Example Embodiment
[0022] The present invention will be further described below with reference to the drawings and embodiments.
[0023] Such as figure 1 , The double redundancy valve control system is composed of a dedicated controller, a motor driver, etc., which can detect the working state of the valve, automatically switch the working mode, and receive application system instructions. The valve is driven by two stepping motors to drive the slide valve and the rotary valve respectively. Motor 1 drives the spool valve action of the double redundancy valve, and motor 2 drives the rotary valve action of the double redundancy valve. The two motors are driven by their respective drivers. The driver can provide the power of the stepping motor and support the control pulse subdivision. The digital controller is the core of the system. On the one hand, the controller sends control pulses to the stepper motor driver to instruct the spool valve or rotary valve to act, and on the other hand, it can direc...
