Description

Technical Field

[0001] The utility model belongs to the technical field of electromagnetic flowmeters, and in particular relates to an electromagnetic flowmeter with an auxiliary stabilizing structure. Background Art

[0002] The electromagnetic flowmeter is an instrument specially used to measure the volume flow rate of conductive fluids. It has been widely used in many industries such as chemical industry, metallurgy, water supply, and environmental protection. However, in the process of installing the electromagnetic flowmeter, compared with some pipelines, the weight of the electromagnetic flowmeter itself will be relatively large, and it is often difficult for a single person to accurately adjust the axial position of the measuring pipeline, which will not only lead to poor installation stability and improper installation, but also may cause measurement errors. In addition, the weight of the flowmeter is mainly concentrated at the flange connection, which will generate additional stress at the pipeline connection. If used for a long time, the sealing performance of the flange connection may gradually decrease, thereby bringing potential risks such as pipeline deformation or leakage. In order to avoid these problems, the utility model proposes an electromagnetic flowmeter with an auxiliary stabilizing structure.

[0003] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0009] As a preferred technical solution of the present invention, anti-slip pads are fixed to the surface of the pressure plate and one end of the nut positioning cylinder.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] The utility model can effectively support the flow meter body through the connecting rod, pipe clamp, sliding sleeve and telescopic rod, so that the axial center position of the measuring pipe of the flow meter can be easily adjusted during installation by a single person, thereby improving installation efficiency and measurement accuracy.
