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%. The pressure type foam proportioning device is used to store foam extinguishing agent and replace foam extinguishing agent through the pressure type foam proportioner using the water supply of the pump set, and mix with the water supply in a certain proportion to form foam mixture. The horizontal foam tank (PHYM pressure type proportional mixing device) produced by Shandong Dongyue Crane Fire Fighting Equipment Manufacturing Co., Ltd. has a capacity ranging from 1000L to 10000L, and there are also differences in flow. Customers can purchase it according to their own needs.
