摘要
金属密封三偏心球阀是一种新产品,应用于高温高压及工艺介质要求较苛刻的工况,目前国内有的阀门制造厂已研制成功。阐述了该类阀门的结构特点、密封原理(包括普通球阀、双偏心球阀及三偏心球阀),以及3种阀门的性能对比,三偏心球阀的优点、其设计采用有限元分析,对阀体的强度和刚度、阀座、密封环的接触应力和刚度、阀杆的强度和刚度进行了分析,并介绍了密封圈和阀座密封面的加工和此种阀门的应用工况。
This article introduces the functions of triple offset metal to metal sealing ball valve and briefly describes its structure characteristics,the sealing principles of concentric ball valve,bi-offset ball valve and triple offset ball valve,the performance comparison between concentric ball valve and triple offset ball valve,and the advantages,design and application of triple offset ball valve.
