A gas leakage prevention cover includes an inlet having a cross section area corresponding to a cross section area of a duct into which the cover is inserted, an outlet having a smaller cross section area than the cross section area of the inlet, and a step formed at a predetermined angle in a direction toward the outlet on a predetermined position of the cover. The cover has a ring shape and is configured to enable fluid to flow through an interior space of the cover from the inlet to the outlet. 本发明涉及种防漏气盖和具有防漏气盖的排放歧管，该防漏气盖包括：入口，具有的截面面积对应于防漏气盖插入其中的管道的截面面积；出口，具有的截面面积小于入口的截面面积；以及梯级，在朝向出口的方向上以预定角度形成在防漏气盖的预定位置上。防漏气盖具有环形形状并且构造成使得流体能够从入口至出口流动通过防漏气盖的内部空间。
