中文摘要	本发明涉及水中软体油囊的注(排)油口装置，具体地说是一种穿墙式密封油嘴，包括油嘴外套、油嘴内衬、穿墙外套及管接头，油嘴内衬的一端位于油囊内，另一端由油囊钻出、与所述管接头的一端螺纹连接，管接头的另一端与油管相连；所述油嘴外套与油嘴内衬螺纹连接，通过螺纹预紧力与油嘴内衬的一端压紧油囊囊壁、并密封；所述穿墙外套位于油嘴外套的下方，穿墙外套的一端与油嘴内衬螺纹连接，另一端与油嘴内衬密封。本发明靠油嘴内衬与油嘴外套的螺纹预紧力通过两者之间的斜面以及斜面上对应位置的止口压紧油囊囊壁实现密封，避免了传统的油囊油嘴采用多个螺栓穿过油囊壁连接内衬与外套带来的密封隐患，结构简单，安全可靠。

英文摘要	The invention relates to oil injection (discharge) mouth device of an underwater soft oil sac, and in particular relates to a through-wall type seal oil nozzle. The through-wall type seal oil nozzle comprises an oil nozzle jacket, an oil nozzle lining, a through-wall jacket and a pipe joint, wherein one end of the oil nozzle lining is located in the oil sac, the other end of the oil nozzle lining is drilled out from the oil sac and is connected with one end of the pipe joint by threads, and the other end of the pipe joint is connected with the oil pipe the oil nozzle jacket is connected with the oil nozzle lining by threads, the wall of the oil sac is tightly compressed and the oil sac is sealed by thread pretightening force and one end of the oil nozzle lining the through-wall jacket is located below the oil nozzle jacket, one end of the through-wall jacket is in threaded connection with the oil nozzle lining, and the other end of the through-wall jacket and the oil nozzle lining are sealed. According to the through-wall type seal oil nozzle, sealing is realized by means of thread pretightening force of the oil nozzle lining and the oil nozzle jacket through an inclined plane between the oil nozzle lining and the oil nozzle jacket and a seam allowance at corresponding position on the inclined plane, the hidden sealing hazard caused by the oil nozzle of the traditional oil sac, which is formed by enabling a plurality of bolts to penetrate through the wall of the oil sac so as to connect the lining and the jacket can be avoided, and the through-wall type seal oil nozzle is simple in structure, and safe and reliable.
