2. Zhejiang high-speed water mist nozzle parameters

There are many parameters for high-speed water mist nozzles in Zhejiang. By providing reasonable technical parameters, different types of high-speed water mist nozzles can be designed and produced based on these parameters. The main parameters of Zhejiang high-speed water mist nozzles include working pressure, flow coefficient, thread size, material, atomization angle, droplet size, range, etc. The following are the meanings and conventional values ​​of different parameters of Zhejiang high-speed water mist nozzles:

1. Working pressure: Under normal circumstances, the greater the working pressure of the sprinkler head, the smaller the size of the water mist droplets, the better the atomization effect, and the higher the fire extinguishing and cooling efficiency.

①When used for fire extinguishing, it should not be less than 0.35Mpa

② When used for protective cooling, it should not be less than 0.2Mpa

③The working pressure of Class A, B, B and C liquid storage tanks should not be less than 0.15Mpa

2. Flow coefficient: The flow coefficient K of the nozzle is 16~102, which is determined by the nozzle manufacturer.

3. Atomization angle: generally available in five specifications: 45°, 60°, 90°, 120°, and 150°.

4. Thread size: The size of the high-speed water mist nozzle interface connection, commonly used thread connection methods, including internal threads and external threads, the size can be customized.

5. Effective range: refers to the distance between the highest point of the water mist and the nozzle when the nozzle sprays horizontally.

6. Droplet diameter: The average diameter of water droplets changes with the working pressure of the nozzle. The greater the pressure, the smaller the average diameter of water droplets.

Generally, the particle size of droplets from high-speed water mist nozzles should be in the range of 0.3~1mm.
