1．燃气总管道系统除了设计有电动快切阀外，还设计了机械自动切断阀门，当

1. In addition to the electric quick cut valve, the gas main pipeline system is also designed to automatically shut off the valve. When the system is overpressured or the regulator valve is damaged, it can quickly cut off the total gas to ensure the safety of the system. <br>2. An air-fuel proportional valve is installed in front of each burner to ensure that the gas valve can be opened before the nozzle under certain air pressure, ensuring the safety of system ignition. <br>3. An automatic purge function was added to the ignition procedure to ensure safe ignition.

1. In addition to the design of the gas general pipeline system has an electric fast-cut valve, but also designed a mechanical automatic cut-off valve, when the system overpressure or regulator valve damage can quickly cut off the total gas, to ensure the safety of the system.<br>2. A free-burning proportional valve is installed before each burner, ensuring that the gas valve must be opened before the mouth under air pressure, ensuring the safety of the system ignition.<br>3. The automatic blow-off function has been added to the ignition procedure to ensure safe ignition.

1. In addition to the electric quick cut valve, the mechanical automatic cut-off valve is also designed for the gas main pipeline system. When the system is overpressured or the pressure stabilizing valve is damaged, the total gas can be cut off quickly to ensure the safety of the system.<br>2. An air-fuel proportional valve is installed in front of each burner to ensure that the gas valve in front of the nozzle can be opened only when there is a certain air pressure, so as to ensure the safety of system ignition.<br>3. Automatic purging function is added to the ignition procedure to ensure safe ignition.
