Title:
REVERSIBLE ELECTROMAGNETIC VALVE
Document Type and Number:
WIPO Patent Application WO/2022/242719
Kind Code:
A1
Abstract:
A reversible electromagnetic valve (100), comprising a valve seat (10) having a valve port (11), a sliding block (20) slidably connected to the valve seat (10), and a driving member (30). The driving member (30) can drive the sliding block (20) to move in attachment to the valve seat (10) to use a sealing surface (22) of the sliding block (20) to selectively block the valve port (11). The sealing surface (22) of the sliding block (20) comprises a sealing point (21); the sealing point (21) is provided corresponding to a limit position of the edge of the valve port (11) on the valve seat (10), such that when the sliding block (20) drives the sealing point (21) to cross the valve port (11), the sealing surface (22) of the sliding block (20) can block the valve port (11); and under the action of a pressure difference, a position where the sealing point (21) on the sliding block (20) is located is not lower than a plane where the edge of the valve port (11) is located. The reversible electromagnetic valve can prevent interference from occurring between the position where the sealing point (21) on the sliding block (20) is located and the edge (12) of the valve port of the valve seat (10), so as to ensure the effective sealing of the valve port (11) on the valve seat (10) when the sliding block (20) closes the valve.
