Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline sealing technology, and in particular to a leak-proof sealing structure for long pipe connections. Background Technology
[0002] In modern industry, long pipes are widely used in petroleum, chemical, natural gas transmission, and water supply and drainage systems. As a key link in the construction of pipeline systems, the sealing performance of long pipes directly determines the operational stability and safety of the entire system. Effective sealing of long pipes is a necessary prerequisite for ensuring the safe, stable, and efficient operation of industrial production.
[0003] The most common sealing structure today is the gasket seal. The main structure consists of a gasket with a certain degree of elasticity, such as a rubber or metal spiral wound gasket, placed between two flanges. During operation, the flanges are tightened with bolts, causing the gasket to be compressed and deformed elastically, filling the tiny gaps between the flange sealing surfaces and preventing media leakage.
[0004] Currently, conventional gasket sealing in long pipe connection operations requires multiple steps to precisely align the gaskets and tighten a large number of bolts. The process is cumbersome and prone to poor sealing due to operational errors, and it is also time-consuming. Therefore, a leak-proof sealing structure for long pipes is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a leak-proof sealing structure for long pipe connections, aiming to improve the problem of complex and time-consuming connection operations for long pipe connections in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] The long pipe leak-proof sealing structure includes a fixing block one, an adjustment component inside the fixing block one, a fixing block two fixedly connected to the top of the fixing block one, a control component inside the fixing block two, a docking block fixedly connected to the outside of the fixing block one, a rotating screw two threadedly connected to the outside of the docking block, a connecting pipe rotatably connected inside the rotating screw two, a fixing block three fixedly connected to the outside of the connecting pipe, and a sealing gasket on the outside of the fixing block three.

[0010] As a further description of the above technical solution:
[0011] The adjustment assembly includes a limiting block, the outside of which is fixedly connected to the inside of the fixing block, an adjustment cylinder is slidably connected inside the limiting block, a flow groove is provided on the outside of the adjustment cylinder, a transmission rod is rotatably connected to the outside of the adjustment cylinder, and a rotating rod is rotatably connected to the end of the transmission rod away from the adjustment cylinder.
[0012] As a further description of the above technical solution:
[0013] The control component includes a rotating column, the outside of which is rotatably connected to the inside of the fixed block two, a guide tooth fixedly connected to the outside of the rotating column, a rotating screw one threadedly connected to the outside of the fixed block two, and the outside of which is slidably connected to the inside of the rotating screw one.

[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, regarding the sealing of the long pipe connection, the operator first slides the pipe into the connection block, then rotates the rotating screw. The rotating screw moves outside the connection block, pushing the pipe further in. The connection block gradually contacts the sealing gasket. The rotating screw is continuously rotated until it can no longer be rotated. At this point, the connection block and the sealing gasket are tightly fitted, and the cavity between the fixed block and the rotating screw is filled by the deformed sealing gasket, successfully achieving a seal, completing the pipe connection, ensuring normal pipe use, effectively preventing leakage, and ensuring safe transportation.
[0024] 2. In this utility model, after the operator connects the two connecting pipes through the fixed block, the operator rotates the rotating screw. The rotating screw moves outside the fixed block, causing the guide teeth to slide in the sliding groove, thereby controlling the rotating column to rotate inside the fixed block. The rotation of the rotating column drives the rotating rod, which in turn drives the transmission rod. The transmission rod causes the adjusting cylinder to slide within the limiting block, changing the flow range of the flow channel and realizing the adjustment of the liquid flow rate inside the fixed block. This allows for quick adaptation to the flow rate requirements of different scenarios and improves the flexibility of use. Attached Figure Description

