The invention discloses an omega-shaped exhaust expansion joint integrated with a gradual change pipe. The omega-shaped exhaust expansion joint comprises the gradual change pipe, the gradual change pipe is a pipeline which smoothly gradually changes from a non-circular inlet into a circular outlet, the non-circular inlet end of the gradual change pipe is fixed on the non-circular inner wall of a non-circular flange, the circular outlet end of the gradual change pipe is fixedly connected with an inlet of an omega-shaped corrugated pipe set, an outlet of the omega-shaped corrugated pipe set is fixedly connected with an inlet of a circular transition pipe, and an outlet of the circular transition pipe is fixed on the circular inner wall of a circular flange. The omega-shaped exhaust expansionjoint achieves gradual change transition of different joint types, can smoothly gradually change a square exhaust port of a diesel engine into a circular pipeline and also can retard the generation of exhaust vortexes in the pipe to reduce exhaust resistance losses; and the adopted exhaust corrugated pipe set with omega-shaped corrugation has small axial and radial rigidity and large flexibility,thereby having high compensation capability for axial, radial and angular deflection, having high adaptability to the vibration and thermal expansion and cold contraction of the diesel engine and anexhaust system and being capable of effectively isolating the vibration transmission of the diesel engine.

    本发明公开了一种集成渐变管的Ω形排气膨胀接头,包括渐变管,渐变管为从非圆形入口圆滑渐变为圆形出口的管路,渐变管的非圆形入口端固定在非圆形法兰的非圆形内壁上,渐变管的圆形出口端与Ω形波纹管组的入口固定连接,Ω形波纹管组的出口与过渡圆管的入口固定连接,过渡圆管的出口固定在圆形法兰的圆形内壁上。本发明实现了不同接口型式的渐变过渡,可以将柴油机方形排气口圆滑渐变为圆形管路,且能减缓管内排气涡流的产生以降低排气阻力损失;采用的Ω形波纹的排气波纹管组轴向、径向刚度较小而柔性大,因而具有较好的轴向、径向和角度偏转的补偿能力,对柴油机和排气系统振动、热胀冷缩的适应能力强,且能有效隔离柴油机的振动传递。
