- 유체가 유동 되는 밸브몸체 내부에 구비되며, 원통형상으로 외측에는 복수개의 유동구멍이 n등분된 위치에 상태로 플러그의 상하 이송에 따른 개폐 정도에 따라 유량이 조절되도록 순차적으로 배열된 컨트롤 밸브의 케이지 제조방법에 있어서,상기 케이지의 최하측 유동구멍의 개수를 선정하는 단계와;상기 컨트롤 밸브의 사양에 따라 유량계수(Cv)를 산출하는 단계와;상기 케이지의 최하측 유동구멍의 개수와 상기 유량계수(Cv)를 이용하여 상기 케이지에 형성된 상기 유동구멍의 총단면적(Amax)을 산출하는 단계와;상기 케이지를 길이방향으로 n등분 분할하는 케이지 분할 단계; 및상기 케이지 분할 단계의 n등분 분할 위치중 하측에서 m번째 등분 위치까지의 모든 유동구멍의 총단면적 Am = Amax еc(x-1) 인 복수개의 제 m번째 유동구멍을 형성하는 유동구멍형성단계를 포함하고,상기 총단면적(Am)의 c는 컨트롤 밸브의 유동특성에 따라 정해지는 상수를 의미하며, 상기 총단면적(Am)의 x는 유동구멍의 개방단계에 따른 개방정도를 나타내는 것을 특징으로 하는 컨트롤 밸브의 케이지 제조방법.
- 제 1항에 있어서,상기 케이지의 최하측 유동구멍은, 밸브의 손상을 가져오는 케비테이 션(Cavitation)이나 플러싱(Flushing)을 방지할 수 있도록 적어도 3개 이상을 형성하는 것을 특징으로 하는 컨트롤 밸브의 케이지 제조방법.
- 삭제
- 제 1항에 있어서,상기 유동구멍은, 제 m번째 등분 위치에 형성된 유동구멍과 제 m+1번째 등분 위치에 형성된 유동구멍의 사이간격이 각 유동구멍의 반지름의 합보다 작은 값으로 가지며, 상기 케이지의 길이방향에 대하여 나선방향으로 형성되는 것을 특징으로 하는 컨트롤 밸브의 케이지 제조방법.
- 제 1항에 있어서,상기 유동구멍형성단계는,상기 케이지 하측에서 m번째 등분 위치까지의 모든 유동구멍의 총 단면적(Am)을 첫번째 등분된 위치에 형성된 유동구멍의 총 단면적(A1′)에서 m번째 등분된 위치에 형성된 유동구멍의 총 단면적(Am′)까지의 합으로 나타내며, m번째 등분 된 위치에 형성된 유동구멍의 총 단면적(Am′)은 Am′= Am - (Am-1)로 산출되는 것을 특징으로 하는 컨트롤 밸브의 케이지 제조방법.
