Description

파이프용 수밀을 위한 연결구{A coupling pipe for waterproofing of plastic pipe}A coupling pipe for waterproofing of plastic pipes

본 발명은 파이프용 수밀을 위한 연결구에 관한 것으로, 더욱 상세하게는 하수관이나 상수도관 등의 파이프를 연결하는 원통형 링의 양쪽으로 삽입되는 고무링을 밀착하여 체결하면서 안정되고 견고하게 연결되어 파이프의 수밀을 유지할 수 있도록 하는 파이프용 수밀을 위한 연결구에 관한 것이다.The present invention relates to a connector for watertightness for pipes, and more particularly, the rubber ring is inserted into both sides of the cylindrical ring for connecting pipes, such as sewage pipes and water supply pipes, while being tightly connected and stable and firmly connected to the watertightness of the pipes. It relates to a connector for watertightness for the pipe to be able to maintain.

일반적으로 하수관이나 상수도관으로 사용하는 파이프는 금속 또는 합성수지 재질을 이용하여 성형하게 되며, 합성수지 재질로 성형하는 파이프는 다양한 구조와 기능으로 분류되지만 대체로 성형한 후 6미터 정도의 길이를 갖도록 절단한 후 지하에 매설할 때 다양한 연결방법을 이용하여 연결하게 된다.Generally, pipes used as sewage pipes or water pipes are formed using metal or synthetic resin materials. Pipes formed from synthetic resin materials are classified into various structures and functions, but are generally cut to have a length of about 6 meters after molding. When buried underground, it is connected by using various connection methods.

이러한 파이프를 연결하는 종래 기술로는 특허등록 제288133호(2001. 4. 16. 공고)가 있으며, 파이프를 맞대기 한 후 양쪽을 시트로 감아 고정한 후 시트의 내부에 설치한 메탈라스에 전원을 공급하여 메탈라스가 공급되는 전원으로 발열하면 서 시트와 파이프의 내경을 용융시켜 이들이 서로 연결 되도록 하는 것이다.The conventional technology for connecting such pipes is Patent Registration No. 288133 (August 16, 2001) .After joining the pipes together, both sides are wrapped with sheets and fixed, and then the power is supplied to the metal lath installed inside the sheets. Thus, the inner diameter of the sheet and the pipe are melted while they are generated by the power supplied by the metal lath so that they are connected to each other.

그러나 이러한 종래기술은 전원을 이용해야 하는 시트 융착법이므로 전원이 없는 곳이나 물속에서는 작업이 어렵고, 전체면이 균일하게 융착되지 않고 겹치는 부분에서 누수현상이 발생하는 결점이 있었다.However, since the prior art is a sheet fusion method that requires the use of a power source, it is difficult to work in a place without water or in the water, and the entire surface is not uniformly fused, and there is a defect in which water leakage occurs in an overlapping part.

다른 종래기술로는 특허등록번호 제768812호(2007. 9. 8. 등록)는 파이프의 선단 내경을 가공한 후 사출하여 성형한 플랜지를 나사식으로 연결하고, 플랜지를 맞대기하여 볼트와 너트로 플랜지를 서로 고정하는 방법을 사용하게 된다.As another prior art, Patent Registration No. 768812 (registered on Sep. 8, 2007) is to connect the flange molded by injection molding after processing the inner diameter of the pipe and screw the flange together to flange the bolt and nut. We will use the method of fixing the two to each other.

그러나 이러한 종래기술은 복잡한 금형으로 이루어진 플랜지를 사출하게 되므로 금형비의 소모가 발생하고, 전체면에서 등 간격으로 볼트와 너트를 조임 해야 균일한 압력으로 연결하여 누수를 방지할 수 있으나, 균일한 조임력을 제공하는 것이 매우 어렵고, 이로 인하여 누수가 발생하는 결점이 있었다.However, the conventional technology is to inject a flange made of a complex mold, so the consumption of mold cost occurs, and the bolts and nuts should be tightened at equal intervals on the entire surface to connect with a uniform pressure to prevent leakage, but even tightening force It is very difficult to provide, which has the drawback of leaking.

그리고 종래 조립식으로 결합하는 연결구는 플랜지를 이용하여 서로 고정하거나, 헤드를 이용하여 압륜으로 누르면서 고정하는 방식 및 파이프를 안으로 조임하는 방식에 의하여 오랜 시간이 지난 후 내경을 촬영하면 연결부분에서 안으로 무너져내리는 내경 방향으로의 파이프가 변형되므로 이 부분에서 누수가 발생해 연결부분의 주변에 흙이 오염되는 결점이 발생하게 되었다.And the connectors that are assembled in the conventional assembly is fixed to each other by using a flange, or by pressing with a pressure ring by using a head and a method of tightening the pipe in the way by taking a picture of the inner diameter after a long time is broken down in the connection part As the pipe in the inner diameter is deformed, a leak occurs in this area, resulting in a defect in which soil is contaminated around the connection part.

본 발명은 이러한 종래의 결점을 해소하기 위하여 안출된 것으로, 파이프가 연결되는 양쪽에서 고무링을 삽입하고 이 고무링을 밀착하면서 안정되게 연결이 이루어지며, 연결부분에서의 수밀을 유지할 수 있도록 함을 목적으로 하는 것이다.The present invention has been made to solve the above-mentioned drawbacks, inserting a rubber ring on both sides of the pipe is connected and the connection is made stable while keeping the rubber ring in close contact, it is possible to maintain the watertight at the connection portion It is for the purpose.

본 발명은 체결상태를 안정되게 유지하며, 파이프의 열팽창계수에 따른 변형에도 효과적으로 대응할 수 있도록 함을 목적으로 하는 것이다.The present invention aims to keep the fastening state stable and to effectively cope with deformation caused by the coefficient of thermal expansion of the pipe.
