Example 1

Referring to fig. 1-5, the present invention provides a technical solution:

polyethylene polymer high sealed fire control composite pipe, including body 1, first end both ends inner wall department of body 1 has all seted up trepanning 11, the cover is equipped with reinforcement sleeve 12 in the trepanning 11 that is located the 1 head end of body, reinforcement sleeve 12 is the annular platelike structure that stainless steel material made, annular 121 has all been seted up to first end both ends edge of reinforcement sleeve 12 surface, the cover is equipped with sealing washer 122 in the annular 121, the tip through with reinforcement sleeve 12 embolias the trepanning 11 in, can make body 1 extrude sealing washer 122 with reinforcement sleeve 12, it is sealed by sealing washer 122 to make between body 1 and the reinforcement sleeve 12, prevent to leak. Through establishing the reinforcing sleeve 12 cover between the junction of two bodys 1 for two bodys 1 are carrying out the butt fusion back, and reinforcing sleeve 12 supports the inboard of two bodys 1 junctions, increases the joint strength of body 1, reaches the purpose of resisting high water pressure.

In this embodiment, the joint reinforcing structure 2 is sleeved at the periphery of the joint of the two pipe bodies 1, and the joint reinforcing structure 2 includes two half-sleeve plates 21 respectively sleeved at the left and right sides of the pipe body 1 and a plurality of abutting plates 22 sleeved in the half-sleeve plates 21. Half lagging 21 is half annular platelike structure, and half lagging 21's first and last both ends homogeneous body shaping has flange 213, through bolt fixed connection between two adjacent flange 213, overlaps through half lagging 21 cover two in the outside of two body 1 junctions and uses the bolt to fix flange 213 on half lagging 21 two and can reach the purpose of fixed joint seam additional strengthening 2 on body 1, makes joint seam additional strengthening 2 can cover including the junction of two bodies 1.

Specifically, the inner wall of the half sleeve plate 21 is provided with a hollow groove 211, the bottom of the hollow groove 211 is provided with a plurality of kidney-shaped holes 2111, the end face of the outer side of the abutting plate 22 is tightly welded with a plurality of limiting rods 223, and the limiting rods 223 penetrate through the kidney-shaped holes 2111, so that the abutting plate 22 is sleeved in the hollow groove 211, and the abutting plate 22 is in sliding connection with the half sleeve plate 21 under the action of the limiting rods 223. The hanging plate is tightly welded at the tail end of the limiting rod 223, and the size of the hanging plate is larger than that of the waist-shaped hole 2111, so that the supporting plate 22 can be prevented from being separated from the empty groove 211 under the limitation of the hanging plate.

Further, the hollow groove 211 is sleeved at the outer side of the joint of the two pipe bodies 1. Make seam additional strengthening 2 can avoid with the junction direct contact of two bodys 1, prevent that the deformation that the tip of two bodys 1 takes place when the butt fusion can support half lagging 21 and lead to half lagging 21 to be difficult to laminate mutually with the surface of body 1.
