Description

Technical Field

[0001] The present invention relates to the technical field of flow measurement, and in particular to an electromagnetic flowmeter with remote control. Background Art

[0002] The electromagnetic flowmeter is a flowmeter that measures flow based on Faraday's law of electromagnetic induction. It calculates the flow rate of the fluid in the pipeline and determines the flow rate by measuring the induced electromotive force generated on the electrodes on both sides of the measuring tube when the fluid cuts the magnetic lines of force in the magnetic field.

[0003] In order to accurately measure the flow rate of liquid in the pipeline, it is necessary to ensure that the fluid passing through the electromagnetic flowmeter is in a fully loaded state as much as possible. Therefore, in theory, the smaller the diameter of the measuring tube in the electromagnetic flowmeter, the more accurate the measurement result. However, in actual application, the transport flow rate of the liquid in the transport pipe is different according to different usage requirements. If only a small-diameter measuring tube is used for electromagnetic flow counting, when transporting a large flow of liquid, the liquid will accumulate in the transport pipe. In particular, when transporting high-density, high-quality liquids, additional damage will be caused to the transport pipe, increasing the hydraulic pressure in the transport pipe, resulting in leakage, over-pressure damage, etc. Conversely, if only a large-diameter measuring tube is used for electromagnetic flow counting, when transporting a small flow of liquid, the liquid will not be fully loaded through the measuring tube, thereby causing measurement errors. Therefore, the present application provides an electromagnetic flowmeter with remote control to meet the needs. Summary of the invention

The anti-touch component 120 includes a circular plate 121, an annular groove 122 is formed on the outer wall of the circular plate 121, an elastic sealing film 123 is sealed and fixedly installed on the inner wall of the right chamber of the top box 115, and the inner wall of the elastic sealing film 123 is sealed and fixedly connected to the inner wall of the annular groove 122, the circular plate 121 is movably connected to the inner wall of the top box 115 through the elastic sealing film 123, the elastic sealing film 123 can effectively prevent the liquid in the outflow pipe 114 from flowing into the top box 115, a receiving ball 124 is fixedly installed at the bottom of the circular plate 121, and the receiving ball 124 is movably contacted with the inner wall of the elliptical groove 116, the elliptical groove 116 is used to limit the receiving ball 124, and a touch rod 125 is fixedly installed at the bottom of the receiving ball 124, and the touch rod 125 is located inside the outflow pipe 114. A base 126 is fixedly installed on the top of the circular plate 121, and rotating rods 140 are fixedly installed on both side walls of the base 126. The two groups of rotating rods 140 are respectively located inside the two groups of arc-shaped inner grooves 117, and are slidably connected to the inner walls of the arc-shaped inner grooves 117. An arc-shaped tooth 127 is fixedly installed at the center of the top of the base 126, and arc-shaped baffles 128 are fixedly installed on the top of both sides of the base 126. The top of both sides of the base 126 is fixedly installed with limited seats 129 by bolts.The top of the base 126 is provided with an arc-shaped top platform 130, the end wall of the arc-shaped top platform 130 is connected to the output end of the angle sensor 134, and the arc-shaped clamping tooth 2 131 is fixedly installed at the center of the bottom of the arc-shaped top platform 130, and the arc-shaped clamping tooth 2 131 is clamped with the arc-shaped clamping tooth 1 127, and the base 126 is fixedly connected to the arc-shaped top platform 130 through the cooperation of the arc-shaped clamping tooth 2 131 and the arc-shaped clamping tooth 1 127, the bottoms of both ends of the arc-shaped top platform 130 cooperate with the two sides of the base 126, and the side walls of both ends of the arc-shaped top platform 130 are respectively in contact with the two groups of arc-shaped baffles 128, and the arc-shaped top platform 130 The side walls at both ends are provided with side grooves 132 and bottom grooves 133, and the side grooves 132 and bottom grooves 133 are clamped with the corresponding limit seats 129. In the present invention, when the liquid level in the flange pipe 170 reaches the preset value of the liquid level detector 171, and after being buffered by the inner pipe 160, the liquid in the inner pipe 160 flows into the outflow pipe 114 through the liquid outlet 161, and impacts the feeler rod 125. Under the limiting effect of the elliptical groove 116, the feeler rod 125 drives the impacted ball 124 to rotate, thereby driving the circular plate 121, the base 126 and The arc top platform 130 rotates, and the angle sensor 134 can detect the rotation angle of the arc top platform 130. When the rotation angle of the arc top platform 130 reaches a preset value, the central control center 111 will send an electrical signal to the solenoid valve 1 210, so that the solenoid valve 1 210 is opened and the solenoid valve 220 is closed. At this time, the fluid entering the inner pipe 160 can enter the main branch pipe 240 from the liquid outlet 161. In this process, the electromagnetic sensor component 230 can detect the flow rate of the fluid entering the main branch pipe 240. Since the flow rate of the fluid is large, the liquid The body is in a fully loaded state when entering the main branch pipe 240, and is suitable for large-flow fluid detection. At the same time, it can relieve the hydraulic pressure inside the transport pipeline and prevent accidents such as pipeline blockage and over-pressure damage. In particular, during the measurement process, the deflection angle of the feeler rod 125 can be freely adjusted according to the aperture of the liquid separation port 163, and the aperture of the liquid separation port 163 is proportional to the deflection angle of the feeler rod 125. At the same time, it is necessary to ensure that after the arc-shaped clamping tooth 131 is engaged with the arc-shaped clamping tooth 127, the angle of the arc-shaped top platform 130 is horizontal, so as to facilitate the observation of the value of the angle sensor 134.

