본 고안은 폐쇄관로의 일측에 위치하면서 유체의 흐름을 단속하는 볼밸브의 개폐장치에 관한 것으로서, 개폐장치의 구조를 개선하여 레버 조작상의 편리성 및 정확성을 기하고, 사용후에는 레버 스스로가 원위치 복귀되도록 하여 유체의 유실 방지와 사용의 편리성을 제공토록 함을 목적으로 안출 제공된 것이다.The present invention relates to an opening and closing device of a ball valve to control the flow of fluid while being located on one side of a closed pipe, and improves the structure of the opening and closing device to ensure convenience and accuracy in lever operation, and the lever itself is returned to its original position after use. It is provided for the purpose of returning the fluid to prevent the loss of fluid and provide convenience of use.
종래의 볼밸브 개폐장치를 보면, 도면 제3도에서와 같이 밸브몸체(1')에 삽입 설치된 회전구(2')의 상단 결합부(21')와 관통 결합될 레버(4')선단부의 4각구멍(6')이 측면과 수평방향으로 형성됨에 따라, 이를 결합시에는 밸브몸체(1)와의 수직위치에서의 오프상태로 위치하고, 수평위치로 회전시켰을때 온 동작되도록 설치하는 것이다.In the conventional ball valve opening and closing device, as shown in FIG. 3, the tip of the lever 4 'which is to be penetrated and coupled with the upper engaging portion 21' of the rotary hole 2 'inserted into the valve body 1' is shown. As the quadrilateral hole 6 'is formed in the horizontal direction with the side, when it is coupled, it is installed in the off state in the vertical position with the valve body 1, and is installed to be turned on when rotated to the horizontal position.
그런데, 상기 레버는 그 선단 양측의 돌출부(5')와 밸브몸체(1')의 스톱퍼(3')에 의해 약 90°범위내에서 일측으로만 선회동작 되도록 구성되어 있기 때문에, 상기와 같이 레버(4')가 밸브 몸체(1')와 수직으로 설치된 오프상태에서 온 상태로 전환시키고져 이를 손으로 잡고 돌려줄때에 밸브 사용에 익숙치 못하거나, 긴박하거나 조급한 상태에서는 종종 규정된 방향이 아닌 역방향쪽으로 순간적인 힘을 가했다가. 상기 돌출부와 걸림턱에 의해 돌아가지 않으므로 다시 반대방향(정상동작방향)으로 돌리게되는 시행착오적인 사례가 빈번히 발생하므로서, 사용자가 조작에 상당한 혼성을 빗게되고, 밸브에 무리가 가해져서 쉽게 손상되거나 수명이 단축되는 조작상의 문제점이 있었다.By the way, since the lever is configured to pivot only one side within the range of about 90 ° by the stopper 3 'of the valve body 1' and the protruding portion 5 'on both sides of the tip, the lever as described above. When (4 ') is turned on from the off state installed perpendicular to the valve body (1') and turned and held by the hand, it is often unfamiliar to the use of the valve, in a tight or impatient state, often not in the prescribed direction. Momentary force in the opposite direction. As the trial and error cases frequently turn back to the opposite direction (normal operation direction) because they are not rotated by the protrusions and the locking jaws, the user may comb a considerable amount of hybridity to the operation, and the valves may be excessively damaged or have a long service life. There was an operation problem that is shortened.
또한, 상기 밸브는 사용자가 일일이 레버를 정, 역방향으로 돌려서 개방과 폐쇄동작을 시켜야하므로 사용상의 불편은 물론이거니와, 한번 개방된 레버는 자동 복귀되지 않으므로 사용자의 망각에 의해 개방시킨 상태가 계속 유지되면 필요이상의 유체가 계속 배출 낭비되는 등의 사용상의 문제점도 있었다.In addition, the valve has to be opened and closed by the user to turn the lever in the forward and reverse directions one by one, so it is not inconvenient to use the valve, and once opened, the lever is not automatically returned. There were also problems in use, such as the continued waste of excess fluid.
따라서, 본 고안은 종래의 위와같은 문제점을 해결하기 위하여, 작동레버를 몸체의 상하 45°범위에서 회전개폐동작할수 있도록 사각 설치하였으며, 밸브 몸체와 레버 사이에 자동 복귀용 비틀림 스프링체를 설치하여 사용후에는 자동적으로 원위치로 복귀되면서 관로를 차단시킬수 있도록 한 것으로서, 이를 첨부된 도면을 따라 상세히 설명하면 다음과 같다.Therefore, in order to solve the above problems, the present invention has a rectangular installation to rotate the opening and closing operation of the operating lever in the upper and lower 45 ° range of the body, and installs a torsion spring body for automatic return between the valve body and the lever. After the automatic return to the original position to block the conduit, it will be described in detail according to the accompanying drawings as follows.
