Purpose, inorfil are enclosed between single side silica gel glass-fiber-fabric layer, will not spill.
Preferably, the density of the inorganic fibre mat is 110kg/m3~130 kg/m3, good effect of heat insulation.
Preferably, the constraint structure between heat-insulated cover body by high temperature resistant sew sewer in conjunction with, use the longevity
Life length.
Preferably, the side of the heat-insulated cover body is equipped with sidebody piece structure, better fixation, coating function are played.
Preferably, the sidebody piece structure is equipped with through-hole, carried out on rod piece for passing through for pipeline, or using protheca
It is fixed.
Preferably, it is described constraint structure include set on heat-insulated cover body side velcro, be set to heat-insulated cover body it is another
The fixed ring corresponding with velcro of side, by velcro around being clung again after fixed ring when constraint.
Preferably, the fixed ring is fixed on heat-insulated cover body by fixinig plate.
Preferably, being set on each fixinig plate there are two fixed ring, velcro will not be relaxed around the height of intensity later.
Compared with prior art, the utility model has the following beneficial effects: providing a kind of for automobile exhaust system
Flexible heat shield, structure is simple, easy to assembly, at low cost；Using the structure of flexible deformable, different structure can adapt to
Exhaust apparatus, while occupied space is few when storing transport.
