A thermal insulation and corrosion-resistant pipe

Abstract

A thermally insulated and corrosion-resistant pipe includes a pipe body, a protective sleeve covering the middle of the pipe body, an insulating cover movably fitted onto the outside of the protective sleeve, and an elastic clamp fitted onto the outside of the protective sleeve, with screws installed on the elastic clamp. The pipe body includes a pipe body, a flange fixedly connected to the side of the pipe body, and the protective sleeve fixedly wrapped around the outside of the pipe body. The insulating cover is pushed to the joint point, wrapping around the joint of the pipe body. The elastic clamp is then moved to contact the insulating cover, and the screws are tightened. The elastic clamp limits the insulating cover, keeping it at the joint point. The pipe can be disassembled in the reverse manner, allowing for both conventional pipe assembly and disassembly, as well as proper insulation, thus improving overall practicality.

Description

Technical Field

[0001] This utility model belongs to the field of pipeline technology, and in particular relates to a heat-insulating and corrosion-resistant pipeline. Background Technology

[0002] Thermal insulation and corrosion-resistant pipes are composite pipes that integrate corrosion protection and heat preservation functions. Their core advantage is that while preventing the pipe substrate from rusting, they reduce the heat loss of the medium inside the pipe (such as hot water, steam, and hot oil). They are suitable for transportation scenarios that require both temperature maintenance and corrosion prevention.

[0003] Because the insulation layer of thermally insulated and corrosion-resistant pipes occupies a relatively large amount of thickness, the two pipes need to be installed by plugging in to reduce the gaps in the insulation. However, if flange connection is used, a gap needs to be reserved for the installation of screws. After installation, the gap in the insulation sleeve is very large, which results in the relatively low practicality of conventional thermally insulated and corrosion-resistant pipes.

[0004] Therefore, we propose a thermal insulation and corrosion-resistant pipe to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problem of low practicality of conventional heat-insulating and corrosion-resistant pipes, and to propose a heat-insulating and corrosion-resistant pipe.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A thermally insulated and corrosion-resistant pipe includes a pipe body, a protective sleeve covering the middle of the pipe body, an insulation cover movably fitted over the outer side of the protective sleeve, and an elastic clamp fitted over the outer side of the protective sleeve, with screws installed on the elastic clamp. After the pipe body is joined, the insulation cover is pushed to the joining point, covering the joining point of the pipe body. The elastic clamp is then moved to contact the insulation cover, and the screws are tightened. The elastic clamp limits the insulation cover, keeping it at the joining point. The pipe can be disassembled in the reverse manner, allowing the pipe to be both disassembled and assembled like a conventional pipe, while also providing proper insulation, thus improving overall practicality.

[0007] Preferably, the pipe body includes a pipe body, a flange is fixedly connected to the side of the pipe body, and the protective sleeve is fixedly wrapped around the outside of the pipe body. After the flange is connected and fixed to the flange of another pipe body, the insulation cover is pushed outside the flange to shield the flange and reduce heat loss.

[0008] Preferably, the insulation cover includes a movable sleeve, and a collar is fixedly connected to the side of the movable sleeve. The movable sleeve is movably fitted outside the protective sleeve, and the collar is fitted and matched with the flange. By sliding the movable sleeve along the outside of the protective sleeve, the posture of the collar is stabilized, and the collar blocks the heat loss through the flange.

[0009] Preferably, the collar has a limiting groove inside, and the flange engages with the limiting groove. The collar engages with the flange to position the insulation cover in its closed position.

[0010] Preferably, the elastic band includes an elastic band body, and mounting rings are fixedly connected to both ends of the elastic band body. Tightening the screws through the mounting rings tightens the elastic band body to secure it outside the protective sleeve. Tightening the screws further loosens the elastic band body from the protective sleeve, allowing it to resume its movement.

[0011] Preferably, the elastic band further includes a reinforcing block, which is fixedly connected between the elastic band body and the mounting ring. The reinforcing block increases the stability of the angle between the elastic band body and the mounting ring.

