Ordinary air plug performance can’〖KG-*2〗t meet actual needs of the coal mine reducer. A new composite structure air plug with steel and rubber was studied. The pressure difference on both sides of the rubber lip was used to control the opening size of the lip, to achieve functions of breathing and sealing.Practice proves that the new type of composite air plug can ventilate and control the oil leakage effectively.
