[0038] Electromagnetic flowmeter is a new type of flow measurement instrument that has developed rapidly with the development of electronic technology. Electromagnetic flowmeter uses the principle of electromagnetic induction to measure the flow rate of conductive fluid based on the electromotive force induced when the conductive fluid passes through an external magnetic field. However, electromagnetic flowmeter can only detect the flow rate of conductive materials, and because the sensor electrode surface is always in contact with the liquid, the electrode surface is easily contaminated over time and requires frequent maintenance.
[0039] Example 1
[0040] Reference Figures 1 to 3, which is the first embodiment of the present invention, provides an integrated instrument detection device, which avoids the contamination of the sensing component 302 during use by placing the sensing component 302 inside and not directly contacting the substance to be detected, thereby reducing the maintenance cost.
[0041] Specifically, the integrated instrument detection device includes an instrument panel unit 100, a connecting conduit 200 and a measuring unit 300. Connecting flanges 203 are provided on both sides of the connecting conduit 200, which are connected to the pipeline to be measured through the connecting flanges 203. The specifications of the connecting flanges 203 can be selected as required, such as a flange with a caliber of DN10-250 and a rated pressure of ≤1.6Mpa, or a flange with a caliber of DN250-1000 and a rated pressure of ≤1.0Mpa. The measuring unit 300 is arranged in the inner cavity of the connecting conduit 200 and is connected to the instrument panel unit 100, and converts the induced potential signal detected in the connecting conduit 200 into a unified standard DC signal and displays it through the instrument panel unit 100.
[0042] Based on the above, the instrument panel unit 100 includes a display dial 101 and a connecting component 102. The display dial 101 is installed on the connecting tube 200 through the connecting component 102. The display dial 101 is a screen-type instrument panel that can be used for parameter setting and display measurement data. The connecting component 102 includes an extension rod 102a. One end of the extension rod 102a is connected to the display dial 101, and the other end passes through the connecting tube 200 and is connected to the measuring unit 300 arranged inside the connecting tube 200.

The moving shaft 301a follows the rotation, and the rotating shaft 301a is rotatably sleeved on the fixed rotating shaft 102b. The rotating shaft 301a is a hollow cavity. The induction component 302 includes a magnetic pole 302a installed on the inner cavity wall of the rotating shaft 301a and a coil 302b arranged at one end of the fixed rotating shaft 102b. The coil 302b is placed in the inner cavity of the rotating shaft 301a and is electrically connected to the converter 303. The magnetic pole 302a is a permanent magnet or a uniform DC or AC magnetic field generated by the excitation of a 50HZ industrial frequency power supply. The rotating component 301 drives the magnetic pole 302a to rotate around the coil 302b, and an induced potential is formed by cutting the magnetic lines of force between the two. The induced potential signal is converted into a standard DC signal through the converter 303.
[0044] Based on the above, the rotating component 301 is made of ferromagnetic material to isolate the interference of the external magnetic field to avoid affecting the detection, and the outer wall of the rotating component 301 is a complete insulating lining, which directly contacts the liquid to be measured to prevent the induced potential generated in the sensing component 302 from being short-circuited by the metal rotating component 301.
[0045] Example 2
[0046] Reference Figure 4 , which is the second embodiment of the present invention. Different from the previous embodiment, in this embodiment, when the substance to be tested is liquid and cannot fill the connecting catheter body, detection can also be performed by adjusting the radial position of the measuring unit 300 in the connecting catheter 200, and the scope of use is wide.
[0047] Specifically, the connecting assembly 102 also includes an adjusting sleeve 102c installed on the outer wall of the connecting conduit 200. In this embodiment, the adjusting sleeve 102c is installed on the mounting base 204 on the side wall of the connecting conduit 200 through a fixing flange 102c-1. The adjusting sleeve 102c is sleeved on the outside of the extension rod 102a. The extension rod 102a slides in the adjusting sleeve 102c, driving the measuring unit 300 connected to the extension rod 102a to move radially in the connecting conduit 200.
[0048] Furthermore, the adjusting sleeve 102c includes an adjusting member 102c-2 and a through rod 102c-3, the adjusting member 102c-2 is rotatably arranged on the upper part of the outer wall surface of the through rod 102c-3, and at the same time, the adjusting member 102c-2 is sleeved on the outside of the extension rod 102a, and the through rod 102c-3 is fixed to the base 204 through a fixing flange 102c-1, and one end of the extension rod 102a is provided with an external thread, and the other end is a smooth rod, and a limit ring 102a-1 is provided at the intersection of the two, and an external thread is provided on the outer wall of the extension rod 102a. A slide groove 102a-2 is also provided on the surface, and an internal thread is provided on the inner wall surface of the adjusting member 102c-2, which is threadedly connected to the extension rod 102a. A hole is opened in the middle of the through rod 102c-3, and a slider 102c-4 is provided on the upper part of the inner wall of the through rod 102c-3. The vertical distance between the slider 102c-4 and the central axis of the through rod 102c-3 is smaller than the outer diameter of the limit ring 102a-1. It should be noted that the aperture below the slider 102c-4 in the through rod 102c-3 must be equal to the outer diameter of the limit ring 102a-1.
