Abstract

A sealing device for an exhaust manifold includes a main pipe having a connection portion including a mounting groove formed at an interior circumferential surface; a sub pipe having a protruding portion at one end portion, the sub pipe being coupled to the main pipe in a state in which the protruding portion is inserted into the connection portion; a valve mounted at the mounting groove within the connection portion; and a gasket interposed between the protruding portion and the valve within the connection portion.

Description

Technical field [0001] The invention relates to a sealing device for an exhaust manifold. The present invention more specifically relates to the following sealing device for exhaust manifolds, which can prevent exhaust gas from leaking between the connection parts of the exhaust manifolds formed in a separate form. Background technique [0002] Generally, the intake and exhaust systems of a vehicle supply air to the engine through an intake manifold, the air is supplied to the combustion reaction in the engine, and then the air is discharged to the outside through the exhaust manifold. [0003] The exhaust gas generated in the engine of the vehicle is exhausted through the exhaust system, and this exhaust system includes an exhaust line that introduces the exhaust gas to the rear side of the vehicle and a muffler installed on the exhaust line to attenuate exhaust noise. [0004] An exhaust manifold used to guide the exhaust gas discharged from each combustion chamber to the exhaust ...
