Description

Technical Field

[0001] The utility model relates to the technical field of PE pipelines, in particular to a heat insulation and heat preservation structure for PE pipelines. Background Technique

[0002] Most PE pipes are used in fields such as building water supply, building drainage, buried drainage pipes, and building heating. When PE pipes are in use, they are prone to damage. Therefore, a heat insulation and heat preservation sleeve structure for underground protective PE pipelines is required to protect the PE pipelines.

[0003] For example, the published document with the application number 202321957997.0 discloses an underground protective PE pipeline sleeve. This utility model enables the PE pipeline to be used normally and not be frozen when the temperature is low in winter, thereby improving the service life of the PE pipeline. However, during the use of this PE pipeline sleeve, when splicing the entire sleeve according to the length of the PE pipeline, external connecting plates and bolts need to be used for step-by-step screwing and assembly, resulting in low assembly efficiency and affecting the overall working efficiency. Moreover, the protruding connecting plates also increase the external convex volume of the entire sleeve, and the overall landfill thickness and the overall thickness of the pipeline are not uniform at the connection and other positions.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and a heat insulation and heat preservation structure for PE pipelines is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a heat insulation and heat preservation structure for PE pipelines to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A heat insulation and heat preservation structure for PE pipelines, including a protective pipe. A plug-in ring is fixedly installed at the left end of the protective pipe. Four positioning holes are evenly distributed on the outer surface of the plug-in ring. A slot is opened at the right end of the protective pipe. Four grooves are evenly distributed on the right side of the outer surface of the protective pipe. A spring is fixedly installed on the inner surface of the groove. One end of the spring close to the opening of the groove is fixedly installed with a clamping plate. A plug pin is fixedly arranged in the middle of the surface of the clamping plate on the side connected to the spring.

[0007] Preferably, the inner diameter of the plug-in ring is greater than the opening diameter in the middle of the protective pipe, and the plug-in ring corresponds to the slot in position and matches in size.

[0008] Preferably, the plug pin is located inside the spring, penetrates through the protective pipe and slides into the slot. The surface of the plug pin near the opening of the slot is set as an inclined surface.

[0009] Preferably, the protective pipe is composed of a PE pipe sleeve, a polyethylene thermal insulation material layer, a composite silicate thermal insulation material layer, and a ceramic wear-resistant layer, and the PE pipe sleeve is the base layer of the entire protective pipe.

[0010] Preferably, a polyethylene thermal insulation material layer is fixedly installed on the outer surface of the PE pipe sleeve, a composite silicate thermal insulation material layer is fixedly installed on the outer surface of the polyethylene thermal insulation material layer, and a ceramic wear-resistant layer is fixedly arranged on the outer surface of the composite silicate thermal insulation material layer.

[0011] Preferably, limiting rings are uniformly distributed and fixedly installed on the inner surface of the PE pipe sleeve, and the limiting rings are rubber material rings that can be extruded and deformed.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] 2. Through the settings of the insertion ring, positioning hole, slot, groove, spring, buckle plate, and bolt of the present utility model, the insertion ring of one protective pipe is inserted into the slot of another protective pipe. The insertion ring uses the inclined surface to push the bolt to move outward, pushing the buckle plate to stretch the spring. When the bolt aligns with the positioning hole, the spring will pull the buckle plate to insert the bolt into the positioning hole, thereby fixedly connecting the two protective pipes. The length of the entire protective pipe can be flexibly spliced according to the length of the PE pipe for adaptive use, making it more flexible to use and the installation more convenient and efficient;

[0014] 1. Through the settings of the protective pipe, PE pipe sleeve, polyethylene thermal insulation material layer, composite silicate thermal insulation material layer, ceramic wear-resistant layer, and limiting ring of the present utility model, the PE pipe is inserted into the PE pipe sleeve, and the PE pipe sleeve wraps the PE pipe. At this time, the PE pipe will squeeze the limiting ring, and the elastic force of the rubber of the limiting ring itself will generate elasticity to squeeze and fix the PE pipe, thereby improving the stability and firmness of the installation and insertion of the PE pipe, making the PE pipe not easy to loosen. The entire protective pipe can maximize the insulation of temperature transfer between the inside and outside by using the polyethylene thermal insulation material layer and the composite silicate thermal insulation material layer, keep the inside of the protective pipe and the PE pipe warm, enable the PE pipe to be used normally when the temperature is low in winter, prevent the PE pipe from freezing and cracking, and improve the service life of the PE pipe. The ceramic wear-resistant layer is used to protect the outermost side of the entire protective pipe to prevent overall wear of the protective pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1-3 shown, a heat insulation and thermal insulation structure for a PE wire pipe includes a protection tube 1. An insertion ring 2 is fixedly installed at the left end of the protection tube 1. Four positioning holes 3 are evenly distributed on the outer surface of the insertion ring 2. A slot 4 is opened at the right end of the protection tube 1. Four grooves 5 are evenly distributed on the right side of the outer surface of the protection tube 1. A spring 6 is fixedly installed on the inner surface of the groove 5. A clamping plate 7 is fixedly installed at one end of the spring 6 close to the opening of the groove 5. A plug 8 is fixedly arranged in the middle of the surface of the clamping plate 7 on the side connected to the spring 6.

