[0002] The split electromagnetic flowmeter is a flow measurement instrument designed based on Faraday's law of electromagnetic induction. It is mainly used to detect the volume flow of conductive liquids and slurries in closed pipes. It is used in industrial fields such as petroleum, chemical industry, metallurgy, environmental protection, and water conservancy. The device consists of a sensor and a converter. The split design allows the sensor to be installed on high-temperature and high-humidity pipelines. The converter is remotely connected via a shielded cable.

[0014] The present invention has the following beneficial effects: After the flange is installed at the end of the pipe, the present invention fixes the flange to the end of the pipe through the installation component, and uses the sensor to monitor the flow inside the pipe. After the flange is installed at the end of the pipe, the worker pushes the arc frame to slide on the surface of the semicircular plate. When the arc frame rotates, the threaded ring is driven to rotate by the telescopic rod. The threaded ring is threadedly connected to the threaded cylinder. When the arc frame pushes the threaded ring to rotate, the two threaded rings will move away from each other, thereby pushing the installation component to squeeze the pipe through the threaded ring, so that the installation component fixes the flange to the surface of the pipe through the threaded ring, thereby improving the convenience of sensor installation.

After the flange is placed at the end of the pipe, the circular arc frame is pushed to reset. At this time, the plug rod will extend toward the outer end of the circular arc hole, and the plug rod will extend through the pipe and extend to the outer end of the pipe when moving. The plug rod is fixed to the inside of the circular ring hole by the damping disk, and the plug rod is convenient to rotate through the damping disk.

At this time, when the circular arc frame is pushed to move, the cylindrical rod will pull the limit ring to move closer to each other, and the limit ring will squeeze the pipe by the clamping rod when moving, thereby fixing the flange to the end of the pipe to complete the installation, thereby improving the convenience of sensor installation and disassembly.

[0016] When the two threaded rings of the present invention move away from each other, the threaded ring pushes the contact plate to move toward the flange through the rotating ring. When the contact plate moves, it pushes the sliding rod to move toward the inside of the circular groove through the elastic frame. When the sliding rod moves, it pushes the extrusion ring to squeeze the sealing gasket. After being squeezed, the sealing gasket moves toward the outer end of the circular groove and squeezes the end of the pipeline, thereby improving the tightness of the contact between the sealing gasket and the pipeline and increasing the sealing performance between the flange and the pipeline.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
