According to the present invention, a gate valve with a linkage structure comprises: at least one power cylinder; a valve body having a valve opening unit; a gate assembly, in the valve body, having a main gate board and a sealing gate board neighboring each other, and connected to one end part of the sealing gate board by at least one parallel linkage; and at least one press bar pivoting one end part on the sealing gate board and extending the other end to form a pressing end unit. A linkage bar is pivoted on the press bar and the main gate board. Accordingly, the gate assembly is operated to seal the valve opening unit, the sealing gate board is moved to be apart from the main gate board with a linkage function, and sealing force is generated to keep sealing between the sealing gate board and the valve opening unit. |
