관체 연결 장치Tubular coupling device
본 발명은 관체 연결 장치에 관한 것으로서, 보다 구체적으로는 용접방식을 사용하지 않고 배관간의 연결을 간단한 작업을 통해 수행하게 하면서도 제작이 용이한 관체 연결 장치에 관한 것이다.The present invention relates to a pipe connecting device, and more particularly, to a pipe connecting device that is easy to manufacture while performing a connection between pipes without using a welding method through a simple operation.

If the connection is made through the welding method, it is essential to secure a working space because the welding part must be made along the outer circumference of the pipe, and the pressure ring is interposed between the pipes in the future when the defect is repaired as the pipe is connected by welding through the pressure wheel. Or, if it needs to be reinstalled, there is a problem that the separation and reinstallation of the pressure wheel between the pipes is very difficult, there is a problem in that expensive pipe joints should be provided separately when connecting pipes of different sizes according to the flange, welding, and the like.

참고로 상기 배관삽입부재(100)의 관통홀(111)에 형성된 수평부(111-1)는 연결플랜지(110) 및 배관(10) 사이의 공간에 고무패킹(200)이 끼움되도록 하여 고정력을 향상시키기 위한 것이고, 경사부(111-2)는 언급된 바와 같이 연결플랜지(110) 및 배관(10) 사이에 고무패킹(200) 및 배관고정부재(300)가 삽입되도록 하기 위한 것이다.For reference, the horizontal portion 111-1 formed in the through hole 111 of the pipe inserting member 100 allows the rubber packing 200 to be fitted into a space between the connection flange 110 and the pipe 10 so as to provide a fixing force. In order to improve, the inclined portion 111-2 is to allow the rubber packing 200 and the pipe fixing member 300 to be inserted between the connection flange 110 and the pipe 10 as mentioned.
상기 고무패킹(200)은 일측 및 타측이 각각 배관삽입부재(100)의 관통홀(111) 내측면과 배관삽입부재(100)에 삽입된 배관(10) 외측면을 따라 밀착되고, 연결플랜지(110)의 외측으로 돌출되는 부분이 배관(10) 끝단면을 따라 밀착되어 연결플랜지(110)와 볼팅결합되는 플랜지(20)를 구비한 관체에 의해 가압되면서 배관삽입부재(100)와 플랜지(20) 사이에 수밀성을 보장하게 되고, 연결플랜지(110)와 플랜지(20)의 볼팅결합 과정에서 배관삽입부재(100)가 배관(10) 외측을 향하여 이동됨에 따라 결과적으로 배관고정부재(300)가 배관(10) 및 관체부(120) 사이에 억지끼움되도록 함으로써 결과적으로 배관(10)과 플랜지(20)를 구비한 관체를 견고히 연결시키게 된다.One side and the other side of the rubber packing 200 is in close contact with the inner surface of the through hole 111 and the outer surface of the pipe 10 inserted into the pipe insertion member 100, respectively, and the connecting flange ( The portion protruding outward from the 110 is tightly pressed along the end surface of the pipe 10 and is pressurized by a pipe body having a flange 20 bolted to the connection flange 110 to be connected to the pipe insertion member 100 and the flange 20. ) To ensure watertightness, and as the pipe insertion member 100 is moved toward the outside of the pipe 10 during the bolting coupling process of the connection flange 110 and the flange 20, the pipe fixing member 300 is consequently moved. By interposing between the pipe 10 and the pipe portion 120, as a result, the pipe 10 and the pipe body having the flange 20 are firmly connected.
상기 배관고정부재(300)는 배관삽입부재(100) 및 배관(10) 사이에 배치되는 고무패킹(200)에 일체로 매설되는 고정부(310)와, 고정부(310)로부터 직경이 감소되는 관체부(120)측으로 연장되고 일측 및 타측이 각각 배관삽입부재(100)의 내측면과 배관삽입부재(100)에 삽입된 배관(10) 외측면을 따라 밀착되며 배관(10)과 밀착되는 면에 톱니가 구비된 끼움부(320)로 이루어져 고무패킹(200) 둘레를 따라 복수개가 상호간에 일정간격 이격되도록 배치된다.The pipe fixing member 300 is a fixed portion 310 is integrally embedded in the rubber packing 200 disposed between the pipe insertion member 100 and the pipe 10, and the diameter is reduced from the fixed portion 310 Surface extending to the pipe portion 120 side and one side and the other side is in close contact with the inner surface of the pipe inserting member 100 and the outer surface of the pipe 10 inserted into the pipe inserting member 100 and are in close contact with the pipe 10. A plurality of teeth formed along the circumference of the fitting part 320 is disposed to be spaced apart from each other by a predetermined interval along the circumference of the rubber packing 200.
