Abstract

This invention discloses one kind of pipeline attachment installment, including the pipeline articulate department, wraps the synthesis, the seal packing collar and the tube body, wraps on the synthesis to be equipped with ring groove, states the wrap synthesis Shang Huan trough base is equipped with the belt front the trench, the trench and the PE liner card gathers, the PE liner base is equipped with the oylet, the PE liner front part endophragm is equipped with assumes the arrow capitate trench, compression-joins the purple copper collar base endophragm to be equipped with ring groove, the PE liner with compression-joins the purple copper collar sleeve joint, because this invention wrap synthesis Shang Huan trough base is equipped with the belt front the trench, the trench and the PE liner card gather, the PE liner endophragm is equipped with assumes the arrow capitate trench, Compression-joins the purple copper collar endophragm to be equipped with ring groove, compression-joins purple copper collar inserts in the PE liner, to fixedly compression-joins purple copper collar, causes the offensive to compression-join purple copper collar does not shift.

Description

technical field [0001] The invention relates to a pipeline joint device, especially for various large, medium and small joints of aluminum-plastic composite pipes, PEX and plastic pipes. Background technique [0002] In the prior art, the applicant once designed joints for aluminum-plastic composite pipes and plastic pipes, and applied for a Chinese invention patent, the patent number is ZL00116071.0, and the authorized announcement number is CN1128305C. It is used for the connection of aluminum-plastic composite pipes or plastic pipes. It includes: a pipe joint body with a fitting body, a crimping ring, and a high-elastic sealing ring; High elastic sealing ring on the edge of the ring groove; there is a circular viewing hole near the front end of the crimping sleeve to check whether the pipe body is installed in a safe positioning position. After the pipe joint is combined with the pipe body, the fit is stable. Due to the high elasticity Sealing ring, so its function is no...
