| 摘 要： | 为了研究低温阀门的启闭密封的特性,对常温和低温下不同密封比压的密封结构进行了启闭密封特性试验,通过试验结果的分析得出了密封比压与泄漏率的关系曲线,并与H.T.洛马宁柯曲线进行了对比,得出了试验工况下密封比压计算修正系数,为低温密封结构设计提供依据。

| Abstract: | This paper studies the open-close sealing characteristics of cryogenic valves in different hermetical pressure.The leakage rate and hermetical pressure are recorded and analyzed.Compared with the theorized results of H.T.Pomatehko,experimental coefficients of hermetical pressure are simulated and can be used in cryogenic seal structure designing. |

| Keywords: | Cryogenic valve Open-close sealing Leakage rate Hermetical pressure |
