The invention discloses an emergency breathing system of a large-depth manned submersible, and relates to the field of diving equipment.The emergency breathing system comprises a high-pressure oxygen bottle, the high-pressure oxygen bottle is connected with a first high-pressure valve assembly through an air pipe, and a second silencing filter comprises a silencing filter body and an air inlet connecting pipe; a mounting mechanism for connecting the first silencing filter with an air pipe is arranged on the outer side of the air inlet connecting pipe; and a positioning mechanism for limiting the threaded sleeve is distributed on the threaded sleeve. By arranging the positioning mechanism, the threaded sleeve is screwed between the air pipe and the air inlet connecting pipe and between the air pipe and the air outlet connecting pipe, and at the moment, the threaded sleeve can be limited by inserting a second positioning pin into an annular clamping groove, so that the stability of connection between the air pipe and the air inlet connecting pipe and between the air pipe and the air outlet connecting pipe is improved; afterwards, the L-shaped connecting rod and the threaded sleeve are simultaneously out of limit through the connecting mechanism, so that convenience is provided for subsequent disassembly and replacement of equipment.
本发明公开了一种大深度载人潜水器应急呼吸系统,涉及潜水设备领域,包括高压氧气瓶,所述高压氧气瓶通过气管连接有第一高压阀体总成,所述第二消声过滤器包括消声过滤器主体、进气连接管,所述进气连接管的外侧设置有用于所述第一消声过滤器与气管连接的安装机构;所述螺纹套管分布有用于对所述螺纹套管进行限位的定位机构。本发明通过设置定位机构,通过将螺纹套管拧至气管与进气连接管、出气连接管之间,此时可通过第二定位销插入环形卡槽内来实现对螺纹套管的限位,以此来增加气管与进气连接管、出气连接管之间连接的稳定性,之后可通过连接机构来使L形连接杆、螺纹套管同时失去限位,从而为设备后续的拆卸、更换提供了便利。
