Description
Technical field
The present invention relates to a kind of pipeline anti-leakage structures, are specifically related to the effective independent sealed antiseepage drain junction of intelligent heat preserving
Structure.
Background technology
Direct-burried intelligent heat preserving pipeline in the process of running, can occur insulating layer water inlet phenomenon, cause to protect due to various reasons
Temp effect reduction, line leakage thrashing.
Especially when working steel tube leaks, the water with pressure will be along insulating layer and working steel tube and outer protection tube
Contact spread towards pipe ends, the distance of diffusion is often as high as tens meters, rice even up to a hundred, causes the insulating layer of insulating tube
Failure, it is serious can cause reveal section insulating tube integrally scrap;Meanwhile it is greatly tired to judge that leakage point position is caused to user
It is difficult.
Problem above Producing reason, have to be polyurethane prefabricated direct-buried thermal insulation pipe function, but by itself
Caused by architectural characteristic, it can prevent external underground water from entering insulating layer, but cannot bear inside more than 0.02MPa pressure
Water.When working steel tube leaks, the water with pressure enters the space that insulating layer, working steel tube and outer protection tube are formed
Afterwards, random motion can be carried out, the small water of resistance where is just where gone.And since insulating layer is an overall structure, do not allow
It is easily destroyed, the adhesion strength of own is higher than working steel tube and the adhesion strength of insulating layer and outer protection tube and insulating layer, simultaneously
Pressure is born inside outer protection tube to be expanded, thus water will along insulating layer and the contact of working steel tube and outer protection tube towards
Pipe ends are spread, and cause outer protection tube to rupture until outer protection tube cannot withstand hydraulic pressure.And for the polyurethane of band signal line
Insulating tube will not only consider the above problem, it is also necessary to consider how to prevent from being in direct contact to form short circuit between signal wire and steel pipe
The problem of.
Invention content
In view of the prefabricated direct-buried intelligent heat preserving pipeline of polyurethane will appear in use more than problem, the present invention research and development
Go out a kind of effective independent sealed anti-leakage structure of the intelligent heat preserving that can be solved the above problems, reduces pipe-line maintenance expense.
To achieve the goals above, the technical solution adopted in the present invention is:The effective independent sealed antiseep of intelligent heat preserving
Structure, including working steel tube, epoxy coating, sealing joint strip, signal wire, polyurethane insulation coating, outer protection tube, thermal shrinkage terminal cap, signal
Line insulation tube, bosom are working steel tube, and working steel tube two ends outer surface is equipped with epoxy coating, working steel tube outside equipped with outer
Pillar, is polyurethane insulation coating between working steel tube and outer protection tube, and pipe ends are respectively equipped with thermal shrinkage terminal cap, thermal shrinkage terminal cap both ends
The confined space to form an entirety, signal wire are mutually overlapped with the epoxy coating of working steel tube end outer surface and outer protection tube respectively
It is embedded in polyurethane insulation coating, signal wire insulation tube is cased with above signal wire, signal wire passes through thermal shrinkage terminal cap and working steel tube
Position be equipped with sealing joint strip.
Further, sealing joint strip is arranged between signal wire insulation tube and epoxy coating, and signal wire uses insulation tube packet
The upper surface of cover and be fixed on sealing joint strip, sealing joint strip plays sealing and heat-insulated effect, signal wire insulation tube and work simultaneously
Make steel pipe contact surface to be thermally shielded using sealing joint strip, prevent insulation tube in the construction process temperature it is excessively high cause carbonization cause letter
Number line and working steel tube contact occur failure of insulation and cause Intelligent pipe net leakage monitoring system false alarm.
Signal wire is drawn position from thermal shrinkage terminal cap and is sealed using fluid sealant, prevents water from entering in pipe insulating layer.
Thermal shrinkage terminal cap both ends mutually overlap to form one with the epoxy coating of working steel tube end outer surface and outer protection tube respectively
Whole confined space, the signal wire of extraction are attached at repaired mouth, ensure that the continuity of signal wire.The insulating layer of pipeline
Once water inlet, due to each segment pipe(Pipe fitting)It is respectively formed independent sealed, has completely cut off the water leakage from adjacent channel, reduced
The heat of pipeline(It is cold)Loss amount, while also improving the accuracy of pipe leakage point location.
Polyurethane insulation coating in the sealing space forms isolation with outside;
Signal wire insulation tube is cased on the signal wire, the purpose is to ensure that the insulation shape between signal wire and working steel tube
State does not influence the leak supervision function of intelligent heat preserving pipe.
The structure of the present invention is in pipeline(Pipe fitting)The independent sealed anti-leakage structure of two ends;The thermal shrinkage terminal cap of end
Material is polyethylene heat shrinking sleeve, and cladding material is radiant crosslinked polyethylene, inner layer material is fluid sealant;Signal wire and work steel
The signal wire insulation tube material that pipe end lap position is selected is heat-shrinkable T bush;Signal wire draws the sealing material for shrinking end cap position
Material is sealing joint strip.
The present invention uses above-mentioned technical proposal:Easy to operate, easy to implement, raw material are easy to obtain, technically feasible,
Economic effect is best;It using independent sealed anti-leakage structure, solves the problems, such as that water enters pipe insulating layer, prevents from causing outer shield
Tracheal rupture;Simultaneously because it is independent sealed, completely cut off the water leakage from adjacent channel, improves the accurate of pipe leakage point location
Property;Also use insulating Design that can prevent from being in direct contact between signal wire and steel pipe forming short circuit and causing Intelligent pipe net leak detection
System false alarm.
