Problems solved by technology

[0002] At present, the manufacturing technology of the domestic electro-hydraulic servo valve industry is still at a relatively backward stage, especially the relatively high-end servo valves are difficult to meet the design requirements in assembly, including the installation of magnetic steel, which is difficult to achieve a symmetrical effect. The installation of steel has the following disadvantages: 1. The alignment of the magnetic steel cannot be guaranteed; 2. The magnetic steel itself is easily broken during the installation process, which affects performance; 3. The magnetic steel has strong magnetism, and the gap cannot be precisely controlled during installation; The above problems can be solved by using the plug, and the manufacturing cost can be greatly reduced
