Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline repair, and more specifically, to a pipeline leak stopper. Background Technology
[0002] After prolonged operation, condensate pipes and water supply pipes may leak due to pipe aging, corrosion, or external factors. When water is shut off for maintenance, it can disrupt the normal water supply to users. Therefore, it is necessary to have a means to quickly deal with the leak without interrupting the water supply.
[0003] CN117537205A discloses a pipe leak repair device, including two hinged clamping blocks. The two clamping blocks have clamping openings for holding the pipe, and these openings form a circle when joined. The free ends of the two clamping blocks are provided with detachable connecting bolts. This invention can improve the efficiency of pipe seepage repair, effectively reduce the risk of unauthorized unit shutdowns in hydropower stations due to seepage, and lower subsequent maintenance costs. Like existing leak-sealing metal rings, this patent uses a ring design to seal the damaged area of the pipe, aiming to maintain normal pipe use without replacement. However, it cannot predict the damaged area and pipe diameter in advance. Therefore, during emergency repairs, there may be a mismatch between the sealing structure and the damaged area, hindering the repair work. Therefore, a pipe leak sealer is proposed to solve the above problems. Utility Model Content
[0004] To overcome the problem of mismatch between the sealing structure and the damaged area of the pipe and the pipe in the existing technology, this utility model provides a pipe plugging device, including a fixed outer ring, an adhesive component fixedly installed on the inner wall of the fixed outer ring, and a flexible patch threaded on the end of the adhesive component away from the fixed outer ring.
[0005] Preferably, there are two fixed outer rings and two flexible patches, and the number of bonding components is six. Three bonding components form a group, and the two ends of each group of bonding components are fixedly connected to the fixed outer ring and the flexible patch, respectively.
[0006] The flexible patch can be evenly applied to the damaged area of the pipe by providing support through three bonding components.
[0007] Preferably, the two fixed outer rings and the two flexible patches are all semi-circular in shape, and the flexible patches are made of flexible plastic sheet.
[0008] Flexible plastic sheets have good plasticity and sealing properties.
[0009] Preferably, the bonding assembly includes a sleeve, which is fixedly connected to a fixed outer ring. A spring seat is fixedly installed inside the sleeve, and a telescopic spring is fixedly installed inside the spring seat. A connecting plate is fixedly installed at the end of the telescopic spring away from the spring seat. A slider is fixedly installed on the outer wall of the connecting plate, and a connecting screw is fixedly installed at the end of the connecting plate away from the telescopic spring. A limit slide rail is fixedly installed on the inner wall of the sleeve, and the slider is slidably connected to the inside of the limit slide rail.
[0010] Preferably, threaded grooves are provided on the opposite sides of the two flexible patches, and the connecting screw is adapted to the threaded grooves.
[0011] The threaded connection method allows for the removal and installation of flexible patches of different sizes to meet the sealing area requirements.
[0012] Preferably, each of the two fixed outer rings is fixedly mounted with a connecting piece at both ends, and each of the four connecting pieces has two threaded holes inside.
[0013] Preferably, each of the four connecting pieces has a connecting bolt threaded inside.
[0014] Preferably, all four connecting bolts are threaded with positioning nuts.
[0015] Preferably, the limiting slide rail is L-shaped.
[0016] It can prevent the connecting plate from derailing and ensure that the movement trajectory of the connecting screw remains stable.
[0017] Beneficial effects:
[0018] The beneficial effects of adopting the technical solution of this utility model are as follows:
[0019] (1) The outer ring and the flexible patch are connected by the bonding component. The flexible patch and the bonding component are detachable. Therefore, multiple flexible patches of different sizes can be carried and the appropriate flexible patch can be selected according to the damaged area of the pipeline on site for adaptive sealing. The maintenance and replacement cost is lower. Compared with the traditional metal ring seal, it has a faster, more efficient and more adaptable sealing effect, and is suitable for temporary sealing and emergency repair operations.
