Aqueous film-forming foam fire hydrant box is a new type of high-efficiency low-expansion foam fixed fire extinguishing device. When the pressure water passes through the proportional mixer, the water and foam liquid can be mixed according to the specified proportion and the foam gun will generate foam to extinguish organic solid matter and soluble solid fires, especially for extinguishing wood, cotton and oil fires. It is particularly effective .
The foam fire hydrant box is mainly composed of a box body, a foam liquid storage tank, a proportional mixer, a foam gun, a hose reel (fire hose), a foam liquid supply valve, a pipe and an alarm.
The series of bolt boxes are made of high-quality steel plates. Both the inner and outer surfaces are coated with epoxy polyester powder electrostatic spray coating. It has good adhesion, is bright, smooth, beautiful and elegant, and will not fall off under collision. The foam liquid storage tank is made of stainless steel and is corrosion-resistant.
When a foam fire hydrant box is used to extinguish a fire, when water with a pressure of no less than . A vacuum (negative pressure) is formed in the room, so the foam liquid in the foam liquid storage tank enters the mixer through the suction pipe under the pressure of the atmosphere and is mixed with pressure water to finally reach a certain proportion of mixed liquid. When the mixture with a certain pressure flows to the spray gun, the foam mixture is foamed. Thus achieving the effect of foam fire extinguishing.
