The magnetic level gauge is a typical level gauge. There are many forms, according to the installation method, it is mainly divided into two forms: side and top. The top magnetic flip-board water level gauge is mainly suitable for measuring the liquid level of underground storage tanks, side holes, and containers with limited side installation space.
Generally speaking, the standard top disk water level gauge is composed of a buoy tube, a process connection flange, a protective belt, a buoy, and a liquid level marking component. It is usually suitable for measuring weakly corrosive liquids. However, due to the diversity of measuring media, a top magnetic flip-plate level gauge capable of measuring corrosive media is required. To this end, this article will specifically introduce the structure of the top magnetic flip-board water level gauge-the anti-corrosion-lined top flip-board water level gauge.For some containers with strong corrosive liquids, a corrosion-resistant magnetic half-plate water level gauge should be used.Generally speaking, the main difference between the anti-corrosion-lined magnetic reflector water level gauge and the standard magnetic reflector water level gauge is that the corrosion medium measured by the anti-corrosive PTFE plastic pipe lined with the main buoy tube is isolated from the steel pipe. Therefore, the measurement process is always in contact with the lining layer and the medium to achieve a better anti-corrosion effect.At present, many manufacturers are producing water level timers with anti-corrosion-lined top magnetic flip-boards, just by lining the sealing surface of the tetrafluoride pipe by stretching the connecting flange, and then tightening the thin Teflon gasket with the flange during installation. However, because the width of the stretched flange of the PTFE pipeline is inconsistent with the size of the sealing surface of the large flange connected during the top installation process, it is difficult to completely seal and there is a risk of leakage. Obviously, the production process has some defects, and the process of connecting the flange lining will not leak.Through careful analysis of the characteristics of the lining fluorine material, Huikeda selected the appropriate fluorine material, innovatively improved the structure of the magnetic half-plate water level gauge, and developed a high-quality magnetic half-plate water level gauge at the upper end of the lining, so that existing products can overcome the connection method The flange size is too large and the flange sealing surface is insufficient, which improves the corrosion resistance of the instrument and can meet the needs of measuring the water level of strong corrosive liquids in industrial production.Since the liner tower magnetic flip-board water level gauge went on the market, it has been recognized by many users, and applied for and obtained a national utility model patent for this technology.The utility model patent discloses the structure of the anti-corrosion-lined tower magnetic flap water level gauge. As shown in Figure 1, the cross-section of the connecting part of the connecting flange is used for the process of the top magnetic flipping plate level gauge. The serial number 200 in Figure 1 refers to the process of connecting the lining type top magnetic flip plate level gauge. The sealing surface lining anticorrosion layer of the flange is the core and difficult point of the top anticorrosive magnetic flip plate level gauge.Previously, the lining of the flange was achieved by stretching the detonator. The stretched edge does not become larger, which does not meet the anti-corrosion requirements of the flange lining. After the efforts and innovative design of automation engineers, a new type of anti-corrosion plastic-polyvinyl ethylene is selected and produced by a molding process. First of all, fluoroplastics need to be sintered for a long time at high temperatures and then molded to form an anti-corrosion layer on the upper surface of the flange. In this way, the formed anti-corrosion layer can not only meet the requirements of the flange sealing surface, but also has stronger adhesion of the lining, as shown in Figure 2.The upper and lower sides of the flange are lined with anti-corrosion layers. The upper lining anti-corrosion layer 410 is in contact and sealed with the PTFE flange on the buoy port flange of the upper body part, and the lower lining anti-corrosion layer matches the mounting flange of the container tank to form the entire continuous lining anti-corrosion layer to improve Improve the overall anti-corrosion performance of the instrument.The utility model patented technology has been successfully applied to the magnetic flap level gauge product, which greatly improves and improves the product performance of the magnetic flap level gauge, extends the product life, and ensures the stable operation of production, which has been well received by consumers.
