본 고안은 고압의 액체 또는 기체의 흐름을 개폐시키는 버터플라이 밸브에 있어서, 특히, 본 고안 출원인에 의해 기등록된 등록 제27924호의 “내 고압력 버터플라이 밸브”를 이용 개량한 고안에 관한 것이다.The present invention relates to an improved design of a butterfly valve for opening and closing a high pressure liquid or gas flow, in particular, using the "my high pressure butterfly valve" of registration No. 27924 previously registered by the applicant of the present invention.

전기한 기등록고안은 종래의 편심회전축에 의한 버터플라이 밸브와 합리적이지 못한 패킹 장착상태, 고정시 정비가 곤란한 문제점등을 개선한바 있으나, 이는 그 디스크 회전축의 주면에 요홈을 형성하여 이에 맞는 “”형 패킹을 감입하고 그 패킹의 연결홈에 의대 디스크의 주연에 원형 패킹테를 일체로 연결하였던 것이어서, 비교적 그 수밀 구조가 복잡하여 제조원가가 상승되는 문제점이 있었으며 디스크와 당접되는 밸브시이트의 당접면이 직각으로 이루어져 있어 유체의 흐름에 영향을 많이 주었을 뿐 아니라, 특히 공업용수나 농업용수등의 송수관용으로 사용될때에는 그 밸브시이트의 당접면에 이물질이 축적되어 유체흐름이 차단시에 디스크가 밸브사이트와 완전 밀착되지 못하고 틈새가 발생하는 원이 되므로서 이에 의해 유체가 누수되는 결점이 있었다.The previous registration proposals have improved the conventional butterfly valve by the eccentric rotation shaft, the packing state that is not reasonable, and the difficulty of maintenance when fixing, but this is formed by forming a groove on the main surface of the disk rotation shaft. ”Indented type packing and integrally connected circular packing frame at the periphery of meditation disk to connecting groove of the packing have relatively high watertight structure, which increases the manufacturing cost and the contact surface of valve seat contacted with disk. This perpendicular angle not only affects the flow of the fluid, but especially when it is used for water pipes such as industrial water or agricultural water, foreign matter accumulates on the contact surface of the valve seat. There was a drawback in that the fluid leaked because it became a circle where gaps could not be brought into close contact with each other.

또한 일본공개 실용신안공보 소 57-190173호와 같은 편심회전축에 의한 버터플라이 밸브는 회전축에 대한 밀폐구성이 없고 밸브시이트가 회전축을 중심으로 일측으로 치우쳐 형성되고 그 패킹이 감착된 디스크의 밸브체 역시 한쪽면에만 형성되어 있기 때문에 그 상태에서의 디스크 회전이 불가능하므로 밸브가 개폐를 위해 회전축이 회전키 위해서는 회전축이 회전과는 별도로 디스크의 전후 유격이동이 필요한 번거로움이 있고 그 회전을 위하여 경사면을 완만하게 두어야 하고 유격이 필요하므로 패킹면과 밸브시트면의 밀착성이 떨어지게 되어 수밀성이 약한 결점이 있었다.In addition, the butterfly valve by the eccentric rotation shaft, such as JP-A 57-190173, does not have a closed configuration about the rotation shaft, and the valve body of the disk is formed with the valve seat biased to one side about the rotation shaft, and the packing body is also depressed. Because it is formed only on one side, it is impossible to rotate the disk in that state.Therefore, the rotation shaft is rotated to open and close the valve.The rotation shaft needs to move back and forth between the disks, and the slope is smooth for the rotation. Because of the need for clearance, the adhesion between the packing surface and the valve seat surface is inferior, resulting in weak watertightness.

본 고안은 버터플라이 밸브에 있어서 전기한 바와 같은 결점을 제거코저 고안한 것으로서, 본 고안의 요지를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been devised to eliminate the above-mentioned defects in the butterfly valve, and the subject matter of the present invention will be described in detail with reference to the accompanying drawings.

밸브 본체(1)의 내면에 밸브시이트(2)(2')를 돌출형성하고 그 중앙에 디스크(3)를, 상하의 원통지지체(4)(4')에 회전축(5)(5')을 삽입하여 축설하고, 밸브시이트(2)(2)의 당접면(2a)(2a')을 회전축(5)(5')을 중심으로 상하가 서로 반대방향을 향하고 있는 경사면으로 형성하고, 디스크(3)의 주연 역시 상하 사로 다른쪽면에 결합요턱(8)을 형성하여 전기 당접면(2a)(2a')과 동일한 경사면의 당접면을 갖는 패킹테(9)를 그 압착판(10)으로 고정시켜 서로 밀착 당접 되게한 통상의 버터플라이 밸브에 있어서, 상하 원통지지체(4)(4')의 당접면(4a)(4a')을 원추형상으로 하고 이에 동일형상의 당접면을 갖는 패킹(6)(6')을 당접시켜 T자형 덮개한(7)(7')으로 압착시킨 것이다.The valve seats 2 and 2 'are protruded on the inner surface of the valve body 1, and the disk 3 is positioned at the center thereof, and the rotary shafts 5 and 5' are attached to the upper and lower cylindrical supports 4 and 4 '. Inserted and laid out, the contact surfaces 2a and 2a 'of the valve seats 2 and 2 are formed on the inclined surfaces of which the upper and lower sides are opposed to each other about the rotary shafts 5 and 5', and the disk ( The periphery of 3) is also formed on the other side with the upper and lower yarns to fix the packing frame 9 having the contact surface of the same inclined surface as the electrical contact surface 2a, 2a 'with the pressing plate 10. In the conventional butterfly valve which is brought into close contact with each other, the contact surfaces 4a and 4a 'of the upper and lower cylindrical supports 4 and 4' are conical and have packings having the same contact surfaces. 6 ') is abutted and crimped with a T-shaped cover (7) (7').

