Abstract

본 발명은 한쪽에 금속관을 접속하기 위한 금속접속부재가 삽입·성형되고, 다른 쪽에 합성수지관이 삽입·융착되는 합성수지관 이음매 및 접속부재가 견고하게 결합되는 관 이음매의 제조방법에 관한 것이다. 금속접속부재 부착의 합성수지관 이음매는 금속접속부재에 관축방향 및 관축과 직교하는 방향으로 공동이 형성되고, 회전을 방지하기 위한 홈붙이 노치가 형성되며, 점서의 변성 폴리에틸렌으로 금속접속부재를 피복한 후에 가교 폴리에틸렌을 사출성형하도록 구성된다. 금속접속부재와 합성수지는 공동과 노치에 의해 관축방향, 관축과 직교하는 방향 및 회전방향으로 서로 분리되는 것을 방지하고 있다. 삽입·성형후에 코어형 지지금속부재를 합성수지부의 내측이나 외측, 또는 내외측에 삽입한다. 그 후에 삽입한 지지금속부재를 히터등으로 가열하고, 변성 폴리에틸렌층을 가열·융착한다. 다음에 이층을 수지의 팽창에 따른 수지압력에 의해 금속접속부재에 견고하게 부착시킨다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method for producing a pipe joint in which a metal joint member for connecting a metal tube is inserted and molded on one side and a synthetic resin tube joint in which a synthetic resin tube is inserted and fused on the other is firmly coupled. Synthetic resin pipe joint with metal connection member has a cavity formed in the direction of tube axis and orthogonal to tube axis, groove notch is formed to prevent rotation, and the metal connection member is coated with modified polyethylene of booklet. It is then configured to injection mold the crosslinked polyethylene. The metal connecting member and the synthetic resin are prevented from being separated from each other in the tube axis direction, the direction orthogonal to the tube axis, and the rotation direction by the cavity and the notch. After insertion and molding, the core support metal member is inserted into the inside, outside, or inside and outside of the synthetic resin portion. Thereafter, the inserted supporting metal member is heated with a heater or the like, and the modified polyethylene layer is heated and fused. Next, this layer is firmly attached to the metal connecting member by the resin pressure due to the expansion of the resin.
