Description

Technical Field

[0001] The present application relates to the field of water pipeline installation, and in particular to a double anti-seepage installation method for water pipelines. Background Art

[0002] A water pipeline is a pipe used to transport water. A complete water pipeline is typically constructed by connecting several pipe fittings end to end. During construction, flanges are often used to connect these fittings end to end. However, using flanges to connect water pipes can easily lead to water leaking between the two flanges.

[0003] In order to reduce the probability of water seepage at the connection points between water pipes, raw tape is generally wrapped around the outside of the pipe joint before connecting it to the water pipe fittings to achieve a waterproofing effect.

[0004] However, if the raw tape is wrapped too little, it will not have the anti-seepage effect; if the raw tape is wrapped too much, it will be difficult to connect the pipe joint to the water pipe, and the raw tape will be easily damaged during the connection process, resulting in the inability to have the anti-seepage effect after installation.

[0041] An embodiment of the present application provides a double anti-seepage installation method for a water pipeline.

[0042] A double anti-seepage installation method for a water pipeline comprises the following steps:

[0043] S1: Insert the two ends of the connecting pipe 2 into the corresponding two water pipes 1 respectively;

[0044] S2: After the connecting pipe 2 is inserted, the self-locking component 3 will securely connect the connecting pipe 2 to the water pipe 1;

[0045] S3: During the self-locking process of the self-locking component 3, the first anti-seepage component and the second anti-seepage component will automatically press against the water pipe 1.

[0046] See also Figure 1 、 Figure 2 and Figure 3 The self-locking assembly 3 includes a ring block 31 and a plug rod 32. The ring block 31 is fixedly mounted on the connecting pipe 2 and is integrally formed with the connecting pipe 2. In the embodiment of the present application, a single ring pipe is provided, and two water pipes 1 share one ring block 31. A plug hole 11 is provided on the end wall of the water pipe 1 near the ring block 31. In the embodiment of the present application, there are four plug holes 11 in total, and the four plug holes 11 are evenly distributed along the circumference of the water pipe 1. One end of the plug rod 32 is fixed to the side wall of the ring block 31, and the other end is provided in the plug hole 11. After the plug rod 32 is inserted into the plug hole 11, the connecting pipe 2 and the water pipe 1 are not easily rotated relative to each other, thereby facilitating the subsequent fixed connection between the connecting pipe 2 and the water pipe 1.

[0047] See also Figure 4The self-locking assembly 3 includes a trigger rod 33, a trigger spring 34, a connecting rope 35, a locking rod 36, and a locking spring 37. A trigger hole 321 is defined in the end wall of the plug rod 32, which is away from the ring block 31. The trigger rod 33 is disposed within the trigger hole 321. One end of the trigger spring 34 is fixed to the end wall of the trigger rod 33, and the other end is fixed to the bottom of the trigger hole 321. The trigger spring 34 is used to push the trigger rod 33 out of the trigger hole 321. Before the connecting pipe 2 is inserted into the water pipe 1, the trigger rod 33, due to the configuration of the trigger spring 34, extends out of the trigger hole 321 at the end away from the trigger spring 34.

[0048] See also Figure 4 The outer wall of the connecting pipe 2 is provided with a receiving hole 21, and the inner wall of the water pipe 1 is provided with a locking hole 12. When the connecting pipe 2 is inserted into the water pipe 1, the receiving hole 21 and the locking hole 12 are coaxial. One end of the locking rod 36 is disposed in the receiving hole 21, and the other end is disposed in the locking hole 12. One end of the locking spring 37 is fixed to the locking rod 36, and the other end is fixed to the bottom of the receiving hole 21. In this embodiment of the present application, the elastic force of the trigger spring 34 is greater than the elastic force of the locking spring 37, ensuring that the locking rod 36 is located in the receiving hole 21 before the connecting pipe 2 is inserted into the water pipe 1.

