* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

1 : 소켓트 3, 3' : 유니온 너트1: Socket 3, 3 ': Union nut

4, 4', 5 : 요구 6 : 스리이브 패킹4, 4 ', 5: Required 6: Live Packing

본 고안은 합성수지 파이프 연결장치에 관한 것으로 양측 파이프를 연결하는 소켓트와 유니온너트 사이에 고무재질의 슬리이브 패킹을 개재시키므로서 소켓트와 유니온너트 사이의 누수를 압축압력으로 방지함과 동시에 피연결 파이프와 슬리이브패킹 사이를 조임압력에 의하여 밀폐도를 높이고 피연력 파이프 내면에 보조금속관을 끼워 넣어 복원력을 높이고져 한 것이다.The present invention relates to a synthetic resin pipe connecting device, which prevents water leakage between the socket nut and the union nut by compressive pressure while interposing the rubber sleeve seal packing between the socket nut and the union nut connecting both pipes. The sealing force is increased between the pipe and the sleeve packing by the tightening pressure, and the restoring force is increased by inserting the auxiliary metal pipe into the inner surface of the force pipe.

종전의 파이프 연결장치는 여러 종류가 있겠으나 특히 합성수지 파이프의 연결장치는 파이프에 플랜지를 구성하여 양측 플랜지를 유니온너트로 직결하므로서 연결부의 누수방지는 용이한 것이나 이들 플랜지를 구성한 합성수지 파이프는 양산성이 되지 못하여 가격이 높아지는 결함을 갖게되는 것이고, 직관 합성수지 파이프의 경우에는 금속관 파이프의 연결에서 이용되는 것과같이 소켓트 양측에 0링을 개재하여 연결하는 방식으로서는 합성수지 파이프의 응력변화에 따른 연결부의 변형에 의하여 누수율이 높아 잦은 보수작업이 필요하여지는 문제점이 있는 것이었다.There are many kinds of conventional pipe connecting devices, but in particular, the connecting pipe of synthetic resin pipes has flanges on the pipes so that both flanges are connected directly with union nuts, so it is easy to prevent leakage of the connecting parts. In the case of a straight pipe synthetic pipe, as in the case of the connection of a metal pipe, a connection between the sockets through zero rings is used to deform the connection part due to the stress variation of the plastic pipe. As a result, the leak rate was high, requiring frequent maintenance work.

본 고안은 상기에서와 같은 문제점을 감안하여 합성수지 파이프 연결부에 압축압력과 조임압력으로 밀페도를 높이고 복원력을 보완시켜 누수예방이 완벽하고 시설작업성도 편리한 연결장치를 제공한 것으로 이를 첨부도면에 의하여 상술하면 다음과 같다.The present invention, in view of the above problems, to provide a connection device to prevent the leakage and perfect facility workability by increasing the sealing degree and the restoring force by compressing pressure and tightening pressure in the synthetic pipe connecting portion, as described above by the accompanying drawings Is as follows.

본 고안은 제1도에서와 같이 합성수지의 소켓트(1)의 양측에 서로 반대방향으로된 유니온나사(2)(2')를 구성하고 이에 합성수지의 유니온너트(3)(3')를 돌려끼워 결합하게 된 것에 있어서 소켓트(1)의 양측 내경부에 경사면을 갖은 요구(4)(4')를 형성하고 유니온너트(3)(3')에도 경사면을 갖은 요구(5)를 각각 형성하여 양단면에 경사면(6a)이 형성되고, 동체부(6b)가 길게 형성된 고무재질의 슬리이브패킹(6)을 상기의 (4)(4')(5)사이에 개재시키며 보조금속관(7)을 피연결 파이프 내경에 끼우도록 구성 된 것으로 보조금속관에는 절결부(7')를 형성하였다.The present invention constitutes union screws (2) (2 ') opposite to each other on both sides of the socket (1) of the synthetic resin, as shown in Figure 1 and turn the union nut (3) (3') of the synthetic resin In this case, requests (4) and (4 ') having inclined surfaces are formed in both inner diameter portions of the socket (1), and requests (5) having inclined surfaces are also formed in the union nuts (3) and 3', respectively. And the inclined surface 6a on both end surfaces thereof, and the rubber sleeve 6 of which the body portion 6b is formed is interposed between the above (4) (4 ') (5) and the auxiliary metal pipe (7). ) Is formed to fit the inner diameter of the pipe to be connected, and a notch 7 'is formed in the auxiliary metal pipe.

