Description
Technical Field
The utility model relates to a heating pipe joint insulation construction.
Background
In the fields of central heating, cooling, petroleum and natural gas and the like, heat preservation treatment is required to be carried out on a pipeline for medium conveying so as to ensure the temperature performance of the pipeline in the medium conveying process. The heat-insulating pipeline is prefabricated in a factory according to the length requirement, and then is constructed and installed on site, and a joint is formed at the joint of the two heat-insulating pipelines. The joint of the heat-insulating pipeline is an important part in a prefabricated direct-buried heat-insulating pipeline system, and the structural form and the construction method are very critical. In the whole heat preservation pipe network, the quality of joint installation will produce great influence to the life of whole pipe network.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a heating pipe joint insulation construction.
The utility model discloses a following technical scheme can realize.

The outer ends of the two ends of the heat insulation sleeve, which are in contact with the heat insulation layer, are fixed through a heat shrinkage belt.
The interior of the heat-insulating sleeve is filled with polyurethane foam.
The heat-insulating layer is made of polyurethane.
The heat-insulating sleeve is filled with polyurethane foam and then is in an ellipsoid shape.
The beneficial effects of the utility model reside in that: the heat preservation layer is formed at the pipeline joint through polyurethane foaming, and the heat preservation is carried out at the pipeline joint.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
in the figure: 1-a directly buried pipe, 2-a heat insulation sleeve, 3-a heat insulation layer, 4-a heat shrinkage belt, 5-a foaming inlet and 6-a foaming outlet.
Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
A thermal insulation structure of a heating pipe joint comprises a directly-buried pipe 1; the end joints of the two directly-buried pipes 1 are connected together in a butt joint mode, the outer ends of the directly-buried pipes 1 are covered with the heat insulation layer 3, the outer ends of the two directly-buried pipes 1 are connected in a sleeve mode through the heat insulation sleeve 2 after the end joints are connected, the two ends of the heat insulation sleeve 2 cover the heat insulation layer 3, and the heat insulation sleeve 2 is provided with the foaming inlet 5 and the foaming air outlet 6.
The outer ends of the two ends of the heat insulation sleeve 2, which are in contact with the heat insulation layer 3, are fixed through a heat shrinkage belt 4. Fix 2 both ends of insulation cover through pyrocondensation area, make to form between 2 both ends of insulation cover and the heat preservation of pipeline outer wall sealed, make the polyurethane foam in insulation cover 2 can the tamp and fill, realize the heat preservation effect.
The interior of the heat-insulating sleeve 2 is filled with polyurethane foam.
The heat-insulating layer 3 is made of polyurethane.
The heat insulation sleeve 2 is filled with polyurethane foam and then is in an ellipsoid shape.
The polyurethane heat-insulating layer, the working pipe and the high-density polyethylene are bonded together to form a firm whole body, so that the connection strength of the pipeline joint is enhanced.
