Problems solved by technology

Ordinary valves often adopt a single-redundancy design. In the event of a valve failure, effective control cannot be continued to ensure the safe flight of the stratospheric aerostat, so the safety factor is not high

Abstract

The invention relates to a dual-redundancy valve device applied to a stratosphere aerostat. The dual-redundancy valve device is composed of an inner set of subsystem and an outer set of subsystem, namely, a main subsystem and an auxiliary subsystem, wherein the inner set of subsystem and the outer set of subsystem are symmetrical about a valve machine base. An inner valve cover corresponds to the main subsystem, and an outer valve cover corresponds to the auxiliary subsystem. The main structure of the dual-redundancy valve device comprises a dual-redundancy valve cover, transmission mechanisms and the valve machine base, and each valve cover corresponds to one set of transmission mechanism. Each transmission mechanism comprises a prime motor, a turbine, a worm and other main structures. All devices are installed on the valve machine base used for supporting all components and transmitting a load to a bag body. A feedback signal of a micro-switch can be used for feeding an in-place state of a valve back, and provide an outage basis. The opened angle of each valve cover is measured through rotation, and the measurement of the switching value is achieved. A pressure measuring air nozzle is used for measuring differential pressure of the bag body, and provides a basis for controlling. A hollow boss is arranged on the inner valve cover and can be cut down by a cutting device when failure happens, and reliability of the system is improved.

Description

technical field [0001] The invention relates to a double-redundancy valve device used in a stratospheric aerostat, which is a device for adjusting the pressure difference of a capsule and the amount of gas loaded in a stratospheric aerostat, belonging to the airborne aerostat The field of hardware technology. Background technique [0002] In an aerostat that relies on static buoyancy to balance gravity, it is very critical to control the static buoyancy of the aerostat and the pressure difference between the inside and outside of the capsule. Therefore, the airborne dual-redundancy valve device is the key equipment to realize the stable lift-off and safe landing of the aerostat. Ordinary valves often adopt a single-redundancy design. In the event of a valve failure, effective control cannot be continued to ensure the safe flight of the stratospheric aerostat, so the safety factor is not high. The invention adopts a double redundancy design, uses the main and auxiliary valv...
