Embodiment Construction

[0008] see figure 1 , the present invention includes an air compressor motor 1, an air compressor 2, a one-way valve 3, an oil-water separator 4, a four-circuit protection valve 5, a first pressure regulating valve 6, a first air storage cylinder 7, a safety valve 8, an air pressure Relay 9, second air storage cylinder 10, second pressure regulating valve 11, hand brake valve 12, shuttle valve 13, booster type brake cylinder 14, pedal brake valve 15 and relay valve 16.

[0009] The working principle of the present invention is: the air compressor motor 1 drives the air compressor 2 to work, the compressed air passes through the one-way valve 3 and the oil-water separator 4 for automatic drainage, and then passes through the four-circuit protection valve 5 to the first air storage cylinder 7 and the first air storage cylinder 7. Two air storage cylinders 10 are inflated, and when the air pressure of the first air storage cylinder 7 or the second air storage cylinder 10 reaches ...

Abstract

The invention discloses an anti-leakage two-way air braking system for a variable-frequency speed-regulating industrial and mineral electric locomotive. The system comprises an air compressor motor, an air compressor, a check valve, an oil-water separator, a safety valve, an air pressure relay, a hand braking valve, a booster-type braking cylinder, a pedal braking valve, a four-loop protecting valve, a first pressure regulating valve, a second pressure regulating valve, a first air storing cylinder, a second air storing cylinder, a shuttle valve and a relay valve. In the system, the four-loopprotecting valve is arranged for effectively protecting different air supplying branches, so the other branches are capable of normally working without being influenced by the leakage of any branch. Therefore, the system is very reliable and safe.

Description

technical field [0001] The invention relates to an air brake system, more specifically a leak-proof two-way air brake system for industrial and mining electric locomotives with variable frequency speed regulation. Background technique [0002] The most traditional industrial and mining electric locomotive air brake system adopts a simple pressurized brake cylinder air brake system, which is mainly composed of an air compressor motor, an air compressor, a one-way valve, an oil-water separator, an air storage cylinder, a safety valve and It consists of a pressure relay, a pressure regulating valve, a brake operating valve, and a pressurized brake cylinder. When the brake operating valve is in the braking position, the pipeline between the brake cylinder and the air storage cylinder is connected, and the pressure air in the air storage cylinder is supplied to the brake cylinder through the pipeline, and the pressure of the brake cylinder increases to push the piston rod to exte...
