Pressure Type Proportioning Mixing Device
1.Continuous Supply: Foam concentrate replenished during operation, breaking traditional limits for long-term large-scale fire fighting.
2.Sufficient Storage: Larger space avoids replenishment interruption, boosting emergency reliability.
3.Stable Operation: Optimized structure ensures accurate mixing ratio, unaffected by pressure fluctuations, with controllable fire effect.
4.For Large Projects: Designed for high-risk scenarios (petrochemical, crude oil terminals), compensating for traditional device flaws.
5.Efficient Fire Extinguishing: Rapid high-quality foam coverage blocks fire, enhancing efficiency significantly.
6.Wide Applications: Fits logistics warehouses, substations, adapting to various flammable media.
Product Introduction
The vertical PHYM series and PHYML series pressure type propor-tional mixing device consists of foam storage tank,capsule,pressure type proportional mixer,safety valve,control valve and some auxiliary parts.When the fire pressure water flows through the device,the proportional mixer divides it proportionally.A small part of the water is immersed in the interlayer of foam solution storage tank with capsule,extrudes the capsule,and the replaced foam liquid is mixed with the fire water of other main pipes to form a certain proportion of foam mixture,And output to foam generator or other foam injection equipment.PHYML series pressure proportioning mixing device is suitable for mixing 3%or 6%foam liquid.
