Description
Technical field
The utility model belongs to gas pipeline leakage monitoring technical field more particularly to a kind of gas pipeline based on DAS
Leakage monitoring simulator.
Background technique
With the development of the social economy, the demand to clean energy resource is increasing, the transport agent of traditional natural gas
Highway, railway and ship, part energy will consume in the movement of carrier, especially need empty wagons, clean ship return without
It can continuative transport.And the carrier of pipeline is pipeline itself, pushes directly on natural gas by discharge pressure and around the clock flows
It is dynamic, therefore natural gas line takes up an area less, investment is small, construction is fast, fortune oil mass is big, management automation easy to accomplish.
Natural gas line is imbedded in underground, is closed in pipeline and is isolated from the outside, one side pipeline is to environment
Pollute it is small, it is on the other hand safe and reliable, not vulnerable to the interference of traffic above-ground, weather and other natural conditions variation and artificial broken
It is bad.Therefore natural gas line is often monitored without leak condition of the direct monitoring device to pipeline, once occur natural
Gas leakage accident directly results in the waste of resource and the personal safety as well as the property safety of surrounding people, or even sets off an explosion and bring huge damage
It loses.Therefore the concern to natural gas line leakage monitoring increasingly by society.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of gas pipeline leakage monitoring simulation based on DAS
Device is realized and sufficiently simulates pipe leakage under safe condition, obtains what DAS when gas pipeline leakage leaked pipe natural gas
Acoustic vibration signal is reported situations, and is leaked real-time monitoring for natural gas line and is provided strong test support.
The technical solution of the utility model is：
A kind of gas pipeline leakage monitoring simulator based on DAS, including the optical cable along gas pipeline parallel lay-up, with
Optical cable connected DAS device and computer；It further include high pressure tank, the metal connecting tube being connected with high pressure tank is described
The other end insertion ground of metal connecting tube, which is located at gas pipeline top and is connected to gas, releases head, on the metal connecting tube
Equipped with pressure-regulating valve.
Compared to the prior art, the technical program is logical based on high pressure tank control leak pressure and pressure relief opening diameter
The design for simulating natural gas leaking, devises monitoring simulator, can be real in complicated natural gas leaking monitoring application environment
Reality tests simulation monitoring.It can be released head according to experiment demand, the gas that replace different pressure relief opening diameters in the technical program.
Based on above scheme, the utility model is also made that following improvement：
Further, the release vertical range of head and optical cable of the gas is 0.5-1.0m.This improvement project is because of big portion
Subtube is 0.5-1.0m with the optical cable fore-and-aft distance with pipeline laying, is put into this position and can effectively simulate pipe gas head of releasing
Road leakage.
Further, harmless pollution-free gas of the storage pressure more than or equal to gas pipeline pressure in the high pressure tank
Body.In this improvement project, pipe leakage is simulated using harmless uncontaminated gases such as oxygen, nitrogen etc., is both able to achieve monitoring simulation,
It is again free from environmental pollution.
Further, the pressure-regulating valve includes dropping valve, relief valve.In this improvement project, dropping valve is used for will be high
Pressure value needed for gas pressure drops to simulation in pressure gas tank, relief valve are used to be used to monitor simulation for gas releasing.
Further, the diameter of the gas bleeder valve can be adjusted by knob.This improvement project, gas bleeder valve
Different pressure relief openings can be selected directly to carry out gas discharge, simulate the leakage monitoring of different size leakage holes according to simulation demand.
The utility model has the beneficial effects that setting leakage air pressure identical with natural gas line and leakage by the device
Practical application of the test distributed optical fiber acoustic system that pore size can be convenient in natural gas line leakage monitoring field is imitated
Fruit promotes user experience effectively to solve the visual effect of gas pipeline field monitoring simulation.
