Description

Technical Field

[0001] This utility model relates to the field of compensator technology, and in particular to a high-temperature resistant, sealed, multi-directional compensator. Background Technology

[0002] Corrugated compensators, also known as corrugated expansion joints or corrugated expansion joints, are products developed in my country this year that can replace imports. They are suitable for industries such as petroleum, chemical, mining and metallurgy, instrumentation, aerospace, shipbuilding, construction, power electronics, heating pipelines, and machinery manufacturing. They are used to compensate for asynchronous settlement of high-rise buildings and related equipment, to compensate for displacement of large oil tanks and pipeline supports caused by the earth's crust, and to compensate for deformation caused by thermal expansion and contraction of engineering pipeline systems.

[0003] Chinese patent document CN201220018763.5 discloses a corrugated compensator, including a corrugated compensator body and flanges installed at both ends of the corrugated compensator body. The corrugated compensator body has shaping rings on both its inner and outer sides. The outer shaping ring conforms to the troughs of the corrugated compensator body, and the inner shaping ring conforms to the crests of the corrugated compensator body. The corrugated compensator of this invention enhances the pressure resistance of the corrugated compensator body through the action of the shaping rings, resulting in a corrugated compensator with better pressure resistance and a longer service life.

[0004] However, the above patent has certain defects in use. Although the above design can meet the basic connection requirements, the sealing performance and strength of the compensator are often affected under high temperature conditions for a long time, and may even leak or be damaged, causing safety hazards.

[0005] To address these issues, a high-temperature resistant, sealed, multi-directional compensator is proposed. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, this utility model provides a high-temperature resistant, sealed, multi-directional compensator.

[0007] This utility model is achieved using the following technical solution:

[0008] A high-temperature resistant sealing multi-directional compensator includes a flange and a compensator body. The compensator body includes a bellows and a connecting pipe. There are three bellows. The connecting pipe is arranged between the bellows and welded to them. There are two flanges, which are symmetrically arranged. The flanges are fixedly connected to the bellows through the connecting pipe.

[0009] The compensator body has a flow guide tube inside, one end of which is welded and fixed to the inner wall of the compensator body. The right side of the compensator body has a heat dissipation ring inside, which is in close contact with the inner wall of the left connecting pipe. The heat dissipation ring has a cavity inside, which is filled with coolant.

[0010] The outer peripheral wall of the connecting pipe is provided with multiple sets of adjustment devices, and there are three sets of adjustment devices arranged along the circumference of the center of the connecting pipe.

[0011] The adjusting device includes multiple brackets, which are evenly and equidistantly fixed on the outer wall of the connecting pipe. Each bracket has a through hole, and a pull rod is installed inside the through hole. The pull rod passes through the bracket and has multiple external threads. Multiple nuts are installed on the pull rod and are located on both sides of the bracket.

[0012] The compensator body is equipped with a buffer device inside. The buffer device includes a buffer ring, an annular groove, a plurality of springs, and a slip ring installed in the annular groove and fixedly connected to the springs.

[0013] A sealing ring is provided on one side wall of the guide tube, and the sealing ring is bonded to the side wall of the guide tube.

[0014] The flange surface is provided with a raised ring, which is integrally connected to the flange.

[0015] The present invention has the following advantages over the prior art:

[0016] 1. By using bellows, connecting pipes and flanges in combination, multi-directional compensation capability is achieved in high-temperature environments, effectively alleviating the thermal stress caused by temperature changes in the pipeline. A heat dissipation ring is set inside the compensator, and a cavity is set inside the heat dissipation ring and filled with coolant. The design of the heat dissipation ring and coolant reduces the working temperature of the compensator, improves its high-temperature resistance, and thus ensures its sealing performance.

[0017] 2. By setting an adjustment device on the compensator, the distance between the nut and the support can be adjusted to allow the compensator to be adjusted in multiple directions according to the actual situation, adapting to different pipeline layouts and temperature changes.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figures 1 to 5 As shown, a high-temperature resistant sealing multi-directional compensator includes a flange 1 and a compensator body. The compensator body includes bellows 3 and connecting pipes 2. There are three bellows 3. The connecting pipes 2 are arranged between the bellows 3 and welded to them. The bellows 3 can absorb the thermal stress generated by the pipeline due to temperature changes. The connecting pipes 2 are responsible for connecting the bellows 3 to form an integral compensation structure. The bellows 3 are made of elastic material and have good flexibility and resilience. When the pipeline is subjected to thermal stress, the bellows 3 will deform, absorbing and dispersing the stress. The connecting pipes 2 ensure the stable connection between the bellows 3, so that the compensator can work as a whole.

