Description

Technical Field

[0001] This utility model belongs to the field of electromagnetic flowmeter technology, specifically relating to an electromagnetic flowmeter that is easy to assemble and disassemble. Background Technology

[0002] Electromagnetic flow meters are instruments that use the principle of electromagnetic induction to measure the flow rate of conductive fluids based on the electromotive force generated when the fluid passes through an external magnetic field. Electromagnetic flow meters are now widely used in fields such as wastewater treatment, chemical industry, and pharmaceuticals to monitor the flow rate and volume of liquids in pipelines in real time.

[0003] Electromagnetic flow meters are typically installed between two pipe sections. Since some pipes are already laid and fixed, the spacing between the two pipe sections is fixed. This makes it difficult for the electromagnetic flow meter to fit tightly onto the pipe during installation, resulting in poor sealing after installation. Although setting a sealing ring can improve the sealing performance, the sealing ring protruding from the electromagnetic flow meter is difficult to move between the two pipe sections, increasing the difficulty of installation.

[0004] Therefore, an electromagnetic flowmeter that is easy to assemble and disassemble is proposed. Summary of the Invention

[0005] This invention provides an electromagnetic flowmeter that is easy to assemble and disassemble, with the aim of solving the problems mentioned above.

[0006] This utility model provides an easily detachable electromagnetic flowmeter, including a flowmeter housing 1 and a flowmeter housing 2 on one side. Electrodes are provided on the inner walls of both the flowmeter housing 1 and the flowmeter housing 2. A measuring conduit assembly is provided between the flowmeter housing 1 and the flowmeter housing 2. The measuring conduit assembly includes an outer conduit 1 and an outer conduit 2, with a bellows between the outer conduit 1 and the outer conduit 2. A fixing block 1 is provided on the outer wall of the outer conduit 1, and a fixing block 2 is provided on the outer wall of the outer conduit 2. A screw is provided on one side of the outer wall of the fixing block 1, and a nut is screwed onto the outer wall of the screw. A main ceramic liner is inserted into the inner side of the outer conduit 1, and an auxiliary ceramic liner is provided on the inner side of the outer conduit 2. An inner groove is provided at one end of each of the main ceramic liner and the auxiliary ceramic liner. A spring is provided on the inner wall of the inner groove, and a movable ceramic liner is provided on the inner side of the inner groove. A support rod is provided on the outer wall of the movable ceramic liner, and a ring is provided at one end of the support rod.

[0007] Furthermore, a limiting groove is formed on the inner side wall of the flowmeter housing 1 and the flowmeter housing 2 near the electrode. Horizontal half-flanges are provided on both sides of the flowmeter housing 1 and the flowmeter housing 2, and vertical half-flanges are provided on the outer side wall of the flowmeter housing 1 and the flowmeter housing 2. A display is installed on the vertical half-flange. The main ceramic lining is located between the flowmeter housing 1 and the flowmeter housing 2, and a retaining ring and an electrode groove are provided on the outer side wall of the main ceramic lining. The retaining ring is located on one side of the electrode groove.

[0008] Furthermore, one end of the first external conduit is provided with a docking flange, and one end of the second external conduit is provided with a pipe flange, and the docking flange and the horizontal half flange are fixedly connected.

[0009] Furthermore, the electrode and the electrode groove are matched and fitted together, and the outer wall of the electrode and the inner wall of the main ceramic lining are on the same circumferential surface.

[0010] By adopting the above technical solution, the flatness of the inner surface of the main ceramic lining is ensured, thereby guaranteeing the accuracy of flow measurement.

[0011] Furthermore, the screw passes through the second fixing block, and the ring sleeve is fitted on the outside of the screw;

[0012] By adopting the above technical solution, the distance between the first and second fixed blocks can be adjusted and fixed by the screw that passes through the second fixed block, and the screw can be used to support the support rod by the sleeve design.

[0013] Furthermore, the support rod passes through the bellows;

[0014] By adopting the above technical solution, the auxiliary ceramic lining can be supported by the support rod, ensuring the structural strength of the auxiliary ceramic lining and preventing bending deformation of the auxiliary ceramic lining under water pressure. The design of penetrating the corrugated pipe can prevent the corrugated pipe from affecting the support of the support rod during expansion and contraction.

[0015] Furthermore, the inner radii of the main ceramic liner and the auxiliary ceramic liner are the same;

[0016] By adopting the above technical solution, the water flow in the main ceramic lining and the auxiliary ceramic lining is stabilized, avoiding changes in the inner diameter that could affect the flow velocity and thus the accuracy of the measurement.

[0017] Furthermore, the limiting groove and the retaining ring are engaged.

[0018] By adopting the above technical solution, the limiting groove and the retaining ring can be engaged and limited, thereby limiting the main ceramic lining.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. This utility model uses an electromagnetic flow meter with an adjustable overall length, which can be easily installed and removed between two pipe sections and can also ensure the sealing after installation. The movable ceramic lining can keep the water flow velocity in the electromagnetic flow meter in a stable state, ensuring the measurement accuracy and protecting the bellows. The locking and supporting structure formed by the screw and support rod can support the auxiliary ceramic lining, ensuring the structural strength of the auxiliary ceramic lining and preventing bending and deformation of the auxiliary ceramic lining under water pressure.

[0021] 2. This utility model, through its detachable electromagnetic flow meter design, allows the electromagnetic flow meter to be disassembled into multiple units, and the worn lining inside can be replaced, thus extending the service life of the electromagnetic flow meter.

