Embodiment
As depicted in figs. 1 and 2, the present invention program 1 heat supply pipeline leak testing and monitoring system comprises heat supply steel pipe 1, pipeline compensator 2, Check point 3, detector 6, cable 8 and output line 9, connect by pipeline compensator 2 between the heat supply steel pipe 1, the thermal insulation layer of heat supply steel pipe 1 and pipeline compensator 2 inside is provided with detection line 10, detection line 10 is the plain conductor of circle or flat, Check point 3 places are provided with the Check point terminal board of signal converting to detector 6, be electrically connected by cable 8 between Check point 3 and the detection line 10, be connected by signal transmssion line 9 between detector 6 and the Check point 3.Detector 6 is used for receiving and showing Check point 3 output signals, and signal transmssion line 9 is used to transmit Check point 3 signals, and Check point 3 and cable 8 are embedded in ground 7 times.Successively each Check point 3 signal is detected the Pipeline Leakage Point scope by detector 6.
The present invention program 2 as shown in Figure 3, be in scheme 1 described heat supply pipeline leak testing and monitoring system, to add the bus 4 that is used to monitor the computer system 5 of pipeline working state and is used for all Check point output signals are sent to simultaneously computer system 5, Check point 3 places can also be connected to bus 4 with signal converting to the output line 9 of detector 6 in the scheme 1, transfer signals to computer system 5 by bus 4, bus 4 is connected with computer system 5, signal transmssion line 9 is embedded in ground 7 times like this, by computer system 5 staff can be real-time the variation of monitoring Check point 3 signals, distance between the Check point 3 can be set according to actual conditions, the detection line 10 of pipeline compensator 2 leads to Check point 3 separately, and the detection line 10 of heat supply steel pipe 1 can be taked single drawing or mode that many polyphones are drawn (below 3 36 meters).
When pipeline takes place to leak, the staff just can in time pinpoint the problems, and can determine the Position Approximate of leak source, because the reflection of Check point 3 output signals is the working state of certain duct length scope (as 20 meters), so after definite leak source scope, can dwindle the faut detection scope by other modes.
The heat supply pipeline leak testing and monitoring system working principle is: under the normal condition, be embedded between the detection line 10 of heat supply steel pipe 1 and pipeline compensator 2 thermal insulation layer inside and the insulation resistance between detection line 10 and the heat supply steel pipe 1 very big, when pipe leakage, just having ponding in the thermal insulation layer occurs, humidity can produce unusually, thereby between the detection line 10 and the insulation resistance between detection line 10 and the heat supply steel pipe 1 can diminish rapidly, about extract the resistance variations signal, by detection line 10 this signal is sent to Check point 3, by analysis, just can detect the residing scope of Pipeline Leakage Point to resistance variations.
