Description

Technical Field

[0001] The utility model relates to the technical field of pipelines, in particular to a PERT floor heating pipe with thermal oxygen aging resistance. Background Art

[0002] Floor heating pipe refers to a kind of pipe used as a carrier for the circulation of low-temperature hot water in the low-temperature hot water floor radiation heating system (referred to as floor heating).

[0003] PERT floor heating raw material is a medium-density polyethylene with very stable mechanical properties, which is copolymerized by metallocene catalysis of ethylene and octene monomers. Its unique ethylene main chain and octene short branched chain structure make it have the superior toughness, stress cracking resistance, low temperature impact resistance, outstanding long-term water pressure resistance of ethylene and the heat creep resistance of octene.

[0004] When laying the floor heating pipes, they are designed to have the maximum heat dissipation area, thereby ensuring a certain heating area. When the floor heating pipes are dissipating heat, the heat is dissipated 360°. A large part of the heat does not act on the ground at the top of the floor heating pipes, and the utilization rate of the hot water heat is low.

[0005] When laying floor heating pipes, the pipes need to be bent to achieve the maximum laying rate of the house. During the pipe bending process, for example, the floor heating pipes themselves have a certain strength, and they tend to return to their original shape after bending, which makes the laying of floor heating pipes more difficult, so a fixing method is needed. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a PERT floor heating pipe with resistance to thermal oxidation aging, which has the advantages of high hot water utilization rate and good fixing performance, and solves the problems raised by the above-mentioned background technology.

[0007] The utility model provides the following technical solution: a PERT floor heating pipe with resistance to thermal oxidation aging, comprising a pipe, an outer ring of the pipe is provided with an annular groove, an inner wall of the pipe is symmetrically provided with heat dissipation grooves, an inner wall of the pipe is located below the heat dissipation groove and is fixedly provided with a heat insulation tile, a partition cavity is provided inside the heat insulation tile, an outer ring of the annular groove is movably clamped with a clamping ring, a strip groove is provided in the middle of the clamping ring, and a fixing seat is fixedly connected to the bottom of the clamping ring.

[0008] Preferably, the annular grooves are arranged at equal intervals on the outer ring of the pipe, and the distance between adjacent annular grooves is selected by the user.

[0009] Preferably, a mark is provided on the surface of the pipe above the heat dissipation groove, and the mark is in a strip shape and is attached to the surface of the pipe.

[0010] Preferably, the interior of the pipeline is divided into two directions, the heat dissipation groove is located in the ground direction, the insulation tile is located in the underground direction, and the mark corresponds to the position of the heat dissipation groove.

[0011] Preferably, circular grooves are provided on both sides of the opening of the clamping ring, and the size of the circular grooves conforms to the size of fingers. The size of the circular grooves is selected by the user.

[0012] Preferably, a slot is provided on the top of the fixing seat, the clamping ring is located inside the slot, two sides of the slot are higher than the middle of the slot, and the two sides of the slot fit with the outer ring of the pipe.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The PERT floor heating pipe with resistance to thermal oxygen aging achieves high heat utilization by setting up heat dissipation grooves, insulation tiles, compartments and other structures. When heat enters the pipe, the heat is dissipated outwards through the heat dissipation grooves, and insulation tiles are installed on the symmetrical sides of the heat dissipation grooves. The insulation tiles reduce the heat dissipation outwards, so that the heat is dissipated through the heat dissipation groove side and retained through the insulation tile side, avoiding heat waste and achieving the effect of fixing heat and quickly dissipating heat.

[0015] 2. The PERT floor heating pipe with resistance to thermal oxidation aging can fix the position of the floor heating pipe through structures such as ring grooves, clamping rings, and fixing seats. The fixing seat is fixed on one side of the underground, and the pipe is clamped into the clamping ring through the opening of the clamping ring. After fixing, press the finger into the circular groove to break the auxiliary part of the clamping ring end from the clamping ring. When the floor heating pipe is buried at a later stage, the auxiliary part of the clamping ring is prevented from protruding, thereby fixing the floor heating pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The surface of the pipe 1 is provided with a mark above the heat dissipation groove 3. The mark is in the shape of a strip and fits on the surface of the pipe 1, which is convenient for users to identify the direction of the pipe and prevent users from placing the side with the heat dissipation groove 3 facing the ground. The outer ring of the annular groove 2 is movably connected with a clamping ring 6. Circular grooves are provided on both sides of the opening of the clamping ring 6. The size of the circular grooves conforms to the size of fingers. The size of the circular grooves is selected by users. A strip groove 7 is provided in the middle of the clamping ring 6. When the pipe enters the clamping ring 6, the opening of the clamping ring 6 is expanded by squeezing the two sides of the opening of the clamping ring 6 and then enters the clamping ring 6. When the pipe 1 and the clamping ring 6 are buried, the length of the clamping ring 6 is too long.

When the pipe 1 is heated, the temperature in the pipe is quickly dissipated to the outside through the heat dissipation groove 3, and the compartment 5 reduces the leakage of heating heat to the underground, making the temperature in the pipe 1 more concentrated.
