본 발명은 역수 방지밸브에 관한 것으로, 더욱 상세하게는 그 목적은, 역수 방지밸브의 완벽한 지수를 위하여 원판 디스크 상에 무게추를 설치하도록 하는 역수 방지밸브에 관한 것이다.The present invention relates to a backwater check valve, and more particularly, to a backwater check valve for installing a weight on a disc for the perfect index of the backwater check valve.

일반적으로, 우천시의 집중호우로 인하여 하천 및 강 수위가 상승하여 시가지 및 주택가가 침수되어 많은 인명 및 재산피해 등 재난이 자주발생하게 되는데, 이러한 문제를 해결하기 위하여 펌프장의 토출배관 또는 우배수관로 말단에 역수방지밸브를 설치하여 하천 및 강물이 역류하는 것을 방지하고 있다.In general, due to the heavy rains in rainy weather, rivers and rivers rise, flooding urban areas and residential areas, and many disasters such as many lives and property damages occur. A backwater check valve is installed in the water to prevent backflow of rivers and rivers.

도 1은 종래에 따른 역수 방지밸브를 나타낸 단면도이다.1 is a cross-sectional view showing a conventional water check valve.

도시된 바와 같이 역수 방지밸브는, 일측단에 토출배관(3)과 연결 설치되는 플랜지(1a)가 형성되고, 타측단의 상단에 힌지(1c)가 결합되는 고정브라켓트(1b)가 형성된 밸브몸체(1)와, 상기 밸브몸체(1)의 고정브라켓트(1b)에 힌지(1c) 결합되는 원판형 디스크(2)로 구성되어 있다.As shown in the figure, the backwater prevention valve has a flange 1a formed at one end thereof and connected to the discharge pipe 3, and a valve body having a fixing bracket 1b at which the hinge 1c is coupled to the upper end of the other end thereof. (1) and a disk-shaped disk 2 which is hinged to the fixing bracket 1b of the valve body 1.

상기와 같이 구성된 종래의 역수 방지밸브는, 펌프(미도시)의 토출배관(3)에서 배수가 이루어지면, 역수 방지밸브는, 배수에 의한 수압으로 인하여 밸브몸체(1)에 설치된 원판형 디스크(2)가 힌지(1c)를 중심으로 회동되어 유로를 개방시켜 물을 강물이나 하천으로 배수하게 된다.In the conventional reverse water check valve configured as described above, when the water is discharged from the discharge pipe 3 of the pump (not shown), the reverse water check valve is a disk-shaped disc (1) 2) is rotated around the hinge (1c) to open the flow path to drain the water into the river or river.
