[0050] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments.

[0052] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0053] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

[0054] See also Figures 1 to 5The embodiment of the present application provides a magnetic conductive component 100, which is installed on a measuring catheter 300. An induction electrode 400 is installed on both sides of the measuring catheter 300. The magnetic conductive component 100 includes a magnetic core 30, a coil winding 20 and two magnetic conductive sheets 10. The two magnetic conductive sheets 10 are connected to the magnetic core 30. The two magnetic conductive sheets 10 are arranged at intervals. The coil winding 20 is wound around the magnetic core 30 to form a magnetic field between the two magnetic conductive sheets 10. The measuring catheter 300 is passed between the two magnetic conductive sheets 10. The number of the coil winding 20 is one. The coil winding 20 and one of the induction electrodes 400 are arranged on the same side relative to the measuring catheter 300.

[0055] It can be understood that the coil winding 20 is wound around the outer circumference of the magnetic core 30, and the coil winding 20 can be connected to a power supply. The coil winding 20 is energized to generate a magnetic field in the magnetic core 30, and the magnetic field is transmitted to the magnetic conductive sheet 10 through the magnetic core 30, thereby forming a uniform and concentrated magnetic field between the two magnetic conductive sheets 10.

[0056] The coil winding 20 of the present application generates magnetic flux in the magnetic core 30, and forms a magnetic field between the two magnetic conductive sheets 10 through the magnetic core 30. Since the magnetic field strength of the magnetic core 30 is strong, coupled with the magnetic conductive effect of the magnetic conductive sheets 10, the utilization efficiency of the magnetic field can be improved and the magnetic field strength can be guaranteed. Therefore, the present application only needs to set up one coil assembly 20, which can reduce labor costs and material costs, simplify the production process, and thus improve producibility.

[0057] Preferably, the magnetic conductive sheet 10 includes a magnetic conductive plate 11 and a connecting sheet 12 connected to each other, the two connecting sheets 12 of the two magnetic conductive sheets 10 are respectively connected to the two ends of the magnetic core 30, the connecting sheet 12 includes a first sheet body 121 and a second sheet body 122 connected to each other, the extension direction of the first sheet body 121 and the extension direction of the second sheet body 122 are set at a first angle, and the first angle is an obtuse angle.

[0058] It can be understood that the measuring conduit 300 of the electromagnetic flowmeter will be inserted between the two magnetic conductive plates 11, and the sensing electrode 400 will be installed on the side wall of the measuring conduit 300 between the two magnetic conductive plates 11, so the extension direction of the first sheet 121 and the extension direction of the second sheet 122 are set at an angle, which is equivalent to the second sheet 122 being deflected relative to the first sheet 121, so that the installation position of the sensing electrode 400 can be avoided, thereby reducing the size of the electromagnetic flowmeter. If the deflection angle is not set, in order to avoid the sensing electrode 400, the length of the connecting sheet 12 must be increased, resulting in a larger lateral size of the electromagnetic flowmeter, and there is no position for installation in some occasions, thereby reducing the adaptability of the electromagnetic flowmeter. In addition, the second sheet 122 is deflected relative to the first sheet 121, so that the magnetic conductive plate 11 and the magnetic core 30 are connected at the shortest distance, reducing the magnetic circuit and reducing the magnetic circuit loss, thereby obtaining a stable and reliable magnetic field. Optionally, the first angle ranges from 110° to 160°.

[0059] In some embodiments, the magnetic conductive sheet 10 includes a plurality of sheets, and the plurality of sheets are stacked in sequence to form the magnetic conductive sheet 10 .

[0060] In some embodiments, the magnetic conductive component 100 further includes a housing 40, the housing 40 includes an upper cover 41 and a base 42 that cover each other, the magnetic conductive sheet 10 is sandwiched between the upper cover 41 and the base 42, and the upper cover 41 and the base 42 are an integrally welded structure or a snap-on connection structure. The upper cover 41 and the base 42 are an integrally welded structure, which can ensure the connection strength between the upper cover 41 and the base 42, or the upper cover 41 and the base 42 can also be connected by a snap-on connection for easy disassembly. In other possible embodiments, the upper cover 41 and the base 42 can also be a glue bonding structure, that is, the upper cover 41 and the base 42 are bonded by glue.

