Problems solved by technology

This structure cannot achieve intelligent control technically, which makes installation and debugging complicated and requires professional operation. It is easy to drift in the case of vibration and is not stable enough.
When more than 2 stations are required to be controlled, because the position control uses the limit switch method, it is impossible to use one of the products currently on the market.
[0003] Domestic products in the same industry mainly use ordinary motors as the power components of the actuators, but it is currently impossible to implement high-precision control technology, so the control of the valve stroke can only be achieved by using a stroke switch and a position sensor to control the valve position. The control accuracy is low, and the limit switch is easy to loosen under the condition of vibration, which requires professional personnel to carry out maintenance and debugging

Embodiment 1

[0024] Such as Figure 1-3 A digital intelligent angular stroke electric actuator shown includes a top plate 1 on which a reducer 2, a power supply module 3, a stepping motor 4, a motor drive controller 5 and a multi-position adjustment module are arranged. 6. The top of the reducer 2 is provided with a control board 7, the top of the control board 7 is provided with a mechanical position display module 8, the top of the stepping motor 4 is provided with a junction box 9, and the bottom of the top board 1 is provided with a manual An integrated transmission mechanism 10 and a handwheel mechanism 11, the bottom of the hand-automatic integrated transmission mechanism 10 is provided with a bottom plate 12, the side wall of the bottom plate 12 is provided with a mechanical limit adjustment mechanism 13, and the bottom of the bottom plate 12 is provided with a connecting flange 14. The bottom of the connecting flange 14 is provided with an output interface 15 .

Embodiment 2

[0033] Such as Figure 1-3 As shown, the connecting flange 14 is connected with the flange on the valve to install the quarter-turn electric actuator, so that the bottom end of the rotating shaft 16 is connected with the valve stem above the valve, and the CPU in the control panel 7 issues a control command to make The angular stroke electric actuator enters the initialization stage, and controls the forward rotation of the stepper motor 4 through the motor drive controller 5, the output shaft of the stepper motor 4 is connected to the reducer 2, and drives the rotating shaft 16 in the reducer 2 to rotate, which will make the valve The valve stem on the top rotates to open the valve. When the limit rod 17 on the rotating shaft 16 moves to the side of the limit baffle 18, the mechanical limit is reached. At this time, the stepping motor 4 is blocked, and the position feedback sensor 19 stops rotating. At this time, no rotation signal is fed back to the CPU in the control board ...

Abstract

The invention discloses a digital intelligent angular travel electric actuator, and particularly relates to the field of process industry intelligent control. The digital intelligent angular travel electric actuator comprises a top board. A speed reducer, a power module, a stepping motor, a motor drive controller and a multi-station adjusting module are arranged on the top board. A control board is arranged on the top on the speed reducer, a mechanical position display module is arranged on the top of the control board, a terminal box is arranged on the top of the stepping motor, a manual-automatic integrated transmission mechanism and a hand wheel mechanism are arranged at the bottom of the top board, and a bottom board is arranged at the bottom of the manual-automatic integrated transmission mechanism. The stepping motor is adopted as a power unit, so that control is more precise; and meanwhile as the operation state of the stepping motor is monitored, the operation states of the actuator and a valve connected with the actuator can be accurately acquired, and self-diagnosis of the actuator and operation diagnosis of the valve connected with the actuator are achieved.

Description

technical field [0001] The invention relates to the field of intelligent control of the process industry, and more specifically, the invention relates to a digital intelligent angular stroke electric actuator. Background technique [0002] The electric actuators currently on the market use ordinary motors as power components, potentiometers as position sensing components, and travel switches as control components for zero position and 100% position. This kind of structure cannot achieve intelligent control technically, which makes installation and debugging complicated and requires professional operation. It is easy to drift under the condition of vibration and is not stable enough. When more than 2 stations are required to be controlled, because the position control is the travel switch method, it is impossible to use one of the products on the market at present. [0003] Domestic products in the same industry mainly use ordinary motors as the power components of the actua...
