The invention relates to the technical field of rail transit vehicles, and discloses a structure and method for accelerating air exhaust of a railway brake train pipe, in the structure, an emergency chamber, an inflation throttling hole and a service brake air exhaust valve are sequentially communicated through a train pipe, and a node between the emergency chamber and a service brake switch valve is communicated with a train pipe pressure reduction speed sensing valve through the train pipe; a node between the emergency chamber and the service brake switch valve is communicated with the emergency brake exhaust valve through a train pipe, a node between the inflation throttling hole and the service brake exhaust valve is communicated with the emergency brake exhaust valve through a train pipe, and the emergency chamber exhaust throttling hole is communicated with the atmosphere. The problems that in the prior art, the train pipe exhaust time is long, the train braking distance is long, and the longitudinal impact force during train braking is large are solved.

    本发明涉及轨道交通车辆技术领域,公开了一种加快铁路制动机列车管排风的结构及方法,该结构,紧急室、充气节流孔、常用制动排风阀通过列车管依次连通,紧急室与常用制动开关阀之间的节点通过列车管与列车管减压速度感知阀连通,紧急室与常用制动开关阀之间的节点通过列车管与紧急制动排风阀连通,充气节流孔与常用制动排风阀之间的节点通过列车管与紧急制动排风阀连通,紧急室排气节流孔与大气连通。本发明解决了现有技术存在的列车管排风时间长、列车制动距离长、列车制动时的纵向冲击力大等问题。
