Abstract
Description
Technical Field
[0001] The utility model relates to the technical field, in particular to a pipe seat with a flange for fixing an exhaust manifold spray gun. Background Art
[0002] The nozzles on the exhaust manifold are located on the vertical center plane of the manifold, distal to the outlet of the main exhaust pipes. However, due to the varying diameters of the main exhaust pipes, the placement of the spray guns, if longer than 1 meter, can lead to severe vibration during engine operation without a suitable mounting assembly. This can cause the nozzles to fall, reduce reductant spraying efficiency, or cause reductant spraying onto the main exhaust manifolds, leading to corrosion. Therefore, those skilled in the art have provided a flanged pipe socket for securing the exhaust manifold spray guns to address the issues raised in the background art. Utility Model Content
[0003] (1) Technical problems solved
[0004] In response to the shortcomings of the existing technology, the utility model provides a flanged pipe seat for fixing the exhaust manifold spray gun to solve the problem that if the spray gun does not have a corresponding fixing component, the spray gun will vibrate severely when the main engine is running, which may cause the nozzle to fall off, the reducing agent spraying efficiency to become low, or the reducing agent sprayed on the large exhaust manifold will cause corrosion to the pipeline.
