Description

Technical Field

[0001] This utility model relates to the field of HVAC duct insulation technology, and in particular to an HVAC duct insulation device. Background Technology

[0002] In the field of HVAC engineering, the insulation of piping systems is a key aspect of ensuring efficient heat transfer and reducing energy consumption. However, the connection flange and bolt areas at pipe joints have always been challenging areas for insulation due to their uneven structure and numerous gaps. Existing HVAC pipe insulation devices mostly use prefabricated insulation boards to directly cover the pipes. However, the raised structure of the connection flanges and bolts creates cavities between the insulation board and the pipe. These cavities cannot be effectively filled by conventional insulation boards and will also exacerbate heat loss due to air convection. At the same time, the installation of traditional insulation boards in the flange area requires a large gap to accommodate the bolts, which may further reduce the insulation sealing performance. In addition, if the insulation board is forcibly attached to the flange, it is easy for the insulation board to get stuck between the bolts, which may lead to difficulties in disassembly during subsequent maintenance. Utility Model Content

[0003] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a heating, ventilation and air conditioning (HVAC) pipe insulation device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A heating, ventilation, and air conditioning (HVAC) duct insulation device, comprising: A first insulation section and a second insulation section are connected to the pipe body, and the first insulation section and the second insulation section are connected together; The first insulation part includes a first insulation board and a first connecting plate, wherein the first connecting plate is fixedly connected to the first insulation board; The second insulation part includes a second insulation board and a second connecting plate, wherein the second connecting plate is fixedly connected to the second insulation board; The first and second insulation boards are connected to an insulation bladder, which is used for filling and insulation.

[0005] Preferably, a sealing gasket is fixedly connected to the inner sidewall of the first and second insulation boards, the insulation bag is fixedly connected to the sealing gasket, and the sealing gasket is in contact with the sidewall of the tube.

[0006] Preferably, the heat-insulating bag is a wear-resistant elastic airbag.

[0007] Preferably, both the first and second insulation boards are fixedly connected to an air supply pipe, which is connected to the insulation bag.

[0008] Furthermore, a pressure relief valve is fixedly connected to both the first and second insulation boards, and the pressure relief valve is connected to the insulation bag.

[0009] Furthermore, a fastening nut is fixedly connected to the bottom of the second connecting plate, and a fastening screw is connected to the first connecting plate, the fastening screw being threadedly connected to the fastening nut.

[0010] Compared with the prior art, this utility model provides a heating, ventilation and air conditioning (HVAC) pipe insulation device, which has the following beneficial effects: This invention, by setting a wear-resistant elastic insulation bladder inside the insulation board and combining it with an inert gas inflation operation, allows the insulation bladder to fully expand and fit into the cavity between the pipe body, sealing plate, and bolts, thoroughly filling the insulation dead corners formed by protruding structures such as flanges and bolts. This avoids heat loss caused by the gap between the traditional insulation board and the pipe, effectively improving the insulation sealing performance and insulation efficiency of the flange area.

[0011] During installation, this invention utilizes the expansion and compression of the insulation bladder to achieve a tight fit between the insulation board and the insulation bladder, and also helps the insulation bladder better fill the gaps. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0015] Reference Figures 1-4 A heating, ventilation, and air conditioning (HVAC) duct insulation device, comprising: A first insulation section and a second insulation section are connected to the pipe body 1, and the first insulation section is connected to the second insulation section; The two sets of pipe bodies 1 are connected by a connecting flange, and bolts 101 are connected to the connecting flange; The first insulation part includes a first insulation board 2 and a first connecting plate 201, with the first connecting plate 201 fixedly connected to the first insulation board 2; The second insulation part includes a second insulation board 3 and a second connecting plate 301, with the second connecting plate 301 fixedly connected to the second insulation board 3. The first insulation board 2 and the second insulation board 3 are connected to an insulation bladder 5, which is used for filling and insulation.

[0016] Both the first insulation plate 2 and the second insulation plate 3 are fixedly connected to an air supply pipe 6, which is connected to the insulation bag 5.

[0017] In practice, staff can fill the insulated bag 5 with argon or krypton through the gas filling tube 6.

[0018] Pressure relief valves 7 are fixedly connected to both the first insulation board 2 and the second insulation board 3, and the pressure relief valves 7 are connected to the insulation bag 5.

[0019] During routine maintenance, staff can check the connection and sealing between the first insulation board 2 and the second insulation board 3. If the sealing gasket 4 inside the two sets of insulation boards ages or wears down, resulting in poor connection and sealing between the two sets of insulation boards, staff can promptly disassemble the first insulation board 2 and the second insulation board 3, and replace the parts after inspection.

[0020] It should be noted that before maintenance and parts replacement, staff can manually open the pressure relief valve 7. At this time, the inert gas in the insulation bag 5 will be discharged through the pressure relief valve 7, which can effectively prevent the insulation bag 5 from getting stuck between the bolts 101 when the first insulation plate 2 or the second insulation plate 3 is disassembled, thus reducing the possibility of the insulation plate being difficult to disassemble.

[0021] It should also be noted that the air supply pipe 6 is connected to a commercially available one-way air intake valve, and the pressure relief valve 7 is a commercially available one-way pressure relief valve.

[0022] Sealing gaskets 4 are fixedly connected to the inner walls of the first insulation board 2 and the second insulation board 3. The insulation bag 5 is fixedly connected to the sealing gasket 4, and the sealing gasket 4 is in contact with the side wall of the tube body 1.

[0023] The heat preservation bladder 5 is a wear-resistant elastic air bladder; specifically, a closed-cell nitrile rubber air bladder that can be purchased on the market can be used.

[0024] It should be noted that the sealing gasket 4 is a commercially available silicone rubber gasket, and the first insulation board 2 and the second insulation board 3 are commercially available polyurethane boards.

[0025] The bottom of the second connecting plate 301 is fixedly connected to a fastening nut 3011, and the first connecting plate 201 is connected to a fastening screw 2011, which is threadedly connected to the fastening nut 3011.

[0026] During installation, the staff aligns the first insulation board 2 and the second insulation board 3 and pre-tightens the fastening screw 2011 onto the fastening nut 3011. When the first insulation board 2 and the second insulation board 3 are in contact, the staff fills the insulation bag 5 with inert gas through the gas supply pipe 6 for auxiliary insulation. After a certain amount of gas has been filled into the insulation bag 5, the staff stops feeding gas into the insulation bag 5 and uses tools to fully tighten the fastening screw 2011 again, so that the first insulation board 2 and the second insulation board 3 are tightly attached. At the same time, during the tightening of the fastening screw 2011, the first insulation board 2 and the second insulation board 3 will come closer to each other and squeeze the insulation bag 5 again, so that the insulation bag 5 can better fill and fit in the connection cavity between the tube body 1 and the sealing gasket 4.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
