Sealed exhaust wave combination sealing structure

The invention provides a sealing exhaust wave combination sealing structure which comprises an air outlet pipe section, an axial wave ring, a radial expansion ring and an air inlet pipe section which are sequentially and coaxially arranged, the air inlet pipe section and the air outlet pipe section are in clearance fit and can relatively move in the axis direction, and an expansion gap is formed between the air inlet pipe section and the air outlet pipe section. An axial wave ring and a radial expansion ring are arranged in the expansion gap, and the axial wave ring can axially deform and can be in sliding fit with the inner wall of the air outlet pipe section; the radial expansion ring can deform in the radial direction and can be in sliding fit with the inner wall of the air outlet pipe section. According to the wave combined sealing structure for sealed exhaust, through combined application of the axial wave ring, the radial expansion ring, the gas inlet pipe section and the gas outlet pipe section, sealin