즉, 레버 결합부(21)를 구비한 개폐용 회전구(2) 및 스톱퍼(3)가 형성된 밸브몸체(1)와, 선단부 양측에 회전각도 제어용 돌출부(5) 및 상기 결합부(21)관통 결합용 4각 구멍이 형성된 레버(4)를 결합 설치함에 있어서, 도면 제1도, 제2도에서와 같이 레버(4)의 4각구멍(6)의 형성각도를 측면과 45°사각방향으로 신장되도록 관통 형성하여, 레버(4)가 밸브몸체(1)의 상부 45°사각위치에서 관로가 차단 오프되고, 후단부위를 아래로 눌러 하부 45°위치에 도달하였을때 관로가 최대로 개방되도록 하였다.That is, the valve body 1 having the opening / closing rotating tool 2 and the stopper 3 having the lever engaging portion 21 formed thereon, and the rotating angle control protrusion 5 and the engaging portion 21 passing through both ends thereof. In the installation of the lever 4 formed with the coupling quadrangular holes, as shown in FIGS. 1 and 2, the angle of formation of the quadrilateral holes 6 of the lever 4 is 45 degrees to the side and 45 degrees. Penetration was formed so that the lever 4 was blocked off at the upper 45 ° square position of the valve body 1, and when the rear end was pressed down to reach the lower 45 ° position, the pipeline was opened to the maximum. .
그리고, 상기 레버(4)와 밸브 몸체(1)사이에는 외력이 가해지지 않는 상태에서 레버(4)를 오프상태로 복귀시킬수 있는 탄성을 가지는 비틀림스프링체(7)가 설치되는데, 상기 스프링체(7)의 일측단부위는 레버(4)의 내측면 일측과, 또 다른 일측단은 절곡시켜 밸브 몸체(1)의 일측부위에 권회고정 설치하므로서, 레버(4)의 후단부위를 아래로 눌러 관로를 개방시키고 있다가, 가하던 힘을 제거하면 압축된 스프링체(7)의 응력에 의해 레버(4)가 자동적으로 오프상태로 원위치 되므로서 관로가 차단되는 것이다.In addition, a torsion spring body 7 having elasticity capable of returning the lever 4 to an off state is installed between the lever 4 and the valve body 1 without an external force applied thereto. 7) one side end portion of the inner side of the lever (4) and the other side end is bent and installed in one side portion of the valve body (1), while pressing the rear end portion of the lever (4) down the pipe line After opening, remove the applied force, the pipeline is blocked because the lever (4) is automatically returned to the off position by the stress of the compressed spring body (7).
이상과 같이 레버(4)가 밸브 몸체(1)와 45°의 사각형태로 설치됨에 따라, 밸브를 온시키고져 레버(4)를 돌리려고 하는 사람은 누구나가 인간 심리상 후단부를 자연스럽게 중력방향인 하방으로 눌러주는 관계로, 종래의 수직 설치구조에서 종종 발생하던 오동작과 밸브의 억지 조작에 따른 조기마모 및 파손을 완벽하게 방지하고, 작동상의 정확성과 제품의 수명을 연장시킬수 있는 효과와 함께, 레버(4)가 비틀림 스프링체(7)에 의해 자동 복귀되므로 사용자의 실수로 인한 불필요한 유체의 낭비를 완벽하게 방지함은 물론이고, 반자동식 조작에 따른 사용상의 편리성을 제고시킬수 있는 특출한 효과가 있는 것이다.As the lever 4 is installed in the rectangular shape of 45 ° with the valve body as described above, anyone who turns on the valve and tries to turn the lever 4 naturally has the rear end of the human psychological direction. With downward pressure, the lever can be completely prevented from the normal operation and failure of the valve and the early wear and tear caused by the forced operation of the valve, and the operation accuracy and the life of the product can be extended. (4) is automatically returned by the torsion spring body (7) to prevent the unnecessary waste of the fluid completely due to the user's mistake, as well as the special effect that can enhance the convenience of use according to the semi-automatic operation It is.
여기에서, 상기 레버(4)는 통상 외부압을 가해야 개방상태를 유지할수 있도록 구성되어4있으나, 일정 각도마다에 상기레버와 면접촉되는 톱니형 스톱퍼를 구비한 통상적인 개방상태 유지장치(도시하지 않음)를 상기 밸브 몸체의 상부 일측에 간단히 부설하면 레버(4)의 개방상태를 지속적으로 유지시킬 수도 있는 것이다.Here, the lever (4) is usually configured to maintain the open state only when an external pressure is applied, but a conventional open state maintaining device having a toothed stopper which is in surface contact with the lever at a predetermined angle (not shown) If not attached simply to the upper one side of the valve body may be to maintain the open state of the lever (4) continuously.
