Storage tank pressure proportioner
This equipment is for the foam liquid storage and mixing foam liquid with pressure water. Because rubber bladder separates water from foam liquid, the foam liquid wont be used up and can be saved for next use. The mixing precision is stable and reliable.
This equipment can be used in wide flow and pressure range with small pressure loss, being applied in high, medium and low expansion fire-extinguishing system broadly.
When passing proportioner, some water (3%-6%) enters foam storage tank and rubber bladder to exchange the same amount foam liquid, which will be mixed with another amount water (97%-94%) in proportioner and then flow by the air foam generator and put out the fire together with air.
