of the first test area are connected to the subsequent pipelines of the first ball valve 1 and the third ball valve 3, respectively, and the two ends of the second test area are connected to the subsequent pipelines of the second ball valve 2 and the fourth ball valve 4, respectively. The first test area includes a first pipeline 11 and a second pipeline 12 arranged in parallel, with the ends of the first pipeline 11 and the second pipeline 12 connected to each other. A flange connection port is provided on the first pipeline 11 for connecting the pipeline to be tested through the flange. A fifth ball valve 5 and a second circulating pump 13 are provided on the second pipeline 12.

[0024] The first test area and the second test area have the same structural configuration. The second test area includes a third pipe 21 and a fourth pipe 22 arranged in parallel, with their ends connected. A flange connection port is provided on the third pipe 21 for connecting the pipe to be tested through the flange. A sixth ball valve 6 and a third circulation pump 14 are provided on the fourth pipe 22.

[0025] In this utility model, the first ball valve 1, the second ball valve 2, the third ball valve 3, and the fourth ball valve 4 are ball valves of the same specification, the fifth ball valve 5 and the sixth ball valve 6 are ball valves of the same specification, and the second circulating pump 13 and the third circulating pump 14 are circulating pumps of the same specification.

[0026] The pipeline to be tested is connected to the first pipeline 11 or the third pipeline 21 via a flange. A flow meter 15 is installed on the pipeline to be tested to observe the flow rate of the pipeline.

[0027] The first pipeline 11 in the first test area is connected to the first pipeline to be tested via a flange, and the third pipeline 21 in the second test area is connected to the second pipeline to be tested via a flange.

[0028] This utility model's water supply control area includes a buffer tank 8, a first circulation pump 9 (large pump), and an electric pressure pump 10. An air vent valve 16 is also located above the buffer tank 8. The connection to the first and second test areas can be shut off via four ball valves: first ball valve 1, second ball valve 2, third ball valve 3, and fourth ball valve 4. See details... Figure 2 .

[0029] This utility model has two test areas: a first test area and a second test area with identical structural configurations, used to test the first and second pipes to be tested. The pipes to be tested are connected using flanges, with the pipes cut in the middle, and flow meters are installed (flow meter 1 in the first test area and flow meter 2 in the second test area). Each area is also equipped with a circulating pump (small pump), of the same model: second circulating pump 13 and third circulating pump 14. Next to each circulating pump is a ball valve for shut-off, namely ball valve 5 (fifth ball valve) and ball valve 6 (sixth ball valve), as detailed below. Figure 3 and Figure 4 .

[0030] The platform for pipeline flow comparison testing of this utility model is operated as follows:

[0031] First, install and vent the pipe to be tested: Divide the pipe into two equal sections, install a flow meter 15 in the middle, and connect them to the system via flanges. Open all ball valves, fill the buffer tank 8 with water, and turn on the first circulation pump 9 to fill the system pipeline with water. Vent the air in the pipeline through the vent valve 16 on the buffer tank 8. Continue until the first circulation pump 9 stops making bubbling noises and the vent valve 16 stops making gas ejection noises. Then, turn off the first circulation pump 9 and close the vent valve 16.

[0032] Independent Flow Rate Comparison Test: Keep all water pumps off and all ball valves open. First, turn on the electric pressure pump 10 to pressurize the entire pipeline to the set value (the pressure will drop due to air between water molecules, requiring multiple pressurizations). After the water pressure stabilizes, turn off the electric pressure pump 10 and close ball valves 1, 2, 3, and 4. Turn on the second circulation pump 13 and the third circulation pump 14 (at the same speed). This puts the two pipelines under test in an independent flow rate comparison test. Flow meters 1 and 2 can be observed to compare the flow rates of the two pipelines. See details... Figure 5 The arrows in the diagram indicate the direction of water flow.

[0033] Parallel Flow Rate Comparison Test: Keep all water pumps off and all ball valves open. First, turn on the electric pressure pump 10 to pressurize the entire pipeline to the set value (the pressure will drop due to air between water molecules, requiring multiple pressurizations). After the water pressure stabilizes, turn off the electric pressure pump 10. Close ball valves 5 and 6. Turn on the first circulation pump 9. This puts the two pipelines under test in parallel flow rate comparison. Flow meters 1 and 2 can be observed to compare the flow rates of the two pipelines. See details... Figure 6 The arrows in the diagram indicate the direction of water flow.

[0034] It should be noted that all connecting pipes in this embodiment are pipes of the same specification.
