Brass Foam Sprinkler Head
The foam sprinkler is a fire extinguishing device that generates and sprays air foam. The foam mixture is transported to the foam nozzle through the pipeline, and air is sucked at the outlet of the foam nozzle to form air foam, which is sprayed in the protected danger zone to achieve the purpose of fire extinguishing. in low-expansion foam spray systems.
Working Principle:
When the foam mixture with a certain pressure flows through the inner cavity of the foam nozzle, due to throttling, the flow rate increases and the pressure decreases, forming a negative pressure, inhaling air, and forming a certain multiple of air through the blowing effect in the nozzle.
