Description

Technical Field

[0001] This utility model belongs to the field of HVAC pipe insulation, and specifically relates to an HVAC pipe insulation device. Background Technology

[0002] HVAC ducts are used to transport gases or liquids at a certain temperature to achieve a heating effect. In severe winters, ice easily forms on the ducts, and ducts exposed to the ground are more prone to heat exchange with the outside environment, leading to icing on the outside and increased risk of pipe cracking. Chinese patent CN 115681681A discloses a duct support device for HVAC equipment. It includes two semi-annular fixed shells, two semi-annular insulating shells, and a connecting mechanism. The two fixed shells, when fastened together, form a cylindrical support shell, and the two insulating shells, when fastened together, form a cylindrical insulation body. The width of the insulating shell is greater than the width of the fixed shell. The fixed shell and the insulating shell are connected by a threaded structure. The connecting mechanism is used to fix the fixed shell to the wall, thereby fixing the duct to the wall. This invention uses two insulating shells instead of traditional insulation cotton to insulate the fixed parts of the duct, while other parts of the duct are insulated with traditional insulation cotton. The fixing process does not damage the insulation cotton, ensuring effective insulation of the duct.

[0003] However, this technical solution has the drawbacks of inconvenience in insulating exposed pipes and inconvenience in replacing the insulation cotton of connecting pipes. Utility Model Content

Detailed Implementation

[0024] The heating, ventilation, and air conditioning (HVAC) duct insulation device of this utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] This embodiment discloses a heating, ventilation, and air conditioning (HVAC) pipe insulation device, such as... Figure 1-6 As shown, it includes an exposed pipe, with connecting pipes welded to both sides of the exposed pipe, and a heating element 5 installed in the middle of the exposed pipe for heating and heat preservation of the exposed pipe;

[0027] The exposed pipe includes an exposed inner steel pipe 15 and an exposed outer steel pipe 1, with a first gap between the exposed inner steel pipe 15 and the exposed outer steel pipe 1;

[0028] The connecting pipe includes an outer steel pipe 2 and an inner steel pipe 3. The inner steel pipe 3 is inserted inside the outer steel pipe 2, and a second gap is provided between the inner steel pipe 3 and the outer steel pipe 2.

[0029] Both the first and second gaps are filled with insulating cotton.

[0030] The heating component 5 includes an annular sleeve 16 attached to the inner wall of an exposed inner steel pipe 15. A ceramic heating element 17 is installed inside the annular sleeve 16. Two electrode rods 12 are connected to the upper side of the ceramic heating element 17. The annular sleeve 16 is fixedly installed to the exposed inner steel pipe 15. A support sleeve 11 is electrically connected to the upper side of the electrode rods 12. A threaded insulating rod 14 is fixedly installed on the exposed inner steel pipe 15. An adjusting threaded rod 9 is threaded to the upper outer side of the threaded insulating rod 14. An insulating square rod 13 is fixedly installed on the upper side of the adjusting threaded rod 9. The support sleeve 11 passes through the threaded insulating rod 14 and extends to the upper side of the threaded insulating rod 14. An adjusting handle 6 is inserted into the insulating square rod 13. A wire 8 is fixedly passed through the inner side of the insulating square rod 13. A conductive plate 10 is fixedly connected to the lower side of the wire 8. Annular electrode plates are fixedly connected to the center and non-center positions of the conductive plate 10. The two electrode plates correspond to the two electrodes respectively. Directly above rod 12, in the severe winter, ice easily forms on the pipes. Pipes exposed to the ground are more prone to heat exchange with the outside, causing ice to form on the outside of the pipes, which can easily lead to pipe cracking. By rotating the adjusting handle 6, the adjusting handle 6 drives the insulating square rod 13 to rotate, which in turn drives the adjusting threaded rod 9 to rotate. Since the adjusting threaded rod 9 is threadedly connected to the threaded insulating rod 14, it drives the conductive plate 10 to move closer to the support sleeve rod 11, thereby making the two electrode plates on the conductive plate 10 electrically connected to the wiring electrode rod 12 that works with each other, thus making the ceramic heating element 17 work, thereby heating the exposed inner pipe and keeping the exposed inner steel pipe 15 at a constant temperature. A fixing plate 24 is fixedly connected to the lower side of the annular sleeve plate 16. The fixing plate 24 is fixedly set to the inner wall of the exposed inner steel pipe 15. The annular sleeve plate 16 at this location is made of metal and has the function of heat conduction.

[0031] Multiple evenly distributed auxiliary pads 7 are fixedly installed on the outer circumference of the inner steel pipe 3 to assist in supporting the outer steel pipe 2 on the outside of the inner steel pipe 3.

[0032] The outer steel pipe 2 includes multiple arc-shaped pieces arranged in a ring around the inner steel pipe 3. The arc-shaped pieces are attached to the auxiliary pads 7. The multiple arc-shaped pieces are arranged in a circle, and the outer side of the multiple auxiliary pads 7 is equipped with binding components 4 to fix the position of the multiple auxiliary pads 7 on the inner steel pipe 3.

[0033] The auxiliary pad 7 has symmetrical main oblique angles on both sides, and the arc-shaped piece has secondary oblique angles on both sides that match the main oblique angles. This makes it easy for the secondary oblique angles on both sides of the arc-shaped piece to contact the main oblique angles, thus sealing the second gap. Then, the binding component 4 is used to fix the position of multiple cooperating arc-shaped pieces on the auxiliary pad 7, which also makes it easy to replace the insulation cotton later.

[0034] The auxiliary pad 7 has symmetrical placement grooves on both sides, and a sealing rubber ring 22 is installed in the placement groove. The sealing rubber ring 22 has a sealing function to prevent rainwater from seeping into the insulation cotton of the second gap.

[0035] The restraint component 4 includes two arc-shaped clamping rods 18 hinged on one side, and an extension plate 19 fixedly installed on the other side of the arc-shaped clamping rods 18. A locking screw 20 is hinged on the upper extension plate 19, and a slot is opened in the middle of the lower extension plate 19. The locking screw 20 passes through the slot and is threadedly connected to an adjusting cap 21. The two arc-shaped clamping rods 18 are sleeved on the outside of the arc-shaped pieces, and then the adjusting cap 21 is rotated in the forward direction, which drives the locking screw 20 to rotate, thereby quickly fixing the position of multiple arc-shaped pieces on the auxiliary pad 7.

[0036] When this utility model is in use, after the outside temperature drops below zero, the wires connected to the external power supply equipment and the conductor 8 are electrically connected. By rotating the adjustment handle 6, the adjustment handle 6 drives the insulating square rod 13 to rotate, and the insulating square rod 13 drives the adjustment threaded rod 9 to rotate. Due to the threaded connection between the adjustment threaded rod 9 and the threaded insulating rod 14, the conductive plate 10 is moved closer to the support sleeve rod 11, thereby making the two electrode plates on the conductive plate 10 electrically connected with the wiring electrode rod 12 that cooperates with it, so that the ceramic heating element 17 works and heats the exposed inner pipe, so that the exposed inner steel pipe 15 always maintains a constant temperature. When it is necessary to replace the insulation cotton of the connecting pipe, by rotating the adjustment cap 21 in the reverse direction, the locking screw 20 is driven to rotate, thereby releasing the binding component 4 from fixing the multiple arc-shaped pieces. After replacing the insulation cotton, the multiple arc-shaped pieces are installed on the auxiliary pad 7. Similarly, by rotating the adjustment cap 21 in the forward direction, the binding component 4 quickly fixes the position of the arc-shaped pieces on the auxiliary pad 7.
