Fault Diagnosis and Treatment of 120 Brake Valves of Railroad Wagons
National Energy Group Railway is the main channel for west-east coal transportation,which is characterized by concentrated transportation capacity and high demand.With the increasing demand for heavy-duty transportation of railroad wagons,a stable and reliable braking system becomes the key to the safe operation of trains.Therefore,improving the over-haul quality of railroad wagon braking device is crucial to ensure transportation safety.120 brake valve is a key component in the railroad wagon braking system,its overhaul quality directly affects the braking performance of the train,and plays an important role in ensuring the safe operation of the train.120 brake valve overhaul focuses on the key points and difficulties mainly lies in the faults of the control valve to determine and deal with.This paper will combine the actual maintenance situ-ation,and introduce 120 type brake valve in the daily maintenance of fault diagnosis and treatment methods,in order to im-prove its maintenance quality and efficiency.
