Description

Technical Field

[0001] The utility model relates to the technical field of pipeline plugging, and in particular to a high-efficiency pipeline sealing plug. Background Art

[0002] Pipeline systems are an integral part of modern industrial production and urban construction. Whether in water treatment, chemical production, or urban gas and water supply, pipes are widely used to transport liquids or gases. If a leak occurs in a piping system, a plug can be used to temporarily stop the pipe from leaking, preventing unnecessary water loss. During pipeline repair or replacement, a plug can be used to temporarily close the pipe to prevent fluid loss and environmental pollution. In certain work scenarios, plugs are needed to seal and close the pipe to prevent liquid or gas leakage. Therefore, pipe sealing technology is particularly important.

[0003] Currently, most of the pipe sealing plugs available on the market use physical compression to achieve sealing, such as knocking a conical plug into the pipe through inward axial force. Although this method is simple and direct, it has many problems in actual operation. First, the installation and removal process is time-consuming and labor-intensive, especially when working in a narrow space. Second, long-term use may cause damage to the inner wall of the pipe, affecting the service life of the pipe. Finally, once a leak occurs and the plug needs to be replaced, the original plug is often difficult to remove completely, and sometimes even the pipe needs to be destroyed to remove it. This not only increases maintenance costs, but also greatly reduces work efficiency, especially in emergency repair situations. Utility Model Content

[0041] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0042] like Figure 1-8 As shown, a high-efficiency pipeline sealing plug includes: a pipeline 1, a front blocking mechanism 2 inserted into the pipeline 1, a supporting and blocking component 3 provided on the front blocking mechanism 2, and a tightening component 4 installed on the outer wall of the pipeline 1;

[0043] The tightening assembly 4 is located in front of the front blocking mechanism 2 and the supporting and blocking assembly 3, and the tightening assembly 4 is connected to the supporting and blocking assembly 3, wherein:

[0044] The front blocking mechanism 2 can block the inside of the pipeline 1 to cut off the inside of the pipeline 1;

[0045] The supporting and blocking component 3 is adapted to be expanded in four directions and then pressed against the inner wall of the pipe 1 so as to be closely attached to the rear of the front blocking mechanism 2 and partially cut off the interior of the pipe 1 again;

[0046] The tightening component 4 is suitable for tightening the supporting and blocking component 3 with the help of the pipeline 1 to fix the front blocking mechanism 2 and the supporting and blocking component 3. The high-efficiency pipeline sealing plug can quickly form a preliminary blocking layer in the pipeline 1 through the front blocking mechanism 2, thereby using this as the main blocking layer to ensure that a whole cross-section is formed to cut off the inside of the pipeline 1. After the front blocking mechanism 2 is installed in place, the supporting and blocking component 3 can continue to expand on the back of the front blocking mechanism 2 until it is pressed against the inner wall of the pipeline 1, thereby forming a blockage at the intersection with the pipeline 1 again immediately after the front blocking mechanism 2, effectively enhancing the sealing performance and ensuring the sealing effect. The tightening component 4 can firmly tighten the front blocking mechanism 2 and the supporting and blocking component 3 after the sealing is completed based on the pipeline 1, thereby ensuring that they are fixed and secured. The invention relates to a pipe sealing device 1 which is provided with a plurality of sealing assemblies 1 and a plurality of sealing assemblies 3. The pipe sealing device 1 is provided with a plurality of sealing assemblies 1 and a plurality of sealing assemblies 3. The sealing assemblies 1 are provided with a plurality of sealing assemblies 1 and a plurality of sealing assemblies 3. The sealing assemblies 1 are provided with a plurality of sealing assemblies 1 and a plurality of sealing assemblies 3. The sealing assemblies 1 are provided with a plurality of sealing assemblies 1 and a plurality of sealing assemblies 3. The sealing assemblies 1 are provided with a plurality of sealing assemblies 1 and a plurality of sealing assemblies 3. The sealing assemblies 1 are provided with a plurality of sealing assemblies 1 and a plurality of sealing assemblies 3.

