The invention provides a gate valve for solving the problems that the sealing surface of the valve seat in the conventional gate valve is a wedge-shaped surface and is difficult to turn during production and the gate valve is easy to abrade and short in service life when being opened and closed due to high friction between the wedge-shaped surface of the gate valve and the wedge-shaped sealing surface of the valve seat. The gate valve comprises a valve seat, gate plates and a control device, wherein the valve seat is provided with a first sealing surface and a second sealing surface; the gate plates comprise a first gate plate and a second gate plate connected with the first gate plate; the control device is used for controlling the gate plates to enter the valve seat and the first gate plate and the second gate plate to splay at a distance so that the first gate plate is back to the surface of the second gate plate and is tightly matched with the first sealing surface, the second gate plate is back to the surface of the first gate plate and is tightly matched with the second sealing surface and the gate valve is closed, or controlling the gate plates to leave the valve seat and the first gate plate and the second gate plate to get close to each other so that the gate valve is opened; and the first sealing surface and the second sealing surface are perpendicular to the bottom of the valve seat and parallel to the gate plates. The gate valve is easy to produce and long in service life.
