Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pipeline technology and relates to an insulated pipeline for municipal heating pipeline systems. Background Technology
[0002] Insulated pipes are suitable for transporting various media within the temperature range of -50℃ to 150℃. They are widely used in centralized heating, cooling, and hot oil transportation, as well as in insulation and cold preservation projects in industries such as greenhouses, cold storage, coal mines, petroleum, and chemicals. The insulation structure of external sliding pipes consists of a working steel pipe, a glass wool insulation layer, an aluminum foil reflective layer, stainless steel fastening strips, sliding guide supports, an air insulation layer, an outer protective steel pipe, and an outer anti-corrosion layer. However, the internal insulation layer of this type of pipe is directly integrally formed inside, and it is impossible to strengthen the insulation later. Therefore, a pipe structure that can strengthen the insulation performance later is required. Summary of the Invention
[0003] The purpose of this utility model is to provide an insulated pipe for municipal heating network systems to solve the problems mentioned in the background art.
[0004] The objective of this utility model can be achieved through the following technical solutions:
[0005] An insulated pipe for a municipal heating network system includes a pipe body, a protective pressure sleeve, an outer insulation sleeve, and a clamping plate. Two protective pressure sleeves are fitted around the outside of the pipe body, and an outer insulation sleeve is installed between the two protective pressure sleeves. The outer insulation sleeve is composed of an inner insulation layer and an outer rubber layer. The inner insulation layer is bonded to the inside of the outer rubber layer. Multiple positioning holes are provided on the sides of the outer insulation sleeve.
[0006] In the above-mentioned insulated pipe for a municipal heating network system, a fixing plate is provided at one end of the protective pressure sleeve, a locking bolt is installed inside the fixing plate, and a locking nut is threaded on the top of the locking bolt.
[0007] In the above-mentioned insulated pipe for a municipal heating network system, a clamping plate is connected to the side of the protective sleeve, and one end of the clamping plate is fixed to the side of one of the protective sleeves by screws.
[0008] In the aforementioned insulated pipe for a municipal heating network system, the bottom end of the clamping plate is provided with multiple positioning spikes, and the positioning spikes are pressed into the positioning holes.
[0009] In the above-mentioned insulated pipe for a municipal heating network system, the pipe body is composed of an antibacterial inner layer, an insulation layer and a wear-resistant outer layer. The wear-resistant outer layer is provided with an insulation layer on its inner side, and the insulation layer is provided with an antibacterial inner layer on its inner side.
[0010] In the above-mentioned insulated pipe for a municipal heating network system, an anti-slip sleeve is provided on the inner side of the protective pressure sleeve, and the anti-slip sleeve is bonded to the outer wall of the pipe body.
[0011] Compared with existing technologies, the advantages of this utility model for an insulated pipe used in municipal heating network systems are as follows:
[0012] This application installs two protective pressure sleeves on the outside of the pipeline body. The protective pressure sleeves can protect the pipeline and prevent it from being damaged. The protective pressure sleeves are equipped with clamping plates. When it is necessary to strengthen the insulation of the pipeline body, the outer insulation sleeve is put on the two protective pressure sleeves and then pressed by the clamping plate. When the clamping plate is pressed down, multiple positioning spikes at the bottom of the clamping plate are pressed into the positioning holes, thereby limiting and pressing the outer insulation sleeve. This can effectively improve the insulation effect of the entire pipeline. In addition, the outer rubber layer is set on the outside of the inner insulation layer, which has the effect of corrosion resistance and wear resistance and long service life.
