Description

Technical Field

[0001] This utility model relates to the technical field of variable cross-section pipe devices, and in particular to a variable cross-section pipe device for dynamic hydraulic balance in a centralized heating system. Background Technology

[0002] Fixed piping systems may fail to adapt effectively to changes in flow rate in certain applications, leading to uneven water flow distribution and localized hydraulic imbalances. This imbalance typically occurs when pipes cannot flexibly adjust flow rates, especially under conditions of significant demand fluctuations. Fixed piping may be configured based on specific flow rate requirements during the design phase, but over time, actual flow rate changes often exceed expectations, resulting in excessively high or low flow rates in certain areas. This, in turn, affects the overall system efficiency. Such hydraulic imbalances can trigger a series of negative consequences, such as water pressure fluctuations, accelerated pipe aging, equipment damage, and even a decline in overall system operating efficiency. In complex piping networks, localized hydraulic imbalances can also cause some pipes to be overloaded while others remain underutilized, leading to energy waste and increased maintenance costs. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies. Fixed pipeline systems cannot effectively adapt to changes in flow rate in certain applications, leading to uneven water flow distribution within the system and resulting in local hydraulic imbalance. This hydraulic imbalance typically occurs when the pipeline cannot flexibly adjust the flow rate, especially when demand fluctuates significantly. Fixed pipelines may be configured according to specific flow rate requirements during design, but over time, actual flow rate changes often exceed expectations, resulting in excessive or insufficient water flow in local areas, which in turn affects the overall system efficiency. This hydraulic imbalance problem can trigger a series of negative impacts, such as water pressure fluctuations, accelerated pipeline aging, equipment damage, and even a decrease in overall system operating efficiency. In some complex pipeline networks, local hydraulic imbalance may also lead to overloading of some pipelines while other parts cannot be fully utilized, resulting in energy waste and increased maintenance costs. This invention provides a variable cross-section pipeline device for dynamic hydraulic balance in centralized heating systems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a variable cross-section pipe device for dynamic hydraulic balance of a centralized heating system, comprising a branch pipe, wherein an adjustment mechanism is provided inside the branch pipe, the adjustment mechanism comprising a flexible hose, the outer surface of the flexible hose being fixedly connected to the inner wall of the branch pipe near the port, four profile plates being provided on the outer surface of the flexible hose, two sliding grooves being formed on the outer surface of the profile plates, a sliding plate being slidably connected between the inner walls of two pairs of sliding grooves, a support plate being fixedly connected to one side of the sliding plate, a spring being provided on one side of the support plate, the other end of the spring being fixedly connected to the inner wall of the sliding groove, and the outer surfaces of the plurality of profile plates being fixedly connected to the outer surface of the flexible hose.

[0005] In a preferred embodiment, the outer surface of the spring is provided with a telescopic rod.

[0006] In a preferred embodiment, one end of the telescopic rod is fixedly connected to one side of the slide plate, and the other end of the telescopic rod is fixedly connected to the inner wall of the slide groove.

[0007] In a preferred embodiment, the outer surface of the branch pipe is fixedly connected to a support shell, and the inner wall of the support shell is slidably connected to the outer surface of the profile plate.

[0008] In a preferred embodiment, grooves are provided on both sides of the template, and sliding holes are provided on the inner wall of the grooves.

[0009] In a preferred embodiment, a slider is slidably connected to the inner wall of the sliding hole, and a limit plate is fixedly connected to one side of the slider.

