Introduction

The foam sprinkler is a special fire extinguishing parts mainly used in low-expansion foam spray system which can produce and jet air bubble. Foam proportionate system supply foam solution for these nozzles. When foam solution was conveyed to nozzles by pipelines, the nozzle inhales air at outlet to make foams and put out fire.

Working Principle

When pressurized foam solution flows through the cavity of the nozzle, its pressure will be reduced because of throttling. That will result in vacuum and inhale air. The foam solution then become foams after dispersed by nozzle.
