Specifically, by the way that a part for exhaust valve plate 100 is provided towards into the bending of exhaust valve port side, so that row
The end of air valve plate 100 forms amount of warpage, also, by rationally controlling the height of the warping amount of end portion of exhaust valve plate 100 so that
During assembling, between the exhaust valve plate 100 and exhaust valve port 212 after installation in the presence of pressure, it is also possible to exhaust valve plate
100th, the mismachining tolerance of the exhaust valve port 212 and the mounting surface of exhaust valve plate 100 that coordinate with exhaust valve plate 100 etc. plays compensation
Effect so that the exhaust valve plate 100 after installation can be close to exhaust valve port 212, effectively reduce the leakage rate of air-valve assembly, and
And, one end of exhaust valve plate 100 is to the structure of exhaust valve port side bending it is also possible that the bullet that exhaust valve plate 100 passes through itself
Property deformation obtain bigger screen resilience, and then shorten evacuation time, improve exhaust efficiency.
