Described valve position is opened to button 61 and valve position is closed and is positioned at opposite side on described control panel 6 to button 62, and described valve position is opened to instruction
Lamp 63 is opened between button 61 at described condition selecting knob 60 and valve position, and described valve position is closed and is positioned at described shape to display lamp 64
State selects knob 60 and valve position to close between button 62, and condition selecting knob includes that shape is demarcated in field control state LOCAL, valve position
State O and long-range controlled state REMOTE, select knob can select controlled state accordingly by artificial rotation status；Press valve position to open
To button, then valve runs to being opened to terminal location, presses valve position and closes to button, then valve is to closing to terminal location operation, valve
It is red colored lamp display lamp that position is opened to display lamp, and pass, valve position is green light display lamp to display lamp；
Then valve correspondence position and valve position are opened to display lamp and pass, valve position to the logic state corresponding relation of display lamp is:
Valve opening process: red light dodges, green light；
Valve wide open position: when red, green light goes out；
Valve closing process: green light dodges, when red；
Valve closed positions: green light, red light dodges；
Valve centre position: when red, green light；
Entrance valve position demarcation state: red light speed flash the fastest with green light；
Malfunction: red light and green light alternately flicker；
With reference to shown in Fig. 3, described guidance panel 6 is arranged over display screen 65, and described display screen 65 is positioned at described valve position and is opened to refer to
Show that, above lamp 63, this display screen is used for showing failure code；
In embodiments of the present invention, described motor driver 7 uses driving device for step-by-step；Described lower house 2 is internal to be set
Being equipped with supply unit 8, described supply unit 8 is positioned at described motor driver 7 side, and shown supply unit can be compatible
380VAC and 220VAC；The diameter of described output shaft 5 uses 35mm, 48mm or 60mm；Described upper encloser 1 and lower house 2 are all adopted
It is fabricated by with cast aluminium.
Operation principle:
The present invention propose a kind of auto-manual operation valve positioner, by the output shaft within the lower house of controller with hold
Row mechanism connects, and uses controller remotely or field control adjustment actuating mechanism, the most manually regulation and electric adjustable
Joint；By above-mentioned, handwheel by handwheel worm screw be connected with output shaft after Non-follow control actuator, guidance panel by with
Motor driver electrically connects thus is connected last Electronic control actuator with output shaft；
Guidance panel is connected last Electronic control actuator, mainly by electrically connecting with motor driver with output shaft
Comprise the following steps:
Need to check electrical connection, the position of special survey power selection switch before all electric operatings；Preset valve position eventually
End position, i.e. includes being opened to terminal location and closes to terminal location, sets valve position and is opened to display lamp display red colored lamp, valve position close to
Display lamp display green light, enters valve position below and demarcates state, below mainly complete from the most on-the-spot Electronic control of Electronic control on the spot
One-tenth corresponding steps:
Close to demarcating valve position process:
Rotation status selects knob select to O position i.e. valve position to demarcate state, and device enters valve position and demarcates state；
Press valve position to be opened to button and valve position and close to button and be held at more than 3 seconds simultaneously, until valve position be opened to display lamp and
Valve position is closed and is flashed to display lamp simultaneously；
Condition selecting knob is gone to LOCAL position, enters local controlled state, press valve position and close to button, electric manipulation valve
Door operating is to close to closing to terminal location；
Condition selecting knob is gone to O position, enters valve position and demarcate state, shake handwheel drive valve operating to the most required pass to
Terminal location；
Length is closed to button more than 3 seconds by valve position, makes the valve position of green close and is become long bright to display lamp from the state of flicker, and pass is to demarcation
Complete；
It is opened to demarcate valve position process:
Condition selecting knob is gone to O position, enters valve position and demarcate state；
Press valve position to be opened to button and valve position and close to button and be held at more than 3 seconds simultaneously, until valve position be opened to display lamp and
Valve position is closed and is flashed to display lamp simultaneously；
Condition selecting knob is gone to LOCAL position, enters local controlled state, press valve position and be opened to button, electric manipulation valve
Door operating is to close to being opened to terminal location；
Condition selecting knob going to O position, enters valve position and demarcate state, shake handwheel drives valve operating to required being opened to
Position；
Length is opened to button by valve position so that the red display lamp that is opened to is become long bright from the state of flicker, is opened to demarcation and completes.
Note: above required this position of terminal and closing of being opened to can independently set to terminal location, does not has sequencing；
Actuator can according to set be opened to and close to terminal location judge voluntarily to close rotation direction, it is not necessary to think setting.
On-the-spot electric operating: specifically include that
Condition selecting knob is reversed to " LOCAL " position；
Short being opened to button by valve position, actuator is electronic to be run to being opened to terminal location, unclamps button and i.e. stops；Length is opened by valve position
To button and keep 3 seconds, actuator transfers freeze mode to and runs, and after unclamping button, actuator proceeds to be opened to terminal
Position stop, if need midway stop, short by valve position close to button, in opening process, blinking red lamp, green light Chang Liang, arrival is opened
After opening position, red light Chang Liang, green light goes out；
Short by valve position close to button, actuator electronic to close to valve position terminal location run, unclamp button and i.e. stop；Length presses valve position
Closing to button and keep 3 seconds, actuator transfers freeze mode to and runs, and after unclamping button, actuator proceeds to close to end
End position stops, if needing midway to stop, short is opened to button by valve position, and in closing process, green light flashes, red light Chang Liang, arrives and closes
Closed position, green light Chang Liang, red light goes out；
If stopping at centre position, the equal Chang Liang of the reddest, green light.
Now, if needed when Electronic control is transformed into manual operation, only handwheel need to be shaken, it is not necessary to any cut
Change, Non-follow control actuator after being connected with output shaft by handwheel worm screw due to handwheel, and handwheel direction of rotation and output shaft
Rotation direction identical, i.e. handwheel turns clockwise, then corresponding output shaft turns clockwise, and handwheel rotates counterclockwise, then corresponding output
Axle rotates counterclockwise, and mainly by manual rotation's handwheel during practical operation, output shaft rotates then generation counterclockwise under normal circumstances
Table rotates to being opened to terminal location, and output shaft turns clockwise, and represents Xiang Guan and rotates to terminal location；
In like manner, when being transformed into Electronic control mode from manual manipulation mode, direct control operation panel is also had only to.
The above is only the preferred embodiment of the present invention, it should be pointed out that: those skilled in the art are come
Saying, under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, these improvements and modifications also should be regarded as
Protection scope of the present invention.
