Description

Technical Field

[0001] This utility model belongs to the technical field of ship pipeline systems, specifically, it relates to an intelligent anti-corrosion ship pipeline sealing device. Background Technology

[0002] In shipboard piping systems, the sealing devices at pipe joints are crucial components ensuring the stable transmission of media such as fuel oil, cooling seawater, and fresh water. Their connection and sealing performance directly affect the operational reliability of the shipboard piping system and are of great importance to the ship's normal navigation. Currently, flange connections are widely used in shipboard piping connections due to their mature structure and relatively stable sealing performance. This connection method uses bolts to tighten the flanges at the two pipe ends, causing the gasket between the flanges to be compressed and deformed, thereby achieving a sealed connection.

[0003] However, flange connections are secured one by one with multiple bolts, making the installation and disassembly process cumbersome. Furthermore, the pipe length of flange connections is fixed, and when the length does not match due to measurement errors or installation deviations during pipe laying, the connection length cannot be flexibly adjusted, requiring additional cutting or splicing of pipes, which increases the construction difficulty.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0005] To address the cumbersome installation and disassembly process of flange connections, which rely on multiple bolts for individual fastening, and the fixed pipe length of flange connections, which makes length mismatches during pipe laying due to measurement errors or installation deviations impossible to adjust flexibly, necessitating additional pipe cutting or splicing and increasing construction difficulty, the basic concept of this utility model is as follows: An intelligent corrosion-resistant shipboard pipeline sealing device includes a connecting pipe and a sealing pipe. The connecting pipe and the sealing pipe are adjustablely snapped together. Both ends of the sealing pipe are provided with sliding grooves. A connecting seat is slidably installed in the sliding groove. A spring is also provided in the sliding groove. The two ends of the spring abut against the connecting seat and the inner wall of the sliding groove, respectively. The end of the connecting pipe is provided with a locking block that matches the connecting seat. The sealing connection between the connecting pipe and the sealing pipe is achieved through the cooperation of the connecting seat and the locking block. The inner wall of the sealing pipe is provided with a spiral guide plate.

[0006] In a preferred embodiment of this utility model, the number of locking blocks at the end of the connecting pipe is four, and the four locking blocks are evenly spaced along the circumference of the connecting pipe. The connecting seat has a through groove adapted to the locking blocks, and the locking blocks pass through the through groove and connect to the connecting seat.

[0007] In a preferred embodiment of this utility model, the connecting seat has an inclined surface on one side, and the number of inclined surfaces is the same as that of the locking block.

[0008] In a preferred embodiment of this utility model, the connecting seat is further provided with a baffle, which is disposed on one side of the through groove, and the number of baffles is the same as that of the locking block.

[0009] In a preferred embodiment of this utility model, both ends of the sealing tube are provided with guide surfaces. The guide surfaces have a chamfered structure, with one end connected to the edge of the sealing tube port and the other end extending inclinedly into the sealing tube.

[0010] In a preferred embodiment of this utility model, both ends of the sealing tube are provided with mounting grooves, and a sealing gasket is provided in the mounting groove. The sealing gasket is in contact with the inner wall of the connecting tube, and the material of the sealing gasket is fluororubber.

[0011] Compared with the prior art, the present invention has the following advantages: This utility model achieves connection through the cooperation of the locking block and the connecting seat, simplifying the installation and maintenance process. By utilizing the sliding cooperation between the sliding groove inside the sealing pipe and the connecting seat, the locking depth of the connecting pipe can be flexibly adjusted according to the actual length of the pipeline to accommodate length deviations. At the same time, the adjustment of the locking depth can simultaneously change the degree of compression of the sealing gasket by the connecting pipe, thereby adjusting the degree of sealing.

[0012] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0016] like Figures 1 to 3As shown, the intelligent anti-corrosion ship pipeline sealing device includes a connecting pipe 1 and a sealing pipe 2. The connecting pipe 1 and the sealing pipe 2 are adjustablely snapped together. Both ends of the sealing pipe 2 are provided with sliding grooves 21. A connecting seat 22 is slidably installed in the sliding groove 21. A spring 3 is also provided in the sliding groove 21. The two ends of the spring 3 abut against the inner wall of the connecting seat 22 and the sliding groove 21, respectively. The end of the connecting pipe 1 is provided with a locking block 11 that matches the connecting seat 22. The sealing connection between the connecting pipe 1 and the sealing pipe 2 is achieved through the cooperation of the connecting seat 22 and the locking block 11. The inner wall of the sealing pipe 2 is provided with a spiral guide plate 5. In this configuration, the connecting pipe 1 cooperates with the connecting seat 22 on the sealing pipe 2 through the locking block 11 at its end. Combined with the elastic force of the spring 3 in the sliding groove 21, the two are adjustablely snapped together, ensuring connection stability and adapting to length deviations during installation. The spiral guide plate 5 on the inner wall of the sealing pipe 2 can guide the orderly flow of the medium in the pipe and reduce flow resistance.

