Description

Technical Field

[0001] This utility model relates to an intelligent valve positioner. Background Technology

[0002] Valve positioners, classified by structure into pneumatic valve positioners, electro-pneumatic valve positioners, and intelligent valve positioners, are the main accessories of control valves. They are usually used in conjunction with pneumatic control valves. They receive the output signal from the controller and then use their output signal to control the pneumatic control valve. After the control valve is activated, the displacement of the valve stem is fed back to the valve positioner through a mechanical device, and the valve position status is transmitted to the upper system through an electrical signal.

[0003] As industry develops towards intelligence and automation, positioners are increasingly used in valves to achieve valve control. However, with the increase in valve types and the growing demand for precise valve control, existing positioners are no longer sufficient to meet the needs of some valves. Therefore, it is necessary to develop a new type of valve positioner. Utility Model Content
