[0036] Working principle: By starting the electric push rod 8, the electric push rod 8 can push the connecting block 9 to move in the specified direction. The movement of the connecting block 9 will drive the turntable 10 to rotate synchronously. The rotation of the turntable 10 will drive the hollow block 11 to rotate synchronously. The rotation of the hollow block 11 will be further transmitted to the push block 14, causing the push block 14 to rotate to a specific position, thereby imposing a restriction on the connecting pipe 6 and preventing it from moving. When disassembly is required, start the electric push rod 8 to make it move in the opposite direction, and the connecting block 9 moves in the opposite direction, pushing the turntable 10 to rotate in the opposite direction, thereby causing the hollow block 11 and the push block 14 to rotate in the opposite direction, gradually releasing the restriction on the connecting pipe 6 and completing the disassembly operation.

Polyurethane has extremely high impact resistance and wear resistance, and can effectively cope with impact and friction in high-wear or fluid environments containing solid particles, extending the service life of the equipment. The flexibility and elasticity of polyurethane enable it to absorb and disperse external forces, reduce the impact of mechanical stress on the equipment, and thus improve the reliability and stability of the electromagnetic flowmeter under harsh working conditions.
