Summary:The utility model discloses novel improvement for a hard sealing gate valve, which comprises a valve body and a gate plate arranged in the valve body. A medium channel is arranged in the valve body, two sealing ring faces are arranged on the medium channel in the valve body, two sealing faces are arranged on the gate plate respectively corresponding to the sealing ring faces, the gate plate moves vertically in the valve body to enable the sealing faces to be connected with or separated from the sealing ring faces and enable the medium channel to be closed or opened, and malposition structures are arranged on the sealing ring faces. The novel improvement is simple in structure, convenient to manufacture and low in cost. After the malposition structures are added, elasticity of connection of the sealing faces and the sealing ring faces is increased, differences of angle matching or surface unfairness between the sealing faces and the sealing ring faces in a processing process are corrected, so that matching of
