Perfluorohexanone fire extinguishing nozzle model parameters

Perfluorohexanone (also known as FK-5-1-12) is an environmentally friendly and efficient fire extinguishing agent with excellent fire extinguishing properties and chemical stability, so it is widely used in fire extinguishing systems. As the core component of the perfluorohexanone fire extinguishing system, the parameter design and performance of perfluorohexanone fire extinguishing nozzles are crucial to effective fire prevention and control. The models of different parameter combinations are also different.

1. Perfluorohexanone fire extinguishing nozzle model

Perfluorohexanone fire extinguishing nozzles use different nozzles in different scenarios, so the models are also different. The following are the conventional models of nozzles for cabinet-type perfluorohexanone fire extinguishing devices. The materials used include stainless steel 304, brass and aluminum alloy, etc.:

1.QPT120/4.2, the flow coefficient is 120, the working pressure is 4.2MPa, and the interface thread is Rp1 1/4;

2.QPT140/4.2, the flow coefficient is 140, the working pressure is 4.2MPa, and the interface thread is Rp1 1/4;

3.QPT160/4.2, the flow coefficient is 160, the working pressure is 4.2MPa, and the interface thread is Rp1 1/2;

4.QPT180/4.2, the flow coefficient is 180, the working pressure is 4.2MPa, and the interface thread is Rp1 1/2;

5.QPT200/4.2, the flow coefficient is 200, the working pressure is 4.2MPa, and the interface thread is Rp2;

6.QPT220/4.2, the flow coefficient is 220, the working pressure is 4.2MPa, and the interface thread is Rp2;

7.QPT240/4.2, the flow coefficient is 240, the working pressure is 4.2MPa, and the interface thread is Rp2.

2. Perfluorohexanone fire extinguishing nozzle parameters

1. Nozzle type:

Perfluorohexanone fire extinguishing nozzles are usually divided into two types: spray type and gas liquefaction type. Spray nozzles are mainly used for direct fire extinguishing, by spraying perfluorohexanone into tiny droplets at the fire scene, and extinguishing the flames through cooling and chemical suppression. Gas liquefaction nozzles are used in the gas-driven part of the fire extinguishing system to liquefy perfluorohexanone gas and then spray it.

2. Injection mode:

Perfluorohexanone fire extinguishing nozzles can be designed into different spray modes, including spray, atomization and jet modes. Spray mode is suitable for local fire extinguishing, atomizing liquid perfluorohexanone into fine droplets to cover a larger area. Jet mode is suitable for remote fire extinguishing, spraying perfluorohexanone onto the fire source in a high-speed jet.

3. Injection angle:

The spray angle of the nozzle directly affects the spray range and effectiveness of liquid perfluorohexanone. Depending on the fire scenario, the nozzle can be designed with different spray angles, such as 30 degrees, 45 degrees or 90 degrees, etc., to confirm that the liquid can cover the fire source and quickly extinguish the flames.

4. Pressure parameters:

The working pressure of the perfluorohexanone fire extinguishing nozzle is the key factor to confirm its normal spraying. If the pressure is too high, the droplets may be too small, which is not conducive to the fire extinguishing effect; if the pressure is too low, the spray distance and coverage area may be affected. Therefore, the design of the sprinkler head needs to consider the size and location of the fire source to determine the appropriate operating pressure range.

5.Jet distance:

The spray distance of the nozzle directly affects the projection range of perfluorohexanone liquid. When designing, it is necessary to comprehensively consider factors such as the height of the fire source and the layout of the environment to confirm that the spray distance of the nozzle can cover the fire source area to achieve effective fire extinguishing effects.

6. Injection duration:

The spray duration of the nozzle depends on the storage capacity and design requirements of the system. After a fire occurs, the sprinkler head needs to continue spraying for a long enough time to confirm that enough perfluorohexanone liquid is sprayed into the fire source area to effectively carry out fire extinguishing operations.

7. Automation and control:

Modern perfluorohexanone fire extinguishing nozzles are usually combined with fire detection systems, alarm devices and automatic control systems to automatically detect fires and trigger nozzle injection. Through accurate sensors and control algorithms, sprinklers can respond quickly when a fire occurs, maximizing fire extinguishing efficiency.

In summary, the design and optimization of perfluorohexanone fire extinguishing nozzle parameters are crucial to the performance of perfluorohexanone fire extinguishing systems. Reasonable sprinkler nozzle design can ensure that fires are extinguished quickly and efficiently when a fire occurs, thus minimizing the losses caused by fires. With the continuous advancement of science and technology, the design and performance of perfluorohexanone fire extinguishing nozzles will continue to be improved, making greater contributions to fire prevention and control.
