摘　　要：在油轮的货仓系统中,通常都装有PV阀(中文名字叫高速压力-真空阀),以便油轮在装卸过程中和营运过程中起到保护货仓的作用,以防止安全事故的发生。但在实际过程中,如果有货油进入该阀门或者连接管路后,使有可能使其失效。PV valves can be widely applied for cargo oil tankers in order to protect the tankers when cargo pumps run. However, sometimes they maybe lose the function when the cargo pumps run due to cargo oil came in the pipelines or the PV valves caused by the wobble of the vessel, vibration and so on.

关 键 词：油轮 PV阀 货仓 安全
