The invention provides an unpowered return braking device of a GOST standard locomotive and the GOST standard locomotive, the unpowered return braking device comprises a distribution valve module, the distribution valve module comprises a pressure reducing valve, the input end of the pressure reducing valve is communicated with a train pipe of the GOST standard locomotive, and the output end of the pressure reducing valve is communicated with a pre-control pipe of the GOST standard locomotive; and the pressure adjusting device is used for adjusting the output pressure of the train pipe to form the input pressure of the pre-control pipe and enabling the input pressure of the pre-control pipe to reach a preset value range. The pre-control pressure is controlled through the distribution valve module, so that the final brake cylinder pressure meets the domestic unpowered return requirement; the pressure reducing valve is arranged in front of the pre-control pipe, so that the situation that the whole train is delayed due to the fact that braking of the unpowered return locomotive is not relieved due to the fault of the pressure reducing valve is avoided; and the existing distribution valve modules are connected in parallel, so that the operation steps during unpowered return of the locomotive are simplified.
本公开提供了一种GOST标准机车的无动力回送制动装置和GOST标准机车,包括:分配阀模块,分配阀模块包括减压阀,减压阀的输入端与GOST标准机车的列车管连通,其输出端与GOST标准机车的预控管连通,以用于调整列车管的输出压力以形成预控管的输入压力,并使预控管的输入压力达到预设值范围内。本发明通过分配阀模块来控制预控压力使最终的制动缸压力符合国内无动力回送的要求;通过减压阀设置在预控管之前,避免了因减压阀故障造成无动力回送机车制动不缓解导致整列车延误;通过既有分配阀门模块与分配阀模块并联,简化机车无动力回送时操作步骤。
