Description

Technical Field

[0001] This utility model relates to the field of ship hull fireproof sealing technology, and in particular to a ship pipeline fireproof sealing penetration device. Background Technology

[0002] On ships, various pipelines are ubiquitous, connecting different compartments or areas to ensure that gas and liquid can flow in all parts of the hull. For example, fuel is transported from the storage tank to the engine room, and cooling water pipelines connect the cooling system to various equipment that needs to be cooled.

[0003] Various piping systems on board ships often need to pass through bulkheads and decks. If these penetration points are not effectively fireproofed and sealed, they may become channels for the spread of fire in the event of a fire, thus posing a serious threat to the safety of the ship. Therefore, we propose a fireproof and sealing penetration device for marine piping. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a fireproof sealing penetration device for marine pipelines.

[0005] This utility model is achieved by the following technical solution: a fireproof sealing penetration device for marine pipelines, including a bulkhead, a steel sleeve fixedly connected to the inner wall of the bulkhead, a pipeline inside the steel sleeve, flame-retardant expanding fireproof sealant at both ends of the steel sleeve, a flame-retardant expanding fireproof tape wrapped around the surface of the pipeline, and a sealing moisture-proof tape at both ends of the flame-retardant expanding fireproof tape.

[0006] Through the above technical solution, when a ship encounters a fire, the flame-retardant intumescent fireproof sealant will expand when heated, thereby filling the connection between the steel sleeve and the pipeline to form a tight seal, preventing flames and smoke from spreading through the gaps between the steel sleeve and the pipeline. In addition, in the event of a fire, the flame-retardant intumescent fireproof strip will also expand when heated, filling the gaps between the steel sleeve and the pipeline, further enhancing the fireproof performance, preventing the spread of fire, and thus improving the reliability during use.

[0007] As a further improvement to the above solution, the surface of the pipeline is fitted with the inner wall of the flame-retardant intumescent fireproof sealant.

[0008] With the above technical solution, since the flame-retardant intumescent fireproof sealant is applied to the surface of the pipeline, it is easy to replace the flame-retardant intumescent fireproof sealant in the future, thus improving the convenience of maintenance.

[0009] As a further improvement to the above solution, the surface of the flame-retardant intumescent fireproof sealant is in contact with the inner wall of the steel sleeve.

[0010] The above technical solution provides mechanical protection through steel sleeves, preventing pipelines from being damaged in fire or other severe conditions and ensuring the normal function of the pipelines.

[0011] As a further improvement to the above solution, the surface of the flame-retardant intumescent fireproof strip is in contact with the inner wall of the steel sleeve.

[0012] Through the above technical solutions, the flame-inflatable fireproof sealant and the flame-retardant inflatable fireproof strip can expand rapidly in the event of a fire, forming an effective fire barrier to prevent the spread of fire and improve the safety of the ship.

[0013] As a further improvement to the above solution, the flame-retardant intumescent fireproof strip is located in the middle of the pipeline.

[0014] As a further improvement to the above solution, the inner wall of the sealing moisture-proof strip is fitted onto the surface of the pipeline.

[0015] The above technical solution allows the sealing moisture-proof tape to be fitted onto the surface of the pipeline, facilitating its replacement and subsequent maintenance.

[0016] As a further improvement to the above solution, the inner wall of the sealing moisture-proof strip is fitted onto the surface of the pipeline.

[0017] The above technical solution prevents moisture from entering the interior of the steel casing by using a sealed moisture-proof tape, protects the flame-retardant expansion fireproof tape from moisture, extends its service life, and ensures long-term stability of its fireproof performance.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This invention utilizes a flame-retardant intumescent fireproof sealant and a flame-retardant intumescent fireproof strip. Specifically, when a ship encounters a fire, the flame-retardant intumescent fireproof sealant expands upon heating, filling the connection between the steel sleeve and the pipeline to form a tight seal. This prevents flames and smoke from spreading through the gaps between the steel sleeve and the pipeline. Furthermore, in the event of a fire, the flame-retardant intumescent fireproof strip also expands upon heating, filling the gaps between the steel sleeve and the pipeline, further enhancing fire resistance and preventing the spread of fire, thereby improving reliability during use.

