When the liner is in contact with the flowing liquid for a long time, it will wear down and age, requiring replacement. However, existing electromagnetic flow meters usually adopt an integrated design, reducing the number of detachable parts. This makes the installation and removal of the electromagnetic flow meter liner very inconvenient, increasing the risk of component damage during disassembly. Utility Model Content

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1: As Figures 1-13 As shown, this utility model provides an electromagnetic flowmeter with a quick-change liner, including an electromagnetic flowmeter body 1. A fixing component 2 is disposed inside the electromagnetic flowmeter body 1. The fixing component 2 includes a first fixing block 201. Three evenly arranged first fixing shafts 202 are fixedly connected to the outer surface of the first fixing block 201. A first spring 203 is disposed on the inner wall of each of the three first fixing shafts 202. One end of each of the three first springs 203 is fixedly connected to a first sliding shaft 204. A first circular groove 205 is formed on the outer surface of each of the three first sliding shafts 204. Three evenly arranged second circular grooves 206 are formed on the outer surface of the other side of the electromagnetic flowmeter body 1. A second fixing shaft 207 is fixedly connected to the inner wall of each of the three second circular grooves 206. The outer surface of the first fixing block 201 is fixedly connected to one side of the outer surface of the electromagnetic flowmeter body 1. Next, the other ends of the three first springs 203 are fixedly connected to the inner walls of the three first fixed shafts 202, and the outer surfaces of the three first sliding shafts 204 are slidably connected to the inner walls of the three first fixed shafts 202. One end of each of the three second fixed shafts 207 is rotatably connected to a rotating block 213. The outer surfaces of each of the three rotating blocks 213 are provided with a second spring 208. One end of each of the three second springs 208 is fixedly connected to the outer surfaces of the three second fixed shafts 207, and the other end of each of the three second springs 208 is fixedly connected to a moving plate 209. The inner walls of the three moving plates 209 slide against the outer surfaces of the three second fixed shafts 207, and one outer surface of each of the three moving plates 209 is fixedly connected to a second sliding shaft 210. The outer surfaces of the three second sliding shafts 210 slide against the outer surfaces of the three rotating blocks 213.

[0019] The overall effect of Embodiment 1 is that, during normal use of an electromagnetic flowmeter with a quick-replacement liner, after the inner liner 3 inside the electromagnetic flowmeter body 1 has been used for a period of time, it has experienced wear and aging. At this point, the operator needs to replace the inner liner 3. The operator needs to move the moving plate 209, which will cause the second fixing block 211 and the third fixing block 212 to move. The outer surface of the second fixing block 211 will gradually move away from the inner wall of the first circular groove 205 until the outer surface of the second fixing block 211 no longer contacts the inner wall of the first circular groove 205. At this point, the third fixing block 212 will also no longer contact the outer surface of the inner liner 3. Simultaneously, the moving plate 209 moves... During the movement, the second sliding shaft 210 will move, and the moving plate 209 will compress the second spring 208. When the second sliding shaft 210 moves, its inner wall will slide along the outer surface of the rotating block 213 until the second fixed block 211 and the third fixed block 212 are no longer located inside the electromagnetic flowmeter body 1. At this time, rotating the moving plate 209 will cause the second fixed block 211 and the third fixed block 212 to rotate. At the same time, the moving plate 209 will cause the second sliding shaft 210 to rotate, and the moving plate 209 will also cause the second spring 208 to rotate. When the second spring 208 rotates, it will cause the rotating block 213 to rotate until the second fixed block 211 and the third fixed block 212 are no longer located inside the electromagnetic flowmeter body. The old inner liner 3 is not positioned in the hollow position of the first fixed block 207, but rather on the outer surface of the electromagnetic flowmeter body 1 without affecting the inner liner 3 from sliding out from the inner wall of the electromagnetic flowmeter body 1. At this time, the moving plate 209 is released, and the tension of the second spring 208 will drive the moving plate 209 to move. The moving plate 209 will drive the outer surface of the second fixed block 211 to fit against the outer surface of the electromagnetic flowmeter body 1. Then, the worker slides the old inner liner 3 out from the inner wall of the electromagnetic flowmeter body 1, and then slides the new inner liner 3 into the electromagnetic flowmeter body 1 on the outer surface of the side with the second fixed shaft 207. At this time, the new inner liner 3 will gradually come into contact with the outer surface of the fourth fixed block 4 until one end of the new inner liner 3 fits against the outer surface of the first fixed block 201. The operator moves the movable plate 209 again, which drives the second sliding shaft 210 to move. Simultaneously, the movable plate 209 compresses the second spring 208 until the outer surface of the second fixed block 211 no longer contacts the outer surface of the electromagnetic flowmeter body 1. At this point, the operator rotates the movable plate 209 again, causing the second fixed block 211 and the third fixed block 212 to rotate. This rotation also causes the second spring 208 to rotate, which in turn causes the rotating block 213 to rotate until the second fixed block 211 is positioned in the direction of the first circular groove 205. Then, the operator stops pressing the second spring 208, and the spring force of the second spring 208 causes the movable plate 209 to move.When the movable plate 209 moves, it drives the second fixed block 211 and the third fixed block 212 to move until the outer surface of the third fixed block 212 is in contact with the outer surface of the new inner liner body 3. At this time, the outer surface of the second fixed block 211 also slides into the inner wall of the first circular groove 205. The replacement of the new inner liner body 3 is then complete. By setting the fixing component 2, the inner liner body 3 can be replaced, solving the problem that the installation and disassembly of the electromagnetic flowmeter liner is very inconvenient, thus reducing the risk of component damage during disassembly.

