摘　　要：近年来,随着我国天然气工业的迅猛发展,涌现了一大批亟待开发的高含H2S气田。开展高含硫气田开发中的抗硫球阀密封结构的研究,解决目前抗硫球阀应用中,经常出现密封面腐蚀、泄露等问题,对确保高含硫气田开发地面系统的安全和平稳供气具有重要意义。以阀座密封面为研究对象,运用Pro/E对阀门密封件建模,并无缝连接到ANSYS中进行接触分析,分析不同阀座结构及材料的密封性能。研究结果显示:在材料屈服极限内,普通夹层阀座具有最大的连续接触压力,设计比压误差最小,为最优选型。In recent years, with rapid development of China＇s natural gas industry, a large number of untapped high H2S gas field has sprung up.A nd it has great significance for ground system safety and stable supply and solving the problems of sealing surface corrosion, leaks and other issues of the ball valve in hy- drogen sulfide environments.The research takes contact surface of valve seat as the research object, and an- alyzes the sealing performance among structures and materials.Using Pro/E to model the valve seal and seamlessly connect to ANSYS for contacting analysis.Within the material yield limit,the results af the study show that the ordinary sandwich valve seat with the maximum continuous contact pressure and the minimum error under the designed specific pressure is the optimization model.
