There are many factors that determine the reliability of magnetic flap valves; it can be said that every stage of the product’s production process is related to its quality and overall performance. So, what are the key factors that determine the reliability of magnetic flap valves? Before answering this question, let’s take a look at a few details: 1. The proper processing and assembly of the magnetic flaps, as well as the smoothness of the grooves in the guide rails and the presence of any burrs, all affect whether the flaps can move smoothly and whether they can accurately reflect the liquid level ； 2. When welding pipes and fittings, whether the welding current is appropriate and whether the welded area is fully penetrated also affects the safety of the product during use; poor control of dimensions can also impact whether the product can be installed properly. It is easy to see that, when the technical level is the same, the production process of the product can be considered the key factor determining the operational reliability of magnetic flap level gauges. To ensure product quality and the reliability of operations, Shenzhen Jiewei Automation Technology Co., Ltd. continuously improves its manufacturing processes, develops scientific and efficient production methods, and applies them in actual production. Specifically, the advantages of the magnetic flip-type level gauge in terms of production process are mainly reflected in the following aspects: First is the assembly process of the display panel. The display panel is the component used to indicate the liquid level; the magnetic flaps are placed in the grooves of the guides within the cavity, with equal spacing between each groove. Both ends of these grooves are sealed with plugs, and a glass panel covers the upper surface. The glass panel and the plugs are sealed together using glass adhesive. Shenzhen Jiwei Automation Technology Co., Ltd. has strict guidelines for operations during the assembly of display panels: 1) Keep the work surface clean. During operation, it is not allowed for debris or particles to fall into the mold cavity, and there must be no residual adhesive inside the cavity ； 2) Control the pushing force to prevent the sheet from warping. When pushing the guide rail with the flipped flag into the profile cavity, make sure to use appropriate force to avoid deformation of the flipped piece ； 3) Seal both ends of the panel. Ensure proper sealing at both ends of the display panel to prevent dust, sand, and moisture from entering inside ； 4) The sealant is applied in the appropriate amount and appears neat. When sealing the glass panel and the mold cavity, pay attention to using an appropriate amount of sealant to ensure a tight seal at the contact surface between the two components and a neat appearance. Secondly, there is the production process of magnetic flip switches. Magnetic flip switches are components used to indicate liquid levels; they contain a small magnetic rod, with their two outer surfaces painted in different colors (usually red and white). When subjected to the magnetic field generated by the magnetic float inside the measuring float, these flip switches rotate, and the change in color is used to indicate the liquid level. If the ends of the magnetic flap are not finely processed, with burrs, deformation, or an uneven and rough surface, it will increase the rotational resistance, resulting in inflexible flipping of the flap and an irregular appearance. To avoid such issues, Shenzhen Jiwei Automation Technology Co., Ltd. pays close attention to the details of the manufacturing process when producing magnetic flip plates. The products must meet a range of requirements: there must be no burrs on the end surfaces of the rotating parts, the surface finish must be smooth, the magnetic properties of the internal magnetic columns must be consistent, and the weight of the flip plates must also be appropriate – only then can they be shipped. Third is the manufacturing process of the magnetic float. The magnetic float moves up and down as the liquid level changes; the magnet inside the float is positioned right at the liquid surface, and through magnetic coupling it causes the outer flaps to turn, thereby indicating the liquid level. Shenzhen Jiwei Automation Technology Co., Ltd. adheres strictly to the requirements of the manufacturing process when producing floats: first, the welding of the outer tube of the float is carried out in such a way as to ensure thorough welding, thereby preventing leaks that might occur after the float has been in use for an extended period of time ； Secondly, the magnet must be placed in the correct position; strict weighting is required based on the principle of buoyancy and the corresponding densities, to ensure that the float accurately reflects the liquid level. Fourth is the welding process for the main pipes and process connection components. Flanges, as well as the pipes used for measuring and connecting to the process systems, are all joined together by welding. During welding, improper selection of the welding current or inadequate preparation of the weld joint’s groove can lead to poor welding quality, poor formation of the weld seam, incomplete penetration, and an increased risk of leaks. Therefore, the product must undergo hydrostatic testing to prevent leaks at the welds. In addition, Shenzhen Jiwei Automation Technology Co., Ltd. has also developed its own precision welding fixture platform, designed specifically for welding process connection flanges. This platform ensures the parallelism and flatness of the flange surfaces on both ends, thereby guaranteeing consistency across each batch of products. Fifth is the lining process for liner-type magnetic flap level gauges. Liner-type magnetic flap level gauges use a polytetrafluoroethylene tube lined inside a steel tube as an anti-corrosion layer, and the manufacturing process of this lining is crucial to the quality of the product. During the lining process in automated systems, the PTFE tube is first tightly fitted against the inner wall of the steel tube, thereby enabling the PTFE tube to have improved pressure resistance under the protection of the outer steel tube and extending its service life ； Secondly, an advanced new stretching and flanging process is adopted, which is easy to operate and features a reliable structure ； Furthermore, the process connection flange components are lined with F46 perfluoroethylene through die-casting; since F46 has better stress resilience than F4, it overcomes the problem of leakage that can occur due to the diameter mismatch between F4 and F4 pipes, thereby improving the sealing performance of the magnetic flap level gauge. Since the production process is the key factor determining the reliability of magnetic flap valves, Shenzhen Jiewei Automation Technology Co., Ltd. attaches great importance to the production process of its products. During the product development process, a series of production processes and testing methods were developed independently. Strict control is exercised over each stage of production, ensuring that the manufacturing of every product follows the established processes precisely. By strengthening quality control throughout the production process, it is ensured that the magnetic flap level gauges produced are reliable and have stable performance.
