As shown in fig. 1-4, the utility model provides an electromagnetic flowmeter convenient to dismouting, including being provided with the flowmeter body 100 of measuring pipe 110, still including setting up the coupling assembling at measuring pipe 110 both ends, above-mentioned coupling assembling is used for installing electromagnetic flowmeter on measurand pipeline 300.

Wherein the coupling assembly includes a coupling pipe 210 and a bolt 220.

Wherein the connection pipe 210 is disposed at one end of the measuring guide pipe 110 and movably connected with the measuring guide pipe 110. The inner side of the connection pipe 210 is provided with an internal thread so that the connection pipe 210 can be threadedly coupled with the pipe 300 to be measured through the internal thread. An annular connecting portion 211 is disposed outside the connecting tube 210, and a plurality of circular through holes 212 are opened in the connecting portion 211, and the circular through holes 212 are used for allowing the threaded ends of the bolts 220 to pass through.

The number of the bolts 220 is plural, and the threaded ends of the plural bolts 220 are respectively threaded with the measuring pipe 110 after passing through the circular through holes 212. For example, the end of the measurement duct 110 is opened with a plurality of threaded holes 111 for fitting bolts, and the bolts 220 are directly screwed with the measurement duct 110 through the threaded holes 111, as shown in fig. 2.

In use, the electromagnetic flowmeter is mounted on the pipe 300 to be measured by rotating the connecting pipe 210, and then the bolt 220 is screwed, so that the connecting pipe 210 is connected with the flowmeter body 100, and the connecting pipe 210 is sealed with the measuring pipe 110 by screwing the bolt 220.

In one embodiment, the measuring pipe 110 is provided with first annular grooves 112 at both ends thereof, the center of the first annular groove 112 coincides with the center line of the measuring pipe 110, the inner diameter of the first annular groove 112 is adapted to the outer diameter of the connecting pipe 210, and the connecting pipe 210 is inserted into the first annular groove 112.

In one embodiment, the connection assembly further includes a sealing ring 230, and the end of the connection pipe 210 facing the measurement duct 110 is opened with a second annular groove 213, and the sealing ring 230 is installed in the second annular groove 213.

After the connection pipe 210 is screwed in this way, the bolt 220 is screwed, so that the connection pipe 210 and the measuring tube 110 are in close contact by screwing the bolt 220, and the sealing ring 230 is compressed, thereby maintaining the sealing.

This structure facilitates sealing between the connection tube 210 and the measuring tube 110.

In one embodiment, an annular stop 113 is disposed within the first annular groove 112 that mates with the second annular groove 213.

Thus, in use, the annular limiting portion 113 is inserted into the second annular groove 213 and presses the sealing ring 230, thereby forming a good seal.

In one embodiment, the coupling assembly further comprises a gasket 240, the gasket 240 being arranged on a side of the connection portion 211 facing the measurement duct 110.

This compresses gasket 240 as bolt 220 is tightened, thereby providing a preload to bolt 220 to prevent bolt 220 from loosening. Meanwhile, the addition of the sealing ring 230 can make the connection pipe 210 and the measuring tube 110 connected more tightly.

If the bolt 220 is screwed to the measuring tube 110 through the screw hole 111 formed in the measuring tube 110, the circular through hole 212 must be rotated to a position corresponding to the screw hole 111, which is disadvantageous in controlling the position of the flowmeter body. Therefore, as shown in fig. 3 to 4, in one embodiment, the connection assembly further includes a nut 250, one end of the measurement duct 110 facing the connection pipe is opened with an annular sliding groove 114, the annular sliding groove 114 is a stepped groove, one side of the annular sliding groove 114 facing the bolt 220 is communicated with the outside, the plurality of nuts 250 are slidably installed in the annular sliding groove 114, and the threaded end of the bolt 220 is connected with the measurement duct 110 through the nut 250.

Thus, in use, the bolt 220 is first loosened so that the connection tube 210 can rotate freely. Then, the connection pipe 210 is rotated to connect the connection pipe 210 to the measured pipe 300. Finally, the bolt 220 is tightened to complete the installation. Therefore, the connecting pipe 210 does not need to be rotated to the position where the circular through hole 212 corresponds to the threaded hole 111 during use, and the installation can be completed.

This configuration helps to determine the orientation of the flow meter body 100.

In one embodiment, the number of circular through holes 212, bolts 220, and nuts 250 are equal and in one-to-one correspondence.

The working principle of the utility model is as follows:

in use, the bolt 220 is first loosened so that the connection pipe 210 can be freely rotated. Then, the connection pipe 210 is rotated to connect the connection pipe 210 to the measured pipe 300. Finally, the bolt 220 is tightened to complete the installation. Therefore, the connecting pipe 210 does not need to be rotated to the position where the circular through hole 212 corresponds to the threaded hole 111 during use, and the installation can be completed.

The reverse process of disassembly for assembly is not described in greater detail herein.

The utility model provides an electromagnetic flowmeter only needs to rotate connecting pipe 210 when the installation, then screw up bolt 220 can. The entire electromagnetic flow meter need not be rotated. Thereby facilitating the installation and removal of the electromagnetic flowmeter.

In the specification of the present invention, a large number of specific details are explained.
