Description

Technical Field

[0001] This utility model relates to the field of pipeline compensator technology, and more specifically, to a pipeline compensator with an adjustable support angle. Background Technology

[0002] A pipe compensator is a connecting component installed between pipes. Different pipe compensators can be installed depending on the substance being transported inside the pipe. By setting up the pipe compensator, thermal expansion and contraction can occur inside the pipe, thereby improving the stability of the pipe during use.

[0003] In actual use, after the flanges on both sides of the pipe compensator are bent and connected to the pipe, the pipe itself will bend to a certain extent. Due to the elasticity of the pipe itself, the stress of the pipe will be concentrated at the connection between the flanges on both sides and the pipe, which will cause gaps to appear in the connection between the pipe compensator and the pipe. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a pipe compensator with adjustable support angle to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An adjustable-angle pipe compensator includes a bellows, with flanges fixedly connected to both ends of the bellows. An angle support mechanism is provided on the outer side of the flanges. The angle support mechanism includes multiple connecting frames. The bottom end of each connecting frame is rotatably connected to the outer side of the bellows. A rotating seat is fixedly connected to one side of each connecting frame. The outer side of the rotating seat is rotatably connected to the inner side of the bellows. Two rotating seats are rotatably connected to the inner side of each connecting frame. A positioning ring is fixedly connected to one end of each rotating seat. A sliding groove is formed on the outer side of the positioning ring. An internal thread is rotatably connected to the outer side of the sliding groove. A rotating cylinder is fixedly connected to one side of the internal thread. A retaining ring is formed on the inner side of the rotating cylinder. Two push handles are fixedly connected to the outer side of the rotating cylinder. A connecting rod is slidably connected to the inner side of the rotating cylinder. Both ends of the connecting rod are formed with external threads. The outer side of the external threads is threaded to the inner side of the retaining ring. The outer side of the connecting rod is slidably connected to the inner side of the positioning ring. Two grooves are formed on one side of the flange. A gasket is fixedly connected to the inner side of each groove. A cavity is provided inside the gasket. A height adjustment mechanism is provided on the outer side of the flange.

[0007] By adopting the above technical solution, multiple rotating drums and retaining rings are used for thread transmission on the outer side of the corresponding external thread, so that the two flanges can be supported by multiple connecting rods. The stress of the bellows during bending is distributed and supported by multiple connecting rods, and the corresponding gaskets and the compression deformation of the cavity are used to maintain the connection and sealing between the pipe compensator and the external pipe.

[0008] As a further description of the above technical solution: the height adjustment mechanism includes multiple outer cylinders, one side of which is fixedly connected to one side of a flange, a guide groove is provided on one side of the outer cylinder, an internal thread is provided on the inner side of the outer cylinder, a support rod is slidably connected to the inner side of the outer cylinder, a push rod is fixedly connected to one side of the support rod, the outer side of the push rod is slidably connected to the inner side of the guide groove, multiple insertion holes are provided on the inner side of the support rod, pins are inserted into the inner side of the insertion holes, the outer side of the pins is inserted into the inner side of the outer cylinder, one end of the pins is provided with an external thread, the outer side of the external thread is threadedly connected to the inner side of the internal thread, and a pad is fixedly connected to the bottom of the support rod.

[0009] By adopting the above technical solution, the support rods extend from the bottom of the outer cylinder, allowing multiple support rods and pads at the bottom to provide support to the ground at different heights, thus enabling the pipe compensator to maintain effective support during long-term use.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. By setting up an angle support mechanism, compared with the existing technology, the deflection of the connecting frame and the rotating seat with the flange and the deflection of the connecting frame allow the bellows to be supported by four connecting rods after bending and deflecting at a certain angle. This disperses the stress generated by the bending of the bellows by the four connecting rods. Furthermore, the extrusion deformation of the gasket and the cavity ensures good sealing at the connection between the two flanges and the external pipeline, reducing stress damage to the bellows and extending its service life.

[0012] 2. By setting up a height adjustment mechanism, compared with the existing technology, multiple support rods and pads are used to support the pipe compensator at different rotation angles and the ground at different heights. This can support the weight of the pipe for a long time and prevent the pipe from sinking due to gravity or temperature changes. Attached Figure Description

[0020] 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.

