Abstract
The utility model discloses an electric actuator for valve, including step motor, reduction gear, step motor contains step motor driver, step motor controller, step motor's output shaft with the input of reduction gear link to each other, step motor driver and step motor controller intercommunication, the reduction gear is connected with the valve, step motor be two step motor of play, one of them of step motor dual output axle is equipped with the hand wheel, step motor's the output shaft and the input of reduction gear are directly continuous, the reduction gear is turbine worm reducer. The utility model discloses need not to set up the high feedback device of price, reduce cost, valve switching angle is steerable, has the manual adjustment means behind the power failure.
Description
Technical field
The utility model relates to field of electromechanical technology, especially relates to a kind of valve electric actuator.
Background technique
The electric actuator of control valve in prior art, adopts accurate motor drive mechanism to control, and arranges feedback means, and thus integral electric valve class price is high, limits its using scope.
Summary of the invention
The utility model adopts feedback means to solve existing Valve controlling, cause sky high cost, the problem that the occasion making to apply valve-gating technology is less, there is provided without the need to arranging the high feedback means of price, by controlled driving stepper motor retarder, thus control valve opening and closing angle, realize Valve controlling object valve electric actuator.
To achieve these goals, the utility model is by the following technical solutions: valve electric actuator, comprise stepper motor, retarder, described stepper motor comprises stepper motor driver, controllor for step-by-step motor, the output shaft of described stepper motor is connected with the input end of described retarder, described stepper motor driver is communicated with controllor for step-by-step motor, and described retarder is connected with valve.This programme adopts controllor for step-by-step motor output pulse signal, this pulse signal is delivered to stepper motor driver, thus control step motor driver, make Driving Stepping Motor do angular displacement to rotate, rotating valve after retarder is rotated in the angular displacement of stepper motor, and with arbitrarily angled startup and valve can be stopped, therefore achieving adopt this valve pipeline in the adjustment of flow.
As preferably, described stepper motor is for two shaft or singly go out shaft step motor.
As preferably, a wherein axle of described stepper motor double output shaft is provided with handwheel.Arranging handwheel is backup means, when the power-fail of valve electric actuator, can use manpower rotation hand wheel, the angle of manpower regulating valve, and avoiding after power-fail cannot the problem of regulating valve.
As preferably, the output shaft of described stepper motor is directly connected with the input end of retarder, or is connected by coupling.Stepper motor is directly connected with retarder, and namely stepper motor output shaft is the input shaft of retarder; Also be connected by coupling, axle sleeve.
As preferably, described retarder is turbine and worm retarder.
Therefore, the utility model has following beneficial effect: (1), without the need to arranging the high feedback means of price, reduces costs; (2) valve opening and closing angle can control; (3) manual tune means are had after power-fail.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
In figure: 1, handwheel 2, stepper motor 3, retarder 4, valve
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
In embodiment as shown in Figure 1, valve electric actuator, comprise stepper motor 2, retarder 3, stepper motor 2 comprises stepper motor driver, controllor for step-by-step motor, the output shaft of stepper motor 2 is connected with the input end of described retarder 3, stepper motor driver is communicated with controllor for step-by-step motor, retarder 3 is connected with valve 4, stepper motor 2 for two go out shaft step motor, a wherein axle of stepper motor 2 double output shaft is provided with handwheel 1, the output shaft of stepper motor 2 is directly connected with the input end of retarder 3, and retarder 3 is turbine and worm retarder.
Specific implementation process is, controllor for step-by-step motor output pulse signal, this pulse signal is delivered to stepper motor driver, thus control step motor driver, make Driving Stepping Motor do angular displacement to rotate, rotating valve 4 after retarder 3 is rotated in the angular displacement of stepper motor 2, and with arbitrarily angled startup and can stop valve 4; When after power-fail, manpower rotation hand wheel 1 can be used, the angle of manpower regulating valve 4.
