摘要

针对核电站严苛环境下的风阀密封结构，为提高密封性能和耐久性，确保核电站安全稳定运行。本文对现有风阀密封结构进行理论分析，找出影响密封性能的关键因素。基于理论分析结果，设计并制作不同密封结构的实验样品。通过实验和数值模拟对比分析，确定最佳密封结构方案。优化后的风阀密封结构在密封性能、耐久性和抗腐蚀性能方面均得到了显著提升。实验结果表明，优化后的密封结构在高温、高压、高湿等严苛环境下，密封性能优于传统结构，且密封寿命延长。

Abstract

Aiming at the sealing structure of the air valve in the harsh environment of nuclear power plants, in order to improve the sealing performance and durability and ensure the safe and stable operation of nuclear power plants. This paper conducts a theoretical analysis of the existing sealing structure of air valves and identifies the key factors affecting the sealing performance. Based on the results of theoretical analysis, experimental samples with different sealing structures were designed and fabricated. Through comparative analysis of experiments and numerical simulations, the optimal sealing structure scheme is determined. The optimized sealing structure of the air valve has been significantly improved in terms of sealing performance, durability and corrosion resistance. The experimental results show that the optimized sealing structure has better sealing performance than the traditional structure in harsh environments such as high temperature, high pressure and high humidity, and the sealing life is prolonged.
