Дослідження впливу поворотної заслінки на гідродинамічний режим нафтопроводу

Abstract

The article discusses the positive aspects of the using a butterfly valve to control the outlet pressure of the oil pumping station. Also it emphasizes the importance of the pressure control in oil pipeline to ensure its safe operation. The dependence of the differential pressure on the butterfly valve position, which was experimentally obtained in the oil pipelines in operation, is also analyzed in this article. The uneven impact of butterfly valve on the hydrodynamic regime of the main oil pipeline is demonstrated. The article points out the need to change velocity of the butterfly valve rotary especially in the inefficient and too large throttling areas.
