Product Description

Cheap Price Sprinkler Fire Foam Spray Nozzle

Introduction
These Foam Spray Nozzles are typically used in fixed foam deluge systems and applied with the correct foam
concentrate type for the extinguishment of hydrocarbon fuel, polar solvents and other flammable liquid fires. Typical field
applications include aircraft hangers, chemical plants, pump rooms, tanker loading gantries, flammable liquid stores and
spray paint booths. The foam solution discharge rate is calculated by the area of the hazard multiplied by the application
rate. The nozzle flow is governed by the K-factor of the nozzle multiplied by the square root of the inlet pressure.
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.
