Description
Technical field
The utility model relates to a kind of electric actuator, especially a kind of efficiently can the electric actuator of Non-follow control.
Background technique
In recent years, along with the enforcement of a series of major projects such as China's transfering natural gas from the west to the east, the electric actuator be arranged on pipeline is widely used, electric actuator is used for the keying of control valve, to control flowing and the flow direction of all kinds fluids such as water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.
When occur power-off or motor go wrong do not start time, electric actuator cannot opening/shutting valve, the handwheel in artificial rotary electric actuator is now needed to carry out the keying of control valve, because the valve specification controlling large-scale pipeline is larger, its specification being arranged on the electric actuator on large-scale pipeline is also corresponding larger, the keying of the direct control valve of handwheel is rotated with hand, relatively effort, more cannot the keying of emergency control valve, to a certain extent fatal shortcoming is brought to the emergency episode work for the treatment of of pipeline, even indirectly cause the heavy losses of lives and properties.
Model utility content
The technical problems to be solved in the utility model is: in order to overcome effort when conventional electric actuator needs the direct control valve of hand rotation handwheel to open and close because having a power failure defect and can not the deficiency that promptly opens and closes of control valve in time, there is provided a kind of efficiently can the electric actuator of Non-follow control, between handwheel and electric actuator, set up planetary reduction gear, improve transmission efficiency.
The utility model solves the technological scheme that its technical problem adopts: a kind of efficiently can the electric actuator of Non-follow control, comprise handwheel and electric actuator, also comprise planetary reduction gear, comprise handwheel and electric actuator, it is characterized in that: also comprise planetary reduction gear, the input end of described planetary reduction gear is connected with handwheel, and the output terminal of planetary reduction gear is connected with electric actuator.
Further, described planetary reduction gear comprises casing, planet carrier, planet wheel, central gear, ring gear, input shaft and output shaft, described handwheel is fixedly connected with input shaft one end, described central gear is arranged on the input shaft the other end, described planet carrier is at least installed a planet wheel, with central gear and ring gear gears meshing while of described planet wheel, described ring gear is fixed on casing, described planet carrier is fixedly connected with output shaft, described hand wheel rotating center, input shaft axis, output shaft axis, central gear center of rotation, planetary gear revolution center and ring gear axis collinear.
In order to avoid planet carrier is because of unbalance stress, uniform fixed installation three planet wheels on described planet carrier.
The beneficial effects of the utility model are: by setting up planetary reduction gear between handwheel and electric actuator, improve transmission efficiency, solve the problem that convention manual transmission rotates effort when the direct control valve of handwheel opens and closes, the effect that timely control valve promptly opens and closes can be realized, flexible and convenient operation simultaneously.