[0061] Specifically, the upper cover 41 and the base 42 are ultrasonic integrated welded structures. The upper cover 41 and the base 42 of the present application are welded into an integrated structure through an ultrasonic welding process, which can avoid the need to set up a fixing tool for the magnetic sheet 10 and a clamping tool for the magnetic core 30, and can simplify the installation process of the magnetic conductive component 100, effectively saving the cost of manual assembly. In addition, the present application can use ultrasonic welding equipment for welding to achieve automated operation, reduce manual intervention, and is beneficial to improving the consistency and stability of the final product, thereby improving the measurement accuracy of the electromagnetic flowmeter.

[0062] Moreover, the ultrasonic welding process is used to connect the upper cover 41 and the base 42, which is more energy-saving and environmentally friendly. Since ultrasonic welding does not require the use of traditional welding materials, such as flux, soldering agent or gas, it reduces environmental pollution and energy consumption, and the ultrasonic welding speed is fast, which greatly improves the production efficiency compared with the traditional welding method. Ultrasonic welding can also achieve seamless welding, with high welding point strength, good sealing, not easy to deform, crack or flanging, and no sparks during the welding process. It is suitable for occasions that require strict control of sparks. The surface after welding is well formed, without scratches and flux residues, and the welding point is beautiful, which improves the overall aesthetics of the product.

[0063] Preferably, the two magnetic conductive plates 11 of the two magnetic conductive sheets 10 are parallel to each other, and the extension direction of the magnetic core 30 is perpendicular to the plate surface of the magnetic conductive plate 11. The two parallel magnetic conductive plates 11 can concentrate the magnetic field and guide the uniform distribution of the magnetic field, so that the magnetic field strength is highly consistent between the two magnetic conductive plates 11, thereby reducing the leakage of magnetic flux, preventing the magnetic field from diffusing to irrelevant areas, and improving the utilization efficiency of the magnetic field to achieve a more uniform magnetic field distribution.

[0064] In some embodiments, the first sheet 121 is connected to the magnetic conductive plate 11, the first sheet 121 is connected to the side of the magnetic conductive plate 11 facing away from the other magnetic conductive plate 11, the first sheet 121 and the magnetic conductive plate 11 are perpendicular to each other, and the second sheet 122 is connected to the magnetic core 30. It can be understood that the first sheet 121 and the second sheet 122 are both sheet structures, specifically, the bottom edge of the first sheet 121 is connected to the magnetic conductive plate 11, and the bottom edge of the first sheet 121 is connected to the edge of the magnetic conductive plate 11, the side edge of the first sheet 121 is connected to the second sheet 122, the first sheet 121 is arranged in the vertical direction, the plate surface of the magnetic conductive plate 11 is arranged in the horizontal direction, and the first sheet 121 is perpendicular to the magnetic conductive plate 11, so that the magnetic field can be better guided through the two magnetic conductive plates 11, and the magnetic leakage of the magnetic field can be reduced, thereby improving the uniformity of the magnetic field between the two magnetic conductive plates 11.

[0065] In some embodiments, the connecting sheet 12 includes a first sheet 123 and a second sheet 124 stacked on the first sheet 123. The first sheet 123 and the magnetic conductive plate 11 are an integrally formed structure, and the magnetic core 30 is sandwiched between the first sheet 123 and the second sheet 124. Therefore, the stability of the connection between the magnetic core 30 and the first sheet 123 and the second sheet 124 can be improved.

