Abstract
본 고안은 대형 강관의 관이음구용으로 사용되는 탄력성 있는 고무로된 밀폐링에 관한 것이다.The present invention relates to a resilient rubber sealing ring used for pipe fittings of large steel pipes.
종래의 관이음구용 밀폐링은 이의 구조가 단조롭고 이음 각도에 적응력이 미흡할 뿐만 아니라, 높은 수압을 받으면 연결 관체가 이음구의 밀폐링에서 쉬히 빠지거나 이완되어 누수 되거나 파손되어지는 폐단이 있었던 것이다.The conventional sealing ring for the pipe fittings is not only monotonous in structure and insufficient adaptability to the joint angle, but also when the high water pressure is applied, the connection pipe is easily leaked or loosened from the sealing ring of the joint, and there is a closed end.
본 고안은 이상의 문제점을 해결하고자 안출한 것으로, 이의 고안 요지는 탄성 고무로된 밀페링 몸체(1)의 내주면 좌우단에는 패킹(5)이 끼움되는 끼움홈(3)이 형성되고, 중간부에 형성된 걸림턱(2)의 좌우측에는 외향경사 된 신축부(4)와 내향 경사홈으로된 역지턱(4')을 형성하여 이를 밀폐링으로 사용하게되면 외향 경사진 신축부에는 관체의 이음 상태가 직선이 되지 못하고 휘임하거나 비틀림 생길때는 이에 적응되어 압을 구루 받을 수 있게 하고, 높은 수압을 받아 관체가 밀폐링 몸체(1)로부터 삐질려고 할 대에는 내향 경사요임된 역지턱(4')이 역지 기능을 하면서 관체의 빠짐 현상을 방지할 수 있게 한 것이다.The present invention is devised to solve the above problems, the subject matter of the present invention is formed in the left and right ends of the inner circumferential surface of the sealing ring body (1) made of elastic rubber fitting groove (3) is formed, the middle portion On the left and right sides of the formed locking jaw (2) formed an outwardly inclined expansion and contraction portion (4) and an inwardly inclined groove (4 ') made of inward inclined grooves when used as a sealing ring, the outwardly inclined expansion and contraction of the expansion joint is the state of the joint When bending or torsion occurs without being a straight line, it is adapted to this and receives pressure. When the tube is to be squeezed out of the sealing ring body 1 under high water pressure, the inwardly inclined stationary jaw 4 'is lifted. While functioning to prevent the fall of the tube.
Description
본 고안은 상하수도 설치시에 주로 사용하는 대형강관의 관이음구용 밀폐링에 관한 것이다.The present invention relates to a sealing ring for pipe fittings of large steel pipes mainly used in the installation of water and sewage.
종래의 대형강관의 관이음구용 밀폐링은 관의 이음 상태가 직선하지 못하고 비틀림되거나 휘임 되었을 때는 이에 적응력이 미흡하고 또한, 높은 수압을 받으면 관체가 빠지거나 이완되어 누수도거나 파손되는 폐단이 있었던 것이다.The sealing ring for pipe fittings of conventional large steel pipes has insufficient adaptation force when the pipe joint state is not straight and is twisted or bent, and when there is a high water pressure, there is a closed end that leaks or breaks due to the pipe being pulled out or relaxed. .
본 고안은 이상의 문제점을 해결하고자 안출한 것으로, 이의 고안 요지는 좌우단에 형성된 끼움홈에 패킹이 끼움되게한 탄성 고무로된 밀폐링 몸체의 외주 및 내주 중간부에 걸림턱이 형성된 것에 있어서 내주 중간부에 형성된 걸림턱의 좌우측에 외향 경사진 신축부와 내향 요입된 역지턱을 형성하여 이에 끼움된 관체의 연결 상태가 직선이 아니고 휘임되거나 비틀림이 생길시에는 신축부에 의해 쉬히 적응되게하고 관체가 높은 압을 받을 때는 역지턱의 역지 기능에 의해 관체의 빠짐현상이나 파손현상을 방지 할 수 있게한 것이다.The present invention is devised to solve the above problems, the subject matter of the present invention is the middle of the inner periphery in the locking jaw formed in the outer circumference and the inner circumferential middle portion of the sealing ring body made of elastic rubber that the packing is fitted to the fitting groove formed on the left and right An outwardly inclined stretchable part and an inwardly recessed inlet jaw are formed on the left and right sides of the engaging jaw formed in the part so that when the connected state of the inserted tube is not straight but bent or twisted, it is easily adapted by the elastic part. When high pressure is applied, it is possible to prevent the phenomenon of tube falling out or damage by the check function of the check jaw.

