Description

Technical Field

[0001] This application relates to the technical field of pipe fittings, and in particular to a pipe repair fitting device. Background Technology

[0002] Flexible joints are crucial components connecting water supply pipelines. Their primary function is to provide deflection and flexibility, absorbing vibrations and deformations within the pipeline, thus buffering and protecting the safe operation of the water pipes. This reduces the pressure exerted by the pipeline on fixed supports and buildings, lowers the transmission pressure, ensures the safe operation of the water supply pipeline, extends the service life of the pipes, and reduces maintenance costs.

[0003] Currently, common flexible joints are mainly divided into rubber flexible joints or corrugated pipe flexible joints. For example, the utility model patent with publication number CN202674636U discloses a flexible joint for the outlet pipe of a water supply equipment. The flexible joint includes a flexible pipe and two flanges installed at both ends of the flexible pipe. The middle section of the flexible pipe is a spiral pipe, and the pipe wall of the flexible pipe is provided with spiral reinforcing ribs. The center of the two flanges is provided with a pipe hole to accommodate the flexible pipe. The periphery of the pipe hole is provided with an annular retaining groove. Both ends of the flexible pipe have outwardly turned flanges, which are fitted into the retaining grooves.

[0004] Flexible joints may become damaged after prolonged use, requiring replacement or repair. However, current common replacement and repair procedures involve shutting off the water supply by closing the valve, removing the flexible joint from the pipe, installing a new one, and finally reopening the valve to reconnect the water supply. This process results in prolonged water supply interruptions, impacting the water supply to residents along the affected pipeline. Summary of the Invention

Then, the first control valve is controlled to cut off the medium flow between the pipe body and the joint body, and then the second control valve is controlled to open the medium flow between the branch pipe and the pipe body, allowing water to flow through the pipe body, branch pipe, and connecting pipe, bypassing the joint body. The joint body is then removed from the pipe body for replacement and repair. This ensures that the water flow in the water supply pipeline is not interrupted during the replacement and repair process, preventing disruption to residents' water supply along the pipeline.

[0042] The following is in conjunction with the appendix Figure 1 - Appendix Figure 9 This application will be described in further detail below.

[0043] Example 1

[0044] This embodiment discloses a pipe repair joint device.

[0045] Reference Figures 1 to 5 A pipe repair fitting device includes a fitting body 10, a first control valve 30, a second control valve 40, and a connecting pipe 80. Both ends of the fitting body 10 are detachably fitted with pipe bodies 20 via third connectors 16, which can be bolts, nuts, or other connecting components. Branch pipes 21 are provided on the pipe bodies 20. The first control valves 30 are respectively located on the pipe bodies 20 at both ends of the fitting body 10, and are used to control the connection between the pipe bodies 20 and the fitting body 10. The second control valves 40 are located on the branch pipes 21, and are used to control the connection between the branch pipes 21 and the pipe bodies 20. Both ends of the connecting pipe 80 can be detachably connected to the branch pipes 21 on the pipe bodies 20 at both ends of the fitting body 10. The connecting pipe 80 can be a flexible pipe.

[0046] In use, the pipe repair connector device of this embodiment connects the pipe bodies 20 at both ends of the connector body 10 to the water supply pipe 90 via the seventh connector 150, which can be bolts, nuts, or other connecting components. During normal water supply, the first control valve 30 is in the on state, and the second control valve 40 is in the closed state, allowing water in the water supply pipe 90 to flow through the pipe bodies 20 and the connector body 10. When the connector body 10 is damaged and needs to be replaced or repaired, firstly, connect both ends of the connecting pipe 80 to the branch pipes 21 on the pipe bodies 20 at both ends of the connector body 10. Then, control the first control valve 30 to cut off the medium flow between the pipe body 20 and the connector body 10, and then control the second control valve 40 to open the medium flow between the branch pipe 21 and the pipe body 20, allowing water to flow through the pipe body 20, branch pipe 21, and connecting pipe 80, bypassing the connector body 10. Finally, remove the connector body 10 from the pipe body 20 for replacement or repair. This ensures that the water flow in the water supply pipe 90 is not interrupted during the replacement and repair of the connector body 10, thus preventing the water supply to residents along the pipeline from being affected.

[0047] Reference Figure 1 and Figure 3 In an optional embodiment, the connector body 10 may have the following structure: the connector body 10 includes an inner tube 11, an outer tube 12 and a sealing sleeve 13. Both the inner tube 11 and the outer tube 12 are made of metal. The inner tube 11 and the outer tube 12 are inserted into each other and can slide relative to each other along the axial direction. The outer peripheral wall of the inner tube 11 and the inner peripheral wall of the outer tube 12 are spaced apart.

