Abstract

The invention provides a lead screw and rotary nut double-redundancy valve device for a near space airship. The lead screw and rotary nut double-redundancy valve device comprises a first valve system,a second valve system and a valve base, wherein the first valve system and the second valve system are symmetrically installed on two sides of the valve base; each of the first valve system and the second valve system comprises a valve cover, a driving motor and a transmission mechanism; each of the transmission mechanism comprises a gearbox and a lead screw which is connected to the gearbox through a rotary nut; the gear boxes are connected to the valve base through supports, the driving motors are connected to the gearboxes through motor mounting blocks, and the valve covers are fixedly connected to the lead screws through connecting grooves arranged on the valve covers; and the rotary nuts can convert torque transmitted by the drive motors through the gearboxes into linear motion of the lead screws so that the valve covers can be driven to move, and therefore the valve covers can be opened or closed. According to the lead screw and rotary nut double-redundancy valve device, the lead screws and the rotary nut gearboxes are adopted as the transmission mechanism to improve the air leakage defect of the valve, and the reliability of the airship valve device is improved through thedouble-redundancy design.

Description

technical field [0001] The invention relates to the technical field of airborne aircraft hardware, in particular to a double-redundancy valve device for a lead screw rotating nut used in 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 those using worm gears, 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 that the airship in the stratosphere is adjacent to space. safe flight, so the safety factor is not high. Contents of the invention [0003] The...
