Description

Technical Field

[0001] This application relates to the field of pipe connections, and in particular to a fluid pipe clamping clamp and a method for installing the clamp. Background Technology

[0002] A fluid pipe is a steel pipe with a hollow cross-section and no welds from beginning to end. While a hollow cross-section is mandatory, it can also be square, triangular, or any other shape. Some equipment requires rectangular pipes due to constraints, but the vast majority use circular pipes. Circular pipes have the smallest perimeter-to-area ratio among all geometric cross-sections, meaning that the largest internal cross-section can be obtained using the same amount of material.

[0003] Traditional pipelines typically use an intermediate ring and two side rings for connection. The intermediate ring is placed between two pipes, and then one side ring is fitted between the intermediate ring and one of the pipes and connected with bolts. Then, the other side ring is fitted between the intermediate ring and the other pipe and connected with bolts, thus achieving the connection and fixation between the two pipes.

[0004] Regarding the aforementioned technologies, the inventors believe that due to the long length of the pipeline, it takes a lot of time and effort to fit the side ring onto the outside of the pipeline, resulting in the installation of the pipeline clamp being time-consuming and labor-intensive. Summary of the Invention

[0005] To improve the installation efficiency of pipe clamps, this application provides a fluid pipe snap-fit ​​clamp and a method for installing the clamp.

[0006] Firstly, this application provides a fluid pipeline clamping clamp, which adopts the following technical solution:

[0007] A fluid pipeline clamping clamp includes an intermediate ring and a side ring that mates with the pipeline body. An annular groove is formed on the inner side of the side ring near the intermediate ring. The pipeline body is provided with a clamping assembly that engages with the annular side groove. The side ring includes two semicircular rings that can be fitted onto the outside of the pipeline body. An inner connecting block and an outer connecting block are respectively provided at opposite ends of the semicircular rings. Adjacent semicircular rings are connected by a connector. The outer connecting block has a slot, and the inner connecting block has a plug that engages with the slot.

[0008] By adopting the above technical solution, when assembling two semicircular rings, first put the two semicircular rings on the outside of the pipe body, combine the two semicircular rings into a side ring, and insert the insert of the inner connecting block into the slot of the outer connecting block, thereby completing the assembly of the side ring. The setting of the insert and slot not only facilitates the rapid assembly of the side ring, but also improves the connection stability between the two semicircular rings during the use of the side ring.

[0009] Optionally, an auxiliary component is provided at the end of the semicircular ring away from the outer connecting block, and an auxiliary groove is provided at the position of the semicircular ring near the inner connecting block. The auxiliary groove includes an auxiliary spring disposed in the auxiliary groove and a wedge block disposed at one end of the auxiliary spring. An auxiliary sliding groove is provided at the end of the outer connecting block to engage with the wedge block.

[0010] By adopting the above technical solution, two semicircular rings are placed on the outside of the pipe body, one in front of the other, so that the wedge block is completely located in the auxiliary groove. The insert of the inner connecting block is inserted into the slot of the outer connecting block. The wedge block is inserted into the auxiliary slide groove under the push of the auxiliary spring. The setting of the auxiliary component can improve the connection stability between the two semicircular rings.

[0011] Optionally, the snap-fit ​​assembly includes a snap-fit ​​ring circumferentially disposed on the pipe body and a snap-fit ​​sealing ring disposed on the side of the snap-fit ​​ring near the middle ring. Both the snap-fit ​​ring and the snap-fit ​​sealing ring are snap-fitted into the annular side groove. A displacement groove is formed on the inner side of the middle ring near the side ring. The closer the displacement groove is to the side ring, the greater the distance between the inner wall of the displacement groove and the pipe body. A rubber ring of the same shape is disposed in the displacement groove.

[0012] By adopting the above technical solution, when the pipeline body is at a high temperature, the expansion of the pipeline body will compress the rubber ring, and the rubber ring will compress the rigid outer ring, so that the rigid outer ring can be displaced slightly closer to the edge ring, thereby reducing the impact of the expansion of the pipeline body on the intermediate ring.

[0013] Optionally, a space is reserved between the annular side groove and the snap ring, and toothed belt rings are provided on the side wall of the annular side groove and the outer side of the snap ring, and the two toothed belt rings mesh with each other.

