일반적으로 버터플라이밸브는 관로에 연결되는 밸브 본체의 내부에 디스크가 회전축으로 회전 가능하게 설치되고, 회전축이 연결된 구동장치에 의해 디스크가 회전하여 관로를 개폐시키게 된다. 그리고 밸브 본체의 내주면과 디스크의 외주면에는 폐쇄될 때에 서로 압착되는 시트부가 구비되어 있다.In general, the butterfly valve is installed in the inside of the valve body connected to the pipeline so that the disk is rotatable with the rotating shaft, the disk is rotated by the drive device connected to the rotating shaft to open and close the pipeline. The inner circumferential surface of the valve body and the outer circumferential surface of the disk are provided with seat portions which are pressed against each other when closed.

이와 같은 통상의 버터플라이밸브는 고무재질의 시트만으로 실링을 함으로써 완벽한 누수차단을 기대하기가 어려우며, 특히 고무 시트는 시간이 경과하면서 마찰에 의한 마모가 발생되고 수밀 기능이 급격히 감소하게 된다. 따라서 시트의 수리 혹은 교체 등의 수리작업이 빈번하게 되며 이에 따른 관리비용이 과다하게 지출되는 비경제적인 문제점이 있었다.Such a conventional butterfly valve is difficult to expect a perfect leak blocking by sealing only the rubber seat, in particular, the rubber seat is abrasion due to friction over time and water tight function is sharply reduced. Therefore, the repair work such as repair or replacement of the sheet is frequent and there is an uneconomical problem that excessive management costs are expended accordingly.

상기와 같은 고무재질의 시트가 지닌 문제점을 해결하기 위한 종래의 기술로서, 본 발명인에 의하여 출원등록된 '메탈시트 버터플라이 밸브(대한민국 실용신안등록 번호 제20-0341374호)'가 있다.As a conventional technology for solving the problems of the rubber sheet as described above, there is a 'metal seat butterfly valve (Korean Utility Model Registration No. 20-0341374)' filed by the present inventors.

상기 종래의 메탈시트 버터플라이 밸브는 밸브본체의 보디시트에 밀착된 디스크를 개방시에 디스크를 약간 수평이동시켜 디스크의 디스크시트를 금속제의 보디시트에서 떨어지게 한 후 디스크를 회전시켜 열 수 있게 한 것으로서, 디스크시트와 보디시트의 마찰마모를 크게 감소시켜 사용수명을 오래 유지시킬 수 있도록함과 아울러 밸브시트를 강하게 접촉시켜 누수차단효율을 향상시킬 수 있도록 한 메탈시트 버터플라이 밸브에 관한 것인 데, 제시된 도 4를 참고하여 보다 구체적으로 살펴보면, 금속제의 보디시트(2)를 고정한 밸브본체(1)의 관로(3)에는 디스크시트(5)를 고정한 디스크(4)를 디스크개폐축(6)으로 축설하고 상기의 디스크개폐축(6)에는 웜휠(7)을 고정하여 케이싱(8)의 측부에 핸들(10)을 부착시킨 웜(9)과 치합시켜 디스크(4)를 개폐시킬 수 있도록 한 것에 있어서 디스크(4)의 상하부에는 축끼 움구멍(401)을 형성한 ┌ ┐형의 축받이(4')를 형성하여 디스크개폐축(6)을 끼워 축설하되 축받이(4')에 위치되는 디스크개폐축(6)부분은 디스크개폐축(6)보다 직경이 작은 경사축(6')으로 형성하여 경사축(6')이 삽입되는 반원경사홈(11A)과 돌기(11B)를 형성한 한 쌍의 축홀더(11)(11')를 축받이(4')에 삽입하고 고정커버(12)의 구멍(12A)을 돌기(11B)에 끼워 볼트(13)로 고정하고 밸브몸체(1)에 고정한 베이스플레이트(14)에는 서로 대향되게 한쌍의 안내레일(14A)과 제어돌기(14B)및 경사상으로 슬라이더삽입홈(140)을 형성하고 디스크개폐축(6)의 사각부(6A)에는 긴슬라이더(15A)와 짧은슬라이더(15B)를 형성한 회전판(15)의 사각구멍(150)을 끼우는 한편 디스크개폐축(6)의 나사부(6B)에는 슬리브(16)를 나사맞춤하고 상기의 슬리브(16)에는 슬라이더끼움홈(701)과 걸림돌기(7A)를 형성한 웜휠(7)을 끼워 사각키(17)로 고정하고 외부로 빠지지 못하도록 록너트(18)로 고정하여 회전판(15)은 90˚로 정역회전시키고 웜휠(7)은 270˚로 정역회전시키는 것에 의하여 디스크(4)를 수평이동 및 회전시켜 개폐시킬 수 있도록 한 것을 특징으로 하는 메탈시트 버터플라이 밸브이다.The conventional metal seat butterfly valve is to move the disk slightly horizontally when opening the disk in close contact with the body seat of the valve body so that the disk seat of the disk away from the metal body seat to rotate the disk to open The metal seat butterfly valve is designed to reduce the frictional wear of the disc seat and the body seat to maintain a long service life and to improve the leakage blocking efficiency by making a strong contact with the valve seat. Referring to Figure 4 shown in more detail, in the conduit (3) of the valve body (1) fixing the metal body seat (2) of the disk (4) fixing the disk seat 5 to the disk opening and closing shaft (6) The worm wheel 7 is fixed to the disc opening / closing shaft 6 and engaged with the worm 9 having the handle 10 attached to the side of the casing 8 to open and close the disc 4. In the upper and lower portions of the disk 4, a shaft-shaped bearing 4 'having a shaft hole 401 is formed, and the disk opening / closing shaft 6 is inserted into the shaft 4 and is positioned on the bearing 4'. The disc opening and closing shaft 6 is formed of an inclined shaft 6 'having a smaller diameter than the disc opening and closing shaft 6 to form a semicircular inclined groove 11A and a projection 11B into which the inclined shaft 6' is inserted. Insert a pair of shaft holders 11 and 11 'into the bearing 4', insert the holes 12A of the fixing cover 12 into the protrusions 11B, and fix them with the bolts 13, and the valve body 1 On the base plate 14 fixed to the upper surface, a pair of guide rails 14A, a control protrusion 14B, and a slider insertion groove 140 are formed obliquely to face each other, and the square plate 6A of the disc opening / closing shaft 6 is formed on the base plate 14. While fitting the square hole 150 of the rotating plate 15 in which the long slider 15A and the short slider 15B were formed, the sleeve 16 was screwed into the threaded part 6B of the disc opening and closing shaft 6, The rib 16 is fitted with a slider fitting groove 701 and a worm wheel 7 formed with a locking protrusion 7A, fixed with a square key 17, and fixed with a lock nut 18 so as not to fall out to the rotating plate 15. Is a metal seat butterfly valve, characterized in that the forward and reverse rotation to 90 ° and the worm wheel (7) to be opened and closed by horizontally moving and rotating the disk (4) by forward and reverse rotation to 270 °.

