The gas storage container and pipes of Liquid-nitrogen flow standard facilities are usually con-nected by traditional dispenser nozzle.In order to solve the problems of low automation,inconvenient op-eration,an automatic lifting and positioning system is proposed.The automatic filling or disconnecting op-eration of gas storage container is realized by program control.So that the automation of testing can be im-proved,the influence of manual operation can be reduced,and the efficiency of testing can also be im-proved.
