Description

디스크 가압형 버터플라이 밸브Disc Pressurized Butterfly Valve

본 발명은 밸브폐쇄시에 밸브본체에 축설된 디스크를 캠에 의한 수평운동으로 밸브시이트에 긴밀히 압착시켜 완벽한 수밀유지로서 누수를 방지할 수 있도록 안출한 디스크 가압형 버터플라이 밸브에 관한 것이다.The present invention relates to a disk pressurized butterfly valve which is designed so that the disk, which is built up in the valve body, is tightly compressed onto the valve seat by a cam by horizontal movement when the valve is closed.

통상의 버터플라이 밸브는 원통상의 밸브본체의 내주면에 금속재의 밸브시이트를 고정하고 회전축의 회전되는 원판상의 디스크의 외주면에 고무재질의 시이트링을 환착하여 디스크를 회전시키므로서 송배수 관로를 개폐하게 되어 있다.Conventional butterfly valves open and close the water supply and drainage pipeline by fixing the valve seat made of metal on the inner circumferential surface of the cylindrical valve body and returning the rubber sheet ring to the outer circumferential surface of the disk on the rotating disk. It is.

그러나, 종래의 버터플라이 밸브는 밸브폐쇄시에 디스크의 외주면이 밸브시이트에 접촉되는 접촉력에 의해 누수를 차단하게 되어 있으므로 잦은 개폐로 인해 시이트링이 마모되면 누수가 발생되고 이러한 누수현상은 수압이 높을수록 더욱 많이 발생되며 또한 디스크가 중심의 회전축에 의해서만 지지되도록 되어 있으므로 역수압에 심하게 요동되어 수밀성이 저하되었을 뿐 아니라, 특히 고무재의 밸브이트는 내산성과 내약품성이 불량하여 유류나 화공약품의 수송에는 부적합하였으며 금속재의 밸브시이트는 고도기술에 의한 정밀성이 요구되므로 제작이 용이하지 않는 등의 폐단이 있었다.However, in the conventional butterfly valve, when the valve is closed, the leak is blocked by the contact force of the disc's outer circumferential surface contacting the valve sheet. As the disk is supported only by the rotational axis of the center, it is severely fluctuated by reverse water pressure, and the watertightness is lowered. The valve seat of the metal has been closed because it is not easy to manufacture because it requires high precision by high technology.

따라서, 이러한 폐단을 해소하기 위한 밸브본체의 양측에 유압실린더를 설치하여 폐쇄시에 디스크를 유압에 의해 밀어 밸브시이트와 밀착되도록 한 것이 나온 바 있으나 이는 유압실린더를 설치하기 위한 부수적인 장치, 즉 유압펌프, 유압라인 등이 필요하여 구조가 복잡하고 제작원가가 고가인 등 여러가지의 폐단이 있었다.Therefore, the hydraulic cylinders are installed on both sides of the valve body for eliminating this closed end, so that the disk is pushed by the hydraulic pressure to close the valve seat when closing, but this is an additional device for installing the hydraulic cylinder, that is, the hydraulic pressure. Due to the need for pumps and hydraulic lines, there are various closures such as complicated structure and high production cost.

본 발명은 이와 같은 점을 감안하여 디스크를 회전시키는 회전축을 이중으로 구성하여 외측은 디스크를 90°각도로 회전시키고 내측은 회전운동을 캠에 의해 직선운동으로 변환시켜 디스크를 전, 후진시키므로서 디스크를 밸브시이트에 강하게 접촉시켜 누수를 완전히 차단한 것으로 이를 첨부도면에 의거 상술하면 다음과 같다.In view of the above, the present invention has a dual rotating shaft for rotating the disk, the outer side of which rotates the disk at an angle of 90 °, and the inner side of the disk by converting the rotational motion into a linear motion by the cam, thereby moving the disk forward and backward. Is to completely contact with the valve seat to completely prevent the leakage of water according to the accompanying drawings as follows.

