Description

Technical Field

[0001] The utility model relates to the technical field of gas alarm devices, in particular to a bottled gas leakage alarm device. Background Art

[0002] Once a bottled gas leaks, it will cause great risks. Natural gas is mainly composed of methane, which is a colorless, odorless, flammable gas. Natural gas leaks may be caused by pipeline ruptures, equipment failures, operational errors, etc. Natural gas is a flammable gas. When it leaks to a certain concentration, it may cause an explosion when encountering open flames, sparks or electric arcs. After natural gas leaks, it will occupy a certain space, resulting in a decrease in oxygen content, which may cause suffocation of people. Natural gas contains toxic components such as hydrogen sulfide. High concentrations of hydrogen sulfide are harmful to the human respiratory system, nervous system, etc. Natural gas is one of the greenhouse gases. Large-scale leakage will aggravate the greenhouse effect and have a negative impact on the environment. Natural gas needs to be used safely in actual use.

[0003] In actual use, bottled natural gas will be equipped with a valve device, but after long-term use, the pipeline connecting the natural gas may age or be damaged, which will cause natural gas leakage. Most of the existing devices have an alarm function. When the natural gas concentration reaches the preset value, an alarm will be issued to remind you, but the leakage of natural gas will continue, causing the concentration of natural gas to continue to increase, thereby damaging the environment and affecting the human body, and even causing greater impact. Therefore, it is urgent to solve this problem. Utility Model Content