[0066] In the present application, the magnetic conductive sheet 10 is a pure iron piece, a ferrite piece, a silicon steel piece, a plasma material piece or a copper-nickel-zinc alloy body piece, that is, the magnetic conductive sheet 10 is made of a pure iron material, a ferrite material, a silicon steel material, a plasma material or a copper-nickel-zinc alloy body material. Pure iron and ferrite are low magnetic permeability materials. Ferrite is a compound composed of iron (Fe) and oxygen (O) elements. Ferrite has magnetism and belongs to a magnetic material. The coercive force of pure iron is relatively high, while the coercive force of ferrite is relatively low, and the saturation magnetic induction intensity is also relatively low.

[0067] Silicon steel is easy to process, cut and shape, and can be made into parts and equipment of various shapes and sizes. Silicon steel has low iron loss, which means that it will not generate too much eddy current in the alternating magnetic field and cause energy loss, which enables silicon steel to better control energy loss and improve efficiency. In addition, silicon steel has high magnetic permeability, which means that it can better guide magnetic flux in the magnetic field and improve transmission efficiency.

[0068] In the present application, the magnetic core 30 is a Permalloy piece, a microcrystalline material piece, an ultramicrocrystalline material piece, a plasma material piece or a copper-nickel-zinc alloy body piece. In addition, the magnetic core 30 can be made of a multi-layer or single-layer magnetic conductive material. In the present application, the upper cover 41 and the base 42 are made of plastic material.

[0069] Further, the upper cover 41 includes two first shells 411 spaced apart from each other, one end of the two first shells 411 is connected to each other, the base 42 includes two second shells 421 spaced apart from each other, one end of the two second shells 421 is connected to each other, the two first shells 411 correspond to the two second shells 421 one by one, and the connecting piece 12 is sandwiched between the first shell 411 and the second shell 421. It can be understood that the shapes of the first shell 411 and the second shell 421 can be adapted to the shape of the connecting piece 12. The base 42 also includes a bending portion 422 protruding from the plate surface of the second shell 421, and the bending portion 422 is provided with a slot 4221. The magnetic conductive plate 11 extends into the slot 4221 and exposes the slot of the slot 4221, so that the two magnetic conductive plates 11 can face each other.

[0070] In some embodiments, see Figure 4 , the edge of the upper cover 41 is provided with a buckle 412, and the edge of the base 42 is correspondingly provided with a buckle position 423, and the buckle 412 is buckled and fixed with the buckle position 423, thereby realizing the connection between the upper cover 41 and the base 42, making the assembly of the magnetic conductive component more stable. It can be understood that the number of buckles 412 can be set to multiple, and accordingly, the number of buckles 423 can also be set to multiple, and the four sides of the upper cover 41 can be provided with buckles 412, and the four sides of the base 42 can be provided with buckles 423.

[0071] See also Figure 5The present application also proposes an electromagnetic flowmeter, which includes a magnetic conductive component 100. The specific structure of the magnetic conductive component 100 refers to the above embodiment. Since the electromagnetic flowmeter adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0072] The electromagnetic flowmeter further comprises a fixing frame 200 and a measuring conduit 300 . The fixing frame 200 is sleeved on the measuring conduit 300 . The magnetic conductive component 100 is installed on the fixing frame 200 . The measuring conduit 300 is passed between two magnetic conductive sheets 10 .

[0073] It can be understood that the electromagnetic flowmeter further includes two sensing electrodes 400 , which are symmetrical about the central axis of the measuring conduit 300 , face each other, and the line between the two sensing electrodes 400 is perpendicular to the magnetic field direction between the two magnetic conductive plates 11 .

[0074] To sum up, the coil winding 20 of the present application generates magnetic flux in the magnetic core 30, and forms a magnetic field between the two magnetic conductive sheets 10 through the magnetic core 30. Since the magnetic field strength of the magnetic core 30 is strong, coupled with the magnetic conductive effect of the magnetic conductive sheets 10, the utilization efficiency of the magnetic field can be improved and the magnetic field strength can be guaranteed. Therefore, the present application only needs to set up one coil assembly 20, which can reduce labor costs and material costs, simplify the production process, and thus improve producibility.
