Description

Technical Field

[0001] This utility model belongs to the field of flange connectors, specifically relating to a flexible flange connection structure suitable for complex pipelines. Background Technology

[0002] Complex pipelines typically refer to pipeline systems with complex designs, layouts, or operating conditions. They usually involve a variety of materials, equipment, functions, and operating conditions, and are widely used in fields such as petrochemicals, pharmaceuticals, shipbuilding, power generation, and aerospace.

[0003] Flexible flange connections are an improved type of flange connection. Unlike traditional rigid flanges, they possess a degree of flexibility or elasticity, allowing them to adapt to minor offsets, vibrations, displacements, and stress changes in the piping system. Through structural design and material optimization, flexible flange connections achieve efficient, safe, and reliable pipeline connections under complex operating conditions.

[0004] Dynamic factors such as pressure fluctuations, vibrations, or offsets in complex piping systems can easily cause failures in traditional flange connections, while flexible flanges effectively absorb and buffer these factors through structural design, reducing the risk of accidents.

[0005] In practical applications, while traditional flexible flange structures achieve flexible connections for complex pipelines, they still have certain limitations. Specifically, traditional flexible flange connection structures are difficult to adjust freely in terms of height. Under complex working conditions, complex pipeline systems may experience height changes due to different requirements, and the pipeline height is usually determined by the fixed support frame, which cannot be adjusted by itself. This results in the need for external equipment or direct replacement of the support frame for height adjustment, making the process rather cumbersome.

[0006] Therefore, a flexible flange connection structure suitable for complex pipelines is proposed to solve the above problems. Utility Model Content

[0007] In view of one or more of the above-mentioned defects or improvement needs of the prior art, this utility model provides a flexible flange connection structure suitable for complex pipelines, which has the advantages of free height adjustment for different complex pipelines and flexible pipeline connection.

[0008] To achieve the above objectives, this utility model provides a flexible flange connection structure suitable for complex pipelines, including a height adjustment assembly and a flexible connecting flange; the flexible connecting flange is assembled on the height adjustment assembly;

[0009] The height adjustment component includes a base, and two support seats are provided on the upper surface of the base. Each of the two support seats vertically supports a mounting shaft; each of the two mounting shafts is provided with a guide rod.

[0010] Both of the optical rods are slidably provided with sliding seats on their exteriors, and both sliding seats are integrally provided with clamping seats on their exteriors. Both clamping seats are integrally provided with connecting plates on their opposite sides.

[0011] The flexible connecting flange includes two symmetrically arranged flanges, and a flexible connecting pipe is connected between the two flanges.

[0012] As a further improvement of this utility model, both of the sliding seats are integrally provided with bushings on their exteriors, and the bushings are internally threaded with adjusting bolts. One end of the adjusting bolt passes through the bushing and extends to abut against the side wall of the smooth rod.

[0013] As a further improvement of this utility model, the top ends of both optical rods are threaded with nuts.

[0014] As a further improvement of this utility model, two through holes are provided on both connecting plates.

[0015] As a further improvement of this utility model, four bolt shafts are arranged around the center of the two flanges, the four bolt shafts are rectangularly distributed and pass through the two connecting plates respectively; both ends of the four bolt shafts are threaded with nuts; and one end of each of the two flanges is connected to a connecting pipe.

[0016] In summary, the beneficial effects of the above-described technical solutions conceived by this utility model compared with the prior art include:

[0017] This utility model discloses a flexible flange connection structure suitable for complex pipelines. Through the connection of the connecting pipes on the sides of the two flanges to the complex pipeline, and the flexible connecting pipe between the two flanges, flexible connections to complex pipelines can be achieved. Simultaneously, through the mutual movement and cooperation of multiple structures within the height adjustment assembly, the flexible connecting flange can be freely adjusted in height.

[0022] 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.

[0023] Example

[0024] Depend on Figure 1-3 A flexible flange connection structure suitable for complex pipelines is provided, including a height adjustment assembly 1 and a flexible connecting flange 2; the flexible connecting flange 2 is assembled on the height adjustment assembly 1;

[0025] The height adjustment component 1 includes a base 11, with two support seats 12 on the upper surface of the base 11. Each of the two support seats 12 has a vertically mounted mounting shaft 13. Each of the two mounting shafts 13 has a guide rod 14.

[0026] Both light rods 14 are slidably provided with sliding seats 15 on their exteriors, and both sliding seats 15 are integrally provided with clamping seats 16 on their exteriors. Both clamping seats 16 are integrally provided with connecting plates 17 on their opposite sides.

[0027] The flexible connection flange 2 includes two symmetrically arranged flanges 21, and a flexible connection pipe 22 is connected between the two flanges 21.