원통형 밸브본체(1)의 관로(2)를 원판형 디스크(3)로서 개폐자재하는 통상의 버터플라이 밸브에 있어서 디스크(3)의 일면에 단면 형상의 보스(4)를 상하로 이격되게 고정하여 밸브본체(1)의 직경보다 긴 디스크 압착축(5)을 상단이 밸브본체(1)의 프랜지(6) 상부로 돌출되게 보스(4)의 중심공(4')으로 삽입하되 내측에 축착시킨 편심캡(7)(7')을 보스(4)의 내측 안내홈(8)에 재착시키고 밸브본체(1)의 내부에 위치한 디스크 압착축(5)의 상,하부 외주에는 디스크 개폐축(9)을 중첩 관삽하여 내측단부의 사각판(9')을 보스(4)의 외측 안내홈(8')에 유격(S) 있게 각각 끼워넣되 상부의 디스크 개폐축(9) 상단을 프랜지(6)의 상부로 돌출시켜 그 단부에 스플라인(10)를 형성하는 한편, 프랜지(6) 상부의 디스크 압착축(5)에 삽지홈(11)과 걸림돌기(12)를 회전방향의 순서대로 대향연설한 웜휠(13)을 축착하여 원통형 케이싱(14)의 측부에 핸들(15)을 부착시킨 웜(16)과 치합시키고 디스크 개폐축(9)의 스플라인(10)에는 중심기어공(17)과 좌우평행 경사면(18)을 가진 슬라이더(19)(19')를 양측에 돌설시킨 회전판(20)을 치합시켜 슬라이더(19)(19')가 웜휠(13)의 삽지홈(11)에 끼워져 프랜지(6) 상면의 안내레일(21)을 따라 회전되게 하되, 안내레일(21)에 마주보게 상향돌설시킨 낙하유도돌기(22)(22')에 의거 180℃를 정역회전되게 하고 닫히는 방향의 낙하유도돌기(22) 후축에 연하여 안내레일(21)에 슬라이더 삽입홈(23)(23')을 요설하여 웜휠(13)의 닫히는 방향회전시 회전판(20)의 슬라이더(19)(19')가 낙하유도돌기(22)(22')의 경사면(24)에 의거 슬라이더 삽입홈(23)(23')에 삽입되므로서 웜휠(13)과 분리되어 웜휠(13)만이 회전되게 하고, 또한 웜휠(13)의 열리는 방향회전시 걸림돌기(12)가 슬라이더(19)(19')를 이끌고 슬라이더 삽입홈(23)(23')으로 부터 빼내어 삽지홈(11) 끼워지게 하므로서 웜휠(13)과 결합되어 동시회전되게 한 구조이다.In a conventional butterfly valve which opens and closes the conduit 2 of the cylindrical valve body 1 as a disc-shaped disc 3, the cross section is formed on one surface of the disc 3. The boss 4 of the shape is fixed up and down spaced apart so that the disk pressing shaft 5 longer than the diameter of the valve body 1 so that the upper end protrudes above the flange 6 of the valve body 1 of the boss 4. Insert the eccentric cap (7) (7 ') is inserted into the center hole (4') and the inner side is compressed to the inner guide groove (8) of the boss (4) and the disk pressing shaft located inside the valve body ( In the upper and lower outer peripheries of 5), the disk opening and closing shafts 9 are overlapped and inserted into the square plates 9 'of the inner end to each other with a clearance S in the outer guide grooves 8' of the boss 4, respectively. The upper end of the disk opening and closing shaft (9) of the flange (6) to form a spline (10) at its end, while the insertion groove (11) and the locking block (11) on the disk pressing shaft (5) of the upper flange (6) The worm wheel 13, which has the machine 12 opposed to the other in the order of rotational direction, is fitted and engaged with the worm 16 having the handle 15 attached to the side of the cylindrical casing 14, and the spline of the disc opening / closing shaft 9 10) to Is a combination of the rotary plate 20 protruding on both sides of the slider 19, 19 'having the center gear hole 17 and the parallel parallel inclined surface 18, so that the sliders 19, 19' of the worm wheel 13 Inserted into the insertion groove 11 to be rotated along the guide rail 21 of the upper surface of the flange 6, 180 ° C based on the drop induction protrusion 22 (22 ') raised upward facing the guide rail 21. The slider insertion grooves 23 and 23 'are provided on the guide rails 21 so as to be connected to the rear axle of the falling induction protrusion 22 in the forward and closing directions so that the rotation of the worm wheel 13 in the closing direction of the worm wheel 13 is performed. The sliders 19 and 19 'are inserted into the slider insertion grooves 23 and 23' based on the inclined surfaces 24 of the drop-inducing protrusions 22 and 22 ', thereby being separated from the worm wheels 13 and the worm wheels 13 Only rotates, and the engaging protrusion 12 pulls the sliders 19 and 19 'out of the slider insertion grooves 23 and 23' when the worm wheel 13 is rotated in the open direction. Worm wheel (13) It is a co-rotating structure to be coupled.

