摘要: 大压差高压防喘振阀是高压空气压缩机系统中的关键部件，其设计需满足高压力、频繁启闭及密封性能要求。本文以1500 LB金属硬密封蝶阀为例，结合理论计算与实验验证，探讨其设计方法。理论部分涵盖材料选择、结构力学分析及密封性能计算；实验部分通过有限元仿真与物理测试验证评估合理性，最终确保阀门在1.5倍最大工作压差下的安全性与可靠性，表现出良好的力学性能与密封性。有限元分析为优化设计提供依据，物理实验验证了理论模型的准确性。

Abstract: The high-pressure anti surge valve with large pressure difference is a key component in the high-pressure air compressor system, and its design needs to meet the requirements of high pressure, frequent opening and closing, and sealing performance. This article takes the 1500 LB metal hard sealed butterfly valve as an example, and combines theoretical calculations and experimental verification to explore its design method. The theoretical part covers material selection, structural mechanics analysis, and sealing performance calculation; the experimental part verifies and evaluates the rationality through finite element simulation and physical testing, ultimately ensuring the safety and reliability of the valve under 1.5 times the maximum working pressure difference, demonstrating good mechanical performance and sealing. Finite element analysis provides a basis for optimizing design, and physical experiments verify the accuracy of the theoretical model.
