摘　　要：介绍了一种不同于现有上装式球阀的新型超低温可在线拆装维修的球阀,为解决在线拆卸的实际需求,提出了一种新的解决方案。当前国内外常见的超低温上装式球阀,使用过程中如果出现泄漏只能是在线更换对应的零件,其更换过程非常繁琐且更换后阀门整体的密封性能无法当场得到验证,只能等到管线再次开车时才能确认。了解可在线拆装维修的球阀优化结构,降低了加工难度,节省了成本。成品不仅在线维修更方便,且更换零配件之后,可以当场检测其维修后的密封性能,为管线的停车检修节省了更多的时间。同时维修时操作的难度更低,可以完美解决了当前上装式球阀难拆难修的问题。This article introduces a new type of ultra-low temperature online disassembly and maintenance ball valve that is different from the existing top mounted ball valve.To address the practical needs of online disassembly,a new solution is proposed.The commonly used ultra-low temperature top mounted ball valves at home and abroad can only be replaced online if there is leakage during use.The replacement process is very cumbersome and the overall sealing performance of the valve after replacement cannot be verified on the spot.It can only be confirmed when the pipeline is restarted.The ball valve introduced in this article that can be disassembled and repaired online has optimized its structure,reduced processing difficulty,and saved costs.The finished product is not only more convenient for online maintenance,but also allows for on-site testing of its sealing performance after replacement of spare parts,saving more time for pipeline shutdown and maintenance.At the same time,the difficulty of operation during maintenance is lower,which can perfectly solve the current problem of difficult disassembly and repair of top mounted ball valves.
