Abstract
【解決手段】 本体1と蓋2から成るケーシングで下部に流入口4が開口し上部に流出口5が開口した弁室3を形成する。弁室3と流出口5の間に弁座6を形成する。弁室3内に弁室3内壁との間に流路を設けた有底のほぼ円筒形状で底部に通孔11を有するフロート受け10を配する。フロート受け10内にフロート12を自由状態で配する。フロート受け10の底部に第2通孔15を設ける。第2通孔15からフロート12への流体の直進を妨げる障壁部材13を第2通孔15のフロート12側に設ける。フロート受け10内に入った外部空気が通孔11及び第2通孔15を通して素早く流入口4に流下できるので、フロート受け10内のフロート12下方の圧力が上昇することを防止でき、真空破壊能力が大きく速やかに真空破壊できる。
