Problems solved by technology

Valves with conventional design, such as valves with worm gear and worm transmission mechanism alone, often have air leakage due to air travel when the valve is closed, and in the event of a valve failure, effective control cannot continue to ensure the safety of the stratospheric airship. Safe to fly, so the safety factor is not high

Abstract

The invention provides a connecting rod double-redundancy valve device for a near space airship. The connecting rod double-redundancy valve device for the near space airship comprises a first valve system, a second valve system and a valve machine base; the first valve system and the second valve system are symmetrically installed on the two sides of the valve machine base; the first valve systemand the second valve system each comprise a valve deck, a motor, a transmission mechanism and a connection rod mechanism; the motors are fixedly connected with the valve machine base through motor supporting bases; output shafts of the motors are connected with input shafts of the transmission mechanisms; output shafts of the transmission mechanisms are connected with the valve decks through the connection rod mechanisms; and the motors can drive the transmission mechanisms so that the connection rod mechanisms can be driven to move, and therefore the valve decks are driven to move, and opening or closing of the valve decks is achieved. According to the connecting rod double-redundancy valve device for the near space airship, the worm and gear transmission mechanisms and the connection rodmechanisms are adopted and overcome the gas leaking defects of a valve, the double-redundancy design is adopted, and the reliability and the adaptability of an airship valve device are improved greatly.

Description

technical field [0001] The invention relates to the technical field of airborne aircraft hardware, in particular to a connecting rod double-redundancy 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. Valves with conventional design, such as valves with worm gear and worm transmission mechanism alone, often have air leakage due to air travel when the valve is closed, and in the event of a valve failure, effective control cannot continue to ensure the safety of the stratospheric airship. Safe flight, so the safety factor is not high. Contents of the invention [0003] The...
