Abstract
The invention relates to an efficient electric actuating mechanism capable of being manually controlled. The efficient electric actuating mechanism comprises a handwheel and an electric actuating mechanism and further comprises a planetary gear speed reducing device, wherein the input end of the planetary gear speed reducing device is connected with the handwheel and the output end of the planetary gear speed reducing device is connected with the electric actuating mechanism. By manually rotating the handwheel, the power is transferred to the planetary gear speed reducing device and finally is transferred to an output shaft, so that the purpose of reducing speed and increasing torque is achieved. The transmission efficiency is improved, the purpose of emergently opening or closing a valve under the special condition is further achieved while the problem that the handwheel is labor-wasting to rotate, and the electric actuating mechanism is agile and convenient to operate.
Description
Technical field
The present invention 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.
Summary of the invention
The technical problem to be solved in the present invention 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 technical solution adopted for the present invention to solve the technical problems is: 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 invention has the beneficial effects as follows: 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.

Embodiment
The present invention will be further described in detail by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As Figure 1-3, the invention provides a kind of efficiently can the electric actuator of Non-follow control, comprise handwheel 1 and electric actuator 9, also comprise planetary reduction gear, the input end of described planetary reduction gear is connected with handwheel 1, and the output terminal of planetary reduction gear is connected with electric actuator 9.
As shown in Figure 3, described planetary reduction gear comprises casing 2, planet carrier 3, planet wheel 4, central gear 5, ring gear 6, input shaft 7 and output shaft 8, described handwheel 1 is fixedly connected with input shaft 7 one end, described central gear 5 is arranged on input shaft 7 the other end, described planet carrier 3 is at least installed a planet wheel 4, with central gear 5 and ring gear 6 gears meshing while of described planet wheel 4, described ring gear 6 is fixed on casing 2, described planet carrier 3 is fixedly connected with output shaft 8, described output shaft 8 is connected with the valve rod in electric actuator 9, described handwheel 1 center of rotation, input shaft 7 axis, output shaft 8 axis, central gear 5 center of rotation, planet wheel 4 revolution center and ring gear 6 axis collinear.
As shown in Figure 1, in order to prevent planet carrier 3 because of unbalance stress, uniform fixed installation three planet wheels 4 on described planet carrier 3.
Below in conjunction with Fig. 1, working principle of the present invention is described:
Manual rotation handwheel 1, handwheel 1 drives the input shaft 7 be fixedly connected with it to rotate, input shaft 7 drives connected central gear 5 to rotate by spline, central gear 5 rotates and drives the planet wheel 4 engaged with it to rotate, planet wheel 4 engages with ring gear 6 and together rotates, because ring gear 6 is fixed, planet wheel 4 starts to revolve round the sun around central gear 5 while rotation, the revolution of planet wheel 4 drives the planet carrier 3 of fixing planet wheel 4 to rotate, planet carrier 3 is connected with output shaft 8, planet carrier 3 rotates and drives output shaft 8 to rotate, output shaft 8 is connected with valve rod, and then by transmission of power to valve rod, valve rod drives valve core rotation, thus the control that realization promptly opens and closes valve.
