Abstract

The invention provides an electric mechanism for an aviation fuel valve, and belongs to the technical field of valve adjustment control. The electric mechanism comprises a motor, a shell, a speed reducer, magnetic steel, a pointer, a Hall sensor, a relay and an electric connector; the output end of the motor is connected with the speed reducer; the pointer is coaxially fixed with the output end of the speed reducer; the magnetic steel is fixedly connected with the pointer and coaxially rotates; the Hall sensor is arranged along the movement track of the pointer; and the electric connector is connected with a power supply, a superior system of the host and the relay. After the electric mechanism for the aviation fuel valve receives a specified position signal of a superior system, the current shaft locking position of an output shaft is judged according to position signal combinations of Hall sensors at different positions, then the current opening and closing position of a ball valve assembly is judged, and the rotating direction of a motor is judged after the current opening and closing position is compared with a given position, and the reversing operation of the motor is realized through the relay. Compared with the prior art, the invention has the advantages of high reliability and strong anti-interference capability, and meets the requirements of reliability and long endurance of aviation products.

Description

technical field [0001] The invention relates to the technical field of valve adjustment control, in particular to an electric mechanism for an aviation fuel valve. Background technique [0002] Fuel valves are widely used in the aerospace field, and electric actuators for fuel valves are also widely used as supporting aviation system products. The requirements for airborne equipment systems in the aviation field are different from those in aerospace. Taking the Air Force early warning aircraft airborne equipment system as an example, it contains strict design and test specifications, and the requirements for product life are much higher than aerospace products, and the requirements for reliability are extremely high. Product design is required to meet the requirements of high reliability, long endurance, and light weight for aviation products. [0003] The existing fuel valve electric mechanism uses a large number of electronic components to meet the detection and control r...
