Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline insulation technology, specifically a spiral-wound pipeline antifreeze and insulation strap. Background Technology
[0002] Insulation tape is mainly used on the side walls of pipes. Traditional insulation materials may not provide sufficient insulation, especially under extreme low temperature conditions. In addition, some insulation tapes require special tools for installation, which increases installation time and cost. The installation process is difficult for non-professionals. At the same time, some insulation materials may gradually degrade after long-term exposure to the outdoor environment, resulting in a weakening of the insulation effect.
[0003] Therefore, in order to correct the above-mentioned defects, we propose a spiral-wound pipe antifreeze and insulation strap. Utility Model Content
[0004] The technical problem solved by this utility model is to propose a spiral-wound pipe antifreeze and heat-insulating strap.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a spiral-wound pipe antifreeze and heat-insulating strap, comprising a strap body, the strap body being composed of an outer metal layer and an inner heat-insulating layer, the strap body having a spiral structure, with every two adjacent spiral rings on the strap body in active contact.
[0006] Furthermore, the belt has notches at the upper end of one side and the lower end of the other side, with the height and width of the two notches being the same.
[0007] Furthermore, the outer metal layer is either an aluminum sheet or a steel sheet.
[0008] Furthermore, the inner insulation layer is either pearl cotton or rock wool.
[0009] Furthermore, the outer metal layer and the inner insulation layer are bonded together.
[0010] Compared with the prior art, the beneficial effects of this utility model are: the thermal insulation tape in this utility model is relatively soft and can be easily wrapped around the outside of the pipe without the need for external tools for fixing. At the same time, after wrapping, each ring is in close contact, which improves the thermal insulation effect. In addition, the entire thermal insulation tape is lightweight, low in cost, and highly efficient in installation. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] This utility model provides a technical solution:
[0018] Please see Figure 1-3 A spiral-wound pipe antifreeze and heat insulation strap includes a strap body 1, which is composed of an outer metal layer 2 and an inner heat insulation layer 3. The strap body 1 has a spiral structure, and there is active contact between every two adjacent spiral rings on the strap body 1. That is, the entire heat insulation strap is spirally wrapped around the pipe. When wrapping, it is only necessary to ensure the tightness, and the middle part does not need to be installed and fixed with external tools.
[0019] In addition, the upper end of one side and the lower end of the other side of the belt 1 have notches 4. The height and width of the two notches 4 are the same. That is, when winding, the edge of the upper and lower spiral rings is overlapped by the edge of the lower spiral ring to ensure tightness and improve the heat preservation effect.
[0020] Specifically, the outer metal layer 2 is either an aluminum sheet or a steel sheet, with steel sheet being preferred. Steel sheet has a certain degree of elasticity and can be wound more tightly.
[0021] Specifically, the inner insulation layer 3 is made of either pearl cotton or rock wool, with pearl cotton being preferred as it is softer and easier to install.
[0022] Specifically, the outer metal layer 2 and the inner insulation layer 3 are bonded together.
[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
