Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation, in particular to a waterproof, heat-insulating, thermal insulation sleeve. Background Art

[0002] Industrial pipelines are often affected by ambient temperature during use, which can easily cause changes in the temperature of the internal liquid or gas, thus affecting their normal use. Therefore, it is necessary to install an insulation sleeve outside the pipeline to insulate the pipeline and ensure the performance of the pipeline.

[0003] The existing insulation sleeves are still insufficient in terms of waterproof and drainage performance and are difficult to meet the actual use requirements. Although the insulation sleeves can ensure the thermal insulation effect after installation, they cannot achieve complete sealing. Water vapor will enter the gap between the insulation sleeves and the pipes. Especially when the external humidity is high, condensation is prone to occur on the outer surface of the pipes that transport low-temperature gas and liquid. After a long period of accumulation, the lower surface of the pipe is always soaked, which can easily cause corrosion of the pipes and affect the thermal insulation effect. Therefore, the condensed water needs to be discharged.

[0004] Therefore, a novel protective cover which is both waterproof and effectively heat-insulating is badly needed. Utility Model Content

DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0023] Example 1: See Figure 1 - Figure 4In this embodiment, a waterproof heat-insulating heat-preserving sleeve is provided, which is specifically used for industrial pipeline 6 systems, especially for protecting pipeline 6 of low-temperature gas and liquid. These pipelines 6 are exposed to a humid environment and require additional protection to ensure the temperature stability of their contents and prevent corrosion of the pipeline 6 itself. The heat-preserving sleeve specifically includes: a sleeve body 1, the sleeve body 1 is provided with a drain port 11, and a transparent isolation cover 2 is provided on the part of the sleeve body 1 provided with the drain port 11, the isolation cover 2 is formed by bending an elastic material, one side of the isolation cover 2 is open, and a cover 22 is provided on the open side, the sleeve body 1 is provided with two guide grooves 12, and the two side edges of the isolation cover 2 are provided with sliders 21 that are slidably matched with the guide grooves 12.

[0024] Specifically, in this embodiment, when installing the waterproof heat-insulating cover, firstly, the cover body 1 is mounted on the pipe 6 to be protected, ensuring that the drain port 11 is located at the lowest point to facilitate the discharge of moisture. One end of the isolation cover 2 is sealed and the other end is open, and a cover 22 is provided at the open end. The slider 21 provided at the open end of the edge of the isolation cover 2 is first inserted into the guide groove 12, and the isolation cover 2 is pushed to slide along the guide groove 12. The drain port 11 is located between the two guide grooves 12. The position of the isolation cover 2 is adjusted until the isolation cover 2 completely covers the drain port 11. Finally, the open end of the isolation cover 2 is blocked by the cover 22. During daily use, the condensed water in the gap between the sleeve body 1 and the pipeline 6 accumulates and flows out of the drain port 11 under the action of gravity and is collected by the isolation cover 2. The isolation cover 2 is pushed along the direction of the guide groove 12. After the cover 22 is opened, the condensed water is discharged from the cover 22 side of the isolation cover 2. After drainage is completed, the isolation cover 2 and the drain port 11 are wiped to keep them clean and tidy, and the cover 22 is closed to maintain the waterproof and heat-insulating properties of the insulation cover.

[0025] The utility model discharges the condensed water accumulated on the lower surface of the pipe 6 inside the casing 1 through the drain port 11, so that the lower surface of the pipe 6 remains dry, thereby preventing the pipe 6 from being corroded. Through the design of the transparent isolation cover 2, the operator can visually observe the condensed water condition in the isolation cover 2, which is convenient for timely discharge of the condensed water.

[0026] The sleeve 1 is provided with multiple groups of connecting parts 3, and the connecting parts 3 include adhesive tape 31 and buckle 32. The adhesive tape 31 passes through the buckle 32 and then adheres to itself in the reverse direction to form an annular sleeve 1. The sleeve 1 is made of flexible material, which is wrapped around the outer surface of the pipe 6 after being bent. The side to be fixed before the sleeve 1 is fixed is located at the top, wherein the adhesive tape 31 is located on one side of the sleeve 1, and the other side of the sleeve 1 is provided with a buckle 32. The adhesive tape 31 is passed through one side of the buckle 32 to tighten the sleeve 1 in the reverse direction, and the adhesive tape 31 is then fixed by the Velcro structure thereon. The utility model is tightened and fixed by the adhesive tape 31, which is convenient to install, so that the sleeve 1 and the pipe 6 are closely fitted, and the thermal bridge effect is minimized. The junction between the inner wall of the sleeve 1 and the drain port 11 is chamfered, and the drain port 11 is in an inverted cone shape, which helps to guide the condensed water accumulated between the pipe 6 and the sleeve 1 below to flow to the drain port 11, thereby effectively removing the condensed water, keeping the surface of the pipe 6 dry, and preventing corrosion.

[0027] See also Figure 5 The casing 1 includes a waterproof layer 71, a heat insulating layer 72 and a thermal insulation layer 73 from the outside to the inside. The waterproof layer 71 is made of polytetrafluoroethylene (PTFE) material. PTFE has excellent waterproof properties and can effectively prevent moisture from penetrating into the interior of the thermal insulation casing. The thermal insulation layer 72 is made of aluminum silicate fiber. Aluminum silicate fiber has good thermal insulation and heat preservation properties and can effectively reduce heat conduction. The thermal insulation layer 73 uses aerogel as a filling material. The aerogel not only enhances the thermal insulation effect, but also reduces the overall weight, making the thermal insulation casing easier to install and use. The casing 1 adopts a combination of a multi-layer structure (three-layer material) so that the waterproof and heat-insulating thermal insulation casing has both waterproof function and effective heat insulation, meeting the thermal insulation requirements of industrial low-temperature pipelines 6.

[0028] Example 2: See Figure 6 In this embodiment 2, on the basis of embodiment 1, a water-absorbing cotton core 4 is installed at the drain port 11, and the water-absorbing cotton core 4 is filled with color-changing silica gel. The drain port 11 is made of transparent material, and the water-absorbing cotton core 4 is located inside the drain port 11 to collect condensed water flowing down from the outer surface of the pipe 6. Color-changing silica gel is an indicator-type adsorbent. When the water-absorbing cotton core 4 absorbs a certain amount of moisture, the color of the color-changing silica gel will change (for example, blue silica gel has the characteristic that its color changes from blue to red after absorbing moisture), providing an intuitive humidity indication. The operator can observe through the transparent drain port 11 to determine when the water-absorbing cotton core 4 needs to be replaced or cleaned.

[0029] The absorbent cotton core 4 is plugged into the mounting seat 5, and the mounting seat 5 is connected and adapted to the drain outlet 11 through a threaded structure. The operator can remove the mounting seat 5 by rotating it, thereby replacing the absorbent cotton core 4 in the mounting seat 5. By providing an anti-slip texture on the outer surface of the mounting seat 5, the anti-slip texture in this embodiment is composed of a plurality of vertical long grooves, so that the absorbent cotton core 4 can be easily replaced even in a slippery environment.

Those skilled in the art of the present utility model may make various modifications or additions to the specific embodiments described, or replace them in similar ways, as long as they do not deviate from the contents of the present utility model specification or exceed the scope defined in the claims, they shall all fall within the protection scope of the present utility model.
