Description

Technical Field

[0001] The utility model relates to the technical field of natural gas leakage detection device installation, in particular to a natural gas pipeline leakage detection device installation rack. Background Art

[0002] Natural gas pipelines, as a means of transporting and storing natural gas needed in modern people's homes, have become an indispensable part of daily life. However, during use, improper use or corrosion may cause natural gas leakage, leading to fire accidents or poisoning. Natural gas leak detection alarm instruments are now installed on pipelines on the market to detect natural gas leaks on the pipelines. When the current natural gas pipeline leak detection alarm instruments are installed on the natural gas pipelines, their installation points are installed through the bottom threads. The installation position is exposed to the outside. If the thread groove is exposed to the outside for a long time, the thread groove will be filled with impurities and corroded, resulting in rust and other problems, which will affect the service life. It will also cause inconveniences during subsequent rotation, disassembly or installation, resulting in reduced overall work efficiency of the staff.

[0003] In response to the above problems, the inventors proposed a natural gas pipeline leakage detection device mounting bracket to solve the above problems. Utility Model Content
