The present application provides a solenoid valve, comprising: a valve body assembly; a sleeve, which is connected to the valve body assembly; a coil assembly, at least one portion of which is sleeved on the sleeve; a sealing element, which is sleeved on the sleeve to block a gap between the coil assembly and the sleeve, or is sleeved on the valve body assembly to block a gap between the coil assembly and the valve body assembly; and a support portion, one end of which abuts against the sealing element, and the other end of which abuts against the valve body assembly. By using the solution, one end of the support portion abuts against the sealing element, the other end of the support portion abuts against the valve body assembly, and the sealing element is sleeved on the sleeve, such that the gap between the coil assembly and the sleeve or the gap between the coil assembly and the valve body assembly can be blocked by the sealing element, the coil assembly is prevented from water damage in the working process of the solenoid valve, and the problem of the coil assembly being corroded is avoided, thereby improving the working performance of the coil assembly, prolonging the service life of the coil assembly, and thus improving the sealing effect of the solenoid valve.
