Foam Bladder Tank

What is Foam bladder tank?

The bladder type water tank is a part of the bladder type water tank proportional system, which requires no external power supply except adequate water supply. The bladder tank with suitable proportioners will inject foam concentrate into the water supply system of the firefighting system, and will automatically proportion under a wide range of flow and pressure. It mixes the template concentrate with water under a wide range of flow rates and pressures. After operation, the pressure drop is very low, and the water flows to the template concentrate.

The pressure of foam concentrate discharged from the bladder tank. Actually it is approximately the same as the pressure of water supplied at the water inlet connection of the tank. Since the airbag box is pressurized, the airbag should not be refilled during operation.

How dose foam bladder tank work?

Closed type foam water sprinkler device which is mainly composed of a closed sprinkler, a foam proportional mixer. Additionally, a wet alarm valve and a foam liquid control valve are also the components to the foam bladdder tank. Also pressure relief valve and pipe fittings as its one of the components, It can function for activating the linked pressure relief valve. Certainly, it also activate the foam liquid control valve allowing the pressurized water to mix with the foam liquid.

Application in wide ragne industries

When the alarm check valve starts, then the sprinkler ejects water to extinguish the fire hazards. Foam bladder tanks are widely used in underground parking, aircraft maintenance. Referring to car pool, oil pump room, petrochemical technology, etc, it is also important.
