Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of rotary fine adjustment valve and controlling method thereof, degree of regulation can reach more than 0.1% of full scale (maximum opening), can overcome the deficiencies in the prior art.
Technological scheme of the present invention: a kind of rotary fine adjustment valve, comprise electric control valve, described electric control valve passes through lazy-tongs by stepper motor) and the driving of driver output axle, wherein stepper motor is connected with lazy-tongs, lazy-tongs are connected with driver output axle, driver output axle is connected with electric control valve, driver output axle is provided with the angular displacement sensor for detecting its angle information, this angular displacement sensor is connected with controller, controller is connected with stepper motor by driver module again, wherein, described driver module is used for clockwise and anticlockwise and the speed of control step motor.
The precision of described angular displacement sensor is more than 0.1 degree.
After instruction is communicated to controller by user, the driver output axle current angular information that angular displacement sensor detects by controller is compared with input angle instruction; If input angle is greater than current angular, then controller instruction issuing is to the driver module of stepper motor, and control step motor rotates forward, and moves and arrive input angle position to make driver output axle; If input angle is less than current displacement, then controller instruction issuing is to the driver module of stepper motor, control step motor reversal, rotates and arrive input angle position to make driver output axle; If input angle equals current angular, then controller control driver module and stepper motor are failure to actuate; In driver output axle rotation process, angle information is transferred to controller by angular displacement sensor in real time, realizes the closed loop control of valve opening.
After instruction is communicated to controller by user, the outer corner difference of the driver output axle current angular information that controller calculating angular displacement sensor detects and input angle, if this outer corner difference is greater than the half of the driver output axle total angle of rotation, then controller is assigned the mode that half corner rotational velocity before instruction control step motor is greater than later half corner rotational velocity and is rotated.
The described driver output axle total angle of rotation is that electric control valve is opened required corner stroke from being closed to by driver output axle completely.
The invention has the beneficial effects as follows:
The present invention, by the corner information of the feedback of angular displacement sensor, regulates control valve opening dynamically, realizes the closed loop control to valve opening.The control accuracy that the present invention regulates can reach 0.1% of full scale (maximum opening), meets the application that Pressure control or flow control required precision is higher completely.