도면중 미설명부호 25 은 보스(4)의 덮판이고, 26은 케이싱(14)의 상판이며, 27은 웜휠(13) 대용으로 사용되는 원판체이다.In the figure, reference numeral 25 denotes a cover plate of the boss 4, 26 a top plate of the casing 14, and 27 a disc body used as a substitute for the worm wheel 13.

이와 같이 된 본 발명은 원판형 디스크(3)의 일면에 이격되게 고정시킨 보스(4)의 중심공(4')으로 관통되는 디스크 압착축(5)을 밸브본체(1)에 수직으로 삽입하여 그 내측에 축착시킨 편심캠(7)(7')을 보스(4)의 내측 안내홈(8)에 재착시키고, 디스크 압착축(5)의 상,하부 외주에는 디스크 개폐축(9)을 중첩되게 관삽하여 내측 단부의 사각판(9')을 보스(4)의 외측 안내홈(8')에 유격(S) 있게 끼워넣은 것이므로 바깥축인 디스크 개폐축(9)을 회전시키면 보스(4)의 중심공(4')을 통해 외측 안내홈(8')에 끼워진 내측 단부의 사각판(9')이 보스(4)를 회전시킴에 따라 보스(4)가 고정된 디스크(3)가 강제 회전되어 관로(2)를 개폐하게 되고, 또한 디스크 개폐축(9)의 내부에 중첩 관삽된 디스크 압착축(5)을 회전시키면 보스(4)의 중심공(4')속에서 정위치 회전을 하게 되는데 디스크 압착축(5)의 내측에는 편심캠(7)(7')이 일체로 축착되어 보스(4)의 내측 안내홈(8)에 제착되어 있으므로, 디스크 압착축(5)이 제위치에서 회전되면 이에 축착된 편심캠(7)(7')의 편심회전으로 보스(4)를 디스크 개폐축(9)의 사각판(9')이 외측 안내홈(8')에 끼워져 형성된 유격(S)만큼 수평 이동시키게 됨에 따라 이와 일체로 고정된 디스크(3)가 관로(2)의 축선방향으로 직선 이동하여 밸브시이트에 보다 긴밀히 압착되어진다.According to the present invention, the disk compression shaft 5 penetrated into the center hole 4 'of the boss 4 fixedly spaced on one surface of the disk-shaped disk 3 is inserted into the valve body 1 vertically. The eccentric cams 7 and 7 'condensed on the inner side thereof are reattached to the inner guide grooves 8 of the bosses 4, and the disc opening and closing shafts 9 are superimposed on the upper and lower outer peripheries of the disc pressing shaft 5. Since the square plate 9 'of the inner end is inserted into the outside guide groove 8' of the boss 4 so as to have a clearance S, the disk opening shaft 9, which is the outer shaft, is rotated so that the boss 4 The disc 3 on which the boss 4 is fixed is forced as the square plate 9 'of the inner end, which is fitted into the outer guide groove 8' through the center hole 4 ', rotates the boss 4. Rotated to open and close the conduit (2), and also by rotating the disk compression shaft (5) inserted in the inside of the disc opening and closing shaft (9) is rotated in place in the center hole (4 ') of the boss (4) I'm going to do disk Since the eccentric cams 7 and 7 'are integrally compressed on the inner side of the pressing shaft 5 and fixed to the inner guide groove 8 of the boss 4, when the disk pressing shaft 5 is rotated in place, As a result of the eccentric rotation of the eccentric cams 7 and 7 ′, the boss 4 is formed by the clearance S formed by fitting the square plate 9 ′ of the disc opening and closing shaft 9 into the outer guide groove 8 ′. As it moves horizontally, the disk 3 fixed integrally therewith moves linearly in the axial direction of the conduit 2 and is pressed more tightly to the valve seat.

