Description

Technical Field

[0001] This utility model relates to the field of liquid level gauge technology, and in particular to an explosion-proof magnetic liquid level gauge. Background Technology

[0002] A magnetic level gauge is a commonly used liquid level measuring device that uses the principle of magnetism to detect and monitor the position of a liquid surface. A magnetic level gauge typically consists of two parts: a magnetic float and a magnetic sensor. The magnetic float transmits liquid level information by floating on the liquid surface.

[0003] Existing magnetic level gauges often experience high pressure at the connection point, and prolonged use in high-pressure environments can weaken these connections. When the tank pressure becomes abnormal, internal liquid leakage can occur, potentially leading to an explosion if the liquid is flammable. Furthermore, magnetic level gauges are generally large, making internal maintenance complex. Maintenance and replacement require draining the liquid from the tank before disassembling the gauge. To address these technical problems, this application proposes an explosion-proof magnetic level gauge. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an explosion-proof magnetic level gauge. This magnetic level gauge integrates pressure safety protection functions. When the pressure inside the tank exceeds the limit, the top warning device will immediately sound an alarm, and the operator can quickly drive the piston assembly to cut off the connecting pipe, thus preventing the risk of leakage and explosion, while also supporting disassembly and maintenance under pressure.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An explosion-proof magnetic level gauge includes a measuring plate, a measuring tube disposed on the rear side of the measuring plate, a flip-up indicator disposed on the front side of the measuring plate, a warning assembly connecting the top of the measuring tube to a warning device, a connecting rope fixedly connected to the inner wall of the measuring tube, a magnetic component slidably connected to the outer wall of the connecting rope, a float fixedly connected to the bottom of the magnetic component, a corrugated compensator fixedly connected to the top and bottom of the measuring tube, a connecting tube one disposed at the end of the corrugated compensator, a connecting tube three disposed at the end of the connecting tube one, a connecting tube two connected to the inner wall of the connecting tube three via a piston assembly, and connecting nozzles fixedly connected to the outer walls of both the connecting tube two and the connecting tube three.

[0007] Furthermore, the warning assembly includes a squeezing block slidably connected to the top of the measuring tube, a measuring rod fixedly connected to the top of the squeezing block, a spring sleeved on the outer wall of the measuring rod, and the top of the measuring rod connected to the warning device.

[0009] Furthermore, the piston assembly includes a limiting block fixedly connected to the inner wall of the connecting pipe three, a piston head slidably connected to the inner wall of the limiting block, a spring one sleeved on the outer wall of the piston head, a sealing ring provided on the outer wall of the piston head end, and the outer wall of the sealing ring fixedly connected to the connecting pipe two.

[0010] Furthermore, the inner wall of the connecting pipe is provided with a sliding groove, the outer wall of the connecting pipe is fixedly connected with a handle, the outer wall of the sliding groove is slidably connected with a slider, and the end of the slider is fixedly connected to the piston head.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-2 An embodiment of this utility model provides an explosion-proof magnetic level gauge, comprising a measuring plate 1, a measuring tube 2 disposed on the rear side of the measuring plate 1, a flip-plate indicator 3 disposed on the front side of the measuring plate 1, the top of the measuring tube 2 being connected to an alarm 4 via an alarm assembly, a connecting rope 21 being fixedly connected to the inner wall of the measuring tube 2, a magnetic component 20 being slidably connected to the outer wall of the connecting rope 21, a float 19 being fixedly connected to the bottom of the magnetic component 20, a corrugated compensator 5 being fixedly connected to the top and bottom of the measuring tube 2, a connecting tube 6 being disposed at the end of the corrugated compensator 5, a connecting tube 3 15 being disposed at the end of the connecting tube 6, the inner wall of the connecting tube 3 15 being connected to the connecting tube 2 11 via a piston assembly, and connecting nozzles 9 being fixedly connected to the outer walls of both the connecting tube 2 11 and the connecting tube 3 15.

[0025] Specifically, by installing the connecting pipes on the upper and lower outer walls of the measuring tube 2 to the connection point of the tank, the liquid in the tank enters through the bottom connecting pipe 2 11, then through the connecting pipe 3 15 and the piston assembly on the inner wall, and through the connecting pipe 1 6 and the corrugated compensator 5 into the measuring tube 2. The buoyancy of the liquid pushes the float 19 to float upward, and then the float 19 drives the magnetic component 20 to rise and fall on the connecting rope 21, thereby causing the flip indicator 3 in the measuring plate 1 to flip, thus providing feedback on the liquid level in the tank. When the pressure is too high, the corrugated compensator 5 will deform due to the pressure to reduce the pressure at the connecting pipe. At the same time, the magnetic block will be squeezed by the pressure to trigger the alarm 4 to sound an alarm. The alarm 4 is an audible and visual alarm. At the same time, the operator can cut off the pipeline of the connecting pipe by operating the piston assembly to prevent an explosion.