[0049] See also Figure 4 One end of the connecting rope 35 is fixed to the end wall of the trigger rod 33 near the trigger spring 34, while the other end extends into the accommodating hole 21 and is fixed to the end wall of the locking rod 36 near the locking spring 37. After the plug rod 32 is inserted into the plug hole 11, the trigger rod 33 is pressed back into the trigger hole 321. At this time, the connecting rope 35 is released, and the locking spring 37 can push the locking rod 36 into the locking hole 12, thereby completing the quick installation connection between the connecting pipe 2 and the water pipe 1, improving installation efficiency. In this embodiment of the application, the connecting pipe 2 and the water pipe 1 are not easily disassembled.

[0050] See also Figure 4 The first anti-seepage component includes: a sealing part 4, a slow-pushing part 5 and a limiting part 6.

[0051] See also Figure 4 The sealing portion 4 includes a first sealing ring 41 and multiple receiving plates 42. The outer wall of the connecting pipe 2 is provided with an annular groove 22. In the embodiment of the present application, there are four receiving plates 42, each of which is arc-shaped. When connected together, the four receiving plates 42 can encircle the annular groove 22. The receiving plates 42 are evenly slidably arranged within the chute along the circumference of the annular groove 22 and slide in a direction away from the center of the connecting pipe 2, that is, toward the inner wall of the water pipe 1.

[0052] See also Figure 4The first sealing ring 41 is fixedly mounted on the four receiving plates 42, and the first sealing ring 41 is tightly pressed against the inner wall of the water pipe 1. The first sealing ring 41 can improve the sealing between the connecting pipe 2 and the water pipe 1, so that leakage is not likely to occur.

[0053] See also Figure 4 The slow-push portion 5 comprises a push rod 51, a threaded barrel 52, and a coil spring 53. The threaded barrel 52 is rotatably mounted within the annular groove 22. The coil spring 53 is sleeved onto the threaded barrel 52, with one end secured to the sidewall of the threaded barrel 52 and the other end secured to the interior of the annular groove 22. Before the connecting pipe 2 is inserted into the water pipe 1, the threaded barrel 52 is rotated to ensure that the coil spring 53 is in a charged state. One end of the push rod 51 is secured to the side of the receiving plate 42 facing away from the first sealing ring 41, and the other end is threadedly connected to the threaded barrel 52.

[0054] See also Figure 4 The limiting part 6 includes: a limiting rod 61, a limiting spring 62 and a limiting rope 63. A placement hole 23 is opened on the inner side wall of the annular groove 22 near the accommodating hole 21, and a limiting block is opened on the outer side wall of the threaded cylinder 52 for inserting the limiting rod 61. One end of the limiting rod 61 is set in the placement hole 23. Before the connecting pipe 2 is not inserted into the water pipe 1, the other end of the limiting rod 61 is inserted into the limiting hole 521, so that the elastic force stored in the coil spring 53 is not easily released, thereby making it difficult to drive the threaded cylinder 52 to rotate.

[0055] See also Figure 4 One end of the limit spring 62 is fixed to the end wall of the limit rod 61 away from the threaded barrel 52, and the other end is fixed to the bottom of the placement hole 23. In this embodiment of the present application, the elastic force of the locking spring 37 is greater than the elastic force of the limit spring 62. One end of the limit rope 63 is fixed to the end wall of the limit rod 61 near the limit spring 62, and the other end extends into the accommodating hole 21 and is fixed to the end wall of the locking rod 36 near the locking spring 37.

