Abstract

본 발명은 무동력 역류 방지장치에 관한 것으로서, 하수가 유입되는 유입구와, 하수가 배출되는 배출구와, 상기 배출구를 향하여 경사지게 설치되며 상기 유입구와 배출구를 연통하는 연통구를 형성하는 단턱부가 마련된 관체 형상의 몸체부와; 상기 몸체부의 내측에 회전 가능하게 힌지 결합되어 상기 연통구를 개폐하는 도어몸체와, 상기 도어몸체의 양측부에 각각 연장 형성되어 상기 단턱부와 상기 몸체부의 내벽 사이를 차단하는 한 쌍의 차단판을 갖는 개폐도어와; 상기 개폐도어에 마련되어, 수면에 부유 가능하도록 속이 빈 통 형상을 가지며, 상기 하수가 상기 배출구로 역류하면 상기 개폐도어에 부력을 발생하여 상기 연통구를 폐쇄하도록 상기 개폐도어를 작동시키는 부유체와; 상기 단턱부와 상기 몸체부의 바닥면 사이에 마련되어, 상기 유입구로부터 유입된 하수가 상기 연통구를 통해 상기 배출구로 유동하도록 안내하는 가이드를 포함하는 것을 특징으로 한다.
