Description

Technical Field

[0001] The utility model relates to the technical field of rubber joints, in particular to a wear-resistant rubber joint. Background Art

[0002] Rubber joints are also called flexible rubber joints. Rubber flexible joints are composed of fabric-reinforced rubber parts and flat flexible joints, sleeve metal flanges or threaded pipe flanges. They are used for pipeline vibration isolation and noise reduction, and displacement compensation. They are pipe joints with high elasticity, high air tightness, medium resistance and weather resistance.

The above patent arranges a compressible compensation structure on the rubber joint, and when the rubber joint is used to connect the pipeline for noise reduction and vibration reduction, if the gap between the pipelines is too small and the installation is troublesome, the rubber tube can be compressed to a certain length by the compensation component, so as to facilitate the installation between two adjacent pipelines, thereby improving the convenience and efficiency of installation and use.

[0004] However, while solving the problem, the above patent cannot effectively prevent the friction caused by vibration. Although the patent has achieved certain shock absorption through the material of the rubber joint body, it will still have an impact on the compensation component during the vibration transmission process, which may cause wear or loosening of the compensation component, thereby affecting its long-term stability and service life.

[0026] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. The present invention is further described in detail below in conjunction with the accompanying drawings.

[0028] A wear-resistant rubber joint, such as Figure 1-Figure 5 As shown, it includes a rubber joint 1, a plurality of length compensation buffer components 2, a first flange 6 and a second flange 7. The first flange 6 and the second flange 7 are relatively installed on both sides of the opening of the rubber joint 1, and a plurality of length compensation buffer components 2 are movably installed between the first flange 6 and the second flange 7. A plurality of buffer springs 3 are fixedly arranged between the first flange 6 and the second flange 7. The plurality of length compensation buffer components 2 and the plurality of buffer springs 3 are arranged in a circular array with the axis of the first flange 6 as the center. The length compensation buffer components 2 and the buffer springs 3 are preferably three, and are arranged in a circular array at an angle of 120 degrees between the first flange 6 and the second flange 7 to ensure uniform distribution of force, enhance the overall stability and bearing capacity of the joint, and avoid local overload. The length of the rubber joint 1 body is adjusted by the length compensation buffer component 2, which can effectively adapt to the requirements of different lengths, bring good installation flexibility and adaptability, and cooperate with the buffer spring 3 for double shock absorption, which effectively reduces the friction between the rubber joint 1 and its connecting parts, reduces the wear rate, and extends the maintenance cycle and service life.

[0029] A mounting block 5 is provided on the side of the first flange 6 away from the opening of the rubber joint 1, and a convex block corresponding to the mounting block 5 is provided on the second flange 7, and a bearing 4 is installed in the convex block. The mounting block 5 and the convex block are arranged in a circular array with the axis of the first flange 6 as the center. The mounting block 5 is preferably three L-shaped metal blocks arranged in a 120-degree circular array, welded to a side of the first flange 6 away from the opening of the rubber joint 1, that is, a side close to the connecting end of the rubber joint 1. The three convex blocks of the second flange 7 are opposite to the three mounting blocks 5. A threaded hole is opened on the mounting block 5, and a bearing 4 hole is opened on the convex block. The bearing 4 hole and the threaded hole are on the same axis. The length compensation buffer assembly 2 includes a turning handle 21, a threaded roller 22 and a hydraulic buffer 23. The turning handle 21 is fixedly connected to the threaded roller 22. The threaded roller 22 is fixedly mounted on the telescopic end of the hydraulic buffer 23. The threaded roller 22 is threadedly connected to the mounting block 5. The turning handle 21 is mounted on one side of the mounting block 5 close to the opening of the rubber joint 1. The other end of the hydraulic buffer 23 is movably mounted on the convex block through the bearing 4. The first flange 6 is driven to adjust its length by rotating the turning handle 21. When the threaded roller 22 rotates, it will drive the fixedly mounted hydraulic buffer 23 to rotate. At this time, the rotational force is converted into a linear motion force with the help of the bearing 4, and the first flange 6 moves. A damper is installed on the buffer spring 3, and the dual shock absorption of the hydraulic buffer 23 and the buffer spring 3 effectively avoids the friction caused by vibration, so that the entire structure can work more stably when impacted, and the turning handle 21 abuts against the mounting block 5 of the first flange 6.

[0030] The rubber joint 1 includes an inner rubber layer 11, a skeleton layer 12, an outer rubber layer 13 and a corrosion-resistant layer 14. The skeleton layer 12 is coated on the outer surface of the inner rubber layer 11. The inner rubber layer 11 is located between the skeleton layer 12 and the corrosion-resistant layer 14. The outer rubber layer 13 is coated on the outer surface of the skeleton layer 12. The inner rubber layer 11 is made of nitrile rubber, the skeleton layer 12 is made of polyester cord, the outer rubber layer 13 is made of chloroprene rubber, and the corrosion-resistant layer 14 is made of polytetrafluoroethylene. Polytetrafluoroethylene has excellent corrosion resistance and can effectively resist the erosion of corrosive media to extend the service life of the rubber joint 1. Steel wire rings are installed inside the openings at both ends of the rubber joint 1. The outer sides of both ends of the rubber joint 1 are coated with wear-resistant high manganese steel sleeves 8. The nitrile rubber can enhance the resilience, compression permanent deformation, electrical properties, and tear resistance of the rubber joint 1. Strength, water swelling resistance and wear resistance, etc., can effectively seal the medium, protect the skeleton layer 12, and prevent water leakage and scouring. The polyester cord has good breaking strength, breaking stress and elastic modulus, which ensure the thermal expansion and expansion of the rubber joint 1 and the overall adhesion strength and pressure resistance. The chloroprene rubber protects the internal layer structure from the influence of the external environment and provides additional wear resistance. Because the outer rubber layer 13 is directly exposed to the air, it is easily affected by external factors. Steel wire rings are installed inside the openings at both ends of the rubber joint 1 to enhance the connection strength and sealing performance of the joint. The outer sides of both ends of the rubber joint 1 are coated with wear-resistant high manganese steel sleeves 8, and the inner sides of the two flanges are connected to the wear-resistant high manganese steel sleeves 8. The wear-resistant high manganese steel sleeves 8 increase the wear-resistant and pressure-resistant effects of the main body of the rubber joint 1.

[0031] Working principle: When in use, connect the first flange 6 and the second flange 7 to the pipe to be used. If the reserved gap between the two pipes is short during connection, the threaded roller 22 is driven to rotate by turning the handle 21, and the first flange 6 is driven to rise and fall in cooperation with the bearing 4, thereby completing the retraction and extension adjustment of the length of the rubber joint 1. The hydraulic buffer 23 cooperates with the buffer spring 3 and the multiple shock absorption of the damper, which not only increases the impact resistance but also effectively reduces the wear caused by vibration.

Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes for application in other fields.
