Description
Technical field
The utility model is specifically related to a kind of more times angle Electric Actuator.
Background technique
Existing Electric Actuator sends instruction, shaft band dynamic torque to the executing agency executed in case by adjuster
Output shaft rotation exports corresponding angle value, and the rotational angle of torque output shaft determines open and-shut mode and the unlatching of control valve
Degree, but the rotation of torque output shaft often leads to the opening degree of last control valve because of the reason of there are rotator inertias,
That is there is a certain error for the opening angle angle value and setting value of control valve, to affect angle distance electric executor pair
In the control precision of control valve, to affect entire technological effect.
Summary of the invention
Goal of the invention: it in order to overcome the deficiencies in the prior art, provides and a kind of has rotational angle limit function
More times angle Electric Actuator.
Technical solution: to achieve the above object, the utility model provides a kind of more times angle Electric Actuator, including executes
Case, control cabinet, shaft, torque output shaft and the adjuster in control cabinet, it is described execute case outer wall on be provided with turn
Dynamic device device, the rot device are circular ring structure and are arranged with the section of torque output shaft in outer concentric circles, described turn
It is provided with the rotating disc of circular ring type on dynamic device device, is provided with limited block on the rotating disc, is arranged on the torque output shaft
There is the limit transverse bar matched with limited block, the rot device is connected to controller.
Further, there are certain distances between the rot device and torque output shaft, avoid rot device
Being in contact with torque output shaft influences the normal rotation of torque output shaft.
Further, the controller is located in control cabinet.
The utility model has the advantages that the utility model is compared with prior art, limited block is turned to by specific bit by rotating disc in advance
It sets, blocks limit transverse bar using limited block to limit to torque output shaft, to ensure that the output of torque output shaft
In high precision, because of the influence of inertia, the lower problem of the output accuracy of torque output shaft, to improve electronic before solving
Control precision of the actuator for control valve.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the schematic cross-section of rot device and torque output shaft.
Specific embodiment
In the following with reference to the drawings and specific embodiments, the utility model is furtherd elucidate, it should be understood that these embodiments are only used for
Illustrate the utility model rather than limitation the scope of the utility model, after having read the utility model, art technology
Personnel fall within the application range as defined in the appended claims to the modification of the various equivalent forms of the utility model.
As depicted in figs. 1 and 2, the utility model provides a kind of more times angle Electric Actuator, including executes case 1, control cabinet
2, shaft 3, torque output shaft 4 and the adjuster 8 in control cabinet 2, it is described execute case 1 outer wall on be provided with rot
Device 5, the rot device 5 are circular ring structure and are arranged with the section of torque output shaft 4 in outer concentric circles, the rotation
It is provided with the rotating disc 6 of circular ring type on device device 5, is provided with limited block 61 on the rotating disc 6, on the torque output shaft 4
It is provided with the limit transverse bar 41 matched with limited block 61, the rot device 5 is connected to controller 7, the rot
There are certain distance between device 5 and detection torque output shaft 4, the controller 7 is located in control cabinet 2.
The operation workflow of the utility model are as follows: the valve opening degree required first according to this technique calculates torque
The correspondence angle of rotation angle value of output shaft 4 first inputs angle of rotation angle value on controller 7 and starts rot device 5, and rotating disc 6 is opened
Begin to rotate corresponding angle value, limited block 61 is in this corresponding final position of torque output shaft 4 after rotating disc 6 rotates
Then angle of rotation angle value is sent instructions to the executing agency executed in case 1 by adjuster 8 again by place, executing agency's starting turns
The rotation of axis 3 drives torque output shaft 4 to turn to specified angle value, and limited block 61 can block limit transverse bar 41, prevents to turn round
Square output shaft 4 ensures that the actual rotation angle value of torque output shaft 4 is equal to the rotation of setting because inertia continues to rotate
Angle value.
