Technical Field

[0001] The utility model relates to the technical field of electromagnetic flowmeters, and more specifically, to an assembled electromagnetic flowmeter. Background Art

[0002] With the rapid development of social economy, electromagnetic flowmeter is a new type of flow measurement instrument that has developed rapidly in the 1950s and 1960s with the development of electronic technology. Electromagnetic flowmeter is an instrument that uses the principle of electromagnetic induction to measure the flow rate of conductive fluid based on the induced electromotive force when the conductive fluid passes through an external magnetic field. Electromagnetic flowmeter is a flowmeter that measures flow based on Faraday's law of electromagnetic induction. The advantages of electromagnetic flowmeter are extremely small pressure loss, large measurable flow range, and the ratio of maximum flow to minimum flow is generally more than twenty to one. It is applicable to a wide range of industrial pipe diameters, up to three meters. The output signal is linear with the measured flow and has high accuracy.

[0003] However, during the installation process, existing electromagnetic flowmeters are usually installed and fixed using bolts and nuts or flanges. When the electromagnetic flowmeter needs to be regularly inspected or replaced, it needs to be disassembled. During the disassembly and assembly process, it is generally necessary to use external tools to remove the bolts one by one, resulting in slow installation and disassembly, affecting work efficiency.

[0023] The two limiting plates 11 both pass through the mounting box 6 and are slidably connected to the mounting box 6. The positions of the two measuring tubes 2 corresponding to the mounting box 6 are provided with second limiting grooves 16, and the second limiting grooves 16 are used to limit the limiting plates 11; the outer upper positions of the two adjusting plates 14 are fixed with first L-shaped adjusting blocks 7, and the outer ends of the first L-shaped adjusting blocks 7 both pass through the mounting box 6 and are slidably connected to the mounting box 6; a plurality of first limiting grooves 15 are provided inside the conveying pipe 1, and the first limiting grooves 15 are used to limit the limiting plates 11. By The node block 7 is pressed in the opposite direction and cooperates with the mobile installation box 6, so that when the limit plate 11 and the second limit groove 16 are overlapped after the first L-shaped adjustment block 7 is loosened, the delivery pipe 1 and the measuring tube 2 can be quickly connected. When the mobile installation box 6 drives the limit plate 11 to move and loosens the first L-shaped adjustment block 7, the limit plate 11 and the first limit groove 15 are overlapped, the delivery pipe 1 and the measuring tube 2 can be separated conveniently, so that the electromagnetic flowmeter body 5 does not need to be disassembled and installed when it needs to be repaired, and the installation efficiency is improved.

[0024] The two first L-shaped adjustment blocks 7 are fixedly connected to the second L-shaped adjustment blocks 8 at the opposite ends, and the bottom ends of the two second L-shaped adjustment blocks 8 are fixedly connected to the limit blocks 9; two slide grooves 10 are respectively provided at the positions corresponding to the limit blocks 9 on the top of the installation box 6, and the two limit blocks 9 are slidably arranged inside the slide grooves 10.

[0025] It should be noted that, by pressing the first L-shaped adjustment block 7, the second L-shaped adjustment block 8 can drive the limit block 9 to slide inside the slide groove 10, so that when the first L-shaped adjustment block 7 is pressed, the limit plate 11 can be driven to move synchronously, and the first L-shaped adjustment block 7 and the limit plate 11 are connected to the adjustment plate 14, so that when the first L-shaped adjustment block 7 is pressed, the two ends of the adjustment plate 14 are balanced, which can improve the stability of the limit plate 11 when it moves and limits the second limit groove 16.

[0026] A telescopic rod 12 is arranged between the first L-shaped adjusting block 7 and the mounting box 6, one end of the telescopic rod 12 is connected to the first L-shaped adjusting block 7, and the other end of the telescopic rod 12 is connected to the surface of the mounting box 6, so that the telescopic rod 12 can be automatically shortened when the first L-shaped adjusting block 7 is pressed, and when the first L-shaped adjusting block 7 is released, the telescopic rod 12 can automatically push the first L-shaped adjusting block 7 to move outward by its own elasticity, so that the first L-shaped adjusting block 7 can be automatically reset when not pressed, and at the same time, the limit plate 11 can be driven by the telescopic rod 12 to automatically overlap with the second limit groove 16 or the first limit groove 15.

[0028] In this embodiment, the implementation scenario is specifically as follows: when the device is being repaired, the first L-shaped adjustment block 7 on the surface of one of the installation boxes 6 is first pressed and pressed in the opposite direction. At the same time, the first L-shaped adjustment block 7 can drive the adjustment plate 14 to squeeze the spring 13, so that the two adjustment plates 14 are close to each other, and the limiting plate 11 can be driven to move and approach each other, and can be conveniently driven to move and be stored in the installation box 6. At this time, the limiting plate 11 is separated from the second limiting groove 16. At the same time, by pulling the installation box 6 upward, when the limiting groove 16 is pulled upward, the limiting groove 16 is pulled upward. When the height level of the plate 11 is higher than the second limiting groove 16, the first L-shaped adjusting block 7 is released. At this time, the adjusting plate 14 can be pushed outward by the elastic extension of the spring 13 itself, so that when the installation box 6 drives the limiting plate 11 to move through the first limiting groove 15, the limiting plate 11 can push the adjusting plate 14 through the spring 13 to automatically overlap with the first limiting groove 15. Repeating this operation in sequence can separate the remaining limiting plates 11 from the first limiting groove 15 in sequence, making it convenient to separate and disassemble the conveying pipe 1 and the measuring pipe 2, and realizing the function of convenient maintenance without the help of tools;

[0029] After the inspection is completed, first insert the measuring tube 2 into the conveying tube 1, and then press the first L-shaped adjustment block 7 in the opposite direction in turn to drive the limit plate 11 to move and separate from the first limit groove 15 to the second limit groove 16 and release it. Use the second limit groove 16 to limit the limit plate 11, so that the conveying tube 1 and the measuring tube 2 can be quickly connected, and the function of convenient and quick installation of the electromagnetic flowmeter body 5 can be realized.