[0010] In a preferred embodiment, the outer surface of the limiting plate is slidably connected to the inner wall of the groove.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] This invention uses a flexible hose fixed to the inner wall of a branch pipe. This allows four molded plates, four sliding plates, and four springs to work together to compress the hose, reducing the flow cross-section inside the branch pipe. As the internal pressure of the branch pipe and hose increases, the hose expands, pushing the four molded plates, four sliding plates, and four springs outwards, thus gradually increasing the flow cross-section. A telescopic rod protects the springs from bending and also supports and limits the sliding plates, stabilizing their movement. The support shell allows the four molded plates, four sliding plates, and four springs to slide into its interior. A slider further enhances the stability of the sliding plate's movement.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example

[0022] like Figure 1-4As shown, this utility model provides a technical solution: a variable cross-section pipe device for dynamic hydraulic balance of a centralized heating system, including a branch pipe 1. An adjustment mechanism 2 is provided inside the branch pipe 1. The adjustment mechanism 2 includes a flexible hose 21. The outer surface of the flexible hose 21 is fixedly connected to the inner wall of the branch pipe 1 near the port. Four profile plates 22 are provided on the outer surface of the flexible hose 21. Two sliding grooves 25 are opened on the outer surface of the profile plates 22. A sliding plate 23 is slidably connected between the inner walls of the two sliding grooves 25. A support plate 24 is fixedly connected to one side of the sliding plate 23. A spring 27 is provided on one side of the support plate 24. The other end of the spring 27 is fixedly connected to the inner wall of the sliding groove 25. The outer surfaces of the multiple profile plates 22 are fixedly connected to the outer surface of the flexible hose 21. A telescopic rod 26 is provided on the outer surface of the spring 27. One end of the telescopic rod 26 is fixedly connected to one side of the sliding plate 23. The other end of the telescopic rod 26 is fixedly connected to the inner wall of the sliding groove 25.

[0023] Through the above embodiments, by fixing the hose 21 to the inner wall of the branch pipe 1, the four profile plates 22, four slide plates 23 and four springs 27 can work together to squeeze the hose 21, thereby reducing the flow cross section inside the branch pipe 1. When the internal pressure of the branch pipe 1 and the hose 21 increases, the hose 21 can be pushed to expand, which in turn can push the four profile plates 22, four slide plates 23 and four springs 27 to spread outward, thereby gradually increasing the flow cross section. The telescopic rod 26 can protect the springs 27 to prevent them from bending. At the same time, the telescopic rod 26 can also support and limit the slide plates 23, making the movement trajectory of the slide plates 23 and the support plate 24 more stable.

[0024] The outer surface of the branch pipe 1 is fixedly connected to the support shell 3. The inner wall of the support shell 3 is slidably connected to the outer surface of the mold plate 22. The mold plate 22 has grooves 28 on both sides. The inner wall of the groove 28 has a sliding hole 29. The inner wall of the sliding hole 29 is slidably connected to the slider 210. The slider 210 is fixedly connected to one side of the limit plate 211. The outer surface of the limit plate 211 is slidably connected to the inner wall of the groove 28.

[0025] Through the above embodiments, the support shell 3 can cooperate with the four molded plates 22, the four sliding plates 23 and the four springs 27, so that the four molded plates 22, the four sliding plates 23 and the four springs 27 can slide into the interior of the support shell 3, and the slider 210 can further increase the movement stability of the sliding plate 23.

[0026] Working principle:

[0027] like Figure 1-4As shown, in use, by fixing the hose 21 to the inner wall of the branch pipe 1, the entire system can achieve specific functions through the cooperation of four profile plates 22, four slide plates 23, and four springs 27. When the hose 21 is connected to the branch pipe 1, the four profile plates 22, slide plates 23, and springs 27 work together to generate extrusion force, causing the diameter of the hose 21 to shrink, thereby reducing the flow cross section inside the branch pipe 1. This process effectively controls the flow rate and velocity, thus restricting the passage of fluid to a certain extent. However, when the pressure inside the system gradually increases, the pressure difference between the branch pipe 1 and the hose 21 also increases, causing the hose 21 to expand. The expansion of the hose will drive the four profile plates 22, four slide plates 23, and four springs 27 to expand outward. As these components expand outward, the flow cross section inside the branch pipe 1 also increases, thereby achieving the regulation of flow rate and velocity. This design allows the flow cross section to be dynamically adjusted according to changes in internal pressure to adapt to different flow requirements and ensure that the system can operate smoothly under different working conditions.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
