Description

Technical Field

[0001] This utility model relates to the field of plastic pipe technology, specifically to an insulated plastic pipe for centralized heating projects. Background Technology

[0002] Plastic pipes are a general term for pipes made of plastic. Plastic pipes are favored by the pipeline engineering industry due to their lightweight, hygiene and safety, low water flow resistance, energy saving, metal saving, improved living environment, long service life, and safety and convenience. Insulated plastic pipes, on the other hand, are plastic pipes with added insulation materials inside, providing thermal insulation.

[0003] Existing plastic pipes are usually just simple plastic pipe bodies, and most of them do not have shock-absorbing or pressure-resistant structures. When plastic pipes transport media, they often vibrate. Long-term vibration can easily lead to fatigue and brittleness of the plastic pipes, resulting in pipe damage. In addition, the vibration process often generates a lot of noise, affecting the environment. At the same time, because plastic pipes have poor pressure resistance, they are easily deformed and damaged when subjected to external forces or objects.

[0004] Therefore, we propose an insulated plastic pipe for centralized heating projects. Utility Model Content

[0005] The purpose of this invention is to provide an insulated plastic pipe for centralized heating projects, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a thermally insulated plastic pipe for centralized heating projects, comprising a fixed frame, a U-shaped frame, and a plastic pipe. The fixed frame houses the U-shaped frame, and a rubber sleeve is fixedly installed inside the U-shaped frame. A plastic pipe is fixedly installed inside the rubber sleeve, and an insulation layer is fixedly installed inside the plastic pipe. An inner pipe is fixedly installed inside the insulation layer. Buffer plates are fixedly installed on both sides of the U-shaped frame. Sliding grooves are provided on both sides of the fixed frame, and two buffer plates are slidably connected within their respective sliding grooves. A pressure-resistant bracket is fixedly installed at the top of the U-shaped frame. Multiple dampers are fixedly installed at the bottom of each of the two sliding grooves, and the output ends of the multiple dampers are fixedly installed on their respective buffer plates. Springs are sleeved on the outer sides of each of the multiple dampers. A first rubber seat is fixedly installed at the top of each of the two sliding grooves.

[0007] Optionally, the top ends of the multiple springs are fixedly mounted on the buffer plate, and the bottom ends of the multiple springs are fixedly mounted on the bottom end of the slide groove. This design is beneficial to the use of this type of thermal insulation plastic pipe.

[0008] Optionally, the insulation layer is made of polyurethane foam material, which can achieve the insulation effect.

[0009] Optionally, multiple positioning rods are fixedly installed on both sides of the bottom of the pressure-resistant bracket at the U-shaped frame. The top of the fixed frame is provided with through holes corresponding to the multiple positioning rods. The bottom ends of the multiple positioning rods pass through the through holes and into the first rubber seat and are respectively fixedly installed on the corresponding buffer plate. This design is beneficial to the use of this type of thermal insulation plastic pipe.

[0010] Optionally, a second rubber seat is fixedly installed at the bottom of the fixed frame. The second rubber seat can provide secondary cushioning when the U-shaped frame is pressed down and deformed by the rubber sleeve.

[0011] Optionally, multiple mounting plates are fixedly installed on both sides of the fixing frame, and each of the mounting plates has pre-drilled mounting holes. The installation and fixing of this type of thermal insulation plastic pipe is facilitated by the cooperation of external bolts and mounting holes.

[0012] Optionally, pipe heads are fixedly installed at both the front and rear ends of the plastic pipe, and a connecting pipe fitting is hot-melt welded to the outside of one of the pipe heads. The connecting pipe fitting facilitates the hot-melt welding of two adjacent insulated plastic pipes together.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Through the coordinated use of the fixed frame, U-shaped frame, pressure-resistant support, rubber sleeve, buffer plate, first rubber seat, positioning rod, second rubber seat, damper, spring and slide groove, the plastic pipe can be subjected to multiple buffering and shock absorption when vibration occurs. This prevents the plastic pipe from fatigue and becoming brittle due to prolonged vibration, thus avoiding damage and affecting the service life of the pipe. At the same time, it can prevent vibration from causing noise that affects the environment. Furthermore, the pressure-resistant support and fixed frame can provide support and protection for the plastic pipe during use, preventing deformation and damage when the plastic pipe is subjected to external pressure.

