Technical field
The utility model belongs to electric device for valve control technique field, particularly relates to a kind of electric device for valve and rotates back to the switch type field control mechanism that turns.
Background technique
At present, the control mode of electromechanical equipment electric device for valve can be summed up as two kinds of patterns usually, one, and telecontrol is promptly controlled electric device for valve by the control signal that far-end is sent; Its two, field control promptly realizes electric device for valve is controlled by the field control operating device on the electric device for valve equipment.Electric device for valve execute-in-place mechanism includes scene/control conversion far away; The scene is driven valve, is closed control functions such as valve, shutdown; And the indication of electric device for valve equipment working state, as standard-sized sheet indication, power supply indication and complete shut-down indication etc.Electric device for valve execute-in-place mechanism is except that need possess above-mentioned control function, different application environment place according to equipment, also need possess certain protection, explosion-proof performance and certain boundary dimension requirement, this just brings certain specific (special) requirements to the design of electric device for valve execute-in-place mechanism.
In known technology, electric device for valve execute-in-place mechanism mostly is LED Unit, knob, knob shaft, switch obturating plug, structures such as base plate, switch adapter sleeve, rotary knob switch is installed.Knob shaft passes the switch obturating plug, and an end installs knob by screw, and the other end passes installs shifting block in the base plate insertion rotary knob switch; The rotary knob switch is provided with the switch adapter sleeve, and rotary knob switch and switch adapter sleeve are packed in the both sides that base plate is installed by screw thread, base plate and switch obturating plug is installed is solidly installed.Rotate " on-the-spot/control far away " switch, knob is placed on control shelves far away, this moment, Electric actuator was in the telecontrol state; Knob is placed on on-the-spot shelves, operation " open and close, stop " knob, the controllable valve valve electric device is driven valve, is closed valve events, and this moment, Electric actuator was in the field control state.
For this type of execute-in-place mechanism, structure is relatively complicated, and the design component are more, and especially the rotary knob switching position is installed complicated.From the switching manipulation angle, because each operation all needs to stir the rotary knob switch, steering force is big, causes the rotary knob switch to damage phenomenon often.The sealing configuration of knob shaft position is a turning O type ring recess on knob shaft, and the O type of packing into circle inserts knob shaft in the switch obturating plug again, and this sealing configuration causes easily often and cuts circle when assembling, influences the tightness of product.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, easy to install, increase work efficiency.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of electric device for valve rotates back to the switch type field control mechanism that turns, comprise knob and switch obturating plug, knob is installed on the switch obturating plug, be coated with knob shaft in the switch obturating plug, one end of knob shaft connects knob, the other end of knob shaft passes to be installed base plate and connects switch, switch is packed in to be installed on the base plate, base plate and switch obturating plug are installed to be solidly installed, install on the base plate LED Unit is installed, bidding quotation in that the exterior edge face of switch obturating plug is provided with is characterized in that: the switch that described knob shaft connects adopts and rotates back to the switch of turning; The described through hole that is provided with on knob is equipped with in the through hole and holds power spring and steel ball, and steel ball is positioned on the knob outer side surface, and the outside of spring is equipped with clam member, and clam member is installed on the knob by fastening piece, is provided with the groove with the steel ball coupling on bidding quotation.
The utility model can also adopt following technical measures:
Described at the switch obturating plug near processing annular seal groove on the knob shaft mounting hole of knob end, O-ring seals is installed in annular seal groove.
Advantage and the good effect that the utlity model has are: because the utility model adopts technological scheme, compared with prior art have the following advantages and good effect:
1, the annular seal groove of knob shaft position cancellation, mill out an annular seal groove at switch obturating plug front end, earlier knob shaft is inserted in the switch obturating plug, put into O-ring seals again, be about to knob shaft and be fixed in the switch obturating plug loading onto knob then, simple installation, this sealing means is less the circle phenomenon to occur cutting, has also improved barrier propterty of the present utility model simultaneously.
2, use the rotary knob switch that rotates back in the switch replacement existing structure of turning, reduced the thickness of switch so greatly, dwindled the assembly space of electric device for valve field control mechanism in casing.
3, rotate back to the switch of turning and compare the rotary knob switch, effectively raise the control reliability of Electric actuator, and rotating back to the switch of turning, to have stopped switch fully excessive because of multi-pass operation or steering force, the ruined phenomenon of the switch that causes.
4, knob is from top dress steel ball with hold the power spring, and by screw clam member pressing spring and steel ball, this fit is more convenient for installing; Slip in the groove on the bidding quotation by steel ball, thereby realize the control position that positioning knob stops, improve the polarization of switch.