[0028] In this embodiment, the complex pipeline can be flexibly connected by the connecting pipe 23 on the sides of the two flanges 21 and the flexible connecting pipe 22 between the two flanges 21. At the same time, the flexible connecting flange 2 can be freely adjusted in height by the mutual movement and cooperation of multiple structures in the height adjustment component 1. Compared with the traditional fixed height support, the flexible connecting flange 2 of this application can adapt to different complex pipeline heights or support point differences during installation, avoiding installation difficulties caused by infrastructure height deviations. At the same time, the height adjustment function enables the flexible connecting flange 2 to be applied to more complex environments such as uneven ground, inclined pipelines, and equipment connections at different heights, improving its versatility.

[0029] Specifically, refer to Figure 1-2 Both sliding seats 15 are integrally provided with bushings 18 on their exteriors. The bushings 18 are internally threaded with adjusting bolts 19. One end of the adjusting bolts 19 passes through the bushings 18 and extends to abut against the side wall of the smooth rod 14.

[0030] In this embodiment, the adjusting bolt 19 can be used to adjust the position of the sliding seat 15 on the light rod 14, thereby realizing the height adjustment of the two connecting plates 17.

[0031] Furthermore, during use, loosening the adjusting bolt 19 releases it from its restraint on the guide rod 14, allowing the sliding seat 15 to slide freely outside the guide rod 14. As the sliding seat 15 moves, the clamping seat 16 and connecting plate 17, integrally connected to it, move synchronously. After vertical height adjustment, the user tightens the adjusting bolt 19 again into the bushing 18 until the end of the adjusting bolt 19 abuts against the side wall of the guide rod 14, thus maintaining the position of the connecting plate 17.

[0032] Specifically, refer to Figure 1-2 Both of the two bare rods 14 have nuts threaded to their top ends.

[0033] In this embodiment, the nut on the top of the light rod 14 can be used to prevent the sliding seat 15 from slipping during sliding, thereby limiting the sliding height of the sliding seat 15.

[0034] Specifically, refer to Figure 1-2 Two through holes are provided on each of the two connecting plates 17.

[0035] In this embodiment, the through holes provided on the connecting plate 17 can be used for the bolt shafts 24 to pass through. When the user inserts the four bolt shafts 24 into the through holes in the connecting plate 17 in sequence, the bolt shafts 24 can then follow the connecting plate 17 to achieve free height adjustment.

[0036] Specifically, refer to Figure 3 Four bolt shafts 24 are arranged around the center of the two flanges 21. The four bolt shafts 24 are rectangularly distributed and pass through the two connecting plates 17 respectively. Nuts are threaded to both ends of the four bolt shafts 24. A connecting pipe 23 is provided at one end of each of the two flanges 21.

[0037] In this embodiment, the user can pass the bolt shaft 24 through the connecting plate 17 and use a suitable bolt to position and install the bolt shaft 24 on the connecting plate 17. At this time, through the connection between the connecting plate 17 and the bolt shaft 24, the bolt shaft 24 can follow the connecting plate 17 to complete the height adjustment movement. At the same time, through the connection between the bolt shaft 24 and the two flanges 21, the flanges 21 can also be adjusted in height synchronously.

[0038] This utility model provides a flexible flange connection structure suitable for complex pipelines:

[0039] Step 1: In actual use, when the user needs to make flange connections for complex pipelines, first pass the four bolt shafts 24 in the flexible connection flange 2 through the through holes in the two connecting plates 17 in sequence, and at the same time, symmetrically fit the two flanges 21 on the four bolt shafts 24. Then, the user uses the appropriate nuts to position and install the two flanges 21 on the outside of the bolt shafts 24.

[0040] Step 2: After the two flanges 21 and the bolt shaft 24 are installed in a limiting position, the user can connect the two ends of the complex pipeline to one of the connecting pipes 23 respectively. The complex pipeline is connected through the connecting pipes 23 on the sides of the two flanges 21 and the flexible connecting pipe 22 between the two flanges 21.

[0041] Step 3: When the installation requirements of complex pipelines change, the user can loosen the adjusting bolt 19 to release it from the limit on the smooth rod 14. At this time, the sliding seat 15 can slide freely outside the smooth rod 14. After the vertical height adjustment is completed, the user tightens the adjusting bolt 19 into the bushing 18 until the end of the adjusting bolt 19 is tightly against the side wall of the smooth rod 14. At this time, the position of the connecting plate 17 can be maintained. Through the insertion between the connecting plate 17 and the smooth rod 14, when the height of the connecting plate 17 is adjusted, the two connecting plates 17 can drive the two flanges 21 to adjust the overall height.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