[0020] This utility model improves the sealing effect between the steel sleeve and the pipeline by setting a sealing moisture-proof strip, thereby preventing the flame-retardant intumescent fireproof strip from being in a humid environment for a long time, protecting the flame-retardant intumescent fireproof strip from the effects of moisture, thus extending the service life of the flame-retardant intumescent fireproof strip and ensuring the long-term stability of its fire-resistant performance.

[0028] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] Example:

[0030] Please combine Figure 1-5 This embodiment of a marine pipeline fireproof sealing penetration device includes a bulkhead 1, a steel sleeve 2 fixedly connected to the inner wall of the bulkhead 1, a pipeline 3 disposed inside the steel sleeve 2, flame-retardant expanding fireproof sealant 4 disposed at both ends of the steel sleeve 2, a flame-retardant expanding fireproof strip 5 wrapped around the surface of the pipeline 3, and sealing moisture-proof strips 6 disposed at both ends of the flame-retardant expanding fireproof strip 5. When the ship encounters a fire, the flame-retardant expanding fireproof sealant 4 will expand when heated, thereby filling the connection between the steel sleeve 2 and the pipeline 3 to form a tight seal, preventing flames and smoke from spreading through the gap between the steel sleeve 2 and the pipeline 3. In the event of a fire, the flame-retardant expanding fireproof strip 5 will also expand when heated, filling the gap between the steel sleeve 2 and the pipeline 3, further enhancing the fireproof performance and preventing the spread of fire, thereby improving the reliability during use.

[0031] The surface of pipe 3 is fitted with the inner wall of flame-retardant expanding fireproof sealant 4. Because flame-retardant expanding fireproof sealant 4 is fitted with pipe 3, it is easy to quickly disassemble and replace it, which improves the convenience of subsequent maintenance.

[0032] The surface of the flame-retardant intumescent fireproof sealant 4 is in contact with the inner wall of the steel sleeve 2.

[0033] The surface of the flame-retardant intumescent fireproof strip 5 is in contact with the inner wall of the steel sleeve 2.

[0034] The flame-retardant intumescent fireproof strip 5 is located in the middle of the pipe 3.

[0035] The inner wall of the sealing moisture-proof strip 6 is fitted onto the surface of the pipe 3. The sealing moisture-proof strip 6 improves the sealing effect between the steel sleeve 2 and the pipe 3, prevents the flame-retardant inflatable fireproof strip 5 from being in a humid environment for a long time, protects the flame-retardant inflatable fireproof strip 5 from the effects of moisture, thereby extending the service life of the flame-retardant inflatable fireproof strip 5 and ensuring the long-term stability of fire resistance performance.

[0036] The surface of the sealing moisture-proof strip 6 is in contact with the inner wall of the steel sleeve 2.

[0037] The implementation principle of the marine pipeline fireproof sealing penetration device in this application embodiment is as follows: When the ship encounters a fire, the flame-retardant intumescent fireproof sealant 4 will expand when heated, thereby filling the connection between the steel sleeve 2 and the pipeline 3 to form a tight seal, preventing flames and smoke from spreading through the gap between the steel sleeve 2 and the pipeline 3. In the event of a fire, the flame-retardant intumescent fireproof strip 5 will also expand when heated, filling the gap between the steel sleeve 2 and the pipeline 3, further enhancing the fireproof performance and preventing the spread of fire, thereby improving the reliability during use. By sealing the moisture-proof strip 6, the sealing effect between the steel sleeve 2 and the pipeline 3 is improved, avoiding the flame-retardant intumescent fireproof strip 5 from being in a humid environment for a long time, protecting the flame-retardant intumescent fireproof strip 5 from the effects of moisture, thereby extending the service life of the flame-retardant intumescent fireproof strip 5 and ensuring the long-term stability of the fireproof performance.
