“1. The nozzle of dry powder fire extinguisher usually adopts the zoom nozzle hole design, ‌ this design is helpful to optimize the spraying effect of fire extinguishing agent, ‌ improve the fire extinguishing efficiency. ‌ The nozzle material of dry powder fire extinguisher should have good pressure resistance ‌ to ensure that it can still work normally under high pressure environment. ‌
2. The nozzle of carbon dioxide fire extinguisher may adopt the design of green base, ‌ this design is conducive to better distribution of fire extinguishing agent, ‌ at the same time protect the nozzle and base, ‌ to ensure the fire extinguishing effect. ‌
3. The nozzle of a light water fire extinguisher may involve wind pressure, ‌ spray amount and other parameters, ‌ the choice of these parameters depends on the specific use environment and fire extinguishing needs. ‌”
