Description

Technical Field

[0001] The utility model belongs to the technical field of emergency cut-off valves, and more specifically, relates to an electromagnetic gas emergency cut-off valve with a quick coupling. Background Art

[0002] A gas emergency cut-off valve is a safety device mainly used in gas pipeline systems. Its basic function is to quickly cut off the gas supply when detecting gas leakage or other emergency situations to ensure the safety of personnel and facilities. It is widely used in domestic, industrial, and commercial gas systems, as well as in linkage with safety protection systems such as gas leakage alarm systems and fire alarm systems.

[0003] An electromagnetic emergency cut-off valve is a type of gas emergency cut-off valve that uses electromagnetic force to drive the opening and closing of the valve. This type of cut-off valve usually includes an electromagnetic coil. When the coil is energized, it generates a magnetic force that attracts the moving iron core inside the valve, thereby driving the opening or closing of the valve. Electromagnetic cut-off valves are widely used due to their fast response speed and convenient remote control.

[0004] However, some inconveniences may be encountered during the installation of electromagnetic emergency cut-off valves. For example, when connecting to the original pipeline, it is necessary to spiral wind the pipeline into the cut-off valve, which is inconvenient for installation. The limited space is not conducive to the large rotation installation of the valve body, resulting in limited rotation position of the valve body. Summary of the Utility Model
