公安部天津消防研究所研发了一种车载LNG泄漏自封堵装置“储罐管线附件泄漏应急处置装置”。该装置可广泛应用于LNG槽罐车。当车载LNG储罐、气瓶阀门或管件附件发生泄漏时,可通过翻转罐体,依靠阀芯自重将阀芯密封面与阀座密封面压紧,通过阀芯自身重力和内部介质压力的双作用,实现危险化学品储罐内设置的 Tianjin Fire Research Institute of the Ministry of Public Security has developed a self-contained vehicle LNG leakage sealing device “tank line attachment leakage emergency treatment device ”. The device can be widely used in LNG tanker. When the vehicle LNG storage tank, cylinder valve or pipe fittings leak occurs, you can flip the tank body, relying on valve spool valve seat sealing surface and sealing surface compression, through the valve core gravity and internal media pressure double Role, to achieve the set of dangerous chemicals tank
