O型密封圈在氮气瓶主阀上的应用

Applied Research of O-Ring On Nitrogen Vessel's Main-valve

氮气瓶作为一种高压储气装置,氮气瓶上的主阀密封性能尤为关键,主阀引起的氮气瓶漏气故障较为常见,针对主阀用两种密封圈规格,分析密封原理,给出了最优密封圈选型,对该型主阀密封结构的应用和推广具有很大的指导意义。

Nitrogen vessel, as a kind of high pressure gas storage device, the main-valve＇s sealing performance is critical. The leakage caused by the main-valve failure is more common. According to two kinds of sealing ring specifications, the sealing principles of the main-valve are analyzed. The selection of optimal sealing ring is given. It has great directive significance to the application and popularization of this type of main-valve sealing structure.
