Low pressure carbon dioxide valve Industry Knowledge Extension

During the fire extinguishing process, how does the low pressure carbon dioxide valve replace the oxygen in the protected area?
During the fire extinguishing process, the low pressure carbon dioxide valve plays a vital role. It is responsible for accurately controlling the release of carbon dioxide to effectively replace oxygen in the protected area to achieve the purpose of extinguishing the fire. This process not only involves the principle of gas replacement in physics, but also needs to consider many aspects such as fire extinguishing efficiency, safety and environmental adaptability.
First, when a fire occurs, the fire detection system or manual operation will trigger the opening of the low pressure carbon dioxide valve. The valve responds quickly to precisely regulate the rate at which carbon dioxide is released from the storage vessel, based on the system's preset pressure and flow parameters. This process needs to ensure that carbon dioxide enters the protected area in a stable and controlled manner, both to achieve fire extinguishing effects and to avoid overpressure or other safety hazards.
As carbon dioxide enters the protected area, because it is denser than air, it quickly sinks and spreads throughout the space. During this process, carbon dioxide is replaced with the air and oxygen in the protected area. Since carbon dioxide does not support combustion, as its concentration increases, the oxygen content in the protected area gradually decreases, effectively inhibiting the spread of fire.
At the same time, the release of carbon dioxide also brings a cooling effect. Because carbon dioxide absorbs heat during release, this helps lower the temperature around the fire, further controlling the fire. This cooling effect combined with oxygen replacement constitutes the highly efficient fire extinguishing mechanism of the low pressure carbon dioxide fire extinguishing system. During the entire fire extinguishing process, precise control of the low pressure carbon dioxide valve is crucial. It needs to adjust the release amount and flow rate of carbon dioxide in real time according to the actual fire situation and the preset parameters of the system. This requires valves to be highly sensitive and reliable to ensure quick and accurate response in emergencies.
In addition, low pressure carbon dioxide valves also need to consider environmental adaptability. Since fire extinguishing systems may be deployed in various environments, such as high temperature, high humidity, corrosion and other harsh conditions, valves need to have good weather resistance and corrosion resistance to ensure their long-term stable operation.
To sum up, low pressure carbon dioxide valves play a key role in the fire extinguishing process. It achieves the purpose of extinguishing fire by precisely controlling the release of carbon dioxide and effectively replacing oxygen in the protected area. At the same time, valves also need to have a high degree of safety and reliability to adapt to various complex and harsh fire-fighting environments.
