Abstract
Description
그리고, 상기 피에조밸브(30)는 제어기판(40)에 연결되어 작동되며, 상기 제어기판(40)은 전원을 공급받았을 때 상기 피에조밸브(30)를 작동시켜 제어공기의 통로를 개방시키도록 미리 프로그래밍된다. 이때, 제어기판(40)에 공급되던 전원이 차단되면 피에조밸브(30)도 작동을 멈추며, 이는 레귤레이터(20)에서 공급되어 디스크(18)를 이동시키는 제어공기가 더 이상 디스크(18)를 이동시키도록 공급되지 않게 한다.
Claims (2)
- 배관에 설치되어 유체의 유로를 개폐시키도록 된 밸브와, 상기 밸브의 개도를 조절하는 액추에이터와, 상기 밸브의 개도가 적정한지를 판단하고 그 판단 결과에 의해 상기 액추에이터를 제어하도록 공압을 공급하는 포지셔너로 이루어진 밸브제어시스템에 있어서,상기 포지셔너에서 배출된 공압을 액추에이터로 공급하도록 연결된 유로와, 상기 유로를 개폐시키는 디스크와, 상기 유로를 폐쇄시키도록 디스크에 편향력을 제공하는 편향부재 및 전원이 공급되면 상기 유로를 개방시키도록 디스크를 작동시키는 피에조밸브로 이루어진 비상안전밸브를 포함함을 특징으로 하는 밸브제어시스템의 비상안전장치.
- 제1항에 있어서, 상기 비상안전밸브는 공압을 미리 설정된 압력으로 조정하여 상기 피에조밸브에 공급하도록 설치된 레귤레이터를 더 포함함을 특징으로 하는 밸브제어시스템의 비상안전장치.
