Description

Technical Field

[0001] The utility model relates to the technical field of pipeline leak plugging, in particular to a pressure - retaining leak plugging device for heating pipelines. Background Technique

[0002] During the use of heating pipelines, due to their own aging or external damage, the pipe wall is likely to rupture and leak. In order not to affect the use of the other end of the pipeline, it is often necessary to repair the pipeline by pressure - retaining leak plugging.

[0003] After retrieval, a patent with the Chinese patent publication number CN217422619U discloses a pressure - retaining leak plugging device for heating pipelines, which mainly seals the leakage port through simple structures such as a sealing plate, a ferrule, a screw sleeve, a bolt, and a locking plate.

[0004] Comparing with the prior art in the related field, when the existing device uses a gasket to press - fit and seal the leakage port, it uses the gasket in cooperation with an external pressing structure to press - fit and seal the leakage port. However, the existing standard sealing structure has a low adaptability to pipelines. Only relying on the self - deformation of the gasket cannot perfectly fit the outer end face of the pipeline, resulting in a low sealing effect. Content of the Utility Model

[0005] The purpose of the utility model is to provide a pressure - retaining leak plugging device for heating pipelines to solve the above problems.

[0006] The utility model realizes the above - mentioned purpose through the following technical solutions:

[0007] A pressure - retaining leak plugging device for heating pipelines includes a support base and a pipeline. Fixed units are arranged at both ends of the support base. A pressing unit and a lining plate are arranged on the support base. The support base is installed on the pipeline through the fixed units. A gasket is connected to the lining plate. The gasket is placed on the pipeline. By using the fixed units to install the support base on the pipeline, moving the support base and the gasket to the leakage location on the pipeline, the pressing unit presses the gasket tightly on the pipeline through the lining plate, thereby plugging the leakage location on the pipeline.

[0008] The pressing unit includes an intake valve and a placement groove. Adjusting components and the intake valve are equidistantly arranged on the support base. The adjusting components correspond to the intake valve. A placement groove is provided inside the support base. A movable seat is connected to the part of the adjusting component located inside the placement groove. A connecting seat is rotatably connected to the movable seat. The connecting seat is connected to a pressing plate. The pressing plate is slidably connected inside the placement groove. The pressing plate is located above the lining plate. A first installation groove is provided on the lower surface of the pressing plate. A first airbag is installed inside the first installation groove. The first airbag is connected to the intake valve. The adjusting component drives the pressing plate to move through the movable seat and the connecting seat. The lining plate and the gasket are multi-point pressed through the pressing plate. Through the multi-point pressing, the reverse impact force received by the lining plate and the gasket can be better dispersed, reducing the reverse impact force formed by the internal pressure and ensuring the sealing effect of the gasket. At the same time, since the movable seat and the connecting seat are movably connected, when the pressing plate presses the gasket through the lining plate, the pressing plate will tilt to a certain extent according to the curvature of the pipe surface. The pressing plate can apply pressure to the gasket according to the curvature of the pipe surface. Then, the first airbag is inflated through the intake valve, and the gap between the pressing plate and the lining plate is filled through the first airbag, enabling the pressing plate to tightly press the lining plate comprehensively and effectively, so that the gasket can better fit on the pipe, effectively improving the sealing performance between the gasket and the pipe and enhancing the sealing effect.

[0009] Further, the adjusting component on the support base includes a bolt seat. The bolt seats are equidistantly arranged on the support base. A first bolt is helically installed on the bolt seat. The part of the first bolt located inside the placement groove is rotatably connected to the movable seat. By adjusting the length of the connection between the first bolt and the bolt seat, the first bolt drives the movable seat to move.

[0010] Further, anti-slip blocks are provided on the side surface of the lining plate. The anti-slip blocks are connected to the gasket, improving the connection stability between the lining plate and the gasket through the anti-slip blocks.

[0011] Further, a connection valve is provided on the side surface of the support base. A second installation groove is provided on the inner side surface of the support base. A second airbag is installed inside the second installation groove. The second airbag is communicated with the connection valve. The second airbag is inflated through the connection valve, and the gap between the support base and the pipe is filled through the second airbag, improving the sealing performance between the support base and the pipe.

[0012] Further, a glue injection valve is provided on the support base. A glue injection cavity is formed between the second airbag and the side surfaces of the lining plate and the gasket. The glue injection cavity is communicated with the glue injection valve. Sealing glue is injected into the glue injection cavity through the glue injection valve, improving the sealing performance between the lining plate, the gasket and the second airbag.

[0013] Further, the fixing unit on the support base includes a traction belt and a second bolt. The traction belt is installed on both sides of the support base. A locking plate is installed at the end of the traction belt. The second bolt is threadedly connected to the locking plate. The support base is fixed on the pipe through the second bolt, the locking plate and the traction belt.

[0014] Further, positioning arrows are provided on both sides of the support base, and the center position of the support base corresponds to the leakage opening on the pipeline through the positioning arrows.

