본 고안은 수원지등의 대구경수도관에 사용되는 버터프라이 밸브를 개량하여 밸브의 개폐작용이 원활하게 이루워지도록 함과 동시에 부관변의 밸브시트와 디스크링의 마모율을 감소시키고, 부관변의 위치변화를 방지하여 밸브의 사용수명을 연장시키며 누수방지효과를 향상시키도록 하기 위한 것이다.The present invention improves the butterfly valves used in large diameter water pipes such as water sources to facilitate the opening and closing of the valves, and at the same time reduces the wear rate of the valve seats and discrings on the side pipes and prevents the side valves from changing position. It is to extend the service life of the valve and to improve the leak prevention effect.

종래 구경이 큰 수도관에 버터프라이 밸브를 장설함에 있어서는 밸브의 개폐작동을 용이하게 하기위하여 메인벨브에 부관변을 형성하게 되는 것인바, 일반적으로 제4도에 도시하는 바와 같이 부관변의 회동측이 메인밸브 화동축의 내부중간 위치까지 동심축으로 삽입되게 형성하므로서, 부관변의 회동축을 지지하는 스라스트베어링(thrust bedring)이 부관변의 개폐에 따라 메인밸브의 회동축과 접촉마찰을 이르키게 되는 것이어서, 스라스트베어링의 마모가 빨리 진행되는 것이고, 이에따라 부관변의 변위(變位)오 차가 크게 발생하여 누수현상이 나타나게 됨과 동시에, 부관변의 변위로 발생된 간극으로부터 고압수가 분출됨에 따라 분출되는 물과의 마찰로 부관변의 벨브시이트 및 디스크링이 마모 또는 변형되어 밸브의 기능을 저하시키게 되는 원인이 되었던 것이다.In installing a butterfly valve in a water pipe having a large diameter in the related art, in order to facilitate opening and closing of the valve, a sub-pipe side is formed in the main valve. As shown in FIG. The thrust bedring supporting the pivot shaft of the sub-pipe side is brought into contact with the pivot shaft of the main valve according to the opening / closing of the sub-pipe side, by being formed to be inserted concentrically to the internal intermediate position of the valve shaft. The wear of the thrust bearings proceeds rapidly, and the displacement error of the secondary side is large, resulting in water leakage. Causes the valve seat and disc ring on the secondary side to wear out or become deformed, thus reducing the function of the valve. It would have been.

본 고안은 이와 같은 종래의 결점을 제거하기 위하여 부관변의 회동축을 메인밸브 회동축의 하단부까지 연장돌출 시킴으로서 부관변의 회동측을 지지하는 스라스트베이링을 메인밸브 회동측의 외부에 설치하여 메인밸브를 개폐할때에는 부관변의 스라스트베어링이 접촉마찰되지 않도록한 것으로서 이하도면에 따라 상세히 설명하면 다음과 같다.The present invention extends the subsidiary rotation shaft to the lower end of the main valve rotation shaft in order to eliminate such a conventional defect, and the thrust bearing is installed outside the main valve rotation side to support the rotating side of the sub valve side. When the opening and closing the thrust bearing of the sub-legal side to prevent contact friction as described in detail as follows.

밸브로드(1)의 회동으로 개폐되는 메인디스크(2)의 중앙부에 형성된 통수공(3)을 부관변(4)에 의하여 개폐하도록 된 것에 있어서, 밸브로드,(1)의 중심을 관통하는 부관변(4)의 회동측(5)을 밸브로드(1)의 하단부까지 연장돌출시키고, 부관변(4)의 회동축(5)을 지지하는 스라스트베어링(6)을 밸브로드(1)의 외부에 설치하여서된 것이다.The part which penetrates the center of the valve rod 1 by opening and closing the water supply hole 3 formed in the center part of the main disc 2 which opens and closes by the rotation of the valve rod 1 by the side pipe side 4. The thrust bearing 6 supporting the pivot shaft 5 of the sub-pipe 4 is extended to the lower end of the valve rod 1 by extending the pivot side 5 of the tube 4 to the lower end of the valve rod 1. It was installed outside.

도면중 부호 7은 벨브시이트이고, 8은 디스크링이다.In the figure, 7 is a valve seat, 8 is a disc ring.

이와 같이 구성된 본 고안은 메인디스크(2) 및 부관변(4)이 모두 닫힌 상태에서 밸브를 열어 통수하고자 할때에는 제2도에 도시한 바와 같이 우선회동축(5)을 회동시켜 부관변(5)을 열게되면 통수공(3)을 통하여 고압수가 유출되므로서 송수관내의 압력이 급격히 감소되는 것이고, 이에따라 벨브로드(1)를 회동시켜 메인디스크(2)를 용이하게 열 수 있게 되는 것이며, 단수하고자 할때에는 통수시와는 반대로 메인디스크(2)를 먼저 닫은 후에 부관변(4)을 닫게되는 것인바, 부관변(4)의 회동축(5)을 지지하는 스라스트베어링(6)은 부관변(4)을 개폐할때에 한하여 회동축(5)과 접촉 마찰하게 되는 것이고, 메인디스크(2)를 개폐할때에는 벨브로드(1)와 회동측(5)의 스라스트베어링(6)이 접촉되지 않으므로서 밸브로드(1)와의 마찰에 의한 스라스트베이링(6)의 마모율을 감소시킬 수 있게 되는 것이다.When the main disc 2 and the side pipe 4 are both open and pass through the valve, the present invention configured as described above may rotate the first pivot shaft 5 as shown in FIG. When opening the), the high pressure water flows out through the water supply hole (3), so that the pressure in the water supply pipe is drastically reduced. Accordingly, the valve rod (1) is rotated so that the main disk (2) can be easily opened. When the contrary, when passing through the main disk (2) first to close the secondary tube (4), the thrust bearing (6) supporting the pivot shaft (5) of the secondary side (4) is the secondary side Only when opening and closing (4) is in contact friction with the rotating shaft (5), when opening and closing the main disk (2) the valve rod (1) and the thrust bearing (6) of the rotating side (5) contact Wear rate of the thrust bearing 6 due to friction with the valve rod 1 It can be reduced.

따라서 밸브를 개패할때마다 회동축(5)의 스라스트베어링(6)이 종래에는 4회의 접촉마찰을 받게되던 것을 본 고안에서는 2회의 접촉마찰로 반감시킴으로서 회동측(5)의 위치 변화에 따른 부관변(4)의 작동오차를 감소시키게되는 것이고, 이에따라 누수율이 감소됨과 동시 벨브시이트(7)와 디스크링(8)이 누수시에 분출수와의 마찰로 인하여 마모 또는 변형되는 것을 방지하여 밸브의 사용수명을 연장시킬 수 있는 작용효과를 나타내게되는 것이다.Therefore, every time the valve is opened and closed, the thrust bearing 6 of the rotational shaft 5 is conventionally subjected to four contact frictions. It is to reduce the operating error of the secondary side (4), thereby reducing the leakage rate and at the same time prevent the valve seat (7) and the disc (8) from abrasion or deformation due to friction with the jetted water when the valve It will have the effect of extending the service life of the.
