Description
Technical field
The utility model belongs to direct-buried pipe technical field, and in particular to a kind of Large Diameter Pipeline prefabricated direct-buried thermal insulation pipe.
Background technique
Prefabricated direct-buried thermal insulation pipe is widely used in the transmission pipeline network of liquid, gas, chemical pipeline heat insulating work, petroleum, chemical industry,
Central heating network, ventilating duct of central air conditioner, municipal works etc., therefore Insulation during transportation is particularly important,
Often there is the case where cannot fitting closely between insulating layer and service pipe in conventional Insulation, to will affect heat preservation effect
Fruit, this outer heat insulation layer both ends is as have water penetration, to influence the heat insulation effect of insulating layer.
Utility model content
A kind of Large Diameter Pipeline prefabricated direct-buried thermal insulation pipe is provided the purpose of the utility model is to overcome the deficiencies in the prior art, this
Utility model has good thermal insulation property, and insulating layer both ends of the surface are provided with waterproof layer, and water penetration has effectively been avoided to influence to protect
Temp effect.
The technical solution of the utility model is as follows: a kind of Large Diameter Pipeline prefabricated direct-buried thermal insulation pipe, including Large Diameter Pipeline instrumentation tubes, institute
It states and is disposed with insulating layer from the inside to the outside on the outside of Large Diameter Pipeline instrumentation tubes, uniformly arranges along Large Diameter Pipeline instrumentation tubes centerline direction
Strap, reflecting layer and outer protection tube, the insulating layer and reflecting layer both ends of the surface are coated with waterproof layer.
Preferably, the insulating layer center is aerogel blanket, and the aerogel blanket is vertically disposed with polyurethane foaming layer.
Preferably, the reflecting layer is aluminium foil glass fiber fabric.
Preferably, the waterproof layer uses flexible waterproof material.
Preferably, the outer protection tube is metal protection set or polyethylene protective case.
Preferably, the adjacent strap arrangement spacing is 1-1.5m.
The utility model has the beneficial effects that
(1) insulating layer center is aerogel blanket, aerogel blanket polyurethane foaming layer setting up and down, three layers of insulation construction, guarantor
Temp effect is significant；
(2) insulating layer outer wall is fixed using strap, is guaranteed accurate between insulating layer and Large Diameter Pipeline work pipe outer wall
Fitting increases heat insulation effect；
(3) insulating layer and reflecting layer both ends of the surface are coated with waterproof layer, and insulating tube junction is effectively avoided to have water penetration
Influence heat insulation effect.
In short, the utility model has good thermal insulation property, and insulating tube junction can be effectively avoided to have water penetration shadow
Ring heat insulation effect.

Foaming layer 22, three layers of insulation construction, heat insulation effect is significant, and furthermore the inside of aerogel blanket 21 80% is the above are air, and light weight,
Do not increase the weight of insulating tube, the reflecting layer 4 is aluminium foil glass fiber fabric, can the effective heat that gives out of reflective thermal-insulating layer 2, heat preservation
2 outer wall of layer are fixed using strap 3, and the adjacent strap 3 arranges that spacing is 1-1.5m, be effectively ensured insulating layer 2 with
Accurate fitting between 1 outer wall of Large Diameter Pipeline instrumentation tubes, increases heat insulation effect, and the insulating layer 2 and 4 both ends of the surface of reflecting layer are coated with anti-
Water layer 6, the waterproof layer 6 is between outer protection tube 5 and Large Diameter Pipeline instrumentation tubes 1, and waterproof layer 6 uses flexible waterproof material, effectively
Insulating tube junction is avoided to have water penetration to influence heat insulation effect, the outer protection tube 5 covers for metal protection or polyethylene protective case, can
5 material of oversheath is reasonably selected according to Land Environment.
Although the utility model is described in detail with reference to the foregoing embodiments, come for those skilled in the art
Say, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic into
Row equivalent replacement, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all
It is included within the scope of protection of this utility model.
