Description of drawings
Fig. 1 is broken section structural representation of the utility model Electronic-Type Dynamic Balance Electric Control Valve and erection drawing.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
A kind of Electronic-Type Dynamic Balance Electric Control Valve as shown in Figure 1 comprises electronic valve component 5 and the analog amount electric actuator 4 that links to each other with electronic valve component 5, is used for implementing the analog amount adjusting of electronic valve body.Valve body is gone into head piece 1, electronic valve component 5, valve body and is gone out head piece 9 and connect successively by nut/bolt standard piece 8, perhaps is processed into mechanical integrated structure.
Under the known given situation of valve regulating characteristic, when valve two ends dynamic differential pressure measured value is known, intelligent controller 3 can be imported setting value to dynamic control signal and carry out directly exporting after the corrected Calculation, realize the adjusting correction of valve mechanical opening, thereby realized the transient equiliblium of valve flow.
When analog amount electric actuator 4 was opened the valve body in the electronic valve component 5, water was gone into head piece 1 from valve body and is flowed into, stream electronic valve component 5 after, the runner that goes out head piece 9 from valve body goes out stream.
Described intelligent controller 3 both can adopt the universal controller that has senior mathematical function computing function and can realize pid control algorithm, also the developing intellectual resource controller product exploitation of single-chip microprocessor MCU (for example based on) specially.Intelligent controller 3 also is provided with some I/O tenminal blocks 6.
Giving regularly when the dynamic control signal input setting value of the controller of outside input (is the setting that outside input mode is carried out the dynamic flow value, this flow setting value only depends on control signal, irrelevant with valve pressure at two ends difference), corresponding dimensionless dynamic control signal input setting value variable is also promptly given.When valve two ends dynamic differential pressure measured value and dynamic differential pressure setting value generation deviation, utilize desirable equal percent regulating characteristic to calculate correction formula, intelligent controller 3 calculates nondimensional dynamic control signal output value easily, can obtain the dynamic control signal output value of dimension by linear transformation.
