Study on Blocking Problem of Control Valve

Accompanying the automation of oil-pipeline, the control valve has been widely used in this area as a common regulating device. But the valve is easily blocked, thus increasing energy consumption and leading to great economic lose. This paper takes the blocking problem happened at a pump station of Yong-Hu-Ning import oil pipeline as a sample, and introduces the structure, working principle, flow characteristic and operating condition of the control valve in details. Then, the solution method via analysis and some suggestions are presented to prevent from the blocking problem.
