Abstract
본 고안은 종래의 일반적인 버터플라이밸브 내부의 몸체시트는 유체의 진행방향으로 "사다리꼴" 형으로 경사지게 형성하여 디스크의 중심선으로 볼 때에 1차편심되는 위치의 중심선에 회전축을 고정하여 회전축이 90°작동하면서 개·폐되게 하였으므로 이때에 정압측 유입측에서의 유체 압력에는 시트면에서 수밀성이 보장되지만 반대방향(역류측)에서 압력유체가 도달할 경우에는 시트면에서 누수가 되는 경우가 빈번히 발생하였으며 버터플라이밸브를 지하에 설치할 때에 몸체시트가 유체 수압에 대해 지수가 가능한 방향을 확인하고 공사를 진행해야 하나 유체의 진행방향이 바뀐 상태에서 공사를 완료하고 단수를 하려고 버터플라이밸브를 잠그면 디스크는 닫혀도 누수가 발생하므로써 다시 해체하고 배관작업을 해야 하는 등의 폐단을 해소하기 위해 버터플라이밸브 디스크의 회전축을 1차 편심한 것에서 밸브 몸체의 중심선을 기준으로 하여 상측 방향으로 간격(a)을 두고 2차 편심을 한 편심부를 가진 위치에 회전축을 고정하고 몸체시트와 개·폐되는 상·하 디스크의 접합면을 평행 경사부가 되게 형성하여 유체의 유입측 정압 뿐만 아니라 반대측의 역류수압에서도 긴밀히 밀착 차단되어 누수가 없이 하고 디스크 개폐시 디스크가 5% 이상 열린 상태에서부터 디스크와 몸체시트가 이탈된 체 개폐되므로 밸브 동작을 위한 회전력이 작아 동력의 용량도 줄일 수 있으며 패킹의 수명도 길어 경제적이며 버터플라이밸브를 매설할 때에 유체의 진행 방향을 확인하지 않고 배관 연결만 하면 될 수 있도록 고안한 것임.The present invention is a conventional butterfly valve body seat is formed in an inclined "trapezoidal" type in the direction of the fluid in the direction of the disk fixed to the center axis of the primary eccentric position when viewed from the center line of the disk to operate the rotation axis 90 ° At this time, the water pressure at the inlet side of the positive pressure is guaranteed watertightness on the seat surface, but when the pressure fluid reaches the opposite direction (backflow side), water leakage occurs frequently on the seat surface. If the body seat is installed in the basement, the body seat should check the direction in which the water pressure can be indexed and proceed with the construction.However, if the butterfly valve is locked to complete the construction and cut the water in the changed direction of the fluid, the disc will leak even if the disc is closed. To eliminate the waste, such as dismantling and piping work For this purpose, the axis of rotation of the butterfly valve disc is fixed from the primary eccentric to the position with the secondary eccentric with the secondary eccentricity spaced upward (a) from the center line of the valve body. The joint surface of the upper and lower disks is formed to be parallel inclined portions so that the fluid is tightly blocked not only at the positive pressure of the inflow side but also at the reverse flow pressure on the opposite side, so that there is no leakage and the disk and the body sheet are opened when the disk is opened more than 5% The opening and closing of the valve allows the power of the valve to be reduced due to the small rotational force for the valve operation. The life of the packing is long, so it is economical and it is designed to connect the piping without checking the direction of fluid flow when the butterfly valve is buried. One.
Description
본 고안은 버터플라이밸브의 이중 편심디스크 및 경사 몸체시트에 관한 것으로 편심된 회전축 디스크와 몸체시트의 경사면을 평행되게 형성하여 유체의 방향을 양측 어느 쪽으로 설치하든지 누수의 차단을 완벽하게 한 것이다.The present invention relates to the double eccentric disk and the inclined body seat of the butterfly valve to form an inclined surface of the eccentric rotating shaft disk and the body seat in parallel to perfectly block the leakage of water in either direction.
