The hydraulic equipments has a high utilization in the many works such as the excavation, planation and crane works in the construction sites. They are an essential equipments in the construction site and the loading & unloading works of the large size objects. In the many parts which are composed of the hydraulic equipments, the main control valve(MCV) is the core of the equipments. The hydraulic energy from the pump controls the direction and the rate of flow by MCV. And the flow rate of the MCV inlet operate some actuators to perform the diverse action of the spool. So, it is important to analysis the shape of the flow path and the notch of the spool. In order to perform the optimal design of the 6-way valve, the study for the analysis of the flow path and the pressure distribution according to the pressure control, which to meet use condition, must be performed. In this study, we carried out the reverse-engineering of the MCV using the parametric technique as the first step in the research of the MCV. And we analyzed the shape of the flow path and the pressure distribution for the notch of the spool using the optimal modeling of the MCV.

상수관망에서 다양한 제수밸브 분포간의 우열성 평가는 상수관망의 신뢰성 확보를 위해 필수적이다. 기존 상수관망에 새로운 제수밸브를 추가할 경우나 새로운 상수관망을 건설할 경우, 본 연구에서는 서로 다른 제수밸브 분포간의 우열성을 평가하여 좀 더 효율적인 제수밸브 분포를 선택할 수 있는 방법을 제안하고자 한다. 제안된 방법은 상수관 및 제수밸브의 파괴 모의를 바탕으로 하며 제수밸브 분포간의 우열성은 상수관망의 신뢰도를 기준으로 하였다. 상수관망의 신뢰도는
