Two-section type tee joint heat-preserving bend accessory

Abstract

The invention discloses a two-section type tee joint heat-preserving bend accessory. The two-section type tee joint heat-preserving bend accessory is used for being connected among three to-be-connected heat-preserving pipes, and comprises an upper tee joint pipe shell, a lower tee joint pipe shell, an inner tee joint pipe and a foaming agent. Outer pipes and the foaming agent are removed throughthe connecting ends of the three to-be-connected heat-preserving pipes, inner pipes are exposed, the inner tee joint pipe is arranged on the three inner pipes in a communicated manner, connecting bases shaped like a Chinese character 'hui' are symmetrically arranged at the positions of three-end connection ports of the upper tee joint pipe shell and the lower tee joint pipe shell, the lower tee joint pipe shell and the upper tee joint pipe shell are cooperatively connected and arranged on the outer pipes, an injection hole is formed in the middle position of the upper tee joint pipe shell, theupper tee joint pipe shell and the lower tee joint pipe shell are connected together in the manner that screws penetrate through the connecting bases shaped like the Chinese character 'hui', and theportions among the inner straight pipes, the upper tee joint pipe shell and the lower tee joint pipe shell are filled with the foaming agent through the injection hole. The structure is simple, and the two-section type tee joint heat-preserving bend accessory can be used for connection among the heat-preserving pipes, and can protect water pipes at the turning joints just like the heat-preservingpipes.

Description

technical field [0001] The invention relates to the technical field of thermal insulation pipe connection fittings, in particular to a two-petal three-way thermal insulation elbow fitting. Background technique [0002] Application number: 201510001991.X Invention introduces a thermal insulation pipe, including a straight-through inner tube of the thermal insulation tube, and a thermal insulation cavity that wraps the outer wall of the inner tube of the thermal insulation tube. The thermal insulation cavity is located in a closed shell. The thermal cavity is vacuum or filled with heat insulating medium. Further, it also includes the outer pipe of the heat preservation pipe, the inner diameter of the outer pipe of the heat preservation pipe is larger than the outer diameter of the inner pipe of the heat preservation pipe, and the two ends of the outer pipe of the heat preservation pipe are closing places, and the closing places are sealed and connected to the outer wall of the...

Problems solved by technology

[0003] Existing pipelines are generally wrapped with thermal insulation cotton on the outside of the pipeline or at the joints between the pipelines to insulate the pipeline. This external insulation method is easy to fall off, weathered for a long time, and the insulation effect will be uneven, easy to Let the water pipe burst, especially if the length is not enough, the connection of multiple water pipes is often easily overlooked. Under the impact of the internal water flow and uneven heating, it is more likely to burst, so a convenient installation is required. Insulation elbow fittings with good insulation effect to meet the connection needs of insufficient insulation water pipe length
