Abstract

The invention discloses a control method and device for a locomotive brake average tube. The device comprises an air source filtering device, a first solenoid valve, a pressure boost valve, a third solenoid valve, a second solenoid valve, a control unit, a pressure detection device, a control air cylinder and a pneumatic reversing valve, wherein the first solenoid valve, the pressure boost valve and the third solenoid valve are connected with the air source filtering device and arranged on an air circuit installing plate, the second solenoid valve is connected with the air source filtering device and arranged on the air circuit installing plate, the control unit and the pressure detection device are connected with the first solenoid valve and the second solenoid valve, the control air cylinder is connected with the pressure boost valve and the pressure detection device, the pneumatic reversing valve is connected with the pressure boost valve and the third solenoid valve, and an air outlet of the pneumatic reversing valve is connected with an output port of the average tube. The working state of a locomotive local pusher engine can be set automatically, the operation of setting the working state of the locomotive local pusher engine is simplified, the precontrol pressure of the average tube is controlled in a closed-loop mode, the response speed of a brake cylinder of the locomotive pusher engine is increased, and the synchronism of the brake cylinder of the locomotive local pusher engine is improved.

Description

technical field [0001] The invention relates to the technical field of railway locomotive braking, in particular to a locomotive braking machine averaging tube control device and method. Background technique [0002] With the advancement of science and technology and the rapid development of railway technology, the demand for reconnection locomotives is increasing day by day. For reconnection locomotives running on railways, at present, domestic DK locomotives use reconnection valves to realize reconnection functions. Manually set reconnection valves To set the working state of the brake machine or the working state of the brake machine, the operation process is not simple and convenient. [0003] When the working state of the brake machine is set, the pressure of the local brake cylinder of the locomotive communicates with the pressure of the average pipe through the double valve, and the pressure of the auxiliary brake cylinder of the locomotive is controlled through the a...
