The adjusting piece 4 is rotatably arranged on the valve body 1, and the adjusting piece 4 is in linkage with the valve core 5; when the adjusting member 4 is rotated in the circumferential direction, it is adapted to drive the valve body 5 to move upward or downward to open or close the valve body 1. The sealing buffer part 6 is sleeved outside the valve core 5, and the sealing buffer part 6 is linked with the valve body 1; when the valve core 5 moves downwards to close the valve body 1, the lower end of the sealing buffer part 6 abuts against the sealing step 13 in the valve body 1 to seal the valve body 1; at this time, the sealing cone 52 and the sealing disc 61 are simultaneously abutted against different positions of the sealing step 13 in the valve body 1, so that the sealing effect of the valve body 1 is improved; when the valve core 5 moves upwards to open the valve body 1, the upper end of the sealing buffer part 6 abuts against the lower end wall of the first sealing sleeve 11, so as to buffer the impact force of the valve core 5 on the adjusting piece 4. The condition that the threaded connection is loose at the joint of the valve core 5 and the adjusting piece 4 is avoided, meanwhile, the thrust of the valve core 5 to the adjusting piece 4 is reduced, and the service life of the device is prolonged.

The connecting rod 53 is fixed at the upper end of the positioning column 51, and the connecting rod 53 is linked with the adjusting member 4. The connecting rod 53 is adapted to move upwards or downwards simultaneously with the connecting post 43, while the connecting post 43 is able to rotate circumferentially with respect to the connecting rod 53. In order to avoid leakage of air flow along the gap between the positioning column 51 and the first sealing sleeve 11, a plurality of sealing rings 14 are fixed on the inner wall of the first sealing sleeve 11, the sealing rings 14 are sleeved on the outer wall of the positioning column 51, and the positioning column 51 can vertically slide up and down relative to the sealing rings 14.
In order to improve the service life, the sealing buffer 6 includes: the sealing disc 61, the two lifting plates 62 and the return spring 63, wherein a stepped groove 54 is formed in the outer wall of the lower end of the positioning column 51 along the circumferential direction; the sealing disc 61 is sleeved on the outer wall of the positioning column 51 in a lifting manner, and the sealing disc 61 can slide and seal on the inner wall of the stepped groove 54; the sealing disk 61 can vertically slide along the axial direction on the outer wall of the positioning column 51, and the diameter of the sealing disk 61 is larger than that of the positioning column 51.

When the connecting column 43 drives the positioning column 51 to move downwards, the sealing disc 61 abuts against the sealing step 13 before the sealing cone 52, and as the positioning column 51 continues to move downwards, the sealing disc 61 is pressed by the sealing step 13 and keeps an upward moving state relative to the positioning column 51, at this time, the sealing disc 61 presses the return spring 63, and meanwhile, the sealing disc 61 drives the lifting plate 62 to move upwards, so that the upper end of the lifting plate 62 can be inserted into the first buffer plate 64 and the second buffer plate 65; preferably, the lifting plate 62 is arc-shaped and adapted to the positioning column 51, and meanwhile, a through groove adapted to the lifting plate 62 is formed in the positioning column 51, the through groove extends along the axial direction of the positioning column 51, and the lifting plate 62 can vertically slide up and down in the through groove. And when the sealing cone 52 abuts against the sealing step 13, the sealing disk 61 and the sealing cone 52 simultaneously play a role in sealing the valve body 1. At the same time, the lifting plate 62 pushes the first buffer plate 64 and the second buffer plate 65 to move against each other, and also has the effect of sealing the air passage 55.
