The pressure foam proportioning device is the most common foam extinguishing equipment at present. The pressure type foam proportioning device is easy to install, use and maintain. The built-in capsule has excellent corrosion resistance. The cost is relatively affordable, and the equipment performance is stable and reliable. It is especially suitable for medium and small flow foam fire extinguishing systems. Mainly suitable for the production, storage, transportation, and use of flammable or combustible liquids; Places with fire hazards such as petrochemical enterprises, oil depots, loading and unloading docks, ship terminals, oil extraction platforms, aircraft hangars, and car garages. The pressure type foam proportioning device can be divided into horizontal, vertical, single proportioning mixer, double proportioning mixer, etc. according to the structure type, and users can choose according to the actual configuration needs and the location of the installation space. PHYM (L) series pressure type proportioning device is composed of foam liquid storage tank, pressure type proportioner, safety valve, control valve and some auxiliary parts. When the fire pressure water flows through the equipment, the proportional mixer divides its proportion, and a small part of the water flows into the interlayer of the foam liquid storage tank. The replaced foam liquid is mixed with the fire water of the other main pipes to form a certain proportion of foam liquid mixture, which is delivered to the foam generating equipment. PHYM series pressure type proportional mixing device is applicable to all kinds of foam liquid with mixing ratio of 3% and 6%.