따라서, 본 발명을 실시함에 있어서는 핸들(15)을 돌려 웜(16)을 회전시키면 이와 합치된 웜휠(13)이 회전하여 디스크 압착축(5)을 회전시키게 되는데 웜휠(13)에는 저부의 삽지홈(11)에 디스크 개폐축(9) 상단의 스플라인(10)에 치합시킨 회전판(20)의 양측 슬라이더(19)(19')가 삽입되어 있으므로 웜휠(13)의 회전시 회전판(20)도 같이 회전하므로서 디스크 개폐축(9)과 디스크 압착축(5)이 동시에 회전하게 되는데, 특히 이때에는 디스크 압착축(5)이 편심캡(7)(7')이 편심회전하여도 디스크 개폐축(9)이 동시에 회전하여 디스크(3)가 회전되므로 편심회전력이 작용하지 않게 된다.Accordingly, in the practice of the present invention, when the worm 16 is rotated by turning the handle 15, the worm wheel 13 coincides with the worm wheel 13 to rotate the disk compression shaft 5. The worm wheel 13 has an insertion groove at the bottom of the worm wheel 13. Since the sliders 19 and 19 'on both sides of the rotating plate 20 engaged with the spline 10 at the upper end of the disc opening / closing shaft 9 are inserted into (11), the rotating plate 20 at the time of rotation of the worm wheel 13 is also the same. By rotating the disk opening and closing shaft (9) and the disk pressing shaft (5) is rotated at the same time, in particular at this time, even if the disk pressing shaft (5) eccentric cap (7) (7 ') rotates the disk opening and closing shaft (9) ) Rotates at the same time so that the disk 3 is rotated, the eccentric rotational power does not work.

따라서, 이와 같이 디스크 개폐축(9)과 디스크 압착축(5)이 동시에 회전하게 되면 디스크 개폐축(9)과 보스(4)(4')를 매개로 연결된 디스크(3)가 서서히 회전하여 관로(2)를 개폐하게 되는데 디스크(3)가 완전 개방된 상태에서 관로(2)를 일부 개폐하고자 할 때에는 핸들(15)를 돌려 웜(16)과 웜휠(13)을 원하는 거리만큼 정역회전시키면 웜휠(13)의 삽지홈(11)에 슬라이더(19)가 끼워진 회전판(20)이 동시에 회전하여 디스크 개폐축(9)을 회전시키므로서 관로(2)를 일부 개폐하게 된다.Thus, when the disk opening and closing shaft 9 and the disk pressing shaft 5 rotates at the same time, the disk 3 connected through the disk opening and closing shaft 9 and the bosses 4 and 4 'is gradually rotated to provide a conduit. (2) to open and close the disk (3) to open and close part of the conduit (2) to rotate the handle 15 to rotate the worm 16 and the worm wheel 13 forward and backward by the desired distance worm wheel The rotary plate 20 in which the slider 19 is fitted in the insertion groove 11 of 13 is rotated at the same time to rotate the disk opening and closing shaft 9, thereby partially opening and closing the conduit 2.

