One not subjected to pressure region, gas detector is arranged on the not subjected to pressure part of pressurized ring flat-plate III and connects with not subjected to pressure intra-zone.
Being additionally provided with guide shell, guide shell one end is connected with inlet tube, and the other end is movable end, and and outlet between leave
Gap.
Described work corrugated tube has between many groups, and operated adjacent corrugated tube by corrugated tube adapter connection.
The beneficial effects of the utility model:
The outer pressure axial type expansion joint of the band leakage monitoring function that this utility model provides, by arranging work corrugated tube
Gas detector, pressurized outer tube and pressurized ring flat-plate, form the pressurized zone and not subjected to pressure region closed, and gas detector is arranged on
In not subjected to pressure region；This expansion joint possesses non-pressure type leakage monitoring function, and detection sensitivity is high, have simultaneously compensation dosage big,
The significant advantages such as flow resistance is low, displacement counter-force is little, be particularly well-suited to working media be poisonous and harmful and inflammable and explosive, large compensation amount,
Low flow resistance, thin tail sheep counter-force tubing in；This utility model is capable of monolayer and the leakage of multilamellar external pressure corrugated tube
Monitoring, and there is the highest sensitivity, owing to corrugated tube uses external pressure straight-through structure, the wave number of corrugated tube can arbitrarily increase
And do not limited by post buckling pressure, expansion joint can realize the biggest compensation dosage, can reduce flow resistance simultaneously, reduce position
Move the effect of counter-force.

Detailed description of the invention
Below in conjunction with detailed description of the invention, this utility model is further elaborated.
As shown in the figure: the outer pressure axial type expansion joint of a kind of band leakage monitoring function, outside including gas detector 9, pressurized
Pipe 7, pressurized ring flat-plate I 2, pressurized ring flat-plate II 4 and pressurized ring flat-plate III 8, pressurized ring flat-plate II 4 and pressurized ring flat-plate III 8 are separately positioned on work
Making the two ends of corrugated tube 5, the two ends of pressurized outer tube 7 are connected with pressurized ring flat-plate I 2 and pressurized ring flat-plate III 8 respectively, pressurized ring flat-plate I 2,
The pressurized zone of closing, import is formed between outside pressurized ring flat-plate II 4, pressurized ring flat-plate III 8, pressurized outer tube 7 and work corrugated tube 5
Pipe 1 is connected with pressurized ring flat-plate I 2, and outlet 10 one end is connected with pressurized ring flat-plate II 4, and the other end is movable end, and with pressurized ring flat-plate
III 8 radially exist gap, can axially opposed slide between outlet 10 and pressurized ring flat-plate III 8, pressurized ring flat-plate II 4, work
Forming a not subjected to pressure region inside corrugated tube 5, between pressurized ring flat-plate III 8 and outlet 10, gas detector 9 is arranged on pressurized
The not subjected to pressure part of ring flat-plate III 8 also connects with not subjected to pressure intra-zone.
One end of work corrugated tube 5 is connected with pressurized ring flat-plate II 4, and the other end is connected with pressurized ring flat-plate III 8；Work corrugated tube
5 can be one group, it is also possible to be many groups, if many groups are then linked together by corrugated tube adapter 6.Inlet tube 1 and pressurized
Ring flat-plate I 2 is connected, and pressurized outer tube 7 is connected with pressurized ring flat-plate I 2 and pressurized ring flat-plate III 8, then, outside pressurized ring flat-plate I 2, pressurized
Pipe 7, pressurized ring flat-plate II 4, work form being subject to of a closing between the outside of corrugated tube 5, corrugated tube adapter 6, pressurized ring flat-plate III 8
Intermediate pressure section.Outlet 10 one end is connected with pressurized ring flat-plate II 4, and the other end is movable end, and is radially leaving with pressurized ring flat-plate III 8
A small amount of gap, can axially opposing slide between outlet 10 and pressurized ring flat-plate III 8, to compensate pipeline tensile and compress position
Move.
Pressurized ring flat-plate II 4, work between the inner side of corrugated tube 5, corrugated tube adapter 6, pressurized ring flat-plate III 8, outlet 10
Between formed a not subjected to pressure region.Not subjected to pressure part at pressurized ring flat-plate III 8 arranges gas detector 9, non-by detecting this
The change of medium composition in pressurized zone, i.e. may determine that whether work corrugated tube 5 leaks.
Guide shell 3 one end is connected with inlet tube 1, and the other end is movable end, and and outlet 10 between leave a small amount of gap,
Working media is entered in expansion joint pressurized zone by this gap, and guide shell 3 can make working media smooth flow, to reduce stream
Resistance, it is possible to avoid the working media impact to corrugated tube.
Owing to leakage monitoring of the present utility model is to be carried out by the change of medium composition in not subjected to pressure region, it not logical
Excess pressure change is carried out, even if corrugated tube there occurs a small amount of leakage, it is also possible to detecting, therefore, detection sensitivity is the highest.
Owing to corrugated tube uses external-compression type structure, the wave number of corrugated tube can arbitrarily increase and not limited by post buckling pressure
System, therefore expansion joint can realize the biggest nose balance amount, and the axial rigidity of expansion joint is the lowest simultaneously, it is possible to reaches to reduce
The effect of displacement counter-force.
