Claims (2)

  1. 원판형상의 밸브체를 일체로 회전축으로 회전시켜, 이 밸브체의 외주 접촉부를 밸브본체의 관통구멍의 시이트링과 접촉분리하여 개폐하도록한 버터플라이밸브에 있어서, 상기 밸브체의 외주접촉부에서 상기 회전축의 적어도 축방향부근의 시일면적을 다른 시일 면적보다도 좁게 형성한 것을 특징으로 하는 버터플라이 밸브.
  2. 제1항에 있어서, 축방향 부근의 시일면적을 좁게하기 위하여, 밸브체의 외주 접촉부의 일부에 잘린부분을 형성하도록한 것을 특징으로 하는 버터플라이 밸브.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
