그런데 이와 같은 파이프 커플링은 볼트와 너트를 조여서 한 쌍의 반원고리형 커플링 세그먼트(1, 2)를 파이프에 고정하는 기계적 특성상 작업자의 실수로 어느 한쪽이라도 볼트와 너트가 완전히 조여지지 않은 상태에서 파이프 내부에 높은 압력이 걸리거나 진동이 발생하면 반원고리형 커플링 세그먼트(1, 2) 간의 체결 상태가 서서히 풀리면서 누수나 파이프 이탈 등의 대형 사고를 야기하는 문제점이 있다.However, such a pipe coupling is a mechanical characteristic of fastening a pair of semi-circular coupling segments (1, 2) to a pipe by tightening bolts and nuts. When high pressure or vibration occurs inside the pipe, the fastening state between the semi-circular coupling segments 1 and 2 is gradually released, causing a large accident such as leakage or pipe detachment.
이러한 종래의 파이프 커플링이 지닌 문제점을 해결하기 위해 볼트와 너트가 견고하게 체결되었는지를 육안으로 쉽고 명확하게 확인할 수 있는 구조의 파이프 커플링이 개발되었으며, 이는 본 출원인의 등록특허공보 제10-1810063호(특허문헌 1)에 개시되어 있다.In order to solve the problems of the conventional pipe coupling, a pipe coupling has been developed that can easily and clearly determine whether the bolt and nut is firmly fastened, which is the applicant's Patent Publication No. 10-1810063 It is disclosed in the arc (patent document 1).
즉, 특허문헌 1은 반원고리형 커플링 세그먼트(제1 및 제2부재) 간의 결합 시 서로 대향하는 플랜지부에 컷팅부를 일체로 형성하고, 이들 사이에 식별지를 끼워서 볼트와 너트의 조임으로 플랜지부들의 간격이 일정 범위 이내가 되면 컷팅부가 식별지를 잘라내도록 함으로써 볼트와 너트가 완전히 조여진 상태로 반원고리형 커플링 세그먼트들이 견고하게 체결되었음을 육안으로 쉽고 명확하게 확인할 수 있다.That is, Patent Literature 1 forms a cut portion integrally with the flange portions facing each other when the semi-circular coupling segments (first and second members) are coupled to each other, and inserts an identification sheet therebetween to tighten the bolts and nuts. When the gap is within a certain range, the cutting unit cuts out the identification sheet so that the semicircular coupling segments are firmly fastened with the bolts and nuts completely tightened.
그러나 이는 두 파이프의 연결을 위해 반원고리형 커플링 세그먼트들을 결합할 때 아래쪽에 위치하는 반원고리형 커플링 세그먼트의 플랜지부에 식별지를 대충 올려놓은 상태로 볼트와 너트를 조이거나 작업자가 위쪽에 위치하는 반원고리형 커플링 세그먼트들의 플랜지부에 식별지를 한 손으로 밀착시킨 상태에서 아래쪽에 위치하는 반원고리형 커플링 세그먼트를 대향시킨 후 볼트를 끼우고 너트를 조여야 하기 때문에 조립 작업이 상당히 까다롭고 불편할 수밖에 없는 사용상의 한계가 있다.However, this means that when joining the semicircular coupling segments for the connection of two pipes, the bolts and nuts are tightened or the operator is placed on the flange part of the semicircular coupling segment located below. The assembly work is very difficult and inconvenient, because it is necessary to insert the bolt and tighten the nut after opposing the semicircular coupling segment located at the bottom with one hand contact with the flange part of the semicircular coupling segments. There is a limit to use.
더욱이 플랜지부에서 약간 돌출 형성된 컷팅부에 식별지를 안정적으로 끼우기 위해서는 식별지의 요철부 부분을 컷팅부와 서로 대응되도록 위치시켜야만 하는 불편함이 있다.In addition, in order to stably insert the identification portion to the cutting portion slightly protruded from the flange portion, there is an inconvenience in that the uneven portion of the identification sheet must be positioned to correspond to the cutting portion.

