[0002] The spherical rotary joint for PE pipes is a special rotary connection device used to connect PE pipes, which can meet the rotational requirements existing in the pipeline system. Good sealing performance: Ensure that the medium will not leak during rotation. Since the PE material itself has good corrosion resistance, this rotary joint can also work stably in a corrosive environment. Compared with traditional pipeline joints, the spherical rotary joint for PE pipes can better adapt to complex working conditions and movement requirements, providing guarantee for the efficient and stable operation of the PE pipeline system.

[0003] For example, a spherical rotary joint for PE pipes disclosed in the utility model with the authorization announcement number of CN220816945U makes the external part of the rotary joint be flexibly closed and protected through the combination of various structures, avoiding the situation that dust outside enters the inside during the use of the rotary joint and reduces the smoothness during adjustment. At the same time, it also avoids the situation that the sealing performance of the rotary joint decreases due to dust, increasing the stability during the use of the rotary joint. And this rotary joint can be reinforced during the installation and connection with the PE pipe, avoiding or reducing the situation that the PE pipe falls off due to vibration or external tensile force when installed on the rotary joint, increasing the stability during the use of the rotary joint.

[0004] However, the following problems still exist when this existing technology is in use:

[0005] When an accordion tube is sleeved outside the rotary joint for protection and dust isolation, it is easy to affect the rotational flexibility, and the sealing performance and stability of the rotary joint need to be improved. Therefore, we propose a spherical rotary joint for PE pipes to solve the problems mentioned above. Content of the Utility Model

[0022] Embodiment

[0023] Please refer to Figures 1-4 As shown, the present utility model provides a spherical rotary joint for PE pipes,

[0024] An annular groove 2 is opened at the inner end of the mounting seat 1, a connecting block 3 is slidably installed at the inner end of the annular groove 2, a spherical joint 4 is fixedly installed at the inner end of the connecting block 3, a connecting pipe 5 is integrally installed at the outer end of the spherical joint 4, an inner joint 6 is slidably installed at the inner end of the spherical joint 4, a threaded groove 8 is opened at the inner end of the mounting seat 1, a mounting ring 9 is threadedly connected to the inner end of the threaded groove 8, an anti-pollution ring 10 is fixedly installed at the outer end of the mounting ring 9, and a ball 11 is rotatably installed at the inner end of the anti-pollution ring 10, making the structure more stable and durable during rotation and having good sealing performance.

[0025] The anti-pollution ring 10 is arranged outside the connecting pipe 5, and the ball 11 is attached to the outer wall of the connecting pipe 5. The inner joint 6 is integrally installed with the mounting seat 1, and a sealing ring 7 is arranged outside the inner joint 6. The sealing ring 7 is installed at the outer end of the spherical joint 4, and the spherical joint 4 is slidably installed inside the mounting seat 1. A connecting plate 12 is fixedly installed at the outer end of the mounting seat 1, and a mounting hole 13 is opened at the inner end of the connecting plate 12. The balls 11 are installed at equal angles inside the anti-pollution ring 10. When the connecting pipe 5 rotates, it drives the balls 11 to rotate inside the anti-pollution ring 10, preventing dust at the docking part while not affecting the smoothness of rotation and being easy to install.

[0026] Specific working principle:

[0027] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, when using this spherical rotary joint of PE pipe, connect the connecting pipe 5 with the rotating interface, connect the connecting disc 12 with the conveying structure to be connected through the mounting holes 13. When the connecting pipe 5 rotates, it drives the spherical joint 4 to rotate between the mounting seat 1 and the inner joint 6, and at the same time drives the connecting block 3 to rotate inside the annular groove 2, making the structure of the spherical joint 4 more stable and not prone to shaking and leakage during long-term use. The sealing ring 7 improves the sealing performance of the structure at the same time. The anti-pollution ring 10 is installed at the interface between the connecting pipe 5 and the mounting seat 1. The anti-pollution ring 10 can intercept external impurities from entering between the mounting seat 1, the connecting pipe 5 and the spherical joint 4 and affecting the smoothness. When the connecting pipe 5 rotates, it drives the ball 11 to rotate inside the anti-pollution ring 10 without affecting the smooth rotation of the connecting pipe 5. When it is necessary to disassemble the anti-pollution ring 10, thread the anti-pollution ring 10 outward so that the mounting ring 9 rotates out from the inside of the thread groove 8, and then the anti-pollution ring 10 can be disassembled. The above completes a series of operations of this spherical rotary joint of PE pipe. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
