Flat gate valve capable of being vertically installed

The utility model relates to the technical field of gate valves, in particular to a flat gate valve capable of being vertically installed, which comprises a valve body, a valve seat, a gate plate, a valve cover and a valve rod. The sealing surface formed by the gate plate and the valve seat is parallel to the gate plate in the full-open state of the flat gate valve, and the problem of internal leakage caused by damage of the sealing surface due to tilting of the gate plate is thoroughly solved. 本实用新型涉及闸阀技术领域，具体涉及一种可垂直安装的平板闸阀，包括阀体、阀座、闸板、阀盖和阀杆，本实用新型在阀盖内设置带有中心孔的导向板，通过其对闸板头部的定位与支撑作用，保证了平板闸阀全开状态下闸板和阀座所形成的密封面与闸板的平行，彻底解决了闸板翘起导致密封面被破坏而内漏的问题。
