Fracturing gate valve for wellhead

The utility model relates to the technical field of gate valves, in particular to a fracturing gate valve for a wellhead, which comprises a valve body, a handle is arranged at the top of the valve body, a valve rod is fixedly connected to the bottom of the handle, and the bottom end of the valve rod penetrates through the top of the valve body and is movably connected with the top of the valve body. Sand in a medium is isolated through the inner filter screen, the medium can enter the valve body through the filter screen, only a small amount of sand enters the valve body and adheres to the outer side of the valve plate, in the flowing process of the medium, the medium can carry impact force to impact the surfaces of the multiple buffer plates, the buffer plates drive the elastic buffer strips to deform, and therefore the buffer effect is improved. The deformed buffer strip is used for buffering impact force generated in the medium flowing process, and the situation that the impact force directly acts on the s
