[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 The utility model provides a technical solution: a pressure-resistant polyurethane insulation pipe, comprising an inner pipe 1, an outer pipe 2, an inner insulation layer 3, a reinforcement layer 4, a reinforcement rib 5, a buffer layer 6, a support 7, a compression spring 8, a movable column 9, a high-elasticity buffer pad 10, a waterproof layer 11, a T-slot 12, a T-shaped cardboard 13, an outer insulation layer 14, an anti-corrosion layer 15, a wear-resistant layer 16, a spring column 17 and a pressure-resistant plate 18, such as Figure 2 and Figure 3 As shown, an inner insulation layer 3 is arranged inside the inner tube 1, and the inner insulation layer 3 increases the insulation effect. A reinforcement layer 4 is arranged outside the inner insulation layer 3, and reinforcement ribs 5 are installed at equal intervals inside the reinforcement layer 4. The reinforcement ribs 5 increase the strength and pressure resistance of the polyurethane insulation pipe to prevent the polyurethane insulation pipe from being easily deformed by pressure and affecting normal use. A buffer layer 6 is arranged outside the reinforcement layer 4, and pillars 7 are installed at equal intervals inside the buffer layer 6. A compression spring 8 is fixedly installed on the upper end of the pillar 7, and a moving column 9 is fixedly installed on the upper end of the compression spring 8. A high-elasticity buffer pad 10 is installed on the outer side of the moving column 9. When the inner tube 1 is subjected to pressure, the compression spring 8 and the high-elasticity buffer pad 10 are elastic, and the compression spring 8 drives the high-elasticity buffer pad 10 to contract, thereby driving the moving column 9 to slide on the pillar 7. A limit block is installed inside the moving column 9, and the limit block slides in the slide groove. The compression spring 8, the moving column 9 and the high-elasticity buffer pad 10 work together to buffer the pressure, reduce the damage of the pressure to the inner tube 1, and prevent the inner tube 1 from rupturing.

[0024] like Figure 2 and Figure 4As shown, a waterproof layer 11 is arranged on the outside of the buffer layer 6. The waterproof layer 11 is made of polyurethane waterproof coating, which increases the waterproofness of the polyurethane insulation pipe and reduces erosion damage. T-shaped grooves 12 are provided on the upper and lower sides and the left and right sides of the surface of the waterproof layer 11. T-shaped clamps 13 are fixedly installed on the upper and lower sides and the left and right sides of the inner side of the outer tube 2.

The outer tube 2 is clamped and installed on the inner tube 1, which is convenient for quick installation of the outer tube 2. When the inner tube 1 and the outer tube 2 need to be disassembled and repaired, the outer tube 2 is pushed, and the T-shaped clamps 13 on the inner side of the outer tube 2 are pulled out from the T-shaped grooves 12, which is convenient for quick disassembly of the outer tube 2 and convenient for repairing the inner tube 1 and the outer tube 2;

[0025] like Figure 1 and Figure 5 As shown, an outer insulation layer 14 is provided on the inner side of the outer tube 2, and the outer insulation layer 14 increases the insulation performance of the outer tube 2. An anti-corrosion layer 15 is provided on the outer side of the outer insulation layer 14. The anti-corrosion layer 15 is made of polytetrafluoroethylene material, which increases the corrosion resistance of the polyurethane insulation pipe and avoids the corrosion and rupture of the polyurethane insulation pipe due to long-term use, thereby increasing the maintenance cost. A wear-resistant layer 16 is provided on the outer surface of the outer tube 2, and the wear-resistant layer 16 is made of polyethylene wear-resistant coating, which increases the wear resistance of the polyurethane insulation pipe and avoids the polyurethane insulation pipe from being severely worn. It is heavy and has poor practicality. The wear-resistant layer 16 prolongs the service life of the polyurethane thermal insulation pipe. Spring columns 17 are evenly installed on the upper and lower, left and right sides of the outer surface of the outer tube 2. A pressure-resistant plate 18 is installed on the upper end of the spring column 17. When the outer tube 2 is hit, the pressure-resistant plate 18 and the spring column 17 are hit first. The pressure-resistant plate 18 shrinks under the action of the spring column 17, which can buffer the impact of the external impact force on the outer tube 2, increase the pressure resistance and impact resistance of the outer tube 2, avoid direct impact on the outer tube 2, and play a role in protecting the outer tube 2.