종래의 일반적인 버터플라이밸브 내부의 몸체시트는 유체의 진행 방향으로 "사다리꼴" 형으로 경사지게 형성하여 디스크의 중심선으로 볼 때에 1차 편심되는 위치의 중심선에 회전축을 고정하여 회전축이 90°작동하면서 개·폐되게 하였으므로 이때에 정압측 유입측에서의 유체 압력에는 시트면에서 수밀성이 보장되지만 반대 방향(역류측)에서 압력 유체가 도달할 경우에는 시트면에서 누수가 되는 경우가 빈번히 발생하였으며 버터플라이밸브를 지하에 설치할 때에 몸체시트가 유체 수압에 대해 지수가 가능한 방향을 확인하고 공사를 진행해야 하나 유체의 진행 방향이바뀐 상태에서 공사를 완료하고 단수를 하려고 버터플라이밸브를 잠그면 디스크는닫혀도 누수가 발생하므로써 다시 해체하고 배관작업을 해야 하는 등의 폐단이 있었다.The conventional body seat inside the butterfly valve is inclined in the form of a trapezoid in the direction of the fluid, and is fixed to the center line at the position of the primary eccentricity when viewed from the center line of the disc, thereby rotating the shaft 90 ° while At this time, the fluid pressure at the inflow side of the positive pressure is guaranteed watertightness on the seat surface, but when the pressure fluid reaches the opposite direction (backflow side), water leakage occurs frequently on the seat surface. When installing, the body seat should check the indexable direction against the hydraulic pressure and proceed with the construction.However, if the butterfly valve is locked to complete the construction and cut the water with the direction of fluid changed, the disc will leak even if the disc is closed. Dismantling and piping work had to be done.
본 고안은 상기와 같은 폐단을 해소하기 위해 버터플라이밸브 디스크의 회전축을 1차 편심한 것에서 밸브 몸체의 중심선을 기준으로 하여 상측 방향으로 간격(a)을 두고 2차 편심한 편심부를 가진 위치에 회전축을 고정하고 몸체시트와 개·폐되는 상·하 디스크의 접합면을 평행 경사부가 되게 형성하여 유체의 유입측정압 뿐만 아니라 반대측의 역류 수압에서도 긴밀히 밀착 차단되어 누수가 없이 하고 디스크 개폐시 디스크가 5% 이상 열린 상태에서부터 디스크와 몸체시트가 이탈된 체 개폐되므로 밸브 동작을 위한 회전력이 작아 동력의 용량도 줄일 수 있으며패킹의 수명도 길어 경제적이며 버터플라이밸브를 매설할 때에 유체의 진행 방향을확인하지 않고 배관 연결만 하면 될 수 있도록 고안한 것으로 첨부된 도면에 의해상세히 설명하면 다음과 같다.The present invention is to rotate the shaft in the position having a secondary eccentric with a gap (a) in the upward direction relative to the center line of the valve body from the primary eccentric rotation axis of the butterfly valve disk to eliminate the above closed end And the joint surface of the upper and lower disks, which are opened and closed, with the body sheet to form a parallel inclined part, so that the fluid is tightly blocked not only at the inflow measurement pressure of the fluid but also at the reverse flow water pressure on the opposite side, so that there is no leakage. Since the disc and the body seat are opened and closed from the open state more than%, the rotational force for valve operation is small, so the capacity of power can be reduced, and the life of packing is long, so it is economical, and when the butterfly valve is buried, the direction of fluid flow is not checked. It is designed to be connected only to the pipes. The.

이와같이 된 본 고안은 밸브 몸체(1)의 내부 몸체시트(2)에 회전축(4)을 구동하여 디스크(3)를 개·폐되게 작동하면 디스크(3)와 회전축(4)의 중심은 밸브 중심선(6)에서 간격(a)을 두고 편심부(7)가 되게 형성된 상태이므로 디스크(3)의 작동 궤적에 의해 디스크(3)의 전폐시 몸체시트(2) 면의 평행 경사면부(5)(5')에 밀착되어 유체면 방향은 몸체시트(2)의 평행 경사면부(5')와 유체면 역방향은 몸체시트(2)의 평행 경사면부(5) 부분에 밀착되어 역류 수압에 대해서도 완벽하게 수밀이되는 것이다.The present invention thus achieved is driven by the rotary shaft (4) to the inner body seat (2) of the valve body (1) to open and close the disk 3, the center of the disk 3 and the rotating shaft (4) is the valve center line Since the state in which the eccentric portion 7 is formed at intervals (a) at (6), the parallel inclined surface portion 5 of the surface of the body sheet 2 when the disk 3 is fully closed due to the operating trajectory of the disk 3 ( 5 '), the fluid surface direction is in close contact with the parallel inclined surface portion 5' of the body sheet 2 and the fluid surface reverse direction is in close contact with the parallel inclined surface portion 5 in the body sheet 2, so that it is perfectly resistant to countercurrent hydraulic pressure. It is to be watertight.
