본 고안은 배관을 상호 연결시키는 배관이음용 커플링에 관한 것으로 배관과 배관의 관이음부분에 경질링을 이용하여 가공작업을 단순화시키고 관이음을 견고하고 확실하게 한 것이다.The present invention relates to a pipe joint coupling that interconnects pipes, and uses hard rings in pipes and pipe joints to simplify processing and to make pipe joints firm and secure.
종래의 이음용 커플링은 연결하고져하는 배관과 배관의 서로 맞닿는 이음부분의 끝단외경에 밀폐용 패킹을 끼우고 그 외측외경과 상, 하부커플링의 내주면에는 요철구를 서로 대향지게 형성시켜 상,하부 커플링을 볼트, 너트로서 체결시 양쪽배관의 이음부분 와경과 상,하부커플링의 내주면에 서로 대향지게 형성된 요철구가 서로 맞물려서 고정되도록 한 것으로 이음부분의 외경과 상, 하부커플링의 내주면에 서로 대향되는 요철구를 일치되게 형성시키기 위한 가공작업이 난이할 뿐만 아니라 이렇게 서로 대향되는 요철구가 사이빈틈이 없이 완전히 일치가 되지 않는 경우에는 양쪽 배관이 완전하게 고정되지 못하는 폐단이 있었다.Conventional joint couplings are fitted with sealing seals on the outer circumferential diameters of the pipes to be connected and the joint portions of the pipes connected to each other, and the outer circumference and the upper and inner circumferential surfaces of the lower coupling are formed to face each other. When tightening the lower coupling as bolts and nuts, the inner and outer surface of the joint and the inner and outer surfaces of the upper and lower couplings are fixed so that the concave and convex holes formed opposite to each other on the inner circumferential surfaces of the upper and lower couplings are engaged with each other. In addition to the difficulty of forming the convex concave and convex concave and convex concave and convex concave convex concave and convex concave convex concave and convex concave convex concave and convex concave and convex concave and convex concave and convex concave convex concave and convex concave and convex concave convex concave convex concave and convex concave convex convex concave convex concave convex concave
본 고안에서는 이와 같은 문제점을 개선하기 위하여 연결하고져 하는 양쪽배관의 이음부분에 요철구를 형성시키지 않고 일단이 절취되어 사이간격이 형성된 경질링이나 또는 상,하부 두개체로 분리된 경질링을 이음부분의 양쪽외경에 끼우고 상,하부 커플링의 내주면 중간에 형성된 패킹 삽입홈의 양쪽 내주면에는 양측경사면홈을 형성시켜서 이에 경질링의 상부가 협착되도록 하여 상,하부 커플링을 볼트, 너트로서 체결시키면 경질링이 내향으로 압축되면서 경질링의 내주면에 형성시킨 수개의 톱니형 돌조가 양쪽 배관의 이음부분 외경을 견고하게 고정시키는 것으로 도면에 의거 상세히 설명하면 다음과 같다.In order to improve such a problem, the present invention does not form irregularities in the joints of both pipes to be connected, so that one end is cut and a hard ring having a gap between the hard rings separated from the upper and lower two bodies is formed. It is inserted into both outer diameters, and both inner circumferential surfaces of the packing insertion groove formed in the middle of the inner circumferential surface of the upper and lower couplings are formed with both inclined surface grooves so that the upper part of the hard ring is narrowed. Several indentations formed on the inner circumferential surface of the hard ring while the ring is compressed inwardly to firmly fix the outer diameter of the joint portions of both pipes.
