Abstract
Description
・ バタフライ弁が回転するたびにシールが動的なシートを擦るという理由で、バタフライを作動させるのに必要なトルク;
・ この摺動摩擦に起因した接触面の早期摩耗、および、
・ 現在の材料の物理的限界であり、その理由は、これが、特に、バタフライの閉じた運動学のせいで、材料の引き裂きを伴わずにシールが高い圧縮レベルを受けるのを可能にしないからであり;これは、許容動作圧への制限をもたらす。
Claims (10)
- ・環状の内部シートによって、軸方向の通路を形成する内部エリアを画定するボディ(2)と、
・前記ボディ(2)の内側で、前記通路を露呈する開位置から前記通路をカバーする閉位置まで回転する能力を備えて実装された中心決めされたバタフライ(1)と、
・前記シートと、前記閉位置で前記シートに対向する前記バタフライの面と、によって境界決めされるハウジング内に配置されたシール(3)と、
を含み、前記シートおよび前記面が前記軸方向に沿って内側に向けて互いに近接する、弁であって、
前記閉位置において、前記シール(3)は、その全体が、前記ハウジングの内側で全方向に自由に動く、ことを特徴とする弁。 - 前記シール(3)を変形せずに動けるようにすることのみによって、前記ハウジングから離れるのを防止する手段を備えることを特徴とする請求項1に記載の弁。
- 前記手段は、放出防止リング(4)であることを特徴とする請求項2に記載の弁。
- 前記手段は、前記ボディ(2)の内側の円周溝であることを特徴とする請求項2に記載の弁。
- 前記軸方向のハウジング寸法は、前記軸方向のシール寸法(3)よりも、前記軸方向の前記シール寸法の1〜50%の間だけ大きいことを特徴とする請求項1から4のいずれか一項に記載の弁。
- 前記軸方向の最大寸法は、前記ハウジングの任意の他の位置よりも前記内側から最も遠い前記ハウジング上の位置にあることを特徴とする請求項5に記載の弁。
- 前記軸方向に垂直な径方向のハウジング寸法は、前記径方向のシール寸法(3)よりも、前記径方向の前記シール寸法の1〜50%の間だけ大きいことを特徴とする請求項1から6のいずれか一項に記載の弁。
- 前記径方向の最大寸法は、前記ハウジングの任意の他の位置よりも前記内側から最も遠い前記ハウジング上の位置にあることを特徴とする請求項7に記載の弁。
- 前記シール(3)は、Oリングまたはリップ・シールであり、好ましくは、弾性コア(6)によって付勢されることを特徴とする請求項1から8のいずれか一項に記載の弁。
- 前記閉位置の前記バタフライの両側に2つのシール(3)が備え付けられることを特徴とする請求項1から9のいずれか一項に記載の弁。
