Embodiment Construction

[0015] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] Such as Figure 1 ~ Figure 2 As shown, the present invention has designed a kind of submersible vehicle launching cylinder valve mechanism, and this mechanism comprises outer cylinder 1, sliding sleeve 2, base 3, electric actuator 4, external socket 5, liquid level sensor 6, gas filling nozzle 7, Sealing member 8, slide block 9 etc. are formed. The outer cylinder 1 is connected with the rest of the launch tube to form a complete launch tube; the outer cylinder 1 is the main load-bearing part of the valve, which can withstand the pressure of water depth, and four water inlet holes are symmetrically opened on it for seawater to enter the launch tube , the top of which is provided with a connection interface with ...

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of launch, in particular to a valve mechanism for a launch tube of a submarine aircraft. Background technique [0002] When the submarine-launched aircraft is launched, seawater needs to be introduced into the launch tube from the tail of the launch tube through the valve mechanism, and the launch device outside the tube drives the sea water to eject the aircraft out of the tube. In order to reduce the energy loss when seawater flows through the valve, the size of the valve channel needs to be increased as soon as possible, and it can be opened and closed reliably. In addition, due to the limitation of the launching device, the outer dimension of the valve cannot exceed the outer dimension of the launching tube, and it is integrated with the launching tube, and it is convenient to perform various operations on the launching tube. None of the existing valves meets the above requirements. Contents of the in...