[0048] The outer tube 12 is provided with a limiting member to prevent the inner tube 11 from separating from the outer tube 12. More specifically, the limiting member includes a retaining ring 14 and a retaining spring 15. The inner peripheral wall of the outer tube 12 is provided with an annular groove. The retaining ring 14 and the retaining spring 15 are engaged in the annular groove. The retaining ring 14 is located outside the retaining spring 15. The retaining ring 14 can be made of rubber. The outer peripheral part of the inner tube 11 is provided with an annular boss 111 that can abut against the retaining spring 15.

[0049] The sealing sleeve 13 is fixed to the inner circumferential wall of the outer pipe 12 and fits snugly against the outer side of the inner pipe 11. The pipe body 20 is connected to both the inner pipe 11 and the outer pipe 12. The sealing sleeve 13 can be made of rubber. Because the inner pipe 11 and the outer pipe 12 are inserted together and can slide relative to each other axially, they have axial expansion and contraction, which can absorb the axial vibration of the water supply pipe 90. At the same time, because the outer circumferential wall of the inner pipe 11 is spaced apart from the inner circumferential wall of the outer pipe 12, and the sealing sleeve 13 is provided for buffering, the radial vibration of the water supply pipe 90 can be absorbed.

[0050] Reference Figure 1 and Figure 2 In this embodiment, the first control valve 30 and the second control valve 40 can each adopt the following structure: The first control valve 30 includes a first valve plate 31 and a first screw 32. The first valve plate 31 is slidably disposed on the pipe body 20 and is provided with a first screw hole 311. The first screw 32 is rotatably disposed on the pipe body 20 and is screwed to the first valve plate 31 through the first screw hole 311. By rotating the first screw 32, the first valve plate 31 can be controlled to slide radially along the pipe body 20, thereby achieving the purpose of controlling the flow between the pipe body 20 and the connector body 10.

[0051] The second control valve 40 includes a second valve plate 41 and a second screw 42. The second valve plate 41 is slidably disposed on the branch pipe 21 and has a second screw hole 411. The second screw 42 is rotatably disposed on the branch pipe 21 and is screwed to the second valve plate 41 through the second screw hole 411. By rotating the second screw 42, the second valve plate 41 can be controlled to slide radially along the branch pipe 21, thereby achieving the purpose of controlling the flow between the branch pipe 21 and the pipe body 20.

[0052] Example 2

[0053] This embodiment discloses a pipe repair joint device.

[0054] Reference Figure 6 and Figure 7A pipe repair joint device, the difference between this embodiment and embodiment 1 is that it also includes a hose 50 and two sets of disassembly and assembly mechanisms. The disassembly and assembly mechanism includes a splitting and connecting component 60 and a draining component 70. The splitting and connecting component 60 can be detachably installed on the water supply pipe 90. The splitting and connecting component 60 is used to connect the end of the flexible joint 100 or the pipe body 20 that needs to be replaced. The draining component 70 can be connected to the end of the water supply pipe 90. The two ends of the hose 50 are respectively connected to the draining components 70 of the two sets of disassembly and assembly mechanisms.

[0055] When the flexible joint 100 made of materials such as rubber or corrugated pipe in the prior art is damaged, it can be replaced by the pipe repair joint device of this application. The specific replacement principle is as follows: First, install the split-connect component 60 on the water supply pipe 90. Then, connect the split-connect component 60 to the end of the flexible joint 100 and separate the end of the flexible joint 100 from the end of the water supply pipe 90. Next, connect the drainage component 70 to the end of the water supply pipe 90, so that the water in the water supply pipe 90 flows through the hose 50. Then, connect the split-connect component 60 to the end of the pipe body 20, separate the drainage component 70 from the end of the water supply pipe 90, and connect the end of the pipe body 20 to the end of the water supply pipe 90, so that the water flows through the pipe body 20 and the joint body 10. Finally, remove the split-connect component 60 from the water supply pipe 90 to complete the replacement of the flexible joint 100. During the replacement process, the water flow is diverted through the diversion component 70 and the hose 50, thereby reducing the time of water flow interruption and minimizing the impact of the replacement process on residents' normal water use.

[0056] Reference Figures 6 to 8 In an optional embodiment, the splitting assembly 60 may adopt the following structure: the splitting assembly 60 includes a base 61, a sliding sleeve 62, an end plate 63 and a first sliding drive component. The base 61 can be detachably installed on the water supply pipe 90. More specifically, the base 61 may adopt a split structure, and the split structure base 61 is detachably connected by a first connector 613. The first connector 613 may be a bolt, nut or other connector. A retaining ring 612 may be provided on the split structure base 61, and the base 61 can be fixedly installed on the water supply pipe 90 by the retaining ring 612.

[0057] The sliding sleeve 62 is slidably mounted on the outside of the base 61. The sliding sleeve 62 can be a split structure, and the split structure of the sliding sleeve 62 is detachably connected by the second connecting member 625. The second connecting member 625 can be a bolt, nut or other connecting member.

