The working principle is as follows:

in the using process, when a worker needs to drain accumulated water in the air compressor, the worker only needs to rotate the connecting pipe 206 and the drain pipe 108 in opposite directions to rotate the torsion spring arranged in the first torsion spring clamping groove 201, the rotation of the torsion spring drives the second connecting rotating rod 103 to rotate, the rotation of the second connecting rotating rod 103 drives the adjusting rod 102 to rotate, the adjusting rod 102 drives the spherical adjusting valve 101 to rotate, so that the through hole in the center of the spherical adjusting valve 101 is positioned right above and cannot be sealed by the sealing ring 107, accumulated water in the air compressor can be discharged from the drain pipe 108, when the accumulated water is discharged from the air compressor, the accumulated water is discharged from a large space through a pipeline, a vortex is formed at the drain outlet of the pipeline, so that the rotating blade 3031 can drive the rotating ring 303 to rotate, and the rotating ring 303 is fixedly connected with the cleaning cylinder 307 through the L-shaped connecting piece 302, therefore, the cleaning cylinder 307 can rotate, so that the cleaning connection plate 301 can rotate, so that the first cleaning brush 3011 and the second cleaning brush 3012 can rotate to clean the inside of the

problem of sealing effect any more, when accumulated water is discharged, the accumulated water acts on the water guide plate 105, so that the water guide plate 105 is always at a downward inclined angle, and because the connection angle gamma between the second connecting spring 106 and the water guide plate 105 and the drain pipe 108 is forty-five degrees, the water guide plate 105 is always at an inclined angle and cannot be completely turned over, and when the connecting pipe 206 and the drain pipe 108 rotate in opposite directions, so that the torsion spring arranged in the first torsion spring clamping groove 201 rotates, the torsion spring can drive the first connecting rotating rod 203 to rotate, the first connecting rotating rod 203 drives the exhaust baffle 204 to rotate, so that the exhaust baffle 204 is staggered with the tapered exhaust pipe 205, and because the outer end diameter of the tapered exhaust pipe 205 is large, so that impurities such as the accumulated water and iron rust dust cannot enter the tapered exhaust pipe 205 during the water discharging process, the rust chips cannot block the exhaust pipe 205, accumulated water cannot enter the second connecting circular groove 202 through the conical exhaust pipe 205 to affect the service life, when the accumulated water is completely discharged, gas can be discharged into the second connecting circular groove 202 from the conical exhaust pipe 205 and simultaneously blown onto the guide plate 304, the cleaning cylinder 307 is rotated, so that the air storage cavity of the air compressor can

not generate an acting force on the water guide plate 105, the second connecting spring 106 can reset the water guide plate 105 to the horizontal position, so that the torsion spring is reset, the rotation of the torsion spring drives the second connecting rotary rod 103 to reset, the rotation of the second connecting rotating rod 103 drives the adjusting rod 102 to reset, the adjusting rod 102 drives the ball-type adjusting valve 101 to reset, so that the through hole at the center of the ball-type adjusting valve 101 is sealed by the sealing ring 107, the torsion spring can also drive the first connecting rotating rod 203 to rotate, the first connecting rotating rod 203 drives the exhaust baffle 204 to rotate, the exhaust baffle 204 blocks the conical exhaust pipe 205, and no waste of gas is generated, and by using the connection of the torsion spring, the situation that the drain valve is always in a working state due to negligence of workers can be avoided, the error-proof effect is achieved, the waste of compressed gas in the air storage cavity of the air compressor is avoided, no external energy is used when the cleaning is performed in the air storage cavity of the air compressor, the energy of accumulated water is effectively utilized, and the practicability of the.
