Description
Technical field
The utility model relates to the technical field that auto parts and components are manufactured, especially a kind of reducing outlet pipe.
Background technique
Along with expanding economy, the recoverable amount of automobile is more and more, and automobile exhaust pollution is serious, and people's health is on the hazard.Outlet pipe is as a kind of gas emission device, important parts on automobile, be installed between enmgine exhaust and baffler, make whole vent systems be flexible connection, thereby play damping noise reduction, the convenient effect of installing and extending the exhausting silencer system life-span, vehicle exhaust needs, through three-element catalytic and outlet pipe, to complete purification process out from Engine Exhaust Emission.Existing automobile exhaust pipe is all by metallic material coiling and molding, and bulk strength is not high, and using effect is bad, and corrosion resistance and thermal insulation are bad, and working life is shorter.
Model utility content
The technical problems to be solved in the utility model is: for overcoming the problem of above-mentioned existence, provide a kind of reducing outlet pipe.
The utility model solves the technological scheme that its technical problem adopts: a kind of reducing outlet pipe, comprise upper tube body and lower tube body, the integrally welded structure of upper tube body and lower tube body, upper tube body is identical with the diameter of lower tube body connecting port, upper tube body is reducing cylindrical shell, lower tube body is cylindrical tube, offers relief opening on upper tube body, is provided with suction port on lower tube body.
Further, upper tube body and lower tube body are that gapless stainless steel tube is made, and the wall thickness of upper tube body and lower tube body is identical, and wall thickness is 0.8mm～3.0mm.
Further, the inwall of upper tube body and lower tube body is provided with titanium dioxide layer, and the thickness of titanium dioxide layer is 0.6mm～1.5mm.
Further, the outside of upper tube body and lower tube body is coated with thermal-protective coating.
The beneficial effects of the utility model are, reducing exhaust pipe structure of the present utility model is simple, adopt reducing cylindrical shell and cylindrical tube to be welded, exhaust velocity is fast, be conducive to full combustion of gas in motor, reduce pollutant emission, the titanium dioxide layer of inboard wall of tube body, can effectively reduce the nitrogen oxide in vehicle emission, can reduce PM2.5 suspending particulate matter, the thermal-protective coating of tube wall can improve Safety performance, and stainless body has stronger decay resistance and withstand voltage properties, long service life.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. upper tube bodies in figure, 2. lower tube body, 3. titanium dioxide layer.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
Reducing outlet pipe as shown in Figure 1, comprise upper tube body 1 and lower tube body 2, upper tube body 1 and the integrally welded structure of lower tube body 2, upper tube body 1 is identical with the diameter of lower tube body 2 connecting ports, and upper tube body 1 is reducing cylindrical shell, lower tube body 2 is cylindrical tube, on upper tube body 1, offer relief opening, on lower tube body 2, be provided with suction port, the diameter of outlet on upper tube body 1 is greater than the suction port diameter on lower tube body 2, in the time of exhaust emissions, mass rate of emission is fast, and is conducive to oil outflow that some do not have sufficient combustion.
Upper tube body 1 and lower tube body 2 are made for gapless stainless steel tube, upper tube body 1 is identical with the wall thickness of lower tube body 2, and wall thickness is 0.8mm～3.0mm, the inwall of upper tube body 1 and lower tube body 2 is provided with titanium dioxide layer 3, the thickness of titanium dioxide layer 3 is 0.6mm～1.5mm, titanium dioxide is as photocatalyzer, can purify air, 25% to 45% nitrogen oxide in elimination vehicle emission, reduce PM2.5 suspending particulate matter, the outside of upper tube body 1 and lower tube body 2 is coated with thermal-protective coating, improve Security, stainless body has stronger decay resistance and withstand voltage properties, long service life.
Taking above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this model utility technological thought, carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to claim scope.
