Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0022] As shown in Figure 1 , Figure 2 , a fireproof arc-shaped pipe-through-cabin sealing device is used in cooperation with a valve remote transmission mechanism and is installed on a fireproof bulkhead 1. The fireproof bulkhead 1 is provided with an installation hole. The fireproof arc-shaped pipe-through-cabin sealing device comprises a pipe through the cabin 2. The pipe through the cabin 2 is installed in the installation hole and is perpendicular to the fireproof bulkhead 1, that is, the pipe through the cabin 2 vertically penetrates the fireproof bulkhead 1. The pipe through the cabin 2 is provided with a connecting main shaft 3. The two ends of the connecting main shaft 3 can be welded or fixedly connected by fasteners with corresponding parts (such as a driving mechanism, a shaft coupling, a rigid shaft, etc.) in the valve remote transmission mechanism, so as to serve as a transmission shaft for transmitting torque. Alternatively, the connecting main shaft 3 can directly serve as a transmission shaft in the valve remote transmission mechanism to directly transmit torque. The two ends of the connecting main shaft 3 are provided with fireproof sealing rings 4. The fireproof sealing rings 4 are used to ensure that the connecting main shaft 3 is sealed with the pipe through the cabin 2 and to ensure the fireproof performance. One end of each of the fireproof sealing rings 4 is provided with an end cover 5. The end cover 5 is connected with the pipe through the cabin 2 and is used to tightly seal the end of the entire device.

[0023] In actual application, the connecting main shaft 3 is a stepped shaft. The two ends of the connecting main shaft 3 can be further provided with bearings 6. The bearings 6 are arranged on one side of the fireproof sealing rings 4. The bearings 6 are used for radial support and axial positioning of the connecting main shaft 3 and facilitate rotation of the connecting main shaft 3. The bearings 6, the fireproof sealing rings 4, the pipe through the cabin 2 and the connecting main shaft 3 are positioned and installed by shaft shoulders during installation. The installation sequence of each other is selected and adjusted according to the actual situation on site.

[0024] In actual application, the two ends of the connecting main shaft 3 can be provided with connecting ports 31, which are pin interfaces. The connecting ports 31 are used to connect with corresponding parts in the valve remote transmission mechanism, so that the connecting main shaft 3 can quickly transmit torque on both sides of the fireproof bulkhead 1.

[0025] In practical application, the end cover 5 is uniformly provided with a plurality of connecting holes 7 in the circumferential direction, the locking members 8 are matched and connected in the connecting holes 7, the through-passage pipe 2 is uniformly provided with a plurality of locking holes 9 in the circumferential direction at two ends, the locking holes 9 are aligned with the connecting holes 7 one by one, and the locking members 8 are matched and connected in the locking holes 9. The connecting holes 7 can be counter-sunk holes, the locking holes 9 can be threaded holes, the locking members 8 can be counter-sunk screws or internal hexagonal bolts, and the end cover 5 and the through-passage pipe 2 are locked and fixed by the matched connection of the locking members 8 with the connecting holes 7 and the locking holes 9 in sequence.

[0026] In practical application, the through-passage pipe 2 includes a first horizontal pipe 21, an arc-shaped pipe 22 and a second horizontal pipe 23, which are integrally formed or welded and fixed in sequence, the first horizontal pipe 21 and the second horizontal pipe 23 are vertically arranged on the two sides of the fireproof bulkhead 1 respectively, and the arc-shaped pipe 22 is double-sided welded and installed in the mounting hole, that is, the outer contour surface of the arc-shaped pipe 22 is welded with the two side surfaces of the fireproof bulkhead 1. After welding, the welded part is polished and the weld is cleaned to ensure the watertight requirement of the welded part. The first horizontal pipe 21 and the second horizontal pipe 23 are coaxially arranged in the form of a cylindrical cylinder or a hollow pipe, and the length and diameter of the two can be consistent. The arc-shaped pipe 22 is in the form of a hollow sphere or ellipsoid, the outer contour cross section is in the form of a circle or an ellipse, or the upper and lower parts of the outer contour cross section are in the form of arcs. The overall shape of the through-passage pipe 2 can be composed of a hollow cylindrical cylinder with a sphere or ellipsoid penetrating through the middle.

[0027] In practical application, the diameter of the first horizontal pipe 21 and / or the second horizontal pipe 23 is smaller than the diameter of the mounting hole, so that one end of the through-passage pipe 2 is inserted into the mounting hole, and the diameter of the mounting hole is smaller than the diameter of the outer contour of the arc-shaped pipe 22. Since the installation of the through-passage pipe 2 on the fireproof bulkhead 1 is finally achieved by installing the arc-shaped pipe 22 in the mounting hole, and the upper and lower parts of the outer contour cross section of the arc-shaped pipe 22 are in the form of arcs, the precision requirement of the diameter of the mounting hole to be opened on the fireproof bulkhead 1 is reduced, and the diameter of the mounting hole only needs to be between the diameter of the first horizontal pipe 21 or the second horizontal pipe 23 and the diameter of the outer contour of the arc-shaped pipe 22, thereby reducing the construction difficulty of complex site.

[0028] In practical application, the fireproof sealing ring 4, the end cover 5 and the bearing 6 are arranged in the first horizontal pipe 21 and the second horizontal pipe 23 respectively.

[0029] In practical application, the first horizontal pipe 21 is provided with a first mounting groove, the arc-shaped pipe 22 is provided with a mounting channel 10, and the second horizontal pipe 23 is provided with a second mounting groove, and the first mounting groove, the mounting channel 10 and the second mounting groove are sequentially communicated. The fireproof sealing ring 4, the end cover 5 and the bearing 6 are respectively arranged in the first mounting groove and the second mounting groove, and the connecting main shaft 3 is sequentially arranged in the first mounting groove, the mounting channel 10 and the second mounting groove. The first mounting groove and the second mounting groove are both stepped grooves, and the structures of the two grooves are consistent and symmetrical about the arc-shaped pipe 22. The mounting channel 10 is a cylindrical through hole, and the middle part of the connecting main shaft 3 is connected with the mounting channel 10 through hole-shaft gap cooperation or transition fit.

[0030] In practical application, the fireproof sealing ring 4 is a graphite packing ring, which has good fireproof performance, can ensure the sealing between the connecting main shaft 3 and the cabin-penetrating pipe 2 and ensure the fireproof performance, and does not need to be filled with fireproof material between the connecting main shaft 3 and the cabin-penetrating pipe 2 after installation.