[0040] In this embodiment, if Figure 7 and Figure 8As shown, a flange pipe 151 is fixedly installed at the input port at the end of the rear component 150, a flange pipe 2 170 is fixedly installed at the input port at the end of the flange pipe 151, a liquid level detector 171 is fixedly installed on the inner wall of the top of the flange pipe 2 170, and the liquid level detector 171 is electrically connected to the central control center 111. The liquid level detector 171 can detect the liquid level entering the inner pipe 160, so as to determine whether the liquid outlet 163 can quickly discharge the liquid level in the inner pipe 160. When the liquid level in the flange pipe 2 170 does not reach the preset value of the liquid level detector 171, the central control center 111 sends an electrical signal to the solenoid valve 1 210, so that the solenoid valve 1 210 is closed and the solenoid valve 220 is opened. At this time, the fluid entering the inner pipe 160 can enter the branch pipe 250 from the liquid separation port 163, and then enter the main branch pipe 240 through the check valve 260 on the branch pipe 250. During this process, the electromagnetic sensor assembly 230 can detect the flow of the fluid entering the branch pipe 250. Since the apertures of the branch pipe 250 and the liquid separation port 163 are much smaller than the apertures of the main branch pipe 240 and the liquid outlet 161, the liquid is in a full load state when entering the branch pipe 250. It is suitable for fluid detection with a small flow rate, and can effectively prevent liquid from being discharged from the liquid outlet 161 due to too small a liquid flow rate, thereby causing the liquid to be in an underloaded state when flowing through the guide pipe 231, resulting in inaccurate results.

[0041] As an implementation method in this embodiment, Figures 5 to 9 As shown, a shunt pipe 112 is fixedly installed at the bottom of the front component 110, the outer wall of the inner pipe 160 is clamped with the inner walls of the front component 110 and the rear component 150, the output port of the liquid outlet 161 is connected to the inside of the outflow pipe 114, the output port of the liquid separator 163 is connected to the inside of the shunt pipe 112, and a liquid inlet 162 is opened on the end wall of the inner pipe 160, and the liquid inlet 162 is connected to the inside of the flange pipe 151. In the present invention, when the liquid enters the liquid inlet 162, the fluid can flow out from the liquid outlet 161 and the liquid separator 163 according to the actual flow rate of the liquid.

