Abstract

Provided are a valve module and a solenoid valve. The valve module includes: a valve assembly (10), the valve assembly (10) being provided with a first accommodating cavity (11), a piston cavity (12), and a pilot valve port (13); a movable iron core (20) movably arranged in the first accommodating cavity (11), the movable iron core (20) being provided with a valve needle main cavity (21); a piston assembly (30), the piston assembly (30) being configured to open and close the pilot valve port (13), the piston assembly (30) being provided with a through piston channel (31), an end of the piston channel (31) serving as a pressure relief port (311), and an other end of the piston channel (31) being in communication with the pilot valve port (13); a return spring (40) arranged in the first accommodating cavity (11), the return spring (40) applying an elastic force to the movable iron core (20); and a small valve needle (50) arranged in the valve needle main cavity (21), wherein in a state that the pilot valve port (13) is closed, the movable iron core (20) is capable of abutting against the piston assembly (30), and the small valve needle (50) closes the pressure relief port (311). The elastic force of the return spring (40) of the valve module can act on the piston assembly (30) by means of the movable iron core (20), so that the solenoid valve is reliably opened and closed. The elastic force of the return spring (40) is prevented from directly causing a relatively large impact on the pressure relief port (311), thereby ensuring the sealing at the pressure relief port (311) during long-term use.
