Switch type and adjustable electrical part structure
1 switch type: control system and electric device are integrated into one, and it is called integrated switch electric device. Its electrical part is mainly composed of switch module, knob module, opening meter (or digital indicator), contactor and so on, as shown in Figure 4. The electrical components are mounted on a flip sheet to adjust the torque control mechanism, the stroke control mechanism, and the opening indicator. There are two knobs on the knob device, one is the state knob (the right side), the other is the operation knob (left side), depending on the electric housing, the arrow indicates the operation mode, the operation knob clockwise swirling to the arrow is the opening valve, and the counterclockwise is the closing valve.
2 regulation type: the regulating system is introduced on the basis of switch mode, that is, the regulating electric device is formed. Its electrical part is composed of adjusting module, knob assembly, opening meter (or digital indicator), contactor and so on. 4~20mA standard signal can be received and output
