Description
Technical field
The utility model relates to a kind of electric component, and is especially relevant with a kind of electric actuator and integrated control cabinet thereof.
Background technology
Actuator (final controlling element) is the device of accepting control information in the automation equipment and controlled object being applied control action.In Process Control System, actuator is made up of actuator and governor motion two parts.Governor motion directly changes the parameter of production process by executive component, makes production process satisfy predetermined requirement.Actuator then accepts the control information of self-controller that it is converted to the output (as angular displacement or straight-line displacement output) that drives governor motion.It also adopts suitable executive component, but requires different with governor motion.Actuator is directly installed on the production scene, and condition of work is harsh sometimes.Can keep operate as normal directly to influence the fail safe and the reliability of automatic regulating system.The mode classification of actuator is as follows: (1) actuator is divided into pneumatic, electronic by used drive energy and three kinds of hydraulic actuators.(2) by the form of output displacement, actuator has two kinds of corner type and linear patterns.(3) by the action rule, actuator can be divided into switching mode, integral form and proportional-type three classes.(4) by input control model, several classes such as actuator is divided into can the input air pressure signal, dc current signal, electric contact make-and-break signal, pulse signal.
In the prior art, the integrated control cabinet of electric actuator is the control maincenter of actuator.Integrated control cabinet comprises it being the body of control cabinet, mainframe box just, and two ends are respectively arranged with first end cap and second end cap, also comprise loam cake, and first end cap wherein is provided with on-the-spot manual operator.Be equipped with the integrated of all control system in first end cap, it is made up of various electronic components, is provided with terminal board in second end cap.The task one of this control cabinet is to finish set design function, comprises access of on-site manual operation, signal cable and control cable or the like, the 2nd, and protect electronic component can not be subjected to the erosion of water and moisture.Usually, first end cap of loam cake and manual operator end all has sealing ring to guarantee sealing, generally no longer opens after installation, so sealing property guarantees easily.The terminals of terminal board also have sealing ring, generally, as long as install appropriately, also can play the better seal effect.But these terminals are owing to there is cable to insert, there are not water-proof function or the bad sealing cable junctions of water-proof function if use, will cause moisture even water to enter in the terminal cavities, thereby cause the moisture-proof function of control cabinet to lose efficacy, this also is the disadvantage of at present common structure control case.For having a humid climate and the area of heavy rainfull, this problem is especially outstanding.
The utility model content
The purpose of this utility model is to eliminate problems of the prior art, provides a kind of electric actuator integrated control cabinet, strengthens sealing property, prevents that effectively moisture from corroding.
Another purpose of the present utility model is, a kind of electric actuator with the integrated control cabinet of the utility model electric actuator is provided.
For achieving the above object, the integrated control cabinet of electric actuator of the present utility model comprises mainframe box, first end cap, second end cap, loam cake and outer wiring cavity, and the mainframe box top connects loam cake, first end cap is the end cap with on-the-spot manual operator, is connected in an end of mainframe box; The mainframe box other end connects outer wiring cavity, and the outer wiring cavity end connects second end cap; In the first end cap mounted inside the integrated of all control system arranged, the outer wiring cavity mounted inside has terminal board, be provided with seal between loam cake and mainframe box, first end cap and mainframe box, outer wiring cavity and second end cap, described terminal board adopts isolation structure, and outer wiring cavity and mainframe box are isolated fully.
The integrated control cabinet of electric actuator of the present utility model, preferred, described isolation structure is encapsulated in inner terminal and external terminal in the plastic plate, between terminal board and the mainframe box, between outer wiring cavity and the mainframe box, be provided with sealing ring.
The integrated control cabinet of electric actuator of the present utility model, preferred, described seal is a sealing ring.
Electric actuator of the present utility model has the integrated control cabinet of electric actuator of the present utility model.
Electric actuator of the present utility model, preferably FPi electric actuator.
The beneficial effects of the utility model are:
Compared with prior art, the integrated control cabinet of electric actuator of the present utility model, the structure of its " double containment " control cabinet, moisture has to external world adopted the two-stage isolation, is particularly suitable for having a humid climate or the area of heavy rainfull.Cable for terminals inserts, even without water-proof function or the bad sealing cable junctions of water-proof function, can not cause moisture even water to enter in the terminal cavities yet, thereby effectively strengthen the moisture-proof function of control cabinet, overcome the disadvantage of non-double sealing structure control cabinet in the prior art.
