Abstract

The invention discloses a valve remote transmission device. The valve remote transmission device comprises a valve, a drive mechanism and a connection mechanism. The valve comprises a rotary hand wheel for driving the valve to open and close; the drive mechanism and the valve are arranged on two sides of an isolation component separately; the connection mechanism penetrates through the isolation component to be connected with the valve and the drive mechanism; the drive mechanism transmits power to the valve through the connection mechanism; the connection mechanism comprises a drive end directly connected to the rotary hand wheel; and the drive end is detachably connected with the rotary hand wheel. The valve and the drive mechanism are arranged on two sides of the isolation component separately, the overall structure of the valve does not need to be detached or the original structure of the valve does not need to be changed, the connection end of the connection mechanism is directlyand detachably connected with the rotary hand wheel of the valve, drive force is directly acted on the drive mechanism, and accordingly opening and closing of the valve are controlled, change of the structure of the valve is reduced, and the safety performance of the interior of the valve is also effectively ensured.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a valve remote transmission device. Background technique [0002] The nuclear power plant will shield and isolate the safe area through the screen door, and the on-site staff will not enter the inside of the screen door to operate. The valve used in the pipeline of the nuclear power plant is located inside the screen door through the valve body, valve seat and valve stem. The operating structure on the valve stem extends to the outside through the screen door; the operator operates the handwheel of the structure outside the screen door to realize the opening or closing of the valve. [0003] Similar to the setting method of valves in nuclear power plants, the valves currently buried in the ground also leak the operating structure above the ground, and the valve body, valve disc and valve stem are all buried in the ground. For example, Chinese patent document CN204573294U disclose...
