The intelligent motorized valve actuator is simple in structure and convenient for mounting and debugging. The intelligent motorized valve actuator comprises a controller which has a step control function and a PID control function, an electric actuation mechanism which is used for driving an adjustment ball valve to act, an LCD (Liquid Crystal Display) which is used for displaying pipeline pressure, set pressure, valve openness, operation interfaces and debugging menus, and an infrared or radio remote-control transceiver module which is used for receiving remote-control information. The intelligent motorized valve actuator is formed by combining the integrated PID and an electric actuator and integrates the function of the PID controller and the function of the adjustment type electric actuator, so that the costs of engineering designing, mounting and debugging are saved for users. The input sensing signals of temperature, pressure, differential pressure, flow, liquid level and the like are computed by a PID circuit module in the electric actuator, then the valve openness is controlled, the fluid state is caused to change, and finally the sensing signals enter a PID module through a sensing loop so as to form a closed-loop adjustment loop.

As preferred scheme, said adjusting ball valve is the V-type ball valve.
As preferred scheme, said electric actuator comprises totally enclosed type squirrel cage motor and the turbine that is connected with this electric-motor-driving; The rotating shaft of this turbine and said adjusting ball valve is in transmission connection.Turbine cooperates with the rotating shaft of regulating ball valve, is suitable for making actuator's work under the state of big moment, frequent clockwise and anticlockwise for a long time, with respect to the Placement of conventional keys, pin, has the characteristics of good stability.
The technique scheme of the utility model is compared existing technology and had the following advantages: the intelligent electric valve actuator of the band PID of (1) the utility model is the integrated PID and the bond of YE; The function of its existing PID controller (temperature, pressure, pressure reduction, flow, liquid level); The function that has the adjustment type YE has again been practiced thrift the cost of engineering design and Installation and Debugging for the user.It is the 4-20mA standard channel signal that the signal of this intelligent electric valve actuator inserts passage; Be used for transducing signals such as input temp, pressure, pressure reduction, flow and liquid level; The aperture of control valve after the calculating of the PID circuit module of these signals in YE, and then cause the variation of fluid state.Finally get into said PID module, form the closed-loop adjustment loop through sensing loop.(2) the intelligent electric valve actuator of the band PID of the utility model integrates sensing, calculating, control, driving, valve body manufacturing multiple technologies, simplify the workload of user's type selecting, and Installation and Debugging is more convenient.(3) controller is suitable for the PID setup parameter, and is simple and convenient and easy to study, and debugging work is simpler.(4) apolegamy infrared hand-held remote control device maintenances of exempting to uncap can be matched the telecontrol panel, the unhandy problem of final controlling element during solution piping erection in addition.(5) YE of the utility model is used to control ball valve; Can be used to control valve and other like products of 0 °～270 ° of rotations; Like butterfly valve, ball valve, air door, flapper valve, stopcock, blinds valve etc.; Can be widely used in oil, chemical industry, water treatment, boats and ships, papermaking, power station, heat supply, in the every profession and trades such as light industry.It is a driving power with the 380V/220V/110V ac power supply, is control signal with 4-20mA current signal or 0-10V DC voltage signal, can make valve motion to desired location, realizes its automation control; (6) housing is a hard aluminium alloy, and through anodizing and polyester powder coating, corrosion resistance is strong.Electric actuator adopts the totally enclosed type squirrel cage motor, and volume is little, and moment of torsion is big, and inertial force is little, and insulation class is the F level, and built-in overheat switch can prevent the cause thermal damage motor.(7) the charged sub-brake function of the YE of the utility model, accurate positioning.Sensitivity is adjustable, reaches as high as more than 0.5%, satisfies the various device demand.
Description of drawings
For the content that makes the utility model is more clearly understood, below basis specific embodiment and combine accompanying drawing, the utility model is done further detailed explanation, wherein
Fig. 1 is the structured flowchart of the intelligent electric valve actuator of the band PID among the embodiment.
Embodiment
See Fig. 1; The intelligent electric valve actuator of the band PID of present embodiment comprises: the controller with a formula control and pid control function; The electric actuator that is used to drive said adjusting ball valve action that links to each other with this controller; The LCD (liquid crystal display panel) that is used for display pipes pressure, setting pressure, valve opening, operation interface and debugging menu that links to each other with this controller; What link to each other with this controller is used to receive the infrared of remote information or wireless remotecontrol send receive module, to make things convenient for parameter setting and debugging.
Said controller is connected with RS485 communication interface or 3G wireless communication module or gsm wireless communication module, to realize remote wireless control.
Said adjusting ball valve is the V-type ball valve, and electric actuator comprises the totally enclosed type squirrel cage motor.
On-off type control is claimed in institute's rheme formula control again, is that measured value is compared than difference with setting value after processing and amplifying, controlled plant is opened or closed the adjusting of control.
Said PID is the meaning of PID.P representes that carrying out ratio in deviation amplifies and to obtain an output, and this can't eliminate surplus poor, therefore adds integration, and integration is by the deviation accumulation, as long as there is deviation that the integral value greater than (or less than) 0 is just arranged.Only so not enough, because deviation changes the branch that speed is arranged, therefore will use differential, differential is exactly the speed that calculation deviation changes.It is exactly PID control that three kinds of control laws of while user are controlled controlled variable.
Obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not to be qualification to the mode of execution of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all mode of executions.And conspicuous variation that these spirit that belong to the utility model are extended out or change still are among the protection domain of the utility model.
