[0020] Embodiment

[0021] As shown in Figure 1 and Figure 2 , a kind of anticorrosive heat-insulating pipe connecting pipe fittings, including main pipeline 1 and connecting pipeline 3, sleeve 2 is set on the outside of main pipeline 1, the cross section of main pipeline 1, connecting pipeline 3, sleeve 2 is circular, i.e. main pipeline 1, connecting pipeline 3, sleeve 2 are cylindrical structure, facilitate installation. Sleeve 2 is connected with main pipeline 1 by screw thread, the outer wall surface of main pipeline 1 is equipped with screw thread two 9, and the inner wall of sleeve 2 is equipped with the screw groove two corresponding with screw thread two 9. Sleeve 2 can slide on main pipeline 1, and then be locked by the cooperation of screw thread two 9 and screw groove two. By setting sleeve 2 on the outside of main pipeline 1, the compression resistance of pipe fittings can be effectively enhanced, the stability after pipe fittings and pipeline are connected can be improved, the influence of external force impact or vibration on connecting part is reduced, the effect of strengthening fixation is achieved, so that the connection between main pipeline 1 and connecting pipeline 3 is prevented from loosening after long time use.

[0022] As shown in Figure 3 and Figure 4 , the side wall of connecting pipeline 3 is equipped with slot 5 at both ends, and the cross section of slot 5 is annular. One end of main pipeline 1 is inserted into slot 5, and the inner wall of the end of main pipeline 1 inserted into slot 5 is equipped with screw thread one 8, and the inner wall of one side of slot 5 is equipped with screw groove one 10 corresponding with screw thread one 8. One end of main pipeline 1 is connected with connecting pipeline 3 by the cooperation of screw thread one 8 and screw groove one 10, and the connection between the other side of connecting pipeline 3 and another main pipeline 1 is the same. By setting screw thread and screw groove on the inner wall of slot 5 of connecting pipeline 3 and the inner wall of main pipeline 1, installation is facilitated, professional equipment and professional personnel are not needed for operation, and installation efficiency is improved.
