Summary:The utility model belongs to the field of gate valves, and particularly relates to a gate valve with high sealing performance, which comprises a valve body, a threaded rod and a gate plate which are arranged between two groups of pipelines, one end of the pipeline is inserted into the other end of the valve body, a threaded rod matched with the internal threads is arranged in the valve body, and a gate plate is movably installed at the bottom end of the threaded rod through a bearing. A sealing mechanism is arranged in the valve body and comprises a limiting assembly, a rubber sleeve and a rubber block, the gate plate is movably installed in the valve body through the limiting assembly, and a sealing ring is glued to the upper end of the gate plate. The problem that the sealing performance between the gate plate and the valve body is poor is solved, through the sealing mechanism, the situation that when the gate plate shields the interior of the valve body, a medium flows out from the position between the gat
