The above method has the problem of poor exhaust volume adjustment effect due to low adjustment accuracy during the adjustment process. Secondly, the existing adjustable exhaust volume device for air compressors cannot buffer the gas during use, which causes the impact force of the gas in the exhaust process to directly act on the valve plate, which easily causes the valve plate to wear and leads to a short service life.
