The invention discloses an air inflation part, a railway brake valve and a detection method thereof, and relates to the technical field of railway brake valves, the air inflation part and an acceleration brake structure are included, and the air inflation part and the acceleration brake structure are communicated through a train pipe; the acceleration brake structure comprises a train pipe, a local reduction valve, a local reduction chamber, a first local reduction valve and an exhaust port, the train pipe is communicated with the local reduction valve, the local reduction valve is communicated with the local reduction chamber and the first local reduction valve, and the first local reduction valve is communicated with the exhaust port; the air inflation part comprises a train pipe, an air inflation shrinkage plug, an air inflation check valve and an auxiliary air cylinder, the air inflation check valve is arranged between the train pipe and the auxiliary air cylinder and prevents pressure air in the auxiliary air cylinder from flowing back into the train pipe, and the air inflation shrinkage plug is arranged on the side, close to the auxiliary air cylinder, in the train pipe. The structure of the inflation part and the acceleration brake structure adapting to small pressure reduction brake are optimized from the design source, the structure is simplified, and the reliability is improved.