[0012] In summary, the technical effects and advantages of this utility model are as follows: After connecting the pipe body, push the insulation cover to the connection point and wrap the pipe body at the connection point with the insulation cover. Move the elastic clamp to contact the insulation cover and tighten the screws. Use the elastic clamp to limit the insulation cover and keep it at the connection point. Similarly, disassemble the pipe by reversing the operation. This allows the pipe to be disassembled and assembled like a regular pipe, while also maintaining proper insulation, thus improving its overall practicality. Attached Figure Description

[0015] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments.

[0016] like Figure 1As shown, a thermally insulated and corrosion-resistant pipe includes a pipe body 2, a protective sleeve 1 wrapped around the middle of the pipe body 2, an insulation cover 3 movably fitted around the outside of the protective sleeve 1, and an elastic clamp 4 fitted around the outside of the protective sleeve 1. Screws 5 are installed on the elastic clamp 4. After the pipe body 2 is joined, the insulation cover 3 is pushed to the joining point, allowing the insulation cover 3 to wrap around the joining point of the pipe body 2. The elastic clamp 4 is then moved to contact the insulation cover 3, and the screws 5 are tightened. The elastic clamp 4 limits the insulation cover 3, keeping it at the joining point. The pipe is then disassembled by reversing the operation.

[0017] like Figure 1 and 2 As shown, the pipe body 2 includes a pipe body 21, and a flange 22 is fixedly connected to the side of the pipe body 21. A protective sleeve 1 is fixedly wrapped around the outside of the pipe body 21. After the flange 22 is connected and fixed to the flange 22 of another pipe body 2, the insulation cover 3 is pushed outside the flange 22 to shield the flange 22 and reduce heat loss.

[0018] like Figure 1 , 2 As shown in Figure 3, the insulation cover 3 includes a movable sleeve 31, with a collar 32 fixedly connected to the side of the movable sleeve 31. The movable sleeve 31 is movably fitted outside the protective sleeve 1, and the collar 32 is fitted and matched with the flange 22. By sliding the movable sleeve 31 along the outside of the protective sleeve 1, the posture of the collar 32 is stabilized, and the collar 32 blocks the outside of the flange 22, preventing heat loss through the flange 22.

[0019] like Figure 1 , 2 As shown in Figure 3, a limiting groove 33 is formed inside the collar 32, and the flange 22 is engaged with the limiting groove 33. The collar 32 is used to engage the flange 22 to position the insulation cover 3 in the closed position.

[0020] like Figure 1 and 4 As shown, the elastic band 4 includes an elastic band body 41, with mounting rings 42 fixedly connected to both ends of the elastic band body 41. Tightening the screws through the mounting rings 42 tightens the elastic band body 41, fixing it to the outside of the protective sleeve 1. Tightening the screws further loosens the elastic band body 41 from the protective sleeve 1, allowing it to resume its movement.

[0021] like Figure 1 and 4 As shown, the elastic hoop 4 also includes a reinforcing block 43, which is fixedly connected between the elastic hoop body 41 and the mounting ring 42. The reinforcing block 43 is used to increase the stability of the angle between the elastic hoop body 41 and the mounting ring 42.

[0022] Working principle: After connecting the pipe body 2, push the insulation cover 3 to the connection point. The insulation cover 3 will wrap around the connection point of the pipe body 2. Move the elastic clamp 4 to contact the insulation cover 3 and tighten the screw 5. Use the elastic clamp 4 to limit the insulation cover 3 and keep the insulation cover 3 at the connection point. Similarly, operate in reverse to disassemble the pipe.

[0023] The above description is only a preferred embodiment of the utility model, but the protection scope of the utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed by the utility model, based on the technical solution and the utility model concept, should be included within the protection scope of the utility model.

[0024] The description briefly mentions the application direction of the utility model in relation to existing technologies known to those skilled in the art without modification, and combines them with the utility model to form a complete technology; it avoids excessive popularization of technologies known to those skilled in the art, in order to help those skilled in the art quickly understand the main content of the utility model.
