Description

Technical Field

[0001] The present invention relates to the technical field of pipeline leak stoppers, and in particular to a heat pipeline pressure leak stopper. Background Art

[0002] With the rapid development of a large number of residential areas, things around the residential areas have been created, such as heat transportation. The main function of the heat transportation pipeline is to transport heat to the location of the heat users. However, due to the diversity of the types of heat users, the requirements for heat media are also different. When selecting, the usage characteristics and requirements of the heat users and the type of heat source should be comprehensively considered. Commonly used heat media are steam and water, because the environments in which steam and water are located in the heating system are different.

[0003] According to the publication number "CN108458201B", a pipeline pressure rapid leak plugging device uses two parallel leak-blocking rope holes at the bottom of the leak-blocking block for the passage of wire ropes. A rectangular countersunk hole is opened on the upper surface of the leak-blocking block and a high-elastic rubber pad is embedded in it, which plays a role in pressure sealing the pipeline leakage point.

[0004] Although the above-mentioned existing technologies have solved the problem of plugging leaks in pipelines without stopping production, using only plugging blocks and rubber pads to plug leaks in high-pressure pipelines will be affected by the impact of high-pressure gas or liquid, resulting in poor sealing effect.

[0007] Preferably, the vibrating component also includes a limit block, a protrusion, and a cross plate. The limit block is fixedly connected to the inner wall of the upper end of the circular groove, the protrusion is fixedly connected to one side of the tray, and the two cross plates are respectively fixedly connected to both sides of the hinge block. A second spring is fixedly connected between one end of the cross plate and the disc.

[0008] Preferably, two vertically arranged installation boxes are fixedly connected to the inner wall of the steel pipe, and the two installation boxes are respectively arranged on one side of the driving box. A partition is fixedly connected inside the installation box, and the partition divides the installation box into two chambers arranged up and down. A movable plate is slidably connected inside the installation box, and a limiting groove for the sliding of the partition is provided on the movable plate.

[0009] Preferably, a piston plate is fixedly connected to one side of the lower end of the movable plate, and the end of the piston plate away from the movable plate is slidably connected in the chamber located at the lower side, and a first spring is fixedly connected between the piston plate and the inner wall of the chamber located at the lower side.

[0013] Preferably, one end of the protrusion away from the tray is slidably connected to the inner wall of the circular groove, and the protrusion is located directly below the limiting block.

[0014] Preferably, a circular hole for the conical cork to slide is opened on the annular disk, and the circular hole is arranged between the two discharge ports.

[0015] Preferably, a through hole is provided on the upper wall of the tray, and an air vent is provided on the upper end of the drive box.

[0016] Compared with the prior art, the present invention has the following beneficial effects: Polish the area around the leaking point in the pipeline clean, use a hard conical wooden plug to plug the leak in advance, put the steel pipe through the hard conical wooden plug and weld it around the leaking point, so that one end of the steel pipe is aligned with the outer surface of the pipeline, fill the inside of the steel pipe with sealing structural adhesive, and use the upper cover to connect to the steel pipe with threads to achieve a triple leak-plugging effect on the pipeline. This leak plugging technology is not affected by factors such as environment, position, direction, temperature, etc., and can be used without stopping the machine and quickly plugging leaks.

[0017] The two movable plates can respectively clamp the steel nail under the push of the first spring. Since the conical wooden plug is inserted into the leak in the pipe, a preliminary fixation has been formed, and the steel pipe uses the two movable plates to clamp the steel nail, which also directly forms a preliminary fixation effect on the steel pipe, avoiding the end of the steel pipe from shifting before being welded to the outer surface of the pipe. The mutual fixation of the steel nail and the steel pipe also makes it convenient for one staff member to weld between the end of the steel nail and the inner wall of the steel pipe, and also facilitates the welding between the end of the steel pipe and the outer surface of the pipe, and can complete the pipeline plugging work alone.