[0049] Working process: When the substance to be measured is liquid and cannot fill the connecting catheter body, the adjusting piece 102c-2 can be rotated, and the slide groove 102a-2 of the extension rod 102a cooperates with the slider 102c-4 to move up and down in the adjusting sleeve 102c to adjust the radial position of the measuring unit 300 in the connecting catheter 200. The extension rod 102a is restricted by the limiting ring 102a-1 and will not separate from the adjusting sleeve 102c.
[0050] Example 3
[0051] Reference Figure 5 , 6 , which is the third embodiment of the present invention. Different from the previous embodiment, in this embodiment, the base 204 connected to the adjusting sleeve 102c is rotatably arranged on the outer wall of the connecting duct 200 through the mounting assembly 201. The instrument panel unit 100 and the measuring unit 300 can be removed from the connecting duct 200 without blocking the flow in the connecting duct 200. The operation is convenient, the work is not affected, and the maintenance and repair of the instrument are convenient.
[0052] Furthermore, the lower part of the adjusting sleeve 102c is movably installed on the outer wall of the connecting duct 200 through the installing assembly 201, and the installing assembly 201 includes a fixing ring 201a and a connecting ring 201b. The fixing ring 201a is symmetrically arranged in two groups on the outer wall of the connecting duct 200. Annular guide blocks 201a-1 are arranged on the opposite surfaces of the two groups of fixing rings 201a. Guide grooves 201b-4 cooperating with the annular guide blocks 201a-1 are provided on both end surfaces of the connecting ring 201b. The connecting ring 201b is rotatably arranged between the two groups of fixing rings 201a through the cooperation of the annular guide blocks 201a-1 and the guide grooves 201b-4. The lower part of the base 204 is fixed to the outer wall surface of the connecting ring 201b, that is, the adjusting sleeve 102c connected to the base 204 rotates with the rotation of the connecting ring 201b. The connecting ring 201b is fixed to the connecting conduit 200 through the positioning hole 205 and the positioning bolt 206. It should be noted that the connecting ring 201b is provided with a through hole 201b-3 for the extension rod 102a to slide in. Correspondingly, the connecting conduit 200 is provided with a measuring hole 202, and the extension rod 102a equipped with the measuring unit 300 passes through the through hole 201b-3 and the measuring hole 202 and extends into the inner cavity of the connecting conduit 200 for detection.
[0053] Specific working process: when installing the instrument panel unit 100 and the measuring unit 300, rotate the adjusting member 102c-2 to move the extension rod 102a upward until the upper end surface of the limit ring 102a-1 contacts the lower end surface of the slider 102c-4, fix the adjusting sleeve 102c to the base 204 through the fixing flange 102c-1, and the fixed measuring unit 300 does not contact the outer wall surface of the connecting conduit 200, rotate the connecting ring 201b to make the through hole 201b-3 and the measuring hole 202 face each other, align the positioning bolt 206 with the positioning hole 205 and fix it, and then rotate the adjusting member 102c-2 to adjust the radial position of the measuring unit 300 in the connecting conduit 200; when installing the instrument panel unit 100 and the measuring unit 300, rotate the adjusting member 102c-2 to adjust the radial position of the measuring unit 300 in the connecting conduit 200; When disassembling the instrument panel unit 100 and the measuring unit 300, rotate the adjusting member 102c-2 to move the extension rod 102a upward until the upper end surface of the limiting ring 102a-1 contacts the lower end surface of the slider 102c-4, and move the measuring unit 300 out of the connecting conduit 200, so that during the rotation of the connecting ring 201b, the measuring unit 300 will not collide and wear with the connecting conduit 200. At this time, remove the positioning bolt 206, rotate the connecting ring 201b, and drive the instrument panel unit 100 and the measuring unit 300 to rotate together. When the through hole 201b-3 and the measuring hole 202 are offset, remove the bolts connecting the fixing flange 102c-1 and the base 204, and remove the instrument panel unit 100 and the measuring unit 300.
[0054] Example 4
[0055] Reference Figure 7, which is the fourth embodiment of the present invention. Different from the previous embodiment, this embodiment changes the complicated bolt connection between the fixed flange 102c-1 and the base 204 into a simple disassembly method, which has a simple structure, is easy to operate, and is more in line with usage habits.
[0056] Specifically, the connecting ring 201b is divided into a disassembly ring 201b-1 and a rotating ring 201b-2. The two ends of the disassembly ring 201b-1 and the rotating ring 201b-2 are arranged to be stepped to match each other. A clamping block 201b-5 is arranged on the stepped surface where one end of the disassembly ring 201b-1 contacts the rotating ring 201b-2. Similarly, a clamping groove 201b-6 matching with the one end of the rotating ring 201b-2 is arranged on the contact surface. In this embodiment, the base 204 is arranged on the outer wall surface of the disassembly ring 201b-1, and the through hole 201b-3 is opened on the disassembly ring 201b-1.
