Description

Technical Field

[0001] This application belongs to the field of shipbuilding technology, specifically relating to a pipeline sealing device. Background Technology

[0002] Pipeline tightness testing is a crucial step in ensuring the normal operation and safe use of pipeline systems. It involves using specific test media (gas or water) and testing methods to detect any leaks within the pipeline. Before the test, only one pressurization port is left open; all other ports and joints are completely sealed. Therefore, sealing these joints is an important task during the test preparation phase.

[0003] To ensure the sealing of each joint, a plug corresponding to the pipe diameter is fabricated. This method requires threading the joint and then screwing the plug into the pipe, or directly welding the joint securely with a sealing plate. Therefore, sealing the joints involves a large workload and is difficult to construct. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a pipe sealing device, which aims to at least partially solve the technical problems of large workload and high construction difficulty in sealing interfaces.

[0005] The technical solution of this utility model is as follows:

[0006] A pipe sealing device is provided, wherein the pipe has an interface, and the pipe sealing device includes: a collar fitted over the outside of the pipe; a plurality of locking members passing through the collar and abutting against the outer wall of the pipe; a sealing plate abutting against the end of the pipe for sealing the interface; and a plurality of connecting members passing through the sealing plate and detachably connected to the collar.

[0007] In some embodiments, the collar includes: a kit fitted over the outside of the pipe; a plurality of mounting members disposed outside the kit, wherein each mounting member corresponds to a plurality of connecting members and the mounting members are connected to the corresponding connecting members; wherein a plurality of locking members pass through the kit and abut against the outer wall of the pipe.

[0008] In some implementations, the kit has multiple mounting holes, each corresponding to a locking element. The locking element passes through the corresponding mounting hole and abuts against the outer wall of the pipe; wherein the locking element is threaded to the wall of the mounting hole.

[0009] In some implementations, the mounting holes are evenly spaced at equal angles.

[0010] In some implementations, the locking element is located between two adjacent mounting elements.

[0011] In some implementations, multiple mounting components are evenly spaced at equal angles.

[0012] In some embodiments, the mounting member has a connection hole, and the connector is detachably threaded to the wall of the connection hole.

[0013] In some embodiments, the connector includes: a limiting part; and a connecting part, one end of which is connected to the limiting part, and the other end of which passes through the sealing plate and is connected to the mounting part.

[0014] In some embodiments, the pipe sealing device further includes a seal located between the sealing plate and the end of the pipe.

[0015] In some implementations, the sealing plate has multiple mounting slots, and the sealing element is disposed in the mounting slots.

[0016] The beneficial effects of this utility model include at least the following:

[0017] Because the collar is fitted over the pipe, multiple locking elements pass through the collar and abut against the outer wall of the pipe, and the sealing plate abuts against the end of the pipe to seal the joint, and multiple connectors pass through the sealing plate and are detachably connected to the collar, when conducting a pipe tightness test, the collar is fitted over the pipe, multiple locking elements pass through the collar and abut against the outer wall of the pipe to secure the collar to the outside of the pipe, the sealing plate abuts against the end of the pipe to seal the joint, and then multiple connectors pass through the sealing plate and connect to the collar to achieve the fixed installation of the sealing plate. This allows the sealing plate to completely seal the joint, enabling the pipe tightness test to be conducted. There is no need to thread the pipe joint or weld it, the sealing workload is small, the construction difficulty is low, and the work efficiency is improved.

[0018] During the pipe tightness test, multiple connectors can be removed from the collar, allowing the sealing plate to be removed from the pipe joint. Then, the locking mechanism can be operated to separate it from the outer wall of the pipe, allowing the collar to be removed from the pipe and ensuring that the pipe can be used normally.

[0032] This application is described below with reference to the accompanying drawings and specific embodiments:

[0033] The high-purity aluminum cleaning device provided in this embodiment aims to solve, to some extent, the technical problems of large workload and high construction difficulty in sealing interfaces.

[0034] Figure 1 This is a schematic diagram of the installation of the pipe sealing device according to some embodiments; Figure 2 for Figure 1 Exploded view of the pipeline sealing device. (Combined with...) Figure 1 and Figure 2 The pipe 10 has an interface. In this embodiment, the pipe 10 sealing device includes: a collar 20, locking elements 30, a sealing plate 40, and connecting elements 50. The collar 20 is fitted over the pipe 10. Multiple locking elements 30 pass through the collar 20 and abut against the outer wall of the pipe 10. The sealing plate 40 abuts against the end of the pipe 10 to seal the interface. Multiple connecting elements 50 pass through the sealing plate 40 and are detachably connected to the collar 20.