[0031] 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.
[0032] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a long pipe leak-proof sealing structure, including a fixing block 1, which is an important basic component of the entire sealing structure, serving to connect and fix other components. An adjustment component is provided inside the fixing block 1 to adjust the liquid flow rate within the long pipe to adapt to different usage scenarios. A fixing block 2 7 is fixedly connected to the top of the fixing block 1, and the fixing block 2 7 is tightly connected to the fixing block 1. A control component is provided inside the fixing block 2 7, which is the key part for realizing flow adjustment operation. The operator controls the operation of the adjustment component through it. A docking block 12 is fixedly connected to the outside of the fixing block 1. The docking block 12 is used to dock with the pipe and is an important interface component for pipe connection. A rotating screw 2 13 is threadedly connected to the outside of the docking block 12. A connecting pipe 14 is rotatably connected inside the rotating screw 2 13. The rotating screw 2 13 engages with the docking block 12 through its threads, allowing for adjustment of the position of the connecting pipe 14.
[0033] The connecting pipe 14 is part of the long connecting pipe and is used to connect the pipes and transport fluids. The connecting pipe 14 is externally fixedly connected to a fixing block 3 15, which serves to fix and assist in sealing. A sealing gasket 16 is provided on the outside of the fixing block 3 15. The sealing gasket 16 works together to achieve a good sealing effect. The sealing gasket 16 is the key component to achieve the seal. It fills the gap through its deformation to prevent fluid leakage. The outside of the connecting pipe 14 is slidably connected to the inside of the connecting block 12. This sliding connection method allows the connecting pipe 14 to be smoothly inserted into the connecting block 12, which is convenient for installation. The end of the sealing gasket 16 away from the fixing block 3 15 is in contact with the outside of the connecting block 12. During the installation process, the sealing gasket 16 will fit tightly with the connecting block 12 to achieve a seal.
[0034] The fixed block 3 15 is L-shaped. The L-shaped design allows the fixed block 3 15 to better cooperate with the rotating screw 2 13 and the sealing gasket 16, enhancing the sealing effect. The external rotating connection of the fixed block 3 15 is inside the rotating screw 2 13. This connection method ensures the rotational flexibility of the fixed block 3 15 inside the rotating screw 2 13, and also helps the sealing operation. The external fixed connection of the fixed block 1 1 is another docking block 12. The two docking blocks 12 are symmetrically arranged to facilitate docking with the two connecting pipes 14 to realize the connection of the long connecting pipe. The external sliding connection of the regulating cylinder 3 is inside the other docking block 12. The sliding connection of the regulating cylinder 3 provides the conditions for its movement inside the limiting block 2, thereby realizing the flow regulation.
[0035] Reference Figures 1 to 3The regulating component includes a limiting block 2, which is fixed inside a fixed block 1. An regulating cylinder 3 is slidably connected inside the limiting block 2. The function of the limiting block 2 is to limit the regulating cylinder 3, ensuring it can only slide within a specific direction and range. The limiting block 2 is externally fixedly connected inside the fixed block 1, and the tight connection between the limiting block 2 and the fixed block 1 guarantees the stability of its limiting function. The regulating cylinder 3 slides inside the limiting block 2, changing the position of the flow channel 4 to achieve flow regulation. The regulating cylinder 3 has a flow channel 4 on its external side. The through groove 4 is a channel for liquid flow. Changes in its shape and position will affect the flow rate of the liquid. The external part of the regulating cylinder 3 is rotatably connected to the transmission rod 5. The transmission rod 5 is rotatably connected to the regulating cylinder 3. The rotation of the transmission rod 5 drives the sliding of the regulating cylinder 3. The end of the transmission rod 5 away from the regulating cylinder 3 is rotatably connected to the rotating rod 6. The rotating rod 6 is connected to the transmission rod 5 and transmits the rotation of the subsequent rotating column 9 to the transmission rod 5, thereby driving the movement of the regulating cylinder 3. The control component includes the rotating column 9. The rotating column 9 is the core component of the control component. The rotation of the rotating column 9 realizes the control of the regulating cylinder 3.
[0036] The rotating column 9 is externally rotatably connected to the interior of the fixed block 7, allowing it to rotate flexibly within the block. A guide tooth 10 is fixedly connected to the outside of the rotating column 9, moving with its rotation. This guide tooth 10 engages with the rotating screw 8 for control. The fixed block 7 is threadedly connected to the outside of the rotating screw 8, allowing the operator to control the rotation of the rotating column 9 by rotating the screw 8. The guide tooth 10 is externally slidably connected to the interior of the rotating screw 8, enabling precise control of the rotation of the rotating column 9. The rotating column 9 is externally rotatably connected to the inside of the fixed block 1. The rotatable connection between the rotating column 9 and the fixed block 1 ensures the stability and reliability of its rotation. The rotating rod 6 is externally fixedly connected to the inside of the rotating column 9. The rotating rod 6 is tightly connected to the rotating column 9 and can accurately transmit the rotation of the rotating column 9 to the transmission rod 5. The flow groove 4 is triangular in shape. The triangular shape design makes the flow groove 4 have a good effect when regulating the flow rate and can achieve more precise flow control. The rotating screw 8 has a sliding groove 11 inside. The sliding groove 11 provides a track for the sliding of the guide tooth 10, ensuring the accuracy and stability of the rotation of the rotating column 9.
[0037] Working principle: When the operator needs to connect the long pipe, the connecting pipe 14 is slid into the connecting block 12. At this time, by rotating the rotating screw 13, the connecting pipe 14 will gradually move into the connecting block 12 as the rotating screw 13 moves outside the connecting block 12. This causes the outside of the connecting block 12 to gradually contact the outside of the sealing gasket 16 until the rotating screw 13 can no longer be turned. At this time, the connecting block 12 will be tightly fitted with the sealing gasket 16. At the same time, the cavity between the fixing block 15 and the rotating screw 13 will be filled by the deformed sealing gasket 16, finally achieving a sealing effect. This completes the sealing connection of the pipeline and ensures the normal use of the pipeline.
[0038] After the operator connects the two connecting pipes 14 through the fixed block 1, they can rotate the rotating screw 8. When the rotating screw 8 moves outside the fixed block 2, the guide tooth 10 slides inside the sliding groove 11, thereby controlling the rotating column 9 to rotate inside the fixed block 1. The rotation of the rotating column 9 causes the rotating rod 6 to drive the transmission rod 5 to rotate, thereby causing the adjusting cylinder 3 to slide inside the limiting block 2, thus adjusting the flow range of the flow groove 4, and finally realizing the adjustment of the liquid flow rate inside the fixed block 1. Through rapid flow adjustment, the needs of different scenarios can be met.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
