Sealed exhaust wave combination sealing structure

Abstract

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, sealing of high-temperature fuel gas in the exhaust pipe can be achieved, and the sealing problem of segmented exhaust pipelines of an engine is effectively solved.

Description

Technical field [0001] The present invention belongs to the field of engine technology, and more particularly to a wave combination sealing structure of a sealed exhaust. Background technique [0002] The exhaust pipe is responsible for discharging the exhaust gas after the engine is burned while suffering from the continuous change of low temperature and high temperature exhaust gas, the exhaust pipe deformation, leakage. If gas leakage occurs in the exhaust pipeline, it causes environmental pollution, and severely causing serious failures in the cabin. Due to the high working temperature of the exhaust pipe, the amount of thermal expansion is large, the standard ambient temperature and the operating temperature exhaust pipeline telescopic are large. In order to avoid reliability problems such as cracks in the exhaust line, longer exhaust lines need to be segmented, but the sealing of segmented connectivity has become a challenge of the industry. Inventive content [0003] In v...
