본 고안은 물, 유류, 가스, 공기등과 같은 각종유체가 흐르는 관로의 일정구간에 유체를 차단하는 볼 밸브의 몸통시이트링을 외부에서 조절가능한 볼 밸브에 관한것으로서, 특히 밸브몸통(1)의 좌우 양측면에 연결되는 플랜지어뎁터(2)(2')의 내주면에 단면이 사다리꼴 형상의 몸통시이트링 홈(3)(3')을 형성하며 홈(3)(3')내에 내장된 특수형상()의 탄성체 합성고무 또는 금속제인 몸통시이트링(4)(4')을 고정하는 다수로 분할, 일체로 조립된 단면이 특수한 삼각형 형상()의 환상의 시이트고정링(5)(5')을 밸브몸통외부 즉,플랜지어댑터(2)(2')외부에 장착된 테이퍼 쐐기구조의 다수의 조절볼트를 조정하여 밸브가 폐쇄시 폐쇄된 밸브 볼 양방향으로 작용하는 유체압력을 차단시키는 볼 밸브에 관한 것이다.The present invention relates to a ball valve that can externally control the body seat ring of the ball valve for blocking the fluid in a certain section of the pipeline through which various fluids, such as water, oil, gas, air, etc., in particular of the valve body (1) Special shapes embedded in the grooves 3, 3 'are formed on the inner circumferential surface of the flange adapters 2, 2' which are connected to both left and right sides and have a trapezoid-shaped body seat ring groove 3, 3 '. Is a triangular shape with a specially divided cross-section that is assembled into a number of parts to fix the body sheet ring (4) (4 ') made of elastic synthetic rubber or metal The annular sheet retaining ring (5) (5 ') is adjusted outside of the valve body, that is, by adjusting a plurality of adjustment bolts of tapered wedge structure mounted outside the flange adapter (2) (2'). A valve ball relates to a ball valve that blocks fluid pressure acting in both directions.

종래에도 볼 밸브가 제안 사용되어 왔으나, 종래의 볼 밸브는 완전한 구형상의 플러그(볼)와 탄성체 합성고무, 테프론의 밸브몸통시이트로서 수밀이 이루어지며, 또한 완전한 구형상의 플러그, 즉 볼의 가공이 정확하지 않을 뿐더러 또한 여기에 대응하여 수밀을 유지하는 밸브몸통시이트링의 가공이 정밀하지 못하여, 수밀이 완벽하지 못 할 뿐만 아니라, 밸브의 개폐시 밸브 볼, 즉 플러그가 개폐 회전될때에 까지, 다시말하면 플러그의 1/4회전까지,완전열림상태에서 완전닫힘상태까지,플러그와 밸브본체의 양쪽의 밸브몸통시이트링이 계속 접촉하면서 회전하므로, 개폐조작력이 크게 소요될 뿐 아니라, 대구경의 플러그의 가공이 불가능하여, 대구경의 볼 밸브생산은 불가능하며, 현재의 유체수송의 대형화 추세에 대응하지 못하는 등 어려운 실정입니다.Although ball valves have been proposed and used in the past, conventional ball valves are watertight as a valve body sheet of a full spherical plug (ball), an elastomer synthetic rubber, and Teflon, and a complete spherical plug, i.e., a ball, is precisely processed. In addition, the processing of the valve body seat ring for maintaining the watertightness is not precise, and the watertightness is not perfect, and the valve ball, i.e., the plug, is opened and closed when the valve is opened or closed. Up to 1/4 turn of the plug, from fully open to fully closed, rotates while the plug and valve body seat rings on both sides of the valve body keep in contact with each other, which not only requires a large opening and closing force but also makes machining of a large diameter plug impossible. It is impossible to produce large-diameter ball valves, and it is difficult to respond to the current trend of increasing the size of fluid transportation. The.

