Pressure Fire Tank

   Storage stage: In the non-working state, the foam liquid is stored in the capsule inside the tank, and the chamber outside the capsule is filled with a certain pressure of gas (such as compressed air or nitrogen). At this time, the foam is isolated from the outside world to maintain its stable performance.
Mixing stage: When a fire breaks out, the fire pump starts and sends the fire water through the inlet pipe to the foam tank. Under the action of pressure, water enters the outer chamber of the capsule and squeezes the capsule so that the foam liquid inside the capsule is squeezed out through the outlet pipe. The foam liquid and water are mixed in the proportional mixer according to the set ratio to form the foam mixture.
Fire extinguishing stage: the mixed foam mixture is transported to the fire extinguishing equipment such as fire sprinkler and fire cannon through the liquid outlet pipeline. These equipment spray or spray the foam mixture to the fire scene. The foam mixture forms a large amount of foam in the air and covers the surface of the combustion material, and achieves the purpose of fire extinguishing by isolating the air and cooling.
