The invention relates to the technical field of ship penetration parts, in particular to a watertight penetration pipe fitting. The watertight cabin penetration pipe fitting comprises an inner pipe, an outer pipe and a mounting flange. The inner pipe is sleeved with the outer pipe, a cooling cavity is defined between the outer pipe and the inner pipe, and the cooling cavity is provided with a cooling medium inlet and a cooling medium outlet; a mounting flange is arranged on the outer pipe, and the flange is used for being connected with a bulkhead. In other words, the watertight cabin penetration pipe fitting achieves the technical effect of reducing the temperature of the cabin wall under the high-temperature working condition through the design of the cooling cavity.

    本发明涉及船用通舱件技术领域,特别是涉及一种水密通舱管件。该水密通舱管件,包括内管、外管和安装法兰。外管套设在所述内管的外部,且所述外管与所述内管之间限定出冷却腔,所述冷却腔设有冷却介质进口和冷却介质出口;安装法兰设于所述外管,所述法兰用于与舱壁相连接。即是,该水密通舱管件通过冷却腔的设计实现了降低高温工况下舱壁温度的技术效果。
