Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of HVAC pipes, in particular to an energy-saving HVAC pipe for heating equipment. Background Art
[0002] A heating equipment is a device that uses air, steam or hot water as a heat medium for heating. When installing heating equipment, pipes are required for pipeline laying to transport the heat medium. At the same time, with the rapid development of society and the continuous improvement of manufacturing levels, energy-saving materials have been widely used, and energy-saving pipes have emerged as the times require. Usually, energy-saving materials are used to manufacture HVAC pipes.
[0003] After retrieval, the Chinese patent document with the publication number of CN218895145U discloses an HVAC pipe with energy-saving effects, including a pipe. Chutes are opened at both ends of the pipe. The chutes are rotatably connected to sliding rings. A groove is opened inside the sliding ring. One end of a scraping knife is fixedly connected to the side wall of the sliding ring. The other end of the scraping knife is fixedly connected to the side wall of another sliding ring. An anti-heat-loss mechanism is detachably installed inside the groove, which includes a heat-insulating layer. The upper surface of the heat-insulating layer is fixedly connected to a vacuum heat-insulating layer. The upper surface of the vacuum heat-insulating layer is fixedly connected to a wear-resistant outer shell. The top of the scraping knife is hinged to a semi-circular cover plate. For this HVAC pipe with energy-saving effects, by setting the anti-heat-loss mechanism, the heat loss of the pipe can be reduced, achieving an energy-saving effect. At the same time, in cooperation with the sliding ring and the groove, the anti-heat-loss mechanism can be quickly replaced, extending the service life of the device. However, in this solution, the pipes are butt-jointed by flange rings, and the flange ring butt-joint requires manual alignment, so the assembly is relatively cumbersome, resulting in slow assembly efficiency.

[0023] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0024] Referring to Figures 1 - 3 , an embodiment provided by the present utility model: an energy-saving HVAC pipeline for heating equipment, including a pipeline body 1. One end of the pipeline body 1 is fixedly connected with an inner connecting pipe 2. A positioning rod 3 is fixedly connected inside the inner connecting pipe 2. Flange rings 4 are fixedly connected to both ends of the pipeline body 1. A fixing bolt 5 is threadedly connected inside the flange ring 4. The other end of the pipeline body 1 is fixedly connected with an outer connecting pipe 6. A connecting seat 7 is slidably connected inside the outer connecting pipe 6. A rotating shaft 8 is rotatably connected inside the connecting seat 7. Both ends of the rotating shaft 8 are slidably connected inside the outer connecting pipe 6. An active rod 9 is fixedly connected to the outer wall of the rotating shaft 8. A push plate 10 is rotatably connected to the outer wall of the active rod 9. A clamping block 11 is fixedly connected to the outer wall of the push plate 10. An inserting block 12 is slidably connected to the outer wall of the clamping block 11. A first spring 13 is arranged inside the inserting block 12. One end of the first spring 13 is fixedly connected to the outer wall of the push plate 10, and the other end of the first spring 13 is fixedly connected to the inside of the inserting block 12. A pull rod 14 is fixedly connected to the outer wall of the connecting seat 7. A second spring 15 is sleeved on the outer wall of the pull rod 14. A buffer assembly is arranged inside the pipeline body 1;
[0025] Specifically, first, insert the positioning rod 3 on one pipeline body 1 into the inside of one end of another pipeline body 1. This step enables the positioning rod 3 to directly align the flange rings 4 on the two pipeline bodies 1, thus saving the laborious manual docking process. Next, rotate the fixing bolt 5 to fix the two flange rings 4. The function of this step is to initially connect the two pipeline bodies 1 and lay a foundation for subsequent operations. Then, while the positioning rod 3 slides into the pipeline body 1, the inserting block 12 inside the outer connecting pipe 6 will slide inside another outer connecting pipe 6. This design enables another outer connecting pipe 6 to push the clamping block 11, and then the push plate 10 squeezes the first spring 13. There are protrusions on the outer wall of the push plate 10 to limit the position of the push plate 10. The advantage of this design is that the inserting block 12 can slide into another outer connecting pipe 6. When the clamping block 11 slides into the corresponding hole inside another outer connecting pipe 6, the second spring 15 will push the connecting seat 7 by its elastic force. And the first spring 13 will push the push plate 10, thereby driving the active rod 9 to expand and fix the clamping block 11 inside another outer connecting pipe 6. Thus, different pipelines can be stably assembled and there is no need to align the reserved holes of the flange rings one by one, improving the stability of the HVAC pipeline and ensuring the smooth flow of air.
[0026] Refer to Figure 4 , the buffer assembly includes a buffer plate 16, and the outer wall of the buffer plate 16 is fixedly connected to the inside of the pipe body 1;
[0027] Specifically, by fixing the buffer plate 16 inside the pipe body 1, on the one hand, the buffer plate 16 can guide the direction of the air flow, and on the other hand, the buffer plate 16 can reduce the impact force of the air flow on the adjusting component, so as to achieve the effect of buffering the air flow.