[0056] Before the connecting pipe 2 is inserted into the water pipe 1, the threaded barrel 52 is rotated to ensure that the coil spring 53 is in a charged state, and the limiting rod 61 is inserted into the limiting hole 521 by the thrust of the limiting spring 62 to limit the threaded barrel 52, so that the threaded barrel 52 is not easily rotated due to the release of the elastic force of the coil spring 53;

[0057] After the connecting pipe 2 is inserted into the water pipe 1, the locking rod 36 is inserted into the locking hole 12; during the insertion of the locking rod 36, the limiting rope 63 is pulled to pull the limiting rod 61, so that the limiting rod 61 will be separated from the limiting hole 521; at this time, the elastic force of the coil spring 53 is released to drive the threaded barrel 52 to rotate, and the rotation of the threaded barrel 52 drives the push rod 51 to push the receiving plate 42, so that the first sealing ring 41 is in close contact with the inner wall of the water pipe 1, so as to improve the gap between the water pipe 1 and the connecting pipe 2. Sealing; and after the first sealing ring 41 is in close contact with the inner side of the water pipe 1, the threaded barrel 52 still has a tendency to rotate, so that the push rod 51 still has a tendency to push the receiving plate 42. Therefore, once the first sealing ring 41 is not in close contact with the inner side wall of the water pipe 1 due to aging or other reasons, the push rod 51 can push the receiving plate 42 to make the first sealing ring 41 and the inner side of the water pipe 1 tightly pressed, thereby ensuring good sealing between the connecting pipe 2 and the water pipe 1, so as to prevent leakage;

[0058] Furthermore, the first sealing ring 41 does not need to be sleeved on the outer wall of the connecting pipe 2 , thereby preventing the connecting pipe 2 from being inserted into the water pipe 1 and preventing the first sealing ring 41 from being damaged.

[0059] See also Figure 4 Furthermore, a supporting assembly 9 is provided between the inner wall of the connecting tube 2 and the threaded barrel 52. The supporting assembly 9 comprises a supporting plate 91, a supporting rod 92, a closed tube 93, a sliding plate 94, and a rubber sleeve 95. The closed tube 93 is fixed to the inner wall of the connecting tube 2, and a water inlet hole 931 is formed through the outer wall of the closed tube 93 to facilitate water inflow into the closed tube 93. The sliding plate 94 is slidably connected to the closed tube 93 and slides along the length of the closed tube 93. In the embodiment of the present application, when the sliding plate 94 slides to the bottom, the water inlet hole 931 is still located on the side of the sliding plate 94 located on the threaded barrel 52.

[0060] See also Figure 4 The support plate 91 is slidably connected to the annular groove 22, corresponding one-to-one with the receiving plate 42. A mounting hole 911 is defined on the side of the support plate 91 closest to the receiving plate 42. The threaded barrel 52 is rotatably mounted within the mounting hole 911. The end of the coil spring 53, facing away from the threaded barrel 52, is secured to the inner wall of the mounting hole 911. One end of the supporting rod 92 is secured to the side of the support plate 91 facing away from the receiving plate 42, while the other end extends through the sealing tube 93 and is secured to the sliding plate 94.

[0061] See also Figure 4 The rubber sleeve 95 is fixedly mounted on the top support rod 92 and the sliding plate 94 . The rubber sleeve 95 can improve the sealing between the top support rod 92 and the connecting pipe 2 , as well as the sealing between the sliding plate 94 and the inner wall of the closing pipe 93 .

[0062] During the water delivery process of the water pipe 1, the water source can flow into the closed tube 93 through the water inlet hole 931 to squeeze the sliding plate 94, so that the sliding plate 94 has a tendency to slide toward the side close to the receiving plate 42; at this time, the top support rod 92 has a tendency to push the support plate 91, thereby pushing the receiving plate 42, so that the first sealing ring 41 and the inner side of the water pipe 1 are tightly attached, that is, the first sealing ring 41 is subjected to a double compression trend, thereby ensuring that the first sealing ring 41 can always be pressed against the inner side of the water pipe 1 to ensure sealing, so that leakage is not easy to occur.

[0063] See also Figure 5 The second anti-seepage component includes: an anti-seepage part 7 and a pressing part 8.

