Abstract
Description
Claims (1)
- 밸브 내부의 유체출구측에 유체누설로 인해 발생하는 파를 음향감지수단에서 감지하여 증폭기에서 증폭하여 제어유니트에 입력하여 분석함에 의해 밸브 내부의 유체출구측의 유체 누설량을 감지하는 밸브의 유체누설 감지장치에 있어서,상기 음향감지수단과 증폭기 사이에는 이 음향감지수단에서 감지된 신호가 노이즈의 영향을 받지 않도록 이 신호를 반파정류하는 전치증폭기(Preamplier)가 연결되어 있고,상기 음향감지수단은 유체출구측의 밸브몸체부 외부벽에 용착된 전달봉과, 상기 전달봉의 단부에 결합된 음향센서로 이루어져 있는 것을 특징으로 하는 밸브의 유체누설 감지장치.
