Abstract:

A kind of adjustable flow control valve was designed and its structural characteristic and flow characteristic were analyzed. The adjustable flow control valve is pluggable and it can overcome the limitation of the fixed flow characteristic.  Simulation results showed that using different flow templates can change its structural characteristics, and then change its flow characteristic. The valve can be flexibly used  for different work requirements and can effectively improve the efficiency of control valve use.

Key words: control valve, adjustable flow, structural characteristic, flow characteristic