[0026] Reference Figures 2-3 The warning component includes a squeezing block 22 slidably connected to the top of the measuring tube 2, a measuring rod 24 fixedly connected to the top of the squeezing block 22, a spring 23 sleeved on the outer wall of the measuring rod 24, the top of the measuring rod 24 connected to the warning device 4, one end of the spring 23 connected to the squeezing block 22, the other end of the spring 23 connected to the measuring tube 2, and the top outer wall of the measuring tube 2 connected to the warning device 4. The squeezing block 22 is squeezed by the top of the magnetic component 20, which causes the squeezing block 22 to move the measuring rod 24 upward, thereby triggering the warning device 4. When the pressure is normal, the spring 23 will reset the squeezing block 22 by its elastic force.

[0027] The piston assembly includes a limiting block 18 fixedly connected to the inner wall of connecting pipe 15, a piston head 13 slidably connected to the inner wall of the limiting block 18, a spring 17 sleeved on the outer wall of the piston head 13, a sealing ring 12 provided on the outer wall of the end of the piston head 13, the outer wall of the sealing ring 12 being fixedly connected to connecting pipe 11, a sliding groove 16 formed in the inner wall of connecting pipe 15, a handle 7 fixedly connected to the outer wall of connecting pipe 15, a slider 14 slidably connected to the outer wall of the sliding groove 16, the end of the slider 14 being fixedly connected to the piston head 13, and the spring 17... One end is connected to the piston head 13, and the other end of the spring 17 is connected to the limiting block 18. By rotating the handle 7, the connecting pipe 3 15 is rotated, and then the sliding groove 16 on the inner wall of the connecting pipe 3 15 drives the slider 14 on the outer wall of the piston head 13 to slide, so that the end of the piston head 13 moves on the inner wall of the limiting block 18. The limiting block 18 has multiple water holes for medium flow, so that the piston head 13 blocks the sealing ring 12. The spring force of the spring 17 squeezes the piston head 13, which makes it easier for the operator to rotate the handle 7.

[0028] The outer walls of connecting pipe 1 (6), connecting pipe 2 (11), and connecting pipe 3 (15) are all equipped with flanges 8. The outer wall of connecting pipe 3 (15) is rotatably connected to flange 8. The flange 8 of connecting pipe 1 (6) is used to connect to the tank body. Connecting pipe 2 (11) and connecting pipe 3 (15) are connected through flange 8. Connecting pipe 2 (11) and connecting pipe 3 (15) are rotatably connected to remove connecting pipe 1 (6) after the piston is closed. The outer wall of measuring pipe 2 is equipped with multiple fasteners 10. The fasteners 10 are fixed to the rear side of measuring plate 1 by bolts. Measuring pipe 2 is installed on the rear side of measuring plate 1 through the fasteners 10.

[0029] Working principle: By installing the connecting pipes on the upper and lower outer walls of the measuring tube 2 to the connection point of the tank, the liquid in the tank enters through the bottom connecting pipe 2 11, then through the connecting pipe 3 15, and through the connecting pipe 1 6 and the corrugated compensator 5 into the measuring tube 2. The buoyancy of the liquid pushes the float 19 upward, which in turn drives the magnetic component 20 to rise and fall on the connecting rope 21, thereby causing the flip indicator 3 in the measuring plate 1 to flip, thus providing feedback on the liquid level in the tank. When the pressure is too high, the corrugated compensator 5 will expand and contract due to the pressure, reducing the pressure at the connecting pipe. At the same time, the pressure will push the float 19 and the magnetic component 20 upward, squeezing the squeezing block 22 through the top of the magnetic component 20. The squeezing block 22 drives the measuring rod 24 to move upward, thereby triggering the alarm 4. At the same time, the operator rotates the handle 7 to rotate the connecting pipe 15, which in turn drives the slider 14 on the outer wall of the piston head 13 to slide through the groove 16 on the inner wall of the connecting pipe 15. This causes the end of the piston head 13 to move on the inner wall of the limiting block 18, blocking the sealing ring 12 and cutting off the pipeline. The operator then reports the abnormal situation of the tank. When the pressure and water level are normal, the magnetic level gauge can be disassembled for inspection or replacement by removing the flange 8 of the connecting pipe 11 and the connecting pipe 15. After reinstallation, the handle 7 is rotated in the opposite direction to restore the pipeline.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
