AI Technical Summary
Existing solenoid valves require continuous power during operation, resulting in high energy consumption and heat generation, which affects equipment operation.
It adopts a combination structure of valve core, indexing plate, stepper motor and elastic connector. It controls the air circuit switch by short power supply and uses the stepper motor to drive the indexing plate to rotate to change the air circuit state, thereby reducing the continuous power supply time of the solenoid valve coil.
This reduces the energy consumption of the solenoid valve, decreases heat generation, and improves the operating efficiency and reliability of the equipment.
