Description

Technical Field

[0001] The utility model relates to the technical field of non-metal expansion joints, in particular to a multi-directional buffer structure for non-metal expansion joints. Background Art

[0002] Non-metal expansion joints are connectors used in piping systems or equipment, usually used to compensate for changes in the length of pipes or equipment caused by temperature changes or mechanical vibrations. They are usually made of flexible materials such as rubber, polymers or metal bellows, and have good elasticity and deformation capabilities. The multi-directional buffer structure of non-metal expansion joints can provide buffering and compensation in multiple directions, and has good adaptability to changes in the length of pipes or equipment, which can effectively reduce stress concentration in the system and fatigue damage to pipes or equipment. Through the elastic properties of the expansion joint's own material, it can deform accordingly when the length of the pipe or equipment changes, thereby reducing the stress and pressure caused by the length change, and helping to protect the structural integrity of the pipe or equipment.

[0003] When the existing non-metallic expansion joint expands, the internal non-metallic bellows are not protected by multi-directional buffering. The lack of multi-directional buffering protection means that the non-metallic bellows may be affected by uneven forces when expanding, increasing the risk of deformation, causing the non-metallic bellows to twist, deform or even rupture, thereby affecting the normal operation of the pipeline system or equipment. Without sufficient support, the non-metallic bellows are easily damaged by the external environment, vibration or pressure. This may lead to leakage or complete failure, posing a potential threat to the safety and reliability of the system. The deformation of the non-metallic bellows may cause the performance of the system to decline, such as fluid flow instability, increased pressure loss, etc., affecting the normal operation and work efficiency of the pipeline system or equipment.

[0026] Embodiment 3

[0027] refer to Figure 1 , Figure 3 and Figure 4The utility model discloses a multi-directional buffer structure for a non-metallic expansion joint, including a non-metallic expansion joint body 1 with a non-metallic bellows 3 arranged inside, two flanges 2 arranged inside the non-metallic expansion joint body 1, the two end surfaces of the non-metallic bellows 3 correspondingly fixedly connected with the inner surfaces of the two flanges 2, a sealing clamping assembly installed inside a sealing block 15, one end surface of the two sealing blocks 15 are both installed with a sealing strip 16, the outer surface of the sealing strip 16 is in active contact with the inner surface of the airtight cavity 6, the outer surface of the sealing block 15 is installed with a gas nozzle 14, the sealing clamping assembly includes two clamping cavities 17 and two third springs 20, the two clamping cavities 17 are opened inside the sealing block 15, and the two third springs 20 are correspondingly installed in the clamping cavity 1 7, one end surface of the two third springs 20 are both installed with sealing rings 19, the outer surface of the sealing ring 19 is in active contact with the inner wall of the card cavity 17, and the outer surface of the sealing ring 19 is in active contact with the inner wall of the airtight cavity 6. The elastic deformation of the third spring 20 can ensure that the sealing ring 19 is always tightly fitted to the airtight cavity 6 during the movement of the sealing chuck, thereby improving the sealing performance of the system. It is very important to strictly control the application of gas flow, especially in the process of expansion and movement of the sealing chuck.

[0028] The working principle and use process of the utility model are as follows: when the non-metallic expansion joint body 1 is needed, the non-metallic expansion joint body 1 needs to be connected when it is installed, and the threaded rod 7 is inserted from the two first fixing blocks 4, and the hexagonal nut 8 is threadedly rotated to be connected to the threaded rod 7, and the hexagonal nut 8 is continuously rotated to be in active contact with the first fixing block 4. The hexagonal nut 8 is threadedly connected to the threaded rod 7 to ensure the reliability of the fixation of the non-metallic expansion joint body 1 and the pipeline system. The rotation connection of the hexagonal nut 8 can effectively fix the threaded rod 7, making it difficult to loosen or fall off, thereby ensuring the stability and safety of the non-metallic expansion joint body 1 during operation.

[0029] When the non-metallic expansion joint body 1 is working, when the non-metallic bellows 3 is affected by the thermal expansion and contraction caused by the temperature change of the pipeline system, the shape will change. At high temperature, the non-metallic bellows 3 may expand and expand, and at low temperature it will contract. This shape change is to absorb the length change of the pipeline system caused by the temperature change. When the non-metallic expansion joint body 1 changes, the non-metallic expansion joint body 1 drives the second fixed block 5 to change slightly, and the second fixed block 5 drives the telescopic slot 9 to change slightly, the baffle 10 and the lifting column 11 move in the telescopic slot 9, and the second fixed block 5 stretches the first spring 12, and the lifting column 11 synchronously drives the sealing block 15 and the sealing strip 16 to move in the airtight cavity 6, and the second fixed blocks 5 at both ends expand and move, causing the sealing blocks 15 at both ends to move slightly synchronously, and causing the two sealing blocks 15 to stretch synchronously. The second spring 18 and the sealing block 15 synchronously drive the sealing strip 16 to move in the airtight cavity 6, so that the airtightness inside the airtight cavity 6 of the buffer sealing block 13 is good, and the multiple lifting columns 11 move and the first spring 12 and the second spring 18 have elastic deformation, and then cooperate with the gas inside the airtight cavity 6 of the buffer sealing block 13 to achieve multi-directional buffering of the non-metallic bellows 3. Through the movement of multiple lifting columns 11, support is provided for the non-metallic bellows 3 in all directions, thereby ensuring its stability and safety during operation. The elastic deformation of the first spring 12 and the second spring 18 enables the system to buffer the external pressure or vibration of the non-metallic bellows 3, thereby extending the service life of the non-metallic bellows 3 and reducing maintenance costs, protecting the non-metallic bellows 3, and providing effective support and buffering without damaging the structure of the non-metallic bellows 3.

[0030] And when the sealing chuck is moving, the third spring 20 has elastic deformation, so that the sealing ring 19 fits tightly against the airtight chamber 6, so that the sealing chuck always maintains the sealing inside the airtight chamber 6 during the expansion and movement, and the airtight chamber 6 can be filled with gas through the air nozzle 14. The elastic deformation of the third spring 20 can ensure that the sealing ring 19 always fits tightly against the airtight chamber 6 during the movement of the sealing chuck, thereby improving the sealing performance of the system. It is very important to strictly control the application of gas flow, especially in the process of expansion and movement of the sealing chuck. The function of the third spring 20 can ensure that the sealing inside the airtight chamber 6 is not affected and prevent gas leakage. Filling gas into the airtight chamber 6 through the air nozzle 14 makes it more convenient to maintain and adjust the internal pressure or gas composition of the airtight chamber 6.
