Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of radiation air conditioning, in particular to a capillary repair tool. Background Art
[0002] Capillary radiation air conditioning is a water-collecting and water-distributing structure with the characteristics of large heat exchange area, thin wall, good thermal conductivity, uniform heat exchange and small water loss. It is an efficient heat exchanger. Capillary radiation air conditioning is thin, soft and light, so it is easy to install, the covering layer can be thin, and the paving area can be large. The installation thickness of the capillary grid is generally less than 5mm, and it can be flexibly laid on the ceiling, ground or wall, which is extremely convenient to install. During construction, due to improper operation or drilling holes in the wall, it is inevitable to touch the pre-buried capillary and cause damage. When the capillary is damaged, first close the water valve of the capillary grid, drain the water in the grid, and cut off the leaking branch pipe. The traditional repair method is to heat the two ports and squeeze the shear surface together to close this branch pipe. Although this repair method is simple, the seals at both ends are squeezed together. When the pressure in the pipe is too high, it is easy to cause the squeezed seals to collapse, resulting in ineffective repair. Utility Model Content

[0006] The hot melt holes are configured as blind holes of different specifications to fit capillaries of different specifications. The diameter of the blind hole is larger than the outer diameter of the capillary, which is 1 to 1.2 times of the outer diameter of the capillary, to ensure that the capillary can be smoothly inserted.

Five hot melt holes 4 and four screw holes 5 are opened on the outer surface of the pencil-shaped solid metal block; the heating body 1 is equivalent to a modified electric soldering iron. The specific manufacturing process of the above repair tool is as follows:
[0029] First, a solid metal block is processed into a tetrahedron structure, and then the edges of the tetrahedron are cut into faces, and then the top of the tetrahedron is cut into a cone, and finally a pencil-shaped heating head 2 is obtained. Figure 3 shown.
[0030] Hot melt holes 4 for capillaries are symmetrically arranged on the top and each surface near the top of the pencil-shaped heating head 2. The hot melt holes 4 are conical blind holes, and the diameter of the holes is larger than the outer diameter of the capillary to be repaired. A first blind hole 31 is opened at the bottom of the heating head 1, and then a second blind hole 32 is opened on the bottom surface of the first blind hole 31. The first blind hole 31 and the second blind hole 32 are coaxially connected, and the diameter 31 of the first blind hole is larger than the diameter 32 of the second blind hole; a screw hole 5 is opened on each of the four sides of the heating head 2, and the screw hole 4 is connected to the first blind hole 31.
[0031] The heating body 1 in this embodiment is modified from an existing electric soldering iron. The tip of the existing electric soldering iron is cut off, and then one-third of the heating shell is cut off, so that one end of the heating core extends out of the heating shell and is exposed to the outside, and the other end extends to the end of the electric soldering iron and is connected to the power cord, forming a new heating body 1.
[0032] like Figure 2As shown, the end of the heating core of the heating body 1 is inserted into the passage 3 of the heating head 2.
