Claims (1)
- 液体が一定方向に流れる流路の底面に起伏自在に軸支され前記流路の下流側の液体が増加すると浮力によって起立して前記流路を閉止する扉体と、前記流路の内側面に貼着された戸当り部材と前記扉体の側縁部との間の漏液を防ぐため前記扉体の両側縁部に付設された側部密閉部材と、前記流路の底面と前記扉体の下縁部との間の漏液を防ぐため前記扉体の軸支部分を前記流路の上流側から覆った状態で前記流路を横断する方向に配置され前記扉体の起立動作に伴って褶曲可能な可撓性の下部密閉部材と、を備え、前記側部密閉部材の側縁部には、平板状の固定部からそれぞれ斜め上方、斜め下方に突出する上突縁部、下突縁部が固定部と一体形成され、前記下部密閉部材の側縁部に、前記流路の内側面に当接した状態で摺動可能な閉止手段を設けたことを特徴とする逆流防止ゲート。
