China Foam Bladder Tank Foam Tank Fire Fighting Foam Tank

Horizontal fire foam bladder tank for fire fighting
Introduction
Foam bladder tank, together with ratio controllers, form a balanced pressure proportioning system used to mix water and fire fighting foam together to generate an effective extinguishinTelecommunication & Broadcasting g medium.The bladder tank technology is a mixing method allows the water/foam ratio to remain stable by automatically adjusting to the variable flow rates and pressure conditions that may occur during system operation.This feature makes bladder tanks particularly suitable for multiOther Safety Products ple hazard systems, sprinkBearing ler systems and any other system operating under variaSorting Machine ble, non predictable, flow and pressure conditions.
Function
The bladder tank is a carbon steel pressure vessel contaSealing & Gaskets ining an elastomeric separation bladder between the water and foam concentrate. The bladder permits water pressure to be transferred to the foam concentrate without the two fluids mixing together. A ratio controller generates a water pressure drop by means of a reduced cross section where the water stream passes through it. As the foam concentrate pressure is higher than the pressure at the ratio controller, the foam starts flowing towards the water and mixing at a calibrated rate, which is dependant on the water flow rate.
