Description

Technical Field

[0001] This utility model relates to the field of pipeline compensation equipment, and in particular to a high-pressure resistant self-balancing expansion joint stabilization mechanism. Background Technology

[0002] In industrial pipeline systems, due to factors such as temperature changes and medium flow, pipelines often experience thermal expansion and contraction, which can lead to axial, lateral, or angular displacements. To compensate for these displacements and ensure the safe and stable operation of the pipeline system, expansion joints are usually installed in the pipeline.

[0003] However, under some high-pressure conditions, the high-pressure medium can exert a large thrust on the expansion joint, which can easily cause the expansion joint to deform or even be damaged, affecting its service life and compensation effect. At the same time, the expansion joint has poor stability during the compensation displacement process, and may experience shaking, displacement, etc., which can adversely affect the stability of the entire pipeline system and even cause safety accidents. To address these issues, we propose a high-pressure resistant self-balancing expansion joint stabilization mechanism. Utility Model Content

[0021] 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.

[0022] Please see Figure 1-5 In this utility model, the high-pressure resistant self-balancing expansion joint stabilizing mechanism includes two pipes 1. The outer surfaces of the two pipes 1 are connected to first fixing plates 3. The two pipes 1 are provided with an expansion joint body 2 on their adjacent sides. The outer surfaces of the expansion joint body 2 are connected to two second fixing plates 4. The adjacent sides of the two first fixing plates 3 are connected to multiple telescopic rods 10. The outer surfaces of the two pipes 1 are provided with slots 5. The outer surfaces of the expansion joint body 2 are connected to two locking blocks 6. The two locking blocks 6 are adapted to the slots 5.

[0023] A connecting assembly 8 is provided on the outer surfaces of the two first fixing plates 3 and the second fixing plate 4. The connecting assembly 8 includes multiple threaded holes 801. Each set of threaded holes 801 is provided on the outer surface of the first fixing plate 3 and the second fixing plate 4. A fastening bolt 802 is threadedly connected to the inner wall of each set of threaded holes 801. By rotating the fastening bolt 802, the fastening bolt 802 rotates within the inner wall of the threaded hole 801, thereby effectively connecting the first fixing plate 3 and the second fixing plate 4, increasing the firmness of the connection between the expansion joint body 2 and the pipe 1. The outer surface of each first fixing plate 3... Each surface is connected to a mounting assembly 9. Each mounting assembly 9 includes two support rods 901. The bottom surface of each support rod 901 is connected to a mounting plate 902. The outer surface of each mounting plate 902 has two mounting holes 903. The inner wall of the mounting hole 903 is provided with a wear-resistant bushing made of brass. Through the cooperation of the support rods 901, mounting plates 902 and mounting holes 903, the device can be effectively and securely installed in the required position. At the same time, the brass wear-resistant bushing in the mounting hole 903 can reduce the wear on the hole wall during installation and extend the service life.

[0024] A metal sealing ring is provided at the connection between the expansion joint body 2 and the pipeline 1. The inner side of the metal sealing ring is tightly fitted to the outer wall of both the expansion joint body 2 and the pipeline 1. The metal sealing ring at the connection between the expansion joint body 2 and the pipeline 1 effectively enhances the sealing performance of the connection, prevents leakage of high-pressure media, and ensures the safe operation of the pipeline 1. Rubber gaskets 7 are connected inside both slots 5. Both rubber gaskets 7 are made of fluororubber. Fluororubber rubber gaskets 7 have good corrosion resistance and wear resistance, which can reduce wear between the locking block 6 and the slot 5, and also enhance the sealing performance at the joint. The expansion joint body 2 is made of high-pressure resistant alloy material. The expansion joint body 2 has a multi-layer reinforcing rib structure inside. By using high-pressure resistant alloy material and having a multi-layer reinforcing rib structure inside the expansion joint body 2, the high-pressure resistance and structural strength of the expansion joint body 2 are significantly improved, enabling it to adapt to high-pressure working conditions.

[0025] The working principle of this utility model is as follows:

[0026] In use, firstly, align the locking blocks 6 at both ends of the expansion joint body 2 with the locking grooves 5 on the outer surfaces of the two pipes 1, and insert the locking blocks 6 into the locking grooves 5 so that the locking blocks 6 and the rubber pads 7 in the locking grooves 5 are in close contact. Then, thread the fastening bolts 802 into the corresponding threaded holes 801 on the first fixing plate 3 and the second fixing plate 4. By tightening the fastening bolts 802, the first fixing plate 3 and the second fixing plate 4 are firmly connected together, thereby stabilizing and fixing the expansion joint body 2. Then, during the operation of the mechanism, when the pipe 1 is displaced due to temperature changes, the expansion joint body 2 will undergo corresponding compensation deformation. At this time, the telescopic rod 10 will extend and retract with the change in distance between the first fixing plate 3 and the second fixing plate 4. At the same time, its length can be locked by the locking bolts of the telescopic rod 10, which provides support and limit for the first fixing plate 3 and the second fixing plate 4, ensuring the stability of the expansion joint body 2 during the displacement compensation process.
