Abstract
This invention features separating pipeline or container into a certain number of fluid collecting chambers and placing sensors in each room. While leakage occurs, the warner sounds alam and outputs signal to computer warning system which displays accuralate leakage position for repairing. The invention can also detect the protective layer of pipeline to find if it is in good condition.
Description
The present invention is the method whether a kind of test fluid material has leakage phenomenon, exactly is that a kind of test fluid transport pipeline or hold-up vessel of being specifically designed to is to stagnate the method for not leaking phenomenon is arranged.
At present, it is following several that the home and abroad test fluid is stored up, whether shipping unit exists the method for leakage phenomenon to have: 1, difference in flow detection method, the major defect of this method are to need higher accurate flowmeter, cost an arm and a leg, and little leakage rate is easy-to-search not, and the position of leakage point also is not easy to determine; 2, differential pressure detection method, this method are to utilize the minimizing of leak pressure to detect, and also are not easy to find so low discharge leaks; 3, infrasonic wave detection method, this method are to utilize perforation to leak and the infrasonic wave that produces detects, but because pipeline material thickness, the difference of conveying medium, leak reasons such as the aperture differs in size, and also are difficult to determine the accurate position of its leakage point.
Purpose of the present invention is the problem that occurs in the above-mentioned detection method, for people provide a kind of new test fluid transport pipeline or the method for hold-up vessel leakage.
Technical essential of the present invention is: make several continuous afflux spaces (enclosure space) in the outside of liquid conveying pipe or hold-up vessel, in each afflux space, all lay plurality of sensors, position according to each afflux space, sensor place, it is compiled into position encoded accordingly, be connected with electronic computer system with alarm by cable then, when a certain position of pipeline or hold-up vessel takes place to leak, the flowing material of its leakage contacts with sensor immediately, sensor sends out-of-order signal immediately, pass through cable, monitoring indoor alarm reports to the police immediately, also show abnormality immediately on the screen of computing machine simultaneously signal and leakage point position thereof, this moment, the maintainer can organize manpower to overhaul immediately.
After the present invention realizes; not only can find the position of escape of liquid early, exactly; prevent owing to the generation of leaking phenomenons such as produce on fire, blast, murder by poisoning, pollution; whether be damaged but also can detect pipeline outer protection layer simultaneously; and then the exterior materials that causes has promptly played the effect of early prevention directly to Corrosion of Pipeline, destruction.
Description of drawings: Fig. 1 is a detection system schematic diagram of the present invention.
Among the figure, the 1-pipeline outer wall, 2-outer wall protective seam, the 3-sensor, 4-afflux space, the 5-transmission cable, the 6-alarm, the 7-robot calculator, 8-monitors the chamber.
Embodiment: for detecting outer wall is in the petroleum pipeline of φ 325mm, and we can prepare several φ
In=325mm, φ
In=365mm, the annulus of thick 5mm is at a distance of L=6m, be fixed on the pipeline, with photoelectric sensor, be installed in desired location then, afterwards with polyurethane foam plastics as heat-insulation layer, wrap in (the afflux locus is reserved in attention) on the pipeline, be that anticorrosive coat wraps in outermost layer with the tygon duricrust at last, with communication cable one termination sensor, the other end links to each other with computer system, computing machine should select 386 type industrial control computers, and computing machine is connected with an alarm.
After being equipped with by above-mentioned way, can drop into to detect through debugging and use.
Claims (1)
- A kind of method that is used for test fluid transport pipeline or hold-up vessel leakage, it is characterized in that: make several afflux spaces (enclosure space) in the outside of liquid conveying pipe or hold-up vessel, in each afflux space, all to lay plurality of sensors, position according to each afflux space, sensor place, it is compiled into position encoded accordingly, is connected with electronic computer system with alarm by cable then.
