摘　　要：通过对安徽省某输气管道1#阀室气液联动执行机构在各种极端工况(上下游站场或阀室发生爆炸、阀室本身泄漏、上下游线路截断阀误关断)下的研究,提出1#阀室气液联动执行机构的压降速率与持续时间的推荐值。The pneumatic-hydraulic actuator in 1 # valve station of one gas pipeline in Anhui Province is investigated under various extreme conditions, including explosion of upstream and downstream stations and valve stations,leakage of valve station, shut down of upstream ＆ downstream block valve station by mistake. The appropriate pressure drop rate setting value and duration time for pneumatic-hydraulic actuator are recommended in this study.
