Valve linkage provided in this embodiment can be applied to valve, especially large-scale smoke-and fire-preventing valve.Specifically,
The first main shaft spinner handle in one linkage mechanism and the second main shaft spinner handle in the second linkage mechanism respectively in large size valve not
It is connected with valve group, a valve group may include a minor valve, or include multiple minor valves being mutually sequentially connected.Normal
State, valve are open state.When needing to close valve, start electric operator, electric operator drives after being powered
The first main shaft spinner handle rotation in first linkage mechanism is to drive the valve block in the valve group connecting with the first main shaft spinner handle to turn
It is dynamic.While the rotation of the first main shaft spinner handle, the rotation of the second main shaft spinner handle is driven by linkage rope, to drive and the second main shaft
Valve block rotation in the adjacent valve group of spinner handle, so that each valve block in valve rotates, it will be in entire large size valve
Multiple groups valve be turned off.
As shown in Figures 2 and 3, in a kind of specific embodiment of the present embodiment, the first linkage mechanism includes: first main
Axis spinner handle 31, the first locking piece 32 and the first elastic drive part 33, the first locking piece 32 and the first main shaft spinner handle 31 are separable
Connection, for driving the rotation of the first main shaft spinner handle 31, the first elastic drive part 33 revolves the first elastic drive part 33 in the first main shaft
