Pressure Air-foam proportion Mixing Device PHZY(M) Series Tank(diaphragm)
Executive Standard: GB20031-2005 "Foam Fire Extinguishing System And Parts General Technical Conditions"
The pressure air-foam proportion mixing device of PHZY (M) series tank (diaphragm) is constituted by foam tank, pressure proportional mixer, water inlet, wateroutlet, control valve and other parts. When the pressure water flows through the proportional mixer, water and foam could be mixed as per certain ratio automatically, and then the foam mixed liquid could be exported for producing air foam for foam generator and jetting device, which are used for putting outfire. This device is divided into vertical type and horizontal type. A capsule made from synthetic rubber is contained inside of the tank, and foam liquid is filled in the capsule and separated with water, which becomes the characteristic of diaphragm type. Not only it is applicable to general proteinand fluorine-protein foam liquid, it is particularly suitable for aqueous film-forming foam liquid. Meanwhile, surplus foam liquid could be continued to use after extinguishment. Featured by safety, reliability, high fire extinguishing efficiency and other advantages, this device could be applied to petrochemical enterprise, oil depot, oil-transportation wharf, airport and other significant engineering places.
