따라서, 본 발명의 목적은 주철관의 어느 한 단부에 오목홈이 형성되고, 상기 주철관의 오목홈에 결합링이 끼워진 후 용접되고, 상기 주철관의 단부에 플랜지 소켓이 끼워진 후, 상기 결합링과 플랜지 소켓이 체결볼트에 의해 결합되므로서, 작업현장에서 주철관에 플랜지 소켓을 끼우기 편리한 주철관 연결용 플랜지 소켓 어셈블리를 제공하는 것이다.Therefore, an object of the present invention is a concave groove is formed at one end of the cast iron pipe, the coupling ring is inserted into the concave groove of the cast iron pipe and welded, the flange socket is fitted to the end of the cast iron pipe, the coupling ring and the flange socket The coupling bolt is coupled to provide a flange socket assembly for connecting a cast iron pipe, which is easy to fit the flange socket to the cast iron pipe in the workplace.

상기와 같은 목적을 달성하기 위한 본 발명의 바람직한 실시예를 도면을 참 조하여 상세하게 설명하기로 한다.A preferred embodiment of the present invention for achieving the above object will be described in detail with reference to the drawings.

도 1 및 도 2를 참조하면, 본 발명에 따른 주철관 연결용 플랜지 소켓 어셈블리는 주철관(10)의 어느 한 단부에 오목홈(12)이 형성되고, 상기 주철관(10)의 오목홈(12)에 결합링(20)이 끼워진 후 용접되고, 상기 주철관(10)의 단부에 플랜지 소켓(30)이 끼워진 후, 상기 결합링(20)과 플랜지 소켓(30)이 체결볼트(50)에 의해 결합된다.1 and 2, a flange socket assembly for connecting a cast iron pipe according to the present invention has a concave groove 12 formed at one end of a cast iron pipe 10, and a concave groove 12 of the cast iron pipe 10. After the coupling ring 20 is inserted and welded, the flange socket 30 is fitted to the end of the cast iron pipe 10, and the coupling ring 20 and the flange socket 30 are coupled by the fastening bolt 50. .

상기 결합링(20)에는 절개부(22)가 형성되고, 외주면에 반원형상을 가진 다수개의 플랜지부(24)가 형성되고, 상기 플랜지부(24)에 체결구멍(26)이 각각 형성된다.The coupling ring 20 is formed with a cutout 22, a plurality of flanges 24 having a semicircular shape are formed on the outer circumferential surface thereof, and fastening holes 26 are formed in the flanges 24, respectively.

이것에 의해, 상기 절개부(22)를 벌려 결합링(20)을 주철관(10)의 오목홈(12)에 끼울 수 있고, 절개부(22)의 양단을 밀착시킨 후 용접하므로서, 상기 주철관(10)의 오목홈(12)에 결합링(20)을 고정할 수 있다. 더 나아가 주철관(10)의 오목홈(12)에 결합링(20)을 고정한 후, 결합링(20)의 둘레를 용접하므로서 결합링(20)과 주철관(10)의 결합을 보강할 수 있다.As a result, the cutting portion 22 can be opened so that the coupling ring 20 can be inserted into the concave groove 12 of the cast iron tube 10, and the both ends of the cutting portion 22 are brought into close contact with each other and welded. The coupling ring 20 may be fixed to the concave groove 12 of the 10. Furthermore, after fixing the coupling ring 20 in the concave groove 12 of the cast iron pipe 10, by welding the circumference of the coupling ring 20 can be reinforced the coupling of the coupling ring 20 and the cast iron pipe (10).

