Foam bladder tanks is made from tank, bladder, pressure-type proportioner, safety valves, control valves, level gauge and a lot of ancillary components. Pressed water is divided into two parts according to a certain ratio(1: 99 or 3: 97 or 6: 94), 99%(97% or 94%) of the pressed water flow to the Proportioner, and 1%(3% or 6%) of the pressed water flow to the interlayer between tank and bladder, the water in interlayer will push foam concentrate in bladder into Proportioner. Foam concentrate will be injected into pressed water that flows through the proportioner and form foam solution, then the foam solution will flow to foam producing equipment, such as foam chamber and so on. Finally, air-foam concentrate is applied to put out fire.
The foam concentrate in the bladder can be used next time because it doesn't contact with water.
Type of Proportioner: 1%, 3%, 6%.
