Embodiment Construction
[0030] Embodiments of the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and therefore are only examples, rather than limiting the protection scope of the present invention.
[0031] like Figure 1-2 As shown, the present invention provides an underground gas pipeline leak detection system, which includes a leaking gas conveying part 1 , a detector 2 , a signal transmission device 3 and a monitoring center 4 . Among them, the leaked gas delivery part 1 is used to receive the gas leaked from the gas pipeline 7, and transport the gas leaked from the gas pipeline 7 to the valve well of the underground gas pipeline 7; the detector 2 is set in the valve well to detect the gas pipe leakage The gas leaked from the valve in the valve well and the gas leaked from the valve in the valve well; the...

The invention discloses a system for detecting leakage of an underground gas pipeline. The system comprises a leaking gas delivering part which is used for receiving gas leaked from a gas pipeline and delivering the gas leaked from the gas pipeline into a valve well of an underground gas pipeline, a detector which is arranged in the valve well and is used for detecting gas leaked from the gas pipeline and gas leaked from the valve in the valve well, a signal transmission device which is in communicating connection with the detector and is used for receiving a signal from the detector and transmitting the signal to the outside, a monitor center which is used for receiving the signal from a signal transmission device and analyzing the received signal so as to monitor operation of the gas pipeline. The system can be used for effectively finding out the leaking situation of a gas underground pipeline in time and correctly and quickly focusing the gas leaking well section, even a specific leaking position, so that time is reserved for emergency treatment of operators, and occurrence of safety accidents can be prevented. The invention further provides a method for detecting leakage of an underground gas pipeline.
Description
technical field [0001] The invention relates to the technical field of leakage detection equipment for underground gas pipeline networks, in particular to an underground gas pipeline leak detection system and an underground gas pipeline leak detection method. Background technique [0002] The underground pipelines in the city are criss-crossed, providing various energy sources for residents and enterprises, known as the "lifeline" of the city. [0003] The gas pipeline in the underground pipeline network provides residents with a natural and clean fuel, and the gas pipeline may cause gas leakage due to the aging of the pipeline and the corrosion of the pipeline connection, especially in the valve well. The underground valve well is a closed In the limited space of the gas valve well, the pipelines, valves and other facilities in the gas valve well are easy to accumulate gas after long-term operation in an unventilated and humid environment. When the gas accumulates to a cer...
