The gas valve control actuating device is used as a missile attitude control device, is a core component for missile attitude adjustment, and has to meet the requirements of small volume, high precision and high response of the valve control device, which brings about a small challenge for the design of the actuating device.
The actuating device is composed of two driving mechanisms, two push rods, two linear displacement sensors and a controller, and flow regulation of four channels of the valve is achieved. The actuating device has a complex overall structure, is usually installed in a split type series connection mode, namely a driving mechanism is installed on a valve body, a controller is installed on the upper end face of the actuating mechanism, a push rod is connected with an output shaft of the driving mechanism and installed at the lower end of the actuating mechanism in a cantilever mode, and the linear motion of the push rod is achieved through limiting of an inner cavity of the valve body so as to achieve the purpose of controlling the flow rate of a gas valve. This type of mounting forms a typical three-layer structure (controller, drive mechanism, push rod).
Due to the limitation of the structure volume, the displacement sensor is arranged on an output shaft of the driving mechanism and cannot be directly connected with the push rod. The push rod is in a cantilever state, elastic deformation is easily generated when the push rod is stressed, the displacement sensor feeds back the position of an output shaft of the driving mechanism, and the real-time position of the push rod after stress deformation cannot be accurately fed back, so that output feedback distortion is caused, debugging and compensation are required to be performed through control, time and labor are wasted, and errors exist. Meanwhile, the controller, the driving mechanism and the push rod are installed in series from top to bottom, so that the occupied space is large in volume, the space utilization rate is low, and the requirement of the actuating system on small volume cannot be met.
