摘要
液态钠阀门作为核能、高温化工等领域的关键设备,其设计需应对高温、强腐蚀、高密封性等复杂工况。基于液态钠的物性特点,从材料选择、密封结构、热管理等方面系统分析了阀门设计的关键技术。通过对比不同材料的耐腐蚀性与高温稳定性,本文提出采用司太立合金与镍基合金的组合优化方法,并结合氩气幕墙技术构建多层次密封体系,解决了钠介质的高温泄漏难题。研究结果表明,合理的密封设计、热膨胀间隙控制与智能化监测是提升阀门可靠性与寿命的关键。本文为液态钠阀门的设计与工程应用提供了理论依据与实践参考。
As a key equipment in fields such as nuclear energy and high-temperature chemical engi-neering,the design of liquid sodium valves needs to cope with complex working conditions such as high temperature,strong corrosion,and high sealing performance.Based on the physical properties of liquid sodium,the key technologies for valve design were systematically analyzed from the aspects of material selection,sealing structure,and thermal management.By comparing the corrosion resistance and high temperature stability of different materials,this paper proposes a combination optimization method of Stellite alloy and nickel based alloy,and combines argon curtain wall technology to con-struct a multi-level sealing system,which solves the problem of high temperature leakage of sodium medium.The research results indicate that reasonable sealing design,thermal expansion gap control,and intelligent monitoring are key to improving valve reliability and lifespan.This article provides theo-retical basis and practical reference for the design and engineering application of liquid sodium valves.
