Abstract
A hydraulic operated valve operation device solves the problems that a current valve operation device is large in size and poor in transmission stability due to less compact internal structure. The operation device is characterized in that two hydraulic cylinders, each with a cavity, are respectively arranged on two sides of an axial line of a rotating shaft; the cavities are connected with the outside through oil holes; pistons are arranged in the cavities; the two pistons are connected through a piston rod; and a rack meshed with a gear is arranged in the middle of the piston rod. According to the hydraulic operated valve operation device, by arranging the hydraulic cylinders and the pistons in a box body, when oil enters into the hydraulic cylinders, the pistons and the piston rods are pushed to drive a valve rod finally, and accordingly, the open/close of the valve is realized. Moreover, the hydraulic operated valve operation device has the advantages of compact internal structure, smaller size, and good transmission stability.