[0020] Example 2: As Figures 1-13 As shown, a second fixing block 211 is fixedly connected to the outer surface of each of the three movable plates 209. A third fixing block 212 is fixedly connected to the outer surface of each of the three second fixing blocks 211. The outer surfaces of the three third fixing blocks 212 are fixedly connected to the outer surfaces of the three movable plates 209 respectively. An inner liner body 3 is attached to the inner wall of the electromagnetic flowmeter body 1. Two fourth fixing blocks 4 are fixedly connected to the outer surfaces of the three first fixing shafts 202. The outer surfaces of the three third fixing blocks 212 are attached to the inner wall of the inner liner body 3. The outer surfaces of the six fourth fixing blocks 4 are attached to the inner wall of the inner liner body 3. The outer surfaces of the three second fixing blocks 211 are attached to the inner walls of the three first circular grooves 205 respectively.

[0021] The effect achieved by the entire embodiment 2 is that when replacing the inner liner body 3 of the electromagnetic flowmeter with quick-change inner liner, the operator needs to place the inner liner body 3 inside the electromagnetic flowmeter body 1. During the placement process, the inner liner body 3 will gradually come into contact with the outer surface of the fourth fixing block 4 until the outer surface of the fourth fixing block 4 is completely attached to the inner wall of the inner liner body 3. At this time, the fourth fixing block 4 and the inner liner body 3 are attached to each other, thereby increasing the stability of the inner liner body 3 and the electromagnetic flowmeter body 1, thereby ensuring the normal use of the electromagnetic flowmeter with quick-change inner liner.

[0022] Working principle: In normal use, when the operator needs to replace the inner liner body 3 of an electromagnetic flowmeter with quick-change liner, the operator needs to move the moving plate 209. The moving plate 209 will drive the second fixed block 211 and the third fixed block 212 to move until the outer surface of the second fixed block 211 is no longer in contact with the inner wall of the first circular groove 205 and the third fixed block 212 is no longer in contact with the outer surface of the inner liner body 3. At this time, rotating the moving plate 209 will drive the second fixed block 211 and the third fixed block 212 to move. The fixing block 212 rotates until the second fixing block 211 and the third fixing block 212 are no longer in the hollow position of the electromagnetic flowmeter body 1. Then, the operator slides the old inner liner body 3 out of the inner wall of the electromagnetic flowmeter body 1, and then slides the new inner liner body 3 into the electromagnetic flowmeter body 1 on the outer surface of the side with the second fixing shaft 207. At this time, the new inner liner body 3 will gradually come into contact with the outer surface of the fourth fixing block 4 until one end of the new inner liner body 3 is attached to the outer surface of the first fixing block 201, and at the same time, the fourth fixing block 212 rotates. The outer surface of the fourth fixing block 4 is completely attached to the inner wall of the inner liner body 3. At this time, the fourth fixing block 4 is attached to the inner liner body 3, which can increase the stability of the inner liner body 3 and the electromagnetic flowmeter body 1. Then, the operator rotates the moving plate 209 again. The moving plate 209 will drive the second fixing block 211 and the third fixing block 212 to rotate until the second fixing block 211 is located in the direction of the first circular groove 205. Then, the operator stops pressing the second spring 208. The elastic force of the second spring 208 will drive the moving plate 209 to move. When the moving plate 209 moves, it will drive the second fixing block 211 and the third fixing block 212 to move until the outer surface of the third fixing block 212 is attached to the outer surface of the new inner liner body 3. At this time, the outer surface of the second fixing block 211 also slides into the inner wall of the first circular groove 205. At this time, the replacement of the new inner liner body 3 is completed. By setting the fixing component 2, the inner liner body 3 can be replaced, which can prevent damage to the components of the electromagnetic flowmeter during disassembly and thus allow for quick replacement of the inner liner of the electromagnetic flowmeter.