[0047] Optionally, the front blocking mechanism 2 includes a main blocking disk 21, a sealing ring 22 integrally mounted on the periphery of the main blocking disk 21, a guide column 23 mounted on the back of the main blocking disk 21 and located in the center of the main blocking disk 21, a pushing handle 24 connected to the tail of the guide column 23, and a front thorn ring 25 mounted on the edge of the main blocking disk 21;

[0048] The front thorn ring 25 is located directly in front of the sealing ring 22;

[0049] The diameter of the sealing ring 22 is larger than the inner diameter of the pipe 1. Hold the pushing handle 24 and push the main blocking disk 21 into the pipe 1 to be blocked until it is inserted into the appropriate position. During the insertion process, the sealing ring 22 and the main blocking disk 21 are used to block the inside of the pipe 1, thereby forming a preliminary blocking layer to cut off the inside of the pipe 1 and block it; the front thorn ring 25 indirectly extends the intersection distance between the sealing ring 22 and the inner wall of the pipe 1, and uses the front thorn ring 25 to resist the pressure in the pipe 1, thereby reducing the pressure directly exerted on the sealing ring 22 and ensuring the sealing effect.

[0050] Optionally, the support and blocking assembly 3 includes a circular sleeve 31 slidably mounted on the guide column 23, an extended circular sleeve 32 connected to the tail end of the circular sleeve 31, and the pushing handle 24 extends outward from the extended circular sleeve 32, a plurality of sunken grooves 33 circumferentially provided on the main blocking disk 21, a plurality of movable plates 34 slidably mounted in the plurality of sunken grooves 33, a plurality of convex edges 35 circumferentially mounted on the circumferential side of the circular sleeve 31, a plurality of force transmission rods 36 each having one end rotatably mounted on both sides of the plurality of convex edges 35 and the other end rotatably connected to both sides of the plurality of movable plates 34, and a blocking assembly 37 connected to the plurality of movable plates 34;

[0051] The blocking assembly 37 is attached to the back of the main blocking disk 21. After the front blocking mechanism 2 is installed, the extension sleeve 32 is pushed forward, the sleeve 31 is pushed up and down on the guide column 23, and the several force transmission rods 36 are adaptively rotated, thereby pushing the several movable plates 34 along the corresponding sunken grooves 33 until the blocking assembly 37 is tightly pressed against the inner wall of the pipeline 1, ensuring that the blocking assembly 37 can be smoothly expanded to achieve re-blocking.

[0052] Optionally, the blocking assembly 37 includes a plurality of fan-shaped connecting plates 371 respectively installed in front of the plurality of movable plates 34, a plurality of first curved base plates 372 respectively installed on the plurality of fan-shaped connecting plates 371, a plurality of first sealing plates 373 respectively installed on the plurality of first curved base plates 372, a plurality of opening grooves 374 respectively installed on the sides of the plurality of first curved base plates 372, a plurality of second curved base plates 375 respectively slidably installed in the plurality of opening grooves 374, a plurality of second sealing plates 376 respectively installed on the plurality of second curved base plates 375, a plurality of springs 377 respectively arranged in the plurality of opening grooves 374 and respectively connected to one end of the plurality of second curved base plates 375 located in the plurality of opening grooves 374, and a plurality of stop plates 378 respectively installed on the plurality of first curved base plates 372.

[0053] The other ends of the plurality of second curved substrates 375 respectively abut against the plurality of stoppers 378 ;

[0054] The first curved substrates 372 and the first sealing sheets 373 are attached to the back surface of the main blocking plate 21;

[0055] The first sealing pieces 373 are flush with the second sealing pieces 376, and the fan-shaped connecting plates 371 are pushed by the movable plates 34 to spread the first curved base plates 372. As the movable plates 34 continue to move, the first sealing pieces 373 are finally pressed against the inner wall of the pipe 1. During the process of the first curved base plates 372 expanding outward, the diameters gradually increase, and the distance between each two adjacent first curved base plates 372 is gradually increased. The springs 377 respectively push the second curved base plates 375 along the corresponding opening grooves 374. The spring push makes the second curved substrates 375 always maintain the state of abutting against the stop plates 378 until the second sealing plates 376 are also pressed against the inner wall of the pipe 1 at the same time as the first sealing plates 373, so that the second sealing plates 376 and the first sealing plates 373 jointly form a circular abutment with the inner wall of the pipe 1, and then form a blockage at the junction of the sealing ring 22 and the pipe 1 again after the main blocking disk 21 and the sealing ring 22, effectively enhancing the sealing performance, preventing the existence of gaps between the sealing ring 22 and the inner wall of the pipe 1 or insufficient sealing force, and ensuring the sealing effect.

