Description
Technical field
The utility model is related to keep the temperature patch technology field more particularly to a kind of polyurethane scene to keep the temperature repaired mouth.
Background technology
Since the protection, heat preservation and erosion resistant coating of polyurethane heat-preserving pipeline main body are in factory by the prefabricated completion of special equipment
, the quality of protective layer and insulation antiseptic layer is reliable.Thus, determine the final corrosion-resistant thermal insulation of polyurethane heat-preserving pipeline after buried
The key of performance is protective layer repaired mouth, the i.e. quality of outer protection tube interface, (is sealed not at such as repaired mouth if mouthpiece quality is bad
Sternly, repaired mouth intensity is low etc.), thermal deformation can be generated in ditch or use under polyurethane heat-preserving pipeline, will appear at repaired mouth crackle or
Gap, underground water can penetrate into internal layer, destroy the heat-insulating property of polyurethane foam.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of polyurethane scene heat preservation repaired mouth.
The utility model adopts the following technical solution：
The junction of a kind of polyurethane scene heat preservation repaired mouth, two insulating tubes forms repaired mouth, is equipped at the repaired mouth position
Casing, described sleeve pipe include inner sleeve and outer tube, and the inner sleeve is equipped with hot melt adhesive layer, and the inner sleeve passes through the heat
Melt layer is bonded as one with insulating tube, and a cavity is formed between the inner sleeve and the outer tube, and the cavity is interior along circle
It is evenly arranged with several PVC protection pipes week, polyurethane foam is filled between two neighboring PVC protection pipes.
Preferably, reinforcement silk screen, the reinforcement silk screen and the PVC protection pipes phase are additionally provided on the inner wall of the cavity
It supports.
Preferably, the surface for reinforcing silk screen is equipped with anti-corrosion layer.
Preferably, resistance to compression layer is additionally provided in the cavity, the resistance to compression layer offsets with the hot melt adhesive layer, the resistance to compression layer
It is made of several trapezoid blocks.
Preferably, the trapezoid block is hollow structure, and polystyrene foam is filled in the trapezoid block.
The utility model has the advantages that:The polyurethane scene heat preservation repaired mouth of the utility model can be with insulating tube
Close connection not only has good heat insulation effect, while also having high intensity, prevents from being subject to crushing.

Specific implementation mode
As shown in Figure 1 to Figure 3, it is a kind of polyurethane scene heat preservation repaired mouth of the utility model, the connection of two insulating tubes
Place forms repaired mouth, and casing is equipped at repaired mouth position, and casing includes inner sleeve 1 and outer tube 2, and inner sleeve 1 is equipped with hot melt adhesive layer
3, inner sleeve is bonded as one by hot melt adhesive layer 3 with insulating tube, and a cavity 4, cavity 4 are formed between inner sleeve 1 and outer tube 2
Several PVC protection pipes 5 have inside been uniformly arranged along the circumference, polyurethane foam is filled between two neighboring PVC protection pipes 5.
Specifically, setting bilayer sleeve, and the PVC protection pipes 5 of annular array are equipped in bilayer sleeve, benefit can be improved
The bonding strength of mouth, and it is Nian Jie with insulating tube using hot melt adhesive layer 3, the fastness of connection can be improved so that heat insulation effect
More preferably.
It is additionally provided on the inner wall of cavity 4 and reinforces silk screen 6, reinforced silk screen 6 and PVC protection pipes 5 and offset, reinforce the table of silk screen 6
Face is equipped with anti-corrosion layer 7, can improve the intensity and corrosion resistance of casing.
Resistance to compression layer 8 is additionally provided in cavity 4, resistance to compression layer 8 offsets with hot melt adhesive layer 3, and resistance to compression layer 8 is made of several trapezoid blocks 9,
The intensity that casing is connect with insulating tube can be improved, insulating tube can be effectively prevent to be extruded.
In order to further increase heat insulation effect, trapezoid block 9 is hollow structure, and polystyrene foam is filled in trapezoid block 9.
The above are only specific embodiments of the present invention, but the technical characteristics of the utility model is not limited thereto.Appoint
How based on the utility model, for the technical problem for solving essentially identical, essentially identical technique effect is realized, it is made
Simple change, equivalent replacement or modification etc., are all covered by among the scope of protection of the utility model.
