Solenoid valve anti-rebound device and method

The invention discloses an electromagnetic valve anti-rebound device and method. The electromagnetic valve anti-rebound device comprises a device body, an electromagnet, an inductor and a processor. A guide column is arranged on the device main body; the electromagnet is slidably arranged on the guide column; the processor is electrically connected with the electromagnet and the inductor; the inductor is arranged on the device body and used for sending out an induction signal when it is inducted that the electromagnet passes through a preset distance. The processor is used for acquiring the current direction of the electromagnet and an induction signal of the inductor and controlling the current flowing direction of the electromagnet; the processor is used for enabling the electromagnet to circulate current in the attraction direction after the induction signal is obtained. According to the scheme, after the electromagnet passes through the preset stroke, current in the attraction direction flows through the
