Zusammenfassung:	The utility model relates to the technical field of valves, in particular to a forged steel gate valve which comprises a circulation pipeline, a valve port is formed in the middle of the top of the circulation pipeline, a valve body is fixed to the inner wall of the valve port, a gate cavity is formed in the valve body, a gate groove is formed in the middle of the bottom of the circulation pipeline, and the specification of the gate groove is matched with that of the gate cavity. A sealing sleeve is attached between the inner wall of the gate groove and the bottom of the inner wall of the gate cavity, and a gate plate is fixedly arranged on the inner wall of the sealing sleeve. According to the forged steel gate valve, the operation mode that sealing is conducted only through a gate plate is replaced, other sealing structures are arranged between the gate plate and the circulation pipeline, a gap generated between the gate plate and the circulation pipeline is eliminated, and the gate plate of the whole forge
