Teach you to understand the electric actuator wiring diagram
First of all, to figure out the meaning of the various logos, and then understand the connection method, and then learn to see the different styles of the map.
Electric valve actuators can be divided into AC (AC110V, AC220V, AC380V) and DC (DC24V, DC12V) according to the power supply voltage. They are divided into active switch type, passive switch type, potentiometer type and regulation type according to the control mode.
Through the different wiring diagrams below:
1, active switch type, ordinary switch type with source light indication wiring diagram
2, passive switch type, switch type passive contact type with feedback wiring diagram.
3, opening degree potentiometer type, switch type with opening degree wiring diagram.
4, intelligent adjustment type, input and output 4-20mA, intelligent adjustment wiring diagram.
5, AC380V, with passive contact feedback, 380V power supply wiring diagram.
The types and classification of butterfly valves, butterfly valves can be divided into offset plate type, vertical plate type, slant plate type and lever type according to the structure. According to the sealing form, it can be divided into two types: a relatively sealed type and a hard sealed type. The soft seal type is generally sealed with a rubber ring, and the hard seal type is usually sealed with a metal ring. According to the connection type, it can be divided into flange connection and clip type connection. According to the transmission mode, it can be divided into manual, gear transmission, electric, pneumatic and hydraulic.
For a wide variety of butterfly valves, and in special working conditions, the corresponding butterfly valve products are also different, so for such valves, it should be selected in cooperation with engineers.
