摘要
对永磁式机械地震截止阀、落球式机械地震截止阀以及天然气管道地震安全控制系统进行介绍。对汶川地震对天然气管道的破坏数据进行分析,总结管道破坏的原因,提出天然气管道的抗震对策。
The permanent mechanical seismic shut-off valve, ball drop mechanical seismic shut-off valve and seismic safety control system for natural gas pipeline are introduced. The data of earthquake damage for natural gas pipeline in the causes of pipeline damage Wenchuan are analyzed, are summarized, and the anti-earthquake countermeasures of gas pipeline are proposed.
