摘　　要：高温工况下特种阀门的设计与应用是确保高温高压设备安全稳定运行的关键技术之一。由于传统设计方法在高温工况下性能预测的不足,本文提出一种基于有限元分析的阀门优化设计方法。通过ANSYS软件对某型高温截止阀进行热-结构耦合分析,优化了阀体几何形状及密封面材料分布,显著降低了热应力集中。仿真结果表明,优化后阀门的最大热应力下降,密封面变形量减少,有效提升了耐高温性能与密封可靠性。本研究为高温阀门的创新设计提供了理论依据与工程实践参考。The design and application of special valves under high temperature conditions is one of the key technologies to ensure the safe and stable operation of high temperature and high pressure equipment.Due to the insufficient performance prediction of traditional design methods under high temperature conditions,a valve optimization design method based on finite element analysis is proposed.By using ANSYS software to perform thermal structural coupling analysis on a certain type of high-temperature globe valve,the geometric shape of the valve body and the distribution of sealing surface materials were optimized,significantly reducing thermal stress concentration.The simulation results show that the maximum thermal stress of the optimized valve decreases,the deformation of the sealing surface is reduced,and the high temperature resistance and sealing reliability are effectively improved.This study provides theoretical basis and engineering practice reference for the innovative design of high-temperature valves.
