The magnet-shielding tube 10 serves as an outermost component of the solenoid valve, and can confine brake fluid inside the solenoid valve and prevent the brake fluid from leaking to the outside of the magnet-shielding tube 10. In order to prevent the valve body 20 and the parts such as the moving iron 402 and the push rod 403 in the magnetic mechanism 40 from being rusted due to being exposed in the external space, the magnetic shield can enable the valve body 20 and the parts such as the moving iron 402 and the push rod 403 in the magnetic mechanism 40 to be placed in the magnetic shield, and therefore technical defects that the parts such as the moving iron 402 and the push rod 403 in the valve body 20 and the magnetic mechanism 40 are rusted due to being in contact with the external space, and further electromagnetic performance of the parts such as the moving iron 402 and the push rod 403 in the valve body 20 and the magnetic mechanism 40 is affected are effectively overcome. The open end 101 of the magnetism isolating tube 10 is a passage for the brake fluid inside the cavity of the magnetism isolating tube 10 to flow out, and the closed end 102 of the magnetism isolating tube 10 seals the brake fluid.
