Hunan balanced proportional mixing device-turbine 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 valve switch size 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.
Composed of atmospheric foam liquid storage tank, balance valve, safety valve, stop valve, one-way valve, double-needle pressure gauge, foam liquid pump, foam proportioning mixer, turbine, filter, public chassis and pipeline accessories, etc. composition.
Working principle: The hydraulic turbine is used to drive the foam liquid pump, which can automatically adjust the pump speed according to the system pressure to adjust different foam liquid volumes. At the same time, the balance valve is also adjusted to ensure that the foam mixture ratio accurately meets the design requirements.
