The high expansion foam forming equipment is a key component of generating and spraying foam in the high expansion foam extinguishing system. It can mix the foam mixture with air in a short time to form a large amount of foam, which can quickly cover the fire area and isolate it from the air, so as to achieve the purpose of fire extinguishing. High multiple foam water consumption is very little, water damage loss is less, can effectively eliminate smoke and gas, suitable for full or partial flooding fire extinguishing in limited space. It is suitable for warehouse, garage, liquefied gas station, liquid collecting tank, chemical workshop, passenger and cargo ship, large coal yard, large garbage yard, etc.
