ELECTROMAGNETIC VALVE HAVING HARD SEALING STRUCTURE

The present invention relates to a solenoid valve with a hard seal structure, the solenoid valve comprising a valve body inside which a fluid passage and an accommodating cavity are provided and a valve assembly mounted inside the accommodating cavity, the fluid passage being communicated to the accommodating cavity. The valve assembly comprises a fluid inlet seat, a valve core cooperating with the fluid inlet seat for closing or opening the fluid passage, and a driving mechanism for driving reciprocating motion of the valve core. The fluid inlet seat is provided with a guide hole that allows a lower end of the valve core to stretch therein, a middle section of the fluid inlet seat is provided with a plurality of fluid inlet holes which are circumferentially arranged along the fluid inlet seat, and a lower section of the fluid inlet seat is provided with a valve core fluid passage and a fluid passage slant located at an upper portion of the valve core fluid passage for adjusting fluid flow. The valve core comprises a big-diameter section, a slant section, a small-diameter section and a valve core end slant in this order from up to down. Compared with the prior art, the present invention employs a hard seal assembling method, which is not easy to cause leakage, thereby greatly increasing service life of the solenoid valve.