[0058] The first sliding drive component is disposed on the base 61 and connected to the sliding sleeve 62. More specifically, the first sliding drive component includes a third screw 64. The sliding sleeve 62 is provided with a guide rod 621, which slides through the base 61. The base 61 is provided with a third screw hole 611. The third screw 64 is screwed to the base 61 through the third screw hole 611 and is rotatably connected to the sliding sleeve 62.

[0059] The end plate 63 is detachably connected to the sliding sleeve 62. The end plate 63 can be a split structure, and the split end plate 63 is detachably connected to the sliding sleeve 62 through the fifth connector 120. The fifth connector 120 can be a bolt or other connector. The end plate 63 is used to connect the end of the flexible joint 100 or the pipe body 20 that needs to be replaced.

[0060] Reference Figures 7 to 9 The drainage component 70 is disposed on the sliding sleeve 62. In an optional embodiment, the drainage component 70 may have the following structure: the drainage component 70 includes a drainage seat 71 and a second sliding drive member. The sliding sleeve 62 is provided with a sliding groove 622, the drainage seat 71 is slidably disposed in the sliding groove 622, and the second sliding drive member is disposed on the sliding sleeve 62 and connected to the drainage seat 71. More specifically, the second sliding drive member includes a fourth screw 72, the sliding sleeve 62 is provided with a fourth screw hole 624, the fourth screw 72 is screwed to the sliding sleeve 62 through the fourth screw hole 624, and is rotatably connected to the drainage seat 71.

[0061] The flow seat 71 is provided with a flow channel that can communicate with the end of the water supply pipe 90 and the hose 50. More specifically, the flow channel includes a channel 711 provided on the flow seat 71 and a first flow port 712 and a second flow port 713 communicating with the channel 711. The first flow port 712 can communicate with the end of the water supply pipe 90. The sliding sleeve 62 is provided with a third flow port 623 that can communicate with the second flow port 713. The hose 50 communicates with the third flow port 623.

[0062] The implementation principle of the pipe repair joint device in this embodiment is as follows: (Refer to...) Figures 6 to 8 A first flange plate 91 is provided at the end of the water supply pipe 90, and a second flange plate 101 is provided at the end of the existing flexible joint 100. The first flange plate 91 and the second flange plate 101 are connected by a fourth connector 110, which can be a bolt, nut or other connector.

[0063] When it is necessary to replace or repair the existing flexible joint 100, first fix the base 61 on the water supply pipe 90, and connect the sliding sleeve 62 and end plate 63 to the base 61, and make the end of the base 61 abut against the first flange plate 91, and make the end plate 63 abut against the second flange plate 101. Then, use welding or other means to fix the end plate 63 and the second flange plate 101 together.

[0064] Next, the fourth connector 110 is removed, and the third screw 64 is rotated to drive the sliding sleeve 62 to slide, causing the end plate 63 and the second flange plate 101 to move away from the base 61, separating the second flange plate 101 from the first flange plate 91. Then, the fourth screw 72 is rotated to drive the drain seat 71 to move between the first flange plate 91 and the second flange plate 101, until the first flow port 712 is aligned with the end of the water supply pipe 90, and the second flow port 713 is aligned with the third flow port 623. Next, the third screw 64 is rotated to drive the sliding sleeve 62 to slide until the drain seat 71 abuts against the first flange plate 91, allowing water in the water supply pipe 90 to flow sequentially through the first flow port 712, channel 711, second flow port 713, and third flow port 623 before entering the hose 50. The hose 50 bridges and drains the water supply pipes 90 at both ends of the flexible joint 100, preventing water supply interruption.

[0065] Next, remove the fifth connecting piece 120, separate the end plate 63 from the sliding sleeve 62, and then disassemble and separate the second flange plate 101 from the end plate 63. (Refer to...) Figure 4 and Figure 5 Next, the pipe body 20 is connected to the end plate 63. More specifically, a third flange plate 22 is provided at the end of the pipe body 20. The third flange plate 22 can be connected to the end plate 63 through connecting parts such as studs 221 and nuts 140. Then, the end plate 63 is connected to the sliding sleeve 62. At this time, the first valve plate 31 is in the closed state and the second valve plate 41 is in the open state. Next, the fourth screw 72 is rotated to drive the flow guide seat 71 to reset into the sliding groove 622. Then, the third screw 64 is rotated to drive the sliding sleeve 62 to slide, so that the first flange plate 91 and the third flange plate 22 abut against each other, and the third flange plate 22 is connected to the first flange plate 91 through the sixth connecting part 130. At this time, the water in the water supply pipe 90 flows through the pipe body 20 and the branch pipe 21 and enters the connecting pipe 80. The water flow is bridged and guided through the connecting pipe 80 to avoid water supply interruption. Next, connect the connector body 10 to the pipe body 20, connect the first valve plate 31, close the second valve plate 41, remove the connecting pipe 80, and remove the split assembly 60 and the drainage assembly 70 from the water supply pipe 90 to complete the replacement and repair of the flexible connector 100.