It is formed so that it can be fastened with the bolt 50 and the nut 60 in the state which wraps the part which abuts together.
그리고 제1부재(11)와 제2부재(12)가 서로 대칭적으로 배치될 때 플랜지(16)들 끼리 서로 마주하는 면의 관통구멍(17) 주위에는 식별부재(30)를 결합하기 위한 안착홈(19)이 형성되어 있다.And when the first member 11 and the second member 12 are disposed symmetrically with each other, the seating for coupling the identification member 30 around the through hole 17 on the surface of the flanges 16 facing each other The groove 19 is formed.
또한, 제1부재(11)와 제2부재(12)의 서로 마주하는 플랜지(16) 면에는 제1부재(11)와 제2부재(12)가 어긋나게 결합되거나 상대적으로 이동되는 것을 방지하는 스토퍼(22) 및 스토퍼 구멍(23)이 암수 형상으로 서로 대응되게 형성되어 있고, 지지홈(14)의 내벽에는 볼트(50)와 너트(60)를 체결 시 밀봉부재(40)를 더욱 효과적으로 압축하고 지지홈(14) 내에서의 비틀림을 방지할 수 있도록 눌러 잡아주는 웨지(24)가 적어도 하나 이상으로 돌출 형성되어 있다.In addition, a stopper for preventing the first member 11 and the second member 12 from being misaligned or relatively moved on the flange 16 faces of the first member 11 and the second member 12 facing each other. 22 and the stopper hole 23 are formed to correspond to each other in the shape of a male and female, and the inner wall of the support groove 14 to more effectively compress the sealing member 40 when fastening the bolt 50 and the nut 60 At least one protruding wedge 24 is formed to be pressed to prevent twisting in the support groove 14.
여기서 볼트구멍(18)은 제1부재(11)와 제2부재(12)를 결합 시 볼트(50)의 나사부를 단번에 집어넣기 편리하면서 너트(60)의 체결이 용이하도록 장공홀(slot hole) 형상으로 형성되는 것이 바람직하다.Here, the bolt hole 18 is a slot hole to facilitate the fastening of the nut 60 while conveniently fitting the screw portion of the bolt 50 at the time of coupling the first member 11 and the second member 12. It is preferable that it is formed in a shape.
아울러 관통구멍(17)은 볼트구멍(18)의 내경보다 약간 크게 형성되는 것이 바람직하다.In addition, the through hole 17 is preferably formed to be slightly larger than the inner diameter of the bolt hole 18.
한편, 너트(60)가 외력에 의해 느슨해져서 죔이 풀리거나 이완되는 것을 방지하기 위하여 너트(60)와 플랜지(16)의 볼트구멍(18) 주위 대향면에는 마찰력을 증대시켜 미끄러짐을 막는 톱니 모양의 요철(21)(61)이 각각 형성되어 있다.On the other hand, in order to prevent the nut 60 from being loosened due to an external force and loosening or loosening, the opposite surface around the bolt hole 18 of the nut 60 and the flange 16 increases the frictional force and prevents slippage. Irregularities 21 and 61 are formed, respectively.
커팅날(20)은 제1부재(11)와 제2부재(12)를 두 파이프의 서로 맞닿는 부분을 함께 감싼 상태로 볼트(50)와 너트(60)를 체결할 때 상호 간의 간격이 일정 범위 이내가 되면 식별부재(30)의 파단부(34)를 잘라내기 위해 플랜지(16)의 가장자리에 일체로 형성되어 있다.The cutting blade 20 has a predetermined range when the bolt 50 and the nut 60 are fastened together with the first member 11 and the second member 12 wrapped together with the two pipes in contact with each other. When it is within, it is integrally formed at the edge of the flange 16 to cut the break 34 of the identification member 30.
