[0033] Working principle:

[0034] Under normal conditions, gas enters the valve core cavity from the gas inlet 7, and the valve core 4 is pushed by the gas to close the valve core contact surface 4-4 to the valve body contact surface 10.

The first correction hole 4-1 is connected to the first working hole 8, and the second working hole 9 is connected to the valve core exhaust hole 4-2. The gas enters the first correction airbag cylinder 12 from the first working hole 8. The moving end of the first correction airbag cylinder 12 pushes the correction rod 14 to rotate around the end, changing the friction angle between the correction rod 14 and the conveyor belt 11, so that the conveyor belt 11 returns to the right position. The exhaust of the second correction airbag cylinder 13 is discharged through the second working hole 9, the valve core exhaust hole 4-2, and the valve stem exhaust hole 1-1.

[0036] The conveyor belt 11 deflects to the other side, and the valve stem 1 and valve core 4 are driven to rotate to the other side through the fork rod 16. The second correction hole 4-3 is connected to the second working hole 9, and the valve core exhaust hole 4-2 is connected to the first working hole 8. The gas enters the second correction airbag cylinder 13 from the second working hole 9. The moving end of the second correction airbag cylinder 13 pushes the correction rod 14 to rotate around the end, changing the friction angle between the correction rod 14 and the conveyor belt 11, so that the conveyor belt 11 returns to the right position. The exhaust of the first correction airbag cylinder 12 is discharged through the first working hole 8, the valve core exhaust hole 4-2, and the valve stem exhaust hole 1-1.
