Description

Pipe Joint Coupling

본 발명은 배관을 상호 연결시키는 배관이음형 커플링에 관한 것으로 배관의 이음부분을 삽입하는 선단부에 결속링을 인출할수 있는 소켓형 커플링을 대체시켜 관이음의 조립을 보다 용이하게 한 것이다.The present invention relates to a pipe joint coupling for interconnecting pipes, and to facilitate the assembly of pipe joints by replacing the socket-type coupling that can pull out the binding ring at the distal end of the pipe insert.

종래의 배관이음용 커플링은 주로 상하 반원형으로 분리된 상,하커플링을 볼트, 너트로서 조립하였으므로 조립시 양쪽 배관의 수평정확도 등으로 조립하기가 까다롭고 작업시간도 많이 소요되었다.In the conventional pipe joint coupling, the upper and lower couplings separated into upper and lower semicircles are assembled as bolts and nuts, so it is difficult to assemble with horizontal accuracy of both pipes, and it takes a lot of work time.

본 발명에서는 이와같은 결점들을 해결하기 위하여 상하로 분리된 상,하 커플링대신에 원통형 소켓을 이용하여 소켓중간부의 내주연양쪽에 삽입홈을 형성시켜 패킹을 끼워 넣어서 삽입되는 배관의 이음부분을 밀폐시키고 이음부분이 삽입되는 소켓의 각 선단부에는 상하로 서로 대칭이 되게 내부통로의 일측절반을 관통한 인출통로와 타측내부 절반인 결속통로 그리고 내부통로 중간지점의 외측끝단에 걸림턱을 형성시켜서 배관연결시에는 결속링으로 양쪽배관의 외향쪽으로 삽입하여 이음부분에 형성시킨 수개의 돌기를 내향쪽으로 걸어서 소켓양쪽의 선단부 인출통로를 통해 내부통로에서 타측 결속통로로 회전시킨후 약간 외향쪽으로 전진시켜 결속링의 상,하부 돌출단으로 내부통로 중간지점에 돌출시킨 걸림턱에 걸리도록 고정시켜서 간편하게 조립할 수가 있는 것으로 도면에 의거 상세히 설명하면 다음과 같다.In the present invention, in order to solve the drawbacks, instead of the upper and lower couplings separated by upper and lower couplings, an insertion groove is formed on both inner circumferential edges of the middle portion of the socket by using a cylindrical socket to insert the joints of the pipe to be inserted. Each end of the socket, which is sealed and the joint part is inserted, has a drawout passage through one side half of the inner passage so as to be symmetrical with each other up and down, a binding passage which is the other inner half, and a locking jaw at the outer end of the middle point of the inner passage. In case of connection, insert the outwards of both pipes with the binding ring and turn the inwards of several projections formed in the joint part, and rotate it from the inner passage to the other binding passage through the distal end passages on both sides of the socket, and then move forward slightly outward. The upper and lower protrusions of the upper and lower protrusions can be easily fixed to be caught by the locking projection protruding from the middle point of the inner passage. If the crab can be assembled in detail according to the drawings as follows.
