Description

Technical Field

[0001] This utility model relates to the field of electromagnetic flowmeter technology, and in particular to an electromagnetic flowmeter with a moisture-proof and sealed connection structure. Background Technology

[0002] An electromagnetic flowmeter is a flow measurement instrument based on Faraday's law of electromagnetic induction and is widely used in industrial fields. It utilizes Faraday's law of electromagnetic induction: when a conductive liquid flows in a magnetic field, it cuts magnetic lines of force, generating an induced electromotive force (EMF). This induced EMF is proportional to the flow velocity. By measuring the induced EMF, the volumetric flow rate of the fluid can be calculated.

[0003] Electromagnetic flowmeters are typically used to measure conductive liquids. Since conductive liquids may generate moisture during the measurement process, and the electronic components of the electromagnetic flowmeter, such as the converter and circuit board, are very sensitive to moisture, moisture may cause short circuits, corrode electronic components, reduce insulation performance, or even cause malfunctions. Therefore, in order to ensure the service life of the electromagnetic flowmeter, sealing gaskets need to be placed at the connection points for sealing protection. However, under high pressure environments, especially when the pressure changes frequently, the seals may lose elasticity due to fatigue, leading to seal failure.

[0004] Therefore, how to design an electromagnetic flowmeter that can provide moisture-proof and sealed protection is a technical problem that engineers need to solve. Utility Model Content

[0026] refer to Figures 1 to 7 An electromagnetic flowmeter with a moisture-proof and sealed connection structure includes a device body 1 and a sealing mechanism 2. The device body 1 includes a measuring tube 101 and a flowmeter body 102. The flowmeter body 102 is installed outside the measuring tube 101, and a groove 103 is provided on the inner wall of the measuring tube 101. The sealing mechanism 2 includes a circular pad 201, an elastic support plate 203 for ensuring the sealing effect, and an adjusting spring plate 206 for adjusting the sealing effect. The circular pad 201 is installed inside the groove 103.

[0027] Specifically, the top of the circular pad 201 is provided with an elastic connecting plate 202, the inner wall of the elastic support plate 203 is connected to one end of the elastic connecting plate 202, the inner wall of the groove 103 is installed with a sealing gasket 104, the outer wall of the elastic support plate 203 is in contact with the inner wall of the sealing gasket 104, and the outer wall of the elastic support plate 203 is provided with a protective soft pad 204.

[0029] Specifically, a fixed support plate 212 is provided on the top of the circular pad 201, a fixed arc plate 213 is provided at one end of the fixed support plate 212, and an anti-slip soft pad 214 is provided on the outer wall of the fixed arc plate 213.

[0030] Specifically, a limiting block 211 is provided at the bottom of the circular pad 201, and a limiting groove 105 that matches the shape of the limiting block 211 is provided on the inner wall of the sealing gasket 104. The limiting block 211 is fixedly sleeved on the inner wall of the limiting groove 105.

[0031] Example:

[0032] In this embodiment, to address the problem that the sealing gasket 104 may lose elasticity due to fatigue and lead to seal failure when the pressure changes frequently, the technical solution of this embodiment is as follows (see reference). Figures 1 to 7 The elastic connecting plate 202 is an arc-shaped plate made of metal and has a certain degree of elasticity. The elastic connecting plate 202 is arranged in a linear array on the top of the circular pad 201. The elastic support plate 203 is an arc-shaped plate. The circular pad 201 is installed inside the sealing gasket 104. When the sealing gasket 104 is used to seal the connection, the sealing gasket 104 is squeezed, and the circular pad 201 is squeezed at the same time, thereby pushing the elastic connecting plate 202 and the elastic support plate 203 to move outward, which in turn pushes and squeezes the sealing gasket 104, so that the sealing gasket 104 is in full contact with the inner wall, thereby improving the sealing effect of the sealing gasket 104.

[0033] As a further limitation of this technical solution, the shape of the adjusting block 207 is adapted to the shape of the adjusting slot 210. The adjusting block 207 is set outside the adjusting spring plate 206 and is distributed in a linear array. By fixing the adjusting block 207 into the adjusting slot 210 at different positions, graded adjustment can be performed, and the position of the connecting plate 205 in the adjusting frame 209 can be locked.

[0034] Based on the above embodiments, when assembling the flow meter body 102 onto the measuring tube 101, by placing the sealing gasket 104 inside the groove 103, and adjusting the position of the connecting plate 205 inside the adjusting frame 207 according to the sealing requirements of the sealing gasket 104, and locking the connecting plate 205 with the adjusting block 207, the flow meter body 102 compresses the sealing gasket 104 and the circular pad 201 during assembly, thereby pushing the elastic connecting plate 202 and the elastic support plate 203 outward, which in turn pushes and compresses the sealing gasket 104, making the sealing gasket 104 fully contact the inner wall, thereby improving the sealing effect of the sealing gasket 104.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
