본 고안은 한쌍의 파이프를 연결 접속시킴에 있어서 각 파이프의 선단을 암카플링(Female-Coupling)속에 삽입한 후 파이프와 암카플링을 체결 키이(Installing key)로서 연결고정시키는 종래의 파이프 죠인트장치를 개량하여 누수를 방지함으로서 고압송수관용으로 사용될 수 있고 또한 설치비를 절감시킬 수 있도록 하기 위한 것이다.The present invention improves the conventional pipe joint device for connecting a pair of pipes by inserting the ends of each pipe into a female coupling and then connecting and fixing the pipe and the female coupling as a mounting key. It can be used for high pressure water pipes to prevent leakage and to reduce the installation cost.
종래의 파이프 죠인트 장치는 제5도에 도시한 바와 같이 접속시킬 한쌍의 파이프(1)(1')의 접속부선단 외주면에 오링(O-Ring)(2)을 감합시키고 키이홈(3)을 형성하여 한 쌍의 파이프(1)(1')의 각 접속선단을 내주면에 키이홈(3')이 형성된 카플링관(4) 속에 삽입하고 파이프와 카플링관의 키이홈(3)(3') 사이에 체결키이(5)를 삽입하여 연결 접속하는 것이었는 바, 이 경우에 접속된 한 쌍의 파이프(1)(1') 중 일방 또는 쌍방이 직선 연결상태에서 벗어나 기울게 되는 경우에는 오링(2)과 카플링관(4)의 압접상태가 일측부에서 해이해지고 이로 인하여 압력수를 송수하는 경우에는 누수현상이 발생하게 되는 것이었으므로 이와같은 파이프의 기울기를 방지하기 위하여는 한 쌍의 파이프(1)(1')를 직선상으로 유지시키기 위한 장치로서 밸러스트브록(Ballast Block)이나 파이프 앵커(Pipe Anchors) 등의 각종 고정설비를 필요로 하는 것이어서 설치비용이 많이 드는 결점이 있는 것이었다.In the conventional pipe joint apparatus, as shown in FIG. 5, an O-ring 2 is fitted to the outer circumferential surface of the connection end of the pair of pipes 1 and 1 'to be connected and a key groove 3 is formed. Insert the connecting end of each pair of pipes (1) and (1 ') into the coupling pipe (4) with the key groove (3') formed on the inner circumferential surface, and between the pipe and the key groove (3) (3 ') of the coupling pipe. In this case, when one or both of the pair of pipes (1) (1 ') connected to each other are inclined out of the linear connection state, the O-ring (2) is connected. And the coupling state of the coupling pipe 4 is loosened at one side, and when the pressure water is transmitted, leakage occurs. Therefore, in order to prevent such a slope of the pipe, a pair of pipes 1 Ballast block or pipe as a device for keeping 1 'in a straight line Various fixing facilities such as anchors (Pipe Anchors) are required, so the installation cost is high.
본 고안은 이와같은 종래의 결점을 제거하기 위하여 고안된 것으로서 특히 합성수지나 화이바그라스로 된 파이프의 연결용으로 적합하도록 구성한 것으로서 이하 도면에 따라 상세히 설명하면 다음과 같다.The present invention is designed to eliminate such a conventional defect, and in particular, it is configured to be suitable for the connection of pipes made of synthetic resin or fiber glass as described below in detail according to the drawings.
