Abstract
The utility model discloses a fire-retarding, heat-insulating and noise-reducing exhaust pipe of an internal combustion engine. The fire-retarding, heat-insulating and noise-reducing exhaust pipe comprises a metal pipe body, of which the external surface is sequentially coated with a heat-insulating layer and a stainless steel plate layer or a stainless steel wire mesh layer. For facilitating installation, maintenance and shock-absorption, the middle section of the metal pipe body is of a corrugated pipe structure. An asbestos plate layer is arranged between the heat-insulating layer and the stainless steel pipe plate or the stainless steel wire mesh layer. A pipe nozzle of the metal pipe body is provided with a connecting flange plate. After the technical scheme is adopted, the fire-retarding, heat-insulating and noise-reducing exhaust pipe of the internal combustion engine can be used for effectively lowering the temperature of an engine exhaust pipe from inside to outside and from about 500 DEG C to below 180 DEG C to play a good role in fire retarding, heat insulation and noise reduction. The outermost layer of the exhaust pipe is the stainless steel plate layer or the stainless steel wire mesh layer, so that the deformation and crushing of an internal heat-insulating layer are avoided and the service life of the exhaust pipe is prolonged greatly. Meanwhile, the attractive appearance and the convenience in cleaning are achieved.
Description
Technical field
The utility model relates to explosive motor, especially relates to internal-combustion engine fire-proof and thermal-insulation noise-reducing exhaust pipe.
Background technique
Explosive motor (DENG, petrol engine) is widely used in transportation and communication.Along with the development of society and the progress of science and technology, the output power that is used for the vehicle explosive motor is increasing.Because the temperature that the EGT that the internal combustion engine exhaust gas mouth is discharged generally about 500-700 ℃, causes outlet pipe generally about 500 ℃, causes vehicle generation dieseling to take place frequently therefrom, brings threat for people's the security of the lives and property., must isolate for this reason,, prevent that electric wire and oil pipe from meeting high temperature and producing the distortion initiation fire that wears out to reduce internal combustion engine exhaust gas pipe peripheral temperature to the cooling of preventing fires of explosive motor outlet pipe.At present, taking is the mode of outlet pipe with asbestos cloth or composite material Apparatus for strapping packages, but asbestos cloth or composite material easy deformation or rot under high-temperature baking; Need the replacing of tying up repeatedly; Effect is undesirable, and keeps in repair, changes inconvenient, simultaneously also not attractive in appearance.
Summary of the invention
The utility model purpose is to provide a kind of internal-combustion engine fire-proof and thermal-insulation noise-reducing exhaust pipe of safe and reliable, long service life.
For realizing above-mentioned purpose, the utility model can be taked following technical proposals:
The described internal-combustion engine fire-proof and thermal-insulation of the utility model noise-reducing exhaust pipe comprises the metal body, is coated with thermal insulating warm-keeping layer and stainless steel flaggy or stainless steel stratum reticulare successively at said metal tube external surface.
For the ease of installation and maintenance and damping, the stage casing of said metal body is a bellows structure.
Between said thermal insulating warm-keeping layer and stainless steel flaggy or stainless steel stratum reticulare, be provided with the asbestos flaggy.
Mouth of pipe place at said metal body is provided with mounting flange.
After the utility model advantage is to adopt technique scheme, effectively from the inside to the outside, drop to below 180 ℃ by about 500 ℃, play the effect of good fire-proof and thermal-insulation noise reduction the engine exhaust pipe temperature.Because the outlet pipe outermost surface is stainless steel flaggy or stainless steel stratum reticulare, avoided the distortion of inner insulating layer, powder to rot, improved working life greatly.Beautiful shape, the convenient cleaning have also been improved simultaneously.
