[0030] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1-7 , the present invention provides the following technical solutions.

[0032] Embodiment 1: In order to solve the problem in the prior art that the connecting ring is integrally designed, especially when a flange is provided on the outer side of the compensator, it is inconvenient to sleeved the connecting ring on the outer side of the pipeline. Therefore, through the following technical solutions in this embodiment, a spherical compensator convenient for maintenance is provided, which is provided with a first connecting pipe 1, a first ball head 2, a second ball head 3, a second connecting pipe 4, a mounting ring 5 and a connecting mechanism 6. The first connecting pipe 1 and the first ball head 2, and the second ball head 3 and the second connecting pipe 4 are all welded. The second ball head 3 is inserted into the first ball head 2. The connecting mechanism 6 includes connecting blocks 7 fixedly connected to the front and rear ends of the mounting ring 5, connecting grooves 8 opened in the middle of the connecting blocks 7, connecting columns 9 for connection, connecting rods 10 rotatably connected to the upper and lower ends of the connecting columns 9, and stoppers 11 for limiting. The connecting column 9 is clamped in the middle of the connecting groove 8, and a torsion spring is provided at the connection between the connecting column 9 and the connecting rod 10. The rotation angle range between the connecting column 9 and the connecting rod 10 is 0-90°, and the connecting rod 10 and the stopper 11 are fixedly connected. The stopper 11 and the connecting block 7 are in a fitting arrangement. As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, the mounting ring 5 is sleeved on the upper and lower ends of the second ball head 3, and then the stopper 11 is rotated to drive the connecting rod 10 to rotate with the connecting column 9. After rotating 90°, the torsion spring at the connection between the connecting rod 10 and the connecting column 9 undergoes elastic deformation. Then the connecting column 9 drives the connecting rod 10 and the stopper 11 to be inserted into the connecting groove 8. At the same time, the connecting column 9 is clamped in the connecting groove 8. After the stopper 11 passes through the connecting groove 8, the stopper 11 is directly released. At this time, the stopper 11 restores elastic deformation, so that the connecting rod 10 rotates with the connecting column 9. At this time, the stopper 11 and the connecting block 7 are in a fitting arrangement, showing a state as Figure 5 shown. Through the setting of the connecting mechanism 6, it is convenient to connect the mounting rings 5 at the upper and lower ends with each other, so that it is very convenient to form an integral body of the mounting rings 5 at the upper and lower ends and sleeve it on the outer side of the second ball head 3.

[0033] Embodiment 2: For the existing spherical compensating joint that is convenient for maintenance, the sealing effect at the joint is not good. Therefore, by providing the mounting ring 5 and the sealing ring 14, the mounting ring 5 is symmetrically sleeved on the upper and lower ends of the second ball head 3, and a sealing ring 14 is disposed in a fitting manner between the mounting ring 5 and the second ball head 3. As shown in Figure 4 and Figure 5 shown, move the mounting ring 5 so that the mounting ring 5 presses and positions the second ball head 3. At the same time, the mounting ring 5 is in a fitting arrangement with the first ball head 2, and the sealing ring 14 is disposed in a fitting manner between the mounting ring 5 and the second ball head 3, thereby being able to improve the sealing effect at the connection and prevent leakage.

[0034] Embodiment 3: For the existing spherical compensating joint that is convenient for maintenance, it is not convenient to disassemble, maintain, and inspect the joint. Therefore, by providing the mounting rod 12 and the mounting cap 13, the mounting rod 12 is respectively inserted at the edges of the mounting ring 5 and the first ball head 2, and mounting caps 13 for locking are threadedly connected to both the left and right ends of the mounting rod 12. The mounting caps 13 are respectively disposed in a fitting manner at the edges of the first ball head 2 and the mounting ring 5. As shown in Figure 1 and Figure 7 shown, insert the mounting rod 12 at the edges of the mounting ring 5 and the first ball head 2 respectively, and then rotate the mounting caps 13 threadedly connected to the outer surface of the mounting rod 12 so that the mounting caps 13 are in close contact with the first ball head 2 and the mounting ring 5 respectively, thereby facilitating the installation connection of the joint and eliminating the need to insert and remove bolts for connection, which is convenient for later maintenance and inspection of the joint.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