[0018] Place the muzzle end of the sealant gun in the discharge port of any annular disk, and inject sealant into the pipe through the sealant gun. At this time, the sealing structural glue will seal and seal the joint between the steel pipe and the pipe, and will also seal and seal the conical wooden plug and the pipe leakage, thereby achieving a multi-layer sealing effect on the leakage.

[0019] When the gravity ball slides in the V-shaped tube, it will continuously collide with the trapezoidal block, causing the trapezoidal block and the inside of the V-shaped tube to be impacted and vibrate. At this time, the sealant is continuously injected into the steel tube, and the vibration generated will spread to the structural adhesive, vibrating the structural adhesive, thereby removing the bubbles generated by the injection of the structural adhesive into the steel tube and avoiding the problem of poor sealing of the structural adhesive. Since the gravity ball in the V-shaped tube rolls from top to bottom, it can have the effect of vibrating the structural adhesive from top to bottom in the steel tube to remove bubbles and compact it, thereby increasing the adhesion and sealing effect of the structural adhesive.

[0020] Lay the sealing gasket flat on the annular disk, and seal the discharge port and the circular hole on the annular disk. At this time, the annular disk and the sealing gasket can achieve a multi-layer sealing effect on the structural adhesive in the steel pipe. Then use the upper cover to rotate on the steel pipe for threaded connection, thereby achieving an additional layer of sealing effect on the structural adhesive, and also playing a multi-layer sealing role on the leakage points on the pipeline.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figures 1-16 When the cap 3 is screwed on the outer wall of the pipe 2, the cap 3 is screwed on the inner wall of the pipe 2, and the cap 3 is screwed on the outer wall of the pipe 2.

[0025] Reference Figure 4-Figure 7, two drive boxes 16 are fixedly connected on the inner wall of the steel pipe 2, and a circular groove is opened in the drive box 16. The circular groove is in the drive box 16, and the second air bag 18, the disc 19, the tray 20, etc. all slide in the circular groove. The bottom wall of the circular groove is fixedly connected with a second air bag 18 set in a cylindrical shape. Only the bottom of the second air bag 18 is fixedly connected to the bottom wall of the circular groove, and the side wall is not fixed to the circular groove. The second air bag 18 is retractable and can be automatically folded when contracted under the limit of the inner wall of the circular groove. The upper end of the second air bag 18 is fixedly connected with The disc 19 is fixedly connected to a fixed block 27, and the fixed block 27 is rotatably connected to a horizontally arranged support rod 24. A vibrating component is installed on the disc 19, and the vibrating component includes a tray 20, a hinge block 23, a gravity ball 22, and a V-shaped tube 6. The two ends of the hinge block 23 are respectively fixedly connected to the support rod 24. The hinge block 23 can swing with the support rod 24 as a fulcrum. The tray 20 is fixedly connected to the hinge block 23. Both ends of the V-shaped tube 6 are connected to the drive box 16. The two opposite inner walls of the V-shaped tube 6 are fixed. There are multiple trapezoidal blocks 33 connected. The trapezoidal blocks 33 on the same side wall are arranged at equal distances, and the trapezoidal blocks 33 on two different side walls are arranged in a staggered manner. Therefore, the gravity ball 22 will be limited by the trapezoidal blocks 33 during the sliding process, so that the gravity ball 22 continuously hits the inner wall of the V-shaped tube 6. After the collision, the trapezoidal blocks 33 and the V-shaped tube 6 vibrate, and the vibration is transmitted to the structural glue inside the steel pipe 2 for defoaming. The gravity ball 22 is set on the tray 20. The gravity ball 22 is a sphere with a smooth outer surface. At the same time, the gravity ball 22 will be limited by the trapezoidal block 33 and its sliding speed in the V-shaped tube 6 will be slowed down, which will cause the tray 20 to move down and reset first, and then the gravity ball 22 can be discharged through the lower end of the V-shaped tube 6 and slide onto the through hole on the tray 20, which can seal the through hole on the tray 20 again. The gas inside the second airbag 18 increases, and the driving force of the air pressure is less than the gravity of the gravity ball 22. Therefore, when the second airbag 18 expands, the internal gas cannot push the gravity ball 22 to move and separate from the tray 20.

