Description

Technical Field

[0001] The utility model belongs to the technical field of HVAC engineering, and more specifically, particularly relates to a heat-insulating HVAC pipe. Background Art

[0002] HVAC pipes refer to various pipes used in HVAC systems. These pipes are used to transport materials such as air, cold water, hot water, steam, and refrigerants to achieve heating, ventilation, and air conditioning functions inside buildings.

[0003] When connecting some HVAC pipes nowadays, two HVAC pipes are directly aligned and connected together through flanges, which requires workers to frequently adjust the positions of the two HVAC pipes so that the two HVAC pipes can remain in a parallel position, resulting in low work efficiency. In addition, as the warm air circulates in the HVAC pipe, part of the heat will be dissipated along the pipe wall of the HVAC pipe and transferred to the insulation sleeve. At this time, under the action of thermal expansion and contraction, the insulation sleeve is prone to expansion and deformation due to the increase in heat. When the heating supply in the HVAC pipe is stopped and the temperature drops, after long-term temperature cycles, the insulation sleeve is prone to multiple deformations and cannot fit well with the outer wall of the HVAC pipe, which leads to a decrease in thermal insulation performance.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an insulated HVAC pipe is provided to achieve a more practical purpose. Utility Model Content

[0007] Furthermore, the size of the annular connecting block matches the size of the annular connecting groove.

[0008] Furthermore, the sizes of the upper mounting shell and the lower mounting shell match.

[0011] Furthermore, a moisture-proof layer is provided inside the HVAC pipe body.

[0012] Furthermore, the surface of the HVAC pipe body is provided with a galvanized layer.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The heat-insulating HVAC pipe of the utility model cooperates with the HVAC pipe body, the annular connecting groove, the annular connecting block and the flange, so that when splicing two HVAC pipe bodies, the two HVAC pipe bodies can be quickly aligned and spliced ​​together through the engagement of the annular connecting groove and the annular connecting block, thereby improving the work efficiency when installing the HVAC pipe body.

[0025] Example:

[0026] As attached Figure 1 To Attachment Figure 4 As shown:

[0027] The utility model provides a heat-insulating HVAC pipe, comprising a HVAC pipe body 1, one end of the HVAC pipe body 1 is provided with an annular connecting groove 2, the other end of the HVAC pipe body 1 is provided with an annular connecting block 3, both ends of the HVAC pipe body 1 are provided with flanges 4, the top end of the HVAC pipe body 1 is provided with an upper mounting shell 5, the bottom end of the HVAC pipe body 1 is provided with a lower mounting shell 6, a plurality of compression springs 7 are provided on the inner sides of the upper mounting shell 5 and the lower mounting shell 6, an arc-shaped mounting plate 8 is provided on the other end of the plurality of compression springs 7, and a heat-insulating sleeve 9 is provided on the inner side of the arc-shaped mounting plate 8.

[0028] Among them, the size of the annular connecting block 3 matches the size of the annular connecting groove 2. When splicing two HVAC pipe bodies 1, the staff aligns the position of the annular connecting block 3 on one side of the second HVAC pipe body 1 with the position of the annular connecting groove 2 on one side of the first HVAC pipe body 1, and then inserts the annular connecting block 3 into the annular connecting groove 2 and rotates the second HVAC pipe body 1 to align the flanges 4 on the two HVAC pipe bodies 1. After alignment, the flanges 4 are locked and fixed to complete the splicing.

[0029] The sizes of the upper mounting shell 5 and the lower mounting shell 6 match each other, so that the upper mounting shell 5 and the lower mounting shell 6 can fit together well and protect the internal HVAC pipe body 1.

[0030] Among them, the inner side of the insulation sleeve 9 is in close contact with the outer wall of the HVAC pipe body 1, and the insulation sleeve 9 can reduce the heat loss of the HVAC pipe body 1 when it is in use. When the insulation sleeve 9 expands and deforms due to the increase in temperature, the insulation sleeve 9 squeezes the arc-shaped mounting plate 8, so that the arc-shaped mounting plate 8 moves away from the HVAC pipe body 1. When the temperature of the insulation sleeve 9 decreases and stops expanding or contracts, the compression spring 7 rebounds and squeezes the insulation sleeve 9 through the arc-shaped mounting plate 8, so that the insulation sleeve 9 can fit better on the surface of the HVAC pipe body 1, so that the insulation sleeve 9 can still maintain a good insulation effect after long-term use.

[0031] Among them, a number of mounting holes 10 are provided on both sides of the upper mounting shell 5 and the lower mounting shell 6 at mutually symmetrical positions, which are convenient for fixing the upper mounting shell 5 and the lower mounting shell 6 on the surface of the HVAC pipe body 1 to protect the HVAC pipe body 1. At the same time, when the HVAC pipe body 1 needs to be inspected, the upper mounting shell 5 and the lower mounting shell 6 can be quickly disassembled.

[0032] Among them, a moisture-proof layer 11 is provided inside the HVAC pipe body 1. The material of the moisture-proof layer 11 is polyethylene. Polyethylene has a very low water vapor permeability and can effectively prevent moisture from passing through. Polyethylene also has good flexibility and certain mechanical strength, and can adapt to application requirements of different shapes and surfaces, and can withstand certain mechanical pressure and stretching.

[0033] Among them, the surface of the HVAC pipe body 1 is provided with a galvanized layer 12. HVAC pipes are often exposed to humid or chemical environments and are prone to corrosion. The galvanized layer 12 can effectively prevent the HVAC pipe body 1 from direct contact with air, moisture and other chemicals, reduce the occurrence of oxidation and corrosion, greatly extend the service life of the HVAC pipe body 1, and reduce the frequency of replacement and maintenance.

[0034] Working principle of this embodiment: when splicing two HVAC pipe bodies 1, the staff first aligns the position of the annular connecting block 3 on one side of the second HVAC pipe body 1 with the position of the annular connecting groove 2 on one side of the first HVAC pipe body 1, and then inserts the annular connecting block 3 into the annular connecting groove 2 and rotates the second HVAC pipe body 1 to align the flanges 4 on the two HVAC pipe bodies 1. After alignment, the flanges 4 are locked and fixed to complete the splicing. When the heat-insulating HVAC pipe is in use, the heat-insulating sleeve 9 can reduce the heat loss of the HVAC pipe body 1 during use. When the heat-insulating sleeve 9 expands and deforms due to temperature increase, the heat-insulating sleeve 9 squeezes the arc-shaped mounting plate 8 to move the arc-shaped mounting plate 8 away from the HVAC pipe body 1. When the temperature of the heat-insulating sleeve 9 decreases and stops expanding or contracts, the compression spring 7 rebounds through the arc-shaped mounting plate The mounting plate 8 squeezes the insulation sleeve 9 so that the insulation sleeve 9 can fit well on the surface of the HVAC pipe body 1, so that the insulation sleeve 9 can still maintain a good insulation effect after long-term use. Among them, the interior of the HVAC pipe body 1 is provided with a moisture-proof layer 11, and the material of the moisture-proof layer 11 is polyethylene. Polyethylene has a very low water vapor permeability and can effectively prevent moisture from passing through. Polyethylene has good flexibility and a certain mechanical strength, and can adapt to application requirements of different shapes and surfaces. At the same time, it can withstand a certain mechanical pressure and stretching. The surface of the HVAC pipe body 1 is provided with a galvanized layer 12. The galvanized layer 12 can effectively prevent the HVAC pipe body 1 from direct contact with air, moisture and other chemicals, reduce the occurrence of oxidation and corrosion, greatly extend the service life of the HVAC pipe body 1, and reduce the frequency of replacement and maintenance.
