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。
The structure scheme applied to the manhole seal of the regulator is analyzed, the functional parameters of the gasket material are studied, and the seal structure is analyzed by means of numerical analysis. On the basis of the above, carried out a wedge graphite seal structure 1: 1 thermal performance verification test. The test results show that the sealing structure has no leakage after 100 cycles of thermal and thermal cycling tests, and the disassembly and assembly process is simple and convenient. The thermal test verified the feasibility of this type of seal structure for engineering application.
