Horizontal Bladder Tank Foam Proportioning System

The bladder tank is mainly composed of a foam hydraulic pressure storage tank with capsules and a PHY-type pressure-type proportional mixer made of Venturi principle. When the water in the system pipe network flows through the pressure-reducing orifice of the proportional mixer, There is a pressure differential across the orifice. A part of the water (3% or 6%) at the high pressure 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 and water Mix to form a foam mixture, and the formed foam mixture is output to foam generating equipment (medium, low, high expansion foam generators, foam guns, foam cannons, etc.) and mixed with air to generate foam for fire extinguishing.