[0021] By adopting the above technical solutions, the insertion ring 2 can be inserted into the slot 4 for connection; the spring 6 enables the plug 8 to have a force to move into the slot 4 by means of the clamping plate 7; the clamping plate 7 enables the plug 8 to be controlled from the outside of the protection tube 1 by manual; after the insertion ring 2 is connected to the slot 4, the plug 8 is inserted into the positioning hole 3 for fixation.

[0022] Furthermore, the inner diameter of the insertion ring 2 is greater than the opening diameter in the middle of the protection tube 1. The positions of the insertion ring 2 and the slot 4 correspond to each other and are matched in size.

[0023] By adopting the above technical solutions, the insertion ring 2 and the slot 4 can be exactly fitted and inserted.

[0024] Furthermore, the plug 8 is located inside the spring 6 and penetrates through the protection tube 1 and slides into the slot 4. The surface of the plug 8 near the opening of the slot 4 is set as an inclined surface.

[0025] By adopting the above technical solutions, the insertion ring 2 can use the inclined surface to push the plug 8 to extend outward from the protection tube 1, so as to open the slot 4.

[0026] Furthermore, the protective pipe 1 is composed of a PE pipe sleeve 101, a polyethylene thermal insulation material layer 102, a composite silicate thermal insulation material layer 103, and a ceramic wear-resistant layer 104. The PE pipe sleeve 101 is the base layer of the entire protective pipe 1.

[0027] By adopting the above technical solution, the PE pipe is inserted into the PE pipe sleeve 101, and the PE pipe sleeve 101 wraps the PE pipe.

[0028] Furthermore, a polyethylene thermal insulation material layer 102 is fixedly installed on the outer surface of the PE pipe sleeve 101, a composite silicate thermal insulation material layer 103 is fixedly installed on the outer surface of the polyethylene thermal insulation material layer 102, and a ceramic wear-resistant layer 104 is fixedly arranged on the outer surface of the composite silicate thermal insulation material layer 103.

[0029] By adopting the above technical solution, the polyethylene thermal insulation material layer 102 and the composite silicate thermal insulation material layer 103 can isolate the temperature transfer between the inside and outside to the greatest extent, and insulate the inside of the protective pipe 1 and the PE pipe; the ceramic wear-resistant layer 104 protects the outermost side of the entire protective pipe 1 to prevent the overall wear of the protective pipe 1.

[0030] Furthermore, limiting rings 9 are evenly distributed and fixedly installed on the inner surface of the PE pipe sleeve 101. The limiting rings 9 are ring bodies made of rubber that can be extruded and deformed.

[0031] By adopting the above technical solution, the PE pipe will squeeze the limiting rings 9, and the elastic force of the rubber of the limiting rings 9 itself will generate elasticity to squeeze and fix the PE pipe, thereby improving the stability and firmness of the installation and insertion of the PE pipe.

[0032] Working principle: When using the heat insulation and preservation structure for the PE pipeline, first, according to the length of the PE pipeline, insert the insertion ring 2 of one protective pipe 1 into the slot 4 of another protective pipe 1. The insertion ring 2 uses the inclined plane to push the bolt 8 to move outward, pushing the buckle plate 7 to stretch the spring 6. When the bolt 8 aligns with the positioning hole 3, the spring 6 will pull the buckle plate 7 to insert the bolt 8 into the positioning hole 3, thereby fixedly connecting the two protective pipes 1. The protective pipes 1 are spliced to the same length as the PE pipeline. Then, the PE pipeline is inserted into the PE pipeline sleeve 101, and the PE pipeline sleeve 101 wraps the PE pipeline. At this time, the PE pipeline will squeeze the limit ring 9, and the elastic force of the rubber of the limit ring 9 itself will generate elasticity to squeeze and fix the PE pipeline, thereby improving the stability and firmness of the installation and insertion of the PE pipeline, making the PE pipeline not easy to loosen. The entire protective pipe 1 can maximize the isolation of temperature transfer between the inside and outside by using the polyethylene heat insulation material layer 102 and the composite silicate heat insulation material layer 103 to insulate the inside of the protective pipe 1 and the PE pipeline, so that the PE pipeline can be used normally when the temperature is low in winter, prevent the PE pipeline from cracking, and improve the service life of the PE pipeline. The outermost side of the entire protective pipe 1 is protected by the ceramic wear-resistant layer 104 to prevent the overall wear of the protective pipe 1. This is the working principle of the heat insulation and preservation structure for the PE pipeline.
