In figure：Protection pipe 1, feed pipe 2, return pipe 3, the first insulating layer 4, the second insulating layer 5.
Specific embodiment
The embodiment of technical solutions of the utility model is described in detail below in conjunction with attached drawing.Following embodiment is only
For clearly illustrating the technical solution of the utility model, therefore example is only used as, and cannot this practicality be limited with this
Novel protection domain.
Fig. 1 shows the cross section structure schematic diagram of heat supply pipeline according to the present utility model.As shown in Figure 1, the heating tube
Including feed pipe 2, return pipe 3,1 and first insulating layer 4 of protection pipe, a spacing is spaced between the feed pipe 2 and return duct for road
From, and be set in the protection pipe 1 jointly, first insulating layer 4 is filled in the protection pipe 1 and feed pipe 2 and return water
In gap between pipe 3.Wherein, feed pipe 2 is located at the lower part of return pipe 3.
Protection pipe 1 is made of hard material, such as tubular structure is made by hard polyethylene material.In the embodiment, institute
It states feed pipe 2 and is less than DN400 with 3 caliber of return pipe, material is ordinary carbon steel.
Further, the outer wall of the feed pipe 2 is equipped with the second insulating layer 5.Second insulating layer 5 select have compared with
The material of small thermal conductivity factor is made, such as is made of fumed silica.The thermal conductivity factor of second insulating layer 5 is about 0.007W/
M.K can maximumlly reduce heat and scatter and disappear.The thickness of second insulating layer 5 is 5-7mm, such as 6mm.
Heat supply pipeline in the present embodiment uses the lower parallel arrangement for last time.Specifically, the feed pipe 2, return
The kernel of section line of water pipe 3 and protection pipe 1 respectively in the vertical direction coincides with one another, feed pipe 2 be located at return pipe 3 just under
Side.Since 2 temperature of feed pipe is relatively high, easy unstability of expanding with heat and contract with cold, such arrangement, by return pipe 3 conduct oneself with dignity constraint and
Whole tube bank limitation, 2 overall stability of feed pipe are more preferable.
Heat transfer between feed pipe 2 and return pipe 3 in order to prevent needs interval one between feed pipe 2 and return pipe 3
Set a distance, the minimum separation distances a between the outer wall of second insulating layer 5 and the outer wall of return pipe 3 are 25-35mm.
First insulating layer 4 is made of polyurethane foam, i.e., is filled in feed pipe 2,3 and of return pipe by polyurethane foam
In the gap formed between protection pipe 1, the first insulating layer 4 is formed.
The distance between the bottom of second insulating layer 5 of feed pipe 2 and the inner bottom wall of protection pipe 1 b are 10-15mm, such as
12mm.The distance between the top of second insulating layer 5 and the inner roof wall of protection pipe 1 c are 20-35mm, such as 28mm.
In use, stating one end connection heat-exchange unit water supply side of feed pipe 2, the other end connects heat supply pipeline in the embodiment
Connect user's influent side, one end connection user's water outlet side of the return pipe 3, other end connection heat-exchange unit return water side, feed pipe 2
Closed loop is formed with return pipe 3.Heating agent is hot water, and 2 supply water temperature of feed pipe is 70 DEG C~50 DEG C, 3 return water temperature of return pipe
It is 40~50 DEG C.
Heat supply pipeline in the application so that feed pipe 2 and the integral structure of 3 concentrated setting of return pipe have both preferable
Heat preservation and protection effect, and integrated design causes the compact-sized of heat supply pipeline, and return pipe 3 is supplied individually with traditional
System of laying is compared, and is realized single tube laying, is reduced heating network arrangement space, and tube top thickness of earth-fill cover is reduced to 1.0m,
It is small with excavation area, the advantages that construction space is small, low engineering cost.
