Technical Field

[0001] The utility model relates to the field of pipe body maintenance tools, in particular to a leakage pipe body maintenance device. Background Art

[0002] The pipe body is a commonly used fluid transportation tool in daily life. Under long-term use and external damage, the pipe body is prone to leakage, and the fundamental cause of the leakage is the fracture of the pipe body, which needs to be repaired in time.

[0003] In the past, the repair of the leakage part of the pipe body needs to be selected according to the material of the pipe body. For example, the metal material is repaired by welding, and the plastic material is repaired by winding waterproof tape. No matter which repair method is used, if the pipe body belongs to a hidden design or the operating space around the pipe body is insufficient, as long as at least one side of the fracture surface of the pipe body is close to the fixture, it will affect the normal progress of the repair. The repair process is not only time-consuming and laborious, but also the repair effect cannot be guaranteed.

[0004] Taking the finned tube cooler as an example, when the finned tube leaks, the cooler should be shut down before repair, the internal water or liquid should be drained, the position where the fracture of the pipe body occurs and leaks should be found, and the leaking pipe body should be welded and repaired. Due to the narrow operating space around the leaking pipe body, the welding difficulty increases, and the welding effect will be affected, seriously affecting the operation and service life of the equipment.

[0005] Therefore, there is an urgent need for a leakage pipe body maintenance device that can improve the repair convenience on the basis of ensuring the repair effect. Summary of the Invention

[0006] The purpose of the utility model is to provide a leakage pipe body maintenance device to solve the problems existing in the above-mentioned prior art. The part of the leaking pipe body that is fractured is replaced by a replacement pipe body and a flexible plug, which can ensure the repair effect and improve the repair convenience at the same time.

[0007] To achieve the above purpose, the utility model provides the following scheme: The utility model provides a leakage pipe body maintenance device, including a replacement pipe body and a flexible plug. The replacement pipe body is arranged between the two fracture ends of the leaking pipe body. The flexible plugs are arranged at both axial ends of the replacement pipe body. The flexible plugs are hollow. The inner cavity of the flexible plug communicates with the leaking pipe body and the replacement pipe body. The flexible plug abuts against the fracture end of the leaking pipe body for sealing, and one end of the flexible plug close to the replacement pipe body abuts against the port of the replacement pipe body for sealing.

[0008] Preferably, a threaded section is arranged on the outer peripheral wall of the replacement pipe body. One end of the threaded section is flush with one end of the replacement pipe body. The threaded section is threadedly connected with a first adjusting member, and the inner diameter of the first adjusting member is smaller than the outer diameter of the flexible plug.

[0009] Preferably, an abutting member is provided at one end of the replacement pipe body away from the first adjusting member. The end face of the abutting member is flush with the end face of the replacement pipe body, and the abutting member axially covers the pipe orifice of the leakage pipe body.

[0010] Preferably, the abutting member is a second adjusting member. The axial length of the threaded section is the same as the axial length of the replacement pipe body. The threaded section is threadedly connected to the first adjusting member and the second adjusting member.

[0011] Preferably, a hollow extension part is provided on the axial end face of the first adjusting member. The inner peripheral wall of the extension part is threadedly connected to the threaded section.

[0012] Preferably, the extension part is integrally provided with the first adjusting member.

[0013] Preferably, the volume of the extension part is smaller than the volume of the first adjusting member. The extension part is provided at one end of the first adjusting member close to the middle of the replacement pipe body.

[0017] The present utility model mainly achieves the following technical effects compared with the prior art:

[0018] Place the replacement pipe body between the two broken ends of the leakage pipe body, and use the flexible plug to seal the gap between the replacement pipe body and the broken ends of the leakage pipe body, then the repair of the leakage pipe body can be completed.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0025] The purpose of the present invention is to provide a leakage pipe body repair device to solve the problems existing in the prior art. By using a replacement pipe body and a flexible plug to replace the broken part of the leaking pipe body, while ensuring the repair effect, the repair convenience is improved.

[0026] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the drawings and specific implementation manners.

[0027] Please refer to as Figure 1As shown in the figure, a leakage pipe body repair device is provided, including a replacement pipe body 2 and a flexible plug 1. The replacement pipe body 2 is arranged between the two broken ends of the leaking pipe body. If the natural fracture distance of the leaking pipe body is small, the distance between the two broken ends can be enlarged by manual cutting. Flexible plugs 1 are arranged at both axial ends of the replacement pipe body 2. The flexible plugs 1 are hollow. The inner cavity of the flexible plug 1 communicates with the leaking pipe body and the replacement pipe body 2. The flexible plug 1 abuts and seals against the broken end of the leaking pipe body. One end of the flexible plug 1 close to the replacement pipe body 2 abuts and seals against the port of the replacement pipe body 2. The flexible plug 1 can abut against the end faces of the broken end of the leaking pipe body and the port of the replacement pipe body 2, partially insert into the broken end of the leaking pipe body and the port of the replacement pipe body 2, or wrap around the outer periphery of the broken end of the leaking pipe body and the port of the replacement pipe body 2. It only needs to seal the broken end of the leaking pipe body and the port of the replacement pipe body 2. By placing the replacement pipe body 2 between the two broken ends of the leaking pipe body and using the flexible plug 1 to block the gap between the replacement pipe body 2 and the broken end of the leaking pipe body, the leaking pipe body only needs to have a certain space on one side to complete the repair. The overall operation is less restricted by space, which is beneficial to improving the repair convenience and can ensure the repair effect. Moreover, after the repair, the fluid can flow normally.