[0020] Please see Figures 1 to 3 This utility model provides an insulated plastic pipe for centralized heating projects, including a fixed frame 1, a U-shaped frame 2, and a plastic pipe 7. The fixed frame 1 is equipped with a U-shaped frame 2, and a rubber sleeve 4 is fixedly installed on the inner side of the U-shaped frame 2. The plastic pipe 7 is fixedly installed on the rubber sleeve 4, and an insulation layer 18 is fixedly installed on the inner side of the plastic pipe 7. An inner pipe 9 is fixedly installed on the inner side of the insulation layer 18. Buffer plates 10 are fixedly installed on both sides of the U-shaped frame 2. Slide grooves 17 are provided on both sides of the fixed frame 1. The two buffer plates 10 are slidably connected in the corresponding slide grooves 17. A pressure-resistant bracket 3 is fixedly installed at the top of the U-shaped frame 2. Multiple dampers 15 are fixedly installed at the bottom of the two slide grooves 17. The output ends of the multiple dampers 15 are fixedly installed on the corresponding buffer plates 10. Springs 16 are sleeved on the outer side of the multiple dampers 15. A first rubber seat 11 is fixedly installed at the top of the two slide grooves 17.

[0021] The top ends of multiple springs 16 are fixedly installed on the buffer plate 10, and the bottom ends of multiple springs 16 are fixedly installed on the bottom of the slide groove 17. This design is beneficial to the use of this type of insulated plastic pipe. The insulation layer 18 is made of polyurethane foam material, which can achieve the insulation effect. Multiple positioning rods 12 are fixedly installed on both sides of the U-shaped frame 2 at the bottom of the pressure-resistant bracket 3. The top of the fixing frame 1 has through holes 13 corresponding to the multiple positioning rods 12. The bottom ends of the multiple positioning rods 12 pass through the through holes 13 and into the first rubber seat 11 and are respectively fixedly installed on the corresponding buffer plate 10. This design is beneficial to the use of this type of insulated plastic pipe. The design is conducive to the use of this type of thermal insulation plastic pipe. A second rubber seat 14 is fixedly installed at the bottom of the inner side of the fixing frame 1. The second rubber seat 14 can provide secondary cushioning when the U-shaped frame 2 is pressed down and squeezed by the rubber sleeve seat 4. Multiple mounting plates 5 are fixedly installed on both sides of the fixing frame 1, and each mounting plate 5 has a reserved mounting hole. The installation and fixing of this type of thermal insulation plastic pipe is facilitated by the cooperation of external bolts and mounting holes. Pipe heads 8 are fixedly installed at both the front and rear ends of the plastic pipe 7. A connecting pipe fitting 6 is hot-melt welded to the outside of one of the pipe heads 8. The connecting pipe fitting 6 facilitates the hot-melt welding of two adjacent thermal insulation plastic pipes to each other.

[0022] Working principle: During use, when the medium being transported in the inner tube 9 vibrates, the inner tube 9 will cause the insulation layer 18, plastic tube 7, U-shaped frame 2, and buffer plate 10 to slide up and down within the fixed frame 1. When the buffer plate 10 slides downward, it will compress the spring 16 and damper 15, which, together with the rubber sleeve 4, will press the second rubber seat 14 to buffer and reduce vibration. When the buffer plate 10 slides upward, it can press the first rubber seat 11 to buffer and reduce vibration, thereby eliminating the potential energy during vibration. When the pressure-resistant bracket 3 is subjected to external pressure, it will cause multiple positioning rods 12 to press down, causing the U-shaped frame 2 to retract to the fixed position. Inside the frame 1, the bottom ends of the two sides of the final pressure-resistant support 3 abut against the top of the fixed frame 1 for support, thereby preventing pressure from being transmitted to the plastic pipe 7 and causing damage. This type of insulated plastic pipe for centralized heating projects is easy to use. Through the above components, when the insulated plastic pipe vibrates, it can provide multiple buffering and shock absorption for the plastic pipe 7, preventing long-term vibration from causing fatigue and embrittlement of the plastic pipe 7 and resulting in damage, which would affect the service life of the pipe. At the same time, it can prevent vibration from causing noise that affects the environment. Furthermore, during use, the pressure-resistant support 3 and the fixed frame 1 can provide support and protection for the plastic pipe 7, preventing the plastic pipe 7 from being deformed and damaged when subjected to external pressure.
