Abstract

본 고안은 버터플라이밸브(BUTTERFLY VALVE)에 관한 것으로서,The present invention relates to a butterfly valve (BUTTERFLY VALVE),

특징은 고압의 유체압력이 밸브 디스크의 좌.우에 가해 질때에도 밸브 디스크가 밸브몸체 시트면에 강하게 압접되어 확실한 밀폐작용이 완벽하게 이루어지게 한데 있다.Its feature is that even when high pressure fluid pressure is applied to the left and right sides of the valve disc, the valve disc is strongly pressed against the valve body seat surface to ensure a perfect sealing effect.

Description

제수변식 버터플라이밸브{GATE VALVE TYPE BUTTERFLY VALVE}Distillation Butterfly Valve {GATE VALVE TYPE BUTTERFLY VALVE}

본 고안은 제수변식 버터플라이밸브에 관한 것으로서,The present invention relates to a butterfly valve,

종래에는 몸체시트가 도면3과 같이되어 있어 몸체시트가 원형으로 되어있는 것을 원형의 중간부를 절단하여 그 반쪽으로 기존 반쪽과 접합함으로 인해 접합되는 부분에 "△" 형의 시트가 돌출하여 밸브디스크를 닫을시 누수가 심하였고 마모가 심하였다.Conventionally, the body seat is as shown in Fig. 3, so that the body seat is circular, and cuts the middle part of the circle and joins the existing half to the half. There was a lot of leakage and abrasion when closing.

본 고안은 상기와 같은 문제점을 해결하기 위하여 도면2와 같이 좌측원주와 우측원주를 각각 커다란 각도로 대칭되게 형성하여 디스크가 개폐시 "△"형 시트부분에 돌출을 없게하여 밸브디스크를 닫을시 전혀 누수가 없게한 것으로서,In order to solve the above problems, as shown in Fig. 2, the left circumference and the right circumference are formed to be symmetrical at large angles so that the disc does not protrude in the "△" type seat portion when the disc is opened or closed at all when the valve disc is closed. As there was no leak,

위와같이 된 본 고안은 밸브몸체(1) 내부에 유체가 강하게 흐를 때 종전에는 P1.P2 양쪽에서 동일한 압력에 견딜 수 없었으며,The present invention as described above was not able to withstand the same pressure on both sides of P1.P2 when the fluid flows strongly inside the valve body (1),

또한 몸체시트(9)의 중심연결부에서 누수가 심하였으므로 밸브몸체(1) 내부에는 경사각으로 된 몸체시트(9)가 대칭으로 되어 있어 축(3)을 우회전할 시 즉 닫힐 때 몸체시트(9)와 디스크시트(5)가 강하게 접촉되어 P1.P2 어느부분에서 압력을 가해도 동일한 압력을 받게된다.In addition, the leakage of water from the central connection of the body seat (9) is severe, so the body seat (9) of inclination angle is symmetrical in the valve body (1) when the shaft (3) is turned to the right, that is, when the body seat (9) is closed. And the disk sheet 5 are in strong contact with each other, and the same pressure is applied to any part of P1.P2.

또한 디스크시트(5)가 정확히 고정되지 않았을시는 디스크시트 누르개(2)를 볼트(7)로서 조우면 된다.When the disk sheet 5 is not fixed correctly, the disk sheet clamp 2 may be tightened with the bolts 7.

고안의 구성 및 작용 누락Missing composition and action of the devise

이와같은 본 고안은 관로내의 고압의 유체가 P1.P2에 가하여도 동일한 압력에 견딜수 있으며, 디스크(6)가 커다란 각도로 경사면으로 형성되어 있어 디스크(6)가 90。를 초과하지 아니하여 기어박스가 고장이 나도 디스크(6)가 절대 이탈하지 않는 효과가 있다.The present invention can withstand the same pressure even when the high-pressure fluid in the pipeline is applied to P1.P2, and the disk 6 is formed at an inclined surface at a large angle so that the disk 6 does not exceed 90 ° so that the gearbox does not exceed 90 °. Even if a failure occurs, there is an effect that the disk 6 never leaves.