[0014] By adopting the above technical solution, when the pipe body is in a low-temperature environment, the pipe body will shrink slightly. Due to the two toothed belt rings, the circumferential displacement between the pipe body and the side ring can be reduced.

[0015] Optionally, the snap-fit ​​sealing ring is hollow inside.

[0016] By adopting the above technical solution, the hollow snap-fit ​​sealing ring gives it greater deformation capability.

[0017] Optionally, a plurality of plastic partition plates are provided circumferentially on the outer side of the pipe body. The plastic partition plates are located between the rubber ring and the snap-fit ​​sealing ring, and the cross-section of the plastic partition plates is triangular.

[0018] By adopting the above technical solution, the plastic separator can, to a certain extent, prevent the rubber ring from dislodging from the displacement groove under normal circumstances. Setting the plastic separator as a triangle can change the direction in which the plastic separator pushes the snap-fit ​​sealing ring, pushing the snap-fit ​​sealing ring towards the annular side groove.

[0019] Optionally, a connecting sealing ring is provided between the intermediate ring and the side ring.

[0020] By adopting the above technical solution, the connection sealing ring can improve the connection stability between the side ring and the middle ring.

[0021] Optionally, a rigid outer ring is provided on the side of the rubber ring near the middle ring.

[0022] By adopting the above technical solution, setting a rigid outer ring can facilitate the smooth movement of the rubber ring within the displacement groove.

[0023] Optionally, the middle ring has a mounting slot on the side near the edge ring, and the edge ring has a mounting block that engages with the mounting slot on the side near the middle ring.

[0024] By adopting the above technical solution, inserting the mounting block into the mounting slot can align the threaded hole on the intermediate ring with the threaded hole on the semi-circular ring.

[0025] Secondly, this application provides an installation method for a fluid pipeline clamping clamp, which adopts the following technical solution. The installation method for this clamp includes the following steps:

[0026] a. Place the rubber ring in the displacement groove, then place the intermediate ring between the two pipe bodies, and insert the end of the pipe body into the intermediate ring so that the separator contacts the rubber ring;

[0027] b. Place the two semicircular rings onto the pipe body and insert the plug into the slot so that the two semicircular rings form a side ring;

[0028] c. Rotate and adjust the side ring to align the mounting block with the mounting slot and make the two toothed belt rings mesh with each other, so that the connecting sealing rings contact the middle ring and the side ring respectively;

[0029] d. Secure the connection between the middle ring and the side ring using connectors.

[0030] By adopting the above technical solution, the side ring is set as two interconnected semicircular rings, which facilitates the fitting of the side ring onto the pipe body and enables rapid installation of the side ring. In addition, inserts and slots are set between the semicircular rings to improve the connection stability between the two semicircular rings.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. When assembling two semicircular rings, first put the two semicircular rings on the outside of the pipe body, combine the two semicircular rings into a side ring, and insert the insert of the inner connecting block into the slot of the outer connecting block to complete the assembly of the side ring. The setting of the insert and slot not only facilitates the quick assembly of the side ring, but also improves the connection stability between the two semicircular rings during the use of the side ring.

[0033] 2. When the pipe body is at a high temperature, the expansion of the pipe body will compress the rubber ring, which in turn will compress the rigid outer ring, causing the rigid outer ring to shift slightly towards the edge ring. This will reduce the impact of the expansion of the pipe body on the intermediate ring. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0041] This application discloses a fluid pipeline clamping clamp. (Refer to...) Figure 1 The fluid pipeline clamping clamp includes an intermediate ring 2 and a side ring 3. There are two side rings 3, which are located on both sides of the intermediate ring 2. The side rings 3 are used to connect the pipeline body 1 and the intermediate ring 2, and the side rings 3 and the intermediate ring 2 are connected by a connector 4.

[0042] Reference Figure 2 Both the intermediate ring 2 and the side ring 3 are circular. A displacement groove 5 is circumferentially formed on the inner wall of the intermediate ring 2 near the side ring 3. The displacement groove 5 has a triangular cross-section, and the closer the displacement groove 5 is to the side ring 3, the greater the distance between the inner wall of the displacement groove 5 and the pipe body 1. A rubber ring 6 is installed inside the displacement groove 5, and the shape of the rubber ring 6 matches the shape of the displacement groove 5. The rubber ring 6 is made of rubber. A rigid outer ring 7 is bonded to the outer side of the rubber ring 6 near the intermediate ring 2. The outer side of the rigid outer ring 7 fits against the displacement groove 5, and the outer side of the rigid outer ring 7 is smooth.

