The invention discloses a two-channel block valve and a railway stone ballast hopper car, and relates to the field of railway wagons, the two-channel block valve comprises a valve body, two channels are arranged in the valve body along the length direction, an upper channel valve core and a lower channel valve core are respectively arranged on the channels, and a linkage shaft is arranged between the upper channel valve core and the lower channel valve core; one end of the valve core is arranged in the valve body and is connected with the upper passage valve core, and the other end of the valve core is connected with the handle; the handle rotates to enable all the upper passage valve elements and the lower passage valve elements to rotate together, and the communicating states of the two passages are kept consistent; the cut-off valve can control opening and closing of two sets of independent passages at the same time, and solves the problem that two cut-off cocks of linkage opening and closing passages of bottom doors on the two sides of an existing stone ballast hopper car are not trained in place, so that opening and closing of operators are not synchronous.

    本发明公开了一种双通路截断阀及铁路石砟漏斗车,涉及铁路货车领域,包括:阀体,内部沿长度方向设置有两条通路,通路上分别设置有上通路阀芯和下通路阀芯,两者之间设置有联动轴;阀芯,一端设置在阀体的内部并与上通路阀芯连接,阀芯的另一端与手把连接;手把转动能够使所有上通路阀芯和下通路阀芯一同转动,并保持两条通路的连通状态一致;该截断阀可同时控制两套独立通路的开闭,解决既有石砟漏斗车两侧底门联动开闭通路的两个截断塞门培训不到位导致操作人员开闭不同步的问题。
