The invention discloses a train water feeding joint. The train water feeding joint comprises a main water pipe, a rear joint pipe, a front water feeding joint, a sealing block, a spring and a valve element, wherein the main water pipe is hollow and two ends of the main water pipe are open; the rear joint pipe is connected to the tail part of the main water pipe; the front water feeding joint is connected to the front end of the main water pipe, and a connecting element conveniently connected with a train water filling nozzle is connected with the front of the front water feeding joint; the sealing block is mounted on the main water pipe and located at the inner side of the front water feeding joint; the spring is installed in the main water pipe; the valve element is installed in the frontwater feeding joint and extends into the connecting element; the valve element and the sealing block move synchronously; and a plurality of radial through holes are formed in the end, close to the sealing block, of the valve element. The train water feeding joint is reasonable in design, simple in structure and convenient to use, is installed between a water source water pipe and the train waterfilling nozzle, can play a role of a joint and a valve, can divide the main water pipe into two independent spaces through reasonable design of the sealing block, and can communicate or close the twoindependent spaces through reasonable cooperation with the valve element and movement of the valve element. Therefore, the train water feeding joint can play a role of the valve during water feeding.
本发明公开了一种列车上水接头,包括主水管,空心两端开口;后接头管,连接于主水管的尾部;前上水头,连接于主水管的前端,并在该前上水头前连接有便于与列车注水口连接的连接件;密封块,安装于主水管并位于前上水头内侧;弹簧,安装于主水管内,以及阀芯,安装于前上水头内并延伸到连接件内,该阀芯与密封块同步移动,在阀芯靠近密封块端开设有数个径向的通孔;本发明设计合理,结构简单,使用方便,安装于水源水管与列车注水口之间,能够起到接头和阀门的作用,合理的设计密封块,能够将主水管分隔为两个独立的空间,并通过合理配合阀芯,通过该阀芯的移动能够将两个独立的空间连通或关闭,从而实现上水时可做阀门的作用。
