) Firefighting foam tank) is mainly composed of a foam liquid pressure storage tank with a capsule and a pressure-type proportional mixer made using the Venturi principle. When the water in the system pipe network passes through the proportional mixer pressure reducing orifice plate When, a pressure difference will form between the front and back of the orifice plate. A part of the water (% or %) at the high pressure point enters the tank through the water inlet pipe of the foam tank, squeezes the capsule, and squeezes the foam liquid in the capsule through the outlet pipe of the foam tank to the low pressure part of the proportional mixer to mix with water to form The foam mixture is output to the foam generating equipment (medium, low, and high expansion foam generators, foam guns, foam cannons, etc.) and mixed with air to produce foam for fire extinguishing. This device is widely used in oil depots, chemical plants, hangars, oil fields, fuel boilers, underground garages and other places.

) ) series fire foam tanks are composed of pressure tanks, capsules, proportional mixers, safety valves, exhaust valves, pressure gauges, one-way valves and various control valves and pipelines. The pump unit supplies pressure water, which replaces the foam in a certain proportion and mixes it with the pressure water to form a foam mixture. Since the capsule separates the foam liquid from water, the foam liquid is not used up once and can be used again next time with stable and reliable mixing accuracy.

) ) Working principle & When the pressure water flows through the proportional mixer, a part of the pressure water (%~%) enters the foam liquid storage tank from the branch pipe to squeeze the capsule and replace it The equal amount of foam liquid and another part of water (%~%) are mixed in the proportional mixer to form a foam mixture and provided to the foam generating device to generate air foam for fire extinguishing.
