旅客列车自动锁紧脱落上水方法

本发明公开了一种旅客列车自动锁紧脱落上水方法，包括如下步骤：S1，在上水管接头的内部设置锁紧结构、止水结构及弹簧结构，锁紧结构用于锁紧列车注水嘴，止水结构能够在封闭位置与导通位置之间运动，并在弹簧结构的作用下，使得止水结构初始状态处于封闭位置；S2，上水员将上水管接头套上列车注水嘴，列车注水嘴挤压止水结构，以将止水结构从封闭位置挤压到导通位置，同时使弹簧结构储存弹力；S3，上水员调节锁紧结构，使得上水管接头与列车注水嘴之间锁紧，然后开始上水；S4，上水完成后，再次调节锁紧结构，使得上水管接头与列车注水嘴之间松开；S5，弹簧结构释放弹力，使得列车注水嘴自动脱落，并使止水结构从导通位置回到封闭位置。 The invention discloses an automatic locking and disengaging water feeding method for a passenger train, wherein the automatic locking and disengaging water feeding method comprises the following steps that: S1, a locking structure, a water stopping structure and a spring structure are arranged in a water feeding pipe connector, the locking structure is used for locking a train water injection nozzle, the water stopping structure can move between a closed position and a conducting position, and under the action of the spring structure, the initial state of the water stopping structure is in a closed position; S2, a water supply worker sleeves the train water injection nozzle with a water supply pipe connector, th
