Abstract
The utility model discloses a fibrous thermal insulation tube shell made of celluloses. The fibrous thermal insulation tube shell made of celluloses is composed of an upper half tube shell and a lower half tube shell, wherein, one side of the upper half tube shell is provided with inner steps, and the other side of the upper half tube shell is provided with outer steps. One side of the corresponding lower half tube shell is provided with the outer steps, and the other side of the lower half tube shell is provided with the inner steps. When the upper half tube shell is combined with the lower half tube shell, the inner steps of the upper half tube shell are fit with the outer steps of the lower half tube shell, and the outer steps of the upper half tube shell are fit with the inner steps of the lower half tube shell. The utility model has the advantages of convenient manufacture and installation, high sealing effect, favorable heat insulating effect, fire resistance, no pollution, etc.
Description
The utility model relates to a kind of cellulose fiber thermal-insulating pipe case.
At present, existing thermal-insulating pipe case mainly contains with materials such as glass fibre, mineral wool, foamed plastics and makes.The thermal-insulating pipe case that these materials are made, its thermal conductivity is higher, and heat insulation effect is undesirable; Or construction inconvenience, as the foamed plastics thermal-insulating pipe case, must be bonding during construction with the pitch that has melted, or wrap up with weave cloth; Have in producing each construction, environment is polluted, human body is caused discomfort, as the spun-glass insulation shell.In addition, also there is the problem of fire-fighting aspect in the thermal-insulating pipe case that these materials are made.When meeting high temperature, can distribute and have irritating toxicity flue gas.Structurally, existing thermal-insulating pipe case mainly contains two kinds, and the one, cylindrical, axially open a breaking joint, during installation, thermal-insulating pipe case opened, wrap pipe after, sticking and the breaking joint place with the lead foil binding tape, the 2nd, by the synthetic pipe shape of two halfs, tackiness agent is bonding during installation.Each mating face of these structures is the plane, does not note slightly during installation, can make the existing slit of conducting oneself in society, mating face, directly influences heat insulation effect.
Being of the purpose of this utility model provides good, easy for installation, the difficult combustion of a kind of insulation effect, cellulose fiber thermal-insulating pipe case free from environmental pollution.
For achieving the above object, cellulose fiber thermal insulation pipe of the present utility model is made up of first shell and second shell, one side first shell be provided with interior step, another side is provided with outer step; One side of corresponding second shell is provided with outer step, and another side is provided with interior step, and when first shell and second shell synthesized, the interior step of first shell and the outer step of second shell matched, and the outer step of first shell and the interior step of second shell match.
The further improvement project of the utility model is: the axial end at first shell and second shell is respectively equipped with the boss rank, the other end is respectively equipped with the concave station rank, when first shell and second shell were synthetic, the recessed circular groove that its concave station rank surround was slightly larger than the dome that will is enclosed on the boss rank.
After adopting such structure, make production and processing comparatively convenient, promptly the mode of structure of first shell and second shell makes when installing and brings convenience, fast and good sealing effect, and insulation effect is good.
Fig. 1 is the structural representation of the concrete a kind of embodiment of the utility model.
Cellulose fiber thermal-insulating pipe case as shown in Figure 1 is made up of first shell 1 and second shell 2, one side first shell 1 be provided with interior step 11, another side is provided with outer step 12; One side of corresponding second shell 2 is provided with outer step 21, another side is provided with interior step 22, when first shell 1 synthesized with second shell 2, the interior step 11 of first shell 1 matched with the outer step 21 of second shell 2, and the outer step 12 of first shell 1 matches with the interior step 22 of second shell 2; First shell 1 is respectively equipped with boss rank 13,23 with an axial end of second shell 2, the other end is respectively equipped with concave station rank 14,24, when first shell 1 synthesized with second shell 2, the recessed circular groove that its concave station rank 14,24 surround was slightly larger than the dome that boss rank 13,23 surround.Make when making, utilize cellulose material spraying machine and glue material spraying machine, mould is made two semi-involutions and is become tubulose, its radially involutory surface be provided with the concave, convex step, involutoryly coincide mutually; Axially both ends of the surface are established boss rank for one, and the other end is established concave station rank, and concavo-convex being bonded with each other during the multistage combination reaches the better seal effect.
