Abstract:
Disclosed is a solenoid valve, comprising: a valve cover (60) and a valve core (20), the valve core (20) being mounted in the valve cover (60); a first sealing structure (43) and a sealing sleeve (42), the sealing sleeve (42) being mounted at one end of the valve cover (60), and the first sealing structure (43) being arranged at the end of the sealing sleeve (42) close to the valve cover (60) and forming a valve port (41); and a driving assembly (30), the driving assembly (30) driving the valve core (20) to move in the axial direction so as to open/close the valve port (41), wherein there is a hardness difference between a part, matched with the valve core, of the first sealing structure and the valve core. The problem in the prior art that medium leakage is prone to occurring at the valve port when the valve core blocks the valve port can be solved.
