본 발명은 합성수지관의 접속장치에 관한 것으로, 더욱 상세하게 설명하면, 양측 단부에 플랜지가 형성된 합성수지관의 연결을 위한 접속장치에 관한 것으로, 양측에 경사부가 형성된 체결링의 하단에는 힌지부가 형성되고, 상단에는 볼트 체결부가 형성되어 플랜지의 외주면에 끼운 후 볼트를 체결함에 따라 플랜지 사이에 내재된 접속링과 그 양단에 형성된 패킹에 의해 수밀이 달성되는 경사진 플랜지를 가진 합성수지관의 접속장치에 관한 것이다.The present invention relates to a connection device of a synthetic resin pipe, and more specifically, to a connection device for connecting a synthetic resin pipe with a flange formed at both ends, the hinge portion is formed at the lower end of the fastening ring is formed on both sides The upper end of the bolt is formed in the joint of the flange, and after the bolt is fastened to the connection device of the synthetic resin pipe having a slanted flange is achieved watertight by the connection ring inherent between the flange and the packing formed at both ends will be.
일반적으로 지중에 매설되는 합성수지관은 주로 상 ·하수 등과 같은 비압력유체의 이송용이나 전선 및 각종 케이블 등의 배선 시 그 외측에 보호용으로 쓰이며, 가볍고 내식성이 양호할 뿐만 아니라 성형성이 우수하고, 가격이 저렴하여 다양한 용도로 사용되는 바, 상 ·하수도관 등 일상적인 것에서부터 각종 공업용 시설에 이르기까지 광범위하게 쓰인다.In general, synthetic resin pipes buried in the ground are mainly used for the transfer of non-pressure fluids such as water and sewage, and for the protection of the wires when wiring such as electric wires and various cables. Due to its low price, it is used for various purposes, and it is widely used from everyday things such as water and sewage pipes to various industrial facilities.
그 중 대표적인 합성수지관은 폴리에틸렌을 이용하여 압출하거나 원통의 형태로 감으면서 융착시키는 것이 가장 널리 사용되며, 상기 공정에 의해 일정한 길이로 생산하되, 양측단에는 플랜지가 일체로 형성된 형태로 생산되어, 실제 배관공사의 현장에서는 개별적으로 생산된 관을 하나씩 플랜지 이음을 통해 연속적인 배관을 형성하게 된다.Among them, a typical synthetic resin pipe is most widely used by extrusion using polyethylene or fusion while winding in the form of a cylinder, and is produced in a predetermined length by the above process, but is produced in a form in which flanges are integrally formed at both ends. In the field of plumbing, individual pipes are continuously piped together to form continuous pipes.
상기와 같이 플랜지가 형성된 합성수지관의 연결방법은, 양단에 형성된 플랜지를 서로 맞댄 다음 그 둘레에 형성된 다수개의 볼트공을 천공하고, 그에 볼트를 끼운 후 너트로 체결하여 합성수지관을 연결하되, 그 사이에 링형태의 패킹을 삽입하여 합성수지관과 인접하는 합성수지관 사이가 수밀하도록 하는 바, 이는 플랜지와 플랜지 사이에 단순히 패킹을 삽입하여 수밀성을 갖도록 한 구조이어서 그 수밀성은 패킹 하나에 의존할 수밖에 없었고, 이로 인해 작은 외력에 의해서도 연결부 사이가 벌어져서 누수 현상이 발생하게 되며, 장기간 사용 시 연결 볼트가 풀어지거나 패킹이 노후되어 수밀을 유지할 수 없는 문제점을 내포하고 있었다.Connection method of the synthetic resin pipe with a flange formed as described above, the flanges formed at both ends of each other and then drilled a plurality of bolt holes formed around the thread, and then screwed in the bolts to connect the synthetic resin pipe, between By inserting a ring-shaped packing into the watertight resin tube and the adjacent synthetic resin tube, the watertightness is achieved. This is a structure in which watertightness is achieved by simply inserting a packing between the flange and the flange. As a result, even a small external force is generated between the connection parts, thereby causing a water leakage phenomenon. In the long-term use, the connection bolt is loosened or the packing is aging, which may cause watertightness to be maintained.
이에 본 발명은 상기와 같은 문제점을 감안하여 발명한 것으로, 양측으로는 경사부가 형성된 링형태의 체결링을 제작하되, 하단에는 힌지부를 형성시키고, 상단에는 볼트 체결부를 형성시켜서, 이를 플랜지의 외주면에 끼워 볼트로 체결함으로써 체결링이 플랜지의 경사면을 따라 점진적으로 가압되어 플랜지의 외주면에는 동일한 체결력이 작용하여 플랜지와 플랜지 사이에 보다 확실한 체결을 이루도록 하며, 용이한 시공성으로 작업의 능률이 향상되도록 함을 목적으로 한다.Accordingly, the present invention has been invented in view of the above problems, but on both sides, a ring-shaped fastening ring having a slope is formed, but a hinge part is formed at the lower end, and a bolt connection part is formed at the upper end thereof, which is formed on the outer circumferential surface of the flange. By fastening with bolts, the fastening ring is gradually pressed along the inclined surface of the flange so that the same fastening force acts on the outer circumferential surface of the flange to achieve a more secure fastening between the flange and the flange, and the workability is improved to improve work efficiency. The purpose.
또한, 플랜지와 플랜지 사이 내부에는 접속링을 설치하되, 접속링의 양단으로는 패킹이 각각 형성되어, 상기 체결링을 체결하게 되면 플랜지가 상호 밀착되면서 그에 내재된 접속링이 가압되어 완벽한 수밀을 이룰 수 있도록 함을 목적으로한다.In addition, a connection ring is installed between the flange and the inside of the flange, and packings are formed at both ends of the connection ring. When the fastening ring is fastened, the flanges are in close contact with each other, so that the connection rings inherent therein achieve perfect watertightness. It is intended to be.
