Description

Technical Field

[0001] This utility model relates to the field of underfloor heating pipe technology, specifically a graphene-based high thermal conductivity PERT underfloor heating pipe. Background Technology

[0002] Underfloor heating pipes refer to the pipes used as the carrier for the circulation of low-temperature hot water in a low-temperature hot water radiant floor heating system (referred to as underfloor heating). Underfloor heating pipes are an important component of the underfloor heating system, which mainly consists of a gas-fired wall-hung boiler, underfloor heating pipes, and a manifold.

[0003] A search of existing published patents revealed that, according to patent number CN202323044031.0, entitled "A type of underfloor heating pipe," the pipe comprises a pipe body laid between a floor and an insulation board. The outer surface of the pipe body is provided with several sets of positioning components. Each positioning component includes several protrusions fixed to the outer surface of the pipe body. Each protrusion has an arc-shaped concave surface on its outer surface away from the pipe body. Several anti-slip protrusions are fixed on the arc-shaped concave surface to increase friction and enhance connection. The arc-shaped concave surface is arranged circumferentially around the pipe body. A strap is bound between the outer surfaces of the arc-shaped concave surface and to the arc-shaped concave surface of the protrusions, which is then fixed to the insulation board. Advantages: easy to fix, not easily rotated or deformed, simple structure, and low cost.

[0004] However, the positioning components of the aforementioned pipes affect the bending of the pipes during use, which impacts their use when laying underfloor heating pipes. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a graphene-based high thermal conductivity PERT underfloor heating pipe, which solves the problem of positioning components affecting pipe bending and thus impacting the use of underfloor heating pipes during installation.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: a graphene high thermal conductivity PERT underfloor heating pipe, comprising: a pipe, a marking line provided on the surface of the pipe, a positioning strip fixedly connected to the surface of the pipe, and an installation component provided on the pipe;

[0009] The installation assembly includes a limiting ring disposed on the surface of the pipe. A limiting groove is formed in the inner wall of the limiting ring. A mounting bracket is fixedly connected to the lower part of the surface of the limiting ring. The mounting bracket has mounting holes on its surface.

[0010] Preferably, the limiting groove has the same width as the positioning strip, and the positioning strip and the marking line are set at a radial angle of 90 degrees.

[0011] Preferably, the pipe includes a flame-retardant layer, the positioning strip is disposed on the surface of the flame-retardant layer, a heat-resistant layer is fixedly connected inside the flame-retardant layer, a PE layer is fixedly connected to the outer surface of the heat-resistant layer, an insulation layer and a graphene thermally conductive layer are disposed on the outer surface of the PE layer, and a pressure-resistant layer is disposed on the outer surface of the graphene thermally conductive layer and the insulation layer.

[0012] Preferably, a heat-conducting hole is provided on the upper part of the surface of the pressure-resistant layer.

[0013] Preferably, both the insulation layer and the graphene thermal conductive layer are semi-circular in shape, and the insulation layer and the graphene thermal conductive layer have the same diameter.

[0014] Preferably, the sealing lines of the insulation layer and the graphene thermal conductive layer are arranged parallel to the marking lines.

[0015] Preferably, the outer surface of the pipe is provided with scale lines, and the mounting bracket and the positioning strip are arranged at a radial angle perpendicular to each other.

[0016] Beneficial effects

[0017] This invention provides a graphene-based high thermal conductivity PERT underfloor heating pipe, which, compared with the prior art, has at least the following advantages:

[0018] Install a limit ring, pull it to slide it along the positioning strip, and at the desired fixed position, drive the fixing nail into the ground through the mounting hole to secure the mounting bracket and the limit ring. The pipe is then fixed in place by the cooperation of the limit groove and the positioning strip. When the pipe needs to be bent, bend it perpendicular to the marked line; the positioning strip and mounting components do not affect the bending of the pipe. The mounting bracket and positioning strip work together to keep the mounting bracket parallel to the ground and the pipe at a fixed angle to the ground, preventing pipe deflection during backfilling and improving heat conduction.

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.

[0025] Example 1:

[0026] Please see Figure 1-4 The present invention provides a technical solution: a pipe 1, a marking line 2 is provided on the surface of the pipe 1, a positioning strip 3 is fixedly connected to the surface of the pipe 1, and an installation component 4 is provided on the pipe 1;

[0027] Mounting assembly 4 includes a limiting ring 401, which is disposed on the surface of pipe 1. A limiting groove 402 is formed in the inner wall of the limiting ring 401. A mounting bracket 403 is fixedly connected to the lower part of the surface of the limiting ring 401. The surface of the mounting bracket 403 is provided with mounting holes 404. The outer surface of pipe 1 is provided with scale lines. The mounting bracket 403 is set at a perpendicular radial angle to the positioning strip 3.

[0028] Analysis of the above: A limiting ring 401 is installed. Pulling the limiting ring 401 causes it to slide along the positioning strip 3. At the desired fixed position, a fixing nail is driven into the ground through the mounting hole 404, fixing the mounting bracket 403 and the limiting ring 401. The pipe 1 is fixed in place by the cooperation of the limiting groove 402 and the positioning strip 3. When the pipe 1 needs to be bent, it is bent perpendicular to the marking line 2. The positioning strip 3 and the mounting assembly 4 do not affect the bending of the pipe 1. The mounting bracket 403 and the positioning strip 3 work together to keep the mounting bracket 403 parallel to the ground, and the pipe 1 maintains a fixed angle with the ground. During backfilling, the pipe 1 will not deflect, improving heat conduction.
