[0002] In enclosed spaces such as ships or aircraft, pipes are often run through bulkheads or decks to ensure the flow of gas and liquid in various areas of the hull. In the event of a fire, the fire and smoke can spread rapidly, endangering personnel safety and the integrity of equipment. Therefore, sealing devices are needed to seal the gaps between the bulkheads and the pipes.

[0003] Current bulkhead fireproof penetration devices are prone to aging and wear of the packing material after long-term use, requiring regular replacement. Otherwise, the sealing effect of the device will be affected. However, most sealing devices are often integrated structures, which are inconvenient to disassemble and assemble. It is difficult to disassemble and assemble without moving the pipeline, which may damage the penetration pipeline. Professional personnel are required to operate them, and the subsequent maintenance and replacement of the packing material are also very troublesome.

[0004] Therefore, in view of the inconvenience of disassembling and assembling existing bulkhead fireproof penetration devices, which affects subsequent maintenance, a bulkhead fireproof penetration sealing device can be designed. By adopting a split disassembly and assembly method, the disassembly and assembly operation steps of the sealing structure can be simplified, subsequent maintenance operations can be carried out conveniently, the packing replacement steps can be optimized, the sealing performance of the device can be ensured, the service life of the device can be extended, and thus the practical value of the device can be effectively enhanced.

[0028] When installing the sealing device, the through-hole pipe 3 is passed through the inlet pipe 2, so that the through-hole pipe 3 passes through the bulkhead body 1. The first expansion layer 4 is filled between the through-hole pipe 3 and the inlet pipe 2. Then, the two sets of sealing rings 6 are sequentially installed into the first mounting groove 5, so that the first threaded hole 601 is aligned with the first threaded groove 602. At the same time, the first bolt 603 is turned into the first threaded hole 601. The first bolt 603 is continuously rotated so that one end is turned into the first threaded groove 602. The two sets of sealing rings 6 are combined to seal and lock the two ends of the first expansion layer 4.

[0029] Subsequently, the two sets of stop plates 8 are inserted into the second mounting groove 7 in sequence.

[0031] When exposed to high temperatures, the first expansion layer 4 and the second expansion layer 10 expand under high temperatures, filling the gaps and preventing flames and smoke from passing through. At the same time, the sealing ring 11 and the sealing ring 6 can block high temperatures from passing through the bulkhead body 1.

[0032] When removing the sealing device, turn out the third bolt 1107 in sequence, remove the sealing rings 11 at both ends of the inlet pipe 2 in sequence, remove the second expansion layer 10 for replacement, then turn out the second bolt 905 in sequence, remove the mounting plate 9 and stop plate 8 on one side of the sealing ring 6 in sequence, then turn out the first bolt 603 to remove the two sets of sealing rings 6, remove the first expansion layer 4 for replacement, and carry out routine maintenance work.

[0033] Through the above steps, the installation position of the through-tube pipe 3 is determined by setting the inlet pipe 2, so that the through-tube pipe 3 penetrates the main body of the bulkhead 1. The installation position of the sealing ring 6 is determined by the first mounting groove 5. The sealing ring 6 is installed on both ends of the inner side of the inlet pipe 2 by the first mounting assembly. The sealing ring 6 seals and protects the first expansion layer 4 inside. The stop plate 8 is fixedly connected by the mounting plate 9. The installation position of the stop plate 8 is determined by the second mounting groove 7. The position of the stop plate 8 is locked by the stop assembly. The stop plate 8 increases the friction of the through-tube pipe 3 and prevents the position of the through-tube pipe 3 from shaking or shifting. The sealing ring 11 is installed and fixed by the second mounting assembly. The sealing ring 11 seals both ends of the inlet pipe 2 and seals and protects the second expansion layer 10 inside. The first expansion layer 4 and the second expansion layer 10 expand at high temperature, filling the gaps and preventing flames and smoke from passing through. This simplifies the disassembly and assembly of the sealing structure, facilitates subsequent maintenance operations, optimizes the packing replacement procedure, and ensures the sealing performance of the device.