이와 같이 관로(2)을 일부 개폐하거나 또는 완전히 개방시킬 때에는 디스크 개폐축(9)의 스플라인(10)에 치합된 회전판(20)의 슬라이더(19)가 웜휠(13)의 삽지홈(11)에 끼워진 상태에서 프랜지(6)의 안내레일(21) 상면을 따라 활주하여 동시에 회전하게 되므로서 디스크(3)를 개폐하게 되나, 관로(2)를 완전히 차단할 때에는 핸들(15)을 끝까지 회전시키면 전술한 바와 같이 웜휠(13)의 삽지홈(11)에 끼워진 회전판(20)의 슬라이더(19)가 프랜지(6)의 안내레일(21)의 상면을 활주하면서 웜휠(13)과 동시에 회전하여 이에 치합된 스플라인(10)을 매개로 디스크 개폐축(9)을 회전시키므로서 관로(2)를 차단하게 되고, 디스크(3)가 완전 회전되어 관로(2)가 차단되면 회전판(20)의 슬라이더(19)는 안내레일(21)의 상면에 대향돌설된 낙하유도돌기(22)에 걸리게 됨과 동시에 좌우평행 경사면(198)이 낙하유도돌기(22)의 경사면(24)을 따라 슬라이더 삽입홈(23)으로 슬라이딩되어 낙하되므로서, 슬라이더(19)가 웜휠(13)의 삽지홈(11)으로부터 이탈되어 회전판(20)은 더 이상 회전되지 않고 윔휠(13)만이 회전되므로 디스크 개폐축(9)은 관로(2)를 폐쇄한 상태에서 회전이 정지되는 반면 웜휠(13)에 축착된 디스크 압착축(5) 만이 회전되어 전술한 바와 같이 디스크 압착축(5)에 편심축착된 편심캠(7)의 편심캠(7)의 편심회전으로 보스(4)를 유격(S)만큼 축선방향으로 직선이동시키므로서 디스크(3)가 밸브디스크에 강하게 밀착되어 관로를 완전 차단하게 되는 것이다.In this way, when the pipeline 2 is partially opened or fully opened, the slider 19 of the rotating plate 20 engaged with the spline 10 of the disc opening / closing shaft 9 is inserted into the insertion groove 11 of the worm wheel 13. The disk 3 is opened and closed by sliding along the upper surface of the guide rail 21 of the flange 6 in the fitted state, but when the block 15 is completely blocked, the handle 15 is rotated to the end to the above-mentioned. As described above, the slider 19 of the rotating plate 20 fitted into the insertion groove 11 of the worm wheel 13 slides on the upper surface of the guide rail 21 of the flange 6 and rotates simultaneously with the worm wheel 13 to be engaged with it. When the disk opening and closing shaft 9 is rotated through the spline 10, the pipeline 2 is blocked. When the disk 3 is completely rotated and the pipeline 2 is blocked, the slider 19 of the rotating plate 20 is blocked. Is caught by the falling induction projection 22 protruding from the upper surface of the guide rail 21, and at the same time, As the slope 198 slides along the inclined surface 24 of the drop guide protrusion 22 to the slider insertion groove 23 and falls, the slider 19 is separated from the insertion groove 11 of the worm wheel 13 so as to rotate. Since the wheel 20 is no longer rotated and only the wheel wheel 13 is rotated, the disk opening / closing shaft 9 stops rotating while the conduit 2 is closed, while the disk pressing shaft 5 which is fixed to the worm wheel 13 is closed. Only the disk is rotated and the disk is moved by the eccentric rotation of the eccentric cam 7 of the eccentric cam 7, which is eccentrically fixed to the disk pressing shaft 5, so as to linearly move the boss 4 in the axial direction by the clearance S. (3) adheres tightly to the valve disc, completely blocking the pipeline.