[0057] It should be noted that the annular guide blocks 201a-1 provided on the two sets of fixing rings 201a are open annular structures, and the open area is larger than the area where the guide grooves 201b-4 on the disassembly ring 201b-1 are located.
[0058] Specific working process: when installing the instrument panel unit 100 and the measuring unit 300, the instrument panel unit 100 and the measuring unit 300 installed with the adjusting sleeve 102c are installed and fixed together with the base 204 on the disassembly ring 201b-1 that has been removed. After fixing, the block 201b-5 of the disassembly ring 201b-1 is engaged with the slot 201b-6, and the disassembly ring 201b-1 is pushed along the annular guide block 201a-1, driving the rotating ring 201b-2 to rotate around the connecting guide tube 200, so that the through hole 201b-3 on the disassembly ring 201b-1 is opposite to the measuring hole 202, and the positioning bolt 206 is aligned with the positioning hole 205 and fixed; the disassembly process is the opposite of it, which will not be repeated here.
[0059] The specific principles are:
[0060] When installing the instrument panel unit 100 and the measuring unit 300, rotate the adjusting member 102c-2 to move the extension rod 102a upward until the upper end surface of the limit ring 102a-1 contacts the lower end surface of the slider 102c-4, and fix the instrument panel unit 100 and the measuring unit 300 installed with the adjusting sleeve 102c together with the base 204 on the disassembled disassembly ring 201b-1, rotate the connecting ring 201b to make the through hole 201b-3 and the measuring hole 202 face each other, align the positioning bolt 206 with the positioning hole 205 and fix it, and engage the block 201b-5 of the disassembly ring 201b-1 with the slot 201b-6, and push the disassembly ring 201b-1 along the annular guide block 201a-1, driving the rotating ring 201b-2 to rotate around the connecting guide tube 200, so that the disassembly ring 201b-1 can be easily connected to the measuring unit 300. The through hole 201b-3 on the ring 201b-1 is opposite to the measuring hole 202. At this time, the guide groove 201b-4 on the disassembly ring 201b-1 slides onto the annular guide block 201a-1 to control the disassembly ring 201b-1 not to separate from the fixing ring 201a. The positioning bolt 206 is aligned with the positioning hole 205 and fixed to fix the connecting ring 201b on the connecting conduit 200. The adjusting member 102c-2 is rotated as needed, and the slide groove 102a-2 of the extension rod 102a cooperates with the slider 102c-4 and moves up and down in the adjusting sleeve 102c to adjust the radial position of the measuring unit 300 in the connecting conduit 200 to obtain more accurate data. When the substance to be measured is liquid and cannot fill the connecting conduit body, measurement can also be performed by adjusting the measuring unit 300.
[0061] When the substance to be detected flows through the connecting conduit 200, the rotating component 301 rotates around the fixed rotating shaft 102b, driving the magnetic pole 302a on the inner wall of the rotating shaft 301a to rotate. The magnetic pole 302a generates a uniform DC or AC magnetic field. When the magnetic pole 302a rotates around the coil 302b, it moves by cutting the magnetic lines of force between the two to form an induced potential. The induced potential signal is converted into a standard DC signal through the converter 303, transmitted to the instrument panel unit 100, and displayed on the display dial 101.
[0062] When disassembling the instrument panel unit 100 and the measuring unit 300, the adjusting member 102c-2 is rotated to move the extension rod 102a upward until the upper end surface of the stop ring 102a-1 contacts the lower end surface of the slider 102c-4, and the measuring unit 300 is moved out of the connecting conduit 200, so that the measuring unit 300 will not collide and wear with the connecting conduit 200 during the rotation of the connecting ring 201b. At this time, the positioning bolt 206 is removed, and the connecting ring 201b is rotated to drive the instrument panel unit 100. Rotate together with the measuring unit 300. When the through hole 201b-3 and the measuring hole 202 are offset, and the guide groove 201b-4 on the disassembly ring 201b-1 is in the unclosed area of the annular guide block 201a-1, remove the disassembly ring 201b-1. The disassembly work is now completed. If further disassembly is required, remove the bolts connecting the fixed flange 102c-1 and the base 204, and the instrument panel unit 100 and the measuring unit 300 can be removed. The structure is simple, the operation is convenient, and it is easy to maintain and overhaul.
[0063] To sum up, by placing the sensing component 302 inside and not in direct contact with the substance to be measured, the sensing component 302 is prevented from being contaminated during use, thereby reducing the maintenance cost. Moreover, when the substance to be measured is a liquid and cannot fill the connecting conduit body, detection can also be performed by adjusting the radial position of the measuring unit 300 in the connecting conduit 200, and the scope of use is wide. The base 204 connected to the adjusting sleeve 102c is rotatably set on the outer wall of the connecting conduit 200 through the mounting component 201. The instrument panel unit 100 and the measuring unit 300 can be removed from the connecting conduit 200 without blocking the flow in the connecting conduit 200. The operation is convenient, the work is not affected, and the maintenance and repair of the instrument are convenient. The cumbersome bolt connection between the fixed flange 102c-1 and the base 204 is changed to a simple disassembly method, which has a simple structure, is easy to operate, and is more in line with usage habits.
[0064] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