[0026] Reference Figure 7-12The vibrating component also includes a limit block 17, a protrusion 21, and a cross plate 25. The limit block 17 is fixedly connected to the inner wall of the upper end of the circular groove. One side of the limit block 17 is the opening side of the upper end of the V-shaped tube 6. The protrusion 21 is fixedly connected to one side of the tray 20. The two cross plates 25 are respectively fixedly connected to both sides of the hinge block 23. A second spring 26 is fixedly connected between one end of the cross plate 25 and the disc 19. The end of the protrusion 21 away from the tray 20 is slidably connected to the inner wall of the circular groove. The protrusion 21 is located directly below the limit block 17. When the tray 20 moves upward, the protrusion 21 is limited by the limit block 17. , it will first tilt to the right. When it tilts to a certain angle, the protrusion 21 passes the limit block 17, and the tray 20 will swing under the tension of the second spring 26. When the tray 20 swings to tilt to the left, the gravity ball 22 will slide from the opening at the upper end of the V-shaped tube 6 into the V-shaped tube 6, and the tray 20 will slowly return to a horizontal state. A through hole is provided on the upper wall of the tray 20, and the gas in the second airbag 18 will be discharged into the circular groove through the through hole along with the hose and the tray 20. The gas in the circular groove will be discharged into the air outside the drive box 16 through the vent. The drive box 16 has an vent at the upper end.

[0027] Reference Figure 3-Figure 4, a conical wooden plug 4 is inserted into the pipe 1, and the conical wooden plug 4 is used to seal the leaks on the pipe 1. A steel nail 5 is inserted into the conical wooden plug 4. A sealing gasket 28 is installed on the upper end of the steel pipe 2. Two vertically arranged installation boxes 7 are fixedly connected to the inner wall of the steel pipe 2. The two installation boxes 7 are respectively arranged on one side of the drive box 16. A partition 14 is fixedly connected to the installation box 7. The partition 14 divides the installation box 7 into two chambers arranged up and down. A movable plate 9 is slidably connected to the installation box 7. A piston plate 15 is fixedly connected to the lower end of the movable plate 9. The piston plate The end of the piston plate 15 away from the movable plate 9 is slidably connected to the chamber located at the lower side. A first spring 11 is fixedly connected between the piston plate 15 and the inner wall of the lower chamber. The outer surface of the piston plate 15 is provided with a sealing structure to ensure that it can slide in a sealed manner with the inner wall of the lower chamber, thereby pushing the gas located in the lower chamber. A first airbag 13 is fixedly connected to the upper chamber. The first airbag 13 is connected to the lower chamber. The upper end of the first airbag 13 is fixedly connected to a sleeve 32. The lower end of the sleeve 32 is provided with an exhaust port 31. The sleeve 32 passes through the exhaust port 31. 1 is connected to the first airbag 13. When the movable plate 9 moves in the upper chamber, it can move to fit the side wall of the first airbag 13, so that the first airbag 13 is limited by three sides of the chamber and one side of the movable plate 9. When the gas in the lower chamber enters the first airbag 13, the first airbag 13 expands and stretches. At the same time, when the vertical rod 8 squeezes the first airbag 13, the first airbag 13 will not bend due to the limitation of the chamber and the movable plate 9, but will be vertically compressed, so as to completely discharge the gas in the first airbag 13. That is, after the first airbag 13 expands, the internal gas will be squeezed by the first airbag 13 and produce a tendency to push the gas back to the lower chamber and squeeze the piston plate 15 and the movable plate 9 to reset and move. Therefore, the push of the gas and the thrust of the first spring 11 on the piston plate 15 and the movable plate 9 can make the two movable plates 9 form a tighter clamping force on the steel nail 5, thereby achieving the fixing effect of the steel pipe 2. A limiting groove for the sliding of the partition 14 is provided on the movable plate 9. When the movable plate 9 slides in the installation box 7, the partition 14 will slide in the limiting groove.

