Description

Technical Field

[0001] The utility model relates to the technical field of pipe joints, in particular to an EGR water pipe with a sealing connection mechanism. Background Art

[0002] EGR is the abbreviation of exhaust gas recirculation, which means returning part of the exhaust gas discharged by the engine to the intake manifold and re-entering the cylinder together with the fresh mixture. The EGR water pipe is a component in the emission control system of an automobile engine. The EGR water pipe is usually sealed and connected to the outer shell of the cooler by welding.

[0003] The EGR water pipe with a traditional sealing connection mechanism still has some shortcomings. Since the EGR water pipe is sealed and connected to the cooler housing by welding, this sealing method requires the entire assembly to be removed and complex welding work to be performed when the EGR water pipe leaks, which makes it inconvenient for staff to disassemble and repair, thereby increasing the difficulty of maintenance and repair. For this reason, we propose an EGR water pipe with a sealing connection mechanism. Utility Model Content
