Foam Bladder Tanks

Bladder foam tank is mainly composed of a foam pressure tank with capsule and a PHY pressure proportional mixer based on venturi principle. When the water flow in the system pipe network passes through the pressure reducing orifice plate of the proportional mixer, there will be a pressure difference between the front and back of the orifice plate. Part of the high pressure water (3% or 6%) through the foam tank inlet pipe into the tank, squeeze the capsule, the capsule of the foaming agent, through the foam tank pipe extrusion of produced liquid to proportioner low-pressure mixed with water to form foam mixture, the formation of foam mixture output to produce equipment (medium, low, high expansion foam generator, bubble gun, Foam monitor, etc.) and air mixture foam part of water through the pipe inlet valve "into the storage tank water cavity, squeeze the capsule, due to the small pressure difference before and after the nozzle, makes the foam liquid within the capsule by pipettes are mix with water become foam mixture flow, the air foam generator or other squirt foam injection equipment for fire fighting work. The storage tank is made of a rubber capsule, so that water and foam separated, each time after use, water and foam in the tank failed to mix and keep the performance of the original foam liquid unchanged, can continue to use, to avoid the waste of foam liquid.