[0056] Optionally, the tightening assembly 4 includes an upper clamping plate 41 and a lower clamping plate 42 symmetrically clamped on the pipe 1, two first bolts 43 screwed on the upper clamping plate 41 and the lower clamping plate 42, a vertical plate 44 integrally connected to the side of the upper clamping plate 41, a rectangular sleeve 45 mounted on the vertical plate 44, a right-angle pull rod 46 with one end slidingly inserted into the rectangular sleeve 45, and the other end of the right-angle pull rod 46 is connected to the extension circular sleeve 32, a handle 47 mounted on the right-angle pull rod 46, and two groups of second bolts 48 screwed on the rectangular sleeve 45 in a mirror-image manner;

[0057] The two groups of several second bolts 48 are in contact with the right-angle pull rod 46. Before installing the front blocking mechanism 2, the upper clamping plate 41 and the lower clamping plate 42 are first clamped on the pipe 1, and the two first bolts 43 are tightened to clamp the upper clamping plate 41 and the lower clamping plate 42 on the pipe 1. When installing the front blocking mechanism 2, the right-angle pull rod 46 is inserted into the square sleeve 45. After completing the re-sealing of the intersection of the sealing ring 22 and the pipe 1, the two groups of several second bolts 48 are tightened to support the right-angle pull rod 46 in the square sleeve 45 and fix it in the current position, thereby extending The circular sleeve 32 is firmly tightened to ensure that the second sealing sheets 376 and the first sealing sheets 373 are kept in tight contact with the inner wall of the pipe 1 to prevent the circular sleeve 32 and the circular sleeve 31 from being extended and retreated after loosening the hand, causing the second sealing sheets 376 and the first sealing sheets 373 to be separated from the inner wall of the pipe 1. At the same time, the front blocking mechanism 2 and the supporting sealing component 3 are fixed as a whole to ensure their pressure resistance and sealing stability, and effectively prevent the front blocking mechanism 2 and the supporting sealing component 3 from being separated from the pipe 1 under the action of the internal pressure of the pipe 1, thereby causing the sealing to fail.

[0058] Optionally, a high-efficiency pipeline sealing plug further includes a clamp 5 provided on the pipeline 1;

[0059] The position of the clamp 5 corresponds to the sealing ring 22 and the sealing assembly 37. Before installing the front blocking mechanism 2, the clamp 5 is put on the pipe 1 according to the preset sealing position and tightened, so that the clamp 5 holds the pipe 1 tightly, thereby providing external protection for the pipe 1 at the sealing point to prevent the pipe 1 from being deformed by force when the multiple second sealing sheets 376 and the multiple first sealing sheets 373 are pressed against the inner wall of the pipe 1. After the multiple second sealing sheets 376 and the multiple first sealing sheets 373 are pressed against the inner wall of the pipe 1, the clamp 5 is further strengthened to hold the pipe 1 tightly, thereby working together with the multiple second sealing sheets 376 and the multiple first sealing sheets 373 inside to form a pair of internal and external matching relative forces, so that the multiple second sealing sheets 376, the multiple first sealing sheets 373 and the sealing ring 22 can fit more closely with the inner wall of the pipe 1, thereby further strengthening the sealing and ensuring the sealing effect.

[0060] Optionally, gaskets 6 are fitted on the inner sides of the upper and lower splints 41 and 42 , and the soft gaskets 6 prevent the hard upper and lower splints 41 and 42 from directly contacting the pipe 1 to prevent damage to the pipe 1 .

[0061] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
