High-temperature and high-pressure double-flat-plate gate valve

The utility model relates to the technical field of valves, in particular to a high-temperature and high-pressure double-flat-plate gate valve, which overcomes the defect that a valve rod of an existing double-flat-plate gate valve is easy to bend and break, and comprises a valve body, a valve seat fixedly connected in the valve body, a gate plate arranged in the valve seat, and the gate plate realizes opening and closing of the valve body through traction of the valve rod. The gate valve is characterized in that the gate plates are connected with the valve rod through the gate plate frame, the gate plate frame is provided with a T-shaped groove and connected with the valve rod through the T-shaped groove, valve seats on the two sides of the gate plates and the valve body are fixed into a whole through welding to form a valve body assembly, the two gate plates are connected into a whole through the gate plate frame, and a spring is arranged between the two gate plates. According to the gate valve, the baffles
