Abstract
Disclosed is a magnetic pressure retaining control device, which comprises: a valve seat, a magnetic valve cover, and a trigger magnetic member for repelling the magnetic valve cover; the magnetic valve cover and an open end of the valve seat are movably connected; when the magnetic valve cover is in an open state, the trigger magnetic member is opposite to an end surface of the magnetic valve cover away from an inside of the valve seat. A cylindrical magnet is also arranged in the valve seat. By the magnetic between the trigger magnet and the magnetic valve cover, and the magnetic between the magnetic valve cover and the valve seat, a reliable guarantee for the closure between the magnetic valve cover and the valve seat is provided. The valve seat and the valve cover are tightly closed under different conditions.
