[0002] A high-pressure pipeline of a ship refers to a pipeline system used for transmitting high-pressure fluids or gases on a ship. In order to ensure the airtightness and watertightness of the pipeline system, prevent fluid leakage, and also prevent external substances from entering the system, sealing components are often used at the interfaces of high-pressure pipelines of ships, so that they can not only be connected to other pipelines or equipment, but also achieve a sealing effect. Currently, flanges are mostly used.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Please refer to Figures 1 - 7 , a sealing member for a ship's high-pressure pipeline, including a fixed flange 2 installed at one end of the pipe body 1 and a sealing flange 3 located on one side of the fixed flange 2. A plurality of connection ports 301 are respectively penetrated on the surfaces of the fixed flange 2 and the sealing flange 3. The inner walls of the plurality of connection ports 301 of the fixed flange 2 are fixedly connected with connecting pipes 6. One end of the connecting pipe 6 is slidably connected with the inner wall of the connection port 301 of the sealing flange 3. The other end of the connecting pipe 6 is connected with a clamping component. A plurality of card slots 201 are respectively opened on the inner walls of the plurality of connection ports 301 of the fixed flange 2. One end of the clamping component away from the connecting pipe 6 is connected with the inner walls of the plurality of card slots 201. A plurality of through holes 202 are respectively penetrated on one side of the plurality of card slots 201 close to the pipe body 1. A plurality of limiting components are respectively connected with the inner walls of the plurality of card slots 201. The other ends of the plurality of limiting components respectively penetrate through the plurality of through holes 202. A plurality of locking bolts 4 are respectively threadedly connected with the inner walls of the plurality of connecting pipes 6. The screw rods of the plurality of locking bolts 4 respectively penetrate through the plurality of clamping components and are respectively connected with locking components. A plurality of limiting components in the same connection port 301 are all located inside the locking components.

[0023] As Figures 1 to 7 shown, when the sealing member for a ship's high-pressure pipeline in the present utility model needs to dock the sealing flange 3 with the fixed flange 2, only need to align the plurality of connection ports 301 of the sealing flange 3 and insert them into the connecting pipes 6, then the fixed flange 2 and the sealing flange 3 can be directly aligned and connected; then, after the locking bolts 4 pass through the connecting pipes 6 and the clamping components and are connected with one end of the limiting components located outside the fixed flange 2, the connection stability between the fixed flange 2 and the sealing flange 3 can be increased, and the probability of loosening can be reduced.

[0024] AsFigure 6 and Figure 7 As shown in Figure 7 , the clamping component includes an inclined block 8 and a clamping plate 9. One end of the inclined block 8 with a larger diameter is fixedly connected to one end of the connecting pipe 6 away from the sealing flange 3, one end of the inclined block 8 with a smaller diameter is fixedly connected to the inner end of the clamping plate 9, and the outer end of the clamping plate 9 is slidably connected to the inner wall of the clamping groove 201.

[0025] More specifically, when the locking bolt 4 does not pass through the clamping component, at this time, the inclined block 8 presents a "conical" shape, with one end large and one end small.

[0026] When the locking bolt 4 is inserted from the connection port 301 of the sealing flange 3, when the locking bolt 4 abuts against the inner wall of the inclined block 8, the inclined block 8 can be pushed outwards. While the inclined block 8 is being pushed outwards, the clamping plate 9 will be inserted into the clamping groove 201 until the locking bolt 4 completely passes through the inside of the inclined block 8. At this time, the inclined block 8 and the clamping plate 9 will also be stuck in the clamping groove 201 for positioning.

[0027] After the locking bolt 4 penetrates and fixes the flange 2, the locking component is used to lock the locking bolt 4 and several clamping components simultaneously, thereby further increasing the connection between the fixed flange 2 and the sealing flange 3.

[0028] As Figure 6 and Figure 7 shown, the limiting component includes a support rod 7 and a clamping strip 11. One end of the support rod 7 is fixedly connected to the inner wall of the clamping groove 201, the other end of the support rod 7 penetrates through the through hole 202 and is fixedly connected to one end of the clamping strip 11, and the other end of the clamping strip 11 is located inside the locking component. A plurality of screw ports 1101 are formed on the outer wall of the clamping strip 11, and all the screw ports 1101 are matched with the locking component.

[0029] More specifically, under normal circumstances, the clamping strip 11 is located outside the fixed flange 2. When the locking component needs to be limited, the locking component will move along a plurality of screw ports 1101 on the outside of the clamping strip 11 until the fixed flange 2 and the sealing flange 3 are tightly squeezed and sealed. At this time, due to the limitation of the locking component and the screw ports 1101, the connection between the fixed flange 2 and the sealing flange 3 can also be increased.

[0030] As Figure 6 and Figure 7 shown, the locking component includes a nut 5, an inner tube 12 and a screw ring 10. The inner side of the nut 5 is fixedly connected to one end of the inner tube 12, and the inner side of the nut 5 is also fixedly connected to the outer wall of the screw ring 10. The screw ring 10 is located between the nut 5 and the inner tube 12. The inner wall of the inner tube 12 is threadedly connected to the outer wall of the locking bolt 4. The outer wall of the screw ring 10 is slidably connected to the inner wall of a plurality of screw ports 1101. One side of the nut 5 and the inner tube 12 abuts against the side wall of the fixed flange 2.

[0031] More specifically, when it is necessary to limit the locking bolt 4 and the screw thread 1101, just align the inner tube 12 with the locking bolt 4, and then rotate the nut 5. As the nut 5 moves, the inner tube 12 will move along the outside of the locking bolt 4. At the same time, the screw ring 10 will move along the screw thread 1101. When the inner tube 12 is tightly pressed against the surface of the fixed flange 2, in addition to its own limit, there is an additional limit between the screw ring 10 and the screw thread 1101, which makes the connection between the fixed flange 2 and the sealing flange 3 better, and thus the sealing effect is better.

[0032] As Figure 6 and Figure 7 shown, a plurality of bayonet openings 901 are formed through the outside of the clamping plate 9, and the outer wall of the support rod 7 is slidably connected to the inner wall of the bayonet openings 901.

[0033] More specifically, by providing the bayonet openings 901, it is possible to prevent the clamping plate 9 from colliding with the support rod 7 after the clamping plate 9 is inserted into the card slot 201.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