[0042] A liquid separation pipe 164 is fixedly installed at the bottom of the inner pipe 160, and the two ends of the liquid separation pipe 164 are respectively connected with the inner pipe 160 and the liquid separation port 163. The liquid separation pipe 164 seals and penetrates the rear component 150, the front component 110 and the shunt pipe 112. A conducting hole 113 is opened at the bottom of the front component 110. A temperature sensor 165 is fixedly installed on the inner wall of the conducting hole 113, and the output end of the temperature sensor 165 is connected with the inside of the liquid separation pipe 164. The temperature sensor 165 is electrically connected to the central control center 111. In the present invention, since temperature changes will affect the density and conductivity of the fluid, it is necessary to adjust the detection structure of the flow meter through temperature compensation to eliminate the error caused by temperature changes. Therefore, In order to calculate the conductivity with high precision, it is necessary to measure the fluid temperature to correct the measured value of the conductivity. When the liquid flows into the inner pipe 160 from the liquid inlet 162, the liquid can flow into the liquid separation port 163 from the liquid separation pipe 164. At this time, the temperature sensor 165 connected to the inside of the liquid separation pipe 164 can detect the temperature of the liquid. In particular, when the hydraulic pressure of the fluid in the inner pipe 160 is too large, if the temperature sensor 165 is directly tested with the fluid, the excessive pressure will damage the temperature sensor 165. At this time, the fluid in the inner pipe 160 is diverted, and part of the liquid is introduced into the liquid separation pipe 164 for temperature testing, which can effectively prevent the temperature sensor 165 from being damaged by high pressure.

[0043] As an implementation method in this embodiment, Figures 2 to 4 As shown, the outlet of the outflow pipe 114 and the outlet of the shunt pipe 112 are respectively fixedly installed with a solenoid valve 1 210 and a solenoid valve 2 220, and the output ports of the solenoid valve 1 210 and the solenoid valve 2 220 are respectively connected to two sets of electromagnetic sensor components 230. Under normal conditions, the solenoid valve 1 210 is in a closed state, and the solenoid valve 2 220 is in an open state, that is, the fluid always enters the branch pipe 250 from the liquid separation port 163. Since the diameter of the branch pipe 250 is much smaller than the diameter of the main branch pipe 240, the liquid is always in a full load state when entering the branch pipe 250, and its electric The detection result of the magnetic sensor component 230 is relatively accurate. The main branch pipe 240 is fixedly installed on the top output port of the electromagnetic sensor component 230, and the branch pipe 250 is fixedly installed on the bottom output port of the electromagnetic sensor component 230. The other pipe mouth of the branch pipe 250 is fixedly installed with a check valve 260. When the solenoid valve 1 210 is in the open state and the solenoid valve 2 220 is in the closed state, the check valve 260 is in the open state, which can prevent the liquid in the main branch pipe 240 from flowing back into the branch pipe 250, and the other valve mouth of the check valve 260 is connected to the inside of the main branch pipe 240.

