Description

Technical Field

[0001] The utility model relates to the technical field of expansion joints, in particular to a multi-angle reversing type tubular expansion joint. Background Art

[0002] An expansion joint, also known as a compensator or expansion joint, is a flexible structural component installed on a pipeline system or the outer shell of a container. It is mainly used to absorb and compensate for the thermal expansion or contraction of the pipeline or container caused by temperature changes or mechanical vibrations, as well as the resulting stresses. The expansion joint absorbs these displacements through its own elastic deformation, thereby protecting the entire system from damage. The expansion joint is a very important component and plays an indispensable role in many industrial pipeline systems, which is crucial for ensuring the safe operation of the system.

[0003] The Chinese invention patent with the application number CN209084268U discloses an expansion joint. The patent includes: an expansion joint body; a temperature-adjusting heat exchange tube, which is arranged in the heat insulation layer of the expansion joint body and is used to adjust the temperature near the expansion joint body. In the expansion joint provided by the utility model, a temperature-adjusting heat exchange tube is arranged in the heat insulation layer of the expansion joint body. By adjusting the flow rate and temperature of the heat exchange medium in the temperature-adjusting heat exchange tube, the temperature near the expansion joint body can be adjusted, avoiding the problem of overheating of the expansion joint that is likely to cause damage to the expansion joint, and also avoiding the problem of steam condensation caused by the overcooling of the expansion joint, which is likely to cause the failure of the heat insulation layer. It reduces the incidence of accidents at the expansion joint under special working conditions, and at the same time expands the elastic space for the use of the expansion joint, further improving the service life of the expansion joint and the stability of the process.

[0004] In the prior art, in order to avoid the fracture problem caused by various deformations when pipelines are connected to each other, a flexible tube is generally installed at the pipeline connection. The flexible tube can ensure buffering when the pipeline deforms axially. However, since the flexible tube can only expand and contract in the axial direction, once the pipeline is misaligned and deformed at other angles, this flexible tube loses its adjustment effect. Therefore, there are certain deficiencies in the adjustment effect of the expansion joints in the prior art. Summary of the Utility Model

[0028] Front docking assembly 2, the front docking assembly 2 includes a first flange 17 fixedly installed on one side of the input pipe 1, and the first flange 17 is used for docking and installing the input pipe 1. A buckle plate 15 is snap-fitted on one side of the first flange 17, and the function of the buckle plate 15 is to dock and install the flexible pipe 5. A hole 16 is opened in the middle of the buckle plate 15, and the hole 16 is in communication with the input pipe 1.

[0032] Rear docking assembly 4, the rear docking assembly 4 includes a second flange 20 snap-fitted on one side of the docking seat 12, and the function of the second flange 20 is to dock and install the output pipe 22; an output pipe 22 is inserted and installed in the middle part of the second flange 20.

[0034] A multi-angle reversing type tubular expansion joint, the front docking assembly 2, the multi-angle flexible assembly 3 and the rear docking assembly 4 are all arranged in a coaxial straight line, ensuring the stability of the device during fluid transmission.

[0035] In the actual creation process of the present utility model, in order to avoid the following defects existing in the prior art: "In the prior art, in order to avoid the fracture problems caused by various deformations during the docking of pipelines, flexible pipes are generally installed at the pipeline joints. The flexible pipe can ensure buffering when the pipeline deforms axially. However, since the flexible pipe can only expand and contract in the axial direction, once the pipeline is misaligned and deformed at other angles, this flexible pipe loses the adjustment effect. Therefore, there are certain deficiencies in the adjustment effect of the expansion joint in the prior art." The multi-angle flexible assembly 3, the front docking assembly 2 and the rear docking assembly 4 are specifically proposed.

[0036] When in use, the input pipe 1 and the output pipe 22 of the pipeline can be respectively installed on the main body of the device through the front docking component 2 and the rear docking component 4. The front docking component 2 mainly fixes the input pipe 1 on the surface of the first flange 17 by fixing the input pipe 1, and then fixes the first flange 17 on one side of the buckle plate 15 through the first bolt 18 and the nut 19 around it. Similarly, the output pipe 22 is fixed on one side of the docking seat 12 through the second flange 20 and the second bolt 21.

[0037] The actually functioning part of this device is the multi-angle flexible component 3. The flexible pipe 5 arranged near the input end has a certain telescopic effect and can play a buffering role axially. In order to buffer the possible bending problems at the pipeline connection, we set a ball support 7 inside the base 6. The ball hinge 8 can rotate freely inside the ball support 7 and is connected to the bottom of the docking seat 12 through a rod 9. No matter how the pipe fittings on both sides twist, the ball hinge 8 can achieve the effect of angle buffering by rotating relative to the docking seat 12 through the rod 9. However, in order not to affect the gas transmission, we set air holes 13 at the bottom of the docking seat 12 and transmit the gas or fluid at the input end through the insertion of the hose 11. Since the rotating part will undergo angle transformation, the flexible structure of the hose 11 can adapt to this rotation and avoid the problem of its own fracture.