연결하고져 하는 양쪽배관(1)(1a)의 이음부분의 끝단을 밀폐용패킹(2)의 양쪽내부로 양단이 맞닿이도록 삽입시키고 그 외부를 패킹삽입홈(11)이 내주면의 중간부에 형성된 상, 하부 커플링(10)(10a)으로 체결시키는 공지의 이음용 커플링에 있어서, 상,하부 커플링(10),(10a)의 내주면 중간부에 형성된 패킹삽입홈(11)의 양쪽 내주면에 양측경사면홈(12)을 형성시켜 양쪽 배관의 이음부분 외경에 끼워진 일단이 절취되어 사이간격이 형성되고 내주면에 수개의 톱니형 돌조(21)가 형성된 경질링(21)을 양측 경사면홈(12)에 협지되도록 볼트, 너트로서 체결시켜 경질링이 내향으로 압축되면서 내주면에 형성된 수개의 톱니형돌조(21)가 이음부분의 외경을 고정시키도록 된 것으로 경질링을 반원형이 되게 두개체로 절단이 되고 각 내주면에 수개의 톱니형 돌조(21)가 형성된 상,하부 경질링(20)(20a)으로 대체시킬 수도 있는 것이다.Insert the ends of the joints of both pipes (1) and (1a) to be connected so that both ends abut against both sides of the sealing packing (2), and the outside of the packing inserting groove (11) formed at the middle of the inner circumferential surface. In the known joint coupling to be fastened by the lower coupling (10) (10a), the inner and outer peripheral surfaces of the packing insertion grooves (11) formed in the middle of the inner peripheral surface of the upper, lower coupling (10), (10a) Both inclined surface grooves 12 are formed so that one end fitted to the outer diameter of the joint portion of both pipes is cut off to form a gap between the two inclined surface grooves 12 having a hard ring 21 having several serrated protrusions 21 formed on the inner circumferential surface thereof. As the bolt and nut are fastened inwardly so that the hard ring is compressed inwardly, several tooth-shaped protrusions 21 formed on the inner circumferential surface are fixed to the outer diameter of the joint. The hard ring is cut into two pieces so as to be semicircular. Several serrated protrusions 21 on the inner circumference The phase, that may be replaced by a lower rigid ring (20) (20a).
이와 같은 구조로 된 본 고안의 연결방법을 설명하면 우선 연결하고져 하는 양쪽 배관의 이음부분 외경에 경질링(20)을 일단이 절취된 사이간격(22)을 탄력으로 이용하여 끼운 후 양쪽 배관의 이음부분의 끝단을 밀폐용패킹(2)의 양쪽 내부로 삽입시켜 끝단이 서로 맞닿이도록 일치시킨 후 상, 하부커플링(10)(10a)으로 내주면 가운데 형성된 패킹삽입홈(11)에는 밀폐용패킹을, 그 양쪽에 형성된 양측경사면홈(12)에는 경질링(20)이 협지되도록 하여 볼트, 너트로서 체결시키면 양측경사면홈에 경질링의 상부가 협착되어 상, 하부커플링의 내주면에 경질링이 고정되면서 경질링 전체를 내향으로 압축시켜 일단이 절취되어 사이간격이 형성된 경질링이나 또는 반원형이 되게 두개체로 절단된 상,하부 경질링(20)(20a)의 내경이 축소가 되면서 내주면에 형성된 수개의 톱니형 돌조(21)가 양쪽 배관의 이음부분의 외경을 고정시켜서 양쪽 배관이 견고하게 연결되는 것이다.When explaining the connection method of the present invention having such a structure, first, by inserting the rigid ring 20 to the outer diameter of the joint portion of the both ends of the pipe to be connected by elastically inserting the gap 22 between one end is cut elastically Insert the ends of the parts into both sides of the sealing packing (2) to match the ends to abut each other, and then seal packing in the packing insertion groove (11) formed in the inner circumferential surface of the upper, lower coupling (10) (10a) When both sides of the inclined surface grooves 12 are formed on both sides of the hard ring 20 to be clamped by bolts and nuts, the upper surfaces of the hard rings are squeezed to the two inclined surface grooves so that the hard rings are fixed to the inner circumferential surfaces of the upper and lower couplings. While compressing the entire hard ring inwards, one end is cut off and the inner ring of the upper and lower hard rings 20 and 20a cut into two pieces to be formed into a semicircular shape or a semicircle is reduced, and the number formed on the inner circumferential surface thereof. Saw-tooth ridges 21 is fixed by the outer diameter of the joint part of the both pipes will be both pipes are firmly connected.
이상과 같이 본 고안은 경질링을 이용하여 양쪽 배관의 이음부분에 요철구와 같은 별도의 가공공정이 필요없이 간단한 구조와 구성으로 견고하게 연결시킬 수가 있는 것이다.As described above, the present invention is to use a hard ring can be firmly connected in a simple structure and configuration without the need for a separate processing process, such as irregularities in the joints of both pipes.
