Detailed Description

As shown in fig. 1-3, a prefabricated overhead thermal insulation pipe comprises a core pipe 1, wherein an outer pipe 2 concentric with the core pipe 1 is sleeved outside the core pipe 1, a plurality of supporting components are uniformly distributed on the outer edge of the middle of the core pipe 1, the supporting components comprise a plurality of arc-shaped plates 3 uniformly distributed and arranged according to the circumference of the axis of the core pipe 1, the arc-shaped plates 3 are fixedly connected with the core pipe 1, and the outer edges of the arc-shaped plates 3 are in contact with the inner edge of the outer pipe 2.

A baffle ring 8 is fixed at the left end of the core tube 1, a plugging ring 9 is fixed at the right end of the core tube 1, a supporting ring 10 is fixed at the left end of the plugging ring 9, a limiting ring 4 is fixed at the left end of the outer tube 2, the limiting ring 4 and the blocking ring 9 are flush with the outer edge of the outer tube 2, a plurality of pins 6 are uniformly distributed on the circumference of the limiting ring 4, the pins 6 penetrate through the limiting ring 4 and are rotatably connected with the limiting ring 4, a baffle 7 is fixed at the end part of the limiting ring 4 in the outer tube 2, one end of the baffle 7 is fixedly connected with the pins 6, the blocking ring 8 is tightly propped against the limiting ring 4, the pins 6 are positioned between the outer tube 2 and the core tube 1, the blocking ring 8 is positioned between the baffle 7 and the limiting ring 4, the blocking ring 8 is contacted with the baffle 7, an injection hole 5 is arranged on the limiting ring 4, the left end of the blocking ring 9 is contacted with the right end of the outer tube 2, and the support ring 10 is inserted in the outer tube 2, the outer edge of the support ring 10 is in contact with the inner edge of the outer pipe 2, and heat-insulating filler is filled between the outer pipe 2 and the core pipe 1 and is foam rubber.

During this insulating tube production, pack into outer tube 2 with 1 left end of core pipe in 2 right-hand members of outer tube, make and keep off ring 8 and tightly support spacing ring 4, keep off when ring 8 tightly supports spacing ring 4, outer tube 2 right-hand members tightly support stifled ring 9, and simultaneously, prop ring 10 and peg graft in 2 right-hand members of outer tube, a plurality of supporting components can support outer tube 2, then rotate pin 6, make and keep off ring 8 and be located between spacing ring 4 and baffle 7, core pipe 1 and outer tube 2 are stably connected this moment, spacing ring 4 and stifled ring 9 can carry out the shutoff to the annular cavity between core pipe 1 and the outer tube 2, annotate the foaming adhesive in above-mentioned annular cavity through annotating hole 5, then will annotate the shutoff of hole 5 can.
