摘要
在分析现有气控元件密封结构及其特点的基础上,提出了一组高压空气控制元件用新型单密封结构和双密封结构以解决现有密封结构中的一些不足,新型双密封结构还能解决一些异常工况下密封结构失效导致直通的问题;通过新型高压密封结构的加工工艺以及选用材料的研究与试验,证明了新型高压密封结构具有良好的密封性与可靠性等优点.
Based on the analysis of typical seal structure of pressure control component,a group new type of single and double seal structure is presented.The new seal structure＇s material matching and manufacture techniques is researched.The result of experimentation shows that the new seal structure has good seal performance and reliability,and the double seal structure can solve some problem of full flux leakiness which is caused by seal structure＇s invalidation.
