Foam Proportioning Equipment for Fire Protection
Foam proportioning equipment is designed to provide foam solution for fire foam system. It is mainly consist of pressure tank, bladder, proportioner, control valves, pressure gauge and pipelines. High-pressure water is needed to swap out foam concentrate (stored in bladder in the tank) from the tank as a certain proportion. Foam concentrate then mix with pressurized water and form foam solution. For bladder is separated from the water that it can be utilized next time if not finished. Besides, there is feed inlet to refill or rechange foam concentrate.
Working Principle:
When pressurized water flow through the proportioner, a small part of water (3%~6%) flow into tank from water inlet and press bladder to swap out equal foam concentrate to mix with another part of water (97%~94%) in proportioner. Foam solution flows out from outlet and was supplied to foam generators or foam nozzles through pipelines.
Characteristic:
1. Customized capacity from 200~15000 liters
2. Big flow range.
3. Two types: horizontal and vertical.