이와같이 된 본 고안은 제2도에서와 같이 직선이음용의 피연결 합성수지 파이프 (8)(8') 내경부에는 보조금속관(7)을 끼우고, 외경부에는 유니온너트(3)(3')와 고무패킹 (6)을 각각 끼운후에 합성수지 파이프(8)(8')의 끝을 양측에서 소켓트(1)내에 끼우고 소켓트(1)양측에 있는 유니온너트(3)(3')를 돌려 결합하면 되는 것이고, 분리할때에는 위와 반대순서로 분리할 수 있는 것이다.The present invention has a secondary metal pipe (7) in the inner diameter portion of the connected synthetic resin pipe (8) (8 ') for straight joint as shown in Fig. 2, and a union nut (3) (3') in the outer diameter portion. And rubber packing (6), respectively, insert the ends of the synthetic resin pipes (8) and (8 ') into the socket (1) from both sides and insert the union nuts (3) (3') on both sides of the socket (1). It can be combined by turning, and when separating, they can be separated in the reverse order.

그리고, 합성수지 파이프(8)(8')내에 보조금속관(7)을 끼울때 절결부(7')가 있어 끼움작업이 용이한 것이다.When the auxiliary metal pipe 7 is inserted into the synthetic resin pipes 8 and 8 ', there is a notch 7' to facilitate the fitting operation.

상기에서와 같이 소켓트(1)와 유니온너트(3)(3')의 요구(4)(4')(5)사이에 개재되는 슬리이브패킹(6)의 동체부(6b)를 길게 형성하고 양단부에 경사면(6a)을 형성하여 접속면을 크게하므로서 밀폐도를 높이고 더욱 유니온 너트(3)(3')를 조임에 따른 압측압력이 슬리이브패킹(6)의 양단 경사면(6a)에 가하여짐과 동시에 동체부(6b)의 수축에 따라 패킹(6)의 내경이 좁아지면서 밀폐도가 더욱 높아지므로서 누수방지효과가 완벽하여지며 또한 직선이음 기능도 발휘할 수 있는 것이다.As described above, the body portion 6b of the sleeve packing 6 interposed between the socket 4 and the requests 4, 4 ', 5 of the union nut 3, 3' is formed long. And the inclined surface 6a is formed at both ends to increase the connection surface, thereby increasing the sealing degree, and the pressing pressure caused by tightening the union nuts 3 and 3 'is applied to the inclined surface 6a at both ends of the sleeve packing 6 As the inner diameter of the packing 6 becomes narrower as the body portion 6b shrinks at the same time as the load, the sealing is further increased, thereby preventing leakage and perfecting the linear joint function.

그리고 슬리이브패킹(6)의 내경면에 종횡요철면(6')을 형성하여 밀착효과를 높일수도 있는 것이다.The longitudinal effect of the sleeve packing 6 may be formed on the inner and outer concave-convex surface 6 'to increase the adhesion effect.

더욱이 보조금속관(7)을 연결하고자 하는 합성수지 파이프(8)(8')의 내경부에 삽입하므로서 복원력을 높이고, 연결시 슬리이브패킹(6)의 압축으로 인한 합성수지 파이프(8)(8')의 우구러짐이나 손상을 방지하여 연결부분에서의 완벽한 밀봉효과를 나타내게되는 것이다.Furthermore, the restoring force is increased by inserting the auxiliary metal pipe 7 into the inner diameter of the synthetic resin pipe 8 and 8 ', and the synthetic pipe 8 and 8' due to the compression of the sleeve packing 6 when connected. It prevents dents and damages and shows perfect sealing effect at the connection part.