[0017] like Figures 1 to 3 As shown in the specific embodiment, there are four locking blocks 11 at the end of the connecting pipe 1. The four locking blocks 11 are evenly spaced along the circumference of the connecting pipe 1. The connecting seat 22 has through slots 23 that are adapted to the locking blocks 11. The locking blocks 11 pass through the through slots 23 and connect to the connecting seat 22. In this configuration, the four locking blocks 11 evenly distributed along the circumference of the connecting pipe 1 pass through the corresponding through slots 23 on the connecting seat 22, making the force on the connecting pipe 1 and the connecting seat 22 more balanced, avoiding excessive local stress that could cause the connection to loosen, and improving the overall reliability of the connection.

[0018] like Figures 1 to 3 As shown, further, one side of the connecting seat 22 is provided with an inclined surface 25, the number of which is the same as the number of locking blocks 11. In this configuration, the inclined surfaces 25 on the connecting seat 22, which are the same number as the locking blocks 11, contact the corresponding locking blocks 11 when the connecting seat 22 rotates. Through the guiding effect of the inclined surfaces 25, the locking blocks 11 gradually fit and tighten as the connecting seat 22 rotates.

[0019] like Figures 1 to 3 As shown, the connecting seat 22 is further provided with a baffle 24, which is located on one side of the through groove 23. The number of baffles 24 is the same as the number of locking blocks 11. In this configuration, the number of baffles 24 on one side of the through groove 23 corresponds to the number of locking blocks 11. When the connecting seat 22 rotates to the position where the locking block 11 is fully engaged with the inclined surface 25, the baffle 24 can prevent the connecting seat 22 from continuing to rotate, thus preventing the locking block 11 from disengaging from the through groove 23.

[0020] like Figures 1 to 3As shown, furthermore, both ends of the sealing tube 2 are provided with guide surfaces 27. The guide surfaces 27 have a chamfered structure, with one end connected to the edge of the port of the sealing tube 2 and the other end extending inclinedly into the sealing tube 2. In this configuration, the chamfered guide surfaces 27 at both ends of the sealing tube 2 are inclined inward from the edge of the port, which can smoothly guide the medium transported by the connecting tube 1 into the sealing tube 2 and avoid the medium from stagnating at the connection.

[0021] like Figures 1 to 3 As shown, furthermore, both ends of the sealing tube 2 are provided with mounting grooves 26, and a sealing gasket 4 is provided in the mounting groove 26. The sealing gasket 4 is in close contact with the inner wall of the connecting tube 1, and the material of the sealing gasket 4 is fluororubber. In this configuration, the sealing gasket 4 is in close contact with the inner wall of the connecting tube 1, which improves the corrosion resistance and sealing reliability of the device.

[0022] The implementation principle of the intelligent anti-corrosion ship pipeline sealing device in this embodiment is as follows: When assembling the connecting pipe 1 and the sealing pipe 2, first align the end of the connecting pipe 1 with the end of the sealing pipe 2, so that the four locking blocks 11 at the end of the connecting pipe 1 are respectively aligned with the through grooves 23 on the connecting seats 22 at both ends of the sealing pipe 2. Then push the connecting pipe 1 so that the locking blocks 11 pass through the through grooves 23 and extend into the inside of the connecting seat 22. During this process, the connecting seat 22 will slide along the sliding groove 21 on the sealing pipe 2 under the pushing force of the connecting pipe 1 and squeeze the spring 3 in the sliding groove 21, so that the spring 3 is in a compressed state.

[0023] After the locking block 11 has completely passed through the through groove 23, rotate the connecting seat 22. The inclined surface 25 on one side of the connecting seat 22 will gradually come into contact with the locking block 11. As the connecting seat 22 continues to rotate, the locking block 11 slides along the inclined surface 25 until the inclined surface 25 and the locking block 11 are tightly fitted together, thereby achieving the locking and fixing of the connecting tube 1 and the sealing tube 2. When the connecting seat 22 rotates to the preset position, the baffle 24 on the side of the through groove 23 on the connecting seat 22 will abut against the end of the sealing tube 2, restricting the connecting seat 22 from continuing to rotate, preventing the locking block 11 from disengaging from the connecting seat 22, and ensuring the stability of the connection.

[0024] During the operation of the device, the sealing gaskets 4 in the mounting grooves 26 at both ends of the sealing pipe 2 are tightly fitted with the inner wall of the connecting pipe 1 to form a sealing structure and prevent leakage of the medium in the pipeline. The guide surfaces 27 at both ends of the sealing pipe 2 are chamfered, with one end connected to the edge of the sealing pipe 2 port and the other end extending inclinedly into the sealing pipe 2. This can smoothly guide the medium in the connecting pipe 1 into the sealing pipe 2. The spiral guide plate 5 on the inner wall of the sealing pipe 2 can further guide the medium to flow in the spiral direction, reduce turbulence during the medium flow process, and improve the stability of the conveying.
