The support seat 1 is provided with a track window 2 at the top center, a support threaded rod 3 is installed in the track window 2, a locking nut 4 is installed on the support threaded rod 3, the top of the support threaded rod 3 is connected and fixed to the bottom surface of the support plate 5, and the support plate A positioning groove 6 is provided on the top of the support seat 1, a side mounting plate 7 is fixedly installed on the edge of the top surface of the support seat 1, a guide tube 8 is fixedly passed through the top of the side mounting plate 7, the end of the guide tube 8 is connected and fixed to one end of the corrugated hose 9, the other end of the corrugated hose 9 is connected and fixed to one side of the sealing connection plate 10, an electric telescopic rod 11 is fixedly installed on the outer side of the sealing connection plate 10, the central end of the electric telescopic rod 11 is connected and fixed to the side mounting plate 7, a docking port 12 is passed through the center of the sealing connection plate 10, an installation window 13 is passed through the sealing connection plate 10, and a connecting bolt 14 is arranged in the installation window 13.

[0021] The track window 2 of this example is symmetrically distributed about the center of the support seat 1, and the length of the track window 2 is greater than 3 times the thickness of the support plate 5. The above structural design enables the supporting threaded rod 3 to perform a relatively large range of horizontal displacement adjustment in the track window 2.

[0022] The supporting threaded rod 3 is symmetrically distributed about the center of the supporting plate 5, the supporting threaded rod 3 is slidably connected to the track window 2, the length of the supporting threaded rod 3 is greater than the overall height of the supporting plate 5, and locking nuts 4 are symmetrically arranged on the supporting threaded rod 3 about the center of the track window 2. The above structural design enables the supporting threaded rod 3 to carry the supporting plate 5 to adjust the horizontal and vertical positions stably along the track window 2, and to be quickly fixed by the symmetrically distributed locking nuts 4.

[0023] The support plate 5 and the sealing connection plate 10 are symmetrically distributed about the center of the support seat 1. The center of the support plate 5 and the center of the positioning groove 6 are on the same vertical line. The positioning groove 6 is set to be arc-shaped. The above-mentioned structural design enables the support plate 5 to support and position the electromagnetic flowmeter from the bottom, and the sealing connection plate 10 can be stably connected to the flanges at both ends of the electromagnetic flowmeter from both sides.

[0024] The electric telescopic rod 11 is symmetrically distributed about the center of the sealing connection disk 10, and the center of the sealing connection disk 10 and the center of the electric telescopic rod 11 are on the same horizontal plane. The above structural design enables the electric telescopic rod 11 to drive the sealing connection disk 10 to stably move horizontally and linearly, which is convenient for the installation and disassembly of the electromagnetic flowmeter.

[0025] The installation windows 13 are distributed at equal angles with respect to the center of the docking port 12. The installation windows 13 are arranged in a long strip shape.

The above structural design enables the installation windows 13 to be aligned with the holes opened on the end flanges of electromagnetic flow meters of different sizes, so as to facilitate the installation of the connecting bolts 14. At the same time, the docking port 12 facilitates the positioning and installation of the sealing connection disk 10.

[0026] Working principle: When using this device, move the support plate 5 with the support threaded rod 3 to slide horizontally along the track window 2 until the spacing of the symmetrically distributed support plates 5 is adapted to the electromagnetic flowmeter to be calibrated. Figure 2 As shown, the locking nuts 4, which are symmetrically distributed in rotation, are placed on the positioning groove 6 at the top of the support plate 5, and are away from the support seat 1, pushing the support threaded rod 3 to move vertically along the track window 2 until the center of the flange on the side of the electromagnetic flowmeter is aligned with the center of the sealing connection plate 10, and the locking nuts 4, which are symmetrically distributed in rotation, squeeze the upper and lower end surfaces of the support seat 1 to fix it;

[0027] Then, the electric telescopic rod 11 is controlled to extend, and the symmetrically distributed sealing connection disks 10 are driven to synchronously approach the flanges at both ends of the electromagnetic flowmeter until the flanges at both ends of the electromagnetic flowmeter are both inserted into the docking ports 12. The sealing connection disks 10 squeeze and fix the electromagnetic flowmeter, and the electric telescopic rod 11 is controlled to stop, and the connecting bolts 14 are passed through the installation window 13 and connected to the holes on the flanges, and the fluid conveying mechanism connected to the guide tube 8 can be started to calibrate the electromagnetic flowmeter;

[0028] After the calibration is completed, it is only necessary to remove the connecting bolts 14, control the electric telescopic rod 11 to shorten and drive the sealing connecting plate 10 to separate from the flanges at both ends of the electromagnetic flowmeter, and then remove the electromagnetic flowmeter. This is the working principle of the electromagnetic flowmeter calibration device.