[0035] The connector 50 can be a bolt or a screw.

[0036] The locking element 30 can be a bolt or a screw.

[0037] Since the collar 20 is fitted over the pipe 10, multiple locking elements 30 pass through the collar 20 and abut against the outer wall of the pipe 10, and the sealing plate 40 abuts against the end of the pipe 10 to seal the interface, and multiple connecting elements 50 pass through the sealing plate 40 and are detachably connected to the collar 20, when a pipe 10 tightness test is to be performed, the collar 20 is fitted over the pipe 10, multiple locking elements 30 pass through the collar 20 and abut against the outer wall of the pipe 10 to fasten the collar 20 to the outside of the pipe 10, the sealing plate 40 abuts against the end of the pipe 10 to seal the interface, and then multiple connecting elements 50 pass through the sealing plate 40 and connect to the collar 20 to achieve the fixed installation of the sealing plate 40. This allows the sealing plate 40 to completely seal the interface, and the pipe 10 tightness test can then be performed. There is no need to thread the interface of the pipe 10 or weld it, the sealing workload is small, the construction difficulty is low, and the work efficiency is improved.

[0038] During the leak test of pipe 10, multiple connectors 50 can be removed from collar 20, and the sealing plate 40 can be removed from the interface of pipe 10. Then, the locking member 30 is operated to separate the locking member 30 from the outer wall of pipe 10, and the collar 20 can be removed from pipe 10 to ensure that pipe 10 can be used normally.

[0039] Combination Figure 1 and Figure 2In some embodiments, to allow the collar 20 to be fitted onto the outside of the pipe 10 and to connect the collar 20 to the connector 50, the collar 20 includes a fitting 21 and mounting members 22. The fitting 21 is fitted onto the outside of the pipe 10. Multiple mounting members 22 are disposed outside the fitting 21, and each mounting member 22 corresponds one-to-one with a corresponding connector 50, with the mounting member 22 connected to the corresponding connector 50. Multiple locking members 30 pass through the fitting 21 and abut against the outer wall of the pipe 10. The mounting member 22 can be a nut.

[0040] When conducting a leak test on pipe 10, the kit 21 is fitted over pipe 10, and multiple locking pieces 30 are inserted through the kit 21 and abut against the outer wall of pipe 10 to secure the kit 21 to the outside of pipe 10. The sealing plate 40 abuts against the end of pipe 10 to seal the interface. Then, multiple connectors 50 are inserted through the sealing plate 40 and connected to the mounting piece 22 to achieve fixed installation of the sealing plate 40. This allows the sealing plate 40 to completely seal the interface, enabling the leak test on pipe 10 to be conducted. No threading or welding is required at the interface of pipe 10, resulting in less sealing work, lower construction difficulty, and improved work efficiency.

[0041] During the pipe 10 tightness test, multiple connectors 50 can be removed from the mounting piece 22, and the sealing plate 40 can be removed from the interface of the pipe 10. Then, the locking piece 30 is operated to separate the locking piece 30 from the outer wall of the pipe 10, and the kit 21 can be removed from the pipe 10 to ensure that the pipe 10 can be used normally.

[0042] In some embodiments, the inner diameter of the kit 21 is larger than the outer diameter of the pipe 10, so that the kit 21 can be adapted to pipes 10 of different diameters, has a certain degree of versatility, and reduces the storage capacity and cleaning and maintenance work in the warehouse.

[0043] In some embodiments, the area of ​​the sealing plate 40 is larger than the area of ​​the interface, so that the sealing plate 40 can be adapted to pipes 10 of different diameters, has a certain degree of versatility, and reduces the storage capacity and cleaning and maintenance work in the warehouse.

[0044] Combination Figure 2 In some embodiments, to enable the locking member 30 to perform locking and unlocking actions, the kit 21 has multiple mounting holes 23, each corresponding to a locking member 30. The locking member 30 passes through the corresponding mounting hole 23 and abuts against the outer wall of the pipe 10. The locking member 30 is threadedly connected to the wall of the mounting hole 23.

