Embodiment
Utility model is described in detail with reference to the accompanying drawings and examples.
As shown in Figure 1 and Figure 2, the temperature-sensitive leak-checking apparatus provided by the utility model for having warm medium pipeline includes：Fix respectively
There are the warm outer wall both sides of medium pipeline 1 and per side each along more guarantors for there are the warm flow direction of medium pipeline 1 head and the tail sequentially to connect
Protecting pipe 2, for connecting the protection sleeve pipe jointing 5 of adjacent two protection sleeve pipes 2, it is respectively arranged in both sides protection sleeve pipe 2
Two temperature sensing optical cables 4, be connected respectively with two ends of temperature sensing optical cable 4 signal welding device（It is not shown）.
Protection sleeve pipe 2 is by fixed grooved ring 3 with there is warm medium pipeline 1 to fix.Signal welding device realizes temperature field on the spot
Data acquisition and processing (DAP) and complete data transfer.
In practice of construction, the protection sleeve pipe 2 of pre-buried temperature sensing optical cable 4, it is together segmented lower dress with great-jump-forward construction pipeline,
Inspection-pit is reserved in the construction area of the pipeline of segmentation.To ensure the needs of the follow-up air-blown installation of temperature sensing optical cable 4, inspection-pit it
Between distance ensure within 500m.The size of protection sleeve pipe 2 and material selection external diameter 8mm, thickness 1mm pipe in polishing it is stainless
Steel pipe, pipeline outer wall both sides are pre-installed in by fixed grooved ring 3, the deadweight and construction to reduce because of protection sleeve pipe 2 backfill thing
Weight is acted on the pressure of protection sleeve pipe 2, and the fixed installation site distance of grooved ring 3 has warm minus 20 degree of the central horizontal face of medium pipeline 1
With minus 160 degree, i.e., fixed grooved ring 3 and having the virtual link line of the warm cross-section center of medium pipeline 1 and have warm medium where it
The angle between horizontal plane where the center of pipeline 1 is 20 degree, and the distance between adjacent fixation annular groove 3 is less than or equal to
0.5m。
The utility model completes the fixed grooved ring base of annular groove 3 and being fixedly connected for the tube wall of pipeline 1 using welding procedure.
As shown in figure 3, the protection sleeve pipe 2 of adjacent sectional completes sectionalised protection sleeve pipe 2 using protection sleeve pipe jointing 5
Splicing.Wherein, two sections of protection sleeve pipes 2 in reserved inspection-pit wouldn't be spliced, after the completion for the treatment of integrated piping construction, from one
End starts air-blown installation temperature sensing optical cable 4, after temperature sensing optical cable 4 passes through a certain maintenance well area, then to protection sleeve pipe 2 at this
Joint splicing is carried out, until the laying of whole temperature sensing optical cable 4 finishes.Protection sleeve pipe jointing 5 uses socket weld stainless joint,
Including straight connector and union elbow, conveniently meet various field pipeline construction demand.
After temperature sensing optical cable position is fixed, by its one end access signal welding device, and at the beginning of the normal operation of integrated piping 1
Phase, collect, record the temperature value of any measuring point or owner institute particular requirement measuring point on the way of pipeline 1, the original number as the measuring point
According to such as T1（n）、T2（n）、T3（n）And T4（n）, n=1,2,3 ..., and it is equipped with geographic coordinate information.System and device is in real time to working as
Preceding data T1 ˊ（n）、T2ˊ（n）、T3ˊ（n）With T4 ˊ（n）, n=1,2,3 ... and initial data carry out contrast judgement, when pipeline 1
In normal course of operation, the temperature difference △ T1 of same observation station（n）>50 °C or T1（n）During=pipeline medium actual temperature, device is held
Row pipe leakage is alarmed.
The utility model connects adjacent protection sleeve pipe by protection sleeve pipe jointing, meets multiple-limb and big mileage pipe
The temperature sensing optical cable laying demand in road, while protect temperature sensing optical cable to be not damaged by, it is simple for structure practical