[0043] When installing the clamp, first place the rigid outer ring 7 and the rubber ring 6 in the displacement groove 5, so that the outer side of the rigid outer ring 7 fits against the inner wall of the displacement groove 5. Then, pass the pipe body 1 through the intermediate ring 2, so that the inner ring of the rubber ring 6 fits against the outer side of the pipe body 1. When the pipe body 1 is at a high temperature, it will expand slightly. At this time, the expansion of the pipe body 1 will squeeze the rubber ring 6, and the rubber ring 6 will squeeze the rigid outer ring 7. Since the contact surface between the rigid outer ring 7 and the displacement groove 5 is not perpendicular to the direction of its force, the rigid outer ring 7 can move slightly closer to the edge ring 3. Moreover, since the rubber ring 6 itself has deformation capacity, the impact of the expansion of the pipe body 1 on the intermediate ring 2 is reduced.

[0044] Reference Figure 2 and Figure 3 The inner wall of the side ring 3, near the middle ring 2, has a circumferentially formed an annular groove 8. A snap-fit ​​assembly is installed on the outer side of the pipe body 1, and the snap-fit ​​assembly engages with the annular groove 8. The side ring 3 includes two semicircular rings 9, which can cooperate to form a circular side ring 3. Both semicircular rings 9 can be fitted onto the outer side of the pipe body 1. The opposite ends of the semicircular rings 9 are integrally connected to an inner connecting block 10 and an outer connecting block 11, respectively. The inner connecting block 10 is located at one end of the semicircular ring 9 and near the middle ring 2, while the outer connecting block 11 is located at the other end of the semicircular ring 9 and away from the middle ring 2. When the two semicircular rings 9 are combined to form the side ring 3, the inner connecting block 10 and the outer connecting block 11 of the two semicircular rings 9 can fit together, and the two semicircular rings 9 are also connected by a connector 4. In this embodiment, the connector 4 is a bolt.

[0045] Reference Figure 3 and Figure 4Preferably, the intermediate ring 2 has an installation slot 12 on the side near the edge ring 3. The number of installation slots 12 is set to an even number, and several installation slots 12 are arranged circumferentially on one side of the intermediate ring 2. An installation block 13 is fixed at the middle position of the semicircular ring 9 on the side near the intermediate ring 2, and the installation block 13 is inserted into the installation slot 12. After the two semicircular rings 9 are combined into an edge ring 3, the installation block 13 on the semicircular ring 9 is inserted into the installation slot 12 on the intermediate ring 2 to achieve the initial installation between the edge ring 3 and the intermediate ring 2. It also aligns the threaded hole on the intermediate ring 2 with the threaded hole on the semicircular ring 9, which facilitates the subsequent installation of the connecting piece 4.

[0046] Reference Figure 4 and Figure 5 The outer connecting block 11 has a slot 14 on the side near the inner connecting block 10, and the inner connecting block 10 has a plug 15 fixed on the side near the outer connecting block 11, with the plug 15 engaging with the slot 14. An auxiliary groove 16 is provided at the end of the semi-circular ring 9 near the inner connecting block 10, and an auxiliary component is installed at the end of the semi-circular ring 9 away from the outer connecting block 11. The auxiliary component includes an auxiliary spring 17 and a wedge block 18. The auxiliary spring 17 is located within the auxiliary groove 16, with one end fixedly connected to the bottom of the auxiliary groove 16. The wedge block 18 is fixedly connected to the other end of the auxiliary spring 17 and can slide within the auxiliary groove 16. An auxiliary sliding groove 19 is provided at the end of the outer connecting block 11 away from the semi-circular ring 9, with the wedge block 18 engaging with the auxiliary sliding groove 19, and the inclined surface of the wedge block 18 facing away from the intermediate ring 2. In addition, an extension opening 20 is provided on the outer side of the semicircular ring 9 corresponding to the position of the auxiliary groove 16, and a pull rod 21 that extends out of the outer side of the semicircular ring 9 through the extension opening 20 is fixed on the outer side of the wedge block 18.

