s1, when the water level in the cylinder body reaches a certain height, the floating ball drives the link mechanism and the long sealing column to ascend, the two groups of elastic steel sheets contact with the inclined surfaces on the 10-15-degree open grooves of the long sealing column to release elastic force to provide upward supporting force for the long sealing column, after drainage is finished, the floating ball descends under the action of gravity to enable the long sealing column to descend, the inclined surfaces on the 10-15-degree open grooves of the two groups of elastic steel sheets of long sealing column contact to release elastic force to generate vertical downward force on the long sealing column to increase the sealing effect;
s2, when less condensed water is in the steam pipeline, the buoyancy is not enough to lift the long sealing column, and the rubber pad at the bottom end of the long sealing column is always in contact with the upper port of the water outlet device; when the water level rises to a certain height, the floating ball pulls the Y-shaped joint to drive the connecting rod mechanism to gradually lift the long sealing column, at the moment, the boosting device provides upward supporting force, condensed water flows out from the water outlet through the cylindrical filter screen, impurities and dirt are blocked outside and fall into the lower end cover, and the water outlet device is prevented from being blocked;
s3, after water is discharged for a period of time, the water level is reduced, the floating ball gradually reduces buoyancy and moves downwards, the long sealing column is pressed down by means of self gravity, meanwhile, the elastic steel sheet generates downward displacement, and the water outlet is quickly closed to finally separate the steam, the condensed water and the impurity and dirt.
