Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, and specifically relates to a thermal pipeline connection structure. Background Art

[0002] The existing connection of thermal pipelines is only connected to external pipelines through simple rotation, resulting in poor connection stability, poor sealing effect, and leakage of thermal pipelines will cause energy waste, affect user heating, and increase the maintenance burden. The influencing factors include poor welding quality, too high water pressure, loose pipeline sealing, insufficient strength of the connection structure. Due to the high temperature of the fluid transported in the pipeline, thermal pipelines will experience thermal expansion and contraction. The traditional welding and fixing method is prone to damage to pipelines and supports, posing potential safety hazards.

[0003] The prior art has the following defects or problems: In the prior art, the publication number is: CN218236486U, a thermal pipeline connection structure, including a socket, a spigot, and a telescopic retaining ring. The socket and the spigot are respectively arranged at both ends of the pipeline body. The spigot is inserted into the socket and fixed in a self-anchoring manner through the telescopic retaining ring. The outer periphery of the spigot is sequentially provided with a frustum and a retaining platform from the end to the inner side. The center of the spigot communicates with the pipeline inner cavity of the pipeline body. The center of the spigot is sequentially provided with an outer hole, a retaining groove, an inner hole, and a tapered hole from the end to the inner side. The tapered hole communicates with the pipeline inner cavity. The telescopic retaining ring is an annular shape that can expand and contract in the diameter direction. The cross-section of the annular telescopic retaining ring is sequentially composed of a left straight surface, an inclined surface, an inner straight surface, a right straight surface, and an outer straight surface. The telescopic retaining ring is installed in the retaining groove. This pipeline interface structure can ensure that the thermal pipeline (ductile iron pipeline) can produce an anti-pulling effect after connection, and can effectively avoid leakage in the case of installing a pier without wind.

[0004] During the use of the above equipment, it is difficult to fix the pipeline interface, and small gaps or looseness are likely to occur at the interface, which will cause gas leakage in the pipeline and damage other components of the pipeline system, shortening the service life of the entire system. In the prior art, under the state of thermal expansion and contraction of some thermal pipelines, the support structure of the pipeline system will fail, thereby triggering dangerous situations such as pipeline collapse.

[0005] It should be noted that the above content belongs to the technical cognition scope of the inventor and does not necessarily constitute the prior art. Content of the Utility Model

[0009] As a preferred technical solution of the present utility model, the top end of the first fixing ring is in contact with the bottom end of the second fixing ring. The inner wall of the nut is threadedly connected to the outside of the nut.

[0010] As a preferred technical solution of the present utility model, the outside of the right side of the second fixing ring is fixedly connected to the outside of the left side of the sleeve. The inside of the sleeve is rotatably connected to the outside of the rotating shaft.

By setting a first fixing ring, a connecting plate, a rotating shaft, a sleeve, a second fixing ring, an extension plate, a nut, a screw cap, and a sealing groove, when the second fixing ring approaches the first fixing ring, the second fixing ring will drive the sleeve to rotate outside the rotating shaft, so that the second fixing ring contacts the first fixing ring. Then insert the nut into the inside of the extension plate, and finally tighten the screw cap, so that the device can fix and seal two thermal pipelines, which helps to improve the safety of the entire thermal pipeline system, protect the equipment from damage, and ensure the safety of the staff.

