Preventing external impurities from entering the air pipeline is crucial for the safety and reliability of the locomotive brake. Train connecting pipes are installed at both ends of the locomotive to supply air to the brakes of the rear vehicles; locomotives with multiple-unit operation functions are also equipped with main air connecting pipes and equalizing connecting pipes to supply air to the main air cylinders and brake cylinders of the rear multiple-unit locomotives respectively. For locomotives with dual-pipe air supply functions, the main air connecting pipe can also supply air to the equipment of passenger cars. When the locomotive is connecting to vehicles or multiple-unit locomotives, only one end of the connecting pipe is in use, and the other end of the connecting pipe needs to be fixed and the connecting pipe interface also needs to be dust-proof.
