Books you can refer to are:
Valve design manual Yang; Handbook of valve design and calculation (second edition); Valve manufacturing technology; Manual of industrial valves, etc. Mechanical design manual is also necessary;
Of course, the functional thing is the foundation, that is, the structure, and the working principle must be obtained before the relevant design and improvement can be carried out;
First, structural design, CAD must be learned, and three-dimensional software must also be learned, including Solidworks, Peo/E, UG and Catia.
Second, strength analysis is necessary, so we should learn mathematics, mechanics and mechanical design well. Strength analysis can also be carried out with the help of software, and finite element analysis needs to be studied. The software includes Comosworks and Ansys.
Thirdly, there will be fluid aspects in valve design, such as flow channel design, flow capacity, flow characteristics research and so on. Study fluid mechanics, heat transfer, etc. , CFD software is Fluent, Ansys, CFX, Star-CD；; ;
In addition, materials and technology should also be learned.
You can also often go to technical forums to see:
1, technical forum on pumps and valves; 2, mechanical CAD forum, pipeline and pressure vessel plate; 3. China machinery industry, fluid machinery; 4. Haichuan Chemical Forum
Learn slowly. I also learned it step by step while using it. I came into contact with the valve in 2008. As long as I study hard, nothing is difficult.
