Description

Technical Field

[0001] The utility model relates to the technical field of corrugated compensators, in particular to an axial corrugated compensator. Background Technique

[0002] A corrugated compensator is a compensation element, also known as an expansion joint or a telescopic joint. It utilizes the effective telescopic deformation of the working main bellows to absorb the dimensional changes of pipelines, conduits, containers, etc. caused by thermal expansion and contraction, etc., or compensates for the axial, lateral, and angular displacements of pipelines, conduits, containers, etc. This kind of compensator is mainly used for noise reduction and vibration damping and is widely used in modern industry.

[0003] A corrugated compensator mainly consists of accessories such as bellows, end pipes, brackets, flanges, conduits, etc. Among them, the bellows is the core part of the compensator. It is an elastic element that absorbs the dimensional changes of the pipeline through its telescopic deformation. The working principle of the compensator is to utilize the telescopic deformation of the bellows to compensate for the displacement of the pipeline. Secondly, in order to ensure the stable operation of the compensator, multiple tie rods are arranged on the surface of the corrugated compensator. The tie rods can be used to adjust the working state of the compensator, including the displacement amount, stiffness, and elastic characteristics of the compensator, etc. By adjusting the position of the nut on the tie rod, the normal operation of the compensator can be ensured, preventing it from being subjected to excessive stress and displacement, and avoiding the fracture of the corrugation due to excessive displacement.

[0004] However, on most existing compensators, the nut is threadedly sleeved on the tie rod. When the staff needs to adjust the position of the nut, it makes the staff need to use tools to adjust the position of the nut, which is too troublesome and easily affects the work efficiency of the staff. Therefore, the present utility model is proposed to solve the above problems. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the present utility model provides an axial corrugated compensator, which has the advantages of being convenient for adjusting the position of the nut on the tie rod, etc., and solves the problem that when the staff needs to adjust the position of the nut, it makes the staff need to use tools to adjust the position of the nut, which is too troublesome and easily affects the work efficiency of the staff.

[0006] To achieve the above object, the present utility model provides the following technical solution: An axial corrugated compensator, comprising a bellows, fixed disks are fixedly installed at both ends of the bellows, a plurality of mounting holes are formed on the surfaces of the two fixed disks, and an adjusting assembly is arranged between the two fixed disks.

[0007] The adjusting assembly includes a connecting member arranged between the two fixed disks, and a plurality of moving members and pushing members are arranged on one side of the connecting member facing the two fixed disks;

[0008] The connecting piece includes threaded rods arranged on both sides of the corrugated pipe. Both ends of the two threaded rods vertically penetrate through the fixed disk in a threaded manner, and relatively-shaped moving disks are slidably sleeved on the surfaces of both threaded rods.

[0009] Furthermore, the moving part includes a first sleeve fixedly installed on the surface of the fixed disk facing the moving disk. The other end of the first sleeve is fixedly connected to one side surface of the moving disk. An airbag is arranged inside the first sleeve. One end of the airbag is connected to an air delivery pipe. The inner wall of the air delivery pipe is provided with internal threads. The other end of the air delivery pipe extends to the outside of the fixed disk and is provided with a plugging piece.

[0010] Furthermore, the plugging piece includes a threaded block threadedly installed on the inner wall of the air delivery pipe. A fixed block is fixedly installed at the end of the threaded block away from the air delivery pipe. A grasping groove is formed on one side surface of the fixed block away from the threaded block.

[0011] Furthermore, the pushing-back part includes a second sleeve fixedly installed on the surface of the fixed disk facing the moving disk. The other end of the second sleeve is fixedly connected to one side surface of the moving disk. Permanent magnets are fixedly installed on both the inner bottom wall and the inner top wall of the second sleeve.

[0012] Furthermore, nuts are threadedly sleeved on the ends of the two threaded rods away from the two fixed disks. One ends of the four nuts are in contact with one side surfaces of the corresponding fixed disks.

[0013] Compared with the prior art, the present utility model provides an axial corrugated compensator, which has the following

[0014] beneficial effects:

[0015] In this axial corrugated compensator, the moving disk is used to replace the nut to support the fixed disk, so that when the moving disk can support the moving disk, the surface of the fixed disk can be evenly stressed. By setting the adjusting component, when the staff needs to adjust the position of the moving disk, they only need to deliver gas into the air delivery pipe to adjust the position of the moving disk, which saves time and effort, reduces the workload of the staff, improves work efficiency, and improves the practicability of the present utility model.

[0022] It should be noted that a fixed cylinder is arranged on the inner wall of the bellows 1, also known as a fixed ring or fixed bracket, which is a device for supporting and fixing the bellows 1, used to increase the stability of the bellows 1 and prevent it from undergoing excessive deformation or displacement during operation. The fixed cylinder can be fixed to the inner wall of the bellows 1 by welding, bolt connection or other means.

[0023] Please refer to Figure 1 and, Figure 2 and Figure 3 , in this embodiment, the adjusting component includes a connecting piece arranged between the two fixed disks 2.