[0028] Reference Figure 5 as well as Figure 13-16, a vertical rod 8 is slidably connected in the sleeve 32, and the vertical rod 8 is hollow. The outer surface of the vertical rod 8 and the inner wall of the sleeve 32 are smooth. An air inlet 30 is provided on the vertical rod 8, and a third spring 29 is fixedly connected between the lower end of the vertical rod 8 and the bottom wall of the sleeve 32. The third spring 29 has an upward pushing force on the vertical rod 8. A connecting pipe 12 is fixedly connected between the vertical rod 8 and the second airbag 18. An annular disk 10 is fixedly connected between the two vertical rods 8. The outer ring diameter of the annular disk 10 is slightly smaller than the inner diameter of the steel pipe 2. Therefore, a circular hole for sliding the conical wooden plug 4 is provided on the annular disk 10. The circular hole is provided between the two feeding ports so that the upper surface of the annular disk 10, the upper surface of the conical wooden plug 4 and the steel pipe 2 The upper surfaces are on the same horizontal line, which is beneficial to the sealing effect of the sealing gasket 28 on the components and sealant in the steel pipe 2. Two discharge ports are provided on the annular disk 10. Since the glue gun discharge hose is generally also set in a conical shape, the glue gun discharge hose is placed in the discharge port to inject glue into the steel pipe 2, which is also convenient for squeezing the annular disk 10 downward. The lower end faces of the two movable plates 9 are inclined to facilitate the steel nail 5 to slide between the two movable plates 9. The lower end of the steel pipe 2 is provided with an arc groove for fitting with the outer surface of the pipeline 1, so that the steel pipe 2 can better fit the outer surface of the pipeline 1, and can reduce the gap at the connection between the steel pipe 2 and the pipeline 1, so as to facilitate the sealing of the connection between the steel pipe 2 and the pipeline 1 by the sealant.

[0029] In the present invention, when in use, first select a hard conical wooden plug 4 and a steel pipe 2 of matching diameter according to the caliber of the leak point of the pipe 1, polish the area around the leak point of the pipe 1, and use the hard conical wooden plug 4 to plug the leak point in advance. Then, drill a hole horizontally at the hard conical wooden plug 4 40-50mm away from the main pipe to install a steel nail 5 smaller than the inner diameter of the steel pipe 2. Then, the steel pipe 2 is put through the hard conical wooden plug 4 and welded around the leak point so that one end of the steel pipe 2 coincides with the outer surface of the pipe 1. Then, the steel nail 5 on the hard conical wooden plug 4 is welded to the inner wall of the steel pipe 2 for fixation. Then, the conical wooden plug 4 is sawed off at the height of the steel pipe 2. The inside of the steel pipe 2 is filled with sealing structural glue. Then, the sealing gasket 28 is placed on the upper end of the steel pipe 2 and the upper cover 3 is threadedly connected to the steel pipe 2 to achieve a triple leak-proof effect on the pipe 1. The leak stopper uses metal materials and sealants, so it is not affected by factors such as environment, position, direction, and temperature.

[0030] When the steel nail 5 is installed on the conical wooden plug 4, the steel pipe 2 is sleeved with the position between the two movable plates 9 at one end of the steel nail 5. As the steel pipe 2 moves downward, the two movable plates 9 move away from each other under the limit of the steel nail 5. When the piston plate 15 moves in the chamber located at the lower side in the installation box 7 as the movable plate 9 moves, it can squeeze the gas located in the lower chamber and the first spring 11. At this time, the two movable plates 9 can achieve a clamping effect on the steel nail 5 under the push of the first spring 11. Since the conical wooden plug 4 is inserted into the hole in the steel pipe 2, it has been fixed, and the steel pipe 2 uses the two movable plates 9 to clamp the steel nail 5, which also directly forms a fixing effect on the steel pipe 2, preventing the end of the steel pipe 2 from deviating after being fitted with the outer surface of the pipeline 1. The mutual fixation of the steel nail 5 and the steel pipe 2 also facilitates the welding between the end of the steel nail 5 and the inner wall of the steel pipe 2, and also facilitates the welding between the end of the steel pipe 2 and the outer surface of the pipeline 1. One person can complete the leak-proof work of the pipeline 1 alone.

