As a safety protection device in the gas transmission and distribution system, the gas emergency cut-off valve is a semi-automatic safety cut-off valve. That is, once the valve is closed, it will no longer change with the power on (or power off) state, and it will still remain in its closed position. The valve can only be returned to the open state through manual operation.
The main function of the gas safety shut-off valve is to receive the electrical signals sent by the gas alarm control system or other alarm systems (multiple detection methods can be combined), and make the valve stem components act through the magnetic force of the solenoid coil, so as to open or close the valve and achieve the purpose of controlling the flow of media in the pipeline.
The gas alarm shut-off valve is a valve installed on the urban gas pipeline (gas inlet pipe, main pipe or main pipe), which can improve the safety control capability of the pipeline behind the valve and the gas station, and ensure the safety of gas transmission, distribution and use in the gas area.
Gas quick shut-off valve is widely used in gas, petroleum, chemical industry, gas boiler and other industries, and is an essential key equipment for industrial gas process control system.
