Pressure type foam proportion mixing device
Product overview
The source of the brand PHYM series pressure foam proportioning device is composed of pressure tank, capsule, proportional mixer, safety valve, pressure gauge, check valve and various control valves and pipes. The water supplied by the pump pressure, the foam liquid according to a certain proportion after the replacement of water and pressure device mixed into the foam mixture, the capsule will be separated from the foam liquid with water, foam once did not run out, you can continue to use and mixed precision stable reliable next time.
The utility model has the advantages of large flow pressure range and small pressure loss, and is widely used in various high, medium and low multiple foam extinguishing systems. According to the structure can be divided into two types of horizontal and vertical.
Two, working principle
When the fire pressure water through the device, the proportional mixer according to the proportion of shunt, one part of the water tank into the foam sandwich, capsule capsule is squeezed out, the replacement of the foam mixture volume of foam liquid with the rest of the pipeline for a certain proportion of the mixed water, and delivered to the foam generating device