[0031] At the same time, when the piston plate 15 moves with the moving plate 9 to squeeze the gas in the lower chamber, the gas will enter the first airbag 13. As the gas in the first airbag 13 increases, it expands between the moving plate 9 and the inside of the chamber and pushes the sleeve 32 to move upward. Since the vertical rod 8 slides in the sleeve 32 through the third spring 29, the sleeve 32 pushes the vertical rod 8 to move upward through the third spring 29. Figure 3 As shown, the annular disk 10 moves up to above the steel pipe 2 along with the vertical rod 8. As the annular disk 10 moves up, the annular disk 10 is separated from the steel pipe 2, which also makes it easier for workers to use a welding gun to weld the inner wall of the steel pipe 2 and the end of the steel nail 5.

[0032] When the steel pipe 2 and the conical wooden plug 4 are fixed, when it is necessary to inject sealing structural glue into the steel pipe 2, the staff holds the sealing glue gun, places the end of the sealing glue gun muzzle in the discharge port on any annular disk 10, and injects glue into the steel pipe 2 through the sealing glue gun. At this time, the sealing structural glue will seal and close the joints between the steel pipe 2 and the pipeline 1, and will also seal and close the leaks between the conical wooden plug 4 and the pipeline 1, thereby achieving a multi-layer sealing effect on the leaks by utilizing the combination of the steel pipe 2, the conical wooden plug 4 and the sealing structural glue.

[0033] During the glue injection process, the glue gun is pressed downward. Since the first airbag 13 is filled with gas, the glue gun will push the annular disk 10 downward. As the annular disk 10 moves downward in the sleeve 32, the vertical rod 8 will squeeze the third spring 29. At this time, the first airbag 13 will not be deformed. When the third spring 29 is squeezed to the extreme and cannot be compressed anymore, the air inlet 30 on the vertical rod 8 coincides with the exhaust port 31 on the sleeve 32. At this time, part of the gas in the first airbag 13 enters the vertical rod 8 through the exhaust port 31 and the air inlet 30, and enters the second airbag 18 through the vertical rod 8 and the connecting pipe 12. Since the second airbag 18 is connected to the tray 20 through a hose, and the gravity ball 22 is on the through hole at the upper end of the tray 20, the gravity ball 22 will close the through hole. At this time, the gas inside the second airbag 18 cannot be discharged. It is limited by the internal position of the circular groove. After the internal gas increases and expands, it can push the disc 19 to move upward in the circular groove. After the tray 20 and the gravity ball 22 are pushed up to the upper end of the circular groove by the second airbag 18, the protrusion 21 on the tray 20 is limited by the limit block 17, so that the tray 20 will be turned clockwise through the hinge block 23 and the support rod 24. Angle, and stretch the second spring 26. At this time, the gravity ball 22 contacts the inner wall of the circular groove as the tray 20 tilts, and will not detach from the through hole on the tray 20 until the tray 20 continues to move upward with the push of the second airbag 18. After the protrusion 21 passes the limit block 17, the disc 20 and the hinge block 23 will rotate counterclockwise to tilt and swing to the left under the rapid tension of the second spring 26, and then slowly become horizontal. When the tray 20 swings to tilt to the left, the gravity ball 22 will slide into the upper end of the V-shaped tube 6 under its own gravity, and the gravity ball 22 will be in the V-shaped tube 6. When sliding inside, it will continuously collide with the trapezoidal block 33, causing the trapezoidal block 33 and the V-shaped tube 6 to be impacted and vibrate. At this time, the glue is continuously injected into the steel pipe 2, and the vibration generated will spread to the structural glue, vibrating the structural glue, thereby removing the bubbles generated inside the steel pipe 2 when the structural glue is injected, resulting in poor sealing of the structural glue. Since the gravity ball 22 in the V-shaped tube 6 rolls from top to bottom, it can have a vibrating and de-foaming effect on the structural glue from top to bottom in the steel pipe 2, thereby increasing the adhesion and sealing effect of the structural glue.

