Abstract

The invention provides a valve device for a near space airship. The valve device includes a base, a valve cover, a driving mechanism, a connection rod mechanism and a controller. A gas vent is formed in the base; the valve cover is arranged on the top surface of the base, and the valve cover is in pivotal connection with the base so as to open or close the gas vent; the driving mechanism is fixed on the bottom surface of the base; one end of the connection rod mechanism is in pivotal connection with the driving mechanism, and the other end of the connection rod passes through the gas vent and is in pivotal connection with the valve cover; the controller controls the driving mechanism so as to drive the connection rod mechanism, and the pivotal movement, relative to the base, of the valve cover is achieved so as to open or close the gas vent. Moreover, the valve device further comprises a limiting device and a cutting device. A connection rod transmission structure and a valve emergency cutting device are adopted, and the valve device has higher reliability and emergency response capability.

Description

technical field [0001] The invention belongs to the field of aerospace technology, in particular to a valve device for an airship near space. Background technique [0002] Near space airships rely on static buoyancy to balance gravity and achieve lift. In the flight envelope, it is extremely important to control the air intake of the hull capsule and the pressure difference between the inside and outside of the capsule. Therefore, the on-board valve device is the key equipment to realize the stable launch and safe landing of airships in adjacent space. With conventionally designed valves, when the valve is closed, there is often air leakage due to empty travel, and in the event of a valve failure, effective control cannot be continued to ensure the safe flight of the airship in adjacent space, so the safety factor is not high. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned problems existing in the prior art, esp...
