Abstract
The utility model discloses a thermal -insulated blast pipe keeps warm, including the body, above -mentioned body outer wall parcel has hyperoxia silicon inlayer, ceramic fibre middle level, hyperoxia silicon skin, above -mentioned hyperoxia silicon inlayer, ceramic fibre middle level, the outer constitution three -layer sandwich of hyperoxia silicon. The beneficial effects of the utility model reside in that, this blast pipe both can keep the exhaust system temperature, can reduce the heat radiation of starting the machinery room to receive again.
Description
Technical field
The utility model relates to automobile exhaust technical field, particularly relates to a kind of insulation outlet pipe.
Background technique
After state four standard carried out by diesel engine, after-treatment system major part adopts SCR system (selective catalytic reduction system operating), adopt in the process of SCR system and need to use urea liquid, but the freezing point of urea liquid is-11 DEG C, so when temperature can crystallization lower than urea liquid time this.Existing SCR system diesel-oil vehicle is when the area that temperature is lower uses, and such as the northern area of China, likely there will be vent systems crystallization.In addition, because existing exhaust insulation effect is poor, motor vehicle exhaust hull-skin temperature is higher, makes engine compartment be subject to significant thermal radiation, is unfavorable for that engine bin dispels the heat.
Model utility content
The purpose of this utility model is to provide a kind of insulation outlet pipe, and this outlet pipe both can keep exhaust system temperature, can reduce again the thermal radiation that engine bin is subject to.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of insulation outlet pipe, comprise body, above-mentioned tubular body outer wall is enclosed with hyperoxia silicon internal layer, ceramic fiber middle level, hyperoxia outer silicon, and above-mentioned hyperoxia silicon internal layer, ceramic fiber middle level, hyperoxia outer silicon form three-layer sandwich structure.
Preferably, above-mentioned hyperoxia outer silicon outer wall is also enclosed with wrapping layer, and the thickness of above-mentioned wrapping layer is 10mm-15mm.
Compared with prior art, the outlet pipe tube wall that the utility model provides is enclosed with hyperoxia silicon internal layer, ceramic fiber middle level, hyperoxia outer silicon, and three layers form sandwich structure, considerably increase heat insulating effect.
The beneficial effects of the utility model are, this outlet pipe both can keep exhaust system temperature, can reduce again the thermal radiation that engine bin is subject to.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Wherein, body 1, hyperoxia silicon internal layer 2, ceramic fiber middle level 3, hyperoxia outer silicon 4, wrapping layer 5.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
The technological scheme that the utility model is specifically implemented is:
A kind of insulation outlet pipe, comprise body 1, above-mentioned tubular body 1 outer wall is enclosed with hyperoxia silicon internal layer 2, ceramic fiber middle level 3, hyperoxia outer silicon 4, and above-mentioned hyperoxia silicon internal layer 2, ceramic fiber middle level 3, hyperoxia outer silicon 4 form three-layer sandwich structure.
Preferably, above-mentioned hyperoxia outer silicon 4 outer wall is also enclosed with wrapping layer 5, and the thickness of above-mentioned wrapping layer 5 is 10mm-15mm.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
