Description
Technical field：
The present invention relates to heat supply, cooling, ship domain energy conveyance conduit field, and in particular to a kind of soft thermal insulating pipe repaired mouth
Connect heat-insulating pipe fitting and repaired mouth connection heat preserving method.
Background technology：
At present, the utilidor used, service pipe is substantially steel, hard plastic material, and without flexibility, outer protection tube is adopted by standard
High-density polyethylene material, flexibility is not enough, especially the small-bore pipeline of below DN150 specifications, is all to use steel pipe connecting
Connect, repaired mouth position uses outsourcing plastic cement cotton, then winds plastic band, causes a problem in that, the plastic cement cotton of pipeline connection can not be close
That closes is incubated to pipeline formation, causes truncation surface many, interface is more, heat insulation effect is not good, is entering last in real estate room
The Duan Zaocheng common people can not enjoy the high of the energy and expend achievement, and pipeline construction is coarse, and the pipe network life-span is low.
The content of the invention：
It is an object of the invention to provide a kind of soft thermal insulating pipe repaired mouth connection heat-insulating pipe fitting and repaired mouth connection heat preserving method.
Above-mentioned purpose is realized by following technical scheme：
A kind of soft thermal insulating pipe repaired mouth connects heat-insulating pipe fitting, and its composition includes：Flexible repaired mouth pipe fitting, described flexible repaired mouth pipe fitting
Two ends have a repaired mouth sleeve pipe, and described repaired mouth sleeve pipe two ends are overlapped with instrumentation tubes respectively, described flexible repaired mouth pipe fitting, described
Heat-insulation layer is separately installed between instrumentation tubes and outer protection tube, the smooth position of described sleeve pipe has two circular holes, described circular hole
Place is provided with polyurethane liquid injection device.
Described soft thermal insulating pipe repaired mouth connection heat-insulating pipe fitting, described heat-insulation layer uses polyurethane plastics foam thermal insulation material
Matter, described outer protection tube, described repaired mouth sleeve pipe use high density polyethylene (HDPE) material.
Described soft thermal insulating pipe repaired mouth connection heat-insulating pipe fitting, described instrumentation tubes, described flexible repaired mouth pipe fitting with it is outer
Uniform wall thickness and coaxial between pillar, described flexible repaired mouth pipe fitting, described instrumentation tubes caliber scope are DN15mm-
1200mm。
A kind of soft thermal insulating pipe repaired mouth connection heat-insulating pipe fitting and repaired mouth connection heat preserving method, this method comprises the following steps：
The structure used first is the polyethylene repaired mouth outer protection tube of flexible structure, with the pliability that can arbitrarily bend；
Before service pipe connection, flexible repaired mouth pipe fitting is shifted to an earlier date into installation set on utilidor, will after service pipe connection
Repaired mouth pipe fitting sleeve pipe is moved to repaired mouth position, and sleeve pipe two ends are overlapped on utilidor edges at two ends, and centre is using repaired mouth sleeve pipe
Flexible structure, nature realizes that flexible bending is connected according to repaired mouth position, then two ends lap-joint, using high temperature heater (HTH) to sleeve pipe
End is heated, and end is tightly melted with pipe end and is bonded in one, at the two ends smooth position of the sleeve pipe close to end,
Two closed circular holes are made, the polyurethane liquid of the highdensity polyurethane foams made according to pipeline specifications is injected
In thermal insulation casing, the hole for irrigating liquid is blocked using closed block, while the foaming effect of another section of observation, one
Denier finds that polyurethane foam by overfolw hole, is blocked using blocking at once, polyurethane foam is continued in repaired mouth sleeve pipe
Proceed, form highdensity insulating foam layer, through this operation, realize high heat preservation performance, and gather with extremely strong flexible
Urethane flexibility repaired mouth utilidor system.
Beneficial effect：
1. the present invention is a kind of soft thermal insulating pipe repaired mouth connection heat-insulating pipe fitting, what is mainly solved is exactly the small of below DN1200 specifications
The repaired mouth of bore utilidor, especially bend part just curved can not carry out the closed company of high density polyurethane insulation repaired mouth with curved
Connect, cause joint coating on pipeline position to close, heat insulation effect is low, pipeline life is short, human factor easily influences asking for pipeline life
Topic
2. the soft thermal insulating pipe repaired mouth connection heat-insulating pipe fitting of the present invention can realize straight length, any crooked radian, any angle
The insulation connection of turning repaired mouth, realize the optimum efficiency of flexible repaired mouth insulation connection.Improve the pipeline of heating network end
Temperature, saves energy resource consumption and exhaust emission, obtains the praise of user.
The soft thermal insulating pipe repaired mouth connection heat-insulating pipe fitting of the present invention, the structure of use is outside the polyethylene repaired mouth of flexible structure
Pillar, with the pliability that can arbitrarily bend.
The present invention is by the polyethylene repaired mouth sleeve pipe of flexible flexible structure, the high density polyurethane plastic blister of quantitative package
Foam foaming agent, have an irreversible blocking close material feeding and steam vent, according to pipeline specifications, two ends are slightly larger than outer protection tube, can covered
Move on outer protection tube surface, followed by about 150mm smooth end, it can open and take material hole and steam vent, other middle positions are complete
Portion is corrugated, the pipeline that can arbitrarily bend.
