The invention discloses a ship watertight bulkhead high-temperature cabin penetrating device which comprises a lining pipe, a lining ring and a high-temperature pipe, the inner diameter of the lining pipe is slightly larger than the outer diameter of the high-temperature pipe, the high-temperature pipe penetrates through the lining pipe, the two ends of the high-temperature pipe are connected with the lining pipe in a welded mode, and the lining ring is of a tubular structure with one open end and the other closed end. An open hole is formed in the closed end of the bushing ring, the outer diameter of the bushing ring is equal to three times of the diameter of the open hole, the diameter of the open hole is slightly larger than the outer diameter of the liner tube, the liner tube penetrates through the open hole and is connected with the bushing ring in a welded mode, and the bushing ring penetrates through the watertight bulkhead and is connected with the watertight bulkhead in a welded mode. The high-temperature pipe is isolated from the watertight bulkhead, so that heat transfer is blocked, paint of the watertight bulkhead is protected when the high-temperature pipe penetrates through the watertight bulkhead, complex structural forms such as double-layer sleeves are avoided, and the high-temperature pipe can safely penetrate through the watertight compartment with light structural weight and low cost.
本发明公开了一种船舶水密舱壁高温穿舱装置,包括衬管、衬环、高温管,所述衬管的内径略大于高温管的外径,所述高温管穿过所述衬管,所述高温管的两端与所述衬管焊接连接,所述衬环为一端开放、一端封闭的管状结构,所述衬环封闭的一端设置有开孔,所述衬环的外径等于所述开孔的直径的3倍,所述开孔的直径略大于所述衬管的外径,所述衬管穿过所述开孔并与所述衬环焊接连接,所述衬环穿过水密舱壁并与水密舱壁焊接连接。本发明将高温管与水密舱壁隔离开来,从而阻断传热,实现了高温管穿透水密舱壁时对水密舱壁油漆的保护,避免了双层套管等复杂的结构形式,以较轻的结构重量和较低的成本实现了高温管安全穿透水密舱。