[0028] Refer to Figures 4 - 5 , one end of the second spring 15 is fixedly connected to the outer wall of the connecting seat 7, and the other end of the second spring 15 is fixedly connected to the inside of the outer connecting pipe 6; a rotary handle 17 is rotatably connected to the inside of the pipe body 1, and a limiting plate 18 is rotatably connected to the outer wall of the rotary handle 17; a main bevel gear 19 is fixedly connected to the outer wall of the rotary handle 17, and a straight rod 20 is rotatably connected to the inside of the limiting plate 18; a sub-bevel gear 21 is fixedly connected to the outer wall of the straight rod 20, and the outer wall of the main bevel gear 19 meshes with the outer wall of the sub-bevel gear 21; a sliding sleeve 22 is rotatably connected to the outer wall of the straight rod 20, the outer wall of the sliding sleeve 22 is fixedly connected to the inside of the pipe body 1, a baffle 24 is slidably connected to the inside of the sliding sleeve 22, and the outer wall of the baffle 24 is fixedly connected to the outer wall of the straight rod 20; a sealing plug 25 is fixedly connected to the outer wall of the baffle 24, a fixing frame 23 is rotatably connected to the outer wall of the straight rod 20, and the outer wall of the fixing frame 23 is fixedly connected to the inside of the pipe body 1;
[0029] Specifically, just rotate the rotary handle 17 to drive the main bevel gear 19 to rotate. The main bevel gear 19 meshes with the sub-bevel gear 21 to transmit power, and through the setting of the limiting plate 18, the stability and safety of the main bevel gear 19 and the sub-bevel gear 21 during rotation can be ensured. In addition, the sub-bevel gear 21 drives the straight rod 20 to rotate, so as to realize the regulation of the baffle 24. The baffle 24 can rotate inside the sliding sleeve 22 to adjust the gap between it and the sliding sleeve 22, so as to achieve the purpose of regulating the air flow speed and flow rate. The fixing frame 23 limits the straight rod 20 to ensure the stability of the regulation process. The design of the sealing plug 25 can effectively seal the edges of the sliding sleeve 22 and the baffle 24 to prevent gas leakage and improve the sealing performance of the system. This design not only improves the practicability of the HVAC pipeline, avoids the waste of excess heating, but also reduces energy consumption, which is conducive to achieving the goal of green buildings. In short, it not only achieves the purpose of high efficiency, energy saving and environmental protection, but also is easy to install and maintain because of its simple structure.
[0030] Working principle: When the pipeline needs to be connected and assembled, the positioning rod 3 on one pipeline body 1 is inserted into the inner end of another pipeline body 1, so that the positioning rod 3 can directly align the flange rings 4 on the two pipeline bodies 1, thus saving the laborious manual docking process. Then, the two flange rings 4 are fixed by rotating the fixing bolts 5, and thus the two pipeline bodies 1 are preliminarily connected. While the positioning rod 3 slides into the pipeline body 1, the insertion block 12 inside the outer connecting pipe 6 will slide inside another outer connecting pipe 6, so that the other outer connecting pipe 6 will push the clamping block 11, and then the push plate 10 will squeeze the first spring 13. The outer wall of the push plate 10 is provided with protrusions to limit the position of the push plate 10, so that the clamping block 11 can contract, and thus the insertion block 12 can slide into another outer connecting pipe 6. When the clamping block 11 slides into the corresponding hole inside another outer connecting pipe 6, the second spring 15 will push the connecting seat 7 by its elastic force, and the first spring 13 will push the push plate 10, and then drive the movable rod 9 to expand, fixing the clamping block 11 inside another outer connecting pipe 6, so as to achieve the effect of stably assembling different pipelines and eliminating the need to align the reserved holes of the flange rings 4 one by one, improving the stability of the HVAC pipeline, ensuring the smooth flow of air, and saving time and effort at the same time. When it is necessary to regulate the air flow inside the pipeline, rotate the knob 17 to drive the main bevel gear 19 to rotate, and then drive the driven bevel gear 21 meshing with the main bevel gear 19 to rotate. The limit plate 18 can limit the main bevel gear 19 and the driven bevel gear 21. Then, the driven bevel gear 21 drives the straight rod 20 to rotate, so that the straight rod 20 can drive the baffle 24 to rotate inside the sliding sleeve 22, thereby regulating the gap between the baffle 24 and the sliding sleeve 22. The fixing frame 23 can limit the straight rod 20, and the sealing plug 25 can well seal the edges of the sliding sleeve 22 and the baffle 24, so as to achieve the effect of controlling the flow rate and flow volume of the gas inside the pipeline, improving the practicability of the HVAC pipeline, avoiding the waste of excess heating, and facilitating the replacement of the pipeline at the same time.
[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