[0044] The electromagnetic sensor assembly 230 includes a flow guide tube 231, flanges 232 are fixedly installed at both ends of the flow guide tube 231, and the flanges 232 are connected to the corresponding external devices. Liners 233 are fixedly installed on the inner walls of both ends of the flow guide tube 231, support plates 234 are fixedly installed on the top and bottom outer walls of the flow guide tube 231, and electrodes 235 are fixedly installed on the surrounding walls of the flow guide tube 231. The electrodes 235 can generate induced electromotive force, and coils 236 are wound around the outer walls of the two groups of support plates 234. The coils 236 can form an external magnetic field. Silicon steel sheets 237 are fixedly installed on the tops of the two groups of support plates 234. The silicon steel sheets 237 have good magnetic permeability and anti-hysteresis loss characteristics. The outer wall of the flow guide tube 231 is sleeved with an annular cover plate 238, and the electrode 235 is electrically connected to the central control center 111. In the present invention, the working principle of the electromagnetic sensor assembly 230 is based on Faraday's law of electromagnetic induction. When the conductive fluid passes through the magnetic field formed by the coil 236, An induced electromotive force will be generated on the electrode 235, and this electromotive force is proportional to the flow rate of the fluid. Specifically, when a fluid with a certain conductivity flows through the flow guide tube 231, it will cut the magnetic lines of force of the magnetic field formed by the coil 236, thereby generating an electromotive force E on the electrode 235. This electromotive force E is proportional to the product of the magnetic flux density B, the inner diameter d of the flow guide tube 231 and the average flow velocity v. The electromotive force E (flow signal) is detected by the electrode 235 and sent to the central control center 111 through a cable. After the central control center 111 amplifies and processes the flow signal, the fluid flow rate can be displayed. In particular, the flow guide tubes 231 of the two groups of electromagnetic sensor components 230 in the present invention have different diameters, and the diameter of the flow guide tube 231 is the same as the diameter of the corresponding outflow tube 114 and the shunt tube 112, so that they are respectively suitable for large flow detection and small flow detection. At the same time, in order to ensure the accuracy of the detection result, it is necessary to ensure that the liquid is in a full load state when flowing through the flow guide tube 231.

[0045] The working principle of the technical solution provided by the present invention is as follows: the fluid pipeline to be tested is connected to the pipe mouth of the flange pipe 170, and then the valve body of the fluid pipeline is opened to allow the fluid in the fluid pipeline to enter the flange pipe 170. At this time, the liquid level detector 171 in the flange pipe 170 can detect the liquid level of the fluid entering the flange pipe 170.

[0046] When the liquid level in flange pipe 170 does not reach the preset value of the liquid level detector 171, the central control center 111 sends an electrical signal to solenoid valve 210, so that solenoid valve 210 is closed and solenoid valve 220 is opened. At this time, the fluid entering the inner pipe 160 can enter the branch pipe 250 from the liquid separation port 163, and then enter the main branch pipe 240 through the check valve 260 on the branch pipe 250. During this process, the electromagnetic sensor component 230 can detect the flow of the fluid entering the branch pipe 250. Since the aperture of the branch pipe 250 and the liquid separation port 163 is much smaller than the aperture of the main branch pipe 240 and the liquid outlet 161, the liquid is in a full load state when entering the branch pipe 250, which is suitable for small flow fluid detection.

[0047] When the liquid level in the flange pipe 170 reaches the preset value of the liquid level detector 171, and after being buffered by the inner pipe 160, the liquid in the inner pipe 160 flows into the outflow pipe 114 through the liquid outlet 161, and impacts the feeler rod 125. Under the limiting effect of the elliptical groove 116, the feeler rod 125 drives the impacted ball 124 to rotate, thereby driving the circular plate 121, the base 126 and the arc-shaped top platform 130 to rotate. At this time, the angle sensor 134 can detect the rotation angle of the arc-shaped top platform 130. When the rotation angle of the arc-shaped top platform 130 reaches the preset value, the central control center The core 111 will transmit an electrical signal to the solenoid valve 1 210, so that the solenoid valve 1 210 opens and the solenoid valve 2 220 closes. At this time, the fluid entering the inner pipe 160 can enter the main branch pipe 240 from the liquid outlet 161. During this process, the electromagnetic sensor component 230 can detect the flow of the fluid entering the main branch pipe 240. Since the flow rate of the fluid is large, the liquid is in a full load state when entering the main branch pipe 240. It is suitable for large-flow fluid detection. At the same time, it can alleviate the hydraulic pressure inside the transportation pipeline to prevent accidents such as pipeline blockage and over-pressure damage.

[0048] If the liquid entering the flange pipe 170 is in a trapezoidal wave, that is, the liquid flow rate suddenly decreases after a large flow rate, when the liquid level in the flange pipe 170 does not reach the preset value of the liquid level detector 171, or the turning angle of the arc top platform 130 does not reach the preset value, at this time, the solenoid valve 1 210 is closed and the solenoid valve 2 220 is opened, and the liquid always enters the branch pipe 250 from the liquid separation port 163.
