) The pressure-type foam proportioning mixing device mainly consists of a foam liquid pressure storage tank with a capsule and a It is composed of a pressure-type proportional mixer made using the Venturi principle. When the water in the system pipe network flows through the pressure-reducing orifice plate of the proportional mixer, a pressure difference will be formed before and after 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 pressure proportional mixing devices consist of pressure tanks, capsules, proportional mixers, safety valves, exhaust valves, pressure gauges, one-way valves and various control valves and pipelines. Pressure water is supplied from the pump unit, and the foam is replaced according to a certain ratio and then mixed 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, displacing an equal amount of foam liquid Mix it with another part of water (%~%) in a proportional mixer to form a foam mixture and supply it to the foam generating device to generate air foam for fire extinguishing.
