4. do not possess the interface function that is connected with PLC;
5. all adopt analog circut, the overall volume of entire controller is too huge, and it is bigger to take the space of instrument panel (cabinet).
Summary of the invention
The purpose of the utility model is to provide a kind of electric valve control panel, is intended to solve the aperture indication that has the control panel existence now and adopts simulated pointer to represent that precision is not high; Valve leaves, valve closes, moment/states such as protection are indicated poor stability with light emitting diode; Open operations such as valve, pass valve and adopt the button form, volume is big and reliability is not high; Do not possess the interface function that is connected with PLC; The entire controller overall volume is too huge, takies problems such as the space of instrument panel is bigger.
The utility model is achieved in that a kind of electric valve control panel, is provided with control terminal and tenminal block, also is provided with on this control panel:
Be used to show that the LED of electric valve running state shows indicating device;
Be used to control the control button of electric valve running state; And
Be used to connect the PLC interface of upper-position unit.
Further, said LED shows that indicating device comprises digital aperture indication, " valve leaves " tutorial light, " valve pass " tutorial light, " moment/protection " tutorial light, " on-the-spot/control far away " tutorial light.
Further, said control button comprises " conversion " button, " pass valve " button, " stopping " button, " driving valve " button.
The electric valve control panel that the utility model provides has solved the not high defective of simulated pointer precision, uses the indication of digital aperture, and is clear and intuitive and precision is high; Valve leaves, valve closes, moment/states such as protection show the replacement light emitting diode with LED, and stability better; Open and close are adopted acoustooptic alarm to haveing force moment protection and accident (motor overcurrent, motor overheating, stall etc.) protection, and are more safe and reliable; Open and close working procedure flash of light prompting; Upper-position unit (computer etc.) can pass through the PLC interface, with the Push And Release of position formula control electric valve.

Embodiment
For the purpose, technological scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Fig. 1, Fig. 2 show the structure of the electric valve control panel that the utility model embodiment provides.For the ease of explanation, only show the part relevant with the utility model embodiment.
This control panel is provided with five kinds of state LED demonstration indicating devices such as digital aperture indication 1, " valve leaves " tutorial light 2, " moment/protection " tutorial light 3, " valve passs " tutorial light 4, " on-the-spot/control far away " tutorial light 5, has four kinds of " driving valve " button 9, " pass valve " button 7, " stopping " button 8, " conversion " buttons 6 etc. to control button; Also has a PLC interface 10.In addition, this control panel also is provided with electrical source of power tenminal block A, B, C, N, U, V, W and control terminal 1～17.
Debugged under the prerequisite that finishes and can proper functioning at the Electric actuator mechanical part of electric valve; The terminal of control terminal and Electric actuator is coupled together; The three-phase electrical source of power is received respectively on A, B, C, the N tenminal block, and tenminal block U, V, W receive on the motor terminal of Electric actuator; Whether energized, inspection controller are arranged on " scene " state (" on-the-spot/control far away " tutorial light 5 is bright), if not, press " conversion " button 6 controllers and be set to " scene " state.With the Electric actuator handwheel electric valve is opened into and is about 50% aperture, at this moment, can drive valve, close operations such as valve electric valve.Press " driving valve " button 9 when controller is switched on for the first time, the Electric actuator operation has two kinds of possibilities: a kind of possibly be that " valve leaves " tutorial light 2 is glittering by the correct direction operation, and Electric actuator is opened to operation and stopped " valve leaves " tutorial light 2 Chang Liang until fully open position.Numeral aperture indication 1 is automatically made 100%.Press " pass valve " button 7, Electric actuator closes to operation, and " valve pass " tutorial light 4 is glittering, and Electric actuator closes to operation and stops " valve pass " tutorial light 4 Chang Liang until the complete shut-down position.Numeral aperture indication 1 is automatically made 0%.Another kind possibly be Electric actuator by wrong direction operation, though " valve leaves " tutorial light 2 is glittering, Electric actuator close to the operation stop until the complete shut-down position; " valve pass " tutorial light 4 Chang Liang, digital aperture indication 1 is automatically made 0%, and the automatic logic calibration power supply of controller this moment phase sequence is after 3 seconds; Electric actuator will be opened to operation from trend; " valve leaves " tutorial light 2 is glittering, and Electric actuator is opened to operation and stopped " valve leaves " tutorial light 2 Chang Liang until fully open position.Numeral aperture indication 1 is automatically made 100%.Press " pass valve " button 7 when controller is switched on for the first time, the Electric actuator operation process is the same, and just traffic direction is opposite, and so far, the installation of controller and Electric actuator, debugging finish; Electric actuator open to or close in service, press " stopping " button 8, Electric actuator will stop at this present position.When the Electric actuator state of rest, pressing this key is noise reduction;
As press " conversion " button 6 controllers and be set to " far away control " working state, can realize the automatic control of computer PLC through the PLC interface on the controller 10 to Electric actuator.
The control panel that the utility model embodiment provides has solved the not high defective of simulated pointer precision, uses the indication of digital aperture, and is clear and intuitive and precision is high; Valve leaves, valve closes, moment/states such as protection show the replacement light emitting diode with LED, and stability better; Open and close are adopted acoustooptic alarm to haveing force moment protection and accident (motor overcurrent, motor overheating, stall etc.) protection, and are more safe and reliable; Open and close working procedure flash of light prompting; The automatic logic of power phase is proofreaied and correct; Upper-position unit (computer etc.) can pass through the PLC interface, with the Push And Release of position formula control electric valve.
