영어 초록
To control the flow of fluid, several kinds of valves are used. Especially, Main Control Valve (MCV) is the key element of hydraulic system which performs complex control not only controlling the flow of fluid, but also prevent damage of equipment by supplying proper hydraulic pressure to actuator and draining over-supplied hydraulic pressure. While general control valves are producing in domestically, entire quantity of main control valves are depended on importation and it depreciates competitiveness in cost, and time.
In this study, to derive the best design of notch structure by following the orifice flow of 6-linked main control valve and the relation between “notch structure” which is the most fundamental element to control the velocity of the fluid and “pressure distribution”, the flow characteristic is compared by comprehending hydraulic pressure and velocity of the fluid using CFD simulation when spool valve is used for “meter-in” and “meter-out” through the opening of the notch structure.
