[0003] After searching, the Chinese patent document announcement number: CN219866343U discloses a flat gate valve that can be installed vertically, including a valve body, a valve seat, a gate, a valve cover and a valve stem. The utility model arranges a guide plate with a center hole in the valve cover. Through its positioning and supporting function for the gate head, it ensures that the sealing surface formed by the gate and the valve seat is parallel to the gate when the flat gate valve is fully opened, and completely solves the problem of internal leakage caused by the sealing surface being damaged due to the gate tilting.

[0004] The beneficial effects of the above patent specification mention that "a guide plate with a center hole is arranged in the valve cover.
