Claims (3)
- 流路の一部をなす円筒状の弁箱(1)と、その流路に対し交差した弁棒(2)と、弁棒(2)を軸として回動する円板状の弁体(3)とを基本的な構成部材とし、弁箱(1)の内周には全周に亘って弁座(5)が設けられ、弁体(3)の回動に伴い、弁体(3)の外周が弁座(5)に接離して弁箱(1)内の流路を開閉するバタフライ弁において、
弁体(3)のオリフィス側となる部分の下流側に、部分球殻状の多孔板部材(7)を備え、多孔板部材(7)の貫通孔(8)を通過する流体を流路の中央側へ向かって整流すると共に、弁箱(1)のノズル側となる部分には、弁座(5)の下流側に凹球面部(10)を設け、弁座(5)と凹球面部(10)は、弁棒(2)の軸線と流路の軸線との交点を中心とする同一球面上に形成し、所定の開度以下の範囲では、弁体(3)が回動するとき、この凹球面部(10)に弁体(3)のノズル側となる部分の外周が摺接又は近接し、ノズル側で流体の流れが阻止又は抑制されるようにしたことを特徴とするバタフライ弁。 - 前記弁体(3)が、全閉時に弁棒(2)の軸線から上流側へずれた位置で弁箱(1)の弁座(5)に当接する偏心弁としたことを特徴とする請求項1に記載のバタフライ弁。
- 前記弁箱(1)の凹球面部(10)の下流側部分に、流路の流れ方向に延びる複数条のスリット(11)を形成したことを特徴とする請求項1又は2に記載のバタフライ弁。
