Description

Technical Field

[0001] This utility model relates to the field of high-temperature resistant rectangular electromagnetic flowmeter. Background Technology

[0002] An electromagnetic flowmeter is an instrument that uses the principle of electromagnetic induction to measure the flow rate of a conductive fluid based on the electromotive force induced when the fluid passes through an external magnetic field. The main components of an electromagnetic flowmeter are a magnetic circuit system, a measuring conduit, electrodes, a housing, a lining, and a converter.

[0003] Existing technology, such as the electromagnetic flowmeter disclosed in Chinese Publication No. CN202322929902.0, includes an electromagnetic flowmeter body, a rotation limiting ring, a rotation limiting ring convex ring, an electromagnetic flowmeter lower opening, an arc-shaped side baffle, an arc-shaped lower fitting plate, positioning posts, a sliding guide rod, a spring, and a circular connecting plate. The lower part of the electromagnetic flowmeter body has an electromagnetic flowmeter lower opening, and the arc-shaped lower fitting plate is adapted to the electromagnetic flowmeter lower opening and inserted into the electromagnetic flowmeter lower opening. The inner and outer diameters of the arc-shaped lower fitting plate are the same as the inner and outer diameters of the electromagnetic flowmeter body, and the outer side of the arc-shaped lower fitting plate is aligned with the outer side of the electromagnetic flowmeter body. The upper part of the arc-shaped lower fitting plate has multiple positioning posts, and the lower opening of the electromagnetic flowmeter has multiple positioning post slots. The positioning posts are adapted to the positioning post slots and inserted into the positioning post slots. The upper part of the electromagnetic flowmeter body has an electromagnetic flowmeter head, and the electromagnetic flowmeter body is connected to the arc-shaped side baffle, which is symmetrically arranged on the left and right sides of the electromagnetic flowmeter body.

[0004] In existing technologies, the overall structure is usually circular, which means that the display screen of the electromagnetic flow meter is usually located on the side of the device. During use, when the high temperature of the detection pipe and steam are discharged upward, the LCD screen will be affected by high temperature and water mist, which will reduce the life of the display screen over time. In addition, the existing device structure is not convenient to hold. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a high-temperature resistant rectangular electromagnetic flow meter to solve the technical problems of the display screen being easily damaged by high temperatures and the flow meter being inconvenient to grip.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature resistant rectangular electromagnetic flow meter, comprising a flow meter, the flow meter being rectangular in shape, a controller being installed at the top of the flow meter, an upper inclined surface and a lower inclined surface being connected to the outer wall of the flow meter, the upper inclined surface being located above the flow meter and the lower inclined surface being located below the flow meter, an LCD screen being installed inside the controller, and connectors being installed at both ends of the flow meter.

[0007] By adopting the above technical solution, the flow meter can be easily grasped and moved, and the LCD screen can be kept away from the pipe, thereby reducing heat damage to the LCD screen. The inclined surface can also guide the steam, reducing steam damage to the LCD screen.

[0008] The present invention is further configured such that buttons and indicator lights are installed on both sides of the top of the controller located on the LCD screen, and two sets of indicator lights are symmetrically arranged.

[0009] Preferably, the indicator light can highlight the operating status of the LCD screen, and the display screen can be adjusted via buttons.

[0010] The present invention is further configured such that the connector is located on the outside of the lower inclined surface, and the outer wall of the connector is provided with a threaded groove.

[0011] Preferably, it can be easily connected to external pipelines.

[0012] The present invention is further configured such that a signal connector is connected to the side of the flow meter, and the signal connector is located on the side of the upper inclined surface, with the upper inclined surface located directly above the connector.

[0013] Preferably, the flow meter can be connected to external control equipment.

[0014] In summary, the present invention has the following main advantages:

[0015] 1. The electromagnetic flowmeter of this utility model can be easily connected to the pipeline by holding it on the outside of the rectangular shell during use, making it easy to grip.

[0016] 2. This utility model, through the design of an upper inclined surface, a lower inclined surface, and an LCD screen located away from the connector, ensures that the LCD screen is kept away from the connector during use. This reduces the heat exposure of the LCD screen during the detection process. Furthermore, during use, external steam will flow upwards along the outside of the flow meter, and the lower inclined surface will guide the steam, causing it to move upwards from the outside of the LCD screen, thus reducing damage to the LCD screen.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] The embodiments of this utility model will be described below based on its overall structure.

[0024] Please see Figures 1 to 3 A high-temperature resistant rectangular electromagnetic flowmeter includes a flowmeter 1, which is rectangular in shape. A controller 2 is installed on the top of the flowmeter 1. An upper inclined surface 101 and a lower inclined surface 102 are connected to the outer wall of the flowmeter 1, with the upper inclined surface 101 located above the flowmeter 1 and the lower inclined surface 102 located below the flowmeter 1. An LCD screen 3 is installed inside the controller 2. Connectors 4 are installed at both ends of the flowmeter 1. Connectors 4 are located outside the lower inclined surface 102, and the outer wall of the connector 4 has a threaded groove. A signal connector 103 is connected to the side of the flowmeter 1, with the signal connector 103 located on the side of the upper inclined surface 101, which is directly above the connector 4.

[0025] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 The top of the controller 2 is equipped with buttons 201 and indicator lights 202 on both sides of the LCD screen 3. Two sets of indicator lights 202 are symmetrically arranged.

[0026] During use, the electromagnetic flowmeter first needs to be installed on the pipeline. During installation, the rectangular flowmeter 1 can be easily grasped by hand from the outside, improving the gripping effect. It is then fixedly connected to the pipeline through the connector 4, with the LCD screen 3 facing upwards. During use, the fluid passes through the connector 4 and flows through the flowmeter 1. At this time, the electronic components inside the flowmeter 1 detect the flow rate. During the detection process, the rectangular structure positions the LCD screen 3 away from the pipeline, thereby reducing temperature interference with the LCD screen 3. Steam will be generated at the pipeline connection and other equipment below. The steam flows upward and first encounters the lower slope 102. The steam will liquefy upon contact with the lower slope 102 and then flow downwards. The unliquefied steam will float upwards along the lower slope 102, thus moving away from the LCD screen 3 and reducing steam interference with the LCD screen 3.

[0027] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
