The invention discloses an air exhaust device, a rail traffic air conditioning unit and a rail vehicle. The air exhaust device comprises a shell which is provided with an air inlet communicating with the interior of a carriage and an air exhaust port communicating with the outside; the first exhaust assembly comprises a pressure wave air door arranged at the air inlet and a fan communicated with the air inlet; the second air exhaust assembly comprises a one-way air exhaust plate, a resistance part and a limiting part, the one-way air exhaust plate is rotationally arranged on the shell, and the one-way air exhaust plate and an air outlet of the fan are oppositely arranged; wherein the pressure wave air door and the fan have an opening state and a closing state, in the opening state, the airflow force of the air outlet of the fan is larger than the closing force provided by the resistance part, and the one-way exhaust plate is opened, so that the internal airflow is exhausted from the exhaust outlet; and in the closed state, the resistance piece provides closing force for the one-way exhaust plate, so that the one-way exhaust plate is closed, external airflow is prevented from entering from the exhaust outlet, and when the one-way exhaust plate is in the closed state, the side, close to the draught fan, of the one-way exhaust plate abuts against the limiting piece.

    本发明公开一种排风装置、轨交空调机组和轨道车辆,排风装置包括壳体,设有与车厢内部连通的进风口和与外界连通的排风口;第一排风组件,包括设置于进风口的压力波风门和与进风口连通的风机;第二排风组件,包括单向排风板、阻力件和限位件,单向排风板转动设置于壳体上,且单向排风板与风机的出风口相对设置;其中,压力波风门和风机具有开启状态和关闭状态,在开启状态,风机的出风口的气流力大于阻力件提供的关闭力,单向排风板开启,以使内部气流由排风口排出;在关闭状态,阻力件向单向排风板提供关闭力,使单向排风板关闭,以阻止外界气流自排风口进入,且单向排风板在关闭状态下,单向排风板靠近风机的一侧与限位件抵接。
