what is the foam tank Working principle

As shown in Figure 1, the diaphragm-type storage tank is equipped with a high-strength rubber membrane, which completely separates the foam liquid from the water in the tank, so that the remaining foam liquid can still be used after use, completely avoiding the foam liquid Waste. When the pressure water flows through the mixer pipeline, part of the water enters the storage tank through the water inlet pipe, and most of the water enters the nozzle of the proportional mixer along the mixing pipeline and sprays out to the diffuser. When entering the nozzle, the caliber decreases and the flow velocity increases. Due to the lateral turbulent diffusion of the jet particles, a low-pressure mixing chamber is formed between the nozzle outlet and the diffuser. The water entering the tank presses out the foam liquid stored in the capsule from the outlet pipe, enters the low-pressure mixing chamber of the proportional mixer through the orifice, and merges with the large pressure water flowing through the nozzle of the proportional mixer to form 3% or 6% The foam mixture is transported to the foam generating equipment to generate air foam for fighting Class A, B, C liquid fires and solid fires such as wood, paper, textiles, etc.
