Description

Technical Field

[0001] This utility model relates to the technical field of universal hinge compensators, specifically an anti-disengagement universal hinge compensator. Background Technology

[0002] Universal hinge compensator is a flexible compensation device used in pipeline systems. Its core function is to absorb the displacement (including axial, lateral, and angular displacement) caused by thermal expansion and contraction, installation deviation, or foundation settlement of the pipeline, while reducing the additional stress of the pipeline on the equipment and protecting the safe operation of the pipeline and equipment. Most universal hinge compensators currently in use have difficulty preventing the fixed plate from disengaging. During use, if it is difficult to prevent the fixed plate from disengaging, the compensation angle of the bellows will be too large, causing the fixed plate to disengage, resulting in the compensator failure and leakage of the medium in the pipeline. If the medium in the pipeline is flammable, it can easily cause fires or explosions. If the medium in the pipeline is toxic, it can cause workers to be poisoned, making the universal hinge compensator less practical. Utility Model Content

[0003] The purpose of this invention is to provide an anti-disengagement universal hinge compensator to solve the problems raised in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an anti-disengagement universal hinge compensator, comprising a tube body, a flange and a fixing plate, wherein an anti-disengagement mechanism is provided on the outside of the fixing plate, the anti-disengagement mechanism comprising a mounting plate, wherein a mounting plate is provided on the outside of the fixing plate, and a first threaded hole is provided on the inside of the mounting plate and the inside of the flange, wherein a first bolt is provided on the inner wall of the first threaded hole.

[0005] As a preferred technical solution, the inner side of the flange is provided with limit rods, and the number of limit rods is two sets, with two in each set.

[0006] As a preferred technical solution, a groove is provided on the inner side of the flange, and the groove is rectangular in shape.

[0007] As a preferred technical solution, one end of the pipe body is provided with a corrugated pipe, and the outer wall of the pipe body is provided with a flange.

[0008] As a preferred technical solution, a fixing plate is provided inside the flange, and a third bolt is provided inside the fixing plate.

[0009] As a preferred technical solution, a vibration damping mounting mechanism is provided on the outer side of the flange, the vibration damping mounting mechanism including a rubber pad, and the outer side of the flange is provided with a rubber pad.

[0010] As a preferred technical solution, the number of rubber pads is four, and the interior of the rubber pads and the interior of the flange are both provided with second threaded holes.

[0011] As a preferred technical solution, the number of the second threaded holes is two sets, with four in each set, and the inner wall of the second threaded hole is provided with a second bolt.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the setting of an anti-disengagement mechanism, can prevent the universal hinge compensator from disengaging. During use, the mounting plate is firmly installed on the flange by the cooperation of the first bolt and the first threaded hole, so that the fixing plate is firmly installed on the compensator, preventing the fixing plate from loosening. Through the cooperation of the limit rod and the groove, the compensator can no longer compensate when it reaches the compensation limit. This can avoid the situation where it is difficult to prevent the fixing plate from disengaging, which would lead to an excessive compensation angle of the bellows, causing the fixing plate to disengage, the compensator to fail, and the medium in the pipeline to leak. If the medium in the pipeline is flammable, it may cause fire or explosion. If the medium in the pipeline is toxic, it may cause poisoning of workers. This ensures the practicality and safety of the universal hinge compensator.

[0013] 2. This utility model, through the setting of a vibration-damping installation mechanism, can achieve the goal of installing the pipeline with the compensator and reducing vibration during use. During use, the compensator is fixed to the pipeline by the cooperation of the second bolt and the second threaded hole. The rubber pad absorbs external vibration, reducing the impact of external vibration on the compensator. This avoids the situation where the process of installing the compensator with the pipeline is cumbersome and takes a long time, thus ensuring the ease of installation of the compensator. It also avoids the situation where the compensator is subjected to long-term vibration due to the difficulty in reducing vibration during use, which can cause metal fatigue of the bellows, micro-cracks, and ultimately leakage, thus ensuring the service life of the compensator.

[0016] 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.

[0017] Example: Figure 1 As shown, the present invention provides the following technical solution, including a pipe body 1, a flange 5 and a fixing plate 6. An anti-disengagement mechanism 2 is provided on the outside of the fixing plate 6. A corrugated pipe 4 is provided at one end of the pipe body 1. A flange 5 is provided on the outer wall of the pipe body 1. A fixing plate 6 is provided inside the flange 5. A third bolt 7 is provided inside the fixing plate 6. A vibration damping installation mechanism 3 is provided on the outside of the flange 5.

