Description

Technical Field

[0001] This utility model belongs to the technical field of electromagnetic flowmeters, specifically, it relates to an electromagnetic flowmeter with a leakage warning function. Background Technology

[0002] In an electromagnetic flowmeter, the conductive medium inside the measuring tube is analogous to the conductive metal rod in Faraday's experiment, with two electromagnetic coils at its upper and lower ends generating a constant magnetic field. When the conductive medium flows through, an induced voltage is generated. Two electrodes inside the pipe measure this induced voltage. The measuring pipe, through a non-conductive liner, achieves electromagnetic isolation from the fluid and the measuring electrodes. Its applications are very wide. However, currently available insertion-type electromagnetic flowmeters are prone to leakage during use, affecting the measured values ​​and causing unnecessary trouble for users. Furthermore, leaking fluid may damage the insertion-type electromagnetic flowmeter, reducing its service life. Application No. CN202120528515.4 discloses an insertion electromagnetic flowmeter with anti-leakage function. It utilizes a handle and screw rod to push a first baffle and a sealing block to seal the connection between the insertion tube and the tube body, preventing fluid from flowing out through gaps. Simultaneously, when the sleeve covers the extension tube, the return spring is compressed, pressing a second baffle and a sealing ring tightly against the extension tube, further preventing fluid leakage. While this method effectively prevents fluid from leaking to the outside through gaps, the mating position between the lower end of the extension tube and the tube body has an irregular surface structure. Adjusting the first baffle with the screw rod to achieve a seal at the connection point leaves gaps between the first baffles, which can affect the sealing performance.

[0003] In view of this, this utility model is proposed. Utility Model Content
