摘　　要：利用Solidworks建立旋启式抽汽止回阀的仿真分析模型,采用有限元仿真分析的方法验证高温、高压工况下,旋启式止回阀关键零部件强度是否满足设计要求,同时模拟蒸汽介质在阀门内部的流动情况,绘制阀瓣升力距和重力矩变化曲线,验证阀瓣是否可以开启至全行程,从而指导旋启式抽汽止回阀的设计与优化。Using Solidworks to establish a simulation analysis model for extraction check valves,using finite element simulation analysis to verify whether the strength of key components of extraction check valves meets the design requirements under high temperature and high pressure conditions.Simultaneously simulate the flow of steam medium inside the valve,draw the curve of valve disc lift distance and weight moment variation,verify whether the valve disc can be opened to the full stroke to guide the design and optimization of the extraction check valve.