The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] Example 1

[0031] Reference Figure 1-3 This utility model embodiment proposes an electromagnetic flowmeter that is easy to assemble and disassemble, including a flowmeter housing 1 and a flowmeter housing 2 on one side. Electrodes 21 are provided on the inner sidewalls of both the flowmeter housing 1 and the flowmeter housing 2. A measuring conduit assembly 4 is provided between the flowmeter housing 1 and the flowmeter housing 2.

[0032] The measuring conduit assembly 4 includes an outer conduit 1 41 and an outer conduit 2 42. A bellows 43 is provided between the outer conduit 1 41 and the outer conduit 2 42. A fixing block 1 44 is provided on the outer wall of the outer conduit 1 41, and a fixing block 2 45 is provided on the outer wall of the outer conduit 2 42. A screw 46 is provided on one side of the outer wall of the fixing block 1 44, and a nut 47 is screwed onto the outer wall of the screw 46. A main ceramic liner 5 is inserted into the inner side of the outer conduit 1 41, and an auxiliary ceramic liner 51 is provided in the inner side of the outer conduit 2 42. The inner radii of the main ceramic liner 5 and the auxiliary ceramic liner 51 are the same, which makes the water flow in the main ceramic liner 5 and the auxiliary ceramic liner 51 stable and avoids changes in the inner diameter that would cause changes in flow velocity and affect the measurement accuracy. An inner groove 52 is provided at the opposite end of the main ceramic liner 5 and the auxiliary ceramic liner 51. The inner wall of the inner groove 52 is provided with A spring 53 is provided, and a movable ceramic liner 54 is provided on the inner side of the inner groove 52. A support rod 55 is provided on the outer wall of the movable ceramic liner 54. The support rod 55 passes through the bellows 43 and can support the auxiliary ceramic liner 51 to ensure the structural strength of the auxiliary ceramic liner 51 and prevent the auxiliary ceramic liner 51 from bending and deforming under water pressure. The design of passing through the bellows 43 can prevent the bellows 43 from affecting the support of the support rod 55 during the expansion and contraction deformation. A ring 56 is provided at one end of the support rod 55. A screw 46 passes through the second fixing block 45. The ring 56 is sleeved on the outside of the screw 46. The distance between the first fixing block 44 and the second fixing block 45 can be adjusted and fixed by the screw 46 passing through the second fixing block 45. The ring 56 can be sleeved to support the support rod 55.

[0033] Specifically, during the installation of the electromagnetic flowmeter, the overall length of the electromagnetic flowmeter is adjusted according to the distance between the two pipe sections. The expansion and contraction capability of the bellows 43 allows for adjustment of the distance between the outer conduit 1 41 and the outer conduit 2 42. As the relative positions of the outer conduit 1 41 and the outer conduit 2 42 change, the main ceramic lining 5 and the auxiliary ceramic lining 51 are displaced. Under the deformation of the spring 53, the movable ceramic lining 54 moves within the inner groove 52. The movable ceramic lining 54 remains within the outer conduit... The space between pipe 41 and outer conduit 42 is blocked, and the inner side of the corrugated pipe 43 is also blocked. The screw 46 moves through the fixing block 45. After the electromagnetic flow meter can be completely inserted into the space between the two pipe sections, the electromagnetic flow meter is connected and fixed to the pipe with bolts. After the installation and fixing of the electromagnetic flow meter is completed, the nut 47 is screwed onto the screw 46 and pressed against the fixing block 45 to achieve the fixing after the distance between the outer conduit 41 and the outer conduit 42 is adjusted.

Horizontal semi-flanges 23 are provided on both sides of both the flowmeter housing 1 and the flowmeter housing 2, and vertical semi-flanges 24 are provided on the outer sidewalls of both the flowmeter housing 1 and the flowmeter housing 2. A display 3 is mounted on the vertical semi-flanges 24. A main ceramic lining 5 is located between the flowmeter housing 1 and the flowmeter housing 2, and the main ceramic lining... A retaining ring 57 and an electrode groove 58 are provided on the outer side wall of the main ceramic lining 5. The retaining ring 57 is located on one side of the electrode groove 58. The electrode 21 and the electrode groove 58 are matched and fitted. The outer side wall of the electrode 21 and the inner side wall of the main ceramic lining 5 are on the same circumferential surface to ensure the flatness of the inner surface of the main ceramic lining 5, thereby ensuring the accuracy of flow measurement. The limiting groove 22 and the retaining ring 57 are engaged to achieve the limiting of the main ceramic lining 5. One end of the outer conduit 1 41 is provided with a docking flange 48, and one end of the outer conduit 2 42 is provided with a pipe flange 49. The docking flange 48 and the horizontal half flange 23 are fixedly connected.

[0036] Specifically, to facilitate the replacement of the main ceramic liner 5 and auxiliary ceramic liner 51 after prolonged use and wear, the horizontal half flange 23 and the docking flange 48 are disassembled and separated. The outer conduit 1 41 and the outer conduit 2 42 are then pulled out from the main ceramic liner 5. Then, the flow meter housing 1 and the flow meter housing 2 are disassembled and separated. At this point, the electromagnetic flow meter is divided into two parts, with the main ceramic liner 5 exposed. The main ceramic liner 5 can be directly replaced. After the main ceramic liner 5 is replaced, it can be reassembled.
