BACKFLOW PREVENTION SYSTEM OF SEWER
The present invention relates to a backflow prevention system of a sewer and, more specifically, relates to the backflow prevention system to prevent a backflow and odors flowing back to a sewer source by installing on a middle or an end part of a pipeline such as a basic sewer pipeline connected to a sump; a branch sewer pipeline connected from the sump to the sewer; and a sewer pipeline to discharge various sewage to waters such as river or sea, etc. The system comprises: a valve body; a stainless steel float; a valve upper body; a ring-shaped drainageway packing bracket; a soft drainageway packing; a band-shaped float bottom guide piece; a float ascent control piece; a float ascent guide piece; and a backflow prevention unit additionally provided on an ending portion of a sewer entrance to enable a dual system of backflow prevention.
본 발명은 하수관거의 역류 방지 시스템에 관한 것으로, 보다 상세하게는 집수정에 배관되는 기초 하수관로나, 집수정에서 하수관거로 연결되는 간선 하수관로 및 하천이나 바다 등의 공공수면에 각종 하수를 배출하는 하수관로 등의 관로 중간부나 말단부에 설치되어, 하수 배출처 측으로의 하수 역류와 악취를 방지하는 역류 방지 시스템에 관한 것이다.
