Technical Field

[0001] The utility model relates to the technical field of pipe joints, in particular to a RES pipe joint. Background Technique

[0002] A corrugated pipe is a tubular component with a corrugated pipe wall. It is usually made of metal or plastic. Its corrugated shape increases the flexibility and extensibility of the pipe material, and it can generate displacement deformation in the axial, transverse, and angular directions, so as to absorb changes such as thermal expansion and contraction, vibration, and torsion of the pipeline, playing roles such as compensating displacement, reducing vibration and noise, and connecting different components.

However, in a harsh environment, the threaded connection method may be loosened gradually due to external vibrations, resulting in the failure of the sealing performance of the corrugated pipe joint connection, which is rather inconvenient.

DETAILED DESCRIPTION OF THE INVENTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] The present utility model provides a RES pipe joint as Figures 1-3 shown, which includes a joint body 1, and external threads are provided at both ends of the joint body 1;

[0029] Furthermore, a protection mechanism 2 is provided on one side of the joint body 1. The protection mechanism 2 includes: a metal support ring 21, a connecting pipe 22, a rubber sleeve 23, a locking member 24, and a fixing assembly 25. The metal support ring 21 is provided on one side of the joint body 1 and is used to support the inside of the bellows, thereby improving the bellows' ability to withstand internal pressure and external loads, preventing the bellows from deforming or collapsing excessively under high pressure, helping to maintain the shape and structural stability of the bellows, reducing vibration and displacement during the operation of the bellows, restricting excessive expansion and contraction of the bellows, ensuring its normal operation within the designed expansion and contraction range, extending its service life, the metal support ring 21 can also reduce the fatigue damage generated during the repeated expansion and contraction of the bellows, improving the durability of the bellows. When the bellows is subjected to a torsional force, the metal support ring 21 can reduce the degree of torsion and protect the structural integrity of the bellows; The connecting pipe 22 is fixedly connected to one side of the metal support ring 21. The connecting pipe 22 helps to balance the pressure between different regions inside the bellows, reducing the adverse effects caused by pressure differences on the bellows structure. If the fluid is transported inside the bellows, the connecting pipe 22 can make the fluid more evenly distributed, avoiding too high or too low local flow rates, thereby optimizing the performance of the system. It can be used to discharge gases or liquids that may accumulate in specific parts of the bellows, or as a detection port for facilitating sampling and monitoring of the internal medium. The connecting pipe 22 can increase the overall strength and rigidity of the metal support ring 21, further improving the support effect on the bellows; The rubber sleeve 23 is provided on one side of the connecting pipe 22 and is used to sleeved on the outside of the bellows. Rubber has good elasticity and sealing performance, which can effectively prevent the leakage of the medium from the connection of the bellows, improving the sealing reliability of the system. It can reduce the erosion and wear of the external environment on the bellows, such as chemical corrosion, mechanical collision, etc., extending the service life of the bellows. The rubber sleeve can absorb and buffer the vibration and noise generated during the operation of the bellows, reducing the vibration and noise level of the system. In some electrical or special environments, the rubber sleeve can provide good insulation, preventing current leakage or static electricity accumulation. The elasticity of the rubber can compensate for the dimensional deviation and installation error between the bellows and the metal support pipe 21 to a certain extent, making the connection tighter, helping to reduce the fatigue damage caused by the repeated deformation of the bellows, and enhancing its overall fatigue resistance. Rubber has a certain adaptability to thermal expansion and contraction and can maintain good adhesion during temperature changes, reducing sealing problems caused by temperature differences; The locking member 24 is provided on one side of the rubber sleeve 23 and is used to lock the rubber member to fix the bellows. The locking member 24 is a nut, and the nut is threadedly inserted into the joint body 1. The cross-section of the nut is hexagonal; The fixing assembly 25 is provided on the locking member 24 and is used for multi-point limiting of the locking member 24, thereby preventing the locking member 24 from accidentally rotating due to external factors, resulting in the failure of the sealing performance.

[0030] Specifically, the fixing component 25 includes: a sleeve 251, a pressing plate 252, a positioning rod 253, a compression spring 254, and a pull ring 255. A plurality of sleeves 251 are symmetrically and fixedly connected to the outer wall of the nut; the pressing plate 252 is located inside the sleeve 251; a plurality of positioning holes are equidistantly formed in the outer wall of the joint body 1. One end of the positioning rod 253 is slidably inserted into the inner cavity of the positioning hole, and the other end of the positioning rod 253 is fixedly inserted into the pressing plate 252; the compression spring 254 is sleeved outside the positioning rod 253. One end of the compression spring 254 is fixedly connected to the pressing plate 252, and the other end of the compression spring 254 is fixedly connected to the inner wall of the sleeve 251. The compression spring 254 is always in a compressed state, so as to provide a stable elastic force to the positioning rod 253 through the pressing plate 252, enabling the positioning rod 253 to extend out of the nut. After the nut is connected to the joint body 1, the positioning rod 253 is inserted into the positioning hole to position the locking member 24 and prevent it from rotating due to external factors, resulting in seal failure. The pull ring 255 is arranged on one side of the nut, and the other ends of the plurality of positioning rods 253 are fixedly connected to the pull ring 255. By pulling the pull ring 255, the plurality of positioning rods 253 can be displaced, so as to prevent the positioning rod 253 from extending out and affecting the normal installation of the nut when the nut is connected to the joint body 1. At the same time, after the limit, the positioning rod 253 can be pulled out of the insertion with the positioning hole, and the nut can be normally disassembled.

[0031] Furthermore, a sealing ring 3 is arranged outside the joint body 1 to block the flow of air in the gap between the external pipeline and the joint body 1, thereby ensuring the sealing performance of the two ends of the joint body 1.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