이와 같은 상기 배관고정부재(300)에 의하면, 배관(10)과 플랜지(20)를 구비한 관체간의 볼팅 결합시에 끼움부(320)가 관체부(120)측으로 진행됨에 따라 끼움부의 톱니가 배관(10)에 밀착되어 배관삽입부재(100)가 배관(10)으로부터 이탈되지 않게 되는 한편, 고무패킹(200)에 배관고정부재(300)가 고정되어 있는 이유로 고무패킹(200)의 탄성력에 의해 복수개의 배관고정부재(300) 각각이 유동적이기 때문에 배관(10)과 관체부(120) 사이 공간으로 쉽게 삽입될 수 있으면서도 관체부(120)측으로 진행 될수록 보다 견고히 배관(10)에 밀착될 수 있다.According to the pipe fixing member 300 as described above, when the fitting portion 320 advances to the pipe portion 120 side during bolting coupling between the pipe 10 and the pipe body provided with the flange 20, the teeth of the fitting portion are piped. By the elastic force of the rubber packing 200 is in close contact with the 10 so that the pipe inserting member 100 is not separated from the pipe 10 and the pipe fixing member 300 is fixed to the rubber packing 200. Since each of the plurality of pipe fixing members 300 is fluid, the pipe fixing member 300 may be easily inserted into the space between the pipe 10 and the pipe body 120, but may be more tightly adhered to the pipe 10 as the pipe body 120 is moved toward the pipe body 120. .
더욱 상세하게는, 상기 배관삽입부재(100)가 배관(10) 외측으로 이동할 시에 경사부(111-2) 및 관체부(120)에 의해 배관(10)과의 이격거리가 좁아지는 공간으로 배관고정부재(300)의 끼움부(320)가 억지끼움되면서 톱니가 배관(10) 외측면에 견고히 밀착됨에 따라 배관삽입부재(100)가 배관(10)에 고정된 상태를 유지하게 되며, 고무패킹(200)에 일정간격 이격 고정됨으로 인해 배관고정부재(300)가 보다 용이하게 배관(10)측으로 휘어지게 할 수 있다.In more detail, when the pipe insertion member 100 moves to the outside of the pipe 10, the space between the pipe 10 and the pipe 10 is narrowed by the inclined part 111-2 and the pipe part 120. As the fitting portion 320 of the pipe fixing member 300 is tightly fitted and the teeth are tightly adhered to the outer surface of the pipe 10, the pipe insertion member 100 is maintained in a fixed state to the pipe 10, and rubber Due to fixed intervals fixed to the packing 200, the pipe fixing member 300 can be more easily bent toward the pipe 10 side.
또한 주철관과 같이 재질 및 제작과정상의 이유로 외주면에 굴곡이 심하게 형성되어 있는 관체의 경우에도 배관고정부재(300)가 유동적임에 따라 배관(10)에 배관고정부재(300)가 손쉽게 밀착될 수 있다.In addition, even in the case of a pipe body formed with a bend on the outer circumferential surface due to a material and a manufacturing process, such as a cast iron pipe, the pipe fixing member 300 may be easily adhered to the pipe 10 as the pipe fixing member 300 is fluid. .
추가로 상기 배관고정부재(300)는 별도의 가공 없이 금형에 의해 사전 제작된 다음 유체상태의 고무패킹(200)을 성형할 시에 단순히 고정부(310)가 고무패킹(200)에 매설되도록 하여 고무패킹(200)과 일체화될 수 있기 때문에, 그 제작이 용이함과 동시에 고무패킹(200)에 설치하는 과정도 매우 간편하게 이루어지도록 한다.In addition, the pipe fixing member 300 is pre-manufactured by a mold without any additional processing, and then, when forming the rubber packing 200 in a fluid state, the fixing part 310 is simply buried in the rubber packing 200. Since it can be integrated with the rubber packing 200, the process is easy to manufacture and at the same time to be installed in the rubber packing 200 to be made very simple.
여기서 상기 배관고정부재(300)의 고정부(310)와 고무패킹(200)간의 결속력을 향상시키기 위해 그 고정부(310)에 통공(311)을 형성할 수도 있는데, 이 통공(311)을 구비한 배관고정부재(300)를 고무패킹(200) 성형 시 설치하게 되면, 유체상태의 고무가 통공(311)을 통과한 다음 경화됨에 따라 고정부(310)가 고무패킹(200)으로 이탈되는 현상을 방지하게 되며, 고무패킹(200)이 도 4에서와 같이 배관(10) 및 배관삽입부재(100)에 배치된 상태에서 통공(311)이 고무패킹(200)의 둘레에 따른 방향으로 형성되도록 하여 통공(311)에 충전된 고무가 가급적 고무량이 많은 부분과 연속되도록 하는 것이 바람직할 것이다.Here, the through hole 311 may be formed in the fixing part 310 to improve the binding force between the fixing part 310 of the pipe fixing member 300 and the rubber packing 200, and the through hole 311 is provided. When the pipe fixing member 300 is installed during the molding of the rubber packing 200, a phenomenon in which the fixing part 310 is separated into the rubber packing 200 as the rubber in the fluid state passes through the through hole 311 and then hardens. In the state in which the rubber packing 200 is disposed in the pipe 10 and the pipe insertion member 100 as shown in FIG. 4, the through hole 311 is formed in the direction along the circumference of the rubber packing 200. It will be desirable to allow the rubber filled in the through hole 311 to be continuous with the portion of the rubber amount as much as possible.
