摘要 安全阀依靠阀芯与阀座间的紧密贴合实现对流体介质的密封。阀芯与导向孔之间的配合间隙易使阀芯产生偏转, 进而导致密封配合界面出现不能消除的间隙, 致使阀门工作异常。该文基于ABAQUS软件, 对阀芯偏转工况下的密封界面进行了力学分析, 研究了阀芯偏转角度与阀门密封失效之间的关系, 通过提取仿真计算结果, 确定了该型阀门在常温与超低温工况下阀芯在保证密封性能的前提下允许的最大偏转角度。从阀芯偏转对阀门密封性能影响的角度, 提出了一套完整的仿真计算方法, 为阀门导向配合的公差设计和密封机构的尺寸设计提供了理论基础和参考。

Abstract:The sealing performance of safety valves relies on a tight fit between the spool and the seat. To avoid jamming, a larger fitting clearance is designed for spool guidance, which makes the spool deflection excessive, leading to a gap in the sealing interface and affecting the sealing performance. Based on ABAQUS, this paper conducts a mechanical analysis of the sealing interface under the conditions of spool deflection and studies the relationships between the spool deflection angles and sealing failure. By analyzing the simulation results, the maximum deflection angles of the spool are determined under the premise of ensuring the sealing performance at different operating temperatures. A complete simulation calculation method is proposed for the study field of valve sealing. The results provide a theoretical basis and reference for the design of fitting clearance and sealing part size of the valve.
