摘要
论述了航天发动机阀门中金属波纹管动密封零泄漏技术的密封原理。介绍了金属波纹管动密封的构成、加工、试验以及在航天阀门中低温、高压、高温工况下的应用。
The dynamic sealing of aerospace engine valve in high pressure,low or high temperature condition demand the zero leakage however metal bellows dynamic sealing can achieve.The paper presents the zero leakage metal bollows dynamic sealing technology（structure,Principle,processing,test.）in aerospace valve and its new application.
