The invention discloses a locomotive sanding control device and a processing method thereof as well as a locomotive brake cabinet. The sanding control device comprises a cock and an electric pneumatic valve and further comprises an integrated gas circuit board, wherein a blast main port and a sanding pipe port are arranged on the integrated gas circuit board, connecting gas circuits among the blast main port, the cock, the electric pneumatic valve, and the sanding pipe port are integrated into the integrated gas circuit board; and a valve body port used for connecting the cock and the electric pneumatic valve is formed in the integrated gas circuit board. The connecting gas circuit and port required by the sanding control device are integrated into the integrated gas board, and modular design is adopted. After a module is mounted into the locomotive brake cabinet, the output control to the wind source is realized only if the blast main and the sanding pipe are connected to corresponding ports, and connecting a plurality of single valve bodies through a plurality of pipelines is not needed. Therefore, the modularized sanding control device has the advantages that the structure is simplified, complicated circuits do not exist, and connection, inspection and maintenance are easy.
Description
technical field [0001] The invention relates to the technical field of locomotives, in particular to a locomotive sand spreading control device and a processing method thereof, and a locomotive brake cabinet. Background technique [0002] Sanding is mainly used to prevent the locomotive from idling or sliding. How to sprinkle sand on the locomotive in a timely and appropriate amount is very important. It is generally controlled by a sand control device. [0003] The sand spreading control device generally includes an electropneumatic valve and a plug door. The inlet and outlet of the plug door are respectively connected to the inlet of the main air duct and the inlet of the electropneumatic valve, and the inlet of the electropneumatic valve is connected to the inlet of the sand spreading pipe. The plug door is generally in the normal open state, and the air source at the inlet of the main air duct is adjusted by the electro-pneumatic valve and then enters the sand spreading...
