摘要
针对特殊工况的阀杆填料密封中,环境温度和压力的变化、密封环的压实、工作期间的磨损引起的泄漏问题,根据密封原理,对阀杆填料密封和阀杆填料密封补偿的形式进行研究,提出了连续调整的方法,通过增加碟形弹簧补偿装置对阀杆填料密封进行了补偿,给出了碟形弹簧设计计算方法,为阀杆填料密封设计提供一定的参考。
As for the leakage caused by the changes in ambient temperature and pressure,Compaction of seal ring and w earing during the operation,aiming at the stem packing sealing in special services,based on sealing principle,the paper conducts research on the stem packing sealing and the compensation forms of the stem packing sealing,proposes the methods of continuous control,gives compensation for the stem packing sealing by adding butterfly springs compensation device,and gives design calculation methods for butterfly springs,provides particular reference for the stem packing sealing design.
