Description

Technical Field

[0001] The utility model relates to the technical field of air leakage detection devices, in particular to an air leakage detection device. Background Art

[0002] A natural gas pipeline refers to a pipeline that transports natural gas from a mining site or processing plant to a city gas distribution center or industrial enterprise user. Using a long-distance natural gas pipeline to transport natural gas is a way to transport a large amount of natural gas on land. During the use of long-distance natural gas pipelines, a gas leakage detection device is required. Most of the gas leakage detection devices in the prior art detect pipelines, but there is no corresponding detection at the joint of the natural gas pipeline. Because most natural gas pipeline joints are welded, there are imperfect welding points during welding, or after long-term use, gas leakage is likely to occur, which is inconvenient to use. Therefore, we propose a gas leakage detection device. Utility Model Content

Because most of the natural gas pipeline joints are connected by welding technology, there are problems such as imperfect welding points during welding, or gas leakage is prone to occur after long-term use.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] Preferably, a sliding rod is slidably connected inside the fixed frame, the adjusting block is fixedly connected to the sliding rod, a first spring is sleeved on the outside of the sliding rod and located on one side of the adjusting block, and the end of the sliding rod away from the adjusting block is fixedly connected to the connecting block.

[0016] It can be understood that the utility model achieves a sealing effect through the provision of the sealing gasket.

[0017] Preferably, a flow guide pipe is fixedly connected to one side of the connection frame.

[0018] It is understandable that the utility model can achieve a pressure relief effect when the pressure is relatively high through the provision of the flow guide pipe.
