1. An electromagnetic valve, mounted on a mounting base, wherein the electromagnetic valve comprises:
a valve body, at least comprising a valve seat, wherein the valve seat is mounted on the mounting base;
a magnetic conductive frame fixed to the valve seat; and
an electromagnetic driving assembly mounted in the magnetic conductive frame;
wherein the magnetic conductive frame is provided with a positioning member, and the positioning member is capable of cooperating with the mounting base so as to restrict the electromagnetic driving assembly from rotating relative to the mounting base;
the valve seat further comprises a clamping portion, which is provided proximal to the magnetic conductive frame, a part of the clamping portion protrudes from the mounting base along an axial direction of the valve seat, and the clamping portion is provided with at least two clamping planes; and
the positioning member is provided at an end of the magnetic conductive frame proximal to the valve seat.
