As shown in FIG. 4, a lock 28 is provided to constitute the handle portion.

본 고안의 작용에 대하여 설명하면 아래와 같다Referring to the operation of the present invention as follows

먼저, 관련도면 도2에서는, 기존의 볼밸브[6] 손잡이를 고정하고 있는 고정 너트[10]와 와셔1[11]과 손잡이[9] 그리고, 와셔2[15]를 분리하여 순서대로 도시하였는데, 관련 도면 도3에서는 손잡이[9] 아래쪽에 있던, 와셔2[15]를 제거하는 대신에, 열림 블록[25]과 닫힘 블록[24]이 설치된 요철부[27]를 볼트[16]에 삽입하게 되는데, 요철부 전면에 형성된 절개부가 원형 바디[18]의 돌출부[19]에 일치하도록 삽입하면, 요철부[27]는 돌출부[19]에 의해 완전히 고정되게 되며, 그 다음에는 손 잡이[9]에 형성된 결합부1[12]을 볼트[16]에 삽입하면, 볼트의 하단부에 형성된 결합부2[17]와 서로 결합되게 된다First, in FIG. 2, the fixing nut [10], the washer 1 [11], the handle [9], and the washer 2 [15], which hold the handle of the conventional ball valve [6], are separately shown in order. In Fig. 3, instead of removing the washer 2 [15], which was under the handle [9], the concave-convex portion [27] provided with the opening block [25] and the closing block [24] is inserted into the bolt [16]. If the cutout formed on the front surface of the uneven portion is inserted to coincide with the protrusion [19] of the circular body [18], the uneven portion 27 is completely fixed by the protrusion [19] and then the handle [9]. ] Is inserted into the bolt 16, the coupling portion 1 [12] formed in the

그리고, 손잡이[9]의 윗부분을 고정하게 되는 와셔1[11]과 고정 너트[10]를 볼트[16]에 순서대로 삽입하여 고정 너트[10]를 완전히 고정하게 되면, 본 고안의 조립이 완성되는 것이다Then, when the washer 1 [11] and the fixing nut [10], which are to fix the upper part of the handle [9], are inserted into the bolt [16] in this order to completely fix the fixing nut [10], the assembly of the present invention is completed. Will be

또한, 손잡이[9]의 슬라이딩부[20]에는 이동 바디[22]가 삽입되어 있는데, 이동 바디[22]는 슬라이딩부의 크기보다 조금 더 크게 제작되어 있어서, 슬라이딩부의 약 60도 정도의 경사진 부분에서 위아래로 이동하기에 용이하도록 고안되었으며, 이동 바디[22]의 하부에 설치되어 있는 삽입부[23] 또한, 요철부에 설치되어 있는 열림 블록[25]와 닫힘 블록[24]의 크기보다 조금 더 크게 설계되었다In addition, a moving body 22 is inserted into the sliding portion 20 of the handle 9, and the moving body 22 is made slightly larger than the size of the sliding portion, so that the inclined portion of the sliding portion is about 60 degrees. It is designed to be easy to move up and down in the, and the insertion portion [23] which is installed in the lower portion of the moving body [22] is also slightly smaller than the size of the opening block [25] and closing block [24] installed in the uneven portion Was designed larger

따라서, 관계도면 도4에서 보는바와 같이, 슬라이딩부에 형성되어 있는 자물쇠 삽입구[21]에 자물쇠[28]을 결합하게 되면, 완전한 형태의 볼밸브 손잡이 고정 장치가 완성되는 것이다Therefore, as shown in FIG. 4, when the lock 28 is coupled to the lock insertion hole 21 formed in the sliding part, the ball valve knob fixing device of a complete form is completed.

기존의 산업 현장이나 실생활에서 많이 사용되고 있는 볼밸브[6]에 부착된 손잡이[9]를 취외한 후, 관련도면 도3에 도시한 바와 같이, 와셔2[15]를 제거하는 대신에, 요철부[27]를 삽입한 후, 경사진 슬라이딩부에 이동 바디[22]가 삽입된 볼밸브 손잡이를 결합하게 되면, 밸브가 수평으로 설치된 경우, 이동 바디[22]는 약 60도의 경사진 슬라이딩부[20] 아래쪽으로 내려와서 위치하게 되므로, 이동 바디의 하단부에 형성된 삽입부[23]는, 요철부[27]의 열림 블록[25]이나 닫힘 블록[24]과 만나서, 항상 결합된 상태를 유지하게 된다After removing the handle [9] attached to the ball valve [6], which is widely used in the existing industrial field or real life, as shown in FIG. 3, instead of removing the washer 2 [15], the uneven portion [27] and after inserting the ball valve handle into which the moving body [22] is inserted into the inclined sliding part, when the valve is installed horizontally, the moving body [22] is inclined sliding part of about 60 degrees [ 20] Since it is positioned downward, the insertion portion 23 formed at the lower end of the moving body meets the opening block 25 or the closing block 24 of the uneven portion 27 so that it is always kept in a coupled state. do

