Description

Technical Field

[0001] The utility model relates to the technical field of balanced flowmeters, in particular to a balanced flowmeter with high precision. Background Art

[0002] A balanced flowmeter is a flow measurement instrument that works based on the differential pressure principle. It has multiple apertures, can effectively achieve a state of fluid balance, and maximizes the use of the principle of the differential pressure flowmeter. This flowmeter has a unique design and can not only measure liquids, but also has very good measurement advantages for gases, steam, and gas-liquid two-phase mixed gases. Balanced flowmeters have high linearity, good repeatability, and are resistant to high temperatures and high pressures. They are widely used in steam, gas, and high-pressure applications. However, when the viscosity of the fluid changes, the data detected will be different when the fluid passes through the flowmeter. Therefore, a high-precision balanced flowmeter is required.

[0003] The application number retrieved is: CN201610753617.X, a high-precision balanced flowmeter, which greatly improves the practicality of the connecting pipe in the measurement process of different types of sensors and facilitates the staff to quickly install and disassemble.

[0004] However, the existing balanced flowmeters still have certain defects in actual use: when detecting the fluid, when the viscosity of the fluid changes, the throttling of the fluid will be changed. When the viscosity of the fluid passes through the speed regulating ring, it will cause its pressure difference to change, thereby causing changes in the detection of the fluid. For this reason, we propose a balanced flowmeter with high precision. Utility Model Content

[0005] In order to make up for the above deficiencies, the utility model provides a high-precision balanced flowmeter, which aims to improve the problem that when the viscosity of the fluid changes during fluid detection, the throttling of the fluid is changed. When the viscosity of the fluid passes through the speed regulating ring, the pressure difference will change, thereby causing changes in the detection of the fluid.

DETAILED DESCRIPTION

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] like Figure 1-Figure 4As shown, a balanced flow meter with high precision includes a main pipe 1 and a speed regulating assembly 17, a first flow pipe 11 is arranged on the side of the main pipe 1, a connecting bracket 2 is installed on the top of the main pipe 1 by bolts, a first pressure-taking pipe 3 is installed on the top of the connecting bracket 2, a second pressure-taking pipe 4 is arranged on the side of the first pressure-taking pipe 3 away from the first flow pipe 11, a detection module 7 is arranged on the side of the main pipe 1 away from the first pressure-taking pipe 3, the speed regulating assembly 17 is arranged on the side of the main pipe 1 away from the detection module 7, and a second flow pipe 16 is arranged on the side of the main pipe 1 away from the first flow pipe 11, wherein the hydraulic pressure inside the pipeline is detected, and at this time, due to the different viscosities of different fluids, the accuracy of the detection will be affected, and at this time, by replacing the speed regulating ring 13 inside the speed regulating assembly 17, it is convenient to adjust the viscosity of the fluid.

[0023] The speed regulating assembly 17 includes a speed regulating ring 13, a mounting bracket 1701, a buckle 18, a connecting column 19 and a docking bracket 20, and the docking bracket 20 is installed on the left side of the speed regulating ring 13 by bolts, and a connecting column 19 is provided on the side of the docking bracket 20 away from the speed regulating ring 13, and a mounting bracket 1701 is provided on the side of the connecting column 19 away from the docking bracket 20, and a buckle 18 is provided on the side of the mounting bracket 1701 away from the connecting column 19. At this time, the connection between the speed regulating assembly 17 and the main pipe body 1 is released by pressing the buckle 18, and the speed regulating assembly 17 is pulled out, thereby pulling out the speed regulating ring 13. At this time, by separating the docking bracket 20 and the speed regulating ring 13, a different speed regulating ring 13 has been replaced, so that the size of the flow hole 21 of the speed regulating ring 13 can be adjusted according to the flow viscosity of the flow inside the main pipe body 1, thereby facilitating the adjustment of the flow of the flow ring to the fluid.

[0024] Circulation holes 21 are provided on both sides of the speed regulating ring 13, and the sizes of the circulation holes 21 are the same, and the distances between the circulation holes 21 are the same. At this time, the sizes of the speed regulating rings 13 are the same, and by replacing the speed regulating rings 13, the circulation holes 21 of the speed regulating rings 13 are adjusted to adapt to the circulation of the fluid.

[0025] A first sensor probe 14 is provided below the first pressure taking tube 3, and a second sensor probe 15 is provided below the second pressure taking tube 4. At this time, the first sensor probe 14 and the second sensor probe 15 are respectively located on both sides of the speed regulating ring 13 to detect the flow velocity of the fluid passing through the speed regulating ring 13 on both sides.

[0026] The first circulation pipe 11 and the second circulation pipe 16 are both installed with a docking ring 12 on the side away from the main pipe body 1 through bolts, and the first circulation pipe 11 and the second circulation pipe 16 are both provided with a connecting pipe 5 on the side away from the speed regulating component 17. At this time, the first circulation ring and the second circulation ring are installed on other pipelines through the docking ring 12.

[0027] Mounting rings 10 are installed on both sides of the main body 1 by bolts, and the two sets of mounting rings 10 are the same size. The connection points between the main body 1 and the first flow tube 11 and the second flow tube 16 are sealed by the mounting rings 10, thereby completing the support of the nodes between the main body 1 and the first flow tube 11 and the second flow tube 16.

[0029] In summary, the utility model is through the main body 1 and the speed regulating component 17, wherein when the fluid is detected inside the main body 1, the speed regulating component 17 is installed with the speed regulating ring 13 through the connecting column 19 and the docking bracket 20, and the speed regulating component 17 is inserted into the main body 1, and the speed regulating component 17 and the main body 1 are fixed by the buckle 18. At this time, the fluid flows along the first flow pipe 11, and the fluid impacts the speed regulating ring 13 inside the main body 1. At this time, the fluid circulates through the debugging holes in the speed regulating ring 13. When the fluid passes through these holes, they will be balanced and rectified, and the eddy current will be minimized, thereby forming a near-rational flow. The data of the first sensor probe 14 and the second sensor probe 15 are transported through the first pressure taking tube 3 and the second pressure taking tube 4 into the pressure film box 8 inside the detection module 7 to detect the flow data. At this time, when the viscosity of the fluid changes, the speed regulating ring 13 in the speed regulating assembly 17 is replaced to adjust the size of the flow hole 21 of the speed regulating ring 13 according to different fluid viscosities.