아울러, 밸브가 송수관로등에 설치되어 누수가 발생시에는 밸브 몸통시이트링 및 볼(플러그)시이트링 조정이 필요할 시에는 밸브를 관로에서 절단 또는 분리하여 조정하여야 할뿐 아니라, 유지관리가 용이하지 못할 뿐만 아니라, 경제적으로 상당한 손실이 발생하였다.In addition, when the valve is installed in the water supply line and the leakage occurs, when the valve body seat ring and the ball (plug) seat ring need to be adjusted, the valve must be cut or separated from the pipe line, and the maintenance is not easy. As a result, significant economic losses have occurred.

본고안의 목적은, 밸브 몸통의 좌우 양측면에 연결되는 플랜지어댑터의 내주면에 단면이 사다리꼴 형상의 몸통시이트링홈(3)(3')을 형성하며, 홈(3)(3')내에 내장된 특수형상()의 탄성체 합성고무 또는 금속제인 몸통시이트링(4)(4' )을 고정하는 다수로 분할, 일체로 조립된 단면이 특수한 삼각형형상()의 환상의 시이트 고정링(5)(5')을 밸브몸통 외부 즉 플랜지어댑터(2)(2')외부에 장착된 테이퍼 쐐기구조의 다수의 조절볼트를 조절하여, 밸브가 폐쇄시, 폐쇄된 밸브, 볼 양방향으로 작용하는 유체압력을 차단시는 볼 밸브에 관련한 것으로, 제작원가를 절감하고, 효율성을 높이며 유지관리가 편리하고 기존 볼 밸브보다 개폐조작력도 적게 소모된다.The purpose of this article is to form a trapezoidal body seat ring groove (3) (3 ') in cross section on the inner circumferential surface of the flange adapter which is connected to the left and right sides of the valve body and has a special shape embedded in the groove (3) (3'). ( Is a triangular shape with a specially divided cross-section that is assembled into a plurality of parts to fix the body sheet ring (4) (4 ') made of elastic synthetic rubber or metal Of the annular sheet retaining ring (5) (5 ') is adjusted outside of the valve body, i.e., the tapered wedge structure of a plurality of adjustment bolts mounted outside the flange adapter (2) (2'). Valve and ball are related to the ball valve to shut off the fluid pressure acting in both directions, reducing manufacturing cost, improving efficiency, convenient maintenance, and less opening and closing operation than conventional ball valve.

이하 본고안의 바람직한 실시예를 첨부한 도면에 의거 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

