Summary of the invention
Technical problem to be solved by this invention is to provide constitutionally stable gas exhaust manifold.
The present invention addresses the above problem adopted technological scheme:
Constitutionally stable gas exhaust manifold, comprise inlet flange and exhaust flange, on described inlet flange, be vertically fixed with a plurality of arms, described arm comprises the first arm, the second arm, the 3rd arm and the 4th arm, described arm is all communicated with gathering tube, described gathering tube is communicated with mixing tube by transition tube, described mixing tube is connected on exhaust flange, between described inlet flange and mixing tube, be connected with reinforcement plate, described gathering tube and the angle between inlet flange are greater than 15 degree and are less than 60 degree, described mixing tube parallels with inlet flange, on described arm and gathering tube, be provided with reinforced sheet.
As preferably, described gathering tube and the angle between inlet flange are 20 degree.
As preferably, described gathering tube and the angle between inlet flange are 30 degree.
As preferably, described gathering tube and the angle between inlet flange are 45 degree.
Further, described reinforced sheet is arranged on the joint of arm and inlet flange and the joint of arm and gathering tube.
Further, described reinforcement plate is connected to the stage casing of mixing tube.
To sum up, the invention has the beneficial effects as follows:
1, the present invention will have certain angle between the gathering tube of gas exhaust manifold and inlet flange, and the impact force of scavenging action on gathering tube is broken off, and the power perpendicular to gathering tube direction reduces, and strengthens the stability of gas exhaust manifold.
2, the present invention utilizes gathering tube, mixing tube fully to mix gas, effectively reduces the impact force that gas is discharged.
3, the present invention utilizes reinforcement plate and reinforced sheet respectively the joint of mixing tube and arm to be fixed, and further strengthens the impact resistance of gas exhaust manifold, strengthens stability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Mark and corresponding component title in accompanying drawing: 1, inlet flange; 2a, the first arm; 2 b, the second arm; 2c, the 3rd arm; 2d, the 4th arm; 3, reinforced sheet; 4, gathering tube; 5, mixing tube; 6, reinforcement plate; 7, exhaust flange; 8, transition tube.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention is done to detailed description further, but embodiments of the present invention are not limited to this.
Embodiment 1:
Constitutionally stable gas exhaust manifold as shown in Figure 1, comprise inlet flange 1 and exhaust flange 7, on described inlet flange 1, be vertically fixed with a plurality of arms, described arm comprises the first arm 2a, the second arm 2b, the 3rd arm 2c and the 4th arm 2d, described arm is all communicated with gathering tube 4, described gathering tube 4 is communicated with mixing tube 5 by transition tube 8, described mixing tube 5 is connected on exhaust flange 7, between described inlet flange 1 and mixing tube 5, be connected with reinforcement plate 6, described gathering tube 4 and the angle between inlet flange 1 are greater than 15 degree and are less than 60 degree, described mixing tube 5 parallels with inlet flange 1, on described arm and gathering tube 4, be provided with reinforced sheet 3.In the present embodiment, inlet flange is connected on motor, and engine exhaust is discharged successively after arm, gathering tube 4, transition tube 8, mixing tube 5.Because arm is very short, gas enters gathering tube 4 by arm very soon, 4 pairs of gases of gathering tube tentatively mix, enter again transition tube and mixing tube 5, gas is carried out to secondary mixing, gas is fully mixed, utilize twice mixing, increased the path-length that gas is discharged, the impact force while reducing gas discharge.The exhaust of motor enters gathering tube again through arm, be that exhaust meeting produces powerful impact force to gathering tube, the present embodiment is mainly studied the angle between gathering tube inlet flange, scavenging action is studied in the angle of gathering tube, to reduce the impact force of exhaust to gathering tube.By mechanical analysis, shown, when gathering tube parallel with inlet flange, be gathering tube and arm when perpendicular, the impact force of exhaust acts on gathering tube, now completely, exhaust is maximum to the impact force of gathering tube, now the structure of gas exhaust manifold is least stable, and it mostly adopts this kind of mode existing gas exhaust manifold, and now, gathering tube has certain rebound effect to exhaust, can make part exhaust get back to arm.When gathering tube and inlet flange not parallel, when gathering tube and arm out of plumb, the impact force of scavenging action on gathering tube is broken off, the power perpendicular to gathering tube direction reduces.Experiment and theory all show, when the angle of gathering tube and inlet flange is larger, but can not equal 90 degree, and its exhaust is less to the impact force of gathering tube.Because gas exhaust manifold is connected on automobile, the space size of its vehicle is limited, and when the angle of gathering tube and inlet flange is larger, its space range taking is larger.Angle between gathering tube 4 and inlet flange 1 is 60 while spending, and it can reduce half by impact force, and now, the stability of gas exhaust manifold is fine.Angle between gathering tube 4 and inlet flange 1 is less than 15 while spending, though it can reduce impact force, still, its poor effect.Consider, the angle between gathering tube 4 and inlet flange 1 is greater than 15 degree and is less than 60 degree.Due to the limited space of automobile, by transition tube, mixing tube 5 is paralleled with inlet flange 1, can effectively reduce gas exhaust manifold and take volume, conserve space.In order to make the degree of mixing of gas high, mixing tube 5 has certain length, and 6 pairs of mixing tubes of reinforcement plate are fixed, and further strengthen the stability of gas exhaust manifold.Reinforced sheet 3 is arranged on arm and gathering tube 4, strengthens the linkage structure of arm and gathering tube, strengthens the stability of gas exhaust manifold.
Embodiment 2:
Constitutionally stable gas exhaust manifold as shown in Figure 1, the present embodiment is preferred one group of data on embodiment 1 basis, and the angle between gathering tube 4 and inlet flange 1 is 20 degree.
Embodiment 3:
Constitutionally stable gas exhaust manifold as shown in Figure 1, the present embodiment is preferred one group of data on embodiment 1 basis, and described gathering tube 4 and the angle between inlet flange 1 is 30 degree.
Embodiment 4:
Constitutionally stable gas exhaust manifold as shown in Figure 1, the present embodiment is preferred one group of data on embodiment 1 basis, and described gathering tube 4 and the angle between inlet flange 1 is 45 degree.
Embodiment 5:
Constitutionally stable gas exhaust manifold as shown in Figure 1, the present embodiment, on the basis of above-described embodiment, is arranged on the joint of arm and inlet flange 1 and the joint of arm and gathering tube 4 at described reinforced sheet 3.Reinforced sheet 3 plays and strengthens constitutionally stable effect, due to each arm, flange, gathering tube, it is structure as a whole, its structure is least stablized and is in the joint in each parts, therefore reinforced sheet is arranged on to the joint of each parts, i.e. the joint of the joint of arm and inlet flange 1 and arm and gathering tube 4.
Described reinforcement plate 6 is connected to the stage casing of mixing tube 5.Mixing tube 5 has certain length, reinforcement plate is arranged on to the stage casing of mixing tube 5, can strengthen its stability.
As mentioned above, can realize preferably the present invention.