[0047] When assembling the two semicircular rings 9, first place the two semicircular rings 9 on the outside of the pipe body 1, one in front of the other. Then pull the lever 21 so that the wedge block 18 is completely inside the auxiliary groove 16, and insert the insert 15 of the inner connecting block 10 into the slot 14 of the outer connecting block 11. Then release the lever 21, and the wedge block 18 is pushed into the auxiliary sliding groove 19 by the auxiliary spring 17, thus completing the assembly of the side ring 3. It should be noted that the arrangement of the auxiliary components, insert 15 and slot 14 not only facilitates the rapid assembly of the side ring 3, but also improves the connection stability between the two semicircular rings 9 during the use of the side ring 3.

[0048] Reference Figure 2The snap-fit ​​assembly includes a snap-fit ​​ring 22 and a snap-fit ​​sealing ring 23. The snap-fit ​​ring 22 is fixedly sleeved on the outside of the pipe body 1. The snap-fit ​​ring 22 is circular with a trapezoidal cross-section. The snap-fit ​​sealing ring 23 is bonded to the side of the snap-fit ​​ring 22 near the intermediate ring 2. In this embodiment, the snap-fit ​​sealing ring 23 is made of rubber and has a certain degree of elasticity. The snap-fit ​​ring 22 and the snap-fit ​​sealing ring 23 are combined to form the snap-fit ​​assembly. After the snap-fit ​​ring 22 and the snap-fit ​​sealing ring 23 are engaged, they can achieve snap-fit ​​engagement with the annular side groove 8. After the side ring 3 and the intermediate ring 2 are fixed, the pipe body 1 and the intermediate ring 2 are fixed by the engagement of the snap-fit ​​assembly and the annular side groove 8.

[0049] It should be noted that several plastic partition plates 24 are fixed on the outer side of the pipe body 1. The plastic partition plates 24 are arranged circumferentially along the outer side of the pipe body 1. The plastic partition plates 24 are located between the snap-fit ​​sealing ring 23 and the rubber ring 6. The cross-section of the plastic partition plates 24 is triangular. In this embodiment, the plastic partition plates 24 are made of plastic and have a certain plasticity and deformation capacity. The sides of the plastic partition plates 24 and the rubber ring 6 that are close to each other are parallel to each other. The further away the plastic partition plates 24 are from the pipe body 1, the shorter the cross-sectional length of the plastic partition plates 24 is. The side of the plastic partition plates 24 that is close to the snap-fit ​​sealing ring 23 is inclined. The snap-fit ​​sealing ring 23 is hollow inside. Several deformation grooves 25 are opened on the side wall of the annular side groove 8 corresponding to the position of the snap-fit ​​sealing ring 23. The deformation grooves 25 are arranged circumferentially along the annular side groove 8.

[0050] When the pipe body 1 expands slightly due to heat, the rubber ring 6 squeezes the plastic separator 24. The plastic separator 24 deforms and squeezes the snap-fit ​​sealing ring 23. Since the snap-fit ​​sealing ring 23 is hollow inside, it has a large deformation capacity, which causes the side of the snap-fit ​​sealing ring 23 to squeeze the side wall of the annular side groove 8. If the deformation of the snap-fit ​​sealing ring 23 is too large, part of the snap-fit ​​sealing ring 23 can extend into the deformation groove 25. This can not only improve the connection stability between the pipe body 1 and the side ring 3, but also reduce the phenomenon of damage to the side ring 3 and the middle ring 2 caused by excessive expansion of the pipe body 1. It should be noted that the rigid outer ring 7 facilitates the smooth movement of the rubber ring 6 within the displacement groove 5, and the plastic separator 24 can, to some extent, prevent the rubber ring 6 from dislodging from the displacement groove 5 under normal circumstances. Furthermore, by setting the plastic separator 24 in a triangular shape and tilting the side of the plastic separator 24 closest to the snap-fit ​​sealing ring 23, the direction in which the plastic separator 24 pushes the snap-fit ​​sealing ring 23 can be changed, pushing the snap-fit ​​sealing ring 23 towards the annular side groove 8, thereby improving the connection stability between the pipe body 1 and the side ring 3.

