介绍了一种新型的液化气罐车用安全阀及其带压堵漏器的性能和工作原理。当安全阀发生泄漏时,带压堵漏器可方便快速地安装在安全阀上,达到迅速堵漏、防止事故蔓延扩大的目的。

A safety valve and its leak stopping device with pressure for liquefied gas tanker

A new kind of safety valve and its leak stopping device with pressure for liquefied gas tanker is introduced.Firstly it is made up of safety valve and its leak stopping with pressure,and the key components is designed in the tanker so it can reduce the leakage accident because of the outside force impact;Secondly the safety valve spring do not contact with the medium,so the medium brushing and erosion under the high stress for valve spring is avoided;Finally the safety valve and leak stopping device are separated usually,and when the leaking is occurred the leak stopping with pressure is installed quickly on the safety valve,so the leaking of valve is stopped quickly and the heavy accident is prevented.
