3/2way 솔레노이드밸브의 성능에 영향을 미치는 설계변수 분석 = The Analysis of Design Variable Effect for 3/2Way Solenoid Valve

다국어 초록 (Multilingual Abstract)

Solenoid valves that generate hydraulic flow by using electromagnetic force are divided into spool and poppet type according to the structure.
Previous studies have focused on solenoids that supply power to hydraulic solenoid valves that use electromagnetic forces. In recent research trends, efforts have been made to improve the flow characteristics, but they are concentrated in spool valves. The poppet type valve has a tend to switch from the center of spool valve to the development of poppet valve. because of its excellent sealing power and low sensitivity to foreign matter, which is easy to operate for a long time.
In this study, the maximum pressure, the minimum pressure, and the pressure drop were examined in order to analyze the variation of the flow characteristics according to the design variables of the solenoid valve. In the research and development of the solenoid coil center, it is expected that the improvement of the flow characteristics in conjunction with the valve body can be expected to provide the valve manufacturing technology by presenting the guide when the valve body components are designed by the manufacturer.
