It is low, but on-line checking can not be realized, because detection ball drifts about in pipe with medium, the pipeline of larger caliber is only applicable to, easily
Generation such as blocks, stopped transport at the accident, and detects that ball is expensive, and operating cost is higher；Second class is by directly detecting leakage
The pipe outside detection method of leakage detection and location realized be present in material, mainly including distribution type fiber-optic, cable, special cables etc., this
Class method is very sensitive, has preferable effect for gentle let out of Small leak, but price and construction cost are all higher, and being broken at one will
Whole monitoring system is caused to fail；4th class is the outside leak detecting based on operational factors such as pipeline pressure, flow and temperature, it
On-line checking can be realized, and construction and maintenance are all more convenient, are the main directions of current pipeline leakage testing and Position Research
One of.This kind of method mainly includes the method based on suction wave, based on the method for sound wave, the method based on transient flow and base in pipe
In method of model etc..In this kind of method, because negative pressure wave method is without complicated model building for pipeline, for more than 1.5% total flow
Accident release, can accurately identify leakage and precise positioning；Because suction wave caused by minute leakage is after long range is transmitted
Decay is serious, and pressure transmitter is insensitive to its, for minute leakage this method DeGrain, often fails to report.Therefore
Need a kind of new Monitoring Pinpelines structure.