[0064] The anti-seepage part 7 includes: a collar 71, a connecting rod 72, a bellows 73, a second sealing ring 74 and a plurality of pressure plates 75. The collar 71 is sleeved on the water pipe 1. One end of the connecting rod 72 is fixed to the collar 71 and the other end is fixed to the ring block 31. During the process of inserting the connecting pipe 2 into the water pipe 1, the collar 71 is sleeved on the water pipe 1. An anti-seepage groove 711 is provided on the inner wall of the collar 71, and the anti-seepage groove 711 is annular. In the embodiment of the present application, four pressure plates 75 are provided and are arc-shaped. The four pressure plates 75 can be spliced ​​together to wrap around the water pipe 1. The four pressure plates 75 are evenly slid in the anti-seepage groove 711 along the circumference of the anti-seepage groove 711 and slide along the axis perpendicular to the collar 71.

[0065] See also Figure 5 The second sealing ring 74 is fixed to the side of the four compression plates 75 near the outer wall of the water pipe 1. The second sealing ring 74 abuts against the outer wall of the water pipe 1 to improve the sealing between the collar 71 and the outer wall of the water pipe 1. The bellows 73 is fixed between the ring block 31 and the collar 71. The arrangement of the first sealing ring 41 and the bellows 73 forms a second barrier, further improving the anti-seepage effect.

[0066] See also Figure 5 The pressing portion 8 includes a lower pressing rod 81, a push rod 82, a push spring 83, and a release rope 84. The lower pressing rod 81 is fixed to the side of the pressing plate 75 that faces away from the second sealing ring 74. A guide surface 811 is provided on the end of the lower pressing rod 81 away from the pressing plate 75. The guide surface 811 is inclined, and the end of the guide surface 811 near the connecting rod 72 is inclined downward. A push hole 721 is formed in the end wall of the connecting rod 72 near the collar 71. A through hole 712 is provided between the push hole 721 and the anti-seepage groove 711.

[0067] See also Figure 5One end of the push rod 82 is disposed within the push hole 721, while the other end passes through the through hole 712, extends into the anti-seepage groove 711, and abuts against the guide surface 811. One end of the push spring 83 is fixed to the end wall of the push rod 82 away from the pressing rod 81, and the other end is fixed to the bottom of the push hole 721. In this embodiment of the present application, the elastic force of the push spring 83 is less than the elastic force of the trigger spring 34. One end of the release rope 84 is fixed to the end wall of the push rod 82 near the push spring 83, and the other end passes through the trigger hole 321 and is fixed to the end wall of the trigger rod 33 near the trigger spring 34.

[0068] After the connecting pipe 2 is inserted into the water pipe 1, the trigger rod 33 is pressed back into the trigger hole 321. At this time, the release rope 84 is released, and then the push spring 83 can push the push rod 8251 to slide toward the anti-seepage groove 711 until the push rod 82 abuts against the guide surface 811, thereby pressing the lower pressure rod 81; the lower pressure rod 81 will have a pushing tendency on the clamping plate 75, so that the clamping plate 75 can press the second sealing ring 74 against the outer wall of the water pipe 1 to ensure that the second sealing ring 74 is always pressed against the outer wall of the water pipe 1, thereby improving the sealing between the ring 71 and the outer wall of the water pipe 1.

[0069] The working principle of the double anti-seepage installation method for water pipes of the present application is as follows when in use: after the connecting pipe 2 is inserted into the water pipe 1, the trigger rod 33 is pressed back into the trigger hole 321. At this time, the release rope 84 is released, and then the push spring 83 can push the push rod 82 to slide toward the anti-seepage groove 711 until the push rod 82 abuts against the guide surface 811, thereby causing pressure on the lower pressure rod 81; the lower pressure rod 81 will have a pushing tendency on the clamping plate 75, so that the clamping plate 75 can press the second sealing ring 74 on the outer wall of the water pipe 1 to ensure that the second sealing ring 74 is always pressed on the outer wall of the water pipe 1, thereby improving the sealing between the ring 71 and the outer wall of the water pipe 1.

[0070] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
