This design solves the problem that the original electromagnetic flowmeter sealed shell is not convenient to install.

[0021] As the first embodiment of the utility model: a connecting flange 61 is welded at the end of the transport pipeline body 6, and a plurality of through holes 62 are provided on the surface of the connecting flange 61. Two groups of docking flanges 4 are provided with the same specifications. A positioning column 41 is provided at one end of the docking flange 4 which is relatively far away from the electromagnetic flowmeter body 2. The positioning column 41 corresponds to the position of the through hole 62 one by one. The docking flange 4 is positioned and docked with the connecting flange 61 through the positioning column 41 and the through hole 62. The positioning column 41 can prevent the docking flange 4 from deflecting and rotating after docking with the connecting flange 61, thereby facilitating the installation between the transport pipeline body 6 and the connecting pipeline 1. The connecting flange 61 and the docking flange 4 are tightly engaged with the sealing cavity 9. A sealing gasket 91 is bonded inside the sealing cavity 9. The sealing gasket 91 is made of wear-resistant rubber. The first sealing shell 7 and the second sealing shell 8 can clamp and limit the connecting flange 61 and the docking flange 4 through the sealing cavity 9, and The connection between the docking flange 4 and the connecting flange 61 is sealed by the sealing gasket 91 inside the sealing cavity 9. The first sealing shell 7 is rotatably provided with a rotating adjusting head 72 at the upper and lower ends. A threaded bolt 71 is provided on the inner side of the rotating adjusting head 72. The rotating adjusting head 72 can drive the threaded bolt 71 to rotate together. The second sealing shell 8 is symmetrically provided with threaded holes 81 at the upper and lower ends. The threaded bolt 71 and the threaded hole 81 are meshed with each other. The rotation of the threaded bolt 71 can drive the first sealing shell 7 and the second sealing shell 8 to be relatively close or away from each other through the threaded hole 81. A limiting nut 82 is provided at the end of the threaded bolt 71. The limiting nut 82 can further limit and fix the threaded bolt 71. The outer diameter of the sealing butt joint pipe 5 is equal to the inner diameter of the transport pipeline body 6. The sealing butt joint pipe 5 is tightly engaged with the inner wall of the transport pipeline body 6. The sealing butt joint pipe 5 can enhance the sealing performance of the connection between the transport pipeline body 6 and the connecting pipeline 1.

[0022] As a second embodiment of the utility model: the user aligns the docking port 3 of the connecting pipe 1 with the end of the transport pipe body 6, and inserts the sealing docking pipe 5 into the inner wall of the transport pipe body 6, then rotates the connecting pipe 1 and makes the positioning column 41 on the surface of the docking flange 4 insert into the through hole 62 on the surface of the connecting flange 61, and then the docking of the connecting pipe 1 and the transport pipe body 6 is preliminarily completed, and then the matching first sealing shell 7 and the second sealing shell 8 are taken out, and the first sealing shell 7 is first aligned with the connecting flange 61 and the docking flange 4, and is inserted into the sealing cavity 9, and then the second sealing shell 8 is inserted into the sealing cavity 9. In the same way, the other end of the connecting flange 61 and the docking flange 4 are inserted, and the threaded bolt 71 corresponds to the threaded hole 81. At this time, a tool is used to rotate the adjusting head 72, and the rotating adjusting head 72 drives the threaded bolt 71 to rotate together. Since the threaded bolt 71 and the threaded hole 81 are engaged with each other, the rotation of the threaded bolt 71 drives the first sealing shell 7 and the second sealing shell 8 to get closer through the threaded hole 81, thereby clamping and fixing the connecting flange 61 and the docking flange 4, and further sealing the connection between the connecting flange 61 and the docking flange 4 through the sealing gasket 91 arranged inside the sealing cavity 9.
