Description

Technical Field

[0001] This application relates to the field of fluid transport technology, and in particular to a pressure reducing valve intelligent adjustment structure system. Background Technology

[0002] With the acceleration of industrial automation, industrial production demands increasingly higher levels of equipment performance, control precision, and intelligence. In numerous industrial sectors such as water conservancy, agriculture, environmental protection, municipal engineering, and chemicals, precise control of fluid pressure in pipelines is crucial to ensure production safety and product quality stability. Traditional manual adjustment methods for pressure reducing valves are inconvenient and fail to meet the demands for high-precision, real-time pressure control. Intelligent adjustment systems, on the other hand, can automatically and precisely adjust pressure according to actual operating conditions, adapting to the trend of industrial automation.

[0003] In various fluid transport systems, such as farmland irrigation and urban water supply networks, pressure stability is crucial. Pressure fluctuations can lead to pipeline leaks, equipment damage, and even safety accidents. The intelligent regulating structure system of pressure-reducing valves can monitor pressure changes in real time and make rapid adjustments to ensure that the system pressure remains stable within the set range, effectively reducing safety risks caused by abnormal pressure and improving system stability and reliability.