유체의 흐름을 차단하기 위해 볼 밸브를 폐쇄하고져 회전축(9)을 회전시켜 볼(플러그)(8)을 닫아 주면, 회전축(9)을 중심으로 좌우대칭으로 위치한 볼(플러그)시이트링(10)(10')이 특수형상()의 밸브 몸통시이트링(4)(4')의 정점에 서서히 압접되어 완전히 닫혔을 경우, 유체의 흐름을 정확히 차단하여 준다. 이때 양쪽의 볼(플러그)시이트링(10)(10')과 특수형상()의 밸브 몸통시이트링(4)(4')의 압착력을 균등하게 작용하도록 밸브몸통(1)의 좌우양측면에연결되는 양 플랜지어댑터(2)(2')의 각각의 내주면에 형성된 몸통시이트링홈(3)(3')내에 장착된 각 시이트고정링(5)(5')의 테이퍼구조의 쐐기형상의 경사접촉면(6')과 여기에 대향하는 플랜지어댑터(2)(2')의 홈(3)(3')외주부에 장착된 다수의 조절볼트(7)의 쐐기형상(4)의 경사접촉면(6')이 밸브몸통(1)의 중심에 대한 수직방향으로 미세이동이 가능하므로서, 특수형상()의 밸브몸통시이트링(4)(4')과 볼(플러그)시이트링(10)(10')의 균일한 압착력으로 좌,우 양쪽시이트링 원주방향으로 완벽하게 지수가 이루어지며, 압착정도도 조절볼트(7)의 나사부 죄임상태를 조정하므로서 용이하게 조정가능하며, 균일한 압착력으로, 밸브 개폐시 적은힘이 소요되므로, 원활한 작동이 이루어지며, 모터전동구동 등 외부동력 사용시에도 적은 동력이 소요되며, 밸브의 구조상 종래의 볼 밸브와는 달리, 밸브개폐시에 양쪽 몸통시이트링(4)(4')과 볼(플러그)시이트링(10)(10')은 개,폐시에만 양쪽의 각각 시이트링 이 압접하는 구조로서, 즉 밸브를 여는 상태에서는 볼(플러그)시이트링(10)(10')이 몸통시이트링(4)(4' )을 일단 벗어나는 지점부터는 일정기간 동안은 몸통시이트링(4)(4')과 간섭이 전혀없는 상태로 회전하게되며, 또한 역방향 회전시 즉 밸브를 닫는 경우에도 서로 각 시이트링이 전혀 간섭이 없는 상태에서 마지막 닫히는 순간에만 볼(플러그)시이트링(10)(10')이 몸통시이트링(4)(4')에 압착되므로서 수밀이 이루어지는 구조인 관계로 밸브 개폐시 종래의 볼 밸브보다 상당히 적은 힘으로 개폐가 이루어진다. 또한, 장시간 사용한 후 시이트링 부위의 마모등으로 누수가 발생할 시에는 밸브가 설치된 기존 밸브를 관로에서 분해하지 않고, 관로외부 즉 밸브몸통 외부 즉 플랜지어댑터(2)(2')의 외부에 착설된 다수의 조절볼트(7)의 나사부를 조정하므로서 쉽게 조정할수 있다.When the ball valve is closed to block the flow of the fluid, the rotation shaft 9 is rotated to close the ball (plug) 8, and the ball (plug) seat ring 10 is positioned symmetrically about the rotation shaft 9. (10 ') is a special shape ( When the valve body is slowly closed by being pressed against the apex of the valve body seat ring (4) (4 '), the flow of fluid is shut off accurately. At this time, both ball (plug) seat rings (10, 10 ') and special shapes ( Body seat ring grooves formed on the respective inner circumferential surfaces of the two flange adapters (2) and (2 ') connected to the left and right sides of the valve body (1) so as to equally apply the pressing force of the valve body seat ring (4) (4'). (3) Wedge-shaped inclined contact surface 6 'of the tapered structure of each seat fixing ring 5, 5' mounted in (3 ') and groove of flange adapter 2, 2' opposite thereto (3) Since the inclined contact surface 6 'of the wedge shape 4 of the plurality of adjustment bolts 7 mounted on the outer periphery of the 3' can be moved in the vertical direction with respect to the center of the valve body 1, Special shape The valve body seat ring (4) (4 ') and the ball (plug) seat ring (10) (10') are perfectly pressed in the circumferential direction of both the left and right seat ring circumferentially. It can be easily adjusted by adjusting the tightening state of the screw part of the adjusting bolt (7), and because of the uniform pressing force, less power is required when opening and closing the valve, so smooth operation is achieved, and less power is used even when using external power such as motor driving. Unlike conventional ball valves, both body seat rings (4) and (4) and ball (plug) seat rings (10) and (10 ') are both open and closed only when the valve is opened. Each of the seat rings is press-contacted, that is, the body seat for a certain period from the point where the ball (plug) seat ring (10) (10 ') leaves the body seat ring (4) (4') once the valve is opened. It will rotate without any interference with the ring (4) (4 '), and also in the reverse rotation Even when the valve is closed, the ball (plug) seat ring 10, 10 'is pressed against the body seat ring 4, 4' only at the moment of closing the seat ring without interference from each other. Due to the structure, the opening and closing of the valve is performed with a considerably less force than the conventional ball valve. In addition, when leakage occurs due to abrasion of the seat ring after using for a long time, the existing valve installed valve is not disassembled in the pipeline, but installed outside the pipeline, that is, outside the valve body, or outside the flange adapter 2, 2 '. It can be easily adjusted by adjusting the thread of the plurality of adjustment bolt (7).
