Pneumatic pneumatic - valve to ensure safe operation of oil pipeline

Crude oil long-distance pipeline is mainly to oil or crude oil wharf to refining enterprises, provide refining raw materials for refining enterprises. The particularity of crude oil pipeline process requires pneumatic - valve failure should be in a state of the position. To ensure that the crude oil pipeline in safe operation of the set pressure, using MOKVELD pneumatic regulating oil station valve to automatically adjust the pressure oil station pipeline in and out of the station and pipeline pressure wave. Analysis of the existing pneumatic - valve control principle and fault insurance scheme. Due to form a complete set of pneumatic control valve FISHER DVC6010 electrical locator itself does not have fault the position function, through the study of the increase of pneumatic control valve solenoid valve and protection module of signal transformation, realize the pneumatic - valve fault protection function. After transforming the pneumatic control valve has been successfully applied to crude oil pipeline, ensuring the safety of the pipeline running smoothly.