[0021] The embodiments disclosed in this application are as follows: Figure 1-6The pipe compensator shown includes a bellows 1, with flanges 2 fixedly connected to both ends of the bellows 1. An angle support mechanism is provided on the outside of the flanges 2. The angle support mechanism includes multiple connecting frames 3. The bottom end of the connecting frame 3 is rotatably connected to the outside of the bellows 1. A rotating seat 13 is fixedly connected to one side of the connecting frame 3. The outside of the rotating seat 13 is rotatably connected to the inside of the bellows 1. Two rotating seats 2 rotatably connect to the inside of the connecting frame 3. A positioning ring 5 is fixedly connected to one end of the rotating seat 2 4. A groove 6 is opened on the outside of the positioning ring 5. An internal thread 1 8 is rotatably connected to the outside of the groove 6. A rotating cylinder 7 is fixedly connected to one side of the internal thread 1 8. A retaining ring 9 is opened on the inside of the rotating cylinder 7. Two push handles 10 are fixedly connected to the outside of the rotating cylinder 7. A connecting rod 11 is slidably connected to the inside of the rotating cylinder 7. Both ends of the connecting rod 11 are provided with... There is an external thread 12, the outer side of which is threaded to the inner side of the retaining ring 9. The outer side of the connecting rod 11 is slidably connected to the inner side of the positioning ring 5. Two grooves 14 are opened on one side of the flange 2. A washer 15 is fixedly connected to the inner side of the groove 14. A cavity 16 is provided inside the washer 15. A height adjustment mechanism is provided on the outer side of the flange 2. Rotating the rotating cylinder 7 corresponding to the side of the positioning ring 5 allows the retaining ring 9 inside the rotating cylinder 7 to perform threaded transmission on the external thread 12 on the outer side of the connecting rod 11. This causes multiple connecting brackets 3 on the outer side of the two flanges 2 to deflect on the outer side of the flanges 2. At the same time, by utilizing the deflection of the positioning ring 5 and the rotating seat 2 4 inside the connecting brackets 3, the multiple rotating cylinders 7 can adjust the position of the outer side of the external thread 12 on the outer side of the connecting rod 11. This allows the bending of the bellows 1 to be distributed and supported by multiple connecting rods 11.

[0022] Reference Figure 2 , Figure 4 and Figure 5 As shown, the height adjustment mechanism includes multiple outer cylinders 17. One side of the outer cylinder 17 is fixedly connected to one side of the flange 2. A guide groove 18 is provided on one side of the outer cylinder 17. An internal thread 19 is provided on the inner side of the outer cylinder 17. A support rod 20 is slidably connected to the inner side of the outer cylinder 17. A push rod 21 is fixedly connected to one side of the support rod 20. The outer side of the push rod 21 is slidably connected to the inner side of the guide groove 18. Multiple insertion holes 22 are provided on the inner side of the support rod 20. A pin 23 is inserted into the inner side of the insertion hole 22. The outer side of the pin 23 is inserted into the inner side of the outer cylinder 17. An external thread 24 is provided at one end of the pin 23. The outer side of the external thread 24 is threaded to the inner side of the internal thread 19. A pad 25 is fixedly connected to the bottom of the support rod 20. By sliding the support rod 20 on the inner side of the outer cylinder 17, the support rod 20 can drive the pad 25 to support the ground, so that the bottom of the pipe compensator can be effectively supported.

[0023] The working principle of this utility model is as follows: When connecting two pipes, first place the bellows 1 and two flanges 2 between the two pipes. According to the height of the two pipes, push rods 21 on one side of the two outer cylinders 17 at the bottom of the two flanges 2 that are in contact with the ground are pushed downwards, so that the push rods 21 can slide inside the guide groove 18. Then, the push rods 21 drive the support rods 20 to slide inside the outer cylinders 17. After that, the support rods 20 drive the gaskets 25 to contact the ground, so that the two gaskets 25 at the bottom of the two flanges 2 support the ground. Then, insert the corresponding pins 23 into the insertion holes 22 inside the outer cylinders 17 and the corresponding support rods 20, and rotate the pins 23 to drive the external thread 24 to thread the internal thread 19 on one side of the outer cylinder 17. This allows multiple support rods 20 and gaskets 25 to stably support the bellows 1 and flanges 2. Then, keep the flanges 2 on both sides of the bellows 1 at the same height as the connection between the two pipes. Finally, use a rotation method... The excess push handle 10 on the outside of flange 2 drives the rotating drum 7 and the retaining ring 9 to perform threaded transmission on the external thread 12 on the outside of the connecting rod 11. Under the transmission of multiple rotating drums 7 on one side of the two flanges 2, the two flanges 2 drive the bellows 1 to approach the connection of the two pipes. Then, by rotating the rotating drums 7 on both sides of the multiple connecting rods 11, the rotating drums 7 are limited by the internal thread 8 and the slide groove 6, and the rotating drums 7 perform threaded transmission on the corresponding external thread 12 through the retaining ring 9. At the same time, by using the rotation of the rotating seat 13 on the outside of the connecting frame 3 and the outside of the flange 2, the bellows 1 can be supported and limited by multiple connecting rods 11 after deflection, so that the bending stress of the bellows 1 is distributed and supported by multiple external threads 12. Finally, the connection between the two flanges 2 and the two pipes is bolted, so that the two gaskets 15 and the cavity 16 on one side of the two flanges 2 can squeeze the connection surface of the two pipes, so that the connection surface between the two flanges 2 and the pipes is sealed.
