Main line is from defeated hot main line or is directly picked out from thermal source, by with hot branch line to user's heat supply.Heat supply network caliber is true according to water force
It is fixed.In large-scale network, sometimes to ensure ductwork pressure operating mode, Central Regulation and detection parameter of heating medium, and it is dry in defeated heat
Line or defeated hot main line with hot main line junction with setting heat supply network station.Mainly according to city heat load distribution situation, block present situation, hair
Exhibition planning and geology orographic condition etc. determine, are commonly arranged to dendritic.When by multi-source heating, in order to mutually it is standby, carry
The reliability of high heat supply and flexibility, communicating pipe can be set between the defeated hot main line of each thermal source, be also arranged to ring-type.Urban district pipeline is more
It is arranged in parallel along street side and other underground utilities.The arrangement of heat supply network, which should try one's best, makes pipeline walk in thermic load center, heat supply half
Footpath is most short, city is disturbed at least, construction and operational management are convenient.Used in district heat supply networks many at present
Pipeline, situation about being corroded all occurs unavoidably after long-time use, and be incubated after many times long-time use
Poor performance so that pipeline not enough saves, therefore devises a kind of anti-corrosion energy-saving hot water pipeline of district heat supply network.
Utility model content
To achieve the above object, the utility model provides following technical scheme：A kind of district heat supply network is prevented
Rotten knot energy hot water line, including polyethylene inner layer, polyurethane heat-insulation particle is provided with the polyethylene inner layer inwall, it is described poly-
Hot melt adhesive layer is provided with the outside of ethene internal layer, aluminium foil layer is provided with the outside of the hot melt adhesive layer, is provided with the outside of the aluminium foil layer
Polyvinyl chloride layer, the polyvinyl chloride layer outside are provided with anticorrosive coat, and the anticorrosive coat includes epoxy resin internal layer, the epoxy
Phenolic resin enamelled coating is provided with the outside of resin internal layer, epoxide coal bituminous layer is provided with the outside of the phenolic resin enamelled coating.
As a kind of preferable technical scheme of the utility model, glass fibre volume is provided with the outside of the epoxide coal bituminous layer
Tissue layer.
As a kind of preferable technical scheme of the utility model, the polyethylene inner layer is internally provided with elastomer reinforcement
Muscle.
As a kind of preferable technical scheme of the utility model, the polyvinyl chloride layer is internally provided with Reduction of Students' Study Load cavity.
Compared with prior art, the beneficial effects of the utility model are：By being improved to pipe material, use more
Kind insulation material, improves the insulating power of tubing, effectively saves the loss of the energy, by setting anti-corrosion material in outer layer
Manufactured anticorrosive coat so that pipeline can be good at connecting up, and improves the service life of pipeline, is worthy to be popularized.