상기 플랜지 소켓(30)은 중공부(32)가 형성된 원통부(34)의 외주면에 제 1 플랜지부(36)가 일체로 형성되고, 상기 제 1 플랜지부(36)에 다수개의 결합구멍(38)이 형성되고, 상기 원통부(34)의 내주면 선단에 걸림턱(40 : 도 2 참조)이 형성되고, 상기 걸림턱(40)에 수밀을 위해 패킹(42)이 장착되고, 상기 원통부(34)의 외주면에 결합링(20)의 플랜지부(24)에 대응되도록 반원형상의 제 2 플랜지부(44)가 형성된다.The flange socket 30 has a first flange portion 36 integrally formed on the outer circumferential surface of the cylindrical portion 34 in which the hollow portion 32 is formed, and a plurality of coupling holes 38 in the first flange portion 36. ) Is formed, a locking jaw 40 (see FIG. 2) is formed at the tip of the inner circumferential surface of the cylindrical portion 34, a packing 42 is mounted on the locking jaw 40 for watertightness, and the cylindrical portion ( The semicircular second flange portion 44 is formed on the outer circumferential surface of the 34 to correspond to the flange portion 24 of the coupling ring 20.

상기와 같이 구성된 본 발명에 따른 주철관용 플랜지 소켓 어셈블리는 결합링(20)을 주철관(10)의 오목홈(12)에 끼워 용접 방식으로 고정한 후, 주철관(10)의 단부에 플랜지 소켓(30)을 끼우고, 상기 결합링(20)과 플랜지 소켓(30)을 체결볼트(50)로 결합시킨다. 상기와 같이 결합링(20)과 플랜지 소켓(30)이 체결볼트(50)에 의해 결합될 때, 플랜지 소켓(30)이 체결볼트(50)의 체결력에 의해 화살표(48) 방향으로 이동되어, 플랜진 소켓(30)에 배치된 패킹(42)에 주철관(10)의 선단과 플랜지 소켓930)의 걸림턱(40)이 완전 압착되므로서, 플랜지 소켓(30)과 주철관(10) 사이에 틈새가 발생하지 않게 누수를 방지할 수 있게 된다.The flange socket assembly for cast iron pipe according to the present invention configured as described above is fixed to the concave groove 12 of the cast iron pipe 10 by a welding method, the flange socket 30 to the end of the cast iron pipe 10 Insert the coupling ring 20 and the flange socket 30 is coupled to the fastening bolt (50). When the coupling ring 20 and the flange socket 30 is coupled by the fastening bolt 50 as described above, the flange socket 30 is moved in the direction of the arrow 48 by the fastening force of the fastening bolt 50, Since the front end of the cast iron pipe 10 and the locking jaw 40 of the flange socket 930 are completely compressed to the packing 42 disposed on the flanged socket 30, a gap is formed between the flange socket 30 and the cast iron pipe 10. It is possible to prevent the leakage so that does not occur.

도 3을 참조하면, 상기와 같이 주철관의 단부에 장착된 본 발명에 따른 주철관 연결용 플랜지 소켓 어셈블리는 플랜지 소켓(30)의 제 1 플랜지부(36)와 연결되는 반대편 주철관(60)의 플랜지부(62)가 볼트(70)와 너트(72)에 의해 연결되므로서, 주철관(10)과 주철관(60)이 연결된다. 이때, 플랜지 소켓(30)과 주철관(60)의 플랜지부(62) 사이에 수밀을 위해 복수개의 패킹(64)이 장착될 수 있다.3, the flange socket assembly for connecting cast iron pipe according to the present invention mounted on the end of the cast iron pipe as described above, the flange portion of the opposite cast iron pipe 60 is connected to the first flange portion 36 of the flange socket 30 As the 62 is connected by the bolt 70 and the nut 72, the cast iron pipe 10 and the cast iron pipe 60 are connected. At this time, a plurality of packings 64 may be mounted between the flange socket 30 and the flange portion 62 of the cast iron pipe 60 for watertightness.

위에서 설명한 바와같이, 본 발명에 따른 주철관 연결용 플랜지 소켓 어셈블리는 작업현장에서 누수가 발생하지 않으면서도 주철관에 플랜지 소켓을 끼워 고정하기 편리한 효과가 있다.As described above, the flange socket assembly for the cast iron pipe connection according to the present invention has a convenient effect of fitting the flange socket to the cast iron pipe without leaking in the workplace.
