CHECK VALVE
PROBLEM TO BE SOLVED: To provide a check valve for a drain hole of a manhole or the like capable of easily stopping or recovering a function of the check valve.SOLUTION: A check valve 11 comprises: a main body case 13 which is cylindrical, in which a male screw part 18 is formed along an outer circumference, and which includes a first flange part 19 expanded outside and a second flange part 24 expanded inside in an upper portion and is threaded with a concrete integrated component; a filter member 14 which is disposed in a lower portion of the main body case; a valve 15 which is disposed so as to be freely idled inside of the main body case, has a semi-spherical shape, and is filled with a foam material 27 for buoyancy therein; a packing 16 which is provided annular along an edge of the second flange part and to which the valve can be adhered; and a cover member 17 which can be positioned in an upper portion of the packing, separated from the packing, and disposed so as to perform drainage or tightly disposed in a water cutoff state.SELECTED DRAWING: Figure 3
【課題】逆止弁の機能を簡単に停止し又は復帰できるマンホール等の水抜き孔の逆止弁を提供する。【解決手段】逆止弁１１は、筒状で外周に沿って雄ネジ部１８が形成され、上部に外側に張り出した第１フランジ部１９と内側に張り出した第２フランジ部２４とを有し、コンクリート一体部品に螺着される本体ケース１３と、本体ケースの下部に配設されるフィルター部材１４と、本体ケースの内部に遊動自在に配設され半球形で内部に浮力用の発泡材２７が充填されるバルブ１５と、第２フランジ部の縁部に沿って環状に設けられバルブが密接可能なパッキン１６と、パッキンの上部に位置し、当該パッキンに対して離隔して排水可能に配設され又は密着して止水状態に配設できるカバー部材１７とから構成される。【選択図】図３
