Abstract
The utility model discloses a mining explosion suppression type integrated valve electric actuator, which comprises a torque controller. The torque controller comprises a circular rack, a gear shaft, a cam and a micro switch. The circular rack is disposed on a worm and is meshed with the gear shaft. The cam is fixed onto the gear shaft. The micro switch is arranged corresponding to the cam. According to the technical scheme of the utility model, when the mining explosion suppression type integrated valve electric actuator is in use, the output torque of the mining explosion suppression type integrated valve electric actuator can be effectively controlled.
Description
Technical field
The utility model belongs to technical field of valve control, particularly a kind of flame-proof mine integrated valve Electric actuator.
Background technique
Electric device for valve is to realize the indispensable driving arrangement of valve stroking, automatic control and remote control, and its movement process can be controlled by the size of stroke, torque or end thrust.
In the running of flame-proof mine integrated valve Electric actuator, on output shaft, can be subject to certain torque, when torque reaches certain value, make output shaft distortion, the torque control of flame-proof mine integrated valve Electric actuator has very large meaning.
Therefore, how controlling the torque of flame-proof mine integrated valve Electric actuator output shaft, is those skilled in the art's problem demanding prompt solutions.
Model utility content
In view of this, the purpose of this utility model is to provide a kind of flame-proof mine integrated valve Electric actuator, and this flame-proof mine integrated valve Electric actuator has been realized the effective control to output shaft torque.
For achieving the above object, the utility model provides following technological scheme:
A kind of flame-proof mine integrated valve Electric actuator, comprise moment control device, described moment control device comprises circular rack, tooth axle, cam and sensitive switch, the described tooth bar that turns is arranged on worm screw, described tooth bar is meshed with described tooth axle, described cam is fixed on described tooth axle, corresponding with described cam at described sensitive switch.
Preferably, described sensitive switch comprises out to sensitive switch and closes to sensitive switch, and described cam comprises out to cam and close to cam, described in open to sensitive switch with described in open to cam correspondingly, described pass is corresponding to cam with described pass to sensitive switch.
Preferably, described in, open to cam and described pass and be fixed by screws on described tooth axle to cam.
Flame-proof mine integrated valve Electric actuator provided by the utility model compared with the existing, because the utility model is provided with circular rack on worm screw, due to worm and wheel engagement, worm gear is coaxial with output shaft, circular rack is coaxial with worm screw, therefore, worm screw is rotated the circular rack driving on worm screw and synchronously rotates, drive worm gear and output shaft rotation simultaneously, when output shaft is subject to after certain torque, worm screw can produce certain axial displacement, circular rack on worm screw drives tooth axle to rotate, when output torque increases to while adjusting torque, cam on tooth axle touches sensitive switch, cut off motor power, thereby realize the control to Electric actuator output torque.
