Description

Technical Field

[0001] This utility model relates to the field of PE gas pipeline technology, specifically to a PE gas pipeline insulation structure. Background Technology

[0002] Due to the environmental impact of PE gas pipelines, they need to be insulated. The usual method of insulation is to wrap insulation material around the outside of the PE gas pipeline, ensuring that the insulation material is in close contact with the PE gas pipeline.

[0003] However, to facilitate the connection of PE gas pipelines, an insulation layer is usually not installed at the top of the PE gas pipeline. After the PE gas pipeline is connected, the insulation layer needs to be reinstalled. Therefore, we propose a PE gas pipeline insulation structure to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide a PE gas pipeline insulation structure to solve the problem mentioned in the background art that the insulation layer needs to be reinstalled after the PE gas pipeline is connected.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PE gas pipeline insulation structure, comprising a PE gas pipe body, an insulation layer disposed on the outer side of the PE gas pipe body, and a first protective sleeve disposed on the outer side of the insulation layer, the insulation layer comprising a foam insulation layer, an inner long-filament fiber insulation layer, an aluminum foil insulation layer, and an outer long-filament fiber insulation layer, the foam insulation layer being disposed on the outer side of the PE gas pipe body, the inner long-filament fiber insulation layer being disposed on the outer side of the foam insulation layer, the aluminum foil insulation layer being disposed on the outer side of the inner long-filament fiber insulation layer, and the outer long-filament fiber insulation layer being disposed on the outer side of the aluminum foil insulation layer, further comprising:

[0006] The system comprises a first movable insulation layer, a second movable insulation layer, and a second protective sleeve. The first and second movable insulation layers are disposed at the joint of the PE gas pipe body, and the second protective sleeve is disposed on the outside of the first and second movable insulation layers. The outer surfaces of the first and second movable insulation layers are both connected to the first protective sleeve.

[0007] Preferably, there are two first movable insulation layers and one second movable insulation layer, and the insulation layers of both the first and second movable insulation layers are the same as the insulation layer of the insulation layer.

[0008] Preferably, the first movable insulation layer and the second movable insulation layer wrap around the PE gas pipe body, and the arc length of the first movable insulation layer is smaller than the arc length of the second movable insulation layer.

[0009] Preferably, the first movable insulation layer and the second movable insulation layer are connected by rivets, and the rivets have a concave structure, and the outer sides of the first movable insulation layer and the second movable insulation layer are wrapped with tape.

[0010] Preferably, the second protective sleeve has a cylindrical structure and is made of polyethylene hot melt adhesive.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In this PE gas pipeline insulation structure, a second protective sleeve is fitted onto a PE gas pipe body. After the two PE gas pipe bodies are heat-fused together, the first and second movable insulation layers are wrapped around the outside of the PE gas pipe body, so that the left and right ends of the first and second movable insulation layers are respectively attached to the insulation layers on the left and right sides. The first and second movable insulation layers are then connected by rivets, and then the first and second movable insulation layers are wrapped and fixed by tape. By sliding the second protective sleeve, the second protective sleeve moves to the first and second movable insulation layers. By heating with a blowtorch, the second protective sleeve shrinks due to heat, sealing the PE gas pipe bodies on the left and right sides, thereby insulating the joint of the PE gas pipe body. The insulation layer, the first movable insulation layer, and the second movable insulation layer are all composed of a foam insulation layer, an inner long-fiber insulation layer, an aluminum foil insulation layer, and an outer long-fiber insulation layer, which increases the insulation effect.

The first and second movable insulation layers 4 and 5 are then connected using rivets 7, and finally secured with tape 8. The second protective sleeve 6 can be slid to... Figure 1 As shown, the second protective sleeve 6 moves to the first movable insulation layer 4 and the second movable insulation layer 5. By heating with a torch, the second protective sleeve 6 shrinks due to heat, sealing the PE gas pipe body 1 on both sides, thereby insulating the joint of the PE gas pipe body 1. The insulation layer 2, the first movable insulation layer 4 and the second movable insulation layer 5 are all composed of a foam insulation layer 201, an inner long filament fiber insulation layer 202, an aluminum foil insulation layer 203 and an outer long filament fiber insulation layer 204, which increases the insulation effect.