따라서, 볼밸브[6]의 개폐를 위하여 손잡이[9]를 회전하고자 할 때에는 이동 바디[22]를 슬라이딩부 상부쪽으로 밀어 올린 다음, 손잡이를 원하는 방향으로 회전시킨 후에, 이동 바디[22] 놓게 되면, 슬라이딩부의 상부쪽에 위치하고 있던 이동 바디가 경사면을 따라 자연스럽게 아래쪽으로 내려와서, 요철부[27]에 있는 열림 블록[25]이나 닫힘 블록[24]과 다시 재결합하게 되어, 밸브 손잡이 고정 효과를 얻을 수 있게 되는 것이다Therefore, when the handle 9 is to be rotated to open and close the ball valve 6, the movable body 22 is pushed up to the upper part of the sliding part, and then the handle is rotated in a desired direction, and then the movable body 22 is released. The moving body located on the upper side of the sliding portion naturally descends along the inclined surface and recombines with the opening block [25] or the closing block [24] in the uneven portion [27] to obtain the valve knob fixing effect. Will be

따라서, 자물쇠[28]를 채워두지 않더라도, 이동 바디의 삽입부와, 요철부의 열림 블록이나 닫힘 블록의 결합에 의해, 확실한 볼밸브 손잡이 고정 효과를 얻을 수 있으므로, 기체 및 액체 배관의 미세한 진동이나, 예기치 못한 충격에 의해, 밸브 손잡이가 회전하여 발생할 수 있는 안전사고를 사전에 방지할 수 있는 효과를 얻을 수 있게 된다Therefore, even if the lock 28 is not filled, the ball valve knob fixing effect can be secured by the combination of the insertion portion of the movable body and the opening or closing block of the uneven portion, so that minute vibrations of the gas and liquid pipes, Unexpected impact can provide an effect to prevent the safety accident that can occur due to the rotation of the valve knob.

또한, 관련도면 도1에서 도시한 바와 같이, 볼밸브[6]가 위치한 곳으로부터 원거리에서 배관[3]의 수리 작업이 이행되거나, 볼밸브가 위치한 곳으로부터 보이지 않는 곳에서의 수리 작업이 이루어지는 경우, 관련도면 도4에서 보는 바와 같이, 배관 수리 작업을 수행하는 작업자가 슬라이딩부[20] 상부에 형성되어 있는, 자물쇠 삽입구[21]에 자물쇠[28]를 채워두고, 그 열쇠를 본인이 보관하게 되면, 이동 바디[22]는 자물쇠[28]에 의해 슬라이딩부[20]의 상부로 이동할 수 없게 되며, 이는 삽입부[23]와 열림 블록[25] 또는 닫힘 블록[24]의 결합을 해제하지 못하게 하는 효과를 주게 되므로, 타인에 의해 발생할 수 있는 밸브의 개폐를 사전에 방지할 수 있게 되어, 산업 현장이나 실생활에서의 안전사고 발생을 완벽하게 방지할 수 있게 되는 것이다In addition, as shown in FIG. 1, when the repair work of the pipe [3] is performed at a distance from the place where the ball valve [6] is located, or when the repair work is performed at a place not visible from the place where the ball valve is located. As shown in FIG. 4, the operator who performs the pipe repair work fills the lock [28] in the lock insertion hole 21, which is formed on the upper portion of the sliding part 20, and keeps the key for himself. In this case, the movable body 22 cannot be moved to the upper portion of the sliding portion 20 by the lock 28, which does not disengage the insert 23 from the opening block 25 or the closing block 24. Since it is possible to prevent the opening and closing of the valve which may be caused by others, it is possible to completely prevent the occurrence of safety accidents in the industrial field or real life.

또한, 본 고안은 배관에 조립된 볼밸브 전체를 교환하지 않고, 손잡이와 요철부[27]만 교환함으로써, 교환 비용이나 교환 시간을 절약할 수 있으며, 원형바디[18]에 형성된 돌출부[19] 숫자만큼, 요철부에 형성된 절개면을 추가로 형성하게 되면, 모든 볼밸브에 적용이 가능하게 되므로, 많은 실용상의 효과가 얻어지게 된다. In addition, the present invention can save the exchange cost or replacement time by replacing only the handle and the uneven portion [27], without replacing the entire ball valve assembled in the pipe, the projection [19] formed in the circular body [18] If the number of cutouts formed on the uneven portion is additionally formed by the number, since it can be applied to all ball valves, many practical effects are obtained.
