(One power and one water) balanced proportion mixing device

The balanced foam proportioning system is a relatively advanced large-scale foam fire extinguishing equipment in China. Our company produces the PHP series balanced foam proportioning system, which is produced according to the national standard GB20031-2005 "General Technical Conditions for Foam Fire Extinguishing Systems and Components", with advanced technology, stable quality, and wide application range. This system is mainly suitable for important fire hazard scenarios such as large petrochemical tank areas, docks, airports (warehouses), offshore oil platforms, etc.

The balanced foam proportioning system is a new type of foam fire extinguishing device that provides foam mixed liquid to the foam fire extinguishing system. The foam liquid can be replenished during the system operation, with larger storage capacity and higher reliability, and can continuously supply foam mixed liquid to the system, greatly improving the fire extinguishing ability of the system. Because the foam liquid storage tank adopts a atmospheric pressure and non-bladder design, it avoids the risk of bladder rupture, reduces maintenance costs, and reduces the cost of pressure vessels, making the device more cost-effective and better meet the needs of modern large-scale foam fire fighting projects.

The main features of the balanced foam proportioning system are:

1. The balance valve dynamically adjusts the amount of foam liquid entering the foam proportioning mixer to ensure accurate mixing ratio;

2. The foam liquid gear pump adopts stainless steel or bronze materials that are corrosion-resistant, which makes the foam mixed liquid have a wider range of working pressure and flow rate adaptability and will not rust due to the corrosion of foam liquid;

3. The foam liquid storage tank is made of atmospheric pressure, non-bladder stainless steel, fiberglass, or polyethylene material, which is easy to maintain and highly reliable;

4. The breathing valve maintains the pressure balance between the inside and outside of the foam liquid storage tank;

5. The pressure relief/retention valve and pressure relief overflow device ensure the stability of the rated working pressure of the entire system;

6. The safety valve ensures the safe discharge of the device pipeline in case of emergency;

7. The device is suitable for any foam extinguishing agent (protein, fluoroprotein, aqueous film-forming agent, etc.);

8. Foam liquid can be added at any time during the fire extinguishing process, which can better meet the needs of modern large-scale foam fire fighting projects;
