원통형 파이프 접속연결장치{A APPARATUS FOR CONNECTING PIPE}Cylindrical pipe connecting device {A APPARATUS FOR CONNECTING PIPE}

본 발명은 2개의 원통형 파이프를 연통되도록 일체형으로 연결시켜 주는 원통형 파이프 접속연결장치에 관한 것이다.The present invention relates to a cylindrical pipe connecting device for integrally connecting two cylindrical pipes in communication.

이를 좀 더 상세히 설명하면, 원통형으로 형성된 연결관본체의 양단에 형성된 파이프접속관에 오링을 선단에 개입시켜 원통형 파이프를 각각 삽입하고, 원통형 파이프가 삽입된 각 파이프접속관에 결속너트를 각각 나사 결합하여 원통형 파이프를 밀폐되게 억류시키되, 원통형 파이프가 삽입된 각 파이프접속관의 내부에는 압착링과 고정수밀쐐기를 차례로 장전하고 결속너트를 나사 결합하여 원통형 파이프으 억류능력과 밀폐능력을 가일층 강화시킬 수 있도록 개선된 원통형 파이프 접속연결장치를 제공하려는 것이다.
To explain this in more detail, the cylindrical pipes are formed at both ends of the pipe connecting pipes formed at both ends of the cylindrical connecting pipe body by inserting the cylindrical pipes respectively, and screwing the binding nuts to each of the pipe connecting pipes into which the cylindrical pipes are inserted. The cylindrical pipes are to be kept in a sealed state, but each of the pipe connection pipes into which the cylindrical pipes are inserted can be loaded with a pressing ring and a fixed watertight wedge in turn, and the binding nut can be screwed together to further strengthen the detaining capacity and sealing capacity of the cylindrical pipe. It is an object of the present invention to provide an improved cylindrical pipe connecting device.

원통형의 형상으로 형성되는 파이프(관)는 통상적으로 합성수지 또는 금속(철재)으로 제조되며, 상수도관과 하수관 및 가스관 등 각종 유체 또는 가스를 이송시키는데 주로 사용된다.Pipes (pipes) formed in a cylindrical shape are usually made of synthetic resin or metal (iron), and are mainly used to transfer various fluids or gases such as water supply pipes, sewage pipes, and gas pipes.

상기 원통형 파이프는 소정의 길이로 성형 제조되며, 원통형 파이프는 이음관(커플링)과 같은 각종 연결장치를 이용하여 길게 연결하면서 설치하게 된다.The cylindrical pipe is molded and manufactured to a predetermined length, and the cylindrical pipe is installed while being connected for a long time using various connecting devices such as a joint pipe (coupling).

연결(이음)장치는 연결 방법과 구성에 따라 여러 가지가 제안되어 있으며, 본 발명과 유사한 종래의 연결장치로서는, 국내의 실용신안등록 제20-28520호와 실용신안등록 제20-322158호 및 공개특허 공개번호 제10-2007-79965호 등이 제안되어 있다.Various connection (joint) devices have been proposed according to the connection method and configuration, and as a conventional connection device similar to the present invention, Utility Model Registration No. 20-28520 and Utility Model Registration No. 20-322158 in Korea Patent Publication No. 10-2007-79965 and the like have been proposed.

실용신안등록 제20-28520호의 파이프 연결장치는, 원통형으로 형성된 연결관의 양단에서 고무링을 삽입하여 장전하고 단부에는 고무패킹ㆍ링ㆍ플랜지패킹을 차례로 장전하여 파이프를 삽입하며, 각 파이프에 끼워지는 연결관너트를 연결관의 양단에 나사 결합하여 파이프를 억류시키도록 된 것이다.Utility model registration No. 20-28520 pipe connection device is inserted by inserting rubber rings at both ends of connecting pipe formed in a cylindrical shape, and inserting pipes by loading rubber packing, ring, and flange packing in order at each end. The bearing nut is screwed into both ends of the connector to detain the pipe.