[0034] As the staff no longer squeezes the annular disk 10, the annular disk 10 and the vertical rod 8 move upward and reset under the elastic force of the third spring 29. As the vertical rod 8 moves upward, the air inlet 30 and the exhaust port 31 are misaligned, as shown in the attached figure. Figure 5As shown, the inner wall of the sleeve 32 will close the air inlet 30, and the outer wall of the vertical rod 8 will close the exhaust port 31. As the gravity ball 22 enters the V-shaped tube 6 and no longer seals the through hole on the tray 20, the gas in the second airbag 18 is discharged from the through hole through the hose and the tray 20, and the discharged gas is discharged to the outside of the drive box 16 through the air vent. After the gas in the second airbag 18 is continuously discharged, the tray 20, the hinge block 23 and the disc 19 move downward under their own gravity and compress the second airbag 18, which can speed up the gas discharge speed of the second airbag 18. After the gas in the second airbag 18 is discharged, it resets. At this time, the tray 20 is on the lower side of the lower end of the V-shaped tube 6. Since the gravity ball 22 will be hindered by the trapezoidal block 33 in the V-shaped tube 6, the gravity ball 22 slides down slowly, much lower than the tray 20. The speed of downward reset, so the tray 20 is reset first, and the gravity ball 22 will slide down the V-shaped tube 6 to the tray 20 under its own gravity, and close the through hole on the tray 20 here, so that the staff can squeeze the annular disk 10 here. The principle after the annular disk 10 is squeezed is as shown above. As the staff uses the glue gun to continuously inject glue into the steel pipe 2, the staff squeezes the annular disk 10 in order and intermittently. Each time the annular disk 10 is squeezed, the gas in the first airbag 13 will re-enter the second airbag 18. The expansion of the second airbag 18 will push the gravity ball 22 to move up and slide into the V-shaped tube 6, hitting the inner wall of the V-shaped tube 6 and the trapezoidal block 33, generating vibration and transmitting it to the structural glue in the steel pipe 2, breaking and compacting the bubbles in the structural glue.

[0035] After the gas in the first airbag 13 is exhausted, the annular disc 10 moves down to its original position along with the upper end of the first airbag 13 through the vertical rod 8. At this time, the annular disc 10 is at the upper end of the installation box 7, and the upper surface of the annular disc 10 is just flush with the top of the steel pipe 2. At this time, the staff uses a glue gun to fill the steel pipe 2 through the discharge port on the annular disc 10. The annular disc 10 can have a mobile squeezing effect on the glue, so that the structural glue in the steel pipe 2 has a compacting effect. At the same time, the upper surface of the annular disc 10 is on the same horizontal line as the steel pipe 2 and the top of the conical wooden plug 4, so the excess structural glue will pass through Overflow from the discharge port also makes it convenient for the staff to scrape off the excess structural adhesive directly from the upper end face of the steel pipe 2, and then spread the sealing gasket 28 flat on the annular disk 10, and seal the discharge port and the circular hole on the annular disk 10. At this time, the annular disk 10 and the sealing gasket 28 can achieve a multi-layer sealing effect of the structural adhesive in the steel pipe 2, and then the upper cover 3 is rotated on the steel pipe 2 for threaded connection, and the upper cover 3 is used to protect the structural adhesive and components in the steel pipe 2, thereby achieving an extra layer of sealing effect for the structural adhesive, and also playing a multi-layer sealing role for the leakage points on the pipeline 1.
