Description

Technical Field

[0001] This utility model relates to the field of balancing valve technology, specifically a pipeline network balancing valve. Background Technology

[0002] Pipeline balancing valves are key devices in fluid transport systems used to optimize media distribution, widely applied in heating, air conditioning, and industrial circulating water systems. Their core value lies in solving the problem of uneven flow distribution caused by differences in pipeline resistance, ensuring stable operation of each branch according to design parameters. In complex pipeline networks, significant differences exist in pipe length, diameter, number of bends, and resistance of terminal equipment in different branches, easily leading to excessive flow at the near end and insufficient flow at the far end. Balancing valves precisely regulate the resistance characteristics of each branch, dynamically matching design flow requirements, avoiding overheating, noise, or energy waste caused by localized overflow, while preventing insufficient heating or poor cooling in underflow areas. In practical applications, balancing valves require on-site calibration using professional commissioning tools (such as flow meters and differential pressure gauges), adjusting the opening segment by segment based on the total system flow and branch design values ​​to establish a scientific flow distribution system. The adjustment process must comprehensively consider factors such as pipeline topology, media temperature, and pressure fluctuations to ensure the system maintains dynamic balance under varying operating conditions. This device plays an irreplaceable role in improving system energy efficiency, extending equipment life, and ensuring end-user experience. It is a core component for achieving refined management in modern pipeline engineering.

[0003] The installation of pipeline balancing valves presents significant inconveniences when connecting them to the pipeline, directly impacting construction efficiency and system commissioning time. Traditional installation requires repeated calibration of the valve body's alignment with the pipeline axis, and flange or threaded connections are prone to bolt tightening difficulties due to space constraints. In some complex pipeline layouts, the size and weight of the balancing valve further increase the complexity of hoisting and positioning, especially in high-density pipeline areas where narrow operating space easily leads to installation deviations. Furthermore, the sealing at the connection points requires repeated adjustments; even slight errors can cause leakage risks, extending the subsequent commissioning period. Utility Model Content

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] Please see Figure 1-4A pipeline network balancing valve includes a valve body 1. Both ends of the valve body 1 are fixedly connected to a fixed flange 2. The outer side of the fixed flange 2 contacts a connecting flange 3. A sealing gasket 31 is slidably connected inside the connecting flange 3. The sealing gasket 31 is slidably connected to the fixed flange 2. The design of the sealing gasket 31 can increase the sealing performance between the fixed flange 2 and the connecting flange 3. A mounting seat 4 is fixedly connected to the outer side of the connecting flange 3. A connecting plate 41 is slidably connected inside the mounting seat 4. A connecting rod 42 is fixedly connected to the side of the connecting plate 41 near the valve body 1.

[0022] Please see Figure 2-4 The connecting rod 42 is slidably connected to the mounting base 4. The end of the connecting rod 42 away from the connecting plate 41 is fixedly connected to the fixing bracket 43. The fixing bracket 43 is slidably connected to the fixing flange 2. The mounting base 4 is rotatably connected to the threaded rod 44. The threaded rod 44 is threadedly connected to the connecting plate 41. The outer side of the threaded rod 44 is fixedly connected to the retaining ring 45. The retaining ring 45 contacts the inner wall of the mounting base 4. The retaining ring 45 can limit the threaded rod 44. The end of the threaded rod 44 away from the mounting base 4 is fixedly connected to the knob 46. The knob 46 contacts the mounting base 4. The mounting base 4 is provided with a limit mechanism 5.

[0023] Please see Figure 2-4 The limiting mechanism 5 includes a limiting frame 51. The limiting frame 51 is slidably connected to the outer side of the mounting base 4. A limiting block 52 is fixedly connected to the side of the limiting frame 51 near the knob 46. The limiting frame 51 contacts the knob 46, and the limiting block 52 is slidably connected to the knob 46. Through the design of the limiting frame 51 and the limiting block 52, the knob 46 can be limited. A fixing block 53 is fixedly connected to the outer side of the mounting base 4, and a fixing rod 54 is fixedly connected to the outer side of the fixing block 53. The fixing block 53 is slidably connected to the limiting frame 51, and the fixing rod 54 is slidably connected to the limiting frame. The sliding connection 51, through the design of the fixing block 53 and the fixing rod 54, can guide the limiting frame 51.

[0024] The specific implementation process of this utility model is as follows: In use, by installing the connecting flange 3 and the fixed flange 2, the limiting frame 51 is moved away from the knob 46, so that the limiting frame 51 slides on the fixed block 53, and the fixed rod 54 slides in the limiting ring 55, so that the fixed rod 54 squeezes the spring 56, and the limiting frame 51 drives the limiting block 52 to slide out of the knob 46, so that the limiting of the knob 46 can be released.

[0025] By rotating the knob 46, the knob 46 drives the threaded rod 44 to rotate, causing the threaded rod 44 to move with the connecting plate 41, thereby moving the connecting plate 41 on the threaded rod 44, causing the connecting plate 41 to drive the connecting rod 42 to move, and causing the connecting rod 42 to drive the fixed frame 43 to move, so that the fixed frame 43 slides and engages with the fixed flange 2, which can limit the connection of the connecting flange 3 and the fixed flange 2, thus keeping the connection between the connecting flange 3 and the fixed flange 2 stable.

[0026] Then, by releasing the limit bracket 51, the spring force of the spring 56 can drive the limit bracket 51 to move, causing the limit bracket 51 to drive the limit block 52 to move, so that the limit block 52 slides into the knob 46, thus limiting the knob 46 and keeping the connecting flange 3 stable after installation.