[0027] Two flanges 1 are provided, symmetrically arranged, and are fixedly connected to the bellows 3 via connecting pipes 2; the flanges 1 are tightly fitted to the flange end face of the pipe or other equipment by bolts or other fasteners to form a sealed connection. The design of the convex ring 11 increases the contact area and friction, which helps to prevent fluid leakage.

[0028] The compensator body has a flow guide tube 7 inside, one end of which is welded and fixed to the inner wall of the compensator body. This flow guide tube 7 guides fluid flow and reduces the impact of the fluid on the compensator. Its design allows the fluid to flow along a specific path, avoiding direct impact on the internal structure of the compensator. Simultaneously, the flow guide tube 7 also supports and fixes the bellows 3. A heat dissipation ring 6 is located inside the right side of the compensator body. This ring is in close contact with the inner wall of the left connecting pipe 2. The heat dissipation ring 6 has a cavity 61 filled with coolant. The coolant absorbs heat, effectively reducing the operating temperature of the compensator.

[0029] Multiple sets of adjustment devices are provided on the outer peripheral wall of the connecting pipe 2. There are three sets of adjustment devices arranged along the circumference of the center of the connecting pipe 2.

[0030] The adjusting device includes multiple supports 5, which are evenly and equidistantly fixed to the outer wall of the connecting pipe 2. Each support 5 has a through hole, and a pull rod 4 is installed inside the through hole. The pull rod 4 passes through the support 5 and has multiple external threads. Multiple nuts 41 are also installed on the pull rod 4, located on both sides of the support 5. By adjusting the position of the nuts 41, the compensator can be adjusted in different directions to adapt to different pipeline layouts and temperature changes.

[0031] The compensator body is equipped with a buffer device 9, which includes a buffer ring 93. The buffer ring 93 has an annular groove containing multiple springs 92 and a slip ring 91. The slip ring 91 is installed within the annular groove and fixedly connected to the springs 92. When the pipeline is subjected to thermal stress, the guide cylinder 7 shifts, and the springs 92 and slip ring 91 absorb some of the stress, providing a buffering effect and protecting the compensator from damage.

[0032] A sealing ring 8 is provided on one side wall of the guide tube 7. The sealing ring 8 is adhered to the side wall of the guide tube 7 to ensure the sealing between the guide tube 7 and the compensator body.

[0033] The flange 1 has a raised ring 11 on its surface, which is integrated with the flange 1 to increase the sealing and stability of the connection between the flange 1 and the pipeline.

[0034] The working principle of this utility model is as follows: When in use, after the high temperature resistant sealing multi-directional compensator is installed, it is in the initial state. At this time, the bellows 3 is in a natural state without force, and the connecting pipe 2, the guide tube 7, the heat dissipation ring 6 and other components are in normal positions. The sealing ring 8 is tightly fitted between the guide tube 7 and the compensator body to ensure sealing.

[0035] When the pipeline system is heated, the temperature of the fluid inside the pipeline rises, causing thermal expansion of the pipeline and connecting parts. As the core component of the compensator, the bellows 3 begins to absorb the axial, angular and lateral displacements of the pipeline caused by thermal expansion. The deformation of the bellows 3 causes the connecting pipe 2 to also undergo corresponding displacement. However, the connecting pipe 2 is fixed between the bellows 3 by welding, ensuring the overall stability.

[0036] The guide tube 7 plays a guiding role during the deformation of the bellows 3, ensuring that the fluid flows smoothly inside the compensator and avoiding excessive impact on the compensator. As the pipeline temperature rises, the working temperature inside the compensator will also rise accordingly. At this time, the coolant in the heat dissipation ring 6 begins to absorb heat, absorbing and carrying away the heat generated by the compensator.

[0037] When the pipeline system needs to adjust the compensation amount, the position of the tie rod 4 on the support 5 can be changed by rotating the nut 41 in the adjustment device, thereby achieving fine adjustment of the compensator in different directions.

[0038] The spring 92 and slip ring 91 in the buffer device 9 play a buffering role during the deformation of the bellows 3, absorbing and dispersing stress, and protecting the compensator from damage.

[0039] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
