Abstract

The invention relates to an automatic water draining valve for locomotives, which is a water draining and pollution discharging device for railway locomotives and is composed of two parts such as a water draining valve and a heating rod; the automatic water draining valve is a water draining valve characterized by high capacity and two-stage action mode; the automatic water draining valve is driven by compressed air in a pipeline as control air source when an air compressor is unloaded; water drainage and pollution discharge are carried out by the control air source; the automatic water draining valve is provided with a flange-shaped mounting bracket and is mounted on the bottom part of an air cylinder conveniently or is mounted on the bottom part of an air filter; a temperature-controlled heating rod is arranged; and a heating valve body is started automatically below 4 degrees centigrade so as to prevent condensed water in the water draining valve from being frozen at low temperature environment. According to the invention, the automatic water draining valve aims to discharge pollutant liquid such as condensed water, oil and the like out of a locomotive air cylinder or the air filter; in addition, the automatic water draining valve is an important component for purifying compressed air or ensuring compressed air to be dried in air pipelines systems on the railway locomotives, internal combustion locomotives, urban rail vehicle and subways.

Description

technical field [0001] The invention relates to an automatic drain valve for locomotives, which is a drainage and sewage device for railway locomotives, and aims to discharge condensed water, oil and other pollutant liquids from locomotive wind cylinders or air filters. Background technique [0002] At present, the air cylinder and air filter of the locomotive are manually drained, which cannot be operated during driving, and also increases the workload of use and maintenance. Contents of the invention [0003] The purpose of the present invention is to solve the above problems, change the working mode of the drain valve, and provide an automatic drain valve for locomotives that better meets the development needs of urban rail locomotives and subway rail locomotives. [0004] The technical solution of the present invention: an automatic drain valve for locomotives, characterized in that the automatic drain valve is composed of two parts: a drain valve and a heating rod; ...
