Abstract

The invention relates to the technical field of vacuum valve operation and particularly discloses a manual vacuum valve operation mechanism used for the nuclear. In the operation mechanism, the right side of a box body of a cylindrical structure is sealed through a flange assembly, a shaft is fixed inside the box body through a shaft sleeve arranged on a middle hole in the flange assembly on the right side, and the shaft is made to be connected with a sliding block assembly right side structure threaded pair arranged in the box body in a matched manner; the right side structure in the sliding block assembly sleeves the inside of a left side structure, and a disc spring installed between the right side structure and the left side structure makes the right side structure clamped in the left side structure be relatively compressed relative to the left side structure; and the lower end of the sliding block assembly right side structure is provided with a hole matched with the end of a lower valve body level assembly, and leftwards and rightwards movement of the sliding block assembly drives the end of the lower valve body level assembly to move leftwards and rightwards. According to the manual vacuum valve operation structure, the connection mode of the sliding block assembly and a transmission shaft can be utilized, a valve core is manually controlled to perform valve operation of horizontal movement or swing movement and sealing, operation is convenient and fast, and labor is saved.

Description

technical field [0001] The invention belongs to the technical field of vacuum valve operation, and in particular relates to a nuclear manual vacuum valve operating mechanism. Background technique [0002] The Chinese patent "Electric Torpedo Vacuum Valve for Nuclear Use" (patent number: ZL 201010599203.X) discloses an electric torpedo vacuum valve for nuclear use. The valve is electrically operated and can be remotely controlled. However, in the event of a circuit failure in the accident state, the system pipeline cannot be cut off in time. Therefore, it is necessary to design a nuclear manual vacuum valve operating mechanism to meet the safe operation of the system. [0003] Normally, nuclear manual vacuum valves are structurally composed of two parts: the operating mechanism and the lower valve body. Through the left and right movement of the sliding element in the upper valve body, the valve core in the lower valve body is driven to move, thereby realizing the opening an...
