Dongyue Fire foam Tank Horizontal Pressure foam Tank PHYM foam Tank Directly Supplied by the Manufacturer

Description :

　　The pressure type foam proportioning device is mainly composed of a foam liquid pressure storage tank and a PHY type pressure type proportioner made by using the Venturi principle. When the water flow in the system pipe network passes through the pressure reducing orifice plate of the proportioner, a pressure difference will be formed before and after the orifice plate. Part of the water (3% or 6%) at the high pressure enters the foam tank through the water inlet pipe of the foam tank and is squeezed. The foam liquid in the tank is squeezed through the liquid outlet pipe of the foam tank to the low pressure of the proportioner and mixed with water to form foam mixture. The foam mixture formed is output to the foam generation equipment (medium, low and high expansion foam generators, foam guns, foam monitors, etc.) and mixed with air to produce foam for extinguishing. Part of the water enters the water chamber of the storage tank through the "water inlet valve" pipe and is squeezed. Because of the small pressure difference before and after the nozzle, the foam liquid in the tank is squeezed out through the suction pipe and mixed with water to form foam mixed liquid flow is sprayed with foam through the air foam generator or other spraying equipment to extinguish the fire. There is a rubber in the storage tank to separate the water from the foam liquid. After each use, the water in the tank and the foam liquid cannot be mixed to keep the performance of the original foam liquid unchanged, which can be used continuously to avoid the waste of foam liquid

　　The pressure type foam proportioning device will be configured with different models according to different application environments. According to its use, it is mainly divided into vertical foam proportioning device, horizontal foam proportioning device and mobile foam proportioning device.

　　1 The foam tank has stable mixing ratio and high reliability, and can provide high-quality foam mixture.

　　2. The pressure drop of foam tank is small, and the sprayed foam extinguishing agent has large energy and strong penetration ability. Can quickly extinguish fires.

　　3. Save foam liquid and reduce fire extinguishing cost. Because foam tank separates foam liquid from water, foam liquid is not used up at one time, and can be used again next time, and the mixing precision is stable and reliable.

　　4. It has a wide scope of application, and can be used for high, medium and low expansion foam extinguishing agents. Automatic foam extinguishing system foam proportioning device can use both foam sprinkler and sprinkler.
