and the two plastic pipes are respectively and fixedly connected with the first annular groove and the second annular groove at the two ends of the middle hot-melting connecting piece through hot melting devices in a hot melting way.
The first pipe body, the annular partition and the second pipe body are of an integral structure.
The first pipe body and the annular separating piece are of an integral connecting structure, one side, far away from the first pipe body, of the annular separating piece is provided with an inserting portion, and the inner wall of the second pipe body is provided with a slot for the inserting portion to be matched and inserted.
The first pipe body is a metal pipe.
The first pipe body is a metal plastic composite pipe and comprises a metal inner pipe and a plastic layer arranged outside the metal inner pipe.
The hot melt plastic pipe is a PPR pipe or a PE pipe.
Has the advantages that:
the utility model designs a first pipe body as a water channel as an inner lining on the basis of the existing plastic connecting pipe, an annular cavity is formed between the plastic connecting pipe and the first pipe body, and the annular cavity is divided into a first annular groove and a second annular groove which are symmetrically arranged up and down along the axial direction of the pipe body by an annular separator; and the two plastic pipes are respectively and fixedly connected with the first annular groove and the second annular groove at the two ends of the middle hot-melting connecting piece through hot melting devices in a hot melting way. When the intubate is docked after the hot melt, as the inside lining first body can play the technical problem that the plastic tubing joint of preventing the hot melt receives extrusion deformation and blocks up the pipeline.
