一种带保温功能的排气管
摘要：
一种带保温功能的排气管，由内至外依次包括排气管、保温层、绑带层与保护层，所述保温层的厚度大于排气管的厚度，排气管的厚度大于保护层的厚度，所述保护层的外表面为波浪型的凹凸结构，其制造方式为滚花工艺，所述凹凸结构包括位于波峰的凸起部、位于波谷的凹陷部与中间部，中间部的上端与凸起部相连接，中间部的下端与凹陷部相连接，中间部的中部上近凸起部的部位开设有内陷槽，该内陷槽的内扩弧度大于中间部的内扩弧度。本设计不仅能够保持排气管内的温度，保温效果较强，而且能确保产品的外观平整，能增强结构强度。
摘要（英）：

The utility model provides a take blast pipe of heat preservation function, from interior to exterior in proper order includes blast pipe, heat preservation, bandage layer and protective layer, the thickness of heat preservation is greater than the thickness of blast pipe, and the thickness of blast pipe is greater than the thickness of protective layer, the surface of protective layer is the concave -convex structure of wave type, and its manufacture is annular knurl technology, concave -convex structure is including being located the bellying of crest, the depressed part that is located the trough and intermediate part, and the upper end of intermediate part is connected with the bellying, and the lower extreme of intermediate part is connected with the depressed part, and the groove of caving in has been seted up at the position of nearly bellying on the middle part of intermediate part, expands the radian in the groove of should caving in and is greater than the intermediate part and expands the radian in. This design not only can keep the temperature in the blast pipe, and the heat preservation effect is stronger, can ensure moreover that the outward appearance of product is leveled, can strengthen structural strength.
