Description

Technical Field

[0001] The utility model relates to the technical field of flow meters, in particular to an assembled electromagnetic flow meter. Background Art

[0002] An electromagnetic flow meter is a flow measurement instrument that works based on Faraday's law of electromagnetic induction and is mainly used to measure the volume flow of conductive liquids. It consists of two parts, a sensor and a converter. The sensor includes a measuring tube and a pair of electrodes, and the converter is responsible for amplifying the induced electromotive force signal detected by the sensor and converting it into a standard signal for output.

[0003] The traditional electromagnetic flow meter is composed of a housing, a measuring conduit, a converter, etc. The measuring conduit is connected to the pipeline by screwing with multiple small parts. After the connection is completed, when the conductive liquid flows in the magnetic field, it will cut the magnetic force lines, thereby generating an induced electromotive force on the electrodes. This induced electromotive force is proportional to the flow rate of the liquid and the intensity of the magnetic field. By measuring the magnitude of the induced electromotive force, the flow rate of the liquid can be determined, and then the flow rate can be calculated.

[0004] The traditional electromagnetic flow meter usually uses a large number of small parts to cooperate for the installation and fixation of the electromagnetic flow meter, resulting in a time-consuming and laborious installation process, a slow installation speed, and a low installation efficiency. Therefore, an assembled electromagnetic flow meter is proposed to solve the above problems. Content of the Utility Model

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Referring to Figures 1 - 3 , an embodiment provided by the present invention: an assembled electromagnetic flowmeter, including a housing 1, a pipeline 2 is arranged on the side wall of the housing 1, an upper clamping block 3 is arranged between the housing 1 and the pipeline 2, a lower clamping block 4 is arranged on the lower surface of the upper clamping block 3, a first fixing block 5 is fixedly connected to the side wall of the lower clamping block 4, auxiliary components for sealing and preventing leakage are arranged inside both the upper clamping block 3 and the lower clamping block 4, an installation shell 1 is fixedly connected to the side wall of the upper clamping block 3, a fixing sleeve 8 is fixedly connected inside the installation shell 1, a first fixing column 9 is fixedly connected to the side wall of the fixing sleeve 8, a sliding clamping block 10 is slidably connected to the side wall of the first fixing column 9, the side wall of the sliding clamping block 10 is slidably connected inside the first fixing block 5, a pulling column 11 is slidably connected inside the fixing sleeve 8, a pulling handle 12 is fixedly connected to the upper surface of the pulling column 11, a fixing ring 14 is fixedly connected to the side wall of the pulling column 11, a rotating bar 15 is rotatably connected inside the fixing ring 14, one end of the rotating bar 15 is rotatably connected to the upper surface of the sliding clamping block 10, the auxiliary component includes a sealing gasket 6, the side walls of the sealing gasket 6 are fixedly connected inside both the upper clamping block 3 and the lower clamping block 4, the side wall of the sealing gasket 6 is attached to the side wall of the pipeline 2, a first spring 13 is sleeved on the side wall of the pulling column 11, one end of the first spring 13 is fixedly connected to the side wall of the fixing ring 14, and the other end of the first spring 13 is fixedly connected inside the installation shell 1;

[0034] During the operation of the device, when the electromagnetic flowmeter needs to be disassembled, first lift the pulling handle 12 upward. When the pulling handle 12 is lifted, it will pull the pulling column 11 upward. The upward movement of the pulling column 11 will further drive the fixing ring 14 upward. During this process, the fixing ring 14 will apply pressure to the first spring 13 and compress the first spring 13. At the same time, through the action of the rotating bar 15, the fixing ring 14 pulls the sliding clamping block 10 to slide toward the middle along the side wall of the first fixing column 9. During the sliding process of the sliding clamping block 10, it will enter the inside of the installation shell 1. When the sliding clamping block 10 successfully slides into the inside of the installation shell 1, the fixing effect between the originally fixed upper clamping block 3 and the lower clamping block 4 will be released. In this way, the connection between the housing 1 and the pipeline 2 will be broken, and finally the smooth disassembly of the electromagnetic flowmeter is realized. Through this quick installation and disassembly, when maintenance or replacement is required, the disassembly process of the electromagnetic flowmeter is simple, which helps to reduce the downtime during the production process. Due to the convenience of installation and disassembly, the electromagnetic flowmeter can more easily adapt to different working conditions and environments.

[0035] Reference Figures 4 - 5 Figures 4 - 5 , a connecting column 16 is fixedly connected inside the housing 1. The upper surface of the connecting column 16 is fixedly connected with a second mounting shell 17. A display 18 is arranged inside the second mounting shell 17. A rotating column 20 is rotatably connected inside the second mounting shell 17. A cover plate 19 is fixedly connected to the side wall of the rotating column 20. The side wall of the cover plate 19 is attached to the upper surface of the second mounting shell 17. A ratchet wheel 25 is fixedly connected to the side wall of the rotating column 20. A second fixing column 21 is fixedly connected to the side wall of the second mounting shell 17. A ratchet pawl 22 is rotatably connected to the side wall of the second fixing column 21. The ratchet pawl 22 is engaged with the ratchet wheel 25. A third fixing column 23 is fixedly connected to the side wall of the second mounting shell 17. A second spring 24 is arranged on the side wall of the third fixing column 23. One end of the second spring 24 is fixedly connected to the side wall of the third fixing column 23, and the other end of the second spring 24 is fixedly connected to the side wall of the ratchet pawl 22.

[0036] When it is necessary to view the display 18, the cover plate 19 can be manually toggled to rotate along a predetermined track. As the cover plate 19 is toggled, the rotating column 20 connected thereto will rotate accordingly. The rotation of the rotating column 20 will further drive the ratchet wheel 25 to start rotating. As the ratchet wheel 25 rotates, the second mounting shell 17 can be opened smoothly, facilitating the user to view the display 18. Due to the engagement relationship between the ratchet wheel 25 and the ratchet pawl 22, this design ensures that after the cover plate 19 is opened, the cover plate 19 will not slide down or close accidentally. This engagement mechanism provides stability and safety for the entire device, ensuring that when the user views the display 18, the cover plate 19 can remain in the open state and will not suddenly close due to external vibration or accidental touch, thereby protecting the display 18 from damage. By adding the second mounting shell 17, the physical damage and environmental factors on the display 18 can be reduced, which helps to extend the service life of the electromagnetic flowmeter. Through the cooperation of the cover plate 19 and the second mounting shell, the entry of dust and impurities into the internal structure of the flowmeter can be reduced, affecting the performance of its electronic components.

[0037] Working principle: When using this device, when it is necessary to disassemble the electromagnetic flowmeter, first pull up the lifting handle 12 to drive the pulling column 11 to move upward, thereby driving the fixing ring 14 to move upward, squeezing the first spring 13. At the same time, let the fixing ring 14 pull the sliding block 10 to slide towards the middle on the side wall of the first fixing column 9 through the rotating bar 15. When the sliding block 10 slides into the first mounting shell 7, at this time, the upper clamping block 3 and the lower clamping block 4 lose the fixing effect, and then it is opened, so that the housing 1 and the pipeline 2 are separated, completing the disassembly of the electromagnetic flowmeter. When it is necessary to view the display 18, by toggling the cover plate 19, the rotating column 20 rotates, so that the ratchet wheel 25 starts to rotate, and then the mounting shell 17 is opened for viewing the display 18. Due to the engagement relationship between the ratchet wheel 25 and the ratchet pawl 22, the opened cover plate 19 will not slide down easily.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
