Number line is embedded in polyurethane insulation coating, and signal wire insulation tube is cased with above signal wire, and signal wire passes through thermal shrinkage terminal cap and work
The position of steel pipe is 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 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 has completely cut off the water leakage from adjacent channel, has reduced since each segment pipe (pipe fitting) is respectively formed independent sealed
Heat (cold) loss amount of pipeline, while also improving the accuracy of pipe leakage point location.
Polyurethane insulation coating and outside in the sealing space form isolation；
Signal wire insulation tube is cased on the signal wire, the purpose is to ensure that the insulation between signal wire and working steel tube
State does not influence the leak supervision function of intelligent heat preserving pipe.
The structure of the utility model is the independent sealed anti-leakage structure in two ends of pipeline (pipe fitting)；The pyrocondensation of end
End cap material is polyethylene heat shrinking sleeve, and cladding material is radiant crosslinked polyethylene, inner layer material is sealant；Signal wire and work
The signal wire insulation tube material for making the selection of steel tube head lap position is heat-shrinkable T bush；Signal wire, which is drawn, shrinks the close of end cap position
Closure material is sealing joint strip.
The utility model is by adopting the above technical scheme: easy to operate, easy to accomplish, raw material are easy to obtain, technically
Feasible, economic effect is best；Using independent sealed anti-leakage structure, solve the problems, such as that water enters pipe insulating layer, anti-major structure
It is ruptured at outer protection tube；Simultaneously because it is independent sealed, completely cut off the water leakage from adjacent channel, improves pipe leakage point location
Accuracy；Also it can prevent from directly contacting between signal wire and steel pipe using insulating Design forming short circuit Intelligent pipe net being caused to be let out
Missing inspection examining system false alarm.
