Description

Technical Field

[0001] This utility model belongs to the field of electromechanical engineering technology, and specifically relates to a pipeline sealing device. Background Technology

[0002] In electromechanical engineering, which involves the construction of outdoor and indoor pipelines, the first step is to install the pipeline section at the exit point during the main construction phase. Then, the two sides of the pipeline exit point are sealed to prevent outdoor rainwater from flowing back into the basement.

[0003] In the existing technology, there are two conventional sealing techniques. The first is to use steel plate welding, which is suitable for welding steel pipes. It is costly and cannot be repaired by welding when there is leakage. The second is ordinary pipe plug, which is low-cost and quick to operate, but it cannot effectively stop leakage when it occurs.

[0026] Example 1

[0027] A specific embodiment of this utility model is as follows: Figure 1-2 As shown, a pipeline plugging device is disclosed, comprising:

[0028] Plug 1, used to seal pipeline openings;

[0029] The sealing ring assembly 2 includes a connecting pipe 21 and a sealing ring 22. One end of the connecting pipe 21 is detachably connected to the sealing head 1, and the sealing ring 22 is sleeved on the outer wall of the connecting pipe 21.

[0030] A plugging ball 3 is disposed at the end of the connecting pipe 21 away from the plugging head 1. The plugging ball 3 is configured to adjust the size of the plugging ring 22 by moving within the connecting pipe 21.

[0031] During implementation, the pipeline sealing device, consisting of a sealing ball, is inserted into the pipeline to be sealed. The outer diameter of the sealing head is slightly larger than the inner diameter of the pipeline opening, used to seal the outermost opening of the pipeline. The size of the sealing ball is slightly larger than the inner diameter of the connecting pipe. By adjusting the position of the sealing ball, the sealing ring expands radially, thus tightly fitting against the inner wall of the pipeline. This achieves three layers of sealing: the sealing ball seals the internal channel of the connecting pipe, the sealing ring seals the annular gap between the connecting pipe and the pipeline, and the sealing head completes the outermost basic seal. ...

[0032] In this embodiment, the sealing head 1 is provided with a through hole for the screw 31 to pass through. One end of the screw 31 is fixedly connected to the sealing ball 3, and the other end passes through the through hole to adjust the position of the sealing ball 3.

[0033] In this embodiment, a nut 32 adapted to the screw 31 is provided at the through hole to adjust the position of the sealing ball 3 in the connecting pipe 21.

[0034] For example, the inner wall of the central through hole of the plugging head 1 is provided with an internal thread, which matches the external thread of the screw 31 to form an adjustable linear motion mechanism. The position of the plugging ball 3 in the connecting pipe 21 is then adjusted by turning the nut 32.

[0035] In this embodiment, the sealing head 1 is provided with a baffle 11 inside, and the baffle 11 is made of plastic or steel.

[0036] For example, it is made of high-strength plastic or steel and embedded inside the sealing head 1 through a hot-melt process to enhance the support of the sealing head.

[0037] In this embodiment, the materials of the connecting pipe 21 and the sealing ring 22 include plastic.

[0038] For example, the connecting pipe 21 and the sealing ring 22 are made of high-temperature resistant and corrosion-resistant plastic. The thickness of the pipe wall and the thickness of the sealing ring can be designed according to the actual situation to ensure sealing.

[0039] In this embodiment, the diameter of the sealing ball 3 is equal to the diameter at the port of the connecting pipe 21.

[0040] For example, the connecting pipe 21 can be configured such that the diameter of the port near the sealing ball 3 is equal to the diameter of the sealing ball 3, and the diameter decreases from near the sealing ball 3 to near the sealing head 1. Correspondingly, the diameter of the sealing ring 22 increases from near the sealing ball 3 to near the sealing head 1, thereby enabling the sealing device to adjust the squeezing force generated by the sealing ball 3 according to different water pressure conditions.

[0041] In this embodiment, the number of sealing rings 22 is: Spacing is l represents the length of the connecting pipe 21, and r represents the diameter of the connecting pipe 21.

[0042] Specifically, experimental tests showed that the number and spacing of the sealing rings 22 affect the sealing effect and are closely related to the diameter of the connecting pipe 21. Therefore, the number and spacing of the sealing rings 22 are set to the above-mentioned state to improve the sealing performance.

[0043] In this embodiment, the screw 31 has a position mark for determining the position of the sealing ball 3 inside the connecting pipe 21.

[0044] For example, the screw 31 has a laser scale on its surface. When the distance between the sealing ball 3 and the sealing head 1 is the farthest, the scale is 0, which makes it easy to clearly perceive the position of the sealing ball 3 in the connecting tube 21.

[0045] Compared with the prior art, the pipeline plugging device provided in this embodiment adjusts the position of the plugging ball to make the plugging ring expand radially, thereby making it tightly fit with the inner wall of the pipeline. This achieves three-layer sealing: the plugging ball blocks the internal channel of the connecting pipe, the plugging ring blocks the annular gap between the connecting pipe and the pipeline, and the plugging head completes the outermost basic seal, thus effectively preventing leakage.

[0046] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
