Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of natural gas line corrosion leakage detection device, comprise transmitter and receiver, described receiving machine comprises handle 1, magnetometer probe 2, alarm 3 and display device 4, be provided with processor 5, suction pump 6 and gas transducer 7 in described magnetometer probe 2, described processor 5 is electrically connected with gas transducer 7, alarm 3, display device 4 respectively.Wherein, described magnetometer probe 2 and display device 4 lay respectively at handle 1 two ends, and upwards, magnetometer probe 2 is downward for display device 4.Display device 4 is flexibly connected with handle 1 top, can all around rotate; Magnet base 8 is also provided with in the below of magnetometer probe 2.Described gas transducer 7 is positioned at the air outlet place of suction pump 6, and gas transducer 7 adopts catalytic combustion type sensor.Described alarm 3 is made up of buzzer and light emitting diode, and described light emitting diode is positioned at display device 4.
Fig. 2 is the display floater schematic diagram of display device 4.The left one side of something of display floater is Corrosion monitoring display floater, can know the trend of pipeline and sense of current and size, in the region of electric current generation bust, likely corrosion condition occurs according to the arrow on panel.The concentration of the natural-gas can observed in right panel is leaked in generation, and whether alarm sends sound, and whether tutorial light lights.
Fig. 3 is the catalysis element test circuit figure of gas transducer 3.The gas transducer 3 used is catalytic combustion type sensor, the Detecting element of catalysis element is formed spherical at the upper bag of platinum filament coil (φ 0.025 ~ φ 0.05) with aluminium oxide and tackiness agent, form through sintering, its outer surface is covered with the catalytic layer of the rare metal such as platinum, palladium.Adopt resistance bridge measuring circuit, in electric bridge, black element is Detecting element, and white element is compensating element, and white element only lacks catalyst layer compared with black element, and namely spoken parts in an opera element runs into natural-gas and can not burn.Voltage v is added at detection original paper two ends
0, make Detecting element keep high temperature (300 ~ 400 DEG C), when there being certain density natural-gas in air, due to burning, resistance value rises Detecting element, and electric bridge disequilibrium, exports v by voltage
i, play detection effect.
Fig. 4 is the principle schematic of the utility model examinations.Whether this device is reported to the police by the attenuation of pipe current signal and leakage alarm, judges whether the destructiveness of anticorrosive coat and buried pipeline leak.First transmitter is connected with pipeline, by high-power transmitter, the signal code (in low-down frequency (4Hz) pipeline current attenuation near linear) of approximate DC is sent to pipeline, then receive function and detect this distinctive signal transmitted through pipeline exactly, follow the tracks of and gather this signal, input processor, just can survey and draw out electric current [strength everywhere on pipeline.By analyzing curent change, realize the assessment to pipeline anticorrosion coating quality.Electric current [strength decays along with the increase of pipeline distance, when caliber, tubing, edatope are constant, pipeline anticorrosion coating insulating property are deteriorated, and the current attenuation be applied on pipeline is more serious, realize assessing anticorrosive coat damaged condition by the decay analyzing electric current.
When detecting ground natural gas line, only need transmitter to be connected with pipeline, then hand-held device moves along pipeline, just the corrosion of detectable pipeline and leakage situation.When the air containing inflammable gas, when delivering to gas transducer by suction pump, the resistance of Detecting element can become rapidly large (size of its change in resistance follows the concentration of gas to be directly proportional), exports a voltage signal simultaneously, after circuit amplifies, deliver to display section, and produce alarm signal.When needs detect buried ground pipeline, can detect mouths or well head detect by some setting in advance, if detect mouth or well head has rock gas to release, by suction pump, gas is delivered to gas transducer, device is handled it and is sent alarm signal subsequently.While carrying out Leak testtion, Corrosion monitoring also can carry out, and both can not clash; Also carry out separately to arrange two kinds of detections simultaneously.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art and is realized.
