液化气体铁路罐车的紧急切断装置是保证液化气铁路罐车安全运行的重要装置。在正常情况下它是介质装卸的通道,而在紧急情况下又是一种灵敏可靠的截流止漏装置。液化气体铁路罐车在装卸过程中,当管路损坏、接头不严密时介质外溢造成污染、火灾及其他意外事故情况下,操作手压泵或远控阀,卸掉油压,紧急切断装置应在规定的时间内完全闭止、切断液源,防止事故的发生和扩大。笔者在液罐车安全附件检修实践中,发现不少有关该装置的问题。这些问题的存在危
The emergency shut-off device of liquefied gas railway tanker is an important device to ensure the safe operation of liquefied gas railway tanker. Under normal circumstances it is the media loading and unloading channels, and in emergencies is a sensitive and reliable closure device. Liquefied gas rail tanker in the loading and unloading process, when the pipeline is damaged, the joint is not tight medium overflow pollution, fire and other accidents, the operation of hand pump or remote control valve, remove the oil pressure, the emergency shut-off device should be Completely closed within the prescribed time, cut off the liquid source to prevent the occurrence and expansion of accidents. I tanker truck safety accessories overhaul practice and found a lot of problems on the device. These problems are dangerous
