气液联动干线球阀作为川渝地区输气站场 ESD 系统的主要执行元件之一，是 ESD 系统的重要组成部分。球阀执行机构的合理设置不仅对气液联动干线球阀发挥干线切断功能起重要作用，还对保证 ESD 系统的安全功能具有重要影响。为此，通过分析川渝地区输气站场 ESD 系统中气液联动干线球阀执行机构存在的问题，提出了两种优化方案。结果表明，优化后的 ESD 系统满足独立设置原则和故障安全型原则。现场应用结果显示：①ESD 系统工作正常，能够发挥要求的安全功能；②ESD系统误动作率大大降低，起到了对输气站场的安全保护作用。

Pneumatic hydraulic ball valve,as an actuate element,is one of the main parts of ESD system in Sichuan-Chongqing gas transmission station.Reasonable set of pneumatic hydraulic ball valve as actuator not only plays an important role for cutting off gas supply,but also has an important influence on ensuring the safety function of ESD system.For these purpose,the existing problems of pneumatic hydraulic ball valve actuator in Sichuan-Chongqing gas transmission station were analyzed. And two optimization plans were put forward.The results show that ESD system can meet the princi-ple of independent setting and security after optimization improvement.Field applications show that:ESD system can work properly and play the required safety function;and the misoperation rate of ESD system reduces greatly and protect the safety of the gas station.
