Embodiment Construction

[0029] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0030] For ease of understanding the present invention, at first existing JZ-7 braking system is briefly introduced:

[0031] The existing JZ-7 braking system includes a relay valve 3, a main air pipe A0021 connected to the main air cylinder, a train pipe 008 and a gate blocking pipe 001, wherein one end of the train pipe 008 is connected with the train pipe A passing through the vehicle, The relay valve 3 has a blocking valve, an air supply valve and an exhaust valve. One side of the air supply valve is connected...

Abstract

The invention provides an auxiliary device for improving the braking speed of the JZ-7 braking system, the JZ-7 braking system includes a relay valve, a train pipe, a gate blocking pipe and a main air pipe A connected to the main air cylinder, One side of the exhaust valve of the relay valve is connected to the train pipe, the other side of the exhaust valve is connected to the external space, and one end of the gate blocking pipe is connected to the gate control pipeline; The auxiliary device for moving speed includes the control system, brake button A, brake button B, the first branch, the second branch, the third branch, the fourth branch, the pressure sensor and the main air duct connected to the main air duct A. Tube B. The invention is easy to operate, and when applied to the JZ-7 braking system, the braking speed is faster than that of the original JZ-7 braking system, and does not affect the use of the original JZ-7 braking system.

Description

technical field [0001] The invention relates to the manufacturing technology of railway locomotives, especially the braking technology of railway locomotives, in particular to an auxiliary device for improving the braking speed of the JZ-7 braking system. Background technique [0002] At present, most diesel locomotives use the JZ-7 braking system. The principle is that the decompression of the balanced air cylinder leads to the decompression of the train pipe. At this time, the brake cylinder of the locomotive is filled with air for braking. Movement reaction speed. Existing locomotive all is to make the train tube decompress by artificially operating the automatic brake valve (i.e. the gate), so that the whole train is braked. The decompression of the train pipe is mainly implemented through the action of the relay valve, that is, the automatic brake valve (that is, the gate) is manually pushed to the braking area, the balance air cylinder in the relay valve is decompress...