탄성 고무로된 밀폐링 몸체(1)의 좌우측 내부에는 끼움홈(3)을 형성하여 실리콘등의 내마모성 수지로된 패킹(5)이 끼움되게 하고, 몸체(1)의 내주면 중간부에 형성된 걸림턱(2)의 좌우측에는 외향으로 경사 요입된 신축부(4)와 내향경사 요입된 역지턱(4')이 돌설되고, 몸체(1)의 외주면 중간부에는 좌우 관이음구(6), (6')가 접지되는 걸림턱(2')이 형성되어진 구조이다Forming grooves 3 are formed in the left and right sides of the sealing ring body 1 made of elastic rubber so that the packing 5 made of abrasion-resistant resin such as silicone is fitted, and the locking step formed in the middle of the inner circumferential surface of the body 1. The left and right sides of (2) are inclined outwardly inclined (4) and inwardly inclined inverted jaw (4 '), and the outer peripheral surface of the body (1) in the middle of the left and right pipe joints (6), (6' ) Is a structure in which a locking step 2 'to which ground is formed is formed.
이상과 같이 구성된 본 고안은 상하수도 설치시 사용되는 대형강관의 관이음구용 밀폐링으로 사용하는 것인 바, 이를 사용할 시는 제3도에 예시한 바와 같이 이음되는 좌우 관체를 몸체(1)의 내주벽 중앙부에 형성된 걸림턱(2)에 접지시킴과 동시에 몸체(1)의 외주면 중심부에 형성된 걸림턱(2')에는 좌우관이음구(6), (6')를 접지시켜 프렌지부에 형성된 통공으로 체결 볼트(7)를 끼운후 너트(7')로 조임하면 되는 것으로 이와 같이하여 사용하게 되면 배관시나 배관후에 있어 지반 이동 등으로 관체의 이음 상태가 직선상이 되지 못하고 휘임되거나 비틀림 될시는 밀폐링 몸체(1) 내주면 좌우측에 형성된 외향 경사진 신축부(4)가 신축되면서 비틀림된 관체의 변형된 각도에 용이하게 적응되기 때문에 밀폐링 몸체(1)에는 힘이 고루 전달되므로 안전성이 있고, 관체내에 높은 수압이 가해지면 이 높은수압에 의해 관체가 이탈하려고 할 때는 신축부(4)에 인접 형성된 내향경사 요입된 역시턱(4')이 역지기능을 하여주기 때문에 좌우 관체가 빠질려는 현상을 방지하게 된다.The present invention configured as described above is to be used as a sealing ring for the pipe fitting of the large steel pipe used in the installation of water and sewage, when using this, the left and right pipe bodies to be joined as illustrated in FIG. At the same time as grounding to the engaging jaw (2) formed in the central wall of the main wall and at the center of the outer circumferential surface of the body 1, the left and right pipe fittings (6), (6 ') to ground through the hole formed in the flange portion Insert the fastening bolt (7) and tighten it with the nut (7 '). If it is used in this way, if the joint state of the pipe cannot be straight due to ground movement during piping or after piping, it will be closed or twisted. Since the outwardly inclined stretchable portion 4 formed on the left and right sides of the body 1 is easily adapted to the deformed angle of the torsional tube body as it is stretched, the sealing ring body 1 has safety because the force is evenly transmitted. When high water pressure is applied to the body, when the tube is to be separated by this high water pressure, the inward inclined indentation adjacent to the stretchable part 4, 4 ', which acts as a reverse function, causes the left and right body to fall out. Will be prevented.
이상과 같이 본 고안은 몸체(1)의 내주면 중심부에 형성된 걸림턱(2)의 조우측에 외향 경사홈으로된 신축부(4)와 내향 경사 요입된 역지턱(4')을 형성하였기 때문에 배관시나 배관 후에 있어 지반 변동 등으로 이음 관체의 각도변경이 있을 때는 신축부(4)에 형성된 외향 경사부가 이에 쉬히 적용할 뿐만아니라 높은 수압을 받을때는 내향 경사 요입되니 역지턱(4')이 역지기능을 하면서, 관체의 빠짐현상이나 밀폐링 몸체(1)의 파손현상을 방지할 수 있어서 매우 실용적이다.As described above, since the present invention has formed an expansion and contraction portion 4, which is an outwardly inclined groove, and an inwardly inclined inlet recess 4 'on the jaw side of the locking jaw 2 formed at the center of the inner circumferential surface of the body 1, When there is a change in the angle of the joint pipe due to ground fluctuations after pipes or pipes, the outward inclined portion formed on the stretchable part 4 is easily applied to it, and when the high water pressure is received, the inward inclination is recessed. While doing so, it is possible to prevent the phenomenon of the tube falling out and the damage of the sealing ring body (1) is very practical.
