The present invention relates to a condensate drain trap of a compressor, and more particularly, a compressor for treating condensate generated in an inter cooler cooling a high temperature and high pressure compressed air discharged from a compressor. Of the condensate drainage system.

Due to the advanced development of the industry, various industrial field equipments and industrial equipments are becoming unmanned automation system, and pneumatic equipment using air is used throughout the industry because it is economical and excellent in safety.

The pneumatic equipment is driven by using compressed air generated from the compressor, and the compressed air is supplied directly to the pneumatic equipment through an air supply pipe or an air hose, or is supplied with a water or foreign matter removed through a purifying device.

Meanwhile, an intercooler for cooling and condensing compressed air generated from a compressor to remove water is connected to a drainage system for discharging condensed water generated when water is removed from the compressed air.

1 is a view schematically showing a conventional condensate drainage system.

Referring to the drawings, the conventional condensate drainage system 10 is composed of an intercooler 1 and a drain trap 2. The compressed air of high temperature and high pressure passing through the compressor (not shown) is introduced into the intercooler 1, and is discharged after being exchanged with cooling water passing through the tube bundle 3.

At this time, the condensate generated in the intercooler 1 is collected into the drain trap 2 by using the slope of the intercooler 1, and when a certain level of condensate is collected in the drain trap 2, the drain detects the condensate level. The trap 2 will discharge the condensate to the outlet.

However, in such a conventional condensate drainage system, when the air pressure and flow rate inside the intercooler are high, air eddy occurs, and condensate does not collect well into the drain trap, and the pressure balance between the intercooler and the drain trap is not balanced. Therefore, there is a problem that the condensate is not easily discharged.

Has a combined configuration.

In addition, the rod 24 of the solenoid 25 is connected to one end of the opening and closing lever 23 by the link 27.

Therefore, as the opening / closing valve 23 connected to the rod 24 and the link 27 driven by the solenoid 25 is rotated, the opening and closing valve 23 is automatically opened and discharged.

However, the condensate drain device according to the prior art as described above is difficult to install the solenoid for opening and closing the ball valve, complicated and requires a lot of space according to the installation, there is a problem that the workability and productivity is lowered, it is electrically operated and installed After the initial operation there is no problem, but as time goes by, problems such as condensate splashing and leakage occur, resulting in the long-term operation.
