摘要(Abstract)：

针对高温高压蒸汽调节阀在蒸汽加热熔盐储热系统中需承受高温、高压、高压差，且需频繁、高精度调节的设计制造难题，以某蒸汽加热熔盐储热示范工程为研究对象，结合高温高压蒸汽调节阀的实际应用需求，对其不同选型工况下的通流能力展开系统的计算与分析，提出在调节阀不同开度区间设计不同节流降压级数的技术方案。该方案有效实现了阀门在全工况下的良好适应性，能够精准匹配系统在不同运行阶段的调节需求，显著提升了调节精度。当上游蒸汽流速较低时，推荐采用蒸汽辅助雾化喷嘴，可以使减温水雾化颗粒更加细密，雾化效果更好，减少对管路的热冲击、热应力，保证了减温后设备的安全。梳理了高温高压蒸汽调节阀选型过程中的关键注意事项，可为后续同类蒸汽加热熔盐储热项目中的高温高压蒸汽调节阀选型和设计提供重要参考和借鉴。
