稳压器人孔楔形石墨密封结构设计与验证
Design and Verification Test of Wedge Graphite Seal Structure Used for Manway on Pressurizer
【摘要】 对适用于稳压器人孔密封的结构方案进行分析,研究密封垫材料的功能性参数,利用数值分析手段对密封结构进行初步分析。在上述基础上,开展了楔形石墨密封结构1:1热态性能考核验证试验。试验结果表明,该密封结构在经历100次冷热循环试验考核后无泄漏,拆装过程简便。热态试验验证了该型密封结构具有工程应用可行性。
【Abstract】 This paper analyzed the structure option and studied the function parameter of the seal material. Numerical analysis was used to analyze the seal structure. Based on all above, the one-to-one scale hot state verification test was carried out. The test results showed that there was no leakage after the wedge graphite seal structure experienced the 100 cold-hot cycling test. And also the results showed the seal structure was easy to install and dismounte. The engineering feasibility of the wedge graphite seal structure was verified.
