HIGH DIFFERENTIAL PRESSURE CONTROL VALVE USING LAMINATION-TYPE DISC FOR MARINE PLANT

摘要

PURPOSE: A high differential pressure control valve for an offshore plant using multiple loaded discs is provided to improve pressure reducing effects by increasing the energy loss of fluid flowing in a disc body. CONSTITUTION: A high differential pressure control valve for an offshore plant using multiple loaded discs includes a disc body (40) formed by piling up multiple discs (10). Multiple first flow path grooves (21) are formed on one surface of each disc in multiple rows and are separated from each other. Multiple second flow path grooves (31) are formed on the other surface of each disc in the radial direction of the disc and are separated from each other. The second flow path grooves connect the first flow path grooves to each other.