[0051] Furthermore, a space is reserved between the annular side groove 8 and the snap ring 22, with a circumferential ring in this space. Toothed belt rings 26 are bonded to the side wall of the annular side groove 8 and the outer side of the snap ring 22. The two toothed belt rings 26 mesh with each other, and the teeth on the toothed belt rings 26 are triangular in shape. In this embodiment, the toothed belt rings 26 are made of rubber material and have a certain deformation capacity. When the pipe body 1 is in a low-temperature environment, the pipe body 1 will shrink slightly. Due to the two toothed belt rings 26 and their meshing, the circumferential displacement between the pipe body 1 and the side ring 3 can be reduced. Moreover, the toothed belt rings 26 have a certain deformation capacity, so even at higher temperatures, excessive compression between the snap ring 22 and the side ring 3 is not likely to occur.

[0052] Preferably, a connecting sealing ring 27 is installed between the intermediate ring 2 and the side ring 3, and the connector 4 passes through the connecting sealing ring 27. The connecting sealing ring 27 can improve the connection stability between the side ring 3 and the intermediate ring 2.

[0053] The implementation principle of a fluid pipeline clamping clamp according to an embodiment of this application is as follows: When installing the clamp, first place the rigid outer ring 7 and the rubber ring 6 in the displacement groove 5, so that the outer side of the rigid outer ring 7 is in contact with the inner wall of the displacement groove 5. Then, the pipeline body 1 passes through the intermediate ring 2, so that the inner ring of the rubber ring 6 is in contact with the outer side of the pipeline body 1. Then, assemble the two semi-circular rings 9 into a side ring 3, and insert the mounting block 13 into the mounting slot 12 to achieve the initial installation between the side ring 3 and the intermediate ring 2. Then, fix the side ring 3 and the intermediate ring 2 through the connector 4.

[0054] When the pipe body 1 expands slightly due to heat, the rubber ring 6 compresses the plastic separator 24. The plastic separator 24 deforms and compresses the snap-fit ​​sealing ring 23, causing the side of the snap-fit ​​sealing ring 23 to press against the side wall of the annular groove 8. If the deformation of the snap-fit ​​sealing ring 23 is too large, part of the snap-fit ​​sealing ring 23 can extend into the deformation groove 25. This not only improves the connection stability between the pipe body 1 and the side ring 3, but also reduces the damage to the side ring 3 and the intermediate ring 2 caused by excessive expansion of the pipe body 1. When the pipe body 1 is in a lower temperature environment, the pipe body 1 will shrink slightly. Because two toothed belt rings 26 are provided and the toothed belt rings 26 mesh with each other, the circumferential displacement between the pipe body 1 and the side ring 3 can be reduced.

[0055] This application also discloses an installation method for a fluid pipeline clamping clamp, which includes the following steps:

[0056] a. Place the rigid outer ring 7 and the rubber ring 6 in the displacement groove 5, so that the outer side of the rigid outer ring 7 is in contact with the inner wall of the displacement groove 5, and then pass the pipe body 1 through the intermediate ring 2, so that the inner ring of the rubber ring 6 is in contact with the outer side of the pipe body 1, and the plastic partition 24 is in contact with the rubber ring 6.

[0057] b. Place the two semicircular rings 9 on the outside of the pipe body 1, with the two semicircular rings 9 one in front of the other. Then pull the lever 21 so that the wedge block 18 is completely located in the auxiliary groove 16, and insert the insert block 15 of the inner connecting block 10 into the slot 14 of the outer connecting block 11. Then release the lever 21, and the wedge block 18 is pushed into the auxiliary slide groove 19 by the auxiliary spring 17, so that the two semicircular rings 9 form a side ring 3.

[0058] c. Rotate and adjust the side ring 3 so that the mounting block 13 is aligned with the mounting groove 12 and the two toothed belt rings 26 mesh with each other, so that the connecting sealing ring 27 contacts the middle ring 2 and the side ring 3 respectively, and then make the plastic separator 24 fit with the rubber ring 6.

[0059] d. Finally, the middle ring 2 and the side ring 3 are fixedly connected by the connector 4.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