즉, 커팅날(20)은 제1부재(11)와 제2부재(12)가 완전히 결합되면, 다른 커팅날(20)과 서로 교차하면서 식별부재(30)의 파단부(34)를 잘라내기 위해 그 끝부분으로 갈수록 점차 폭이 좁아지거나 날카롭게 형성되어 있다.That is, when the first member 11 and the second member 12 are completely coupled, the cutting blade 20 cuts the break 34 of the identification member 30 while crossing each other with the cutting blade 20. Towards its end, the width becomes narrower or sharper.
식별부재(30)는 제1부재(11)와 제2부재(12)의 서로 마주하는 플랜지(16)들 사이에 끼울 수 있도록 형성되어 있고, 제1 및 제2부재(11)(12)의 관통구멍(17)과 볼트구멍(18)에 볼트(50)의 나사부를 집어넣고, 너트(60)를 죄어 제1부재(11)와 제2부재(12)를 결합할 때 커팅날(20)에 의해 플랜지(16)의 외부로 돌출된 일부분은 파단되도록 형성되어 있다.The identification member 30 is formed to be sandwiched between the flanges 16 of the first member 11 and the second member 12 facing each other, and the first and second members 11 and 12 Cutting blade 20 when inserting the threaded portion of the bolt 50 into the through hole 17 and the bolt hole 18 and tightening the nut 60 to join the first member 11 and the second member 12. The portion which protrudes out of the flange 16 by this is formed so that it may be broken.
그리고 식별부재(30)는 플랜지의 안착홈(19)에 일부분이 압입 방식으로 끼워지는 걸림부(31)가 형성되어 있고, 이 걸림부(31)의 한쪽 면에는 탄성에 의해 탄력적으로 변형되면서 관통구멍(17)에 압입 방식으로 끼워지는 삽입부(32)가 일체로 돌출 형성되어 있고, 볼트(50)를 집어넣을 수 있도록, 즉 제1 및 제2부재(11)(12)의 관통구멍(17)과 볼트구멍(18)에 볼트(50)의 나사부를 집어넣을 수 있도록 걸림부(31)와 삽입부(32)를 상하로 관통하는 장공(33)이 형성되어 있으며, 걸림부(31)의 다른 한쪽 면에는 커팅날(20)에 의해 파단되는 파단부(34) 일체로 돌출 형성되어 있다.In addition, the identification member 30 has a locking portion 31 in which a part is fitted in a seating groove 19 of the flange by a press-fit method, and one side of the locking portion 31 is elastically deformed by elasticity and penetrates therethrough. The insertion part 32 fitted in the hole 17 in a press-fitting manner is integrally formed to protrude, so that the bolt 50 can be inserted, that is, the through hole of the first and second members 11 and 12. 17 and the long hole 33 which penetrates the locking part 31 and the insertion part 32 up and down so that the screw part of the bolt 50 may be inserted into the bolt hole 18, and the locking part 31 is formed. The other side of the protruding portion 34 is formed integrally broken by the cutting blade (20).
아울러 파단부(34)의 가운데 부분에는 커팅날(20)들의 교차 시 용이하게 파단되면서 쉽게 잘려나갈 수 있도록 하는 슬릿(35)이 형성되어 있고, 걸림부(31)보다 상대적으로 두께가 얇게 형성되어 있다.In addition, a slit 35 is formed at the center portion of the break 34 so that the cutting blades 20 can be easily broken while being cut, and the thickness is relatively thinner than the catching portion 31. have.
여기서 식별부재(30)는 외력을 받을 시 탄력적인 변형이 일어나도록 약간의 탄성을 갖는 나일론 수지, 폴리에스터 수지, 플라스틱(PE, PP, PVC, PS, ABS, AS, MA, PVAL, PET) 수지 등의 합성수지로 사출성형할 수 있다.Here, the identification member 30 is a nylon resin, polyester resin, plastic (PE, PP, PVC, PS, ABS, AS, MA, PVAL, PET) resin having a slight elasticity so that elastic deformation occurs when subjected to external force Injection molding can be carried out with synthetic resins such as these.
