The invention provides an automatic water drainage valve and an air brake system. The automatic water drainage valve comprises a valve body, wherein a water inlet channel and a water drainage channel are formed in the valve body; a valve component which automatically controls the switching-on and switching-off of the water inlet channel and the water drainage channel is arranged between the water inlet channel and the water drainage channel; a manual water drainage channel which is communicated with the water inlet channel is also formed in the valve body; and a manual control switch which controls the switching-on and switching-off of the water inlet channel and controls the switching-on and switching-off of the water inlet channel and the manual water drainage channel is arranged on the valve body. The automatic water drainage valve provided by the invention has the advantages that on one hand, automatic water drainage is realized by controlling the switching-on and switching-off of the water drainage channel through the vertical motion of the valve component; and on the other hand, manual water drainage is realized by controlling the switching-on and switching-off of the water inlet channel and the water drainage channel through the manual control switch.
Description
technical field [0001] The invention relates to valve technology, in particular to an automatic drain valve and an air brake system for locomotive air brakes. Background technique [0002] The diesel locomotive is braked by the air brake system to ensure that the locomotive can brake accurately. Among them, the air brake system includes components such as air compressor, air dryer and main air cylinder. The air compressor pumps out compressed air, which contains water, and the air is dried by an air dryer to remove moisture, and the dried air is then supplied to the main air cylinder. When the air dryer fails to work normally, there will be water in the main air cylinder, which cannot normally supply dry air to the brake pipeline. [0003] When the air dryer fails, in order to ensure that the air in the brake pipeline is dry, it is necessary to drain the accumulated water in the main air cylinder. In the existing technology, such as figure 1 As shown, a drain valve is ge...