[0015] The beneficial effects compared with the prior art are as follows:

[0016] 1. By using the first bolts, bolt seats, movable seats, connecting seats and pressing plates to press the lining plate and the gasket at multiple points, the reverse impact force received by the lining plate and the gasket can be better dispersed, reducing the reverse impact force formed by the internal pressure, ensuring the sealing effect of the gasket and the safety during use. At the same time, since the movable seat and the connecting seat are movably connected, the pressing plate can generate a certain inclination, and the pressing plate can apply pressure to the gasket according to the curvature of the pipeline surface. Then, the first airbag fills the gap between the pressing plate and the lining plate, enabling the pressing plate to press the lining plate comprehensively and effectively, so that the gasket can better fit on the pipeline, effectively improving the sealing performance between the gasket and the pipeline and enhancing the sealing effect.

[0017] 2. The gap between the support base and the pipeline is filled with the second airbag, and then sealant is injected into the sealant injection cavity through the sealant injection valve, thereby improving the sealing performance between the lining plate, the gasket, the second airbag and the pipeline and ensuring the sealing effect.

[0029] As Figures 1-8 shown, a pressure - retaining leak - plugging device for a heating pipeline includes a support seat 1 and a pipeline 2. Fixed units are arranged at both ends of the support seat 1. A pressing unit 3 and a liner 4 are arranged on the support seat 1. The support seat 1 is installed on the pipeline 2 through the fixed units. A sealing gasket 5 is connected to the liner 4. The sealing gasket 5 is placed on the pipeline 2. As Figure 4 shown, the sealing gasket 5 is placed on the pipeline 2. As Figures 1-3 shown, the support seat 1 is installed on the pipeline 2 through the fixed units, and the liner 4 is pressed against the sealing gasket 5. The support seat 1 and the sealing gasket 5 are moved to the leakage point on the pipeline 2. The pressing unit 3 presses the sealing gasket 5 tightly against the pipeline 2 through the liner 4, thereby plugging the leakage point on the pipeline 2;

[0030] The pressing unit 3 includes an air inlet valve 38 and a placement groove 39. Adjusting components and the air inlet valve 38 are equidistantly arranged on the support base 1. The adjusting components correspond to the air inlet valve 38. A placement groove 39 is arranged inside the support base 1. A movable seat 33 is connected to the part of the adjusting component located inside the placement groove 39. A connecting seat 34 is rotatably connected to the movable seat 33. The connecting seat 34 is connected to a pressing plate 35. The pressing plate 35 is slidably connected inside the placement groove 39. The pressing plate 35 is located above the lining plate 4. A first installation groove 36 is arranged on the lower surface of the pressing plate 35. A first airbag 37 is installed inside the first installation groove 36. The first airbag 37 is connected to the air inlet valve 38. As Figures 1-7 shown, when the support base 1 and the gasket 5 move to the leakage point on the pipeline 2, the support base 1 presses the gasket 5 on the pipeline 2 through the lining plate 4 to limit the gasket 5. The adjusting component drives the pressing plate 35 to move through the movable seat 33 and the connecting seat 34, and the lining plate 4 and the gasket 5 are multi-point pressed through the pressing plate 35. Through multi-point pressing, the reverse impact force received by the lining plate 4 and the gasket 5 can be better dispersed, reducing the damage to the gasket 5 caused by the reverse impact force formed by the internal pressure and ensuring the sealing effect of the gasket 5. At the same time, since the movable seat 33 and the connecting seat 34 are movably connected, when the pressing plate 35 presses the gasket 5 through the lining plate 4, the pressing plate 35 will tilt to a certain extent according to the curvature of the surface of the pipeline 2. The pressing plate 35 can apply pressure to the gasket 5 according to the curvature of the surface of the pipeline 2. Then, the first airbag 37 is inflated through the air inlet valve 38, and the gap between the pressing plate 35 and the lining plate 4 is filled through the first airbag 37, so that the pressing plate 35 presses the lining plate 4 comprehensively and effectively, so that the gasket 5 can better fit on the pipeline 2, effectively improving the sealing performance between the gasket 5 and the pipeline 2 and improving the sealing effect.

[0031] The adjusting component on the support base 1 includes a bolt seat 32. The bolt seats 32 are equidistantly arranged on the support base 1. A first bolt 31 is spirally installed on the bolt seat 32. The part of the first bolt 31 located inside the placement groove 39 is rotatably connected to the movable seat 33. As Figures 1-5 、 Figure 7 shown, by rotating the first bolt 31, the length of the connection between the first bolt 31 and the bolt seat 32 is adjusted, and the movable seat 33 is driven to move through the first bolt 31, so as to push the pressing plate 35 and make the pressing plate 35 press on the lining plate 4.

[0032] Anti-slip blocks 6 are arranged on the side surface of the lining plate 4. The anti-slip blocks 6 are connected to the gasket 5. As Figure 8 shown, the stability of the connection between the lining plate 4 and the gasket 5 is improved through the anti-slip blocks 6, avoiding the deviation of the sealing position of the gasket 5 caused by the sliding between the lining plate 4 and the gasket 5 when the lining plate 4 presses the gasket 5.