이와 같이 디스크(3)가 완전차단한 상태에서 디스크(3)를 열 때에는 핸들(15)을 차단할 때와는 반대방향으로 회전시키게 되면 먼저 슬라이더 삽입홈(23)에 낙화되어 안치된 회전판(20) 보다 많이 회전되어 있던 웜휠(13)의 걸림돌기(12)가 회전판(20)의 슬라이더(19)에 접면될 때까지 웜휠(13) 단독으로 회전되어 디스크 압착축(5)을 약간 회전시키므로서 밸브시이트에 밀착되어 있던 디스크(3)를 뒤로 미세하게 후튀시키게 되고, 이어서 웜휠(13)이 계속 회전되어 걸림돌기(12)가 회전판(20)의 슬라이더(19)에 당접되면 걸림돌기(12)가 회전되는 힘으로 슬라이더 삽입홈(23)에 안치되어 있는 회전판(20)을 이끌고 나와 안내레일(21)의 상면에 재치시키게 됨과 동시에 삽지홈(11)에 삽입되어지므로서, 회전판(20)의 웜휠(13)과 동시에 회전되기 시작하여 디스크 압착축(5) 및 디스크 개폐축(9)을 동시회전시키게 되므로 전술한 바와 같은 작동으로 디스크(3)가 열리기 시작하고 회전판(20)은 슬라이더(19)가 낙하유도돌기(22)의 후단에 당접되면 디스크(3)는 완전히 열리게 되어 관로(2)의 개방을 완료하게 되는 것이다.As described above, when the disc 3 is opened in the state where the disc 3 is completely blocked, when the disc 15 is rotated in the opposite direction as when the handle 15 is blocked, the rotating plate 20 fallen and settled in the slider insertion groove 23 is first placed. The locking protrusion 12 of the worm wheel 13, which has been rotated more, is rotated by the worm wheel 13 alone until it is brought into contact with the slider 19 of the rotating plate 20, thereby slightly rotating the disk compression shaft 5, and thus the valve. The disk 3 adhered to the sheet is finely flipped backward, and then the worm wheel 13 is continuously rotated so that the locking protrusion 12 contacts the slider 19 of the rotating plate 20. The worm wheel of the rotating plate 20 is driven by the rotating plate 20 which is settled in the slider inserting groove 23 by the rotating force and is mounted on the upper surface of the guide rail 21 while being inserted into the inserting groove 11. The disc press shaft (5) and the de Since the disc opening and closing shaft 9 is rotated simultaneously, the disc 3 starts to open by the above-described operation, and the rotating plate 20 is the disc 3 when the slider 19 contacts the rear end of the drop-inducing protrusion 22. Is completely opened to complete the opening of the conduit (2).

그리고, 본 발명의 실시예로서 제 3 도와 같이 웜휠과 웜을 사용하지 않고 디스크 압착축(5)의 상단에 핸들(15)을 직접 연결하고 웜휠대신에 원판체(27)를 축착하게 되면 전술한 바와 같은 동일효과를 얻을 수 있으나 대형보다는 소형의 밸브에 적합하다.As an embodiment of the present invention, if the handle 15 is directly connected to the upper end of the disk pressing shaft 5 without using the worm wheel and the worm as shown in FIG. 3, the disc body 27 may be condensed instead of the worm wheel. The same effect can be obtained, but it is suitable for valves smaller than large ones.

이와 같이 본 발명은 디스크(3)를 완전히 닫은 상태에서 디스크 압착축(5)의 캠(7)(7')에 의한 직선운동으로 디스크(3)를 밸브시이트에 보다 강하게 압착시키므로서 누수를 완전히 차단하고 역수압 등에 의한 디스크의 요동을 방지하여 수밀성을 증가시키는 효과가 있으며, 특히 본발명의 밸브장치에 의하면 고무재 뿐 아니라 금속재의 밸브시이트를 모두 사용할 수 있으므로 유류나 화공약품을 수송하는 관로의 개폐에 적합하게 사용할 수 있으며, 또한 금속재의 밸브시이트를 종래와 같이 정밀가공하지 않아도 인위적으로 디스크를 강하게 밀착시킬 수 있어 가공비가 절감되는 등의 그 효과가 매우 지대한 우수한 발명이다.As described above, the present invention presses the disk 3 to the valve seat more strongly by linear movement by the cams 7 and 7 'of the disk pressing shaft 5 in the state where the disk 3 is completely closed, thereby completely leaking water. It is effective in blocking water and preventing the fluctuation of the disk due to back water pressure and increasing watertightness.In particular, the valve device of the present invention can use not only rubber but also metal valve seat, so that it can be used to transport oil or chemicals. It can be suitably used for opening and closing, and it is an excellent invention having a great effect such that the disk valve sheet made of metal can be artificially strongly adhered to it even without precision processing as in the prior art, thereby reducing the processing cost.
