A heat insulation cotton pipe sleeve for quick installation at a pipe elbow

Abstract

This utility model discloses a thermal insulation sleeve for quick installation at pipe bends, comprising a straight section sleeve and a bent section sleeve, which are connected by a strap. The bent section sleeve has a V-groove and a straight cut, one end of which connects to the V-groove, and the other end connects to the end of the bent section sleeve. The straight and bent sections sleeve are fitted over the pipe, with the V-groove located at the pipe bend. Adhesive strips are provided on the cut surfaces of the straight cut and the V-groove, and are used to seal the cuts after installation. This utility model uses a pre-cut V-groove, ensuring a perfect fit with the pipe bend during sleeve installation, preventing the thermal insulation sleeve from being squeezed during bending and facilitating installation at bends. The sleeve is also installed using a strap for pulling, making installation easier and reducing the risk of breakage.

Description

Technical Field

[0001] This utility model relates to the field of pipeline insulation technology, and in particular to an insulation cotton sleeve for quick installation at pipeline bends. Background Technology

[0002] When stainless steel and PP-R pipes are at low temperatures, the water inside will solidify and expand, causing damage to the pipes. Therefore, it is necessary to wrap the outside of the pipes with insulation cotton for insulation. However, current insulation cotton wrapping for stainless steel and PP-R pipes is difficult to install at pipe bends. The insulation cotton is bent and squeezed at bends, resulting in increased density of the insulation cotton in that area, making it difficult to install the sleeve. The sleeve is also difficult to move at bends during installation, requiring two people to drag it during installation, and it is also easy to damage the insulation cotton sleeve. Utility Model Content

[0003] To address the aforementioned problems, this utility model aims to provide an insulation cotton sleeve for quick installation at pipe bends, thereby solving the problem of difficulty in installing insulation cotton sleeves at pipe bends.

[0004] The technical problem solved by this utility model can be achieved by the following technical solution: a thermal insulation sleeve for quick installation at pipe bends, comprising a straight section sleeve and a bent section sleeve, wherein the straight section sleeve and the bent section sleeve are connected by a binding element, the bent section sleeve having a V-groove and a straight cut, one end of the straight cut being connected to the V-groove and the other end being connected to the end of the bent section sleeve. The straight section sleeve and the bent section sleeve are fitted over the pipe, and the V-groove is located at the bend of the pipe.

[0005] A rubber strip is provided on the cut surface of the straight cut, and a rubber strip is provided on the cut surface of the V-groove.

[0006] The binding component includes a first binding band, a second binding band, and a buckle. The buckle has three square holes. Both ends of the first binding band are fixed to the outer wall of the bent section of the tube sleeve. The two ends of the first binding band are connected end to end to form a loop. The first binding band passes through the first square hole. One end of the second binding band is fixed to the outer wall of the straight section of the tube sleeve, and the other end is a free end. The second binding band passes through the second square hole and the third square hole in sequence.

[0007] The V-groove is cut to a depth of 2 / 3 of the pipe sleeve diameter, with the center of the bend's curvature as the origin. The included angle of the V-groove is 15˚.

[0008] Compared with the prior art, this utility model has the following advantages: The utility model adopts a pre-cut V-groove, which fits perfectly with the pipe bend during sleeve installation, avoiding the insulation cotton sleeve from being squeezed when bending, which is beneficial to the installation of insulation cotton at the bend; the sleeve is installed by pulling with a strap, which makes the installation easier and the sleeve is less likely to break.

Detailed Implementation

[0010] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0011] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0012] Combined with appendix Figures 1 to 3 As shown in the figure, this embodiment discloses an insulation cotton sleeve for quick installation at pipe bends, including a straight section sleeve 1 and a bent section sleeve 2. The straight section sleeve 1 and the bent section sleeve 2 are connected by a binding element. The bent section sleeve 2 has a V-groove 4 and a straight cut 3. One end of the straight cut 4 is connected to the V-groove 3, and the other end of the straight cut 4 is connected to the end of the bent section sleeve 2. The straight section sleeve 1 and the bent section sleeve 2 are fitted over the pipe, and the V-groove 3 is located at the bend of the pipe.

[0013] An adhesive strip 5 is provided on the cut surface of the straight cut 4 and the cut surface of the V-groove 3, which are used to fit the cut surfaces after the sleeve is installed in place.

[0014] The binding component includes a first binding band 6, a second binding band 7, and a buckle 8. The buckle 8 has three square holes. Both ends of the first binding band 6 are fixed to the outer wall of the bent section sleeve 2. The two ends of the first binding band 6 are connected end to end to form a loop. The first binding band 6 passes through the first square hole to connect the buckle 8 to the bent section sleeve 2. One end of the second binding band 7 is fixed to the outer wall of the straight section sleeve 1, and the other end is a free end. The second binding band 7 passes through the second square hole and the third square hole in sequence.

[0015] Depending on the desired bending angle, the V-groove 3 is cut to a depth of 2 / 3 of the pipe sleeve diameter, with the center of the elbow curvature as the origin. The included angle of the V-groove 3 is 15˚, suitable for 90˚ elbows.

[0016] During installation, first, put the straight section pipe sleeve 1 and the bent section pipe sleeve 2 onto the pipeline respectively. The section with the straight cut 4 of the bent section pipe sleeve 2 is sleeved at the pipe bend. Then, pass the second bundle 7 through the second square hole and the third square hole on the buckle 8 in sequence. Then, grasp the free end of the second bundle 7 and pull it towards the direction of the straight section pipe sleeve 1 to move the bent section pipe sleeve 2 on the pipeline until the V-groove 3 on the bent section pipe sleeve 2 fits into the pipe bend. Then, tear off the adhesive strips 5 on the straight cut 4 and the V-groove 3, and forcefully press the two sides of the straight cut 4 and the V-groove 3 together to complete the installation of the pipe sleeve.

[0017] This utility model employs pre-cut V-grooves 3 and straight cuts 4. During sleeve installation, the V-grooves 4 fit snugly against the pipe bend, preventing the insulation sleeve from being squeezed during bending and facilitating the installation of the insulation at the bend. The sleeve is installed using a tensioning strap, ensuring the V-grooves 3 fit snugly against the pipe bend, making installation easier and reducing the likelihood of damage to the sleeve.

[0018] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
