For example, a servo solenoid valve for automobile ABS system that is easy to detect is disclosed in Chinese patent announcement number CN215720858U. However, when the closed hole in the solenoid valve and the closed block are not in close contact due to insufficient elastic force of the spring, a new spring needs to be replaced to make the pressure of the closed block reach the specified size. In addition, since the spring is inside the solenoid valve, it is more troublesome for maintenance personnel to repair the solenoid valve. Utility Model Content
