Claims (1)
- 弁箱の下流側の上部に流体の流れ方向に対して直交する水平な弁軸が支持され、この弁軸に円板状のフラップ形弁体の上端部が揺動自在に取り付けられており、フラップ形弁体の揺動により、フラップ形弁体の弁面が弁箱の下流側開口の弁座面に対して離着座して弁箱の下流側開口を開閉するものにおいて、フラップ形弁体と共に押下されることにより弁箱に圧入される弁軸固定部材が弁軸に取り付けられており、弁軸の中心軸からフラップ形弁体の押下面及び弁軸固定部材の押下面までの距離が同一に形成され、弁軸固定部材が圧入される弁箱の圧入先端面が弁箱の下流側開口の弁座面よりも上流側に形成されていることを特徴とする逆止弁。
