Description

Technical Field

[0001] The utility model relates to the technical field of valve groups, in particular to an assembled valve group for a gasoline filling machine. Background Art

[0002] Before the car bodies roll off the assembly line in the automobile factory's final assembly workshop, they need to be filled with gasoline. Gasoline is a Class A flammable liquid. After leakage, its vapor forms an explosive mixture with air, which can cause combustion and explosion when exposed to open flames or high heat, posing a high risk.

[0003] At present, there is no unified form for the installation of valve groups in front of gasoline filling machines in different factory areas. They are often installed close to the gasoline filling machines. This leads to the installation of valves at the end of gasoline pipelines, which occupy a large area and are not compact and beautiful; the cut-off valves are installed high or low, which are not easy to operate; the installation position of combustible gas detectors is not standardized, and the leakage alarm fails. This is not only not conducive to workshop management, but also buries hidden dangers for workshop safety management. Utility Model Content
