Layer.
Further, the heat-insulated body sandwich construction also includes outer protection network.
Further, the trend of the elbow part and straight-tube portion along discharge duct is divided into some sections；Pass through suture
The description of parcels separated along axis is formed, and after being wrapped on discharge duct, exhaust is fastened on by fastener formation
The insulation construction being brought into close contact on the outside of pipeline and with discharge duct.
Further, described matrix layer uses nanometer micropore heat-insulating material, including nano silicon aerogel blanket.
Further, the inner thermal insulating layer uses high-temperature fibre cloth, including basalt fiber cloth, carbon cloth and glass
Fiber cloth；The interior protection network uses metal protection silk screen, including 304 stainless steel cloths, alloy silk screen and wire netting；It is described outer
Thermal insulation layer uses high-temperature fibre cloth, including basalt fiber cloth, carbon cloth and glass fabric.
Further, the outer protection network uses metal protection silk screen, including 304 stainless steel cloths, alloy silk screen and iron
Silk screen.
Further, the fastener is connecting pin fixed structure；Or extension spring is connected structure.
Further, the connecting pin material is non-corrosive high-temperature alloy material.
The beneficial effects of the utility model are：Made using the nanometer micropore such as nano silicon aerogel blanket heat-insulating material
For base layer, thermal conductivity factor is low, and effect of heat insulation is 2-5 times of traditional insulation materials, and thickness is only three point one of traditional material, laminating
The design of formula flexible cambered-surface is more fitted with pipeline cuts off the space of heat losses, adds set internal layer surface and the effective of pipe outer wall connects
Contacting surface is accumulated, and reduces noise and vibrations, it is to avoid resonance during engine operation caused by the shell wall with set internal layer space.While by
It is undesirable using sewing machine sewing effect in prior art to nanometer micropore heat-insulating material such as nano silicon aerogel blanket,
Sew insecure and easy broken string, the sewing problems of the design solution of segmented, and saving sewing time, improve production and peace
Efficiency is filled, production cost is reduced.
