Working Principle
The balanced foam proportioning device mixes water and foam concentrate in a preset ratio through water inlet pipes and foam concentrate pipes. When water flows through the equipment, negative pressure is created to suck in the foam concentrate, which fully mixes with water. The mixture is then delivered to foam nozzles via mixing pipes for foam spraying. The device's balanced design ensures consistent proportioning, thereby guaranteeing stable fire-extinguishing efficiency.
Main Working Components
Mixing Chamber: Facilitates the uniform mixing of water and foam concentrate with a rational design to ensure thorough blending.
Water Inlet Valve: Controls water inflow and connects to the system's water source.
Foam Concentrate Valve: Regulates the inflow of foam concentrate to ensure proportional supply.
Pressure Sensor: Monitors system pressure to maintain operation within a safe range.
Storage Tank: Stores foam concentrate to ensure long-term and stable supply.
Application Scope
Petrochemical Industry: Fire suppression in large chemical facilities and oil refineries.
Logistics Warehouses: Particularly warehouses storing flammable and explosive materials.
Crude Oil Terminals: Loading and unloading areas for crude oil and other dangerous goods.
Airports: Fire protection for large aircraft and airport facilities.
Offshore Platforms: Safety protection for offshore oil and gas extraction facilities.
Power Substations: Protection of power equipment plants against fire hazards.
