Description

Technical Field

[0001] This utility model relates to the field of natural gas pipeline construction technology, and more specifically, to a reusable sealing tool. Background Technology

[0002] During the construction of medium and low pressure buried natural gas pipelines, when encountering trenchless connection operations or special circumstances requiring leaving the construction site, in order to prevent foreign objects such as water, dead branches and leaves, and small stones from entering the pipeline, and to ensure that the pipeline can be pressurized during the connection work so as to detect whether the pipeline is damaged in time, it is usually necessary to temporarily seal the pipeline.

[0003] Currently, common temporary sealing methods have many drawbacks. On the one hand, although pipe cap temporary sealing is readily available and low-cost, meeting the needs of emergency use, its sealing performance is poor, making it difficult to effectively prevent foreign objects from entering the pipeline and failing to meet the requirements of long-term sealing and strict pressure maintenance. On the other hand, although PE pipe fitting temporary sealing has good sealing performance and safety, it is expensive, time-consuming to install, and requires electricity, making it highly dependent on usage conditions. It cannot be implemented smoothly when there is no power supply at the construction site. These problems not only reduce construction efficiency but may also cause pipeline damage due to inadequate sealing, resulting in unnecessary economic losses and increased operating costs for enterprises.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0007] A reusable plugging tool includes a sealing assembly with a limiting component. A tube is provided on one side of the sealing assembly. The sealing assembly includes a plugging diaphragm. An adjusting diaphragm is provided on one side of the plugging diaphragm and is located inside the tube. Multiple expanding diaphragms are connected to the adjusting diaphragm, and one end of the expanding diaphragm and one side of the plugging diaphragm are in contact with the tube.

[0008] Furthermore, in order to better ensure the sealing effect, a first gasket and a second gasket are embedded in both ends of the sealing membrane and the adjusting membrane, and the first gasket and the second gasket are compatible with the sealing membrane and the adjusting membrane.

[0009] Furthermore, to better ensure the adjustment effect, the first and second shims are equipped with screws via bearings. One end of the screw is movably connected to a plug, and the other end of the screw is equipped with a bolt, which is compatible with the screw.

[0010] Furthermore, to better ensure the limiting effect, the limiting component includes a ratchet, which is fixedly mounted on the plug. A pawl is engaged with the ratchet, and a tension spring is provided on one side of the pawl. Both the pawl and the tension spring are connected to one side of the first washer via a rotating shaft.

[0011] Furthermore, to better ensure the limiting effect of the bolt, a mounting bracket is provided on the bolt, and multiple telescopic rods are embedded in the mounting bracket. The moving end of the telescopic rod is provided with an adjustment block.

[0012] Furthermore, to better ensure the auxiliary movement effect, an adjustment groove is provided at one end of the adjustment block, and an auxiliary wheel is connected inside the adjustment groove.

[0025] 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.

[0026] Example 1:

[0027] like Figures 1-8 As shown, a reusable sealing tool according to an embodiment of the present invention includes a sealing component 1, a limiting component 2 on the sealing component 1, a tube body 3 on one side of the sealing component 1, a sealing membrane 101, an adjusting membrane 102 on one side of the sealing membrane 101, and the adjusting membrane 102 is located inside the tube body 3. A plurality of expanding membranes 103 are connected to the adjusting membrane 102, and one end of the expanding membrane 103 and one side of the sealing membrane 101 are in contact with the tube body 3. The adjusting membrane 102, the adjusting membrane 102, and the expanding membrane 103 are all made of rubber.

[0028] The sealing membrane 101 and the adjusting membrane 102 are fitted with a first gasket 104 and a second gasket 105 at both ends, and the first gasket 104 and the second gasket 105 are adapted to the sealing membrane 101 and the adjusting membrane 102. The first gasket 104 and the second gasket 105 are provided with a screw 106 through a bearing. One end of the screw 106 is movably connected to a plug 107. One end of the plug 107 is set with an internal hexagonal structure, which is adjusted by an external hexagonal wrench in actual use. The other end of the screw 106 is provided with a bolt 108, and the bolt 108 is adapted to the screw 106.

[0029] Example 2:

[0030] like Figures 1-8 As shown, according to an embodiment of the present invention, a reusable sealing tool includes a limiting component 2 comprising a ratchet 201, which is fixedly mounted on a plug 107. A pawl 202 is engaged with the ratchet 201, and a tension spring 203 is provided on one side of the pawl 202. Both the pawl 202 and the tension spring 203 are connected to one side of a first gasket 104 via a rotating shaft. A mounting bracket 204 is provided on a bolt 108, and multiple telescopic rods 205 are embedded in the mounting bracket 204. An adjusting block 206 is provided at the moving end of each telescopic rod 205, and an adjusting groove is provided at one end of the adjusting block 206. An auxiliary wheel 207 is connected inside the adjusting groove.

[0031] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0032] In summary, with the help of the above-mentioned technical solution of this utility model, when it is necessary to seal a pipeline, the sealing tool is first inserted into the pipe body 3. At this time, the sealing diaphragm 101, the adjusting diaphragm 102, and the expanding diaphragm 103 come into contact with the pipe body 3 and begin to perform a sealing function. At the same time, the plug 107 is rotated by an external hex wrench, which causes the screw 106 to drive the bolt 108 to rotate along the thread, thereby causing the adjusting diaphragm 102 to contract. The specific principle is the principle of air pressure change, which is a conventional technical means. This causes the expanding diaphragm 103, which is in a contracted state, to expand (e.g., Figure 3 , 4 As shown), this makes it fit more tightly against the tube body 3, enhancing the sealing effect. At this time, the ratchet 201 rotates as the plug 107 moves, and the pawl 202 remains engaged with the ratchet 201 under the action of the tension spring 203, preventing the plug 107 from loosening and ensuring the reliability of the sealing.

[0033] During installation or disassembly, the telescopic rod 205 can be extended or retracted as needed, which drives the adjustment block 206 to move and the auxiliary wheel 207 to roll in the adjustment groove, assisting in the installation and positioning of the entire sealing tool and ensuring that the tool and the pipe body 3 are tightly and stably matched.

[0034] When it is necessary to remove the seal, rotate the plug 107 in the opposite direction. The screw 106 will drive the plug 107 to move in the opposite direction. The sealing membrane 101, adjusting membrane 102 and expanding membrane 103 will gradually loosen their fit with the tube body 3, and the sealing tool can be removed from the tube body 3.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
