An installation structure for an insertion electromagnetic flowmeter

Abstract

This invention relates to the field of insertion electromagnetic flowmeter technology, and more particularly to an installation structure for an insertion electromagnetic flowmeter. The installation structure includes an upper mounting pipe, a lower mounting pipe, a positioning pipe, and a connecting assembly. The upper and lower mounting pipes are detachably connected via the connecting assembly to form a ring structure, which is fitted onto the outer wall of a pipe. The upper mounting pipe has a first circular through-hole. The bottom end of the positioning pipe extends out of the first circular through-hole and can extend into an opening in the pipe. The positioning pipe has a second circular through-hole that communicates with the opening in the pipe. Because the bottom end of the positioning pipe extends out of the first circular through-hole and into the opening in the pipe, it facilitates quick positioning of the installation structure and the pipe. Furthermore, because the upper and lower mounting pipes are separate structures detachably connected via the connecting assembly, it facilitates the installation and disassembly of the installation structure from the pipe.

Description

Technical Field

[0001] This invention relates to the field of insertion electromagnetic flowmeter technology, and more particularly to an installation structure for an insertion electromagnetic flowmeter. Background Art

[0002] Currently, insertion flow meters are widely used in fluid measurement. Commonly used insertion flow meters include a probe rod, base, ball valve, etc. The mounting base is connected to the pipeline, and the probe rod is inserted into the pipeline to detect the fluid in the pipeline. Insertion flow meters directly insert the monitoring sensor part into the measuring pipeline. Due to their simple installation and convenient maintenance, they are widely used in the market.

[0003] The existing method of connecting insertion electromagnetic flowmeters to pipelines is generally to weld the connecting pipe around the pipeline through hole, and then connect and fix the ball valve of the insertion electromagnetic flowmeter to the connecting pipe by thread. Although this method has a good fixing effect, it is time-consuming and labor-intensive when installing insertion electromagnetic flowmeters on site. Summary of the Invention

[0031] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0032] like Figure 1 As shown, the present invention provides an installation structure for an insertion-type electromagnetic flowmeter, including an upper mounting pipe 1, a lower mounting pipe 2, a positioning pipe 3, and a connecting assembly 4. The upper mounting pipe 1 and the lower mounting pipe 2 are detachably connected via the connecting assembly 4, forming a ring structure. This ring structure is fitted onto the outer wall of a pipe 5. The upper mounting pipe 1 has a first circular through-hole 11. The bottom end of the positioning pipe 3 extends out of the first circular through-hole 11 and can extend into an opening 51 on the pipe 5. The positioning pipe 3 has a second circular through-hole 31, which communicates with the opening 51 on the pipe 5. In this embodiment, the length of the positioning pipe 3 is determined by the upper mounting pipe 1, the distance between the upper mounting pipe 1 and the pipe 5, and the wall thickness of the pipe 5, thus ensuring that the bottom end of the positioning pipe 3 can extend into the opening 51 on the pipe 5. Furthermore, in this embodiment, all through-holes are circular to facilitate the installation of a cylindrical probe rod.

[0033] It should be noted that in actual application, the probe rod of the insertion electromagnetic flowmeter enters the opening 51 on the pipe 5 through the second circular through hole 31 in the mounting structure for measurement.

[0034] The installation structure of the insertion electromagnetic flowmeter provided in this embodiment has a positioning tube 3. The bottom end of the positioning tube 3 extends out of the first circular through hole 11 and into the opening 51 on the pipe 5, which facilitates the quick positioning of the installation structure and the pipe 5. At the same time, since the upper installation tube 1 and the lower installation tube 2 are separate structures and can be detachably connected by the connecting component 4, it is convenient to install and disassemble the installation structure and the pipe 5, thereby improving the installation and disassembly speed of the insertion electromagnetic flowmeter.

[0035] like Figure 2 As shown, the positioning tube 3 includes a connected tube body 32 and a limiting ring 33. The limiting ring 33 is sleeved on the outer wall of the tube body 32. The top end of the tube body 32 and the top end of the limiting ring 33 are on the same plane, and the bottom end of the tube body 32 is lower than the bottom end of the limiting ring 33. The tube body 32 and the limiting ring 33 are integrally formed and form a rotating structure. The outer diameter of the limiting ring 33 is larger than the diameter of the first circular through hole 11. The tube body 32 of the positioning tube 3 passes through the first circular through hole 11 of the upper mounting tube 1 and enters the opening 51 on the pipe 5 to form a positioning with the pipe 5. The lower end of the limiting ring 33 on the positioning tube 3 abuts against the top end of the upper mounting tube 1 to prevent the positioning tube 3 from falling into the pipe 5.

[0036] In practical applications, the installation structure of the insertion electromagnetic flowmeter also includes a connector (not shown), which can be used to connect the positioning tube 3 to the upper mounting tube 1.

[0037] like Figure 3 As shown, the upper mounting tube 1 includes a first arc-shaped body 12 and first mounting portions 13 disposed on both sides of the first arc-shaped body 12, and a first circular through hole 11 is disposed on the first arc-shaped body 12. Figure 4 As shown, the lower mounting tube 2 includes a second arc-shaped main body 21 and second mounting portions 22 disposed on both sides of the second arc-shaped main body 21. The first arc-shaped main body 12 and the second arc-shaped main body 21 are joined to form a ring structure; the first mounting portions 13 on both sides of the first arc-shaped main body 12 and the second mounting portions 22 on both sides of the second arc-shaped main body 21 are joined together and then connected by a connecting assembly 4.

[0038] The upper mounting tube 1 also includes a connecting part 14, which is a cylindrical structure. The connecting part 14 is located above the first circular through hole 11. A third circular through hole 141 is provided inside the connecting part 14. The third circular through hole 141 communicates with the first circular through hole 11 and is coaxially arranged with the first circular through hole 11. The diameter of the third circular through hole 141 is larger than the diameter of the first circular through hole 11, thereby forming a step between the first circular through hole 11 and the third circular through hole 141 to facilitate the positioning of the limiting ring 33 on the positioning tube 3.

[0039] In this embodiment, the connecting component 4 is a bolt 41 and a nut 42; the bolt 41 passes through the first mounting part 13 and the second mounting part 22 and is connected to the nut 42 to connect the upper mounting tube 1 and the lower mounting tube 2.

[0040] To ensure the sealing between the opening 51 of the pipe 5 and the positioning tube 3, the installation structure of the insertion electromagnetic flowmeter also includes a sealing gasket 6. The sealing gasket 6 is placed between the upper mounting tube 1 and the pipe 5. The bottom end of the positioning tube 3 passes through the upper mounting tube 1 and the sealing gasket 6 in sequence and connects to the opening 51 on the pipe 5.
