[0031] Working principle: Before using this electromagnetic flowmeter with moisture-proof sealing connection structure, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5As shown, a positioning assembly 2 is provided outside the plurality of fixing screws 103 and the fixing nuts 104. When the electromagnetic flowmeter body 1 and the connecting pipe 101 are installed, the connecting flange is fixed by the cooperation of the plurality of fixing screws 103 and the fixing nuts 104. Then, the two sealing covers 203 can be covered on the outer side of the fixing screws 103 and the fixing nuts 104. Then, the two positioning frames 201 can be moved to make the two positioning frames 201 close to each other. When the positioning frames 201 move, the sealing gasket 204 on the sealing cover 203 is tightly attached to the connecting flange, so that the movable rod 202 slides on the positioning frame 201 and compresses the telescopic spring 205, so that the fixing screws 103 and the fixing screws can be aligned.

After the two positioning frames 201 are moved close to each other, the U-shaped plate 208 can be put on the outer side of the two positioning frames 201. The U-shaped plate 208 can prevent the positioning frame 201 from being reset. The two positioning frames 201 can be connected to the flange for positioning, thereby improving the stability of the connection of the connecting flange. The positioning assembly 2 ensures that the connecting pipe 101 and the electromagnetic flowmeter body 1 are firmly installed, and the positioning frame 201 can be conveniently disassembled and assembled, thereby improving the convenience of operation. The fixing screw 103 and the fixing nut 104 can be sealed to prevent the thread from being corroded, avoid the difficulty of subsequent disassembly, and improve the practicality.

[0032] After the U-shaped plate 208 is fixed, the handle 211 can be pressed to drive the sliding rod 210 to slide on the fixed block 209. After the sliding rod 210 moves, the reset spring 212 can be stretched by the connecting block 213, so that the limit block 216 moves, and then the rotating block 215 is rotated so that the limit groove 217 on the rotating block 215 is aligned with the limit block 216. Then, the handle 211 can be released, and the reset spring 212 can be used to make the connecting plate 214 drive the limit block 216 to reset, so that the limit block 216 is inserted into the limit groove 217, so that the U-shaped plate 208 can be fixed. The U-shaped plate 208 is positioned to prevent the U-shaped plate 208 from falling off, thereby improving the stability of the positioning frame 201. When the electromagnetic flowmeter body 1 is disassembled later, it is only necessary to press the handle 211 to disengage the limit block 216 from the limit groove 217 and rotate the rotating block 215 so that the rotating block 215 does not block the connecting plate 214. The U-shaped plate 208 can be removed, and the positioning frame 201 loses its limit and can be removed, which is convenient for the subsequent disassembly of the positioning frame 201, thereby facilitating the disassembly and assembly of the electromagnetic flowmeter body 1 and improving convenience and practicality.
