Problems solved by technology
[0002] Natural gas fuel is one of the earliest and widely used alternative fuels, but when the content of natural gas in the air reaches a certain level, it will suffocate people, and when the concentration of natural gas reaches a certain proportion, a huge explosion will occur, which will pose a threat to personal safety. influences
[0003] After the natural gas pipeline is installed, it is necessary to carry out natural gas leakage detection on the pipeline. When the general natural gas pipeline leakage detection and alarm device detects the leakage of the natural gas pipeline, it usually turns the device around the connection of the pipeline for detection. When the leakage is very small, the detection device may not be able to detect the leakage due to the influence of the air. In addition, the user needs to hold the detection device for a long time for detection, which may inhale too much natural gas, which will affect personal health

The invention discloses a leakage detecting and alarming device for a natural gas pipeline. The device comprises a monitoring box, wherein a clamping box is arranged at the right side of the monitoring box; empty cavities in which pipelines are arranged are formed in the right side surface of the clamping box and the left side surface of the monitoring box; in case of slow leaking of the natural gas in the pipelines, natural gas enters a storing chamber through a connection chamber, an expansion film expands after a time, and thus the leakage of natural gas in the pipelines can be detected; asealing mechanism and a clamping mechanism are matched, so that the leaked natural gas can be prevented from flowing from the device in natural gas pipeline leakage detecting process, and as a result,the health of a user in the leakage detecting process can be ensured, and the device detecting accuracy can be ensured; in addition, in case of little leaking of the pipelines, whether the expansionfilm in the detecting mechanism expands can be observed in order to determine whether the natural gas pipeline is subjected to leakage, and thus the problem that little leakage of the natural gas pipeline cannot be detected can be avoided.

technical field [0001] The invention relates to the technical field of natural gas leakage detection, in particular to a natural gas pipeline leakage detection and alarm device. Background technique [0002] Natural gas fuel is one of the earliest and widely used alternative fuels, but when the content of natural gas in the air reaches a certain level, it will suffocate people, and when the concentration of natural gas reaches a certain proportion, a huge explosion will occur, which will pose a threat to personal safety. influences. [0003] After the natural gas pipeline is installed, it is necessary to carry out natural gas leakage detection on the pipeline. When the general natural gas pipeline leakage detection and alarm device detects the leakage of the natural gas pipeline, it usually turns the device around the connection of the pipeline for detection. When the leakage is very small, the detection device may not be able to detect the leakage due to the influence of t...
