Valve mechanism for submarine-carried aircraft launch canister

The invention relates to a valve mechanism for a submarine-carried aircraft launch canister and relates to the technical field of launching. The valve mechanism can be matched with other parts of thelaunch canister to form the complete launch canister, so that a good storage space is provided for an aircraft. Normal opening/closing can be conducted according to instructions of a control device ona submarine, and after opening, seawater enters the launch canister to achieve seawater pressure equalizing of a launch canister front cover. The good rigidity and intensity are achieved, and the water depth pressure load can be withstood; and the good airtightness is achieved, and thus the aircraft is located in a good dried environment. 本发明涉及种潜载飞行器发射筒阀门机构，涉及发射技术领域。本发明能够与发射筒其他部分配合，形成个完整的发射筒，为飞行器提供良好的贮存空间；能够按照艇上控制设备的指令，正常开启/关闭，开启之后，海水进入发射筒内，实现发射筒前盖的海水均压；具有良好的刚强度，能够抵御水深压力载荷的作用；具有良好的密封性，使得飞行器处于良好的干燥环境中。
