[Abstract]:Valve is the key equipment in power station to control and regulate the flow and pressure of transmission medium. It has an important influence on the normal operation of the power station, and is the equipment which can easily cause the hidden trouble of safety. All special valves in our country basically rely on imports. Therefore, it is of great practical significance to develop a digital valve design system which integrates data management, characteristic analysis and optimization design. In this paper, the method of valve data management, the technology of valve characteristic analysis based on knowledge, the technology of structure optimization based on characteristic analysis and the development technology of digital design system are studied. On this basis, a digital valve design system is developed. On the basis of analyzing the requirement of the system, the overall frame structure of the digital design system of power station valve is studied, the main work flow and function structure of the system are refined, the database design and development method of the system are studied. The database is established by SQL Server, and the data management of the system is realized by studying the connection technology of the database. This paper studies the multi-disciplinary characteristic analysis process of power station valve structure, such as static, thermal stress, vibration mode and so on, completes the compilation of the general characteristic analysis template of valve with invariant topology, and analyzes the interactive process of integrated information of ANSYS. The valve simulation analysis based on template is completed, and the information transmission and sharing in the simulation analysis process is realized. By means of mathematical statistical regression analysis, the mapping relationship between valve body structure parameters and its performance is studied, the mathematical model between structure parameters and performance is established, and the problem of valve structure optimization is studied. The valve structure optimization design oriented to characteristic analysis is realized. The digital design system of power plant valve is developed based on the current mainstream development technology. The whole process data management from design, simulation to final structure optimization is realized, and the design quality and design efficiency of the valve are improved.
