PRODUCT STRUCTURE

1 Integrated control unit Non-sunk switch button is adopted to ensure complete waterproof function. The built-in circuit board has a reliable power isolation from external interference signals by optical isolation elements. If there is an over-torque switch induction, for the safety of the motor and valve, the actuator will refuse to be sensed by other sensors before the operator inputs the home position (RESET) button.

2 Selection of control mode

The selective switch "Remote"-"Stop"-"Local" installed on the local operating device can be used to set up remote operation (remote control) or local operation (local control) or stop mode.

3 Local electric operation

The operating switch "Open"-"Close" installed on the local operating device can be used to open or close actuator locally.

4 Motor

The valve-specific motor that can be disassembled independently has the characteristics of high starting torque and small inertia. The squirrel cage induction motor with embedded thermostat. The built-in thermostat accurately detects the increased temperature to prevent form motor damaging.

5 Electric operation

The motor drives the electric worm through a first-stage spur gear pair, and the worm drives the eccentric shaft to rotate through the copper worm gear combined with it. This reduction gear structure has self-locking performance, when the motor stops, the valve will be locked in position.

6 Stroke control, torque control and opening indicating mechanism

Stroke control It adopts a cam mechanism, the cam shaft is synchronized with the output shaft and two micro switches are respectively set in the opening and closing directions.The upper end of the cam shaft is equipped with a dial to indicate the valve position. Torque control The electric worm is equipped with a butterfly spring group, the axial movement of the electric worm is proportional to the output torque of the output shaft, and the movement of the worm is converted into the rotation of the torque shaft through the rack and pinion structure. A cam is installed on the torque shaft, and a microswitch is provided correspondingly in the direction of opening and closing.

7 Manual operation

When the handwheel is turned, the manual worm drives the outer gear of the fixed ring gear to rotate, and the inner gear of the fixed ring gear and the planetary gear form a fixed-axis gear train to drive the output shaft to rotate. Therefore the manual and electric operation conversion of the actuators is completed through the role conversion of the static ring gear. There is no clutch, and there is no need to switch the handle to achieve fully automatic switching.

8 Terminal box

The independent sealed terminal cavity can ensure the sealing integrity of the electrical part of the electric actuator when performing on-site wiring, and at the same time meet the product explosion-proof requirements.

9 Mechanical limit

There is an adjustable limit screw in each direction of opening and closing. A special sealing gasket is installed on the limit screw to ensure good sealing performance of this part.

Mobile APP wireless remote control electric valve overview:

The mobile phone APP wireless remote control electric valve control part realizes the local valve opening and closing signal output control and open position signal acquisition (optional). Low post-maintenance cost, strong environmental adaptability; high communication frequency. The centralized control device is composed of switch knob/button, box body, and communication control circuit board (industrial computer/pc/tablet/mobile phone is optional). The centralized control device and the valve unit realize one-to-many communication, and the opening and closing of the valve is unified by the centralized control center control. The valve unit realizes the shut-off control of the pipeline fluid. After the area location is divided and the communication address is bound, it can be remotely controlled by the corresponding switch knob/button on the centralized control device
