Abstract
A solenoid valve with a hard seal structure includes a valve body having a fluid passage and an accommodating cavity, and a valve assembly mounted inside the accommodating cavity. The valve assembly includes a fluid inlet seat, a valve core cooperating with the fluid inlet seat, and a driving mechanism for driving reciprocating motion of the valve core. The fluid inlet seat has a guide hole that allows the value core to stretch therein, a middle section of the fluid inlet seat has fluid inlet holes, and a lower section of the fluid inlet seat has a valve core fluid passage and a fluid passage slant located at the valve core fluid passage. The valve core includes a bigger-diameter section, a slant section, a smaller-diameter section and a valve core end slant sequentially arranged from up to down.