또한, 식별부재(30)는 제1부재(11) 및 제2부재(12)와 색상을 다르게 함으로써 볼트(50)와 너트(60)가 완전히 조인 상태를 더욱 정확하고 효과적으로 확인할 수 있다.In addition, the identification member 30 may check the state in which the bolt 50 and the nut 60 are completely tightened more accurately and effectively by different colors from the first member 11 and the second member 12.
이와 같이 구성된 본 발명의 실시 예에 따른 파이프 커플링은, 볼트(50)와 너트(60)의 조임에 따라 제1부재(11)와 제2부재(12)가 서로를 향해 당겨져 간격이 가까워지면서 밀봉부재(40)에 자연스럽게 압력이 가해지고, 이렇게 되면 밀봉부재(40)가 변형되어 두 파이프와의 간극을 막아준다.In the pipe coupling according to the embodiment of the present invention configured as described above, the first member 11 and the second member 12 are pulled toward each other as the bolt 50 and the nut 60 are tightened to close each other. Pressure is naturally applied to the sealing member 40, which causes the sealing member 40 to deform to prevent a gap between the two pipes.
이때, 커팅날(20)들이 교차하면서 식별부재(30)의 파단부(34)를 가압하여 파단시키므로 볼트(50)와 너트(60)가 한쪽으로 편중됨 없이 완전히 체결되었는지를 육안으로 신속하고 명확하게 확인할 수 있다.At this time, since the cutting blades 20 intersect and break the pressing portion 34 of the identification member 30, it is quick and clear to the naked eye whether the bolt 50 and the nut 60 are fully engaged without being biased to one side. You can check it.
더구나 식별부재(30)가 제2부재(또는 제1부재)의 플랜지(16)에 억지 끼워맞춤 방식으로 끼워져 그 결합 상태를 유지하므로 제1부재(11)를 대향시킨 후 볼트(50)를 끼우고 너트(60)를 조일 때 종래와 달리 작업자가 한 손으로 식별부재(30)를 플랜지(16)에 밀착시킨 상태로 작업할 필요가 없어 두 파이프의 연결을 위한 조립 작업이 신속하고 용이하면서 효율적으로 이루어질 수 있다.In addition, since the identification member 30 is fitted to the flange 16 of the second member (or the first member) in a force-fitting manner and maintains its engagement state, the bolt 50 is inserted after facing the first member 11. Unlike the related art, when tightening the nut 60, the operator does not need to work with the identification member 30 in close contact with the flange 16 with one hand, so the assembly work for connecting the two pipes is quick, easy and efficient. Can be made.
즉, 식별부재(30)의 걸림부(31) 일부가 플랜지(16)의 안착홈(19)에 압입 방식으로 끼워지고, 이와 동시에 삽입부(32)가 탄성에 의해 탄력적으로 변형되면서 관통구멍(17)에 압입 방식으로 끼워지므로 볼트(50)를 끼우고 너트(60)를 조이기 전에 제1부재(11) 또는 제2부재(12)에 결합된 상태를 안정적으로 유지할 수 있다.That is, a part of the engaging portion 31 of the identification member 30 is fitted into the seating groove 19 of the flange 16 in a press-fitting manner, and at the same time the insertion portion 32 is elastically deformed by elasticity and the through hole ( Since it is fitted in the press-fit method 17, it is possible to stably maintain the state coupled to the first member 11 or the second member 12 before the bolt 50 is inserted and the nut 60 is tightened.
