The invention relates to a pressure relief system for a high-speed train entering and exiting a tunnel by adopting a pressure relief ventilation pipeline, which adopts a non-sealed train pressure relief structure to adjust compression waves generated by a train head when the advancing train enters a tunnel section so as to reduce the pressure borne by a train body and passengers in the train and ensure the comfort of the passengers. The pressure relief channel is used for relieving the pressure of air on the train, so that the influence of sudden pressure change on train running and passengers in the train is reduced. The pressure relief channel comprises three modes: in the first mode, a ventilation pipeline for pressure relief is independently arranged at the position tightly attached to the interior of the car roof; according to the second mode, adjustment is carried out on the basis of an original air conditioner ventilation pipeline at the train roof for pressure relief; and according to the third mode, adjustment is carried out on the basis of an original exhaust pipeline at the bottom of the train for pressure relief. When the train drives into the tunnel, the pressure sensing device senses pressure sudden change, the air inlet valve and the air outlet valve are opened through signal transmission, and air flows into the ventilation pipeline for pressure relief.

    本发明涉及一种采用卸压通风管路给高速列车进出隧道时卸压系统,采用非密封式列车卸压结构来调节行进列车进入隧道区间时车头产生的压缩波以降低列车车体以及车内乘客所承受的压力,保证乘客舒适性。本发明通过卸压通道来卸除空气对列车产生的压力,从而达到减小压力突变对列车行驶与车内乘客的影响。该卸压通道包括三种方式:第一种,在紧贴车顶内部处单独设置卸压用通风管道;第二种,在列车车顶处原有的空调通风管道基础上进行调整用于卸压;第三种,在列车车底处原有的排风管道基础上进行调整用于卸压。当列车驶入隧道时,压力传感设备感受到压力突变,通过信号传输打开空气进口阀门与空气出口阀门,空气流入卸压用通风管道。
