ELECTROMAGNETIC VALVE

WIPO Patent Application WO/2024/027513

A1

Disclosed is an electromagnetic valve, comprising: a valve (10) comprising a valve body (11) and a valve port arranged in the valve body (11), the valve body (11) being internally provided with a mounting cavity; a valve core part (20), the valve core part (20) being movably arranged in the mounting cavity, to open or close the valve port, the valve core part (20) comprising a valve core body (21) and a stopper portion (22), and the stopper portion (22) being arranged on the end of the valve core body (21) facing the valve port; and a sealing structure (30) sleeved on the valve core body (21), wherein the sealing structure (30) comprises a first sealing portion (31) and a second sealing portion (32) connected to each other, the second sealing portion (32) being located outside the first sealing portion (31) in the radial direction of the sealing structure (30). The second sealing portion (32) is provided with a recess (321). An inner peripheral wall of the recess (321) away from the first sealing portion (31) is at a preset distance from an outer peripheral surface of the second sealing portion (32); or, the inner peripheral wall of the recess (321) away from the first sealing portion (31) extends to the outer peripheral surface of the second sealing portion (32). The problem of easy leakage at a valve port when the electromagnetic valve is in a closed state can be solved.