[0045] In some embodiments, when the kit 21 is to be fastened to the outer wall of the pipe 10, the locking member 30 passes through the corresponding mounting hole 23, and the locking member 30 is rotated so that the locking member 30 is threadedly connected to the wall of the mounting hole 23 until the locking member 30 abuts against the outer wall of the pipe 10, thus locking the kit 31 outside the pipe 10. When it is necessary to remove the kit 31 from the outside of the pipe 10, the locking member 30 is rotated so that the locking member 30 is separated from the wall of the mounting hole 23, thereby removing the kit 31.

[0046] In some embodiments, in order to ensure the stability of the kit 21 when it is fitted outside the pipe 10, multiple mounting holes 23 are evenly spaced at equal angles, which can make the kit 21 bear force evenly and ensure the stability of the installation of the kit 21.

[0047] In some embodiments, in order to ensure that the locking action of the locking member 30 is performed normally, the locking member 30 is located between two adjacent mounting members 22 to avoid the mounting members 22 interfering with the locking action of the locking member 30, and to provide sufficient space for the locking action of the locking member 30 to facilitate operation.

[0048] In some embodiments, in order to ensure the stability of the connection between the kit 21 and the sealing plate 40, multiple mounting parts 22 are evenly spaced at equal angles, which can make the sealing plate 40 bear force evenly and ensure the stability of the installation of the sealing plate 40.

[0049] Combination Figure 2 In some embodiments, in order to enable the connector 50 to be detachably connected to the mounting member 22, the mounting member 22 is provided with a connection hole 24, and the connector 50 is threadedly connected to the wall of the connection hole 24.

[0050] When the sealing plate 40 is to be used to seal the interface of the pipe 10, the connector 50 is rotated, and the connector 50 is threaded into the wall of the connecting hole 24 to install the sealing plate 40. When the sealing plate 40 is to be removed, the connector 50 is rotated, and the connector 50 is separated from the connecting hole 24 to remove the sealing plate 40.

[0051] Combination Figure 1 and Figure 2 In some embodiments, to enable the connector 50 to be detachably connected to the mounting member 22, the connector 50 includes a limiting portion 51 and a connecting portion 52. One end of the connecting portion 52 is connected to the limiting portion 51, and the other end passes through the sealing plate 40 and is connected to the mounting member 22. When the connector 50 is a bolt or screw, the limiting portion 51 can be a nut, and the connecting portion 52 can be a screw.

[0052] When the sealing plate 40 is to be used to seal the interface of the pipe 10, the connecting part 52 is rotated, and the connecting part 52 is threadedly connected to the wall of the connecting hole 24 to install the sealing plate 40. When the connecting part 52 reaches its limit position, the limiting part 51 abuts against the sealing plate 40 to limit the movement of the connecting part 52 and prevent excessive movement. When the sealing plate 40 is to be removed, the connecting part 52 is rotated, and the connecting part 52 separates from the connecting hole 24 to remove the sealing plate 40.

[0053] In some embodiments, to ensure the sealing performance of the sealing plate 40 at the pipe 10 interface, the pipe 10 sealing device further includes a sealing element. The sealing element is located between the sealing plate 40 and the end of the pipe 10, and abuts against the pipe wall at the end of the pipe 10. The sealing element 10 can be used to create a gap between the pipe 10 and the sealing plate 40, thereby ensuring a sealing effect and allowing the pipe 10's tightness test to proceed normally. The sealing element can be made of rubber.

[0054] In some embodiments, the seal may be a sealing ring, the inner diameter of which matches the inner diameter of the pipe 10, and the outer diameter of which matches the outer diameter of the pipe 10.

[0055] In some embodiments, to facilitate the installation of the seal, the sealing plate 40 is provided with multiple mounting grooves, the seal is disposed in the mounting groove, the mounting groove accommodates the sealing ring, and the groove wall of the mounting groove can limit the seal, so as to prevent the seal from falling off when the sealing plate 40 seals the interface of the pipe 10, so as to facilitate the sealing of the seal.

[0056] Multiple mounting slots are annular and concentrically arranged. The diameter of the mounting slots gradually increases from the center of the sealing plate 40 to the edge of the sealing plate 40.

[0057] Based on the inner diameter and outer diameter of pipe 10, select a seal that matches the inner diameter and outer diameter of pipe 10, and place the seal into a mounting groove that matches the size of the seal in one of the multiple mounting grooves to facilitate the installation of the seal.
