Since the lift stopper 1 does not extend in the longitudinal direction, the thickness direction at a certain position on the lift stopper 1 should be a direction perpendicular to a tangent line of the above circular arc curve at that position. Since each position on the fixing portion 11 extends along the x-axis direction, the thickness direction of the fixing portion 11, i.e., the z-axis direction, is more favorable for the installation of the lift limiting member 1 by taking the z-axis direction as a positioning reference of the lift limiting member 1.

The high-pressure air flow is discharged from the exhaust hole 20 and impacts the valve sheet 3, so that the valve sheet 3 flaps the abutting wall 13 of the lift position limiting member 1 at a high frequency. Due to the arrangement of the hollow groove 120, the rigidity of the lift position limiting part 1 is reduced, the elastic deformation capacity is improved, the lift position limiting part 1 absorbs partial energy impact through the elastic deformation of the lift position limiting part 1, the contact stress borne by the valve plate 3 when the valve plate 3 slaps the lift position limiting part 1 is reduced, and meanwhile, stress concentration is avoided, so that the valve plate 3 is protected.
