Abstract
An intelligent electric valve repair tester. The problem that the existing electric valve test mode is long in operation time and whether feedback signals exist in the field application process cannot be determined can be solved. The touch screen comprises a rechargeable power supply, wherein the output end of the rechargeable power supply is respectively connected with the touch screen and the power supply input end of a main controller, and the data transmission end of the touch screen is connected with the main controller; the terminal signal transmission end of the main controller is connected with the input and output terminal, the control output end of the main controller is connected with the stepping motor controller, and the output end of the stepping motor controller is connected with the stepping motor. Manual operation is replaced; the valve position feedback signal terminal of the electric valve feeds back signals to the tester, the current signal feedback current is displayed on the touch screen, and whether the circuit board of the electric valve is successfully repaired is determined through the valve position opening degree and the feedback signal value of the electric valve. Simple and novel structure, easy operation, convenient to use and test precision height, practicality are strong.
Description
Technical field
The utility model belongs to application of electronic technology field, is related to a kind of tester, and especially a kind of motor-driven valve reparation is surveyed
Try instrument, specifically a kind of intelligent dynamoelectric valve recovery test instrument.
Background technique
Common motor-driven valve test mode be motor-driven valve circuit board repair after, need to adjust motor-driven valve aperture percentage and
Pass degree percentage, rotates the code switch on circuit board by hand, shows that percentage is true on motor-driven valve circuit board LCD screen
Determine valve opening；When not showing aperture on motor-driven valve circuit board LCD screen, then need to rotate by hand the several hundred circles of code switch even
Thousands of circles could show valve opening, this takes a long time operation；Additionally due to this manual operation only can determine that valve opening, and
When motor-driven valve after maintenance is tested with the method, 4 ~ 20mA feedback signal of valve position is unable to test out, so that this
When kind test mode not can determine that field application, if having feedback signal.
Summary of the invention
It takes a long time to solve the operation of existing motor-driven valve test mode and not can determine that when field application whether have
The problem of feedback signal, the utility model proposes motor-driven valve surveys a kind of easy to operate, easy to use and that accurate testing degree is high
Instrument is tried, specific technical solution is as follows:
A kind of intelligent dynamoelectric valve recovery test instrument, including rechargable power supplies, the output end of the rechargable power supplies respectively with
The connection of the energization input of touch screen and master controller, the data transmission terminal of the touch screen are connected with the master controller；
The terminal signals transmission end of the master controller is connected with input and output terminal, the control output end of the master controller and step
It is connected into electric machine controller, the output end of the controllor for step-by-step motor is connect with stepper motor.
The utility model has the beneficial effects that input and output terminal is connected with motor-driven valve circuit board code switch when use
It connects, the direction to be rotated according to motor-driven valve, the increment or decrement of code switch, the stepping of recovery test instrument is set on the touchscreen
Motor rotation, motor-driven valve are passed through three phase mains, the aperture of valve are shown on the LCD screen of motor-driven valve, instead of manual operations；
The feedback signal of tester input and output terminal, motor-driven valve work are given using the valve position feedback signal terminal of motor-driven valve simultaneously
When, current signal feedback current is shown on the touchscreen, when the 100% of motor-driven valve closes, valve position feedback exports 20mA signal,
Valve position feedback exports 4mA signal when motor-driven valve 100% is opened, and determines electricity by the valve seat opening and feedback signal value of motor-driven valve
Whether the circuit board reparation of dynamic valve succeeds.Structure is simple and novel, easy to operate, easy to use and accurate testing degree is high, practicability
By force.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1- master controller, 2- touch screen, 3- controllor for step-by-step motor, 4- stepper motor, 5 rechargable power supplies, 6- are defeated
Enter output terminal.
Specific embodiment
In order to make it easy to understand, being made further instructions below with reference to Fig. 1 to the utility model:
Embodiment 1: a kind of intelligent dynamoelectric valve recovery test instrument, including rechargable power supplies 5 provide electric power for integral device,
In the case where being can be used normally in the case where there is external power supply simultaneously without external power supply still using its chargeable characteristic
It can be used；The output end of the rechargable power supplies 5 is connect with the energization input of touch screen 2 and master controller 1 respectively, described
The data transmission terminal of touch screen 2 is connected with the master controller 1, using keyboard and display and master in practice process
Controller 1 connects, and display shows data, and keyboard data accordingly controls information, but due to carrying not more than component and connection is cumbersome
Just, it surveys and display and keyboard is replaced with into touch screen 2, in order to operate；The terminal signals transmission end of the master controller 1 with it is defeated
Enter output terminal 6 to be connected, for being transmitted with motor-driven valve signal data, the control output end of the master controller 1 and stepping electricity
Machine controller 3 connect, for signal convert and control controllor for step-by-step motor 3, the output end of the controllor for step-by-step motor 3 with
Stepper motor 4 connects, whether for controlling the operation of stepper motor 4.
The utility model has the advantages that structure is simple and novel, easy to operate, easy to use and accurate testing degree is high, practical.Effectively
It solves existing motor-driven valve test mode operation to take a long time and not can determine that when field application whether there is feedback signal
Problem.
