Description
Technical field
This utility model is related to technology of gas pipeline field, and specially a kind of good airproof performance has the PE combustion gas of fire-proof function
Pipeline.
Background technology
China's plastic conduit have developed rapidly, and quality is improving constantly.At present, preliminarily formed with polyvinyl chloride pipe, poly- second
Plastic tube industry based on alkene (PE) pipe and polypropylene (PP-R) pipe.Wherein polyethylene (PE) pipe is due to its own unique advantage
It is widely used in building water supply, construction drainage, buried drain pipe, building and heating, gas transmission and distribution, appendix, electrician and electricity
News protection sleeve pipe, industrial pipe, agricultural pipe etc..It is mainly used in urban water supply, city gas supply and field irrigation,
Gas supply field, such as Patent Office of the People's Republic of China's Authorization Notice No. are CN205261233.U entitled " a kind of freedom from repairs gas pipeline ",
It solves pipeline maintenance this problem of difficulty well, but the fire protecting performance of pipeline could not be improved well, and and for example China is special
Sharp office Authorization Notice No. is CN20422696.U entitled " heat insulation structure of polyvinyl fuel gas pipeline ", and it is well to pipe
Road carries out being incubated and heat-insulated, but does not also note the fire protecting performance of pipeline well, for this reason, it is proposed that a kind of good airproof performance has
The PE gas pipeline of fire-proof function.
Utility model content
The purpose of this utility model is the PE gas pipeline providing a kind of good airproof performance to have fire-proof function, on solving
State the problem of the fire-proof function difference proposing in background technology.
For achieving the above object, this utility model provides following technical scheme：A kind of good airproof performance has fire-proof function
PE gas pipeline, including PE pipeline, the outer wall of described PE pipeline is socketed with sealant, and the outer wall of described sealant is socketed with fire prevention
Layer, the inner cavity top of described fireprotection layer is provided with silicon oxide layer, and the bottom of described silicon oxide layer is provided with flame-retardant layer, described fire prevention
The outer wall of layer is socketed with thermal insulation layer, the outer wall socket matcoveredn of described thermal insulation layer, and the inner cavity top of described protective layer is provided with
