The invention relates to the technical field of railway vehicles, and provides a railway vehicle and a toilet flushing system and method thereof, and the toilet flushing system of the railway vehicle comprises a toilet body, a water booster tank, a sewage tank and a central control unit. A water feeding valve and a flushing valve are arranged on the water inlet pipe in a spaced mode in the water flow direction. The water booster tank is communicated with the water inlet pipe and located between the water feeding valve and the flushing valve, and a liquid level sensor is installed in the water booster tank. The sewage box is communicated with the toilet stool body through a blow-off pipe, the sewage box is communicated with an exhaust pipe, and the exhaust pipe is provided with a vacuum pump. The central control unit is electrically connected with the liquid level sensor, the water feeding valve, the flushing valve and the vacuum pump. In the state of water leakage, the water feeding valve located at the front end of the water booster tank is used for cutting off a subsequent water path, and the problem that water leaks at the flushing valve and overflows into a vehicle body to damage equipment in the vehicle is solved.
本发明轨道车辆技术领域,提供一种轨道车辆及其便器冲水系统、方法,该轨道车辆便器冲水系统,包括便器本体、水增压罐、污物箱和中控单元。便器本体适于通过进水管连接水源,进水管沿水流方向间隔设有上水阀和冲水阀。水增压罐与进水管相连通,且位于上水阀和冲水阀之间,水增压罐内安装有液位传感器。污物箱通过排污管与便器本体相连通,污物箱连通有排气管,排气管安装有真空泵。中控单元分别与液位传感器、上水阀、冲水阀和真空泵电连接。在漏水的状态下,利用位于水增压罐前端的上水阀切断后续的水路,避免了在冲水阀处出现水泄漏造成水溢出到车体中损坏车内设备的问题。
