The Development Trend of Control Mode of Valves
Modern operating systems are becoming more and more diverse and complex, so the valves used in them also involve various control formats. The development trend of valves and control methods can be summarized as follows:
1. Intelligentization: As the intelligence of the valve control program deepens, the joint control with other systems is more flexible, and the convenience and accuracy of valve control are greatly improved. Each valve is equipped with fieldbus technology, which further facilitates the linkage between valves, which has laid the foundation for highly integrated and automated operating system controls.
2. Networking： Now the whole world is connected by a deep network, and the pressure of network competition is becoming more and more intense. The demand for valves has gradually shifted from central control to local decentralized control. With the help of network technology, the valves in the control system are basically connected with each other to realize intelligent management.
3. Human-computer Interaction: From the early purely manual control to the later mixed manual and automatic control, and then to the current intelligent control, the development of valves has gone through different stages. The recent emergence of human-computer interaction has made the operation of the valve control system more intuitive and convenient, greatly increasing the stability and reliability of the control system.
4. Intelligence empowerment: With the arrival of the Internet of Things, intelligence will become more and more precise. The traditional valve control system is being waved into the era of intelligent empowerment. The valves will be equipped with intelligent components according to different needs, with functions such as on-line self-diagnosis to realize fault diagnosis of the entire valve pipeline.
5. High-reliability Environment: The reliability of valve control is gradually improving. More and more components are added to valves which are highly reliable and long-life, such as corrosion resistance, rust resistance and wear resistance, making them ideal for use in high-reliability environments.
In conclusion, valves and the corresponding control methods have experienced tremendous development. Through intelligence, network communication, human-computer interaction and other elements, valve control is gradually entering the era of intelligence, so that the valve is constantly close to its own optimization. At the same time, the Internet of Things will also be a powerful engine to drive the development of valve control technology, injecting new vitality into this field.
