[0016] 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. Example 1
[0017] Please see Figures 1-2 This utility model discloses a highly elastic expansion joint for complex working conditions, including a flange 1, a rubber expansion tube 2 installed on one side of the flange 1, and a protective component 3 installed on one side of the flange 1, wherein: The protective component 3 includes a mounting base 30, an mounting plate 31 is rotatably connected to the inner wall of the mounting base 30, a first rotating rod 32 is rotatably connected to one side of the inner wall of the mounting plate 31, and an adaptive adjustment connecting plate 33 for cooperating with the working tension of the rubber expansion tube 2 is installed on the outer surface of the first rotating rod 32. A compensation groove 34 is provided on one side of the connecting plate 33, and a middle plate 35 is slidably connected to the inner wall of the compensation groove 34 to adapt to the connecting plate 33.
[0018] Furthermore, second rotating rods 36 are installed on the inner walls of both ends of the middle plate 35. The second rotating rods 36 correspond to and cooperate with the compensation groove 34. A rubber protective sleeve 37 for protecting the rubber expansion tube 2 is installed on one side of the flange 1.
[0019] Furthermore, there are two flanges 1, and a rubber expansion tube 2 is provided in the middle of the two flanges 1. The two ends of the rubber expansion tube 2 are respectively fixedly connected to one side of one flange 1.
[0020] Furthermore, multiple mounting seats 30 are equidistantly installed on one side of each flange 1. The outer surface of the mounting seat 30 is fixedly connected to the inner wall of the flange 1. The inner wall of each mounting seat 30 is rotatably connected to a mounting plate 31 through a bearing.
[0021] When the pipeline expands or contracts due to factors such as temperature changes and pressure fluctuations, the rubber expansion tube 2 begins to work, undergoing tensile or compressive deformation. The protective component 3, which cooperates with the rubber expansion tube 2, then activates its adaptive adjustment. The mounting plate 31 rotates within the mounting base 30 to adapt to the initial deformation direction of the rubber expansion tube 2. Example 2
[0022] Based on the above embodiment 1, please refer to Figures 3-5 Each mounting plate 31 has a first rotating rod 32 rotatably connected to one side of its inner wall via a bearing. The outer surface of each first rotating rod 32 is fixedly connected to one side of the inner wall of a connecting plate 33. Each compensation groove 34 has a compensation groove 34 equidistantly provided on one side.
[0023] Furthermore, the compensation groove 34 is used to adjust the overall adjustment space of the working compensation protection component 3 in conjunction with the rubber expansion tube 2, and a middle plate 35 is provided between every two corresponding connecting plates 33.
[0024] Furthermore, both ends of each central plate 35 are rotatably connected to a second rotating rod 36 via bearings. The second rotating rod 36 is slidably connected to the inner wall of the compensation groove 34, and the inner wall of the rubber protective sleeve 37 is connected to the outer surface of the mounting plate 31.
[0025] The connecting plate 33 rotates under the action of the first rotating rod 32. At the same time, the middle plate 35 slides within the compensation groove 34 of the connecting plate 33, adaptively adjusting according to the deformation degree of the rubber expansion tube 2, providing additional compensation space for the rubber expansion tube 2, and ensuring that the expansion joint as a whole can work normally. The rubber protective sleeve 37 always wraps around the outside of the rubber expansion tube 2 and the protective component 3, playing a protective role and preventing external impurities, corrosive substances, etc. from damaging the rubber expansion tube 2 and the protective component 3.
[0026] The working principle and usage process of this utility model are as follows: two flanges 1 are fixed to the ends of the pipes that need to be connected and have complex working conditions, ensuring that both ends of the rubber expansion tube 2 are firmly connected to one side of the two flanges 1, thus completing the basic installation of the expansion joint.
[0027] Check whether each component of the protective assembly 3 is installed in place, including whether the mounting base 30 is firmly fixed to the inner wall of the flange 1, whether the mounting plate 31 is normally rotatably connected to the mounting base 30 through the bearing, whether the first rotating rod 32 is correctly connected to the mounting plate 31 and the connecting plate 33, whether the middle plate 35 is normally engaged with the compensation groove 34 on the connecting plate 33 through the second rotating rod 36, and whether the rubber protective sleeve 37 is well connected to the flange 1 and the mounting plate 31.
[0028] Operation process: When the pipeline expands or contracts due to factors such as temperature changes and pressure fluctuations, the rubber expansion tube 2 begins to work, undergoing tensile or compressive deformation. The protective component 3, which cooperates with the rubber expansion tube 2, then activates its adaptive adjustment. The mounting plate 31 rotates within the mounting base 30 to adapt to the initial deformation direction of the rubber expansion tube 2.
[0029] The connecting plate 33 rotates under the action of the first rotating rod 32. At the same time, the middle plate 35 slides in the compensation groove 34 of the connecting plate 33, and adaptively adjusts according to the degree of deformation of the rubber expansion tube 2, providing additional compensation space for the rubber expansion tube 2 and ensuring that the expansion joint as a whole can work normally.
[0030] The rubber protective sleeve 37 always wraps around the outside of the rubber expansion tube 2 and the protective component 3, playing a protective role and preventing external impurities, corrosive substances, etc. from damaging the rubber expansion tube 2 and the protective component 3.
