Performance characteristics of flow control valves

Thread Content

A flow control valve is also known as a self-acting flow control valve, a flow balance valve, or a static balance valve. It is an intuitive and simple flow control device. When using flow control valves in piping systems, the flow rate can be set directly according to the design. Under the action of water, the valve can automatically eliminate flow variations caused by residual head and pressure fluctuations in the pipes. Regardless of how system pressure changes, the valve maintains a constant flow rate. These functions enable flow regulation in the pipeline network to be completed in one step, turning the process of regulating the network into a simple task of flow distribution, thereby effectively solving the problem of hydraulic imbalance in the pipeline network. Performance: 1. The flow rate can be set according to design requirements or actual needs, eliminating arbitrary adjustments and simplifying the complex task of network adjustment into a simple flow rate distribution process ； 2. Thoroughly eliminate uneven temperature distribution within the system to improve the quality of heating and cooling ； 3. Reduces the design workload, as there is no need for complicated hydraulic balance calculations on the piping network ； 4. Eliminate the need for multiple heat sources and the task of redistributing flow rates when switching between pipeline network heat sources ； 5. The rotor part of the flow mechanism uses agate bearings that are wear-resistant and do not rust ； 6. The transmitters and sensors on the valve body have no power supply, and the display features a fully sealed design for a long service life ； 7. Enters automatic sleep mode when not in use to save power; designed for a service life of over ten years ； 8. The display refreshes every 4 seconds, providing a smooth image. Features: The flow rate can be set according to design or actual requirements, and it can automatically eliminate fluctuations in system pressure differences to maintain a constant flow rate. Overcome uneven temperature distribution in the system and improve the quality of heating (cooling). Thoroughly resolve the issue of high pressure difference at the proximal end and low pressure difference at the distal end. Reduce the system circulation water volume to lower the system resistance. It reduces the design workload, as there is no need for complicated hydraulic balance calculations for the pipe network. Reduce the complexity of network tuning by simplifying the intricate task of network adjustment into a straightforward traffic allocation process. It eliminates the need for flow reallocation when switching heat sources in multi-source heating networks. The flow rate values are all randomly calibrated on the test bench, in units of m3/h.
