Pressure difference is generated between the first airflow cavity and the second airflow cavity, the movable plug 53 moves towards the direction of the second separating wheel 52 and pushes against the second separating wheel 52, the intermediate airflow cavity is different from the second airflow cavity, and the second air guide hole 36, the intermediate airflow cavity and the first airflow cavity are communicated.

Compressed air enters the first connecting channel 8 through the first air inlet 6 and then enters the first air guide hole 7 from the first connecting channel 8, the compressed air in the first air guide hole 7 enters the second air guide hole 36 through the connecting pipe 38 and then enters the middle airflow cavity from the second air guide hole 36, the compressed air enters the first airflow cavity through the first through hole 54 in the middle airflow cavity and then enters the first drying tower 1 through the first air vent 33 communicated with the first airflow cavity, and the compressed air is dried in the drying tower from bottom to top.

The dried compressed air enters the airflow hole 21 on the first check valve component 4, the compressed air enters the regeneration hole 20 through the airflow hole 21, the compressed air in the regeneration hole 20 flows towards the tapered hole 19 to jack up the adjusting ball 17, so that the adjusting ball 17 moves towards the floating hole 18, at the moment, the first check valve component 4 is in an open state, the compressed air enters the first air hole 9 through the tapered hole 19 and the floating hole 18 and then enters the first connecting hole 12 through the first air hole 9, because the second air hole 10 is communicated with the first connecting hole 12, the compressed air applies pressure to the adjusting ball 17 on the second check valve component 5 through the second air hole 10 to prevent the adjusting ball 17 from moving upwards, at the moment, the second check valve component 5 is in a closed state, the compressed air enters the air outlet pipe 13 through the first air outlet hole 11 in the first connecting hole 12, and most of the dried compressed air is discharged through the air outlet pipe 13, a small portion of the compressed air enters the tee 14.

The compressed air in the three-way pipe 14 enters the annular pipe 25 in the second drying tower 2 through the second pressure reducing valve 30, the compressed air entering the annular pipe 25 through the three-way pipe 14 is at a low pressure, the compressed air enters the diversion hole 24 through the branch pipe 26 in the annular ring, then enters the regeneration hole 20 through the diversion hole 24, enters the second drying tower 2 through the airflow hole 21 in the regeneration hole 20, the compressed air in the second drying tower 2 flows from top to bottom in a low-pressure environment, moisture in the drying agent in the second drying tower 2 is released, enters the second airflow cavity through the second vent hole 34, enters the fourth vent hole 67 through the second vent hole 65, enters the vent through hole 69 from the fourth vent hole 67, enters the main vent hole 68 through the vent through hole 69, and is discharged through the silencer 71.

When the second drying tower 2 is used for drying and the first drying tower 1 is used for drying agent regeneration, the reverse is true.