[0028] Since the length between the two broken ends of the leaking pipe body after fracture or the two manually enlarged broken ends cannot be determined, a threaded section is provided on the outer peripheral wall of the replacement pipe body 2. One end of the threaded section is flush with one end of the replacement pipe body 2. A first adjusting member 3 is threadedly connected to the threaded section. The inner diameter of the first adjusting member 3 is smaller than the outer diameter of the flexible plug 1. During the process of screwing the first adjusting member 3 out of the replacement pipe body 2, the overall length of the replacement pipe body 2 including the first adjusting member 3 gradually increases. It can not only adapt to different fracture distances but also squeeze the flexible plugs 1 on both sides, thereby improving the sealing effect.

[0029] To increase the sealing effect between the end of the replacement pipe body 2 far from the first adjusting member 3 and the flexible plug 1, an abutting member 4 is provided at the end of the replacement pipe body 2 far from the first adjusting member 3. The end face of the abutting member 4 is flush with the end face of the replacement pipe body 2. The abutting member 4 axially covers the pipe orifice of the leaking pipe body, increasing the extrusion contact surface with the flexible plug 1.

[0030] Except that one side of the abutting member 4 close to the flexible plug 1 is a flat surface, the shapes of other surfaces are not limited. It can be directly welded, bonded or integrally provided on the replacement pipe body 2 according to the material, or it can be set as the second adjusting member, and a threaded section flush with the port is additionally provided on the replacement pipe body 2 for threaded connection with the second adjusting member, or the axial length of the threaded section is directly set to be the same as the axial length of the replacement pipe body 2, and the threaded section is threadedly connected to the first adjusting member 3 and the second adjusting member. When the abutting member 4 is the second adjusting member, it can also be used as a spare length adjusting member. When the first adjusting member 3 is screwed out to the maximum length, but the length of the replacement pipe body 2 still needs to be further increased, the length of the replacement pipe body 2 can be increased by the extension of the second adjusting member.

[0031] When the axial length of the threaded section is the same as the axial length of the replacement pipe body 2, the hollow screw can be directly used as the replacement pipe body 2.

[0032] A hollow lengthening part 5 is arranged on the axial end face of the first adjusting member 3, and the inner peripheral wall of the lengthening part 5 is threadedly connected to the threaded section. The arrangement of the lengthening part 5 can increase the maximum length of the first adjusting member 3 screwed out of the replacement pipe body 2, thereby increasing the adjustment range of the overall replacement pipe body 2 and improving the applicable range.

[0033] Similarly, when the abutting member 4 is the second adjusting member, a lengthening part 5 can also be arranged on the second adjusting member.

[0034] In order to improve the structural strength, the lengthening part 5 is integrally arranged with the first adjusting member 3.

[0035] In order to reduce the weight of the device, the volume of the lengthening part 5 is smaller than the volume of the first adjusting member 3, and the lengthening part 5 is arranged at one end of the first adjusting member 3 close to the middle of the replacement pipe body 2 to ensure that the first adjusting member 3 with a larger end face abuts and seals with the flexible plug 1.

[0036] The first adjusting member 3 and the second adjusting member can directly select nuts, so that a wrench can be used for screwing during maintenance, saving labor. Of course, a circular ring structure with anti-slip lines on the outer peripheral wall can also be selected, etc.

[0037] In this embodiment, in order to facilitate the insertion of the flexible plug 1 into the gap, the flexible plug 1 is set to be a frustum shape with a taper of 1:10 to 1:15.

[0038] The material of the flexible plug 1 can be determined according to the actual temperature and properties of the conveyed fluid, etc., and SBS thermoplastic rubber, polytetrafluoroethylene or silica gel, etc. can be selected.

[0039] When the second adjusting member is not integrally arranged with the replacement pipe body 2, the gap between the second adjusting member and the replacement pipe body needs to be sealed. Similarly, the tightness of the threaded connection part between the first adjusting member 3 and the replacement pipe body 2 also needs to be ensured, such as winding raw tape.

[0040] In the actual use process, taking the fin cooler as an example, first clean the fins 7 at the fracture leakage of the finned tube 6 to expose the fracture leakage. Enlarge the distance between the two broken ends of the finned tube 6 by manual cutting. When cutting, try to ensure that the broken ends are flat and smooth. At this time, insert the two flexible plugs 1 into the two broken ends respectively, place the replacement tube body 2 between the two flexible plugs 1, and use tools such as a wrench or manually screw the first adjusting member 3. As the first adjusting member 3 extends out of the replacement tube body 2, the overall length of the replacement tube body 2 carrying the first adjusting member 3 increases, thereby squeezing the flexible plugs 1 at both ends to complete the sealing. At this time, the repair is completed.

[0041] All adaptive changes made according to actual needs are within the protection scope of the present utility model.

[0042] It should be noted that for those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