[0033] A connecting valve 9 is provided on the side of the support seat 1, and a second installation groove 7 is provided on the inner side of the support seat 1. A second airbag 8 is installed in the second installation groove 7, and the second airbag 8 is communicated with the connecting valve 9. As Figure 1 , Figure 4 , Figure 7 , Figure 8 shown, after the support seat 1 is fixed to the pipeline 2, the second airbag 8 is inflated through the connecting valve 9, and the gap between the support seat 1 and the pipeline 2 is filled through the second airbag 8, so as to improve the sealing performance between the support seat 1 and the pipeline 2.

[0034] A glue injection valve 10 is provided on the support seat 1. A glue injection cavity 11 is formed between the second airbag 8 and the sides of the lining plate 4 and the gasket 5, and the glue injection cavity 11 is communicated with the glue injection valve 10. As Figure 4 , Figure 6 shown, after the gap between the support seat 1 and the pipeline 2 is filled by the second airbag 8, sealant is injected into the glue injection cavity 11 through the glue injection valve 10, and the gap between the lining plate 4, the gasket 5, the second airbag 8 and the pipeline 2 is filled by the sealant, effectively improving the sealing performance between the lining plate 4, the gasket 5 and the second airbag 8.

[0035] The fixing unit on the support seat 1 includes a traction belt 12 and a second bolt 14. The traction belt 12 is installed on both sides of the support seat 1, and a locking plate 13 is installed at the end of the traction belt 12. The second bolt 14 is threadedly connected to the locking plate 13. As Figure 1 , Figure 2 , Figure 5 , Figure 7 shown, after the support seat 1 is placed on the pipeline 2, the two locking plates 13 are connected by the second bolt 14. The second bolt 14 is rotated, and the distance between the two locking plates 13 becomes smaller through the two locking plates 13, and the two locking plates 13 and the traction belt 12 fix the support seat 1 on the pipeline 2.

[0036] Positioning arrows 15 are provided on both sides of the support seat 1. As Figure 1 , Figure 6 , Figure 7 shown, when plugging the leakage port on the pipeline 2, the leakage port on the pipeline 2 is marked, and the center position of the support seat 1 corresponds to the leakage port on the pipeline 2 through the positioning arrow 15, so as to avoid the plugging position from being skewed and ensure the plugging effect.

[0037] Working principle: When plugging the leakage point on the pipeline 2, first mark the leakage point on the pipeline 2. As Figure 4 shown, place the gasket 5 on the pipeline 2. As Figure 2 , Figure 4 , Figure 7As shown, press the support base 1 onto the gasket 5 through the liner plate 4, and move the support base 1 and the gasket 5 to the leakage point on the pipeline 2. As Figure 8 shown, prevent sliding misalignment between the liner plate 4 and the gasket 5 through the anti-slip block 6;

[0038] As Figure 1 、 Figure 6 、 Figure 7 shown, align the positioning arrow 15 with the mark on the pipeline 2. As Figure 1 、 Figure 2 、 Figure 5 、 Figure 7 shown, connect the two locking plates 13 through the second bolt 14. Rotate the second bolt 14, and the distance between the two locking plates 13 will become smaller through the two locking plates 13. The two locking plates 13 pull the belt 12 to fix the support base 1 on the pipeline 2, thereby pressing the gasket 5 onto the leakage point on the pipeline 2;

[0039] As Figures 1-5 、 Figure 7 shown, rotate the first bolt 31 one by one to adjust the connection length between the first bolt 31 and the bolt seat 32. Drive the movable seat 33 to move through the first bolt 31, and drive the pressing plate 35 to move through the connecting seat 34 by the movable seat 33, and press the liner plate 4 and the gasket 5 at multiple points through the pressing plate 35;

[0040] As Figure 3 、 Figure 4 shown, since the movable seat 33 and the connecting seat 34 are movably connected, when the pressing plate 35 presses the gasket 5 through the liner plate 4, the pressing plate 35 will tilt to a certain extent according to the curvature of the surface of the pipeline 2. The pressing plate 35 can apply pressure to the gasket 5 according to the curvature of the surface of the pipeline 2. Then, inflate the first airbag 37 through the air inlet valve 38, and fill the gap between the pressing plate 35 and the liner plate 4 through the first airbag 37, so that the pressing plate 35 presses the liner plate 4 comprehensively and effectively, so that the gasket 5 can better fit on the pipeline 2;

[0041] As Figure 1 、 Figure 4 、 Figure 7 、 Figure 8 shown, inflate the second airbag 8 through the connecting valve 9, and fill and seal the gap between the support base 1 and the pipeline 2 through the second airbag 8;

[0042] As Figure 4 、 Figure 6As shown, after the second airbag 8 fills the gap between the support seat 1 and the pipeline 2, sealant is injected into the sealant injection cavity 11 through the sealant injection valve 10, and the gap between the lining plate 4, the gasket 5, the second airbag 8 and the pipeline 2 is filled and sealed with the sealant, effectively improving the sealing performance between the gasket 5 and the pipeline 2.
