3C smoke fire prevention valve, also known as smoke exhaust fire prevention valve, is mainly used in the pipelines of ventilation and air -conditioning systems, especially above the ceiling.This valve plays a key role in the smoke discharge system, usually installed on the smoke discharge system.
Under normal circumstances, 3C smoke fire prevention valves are in a state of opening, allowing air flow.However, when the fire occurs, if the temperature of the smoke in the smoke exhaust pipe reaches 280 degrees, the valve will be automatically closed, thereby preventing the fire from spread through the smoke discharge system.This shutdown action can meet the requirements of smoking amount and refractory integrity within a certain period of time, and play a role in smoking fire -blocking fire.
In addition, 3C smoke fire prevention valves also have the function of electric off.Through the DC24V power supply, the valve can be remotely shut down.This function is particularly important at the import of fire exhaust fan. When a fire accident occurs, the anti -control room can control the valve to open, and the fire smoke exhaust fan can also be turned off when it is closed.
In addition to the above functions, the 3C smoke fire prevention valve also has other advantages, such as low air leakage, good air tight performance, small electric opening consumption current, strong anti -corrosion performance, long service life (material is stainless steel)EssenceThese advantages make 3C smoke fire prevention valves have a wide range of application prospects in the fluid control system.
In general, 3C smoke fire prevention valves play an important role in ventilation and air -conditioning systems, especially when the fire occurs, it can effectively prevent the spread of fire and protect peoples life and property safety.
The above is the application of 3C smoke fire prevention valve