[0018] When the universal hinge compensator is needed, the fixing plate 6 must first be firmly installed on the flange 5. The anti-disengagement mechanism 2 is used to firmly install the fixing plate 6 on the flange 5. Then, the two fixing plates 6 in each group are fixed together with the third bolt 7. At this time, the pipe body 1 needs to be connected to the pipeline, and vibration damping treatment is applied to the connection. The vibration damping installation mechanism 3 is used to connect the pipe body 1 to the pipeline, and vibration damping treatment is applied to the connection. Then the compensator can be used for compensation work. The anti-disengagement mechanism 2 is used to prevent disengagement, thus completing the work.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, an anti-disengagement mechanism 2 is provided on the outside of the fixing plate 6. The anti-disengagement mechanism 2 includes a mounting plate 201. The mounting plate 201 is provided on the outside of the fixing plate 6. The mounting plate 201 and the flange 5 are both provided with first threaded holes 202. The inner wall of the first threaded hole 202 is provided with a first bolt 203. The flange 5 is provided with limit rods 204 on the inner side. There are two sets of limit rods 204, two in each set. The flange 5 is provided with a groove 205 on the inner side. The groove 205 is rectangular in shape.

[0020] When the universal hinge compensator is needed, the fixing plate 6 must first be securely installed on the flange 5. The fixing plate 6 is then passed through the flange 5, so that the mounting plate 201 is flush with the flange 5. The first threaded hole 202 in the mounting plate 201 is aligned with the first threaded hole 202 in the flange 5. Then, the first bolt 203 is rotated and inserted into the first threaded hole 202, securing the fixing plate 6 firmly onto the flange 5 to prevent disengagement. During the compensation process, the limiting rod 204 moves with the flange 5, entering the groove 205. When the compensator reaches its limit, the limiting rod 204 will press against the inner wall of the groove 205, preventing further compensation and disengagement, thus completing the anti-disengagement function.

[0021] like Figure 1 and Figure 4 As shown, a vibration damping mounting mechanism 3 is provided on the outer side of the flange 5. The vibration damping mounting mechanism 3 includes a rubber pad 301. There are four rubber pads 301 on the outer side of the flange 5. The inner side of the rubber pad 301 and the inner side of the flange 5 are provided with second threaded holes 302. There are two sets of two threaded holes 302, with four in each set. The inner wall of the second threaded holes 302 is provided with second bolts 303.

[0022] Specifically: When it is necessary to connect the pipe body 1 to the pipeline and perform vibration reduction treatment at the connection, the corresponding installation position on the pipeline is pressed tightly against the flange 5. Then, the second threaded hole 302 opened in the flange 5 is aligned with the second threaded hole 302 opened in the specific installation position on the pipeline. Then, the second bolt 303 is rotated and inserted into the second threaded hole 302 to install and fix the pipeline and the compensator together. Through the elasticity of the rubber pad 301 itself, some vibration can be absorbed, reducing the impact of vibration on the compensator, thereby completing the vibration reduction installation work.

[0023] The working principle of this utility model is as follows: When the universal hinge compensator is needed, firstly, the fixing plate 6 needs to be firmly installed on the flange 5. At this time, the fixing plate 6 is passed through the flange 5, so that the mounting plate 201 is close to the flange 5. At this time, the first threaded hole 202 in the mounting plate 201 is aligned with the first threaded hole 202 in the flange 5. Then, the first bolt 203 is rotated and inserted into the first threaded hole 202 to firmly install the fixing plate 6 on the flange 5 to prevent disengagement, thus completing the installation work. Then, the two fixing plates 6 in each group are fixed together by the third bolt 7. At this time, the pipe body 1 needs to be connected to the pipeline, and vibration damping treatment is applied to the connection. Then, the corresponding installation position on the pipeline is close to the flange 5, and then... The second threaded hole 302 inside the flange 5 is aligned with the second threaded hole 302 in a specific installation position on the pipeline. Then, the second bolt 303 is rotated and inserted into the second threaded hole 302 to fix the pipeline and the compensator together. Through the elasticity of the rubber pad 301, some vibration can be absorbed, reducing the impact of vibration on the compensator, thus completing the vibration reduction installation. Then, the compensator can be used for compensation. During the compensation process, the limit rod 204 will move with the movement of the flange 5, so that the limit rod 204 enters the groove 205. When the compensator compensates to the limit, the limit rod 204 will press against the inner wall of the groove 205, preventing it from continuing to compensate and preventing disengagement, thus completing the anti-disengagement work.
