The sealing component includes a first communication port opened on the surface of the first connecting ring near the electromagnetic flowmeter, and a second communication port opened on the surface of the second connecting ring near the electromagnetic flowmeter. A sealing ring is fixedly connected to the surface of the first connecting ring, and an installation ring is fixedly connected to the surface of the second connecting ring. An installation groove is opened inside the installation ring, and a sealing gasket is provided inside the installation ring.

A connecting assembly 3 is provided at the connection between the electromagnetic flowmeter 1 and the pipes 2. The connecting assembly 3 includes a first connecting ring 31 that is rotatably and sealingly connected to the surface of the pipe 2. A second connecting ring 32 is fixedly connected to both ends of the electromagnetic flowmeter 1.

A limiting plate 36 is provided inside the second connecting ring 32. A return spring 37 is fixedly connected to one side of the limiting plate 36. Two sets of connecting assemblies 3 are provided, and the two sets of connecting assemblies 3 are arranged opposite to each other at both ends of the electromagnetic flowmeter 1. The locking block 33 is fixedly connected to the first connecting ring 2. On the surface of the connecting ring 31, the locking blocks 33 are L-shaped. The number of locking blocks 33 and the locking slots 34 are the same, and the locking blocks 33 and the locking slots 34 are mutually compatible. The limiting plate 36 is slidably connected inside the limiting groove 35, and the limiting groove 35 limits the limiting plate 36. The return spring 37 is set inside the limiting groove 35, and the other end of the return spring 37 is fixedly connected to the inner wall surface of the limiting groove 35. When it is necessary to disassemble the electromagnetic flowmeter 1, simply press and rotate the first connecting ring 31 so that the locking blocks 33 on the surface of the first connecting ring 31 and the locking slots 34 are on the same horizontal line, and the electromagnetic flowmeter 1 can be removed. By setting the connecting component 3, the traditional flange connection is replaced, avoiding the need to tighten a large number of screws, so that the electromagnetic flowmeter 1 and the pipeline 2 can be quickly connected. At the same time, when it is necessary to disassemble the electromagnetic flowmeter 1, it can also be quickly disassembled.

[0024] Reference Figure 1 - Figure 3A sealing assembly 4 is provided inside the first connecting ring 31 and the second connecting ring 32. The sealing assembly 4 includes a first connecting port 41 on the surface of the first connecting ring 31 near the electromagnetic flowmeter 1, and a second connecting port 42 on the surface of the second connecting ring 32 near the electromagnetic flowmeter 1. A sealing ring 43 is fixedly connected to the surface of the first connecting ring 31, and an installation ring 44 is fixedly connected to the surface of the second connecting ring 32. An installation groove 45 is provided inside the installation ring 44, and a sealing gasket 46 is provided inside the installation ring 44.

During installation, the sealing ring 43 is inserted into the installation groove 45 and abuts against the surface of the sealing gasket 46 inside the installation groove 45, so that the connection between the electromagnetic flowmeter 1 and the pipe 2 is more stable and sealed under the pressure of the water pressure inside the pipe 2.

[0025] Working principle: In use, first rotate the first connecting ring 31 so that the locking block 33 on the surface of the first connecting ring 31 aligns with the locking groove 34. Insert the locking block 33 into the inside of the locking groove 34. The locking block 33 presses against the limiting plate 36 inside the limiting groove 35, compressing the return spring 37. Then continue to rotate the first connecting ring 31 so that the locking block 33 on the surface of the first connecting ring 31 is no longer on the same horizontal line as the locking groove 34. At this time, release the first connecting ring 31 so that the locking block 33 no longer presses against the limiting plate 36 inside the limiting groove 35. The return spring 37 drives the limiting plate 36 to return to its original position, thus firmly fixing the locking block 33 inside the limiting groove 35. When it is necessary to disassemble the electromagnetic flowmeter 1, simply press... By rotating the first connecting ring 31, the locking block 33 on the surface of the first connecting ring 31 and the locking groove 34 are aligned on the same horizontal line, and the electromagnetic flowmeter 1 can be removed. The connection component 3 replaces the traditional flange connection, avoiding the need to tighten a large number of screws, and enabling a quick connection between the electromagnetic flowmeter 1 and the pipeline 2. At the same time, when it is necessary to disassemble the electromagnetic flowmeter 1, it can also be disassembled quickly. During the installation process, the sealing ring 43 is inserted into the inside of the mounting groove 45 and abuts against the surface of the sealing gasket 46 inside the mounting groove 45, so that the connection between the electromagnetic flowmeter 1 and the pipeline 2 is more stable and sealed under the pressure of the water pressure inside the pipeline 2.
