The pressure-type foam proportioning mixing device is mainly composed of a foam liquid pressure storage tank with a capsule and a pressure-type proportioning mixer made using the Venturi principle. When the water flow in the system pipe network When the orifice plate is decompressed through the proportional mixer, a pressure difference will be formed before and after the orifice plate. A part of the water (3 or) at the high pressure enters the tank through the 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 foam. The mixed liquid, and the formed foam mixed liquid is output to the foam generating equipment (medium, low, and high multiple foam generators, foam guns, foam cannons, etc.) and mixed with air to produce foam fire extinguishing. This device is widely used in oil depots, chemical plants, hangars, oil fields, fuel boilers, underground garages and other places.
