Abstract
The utility model discloses an exhaust manifold capable of reducing eddy phenomenon. The exhaust manifold comprises a manifold (1) and a plane flange (2), wherein the manifold (1) comprises four bend air pipes (3) and a main air pipe (4), one ends of the four bend air pipes (3) are communicated with the main air pipe (4), the other ends of the four bend air pipes (3) are connected onto the plane flange (2), four through holes (5) matched with the bend air pipes (3) are arranged on the plane flange (2), the through holes are stair holes, the bend air pipes (3) penetrate through small holes (6) of the through holes (5) and are fixedly welded with the plane flange (2) at the position of gaps (8) between the bend air pipes (3) and the inner wall of large holes (7) of the through holes (5). The exhaust manifold has the advantages that the through holes of the plane flange are designed to be stair holes, and the bend air pipes enter from the small ends of the through holes and then are fixedly welded in the gaps between the bend air pipes and the large ends of the through holes, so that the phenomenon of serious eddy caused by the fact that craters are higher than the bend air pipes, and exhausting is smooth.
Description
Technical field
The utility model relates to a kind of gas exhaust manifold, particularly relates to a kind of gas exhaust manifold that reduces vortex phenomenon.
Background technique
Gas exhaust manifold links to each other with engine cylinder, the exhaust of each cylinder is put together import exhaust manifold, has the pipeline of difference.Requirement to it mainly is to reduce exhaust resistance as far as possible, and avoid phase mutual interference between each cylinder.
Existing manifold all is installed in the outlet of cylinder through a face-flange; Manifold generally all is that welding is fixing in the hole of face-flange; Because fixing between the two the needs fully; All be higher than manifold ports so stay crator after the welding, can cause serious vortex phenomenon like this, thereby cause exhaust to have some setbacks.
The model utility content
The purpose of the utility model promptly is to overcome the deficiency of present technology, and a kind of gas exhaust manifold that reduces vortex phenomenon is provided, and has solved existing bend tracheae and face-flange welding means of fixation and can cause serious vortex phenomenon, the drawback that causes exhaust to have some setbacks.
The utility model is realized through following technological scheme: reduce the gas exhaust manifold of vortex phenomenon, comprise manifold and face-flange, described manifold comprises four bend tracheaes and main gas pipe; One end of four bend tracheaes is connected with main gas pipe, and the other end is connected on the face-flange, and the bend tracheae is connected with main gas pipe is integrated; The other end of main gas pipe is connected to purifier through a single hole flange, and described face-flange is provided with four through holes that match with the bend tracheae, and through hole is a shoulder hole; Through hole is made up of aperture and macropore; The bend tracheae passes the aperture in the through hole, and its mouth of pipe is arranged in the inside of the macropore of through hole, bend tracheae and aperture interference fit; Leave the space between the inwall of bend tracheae and macropore, weld fixing between bend tracheae and the face-flange in the gap.
Described face-flange is provided with a plurality of supports.
The length of described bend tracheae in macropore is not less than 0.3cm.
The width in described space is not less than 1cm.
The beneficial effect of the utility model is: the via design of face-flange is become shoulder hole; The bend tracheae gets into from the small end of through hole; Welding is fixing in the slit between bend tracheae and the big end of through hole then; Avoid the crator height to go off the curve tracheae and cause serious vortex phenomenon, made exhaust more smooth and easy.

Embodiment
Below in conjunction with embodiment the utility model is done further to specify, but the structure of the utility model is not limited only to following examples:
Embodiment
Shown in Fig. 1～5, reduce the gas exhaust manifold of vortex phenomenon, comprise manifold 1 and face-flange 2; Described manifold 1 comprises that an end of four bend tracheaes 3 and 4, four bend tracheaes 3 of main gas pipe is connected with main gas pipe 4, and the other end is connected on the face-flange 2; Bend tracheae 3 and 4 integrated connections of main gas pipe, the other end of main gas pipe 4 is connected to purifier through a single hole flange, and described face-flange 2 is provided with four through holes 5 that match with bend tracheae 3; Through hole 5 is a shoulder hole, and through hole 5 is made up of aperture 6 and macropore 7, and bend tracheae 3 passes the aperture 6 in the through hole 5; Its mouth of pipe is arranged in the inside of the macropore 7 of through hole 5; Bend tracheae 3 and aperture 6 interference fit leave space 8 between the inwall of bend tracheae 3 and macropore 7, between bend tracheae 3 and the face-flange 2 in the space 8 places weld and fix.
Described face-flange 2 is provided with a plurality of supports 9, is used for fixing.
The length of described bend tracheae 3 in macropore 7 is not less than 0.3cm.
The width in described space 8 is not less than 1cm.
Because be between bend tracheae 3 and face-flange 2 in the space 8 places weld fixingly, so crator is stayed in the space 8, avoid making exhaust smooth and easy because of the crator height tracheae 3 of going off the curve causes serious vortex phenomenon.
So, can realize the utility model well.
