Description

관 이음장치{pipe connecting device}Pipe connecting device

본 발명은 금속 또는 합성수지로 구성된 두 개의 파이프나, 파이프와 이음관을 상호 연결하는 관 이음장치에 관한 것으로서, 보다 구체적으로는 플랜지를 별도 부착하지 않고도 수밀성과 아울러 견고한 결합성을 제공할 수 있는 관 이음장치를 제공코자 하는 것이다.The present invention relates to two pipes made of metal or synthetic resin, or a pipe joint device for interconnecting pipes and pipes, and more specifically, a pipe that can provide watertightness and robust bonding without attaching a flange separately. It is to provide a joint device.

두 개의 파이프를 상호 연결하는 일반적인 방법으로는 두 파이프의 접속부를 용접하는 방법과, 파이프의 단부에 플랜지를 형성하여 패킹을 사이에 두고 양측 플랜지를 밀착하여 볼트와 너트로 고정하는 방법이 제공되고 있다.As a general method of interconnecting two pipes, there is provided a method of welding the joints of two pipes and a method of forming a flange at the end of the pipe and fixing the two flanges in close contact with the packing between the two pipes. .

그러나 상기한 방법들의 경우 용접을 반드시 행해야 하는데, 용접의 경우 전문인력 또는 고가의 용접 전용장비를 필요로 하므로 생산성이 떨어지고 그로 인해 제조비용이 상승하게 되는 문제점이 있었다.However, in the case of the above methods, the welding must be performed, but in the case of welding, a professional manpower or expensive welding-only equipment is required, and thus there is a problem in that productivity decreases and thus manufacturing cost increases.

또한 용접 부분은 부식 등으로 제품의 수명을 단축시키는 원인이 되기도 한다.In addition, the welded part may cause corrosion of the product and shorten the life of the product.

한편 대한민국 특허공보 1997-0005209호(1997.04.14.)의 관 이음쇠가 제안된 바 있으며, 이는 파이프의 단부에 나팔상의 확관부와, 양측 파이프에 형성된 확관부 사이에 배치되며 확관부의 내주 경사면과 접하는 경사면 및 확관부의 단부를 수용하는 단턱부가 일체로 형성된 패킹과, 상기 확관부와 패킹을 수용하는 오목부가 형성되는 클램프를 포함하는 구성으로 이루어져 있다.Meanwhile, a pipe fitting of Korean Patent Publication No. 1997-0005209 (1997.04.14.) Has been proposed, which is disposed between a trumpet-shaped expansion pipe at an end of a pipe and an expansion pipe formed at both pipes, It consists of a configuration including a packing formed integrally with the stepped portion accommodating the inclined surface and the end portion of the expansion pipe portion, and a clamp formed with a recess for accommodating the expansion pipe portion and the packing.

이러한 구성의 선행기술은 파이프의 단부에 플랜지를 용접하는 등의 작업 없이도 파이프를 연결할 수 있는 이점이 있으나, 유체압력에 의해 클램프의 벌어짐 현상이 우려되고, 또한 지반침하 등으로 양측 파이프에 전단력이 생길 때 파이프 및 패킹이 서로 이완되어 누수의 염려가 있는 등의 여러 문제점이 있었다.
The prior art of such a configuration has the advantage that the pipe can be connected without the work, such as welding the flange to the end of the pipe, but the pliability of the clamp is feared due to the fluid pressure, and the shear force is generated on both pipes due to ground subsidence When the pipe and the packing is relaxed with each other there is a number of problems, such as the possibility of leakage.

KR 10-1997-0005209 B1 1997.04.14.KR 10-1997-0005209 B1 1997.04.14.
