Description

Water removing device for air storage tank

Technical Field

The utility model relates to the field of compressor matched equipment, in particular to a water removing device of an air storage tank.

Background

The utility model patent with the application number of CN201810151134.1 discloses a device for draining accumulated water in an air storage tank of an air compressor, and a drain pipe of the device is communicated with a cavity of the air storage tank in a sealing manner. The lower end port of the air storage tank is positioned at the bottom of the air storage tank cavity; the upper end port of the valve is communicated with a water channel of a two-way valve in a sealing way; the two-way valve is fixed on the wall of the gas storage tank; the other end of the two-way valve water channel is communicated with a water flowing pipe in a sealing way. When the air storage tank stores compressed air, the pressure in the air storage tank is larger than the external pressure, the valve is opened, and accumulated water is discharged through the drain pipe, the valve and the water flowing pipe under the action of the pressure difference between the inside and the outside of the air storage tank. The reason why the water accumulation is generated is that the compressed air is supplied after passing through the cold dryer, but the compressed air dried by the cold dryer can not completely remove the water in the compressed air and still contains a large amount of water.
