The flow control valve, also known as the self operated flow control valve, flow balance valve, or static balance valve, is an intuitive and simple flow control device. The application of flow control valves in the pipeline network can directly set the flow according to the design. The valve can automatically eliminate the flow deviation caused by the residual pressure head and pressure fluctuation of the pipeline under the action of water, and maintain the set flow rate unchanged no matter how the system pressure changes, These functions of the valve enable the flow regulation of the pipeline network to be completed at once, transforming the network adjustment work into simple flow distribution, effectively solving the hydraulic imbalance of the pipeline network.

1、 Performance of flow regulating valve

1. The flow can be set according to design or actual requirements, avoiding blind adjustment and simplifying complex network adjustment work into simple flow distribution;

2. Overcoming the phenomenon of uneven cooling and heating in the system to improve the quality of heating and cooling supply;

3. Reduce design workload and eliminate the need for tedious hydraulic balance calculations in the pipeline network;

4. Exempt from multiple heat sources and redistribute flow during heat source switching in the pipeline network;

5. The rotor part of the flow movement adopts agate bearings for wear resistance and rust resistance;

6. The valve body transmitter and sensor have no power supply, and the display adopts a fully sealed structure with a long service life;

7. Automatically sleep and save power when not working, with a designed service life of more than ten years;

8. The monitor refreshes every 4 seconds and displays smoothly.

2、 Characteristics of flow regulating valve

1. The flow rate can be set according to design or actual requirements, which can automatically eliminate pressure fluctuations in the system and maintain the flow rate unchanged.

2. Overcome the phenomenon of uneven cooling and heating in the system, and improve the quality of heating (cooling).

3. Resolve the contradiction between high pressure difference at the near end and low pressure difference at the far end.

4. Reduce the circulating water volume of the system and reduce system resistance.

5. Reduce design workload and eliminate the need for tedious hydraulic balance calculations on the pipeline network.

6. Reduce the difficulty of network adjustment and simplify complex network adjustment work into simple traffic allocation.

7. Exempt flow redistribution during heat source switching in multi heat source pipeline networks.

8. The flow display values are randomly calibrated on the test bench, with a flow rate of (m ³/ h) .
