1. Structure and Performance
The Remarkable Role of Self-Operated Flow Control Valve is ingeniously crafted to ensure a steadfast and constant flow through the valve even amidst the fluctuations in pressure difference between the inlet and outlet of the valve. This innovation guarantees the continuous flow of the controlled entity, be it a loop, a user, a device, or others linked in series. The self-operated flow control valve boasts a variety of aliases, including self-operated flow balance valve, fixed flow valve, self-balancing valve, and dynamic flow balance valve These diverse self-operated flow control valvesmay vary in structural design, yet their underlying working principles remain consistently admirable.
2. Structure and Working Principle
The self-operated flow control valve s, from a structural perspective, is essentially a double valve system, comprising both a manual regulating valve section and an automated balancing valve section, as beautifully illustrated in Figure 1. The manual regulating valve section adeptly sets the desired flow rate, while the automatic balancing valve section ensures the flow rate remains impressively constant.
The self-operated flow control valve within the manual control valve section follows the flow G=P2-P3 equation. Here, Kv represents the flow coefficient of the manual control valve port, with P2-P3 indicating the pressure differential across the manual control valve port. The Kv value remains steady as long as the opening is fixed, hence maintaining an unchanging flow G when P2-P3 remains stable. The automatic balancing valve section expertly manages P2-P3's stability. For instance, should the inlet and outlet pressure differential P1-P3 increase, the automatic balancing valve section adjusts by reducing through the pressure sensing film and spring mechanism, thus increasing P1-P2, all to preserve P2-P3's constancy; Conversely, a decrease in P1-P3 prompts the automatic balancing valve section to expand, reducing P1-P2 yet maintaining a constant P2-P3.
Each Opening of the Manual Control Valve Each valve group in our series is meticulously calibrated to correspond to a specific flow rate, with the relationship between valve opening and flow rate finely tuned through rigorous test bench evaluations. This ensures precise control, featuring an opening display for real-time monitoring and a secure locking device to maintain desired settings.
3. Performance and Features
1. Our cutting-edge valve system allows you to preset flow rates according to design specifications or real-world needs, automatically compensating for pressure fluctuations. This ensures a consistent flow, revolutionizing system stability.
2. Experience uniform heating and cooling like never before, as our advanced technology overcomes temperature disparities in the system, significantly enhancing thermal quality.
3. Effortlessly address the challenge of large pressure differentials: our solution balances the extremes-high pressure near the source and low pressure at the far end-ensuring seamless performance.
4. By minimizing system circulation water and resistance, our valves contribute to a more efficient system operation, translating to cost savings and sustainability.
5. Simplify your design process with our valves that eliminate the need for complex hydraulic balance calculations of the pipe network, reducing design workload significantly.
6. Transform the intricate task of network adjustment into a straightforward flow distribution, reducing the complexity and enhancing ease of use.
7. Seamlessly adapt to changes in heat sources within multi-source pipe networks without the hassle of flow redistribution, thanks to our innovative design.
8. Enjoy peace of mind with our valves, as flow display values are precisely calibrated on the test bench, ensuring accuracy in flow measurement (m3/h).
4. Technical Parameters
1. Our valves operate efficiently within a medium temperature range of 0-150ºC and handle a working pressure difference of 20-600Kpa. They can be selected based on the pipeline's equal diameter, providing versatile options to suit your needs.
2. Select the perfect valve based on your system's maximum flow rate and within our wide flow range, ensuring optimal performance and fit. Efficiently engineered to meet your specific requirements..
5. Installation and Commissioning
1. Ensure that the flow direction of the medium aligns with the valve body's designated arrow;
2. After installation, adjust the flow rate to meet the demands of the pipeline's series;
3. Verify that the pressure difference between both ends of the valve falls within the specified working pressure range;
4. Strive to prevent the valve from operating in a minimal flow state;
5. As there is no blowdown screw on the spring cover, ensure regular blowdown maintenance.
6. Adhere to the standard