그런데, 상기 종래의 메탈시트 버터플라이 밸브는 베이스플레이트(14)의 슬라이더삽입홈(140)과 회전판(15)과 웜휠의 회전판 접촉면의 축척된 가공오차로 인해 슬라이더삽입홈에 삽입된 회전판의 상부면과 웜휠의 회전판 접촉면 사이에 간격이 발생하며, 또한 계속된 작동에 따른 마모로도 간격이 발생하는 데, 이 간격으로 인해 슬라이더삽입홈에 삽입된 회전판이 웜휠의 회전판 접촉면에 닿을 때 까지 슬라이더삽입홈의 경사면을 따라 이동가능하게되고, 이 회전판의 이동으로 회전판 (15)의 사각구멍(150)에 사각부(6A)가 축끼움된 디스크개폐축(6)의 회전운동이 발생하게 되고, 이로 인하여 디스크가 보디시트에서 떨어질 때 디스크가 약간 회전한 다음 수평이동하게 되어, 디스크시트와 보디시트의 편마모가 발생하고, 밸브를 조금만 열고 닫을 때 세팅점이 틀려져 누수가 발생하는 문제가 있었다.However, the conventional metal seat butterfly valve has an upper surface of the rotary plate inserted into the slider insertion groove due to the accumulated processing error of the slider insertion groove 140 of the base plate 14 and the contact surface of the rotary plate of the rotary plate 15 and the worm wheel. And gap between the contact surface of the worm wheel and the rotary plate contact surface, and also with the wear caused by the continuous operation, which causes the slider insertion groove until the rotary plate inserted into the slider insertion groove contacts the contact surface of the worm wheel. It is movable along the inclined surface of the, and the movement of the rotating plate generates a rotational movement of the disk opening and closing shaft 6 in which the square portion 6A is pinched in the square hole 150 of the rotating plate 15, thereby When the disc falls off of the body seat, the disc rotates slightly and then moves horizontally, causing partial wear of the disc seat and body seat, and setting points when opening and closing the valve slightly. There was a problem that the wrong leak occurs.
