PHYM Pressure Type Proportional Mixing Device Parameters
Overview
PHYM series pressure proportional mixing device is an important equipment of fixed foam extinguishing system engineering.Foam mixture can be provided in combination with foam generator, foam nozzle, foam gun, foam cannon or other injection equipment to produce low-expansion air foam to fight class A or water-soluble and insoluble class B fires.
Product standard: GB 20031-2005 general technical conditions for foam extinguishing systems and components.
Application scope
The device can be used in oil field, oil refinery, petrochemical plant, garage, aircraft hangar, oil depot transport ship and dock and other places.
Composition of
It is mainly composed of foam storage tank with capsule and foam proportioner, water inlet pipe, liquid outlet pipe, exhaust pipe, position mark and liquid discharge pipe.
Working principle
When the system works, the pressure water fills the tank with water from the inlet valve through the water inlet pipe, squeezes the capsule to replace the foam liquid, and mixes with water in proportion in the proportioner to form the foam mixture liquid, which is transported out by the outlet.