실용신안등록 제20-322158호의 압륜을 갖는 오수관 연결구조는, 연결관의 각 단부에는 파이프(이음관)의 선단에 패킹을 끼워 삽입시키고, 파이프(이음관)의 외측에 압륜과 너트를 끼워 압륜을 단부의 내측에 장전하고 너트를 단부에 나사 결합하여 파이프(이음관)을 억류시키도록 된 것으로, 특히 상기 압륜은 관체의 상단에 탄성편을 일정한 간격으로 형성하되 각 탄성편의 외면 상단부에는 외측의 1단경사면과 내측의 2단경사면을 돌출되게 형성하여 연결관의 단면이 2단경사면에 의해 받쳐지고 압륜이 1단경사면에 받쳐지도록 된 것이다.The sewage pipe connection structure having a pressure ring of Utility Model Registration No. 20-322158 is provided with a packing at the end of a pipe (joint pipe) at each end of the connection pipe, and a pressure wheel and a nut are fitted at the outside of the pipe (joint pipe). To the inside of the end and screwed the nut to the end to detain the pipe (joint pipe), in particular the pressure ring is formed at regular intervals of the elastic piece on the upper end of the tubular body of the outer surface of the upper end of each elastic piece The first stepped slope and the inner second stepped slope are formed to protrude so that the cross section of the connecting pipe is supported by the second stepped slope and the pressure ring is supported by the first stepped slope.

공개특허 공개번호 제10-2007-79965호의 삽입식 이중수밀 이음관은, 양단에서 파이프가 삽입되는 이음관 본체의 내주면 중간에 걸림턱을 형성하여 삽입되는 파이프의 삽입을 정지시키고, 상기 몸체의 양쪽단부에는 패킹을 삽입하여 삽입되는 파이프의 외면을 밀페시키며, 단면에는 오링을 구비하여 와샤와 스톱퍼에 의해 억류시킨 상태에서 너트를 나사 결합하되, 너트를 나사 결합하면 와샤와 스톱퍼가 오링을 내측으로 밀어 밀폐시키며, 너트와 나사산부의 내측에 형성된 돌부와의 사이에는 인디케이터(오링)를 끼워준 것이다.Insertion type double watertight joint tube of Korean Patent Application Laid-Open No. 10-2007-79965 stops the insertion of the inserted pipe by forming a locking jaw in the middle of the inner circumferential surface of the joint pipe body into which the pipe is inserted at both ends, and stops the insertion of the pipe. At the end, the outer surface of the pipe to be inserted by inserting the seal is sealed and the cross section is provided with an O-ring, and the nut is screwed in the state of being detained by the washer and the stopper.If the nut is screwed, the washer and the stopper push the O-ring inward. It seals and an indicator (O-ring) is inserted between the nut and the protrusion formed inside the threaded portion.

그러나 상기와 같은 종래의 파이프 연결장치(연결구조, 이음관)는, 연결관(이음관 본체)의 단부에 삽입된 오링 또는 패킹이 삽입되는 파이프의 외면과 접촉하여 밀폐시키도록 되어 있으므로 수밀 능력이 현저히 떨어진다.However, the conventional pipe connecting device (connecting structure, joint pipe) as described above is sealed in contact with the outer surface of the pipe into which the O-ring or packing inserted at the end of the connecting pipe (joint pipe main body) is sealed. Significantly falls

또, 너트를 나사 결합시키면 압륜이 약간 전진하면서 패킹을 밀어 선단의 패킹을 압축하거나(실용신안등록 제20-322158호), 결합되는 너트에 의해 고무패킹ㆍ링ㆍ플랜지패킹이 압축되면서 연결관(이음관 본체)의 단부에서 파이프를 지지 및 밀폐시키거나(실용신안등록 제20-28520호), 너트를 나사 결합하면 와샤와 스톱퍼가 오링을 내측으로 밀어 연결관(이음관 본체)의 단부에서 파이프를 지지 및 밀폐시키므로, 삽입 연결되는 파이프를 견실하게 억류 지지할 수 없다.
In addition, when the nut is screwed in, the pressure ring advances slightly to push the packing to compress the packing at the tip (Utility Model Registration No. 20-322158), or the rubber packing, ring, and flange packing are compressed by the coupling nut, Support and seal the pipe at the end of the joint pipe body (Utility Model Registration No. 20-28520), or screw the nut, and the washer and the stopper push the O-ring inward to prevent the pipe from the end of the pipe (joint pipe body). Since it is supported and sealed, the pipe connected to the insert cannot be reliably detained.
