본 고안은 관체의 단부 토출구에 취부하여 자동으로 역류를 방지하도록 한 역수방지 밸브의 누수방지용 디스크에 관한 것이다.The present invention relates to a disc for preventing leakage of a backwater check valve mounted on an end outlet of a tubular body to automatically prevent backflow.

종래의 역수방지 밸브는 관체의 단부에 비금속제 시트를 장착하고 밸브디스크의 내측 시트와의 접합면에 수도용 고무판을 절단하여 볼트로 취부고정하여 밸브 디스크의 중량과 수압에 의해시트에 밀착시켜 역류를 방지하게 구성하므로써 초기에는 지수가 가능하나 장기간 사용하면 밸브디스크가 시트에 닫혀질 때에 발생하는 충격에 의해 볼트가 풀려지거나 하면 부착한 수도용 고무판은 이완되어 역압에 의해 누수가 되므로써 관체로 역수가 되는 등의 폐단이 있었다.Conventional backwater check valves are equipped with non-metallic seats at the end of the pipe, cut water rubber plates on the joint surface with the inner seat of the valve disk, fix them with bolts, and adhere to the seat by the weight of the valve disk and water pressure to prevent backflow. It can be indexed at the beginning because it is prevented, but if it is used for a long time, if the bolt is released due to the shock generated when the valve disc closes to the seat, the attached rubber rubber plate is loosened and leaked by the back pressure. There was a dismissal.

본 고안은 상기와 같은 폐단을 해결하기 위해 정수장이나 하수처리장에 설치한 관체의 토출구에 부착한 시트면네 착탈하는 밸브디스크의 내접합면(a) 전주위에 미가류고무를 가열 융착 코팅하므로써 펌프 운전시 유입되는 역수를 완전히 차단하여 운전저항 등 손실을 방지하면서 반영구적으로 사용할 수 있도록 고안한 것으로 첨부된 도면에 의해 상세히 설명하면 다음과 같다.The present invention is designed to solve the above-mentioned shortcomings by heating and fusion-coating unvulcanized rubber around the inner joint surface (a) of the valve disk to be attached and detached to the seat surface attached to the discharge port of the pipe installed in the water purification plant or sewage treatment plant. It is designed to be used semi-permanently while completely blocking the incoming reciprocating water to prevent loss such as driving resistance when described in detail by the accompanying drawings as follows.

밸브본체(1)의 단부시트(2)에 밸브디스크(3)가 착탈되게 한 통상의 것에 있어서, 밸브디스크(3)의 내측 접합면(a) 전주위에 미가류고무를 가열 융착한 ""형 시트층(4)을 일체화로 형성하여서 된 것이다. 미설명 부호 "5"는 힌지핀, '6"은 볼트를 표시한다.In the usual case in which the valve disc 3 is attached to or detached from the end seat 2 of the valve body 1, the unvulcanized rubber is heated and welded around the inner joining surface a of the valve disc 3. Is formed by integrally forming the " type sheet layer 4. " 5 " denotes a hinge pin, and " 6 " indicates a bolt.

이와같이 된 본 고안은 양수장이나 하수처리장 등의 저수조에 설치한 상태에서 가동을 하면 유입수는 관체와 밸브본체(1)를 통해 통상과 같이 밸브디스크(3)를 밀어 올리면서 저수조로 계속 유입되다가 펌프의 가동을 중지하면 밸브디스크(3)의 내접합면(a) 전주위에 미가류고무를 가열 일체화로 융착한 ""형 시트층(4)과밸브 디스크(3)가 자체 중량과 수압에 의해 시트(2)방향으로 이동하면서 시트(2)에 충격을 주지 않으면서 유체중에서도 전혀 변형이 되지 않으므로 반영구적으로 완벽하게 누수를 차단하여 운전 저항 등의 손실을 방지할수 있는 효과가 있다.The present invention, as described above, is operated when installed in a reservoir such as a pumping station or a sewage treatment plant, the inflow water continues to flow into the reservoir while pushing up the valve disc 3 through the pipe body and the valve body 1 as usual. When the operation is stopped, the unvulcanized rubber is fused by heating and integrated around the inner surface (a) of the valve disc (3). The semi-permanently leaks because the "type seat layer 4 and the valve disc 3 move in the seat 2 direction by their own weight and water pressure, and do not deform at all in the fluid without impacting the seat 2. Blocks the effect of preventing the loss of driving resistance.
