Liner, the ladder that corrosion-proof lining is located at the ring flange of two cooperations is intraoral, and the inwall of each pipeline body scribbles epoxy anticorrosion
Layer, the outer wall of each pipeline body scribbles frost retarding layer.
After being connected with each other between pipeline body by respective ring flange, by bolt to entering between two pipeline monomers
Row is fixed, and corrosion-proof lining seals the coupling part between pipeline body, prevents air from entering corrosion pipeline, it is ensured that pipeline monomer
Service life；
The setting of heat-insulation layer on pipeline body outer wall, the adverse circumstances with good heat insulation effect, in the winter time low temperature
In, the sewage in pipeline will not freeze, and can normally use, and not influenceed by extraneous low temperature environment, and this structure has very strong
It is practical.
Further, the corrosion-proof lining is made of polytetrafluoroethylmaterial material.
Further, ladder mouthful end face shape in curved surface on the ring flange, curved surface is the big wavy surface of surface area.
The liner that polytetrafluoroethylmaterial material is made is as the corrosion-proof lining of tube body, and polytetrafluoroethylmaterial material has high anti-corrosion
Property, it is the world today's most corrosion-resistant material；
The pipeline opening of ring flange end is set to stepped ladder mouthful simultaneously, corrosion-proof lining is that contact surface is in curved surface
Mutual extruding contact, therefore make tube body can be formed when being mutually butted closely, contact surface it is big, rigid anti-corrosion connect,
Not only preserving and sealing effect is good, and anti-corrosion life increases.
Further, frost retarding layer includes prime coat, the aqueous inorganic zinc-rich enamelled coating being successively set on pipeline body outer wall
And heat-insulation layer.
Further, the heat-insulation layer includes inner thermal insulating layer and external thermal insulation, and inner thermal insulating layer is aluminium silicate wool layer, described
If external thermal insulation is made up of some glass layers and dried layer aluminium foil layer.
Further, described epoxy anticorrosion layer is that thickness is 0.12~1.56mm.
The beneficial effects of the utility model are as follows：
1st, the utility model is simple in construction, reasonable in design, is connected with each other between pipeline body by respective ring flange
Afterwards, by bolt to being fixed between two pipeline monomers, corrosion-proof lining seals the coupling part between pipeline body, prevents
Only air enters corrosion pipeline, it is ensured that the service life of pipeline monomer；The setting of heat-insulation layer on pipeline body outer wall, with very
Good heat insulation effect, in the winter time in the adverse circumstances of low temperature, the sewage in pipeline will not freeze, and can normally use, not by the external world
The influence of low temperature environment, this structure has very strong practical.
2nd, the liner that polytetrafluoroethylmaterial material is made is as the corrosion-proof lining of tube body, and polytetrafluoroethylmaterial material has high anti-
Corruption, is the world today's most corrosion-resistant material, while the pipeline opening of ring flange end is set to stepped ladder mouthful,
Corrosion-proof lining be contact surface it is in curved surface mutual extruding contact, therefore make tube body can be formed when being mutually butted closely, contact
Face is big, rigid anti-corrosion connection, and not only preserving and sealing effect is good, and anti-corrosion life increases.
