The dynamic balance motor-driven modulating valve product of widely applying at present generally adopts the realization principle of spring mechanical self-powering type; Thereby having that through-current capability is obviously less than normal, transient equiliblium pressure reduction control range is little, application is dumb, the operating pressure differential initial value is higher, higher (because DP=DP totally consumes energy
1+ DP
2, the pressure that must sacrifice differential pressure controller during actual the use is kept the pressure reduction automatic constant of motorized adjustment part.The pressure of obviously sacrificing differential pressure controller also is the waste energy consumption).
The present known dynamic balance motor-driven modulating valve of also not finding a kind of energy collecting perceptional function.
