Hunan balanced proportional mixing device-motor driven PHP

The series of balanced foam proportioning mixing devices uses a foam liquid pump to feed back the pressure of the pressurized foam liquid and the pressure water supply to the balance valve to automatically adjust the size of the valve switch to achieve dynamic balance. A certain amount of foam liquid and pressure water enter the proportional mixer to form a foam mixture. If the ratio between the pressure and flow rate of the water inlet pipe is unstable, the balance valve adjusts the amount of foam liquid through dynamic balance and then enters the proportional mixer to make the foam mixture proportion accurate. Foam liquid can be added during operation
to extend the fire extinguishing time< br/>Improved the ability to extinguish fires and resist disasters. It is suitable for important fire protection projects such as oil depots and docks of large petrochemical companies and offshore drilling platforms.
Working principle: The motor drives the gear pump to rotate, pressurizing the foam liquid, then enters the balance valve, and then enters the proportional mixer after being adjusted by the balance valve. When one of the pumps fails, the other backup pump automatically switches operation to maintain normal working status.
Composition: The device mainly consists of a normal pressure foam liquid storage tank, balance valve, pressure relief/
Pressure maintaining valve, safety valve, electric ball valve, foam proportioning mixer, motor foam pump unit, control cabinet, It is composed of public chassis and pipe accessories.