미설명 부호 11.11'는 결합용 볼트, 12. 12'는 후랜지, 13.13'는 지지각이다.Reference numeral 11.11 'is the coupling bolt, 12. 12' is the flange, 13.13 'is the support angle.

이상과 같은 본 고안의 작용효과를 상세히 설명하면 다음과 같다.Referring to the effects of the present invention as described above in detail.

회전축(5)(5')이 디스크(3)의 중심부에 축착형성된 것이어서 그 좌우회전 운동시 좌우균형이 유지되어 전후 유격이동이 필요없이 그 개폐작동을 원활하게 할 수 있는 것인데, 디스크(3)의 좌우에 형성된 원통지지체(4)(4')의 당접면(4a)(4a')이 이에 맞닿아 있는 패킹(6)(6')의 당접면과 함께 원추형상으로 되어 있어 T자형 덮개판(7)(7')으로서 압착고정할 경우 패킹(6)(6')의 상하측 및 좌우로의 반작용에 의한 팽만성에 의해 구조가 단순하면서도 축 부위가 완전 수밀되어 유체가 회전축(5)(5')으로 누출됨이 없이 안전하게 사용할 수 있는 것이다.Rotating shaft (5) (5 ') is formed in the center of the disk (3) is concentrically formed so that the left and right balance during the left and right rotational movement can smoothly open and close the operation without the need to move back and forth, the disk (3) The contact surfaces 4a and 4a 'of the cylindrical supports 4 and 4' formed on the left and right sides of the cylindrical support are conical with the contact surfaces of the packings 6 and 6 'contacted thereto. (7) (7 ') When it is pressed and fixed, the swelling property by the reaction of the packing 6, 6' on the upper and lower sides and the left and right is simple and the watertight part is completely watertight, so that the fluid is rotated (5) ( 5 ') can be used safely without leaking.

또한 디스크(3) 주연부의 패킹테(9)가 당접밀착되어 유체의 흐름을 차단 또는 개통시키는 밸브시이트(2)(2')가 제 4 도의 도시와 같이 그 당접면(2a)(2a')이 종래와 같은 즉, 관체 전 내주벽에 걸쳐 일방향으로만 완만하게 형성되거나, 수직으로 돌출 형성되지 아니하고 상하 양측이 반대 방향을 향해 돌출면과 경사면으로 형성되어 있어 동일한 경사면을 패킹테(9)와의 단위 면적당 당접면적을 그 경사면과 저부평면의 양면에 걸쳐서 넓혀 수밀성을 증대 시킴과 동시에 공업용수나 농업용수등 유체의 흐름시에 그 유체중에 이물질이 섞여 있더라도 밸브시이트(2)가 경사면으로 형성되어 있어 유체중의 이물질이 걸리지 않고 그 경사면을 타고 넘어가게 되므로 이에 이물질이 축적될 염려가 없어 종래와 같이 이물질등으로 인한 당접면의 틈새등의 발생되지 않고 안전 밀착되므로서 완전한 수밀이 가능한 것이다.In addition, a valve seat 2 (2 ') which is in close contact with the packing frame 9 at the periphery of the disk 3 to block or open the flow of the fluid has its contact surfaces 2a and 2a' as shown in FIG. That is the same as that of the conventional, i.e., it is formed smoothly in only one direction over the inner circumferential wall before the pipe, or is not formed to protrude vertically, but the upper and lower sides are formed as the protruding surface and the inclined surface in the opposite direction, so that the same inclined surface with the packing frame 9 The contact area per unit area is extended across both the inclined and bottom planes to increase watertightness, and the valve seat 2 is formed as an inclined surface even if foreign matter is mixed in the fluid flow such as industrial water or agricultural water. There is no fear of foreign matters accumulating because the foreign substance does not get caught and goes over the inclined surface. Therefore, the gap of the contact surface caused by the foreign substance does not occur as before. Since safety stand close as possible to a perfect watertight.

디스크(3) 주연에 대한 패킹테(9)의 결합은 결합요턱(8)을 형성하여 이에 패킹테(9)를 밀착시킨후 중앙부가 돌출형성된 압착판(10)으로 압착고정한 것이어서 패킹(9)이 상하로 팽만성을 갖게 하여 밸브시사이트(2)와의 수밀성을 더욱 극대화 시킬수 있는 것이며 견고한 결착으로 사용중 분리되는 등의 고장의 염려가 없는 것이다.The coupling of the packing frame 9 to the circumference of the disk 3 forms a coupling yoke 8, which is in close contact with the packing frame 9, and then pressed and fixed to the compression plate 10 with the center portion protruding from the packing 9. This swelling up and down can maximize the watertightness with the valve seasite (2) and there is no fear of failure such as separation during use due to the solid binding.

이상과 같이 본 고안은 비교적 단순한 구조로서로 수밀성이 매우 높고 이물질이 침적될 염려가 없어 고장의 염려가 없는 내고압력 버터플라이 밸브를 저렴한 가격으로 제공되게한 효과가 있는 것이다.As described above, the present invention has a relatively simple structure, which has a high water tightness and there is no fear of foreign matters being deposited, thereby providing a high pressure butterfly valve with no fear of failure, at a low price.