그뿐만 아니라 식별부재(30)의 결합력으로 인해 제1부재(11)와 제2부재(12)의 유동을 최소화하고, 밀봉부재(40)를 보다 균일하게 가압하여 유체의 누설 없이 더 높을 압력을 견딜 수 있다.In addition, due to the coupling force of the identification member 30, the flow of the first member 11 and the second member 12 is minimized, and the sealing member 40 is pressurized more uniformly so that a higher pressure can be obtained without leakage of the fluid. Can withstand
한편, 도 5에 도시된 바와 같이 식별부재(30-1)의 삽입부(32) 외주연에는 플랜지의 관통구멍(17)에 더욱 유연하고 탄력적이면서 안정적으로 끼워진 상태를 유지할 수 있도록 하는 밀착돌기(36)가 일정한 간격을 두고 다수 형성될 수 있다.On the other hand, as shown in Figure 5 the outer periphery of the insertion portion 32 of the identification member (30-1) is a close contact protrusion to maintain a more flexible, elastic and stable fit in the through hole 17 of the flange ( 36 may be formed at regular intervals.
또한, 도 6 및 도 7에 도시된 바와 같이 식별부재(30-2)의 삽입부(32) 자유단부에는 볼트구멍(18) 속에 끼워져 장공(33) 속으로 볼트(50)의 나사부를 집어넣기 용이하도록 안내하는 중공형 안내부(37)가 일체로 돌출 형성될 수 있다.In addition, as shown in FIGS. 6 and 7, the free end of the insertion portion 32 of the identification member 30-2 is inserted into the bolt hole 18 to insert the screw portion of the bolt 50 into the long hole 33. Hollow guide portion 37 for guiding easily may be integrally formed to protrude.
즉, 안내부(37)는 삽입부(32)의 길이를 볼트구멍(18)의 내주연까지 연장하듯이 끼워지고 그 중공이 장공(33)과 통하기 때문에 볼트(50)의 나사부를 볼트구멍(18) 속에 집어넣을 때 삽입부(32)의 장공(33)이 그 볼트구멍(18)과 정확하게 일직선상에 위치되지 않으면 삽입부(32)의 자유단부와 접촉 간섭이 일어나 쉽게 들어가지 않는 불편함을 해소할 수 있다.That is, the guide part 37 is fitted as the length of the insertion part 32 extends to the inner periphery of the bolt hole 18, and since the hollow communicates with the long hole 33, the threaded part of the bolt 50 is the bolt hole ( 18) If the long hole 33 of the insertion portion 32 is not exactly in line with the bolt hole 18 when it is inserted into it, contact interference with the free end of the insertion portion 32 is not convenient and does not enter easily. Can be solved.
한편, 도 8 및 도 9에 도시된 바와 같이 바디(13)의 양쪽 중 한쪽 플랜지(16)에 형성된 커팅날(20)과, 다른 한쪽의 플랜지(16)에 형성된 커팅날(20)이 서로 교차하면서 식별부재(30)의 파단부(34)를 자르도록 형성되어 있고, 아울러 커팅날(20)들이 서로 엇갈리면서 교차하도록 그 각각의 커팅날(20)은 각기 대응하는 형상의 한 쌍으로 양분하여 형성될 수 있다.Meanwhile, as shown in FIGS. 8 and 9, the cutting blade 20 formed on one flange 16 of both sides of the body 13 and the cutting blade 20 formed on the other flange 16 cross each other. While being formed to cut the break 34 of the identification member 30, and the cutting blades 20 are alternately intersected with each other, each of the cutting blades 20 is bisected into a pair of the corresponding shape, respectively Can be formed.
즉, 커팅날(20)은 두 개의 날이 서로 교차하는 작용으로 식별부재(30)의 파단부(34)를 한층 더 용이하고 수월하게 파단할 수 있어 볼트(50)와 너트(60)가 완전히 조여진 상태를 정확하게 확인할 수 있다.That is, the cutting blade 20 can more easily and easily break the break 34 of the identification member 30 by the action of the two blades intersecting each other, so that the bolt 50 and the nut 60 are completely The tightness can be checked accurately.
여기서 커팅날(20)들은 도 9에 도시된 바와 같이 서로 엇갈리면서 교차하도록 그 각각의 커팅날(20)은 서로 대응하는 하나의 형상으로 형성될 수도 있다.Here, the cutting blades 20 may be formed in one shape corresponding to each other so that the cutting blades 20 alternately cross each other as shown in FIG. 9.