[0020] (2) Both the bonding component and the flexible patch have a certain deformation capacity. The fixed outer ring still adopts a rigid design to ensure the strength of the sealing structure. The two fixed outer rings are connected by connecting bolts. Therefore, the spacing between the fixed outer rings can be changed to adapt to different pipes. The flexible patch is accurately pushed to the pipe damage location by relying on the deformation capacity of the bonding component. This can effectively reduce the impact of gas and liquid pressure in the pipe and thus improve the sealing effect. The sealing effect of the combination of flexible patch and rigid structure is better than that of traditional metal ring sealing. No additional sealing material is required, and the time required for emergency repair is also reduced. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments. The specific embodiments are as follows:
[0029] like Figures 1 to 4 As shown, a pipe sealing device includes a fixed outer ring 1. An adhesive component 2 is fixedly installed on the inner wall of the fixed outer ring 1. A flexible patch 3 is threaded onto the end of the adhesive component 2 away from the fixed outer ring 1. There are two fixed outer rings 1 and two flexible patches 3, and six adhesive components 2 in total. Three adhesive components 2 form a group, and both ends of each group of adhesive components 2 are fixedly connected to the fixed outer ring 1 and the flexible patch 3, respectively. Both the two fixed outer rings 1 and the two flexible patches 3 are semi-circular in shape, and the flexible patch 3 is made of flexible plastic sheet. All components are made of metal, and three bonding components 2 are evenly distributed on the inner wall of each fixed outer ring 1. The flexible patch 3 is connected through the bonding components 2. The flexible patch 3 is a flexible plastic plate that can deform to a certain extent. The position and number of the threaded grooves 30 opened on the flexible patch 3 are not limited, but there are no fewer than three. The appropriate size of the flexible patch 3 is selected according to the actual area of the damaged pipe. The assembly can be completed by connecting the bonding components 2 with the threaded grooves 30 at the appropriate position on the flexible patch 3. It has a more convenient adaptability for repairing the damaged area.
[0030] It should be noted that the bonding component 2 includes a sleeve 20, which is fixedly connected to the fixed outer ring 1. A spring seat 21 is fixedly installed inside the sleeve 20, and a telescopic spring 22 is fixedly installed inside the spring seat 21. A connecting plate 23 is fixedly installed at the end of the telescopic spring 22 away from the spring seat 21. A slider 25 is fixedly installed on the outer wall of the connecting plate 23. A connecting screw 26 is fixedly installed at the end of the connecting plate 23 away from the telescopic spring 22. A limiting slide rail 24 is fixedly installed on the inner wall of the sleeve 20. The slider 25 is slidably connected to the inside of the limiting slide rail 24. Threaded grooves 30 are opened on the opposite sides of the two flexible patches 3. The connecting screw 26 is connected to the threaded grooves 30. The telescopic spring 22 can push the connecting plate 23, slider 25 and connecting screw 26 to move when it resets. The connecting screw 26 is connected to the flexible patch 3. Since the flexible patch 3 and the fixed outer ring 1 are designed separately, they can be adapted to the damaged area for sealing. Similarly, the telescopic spring 22 can also reset after the fixed outer ring 1 is fixed to the outside of the pipe. It can effectively push the flexible patch 3 to the damaged area for sealing. It can adapt to pipes of different diameters. The telescopic spring 22 can effectively reduce the impact of the pressure carried by the leaked gas or liquid on the flexible patch 3, so that the pipe body can form a sealed space for normal transportation, thereby improving the sealing performance of the seal.
[0031] Both ends of the two fixed outer rings 1 are fixedly installed with connecting pieces 4. Each of the four connecting pieces 4 has two threaded holes. Each of the four connecting pieces 4 has a connecting bolt 5 threaded inside. Each of the four connecting bolts 5 has a positioning nut 50 threaded outside. Since the actual sealing method of the pipe seal relies on the flexible patch 3, the main function of the fixed outer ring 1 is to rigidly fix it to prevent the gas and liquid pressure from opening the flexible patch 3. The connection between the two fixed outer rings 1 is achieved by connecting the connecting bolt 5 and the connecting piece 4. Therefore, the distance between the two fixed outer rings 1 can be changed by adjusting the connection point of the connecting bolt 5, so as to adapt to pipes of different diameters for installation. After the fixed outer ring 1 is fixedly installed, the telescopic spring 22 pops out to make the two flexible patches 3 form a closed ring structure to seal the pipe damage.
[0032] In addition, the limiting slide rail 24 is L-shaped, which can effectively prevent the slider 25 from derailing and ensure that the movement trajectory of the connecting screw 26 is accurately fixed.
[0033] Working principle: First, select a flexible patch 3 of appropriate size according to the area of the pipe rupture. Connect the flexible patch 3 to the two fixed outer rings 1 through the connecting screw 26. Install the two fixed outer rings 1 on the outside of the pipe rupture. Connect the connecting pieces 4 at both ends of the two fixed outer rings 1 through the connecting bolts 5. The connecting bolts 5 can change the distance between the two fixed outer rings 1 to adapt to pipes of different diameters. After installation, install the positioning nut 50 to form a rigid fixation. At this time, the telescopic spring 22 returns to its original position and pushes the connecting screw 26 and the flexible patch 3 to move, so that the two flexible patches 3 form a closed ring structure, thus sealing the pipe rupture.
[0034] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
