【実用新案登録請求の範囲】[Scope of utility model registration request] 環状の弁座を備える本体内に、該弁座に接離する２枚の
板状弁体を軸支し、該弁体をスプリングの張力と背圧で
閉止させて流体の逆流を阻止するようにした逆止弁にお
いて、弁体に突起を形成し、該突起に衝接して弁体を開
弁方向へ移動させ得るネジ棒を本体に進退自在に螺挿し
たことを特徴とする逆止弁。Two plate-shaped valve bodies that come into contact with and separate from the valve seat are pivotally supported in the main body having an annular valve seat, and the valve bodies are closed by spring tension and back pressure to prevent backflow of fluid. A check valve characterized in that a protrusion is formed on the valve body, and a threaded rod that can move the valve body in the valve opening direction by colliding with the protrusion is screwed into the main body so as to be freely retractable. .