접속할 한 쌍의 파이프(1)(1')의 접속부 선단에 오링(2)이 감합하고 키이홈(3)아 형성된 합성수지재의 접속수(6)(6')를 나합하여 각 접속구(6)(6')를 내주면에 키이홈(3')이 형성된 카플링관(4)속에 삽입하고 접속구(6)(6')의 키이홈(3)과 카풀링관(4)의 키이홈(3') 사이에 체결키이(5)를 삽입하여 연결 접속하게 된 통상의 것에 있어서, 각 접속구(6)(6')의 선단부 외주벽과 후단부 외주벽에 방사상으로 돌출된 수 개의 접촉돌기(7)(7')를 형성하여 각 접촉돌기(7)(7')의 선단부가 카풀링관(4)의 내주면에 압접되도록 구성하여서 된 것이다.The O-ring 2 is fitted to the distal end of the pair of pipes 1 and 1 'to be connected, and the joints 6 and 6' of the synthetic resin material formed by the key grooves 3 are screwed together to connect each connector 6 ( 6 ') is inserted into the coupling pipe 4 formed with the key groove 3' on the inner circumferential surface, and between the key groove 3 of the connector 6 and 6 'and the key groove 3' of the carpooling tube 4 '. In the usual case in which the fastening key 5 is inserted into and connected to each other, several contact protrusions 7 and 7 projecting radially on the outer peripheral wall of the front end and the outer peripheral wall of the rear end of each connector 6, 6 '. ') Is formed so that the tip end of each contact projection (7) (7') is pressed against the inner circumferential surface of the carpooling pipe (4).
이와같이 구성된 본 고안은 카플링관(4) 속에 삽입된 접속구(6)(6')가 제3도 및 제4도에 도시한 바와 같이 방사상으로 돌출된 접촉돌기(7)(7')에 의하여 카플링관(4)의 내주벽과 균일하게 밀착되는 것이어서 외부로부터 접속된 파이프(1)(1')이 힘이 가하여 지더라도 접속구(6)(6')의 선후단부에 돌출된 접촉돌기(7)(7')와 카플링관(4)의 내면은 간격없이 긴밀하게 압접된 상태에 있는 것이므로 접속구(6)(6')가 요동되지 않고 한쌍의 파이프(1)(1')는 직선적 연결상태를 유지하게 되어 오링(2)이 의한 밀봉상태가 불변하게 계속되므로 서로 압송수시에도 누수를 방지하기 되는 것이며, 파이프(1)(1')의 요동방지를 위한 별도의 설비를 요하지 않게 되므로서 설치경비를 크게 절감할 수 있게 되는 것이다. 또한 접촉돌기(7)(7')는 접속구(6)(6')와 같이 합성수지로 성형되고 제4도에 도시된 바와 같이 그 단면이 삼각형상으로 되게 하므로서 접속구(6)(6')를 카풀링관(4) 속으로 삽입할 때 삼각형의 접촉돌기(7)(7')가 합성수지 고유의 탄성에 따라 압축되면서 용이하게 삽입될 수 있는 것이며, 분해시에도 각 접촉돌기(7)(7')와 카플링관(4)이 선접촉(綿接觸) 상태에 있는 것이어서 큰 마찰저항을 받지 않고 용이하게 분해할 수 있는 것이어서 사용상 편리한 작용효과를 나타내게 되는것이다.According to the present invention configured as described above, the couplings 6 and 6 'inserted into the coupling tube 4 are coupled by radially protruding contact protrusions 7 and 7' as shown in FIGS. 3 and 4. The contact projections 7 protruding uniformly in contact with the inner circumferential wall of the pipe 4 so that the pipes 1 and 1 'connected from the outside protrude from the front and rear ends of the connection ports 6 and 6' even when a force is applied. Since the inner surface of the 7 'and the coupling pipe 4 are in close contact with each other without any gap, the connection ports 6 and 6' are not rocked and the pair of pipes 1 and 1 ' Since the state of sealing by the O-ring (2) continues unchanged, water leakage is prevented even when water is pumped to each other, and installation cost is not required because it does not require a separate facility for preventing the fluctuation of the pipe (1) (1 '). It will be able to greatly reduce the. In addition, the contact projections 7 and 7 'are formed of synthetic resin, such as the connectors 6 and 6', and the connectors 6 and 6 'are formed by making the cross section triangular as shown in FIG. When inserted into the carpooling tube (4), the triangular contact protrusions (7) (7 ') can be easily inserted while being compressed according to the inherent elasticity of the synthetic resin, and each contact protrusion (7) (7') even when disassembled. ) And the coupling tube (4) are in a line contact (받지) state that can be easily disassembled without being subjected to large frictional resistance, thereby showing a convenient operation effect.