[0017] 2. A thermal pipeline connection structure. By setting an inlay groove, a fixing block, an inner cavity, a contact plate, a slider, a spring, and a sliding groove, when an external force acts on the pipeline, the external force will be transmitted to the inside of the fixing block through the contact plate, causing the contact plate to slide inside the fixing block, and the contact plate drives the slider to slide, and the contact plate compresses the spring. Through the elasticity of the spring, it can effectively reduce the action of the external force on the pipeline and protect the pipeline from damage. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4, in this implementation: A thermal pipeline connection structure includes a first fixing ring 1 and a second fixing ring 5. The top end of the first fixing ring 1 is in contact with the bottom end of the second fixing ring 5. A connecting plate 2 is fixedly connected to the right side of the first fixing ring 1. A rotating shaft 3 is fixedly connected inside the connecting plate 2. The inside of a sleeve 4 is rotatably connected to the outside of the rotating shaft 3. The outside of the rotating shaft 3 is rotatably connected to the sleeve 4. The outside of the sleeve 4 is fixedly connected to the second fixing ring 5. The outside of the right side of the second fixing ring 5 is fixedly connected to the outside of the left side of the sleeve 4. A prolonging plate 6 is fixedly connected to the left side of the second fixing ring 5. A plurality of nuts 7 are threadedly connected inside the prolonging plate 6. The inner wall of a nut 8 is threadedly connected to the outside of the nut 7. The outsides of the plurality of nuts 7 are respectively threadedly connected to the nut 8. A gasket 17 is arranged at the bottom end of the prolonging plate 6. Two embedding grooves 9 are respectively formed inside the first fixing ring 1 and the second fixing ring 5. Sealing grooves 10 are respectively formed inside the first fixing ring 1 and the connecting plate 2. A plurality of shock-absorbing components are fixedly connected inside the first fixing ring 1.

[0025] In this embodiment, when the second fixing ring 5 is brought close to the first fixing ring 1, the second fixing ring 5 will drive the sleeve 4 to rotate outside the rotating shaft 3, so that the second fixing ring 5 contacts the first fixing ring 1. Then, the nut 7 is inserted into the inside of the prolonging plate 6. By tightening the nut 8, the connection structure can be further strengthened to ensure its firmness. The first fixing ring 1 and the second fixing ring 5 are the basic parts of the connection structure, providing a preliminary fixing effect through mutual contact, and the two form a basic docking surface. The gasket 17 is used to increase the contact area and disperse the pressure, thereby improving the stability and sealing performance of the connection.

[0026] Embodiment Two

[0027] As Figure 1 - Figure 4 shown, the plurality of shock-absorbing components respectively include fixing blocks 11. The outsides of the plurality of fixing blocks 11 are respectively fixedly connected inside the embedding grooves 9. An inner cavity 12 is formed inside the fixing blocks 11. A contact plate 13 is slidably connected inside the fixing blocks 11. The outsides of the plurality of contact plates 13 are respectively slidably connected to the inner walls of the plurality of fixing blocks 11. Slide blocks 14 are respectively fixedly connected to the left and right sides of the contact plate 13. The outside of the slide blocks 14 is slidably connected to the inner wall of a chute 16. Chutes 16 are respectively formed on the left and right inner walls of the fixing blocks 11. A plurality of springs 15 are fixedly connected inside the first fixing ring 1. The top ends of the plurality of springs 15 are fixedly connected to the bottom end of the contact plate 13. The bottom ends of the plurality of springs 15 are respectively fixedly connected to the bottom inner wall of the fixing blocks 11.

[0028] In this embodiment, when the heat pipeline is operating, due to fluid pressure changes or external environmental influences, the pipeline will generate vibrations and impact forces. These forces will be transmitted to the contact plate 13 through the fixing block 11, causing the contact plate 13 to slide within the inner cavity 12 of the fixing block 11 and compress the spring 15. The elastic action of the spring 15 can absorb part of the energy and reduce the impact force on the connection structure.

[0029] The working principle and usage process of the present utility model: When the second fixing ring 5 approaches the first fixing ring 1, the second fixing ring 5 will drive the sleeve 4 to rotate outside the rotating shaft 3, so that the second fixing ring 5 contacts the first fixing ring 1. Then, insert the nut 7 into the inside of the extension plate 6, and further reinforce the connection structure by tightening the nut 8 to ensure its firmness. The first fixing ring 1 and the second fixing ring 5 are the basic parts of the connection structure, providing a preliminary fixing effect through mutual contact, and the two form a basic docking surface. The gasket 17 is used to increase the contact area and disperse the pressure, thereby improving the stability and sealing performance of the connection. When the heat pipeline is operating, due to fluid pressure changes or external environmental influences, the pipeline will generate vibrations and impact forces. These forces will be transmitted to the contact plate 13 through the fixing block 11, causing the contact plate 13 to slide within the inner cavity 12 of the fixing block 11 and compress the spring 15. The elastic action of the spring 15 can absorb part of the energy and reduce the impact force on the connection structure, thereby protecting the stability and safety of the entire system.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they 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 utility model shall be included within the protection scope of the present utility model.
