he automatic drainage device is used for automatically removing condensate from the lower part of the pipeline, the oil-water separator, the gas tank and the bottom of various filters. It can be installed in places where artificial sewage is inconvenient, such as high, low and narrow places. It can also prevent the artificial drainage from being forgotten and the compressed air from being re-polluted by condensate water. There is an air bottle < equivalent to a balloon > in the automatic drain. In the anhydrous state, under the action of air pressure, the air bottle blocks the outlet.
Water accumulates in the drain. After reaching a certain water level, buoyancy is greater than air pressure. The air bottle floats up, the drain opens, and the water is discharged under the action of air pressure. At the same time, buoyancy decreases, and the air bottle drops to block the drain.
