DKX drawer control box
The specifications of DKX electric valve control box are as follows: general type, outdoor type, adjustable type and explosion-proof type.
The characteristics of DKX electric valve control box:
1. The control circuit adopts DC regulated power supply, which has reliable control, accurate opening indication and safe operation.
2. The chassis adopts standard instrument chassis, which is small in size and light in weight. It is easy to install on the control panel. The buzzer alarms when the output torque of the electric valve, so as to eliminate the malfunction in time.
Overview of DKX electric valve control box:
DKX control box is an electronic control box matched with DZ, DQ and DDQ stacked valve electric devices. It is suitable for controlling the opening and closing of electric valves. It can realize the control of electric valves over a long distance in the control room. The control box is widely used in water supply and drainage, heating and power plants using pipeline valves after matching with electric valves. Chemical industry, food industry, textile industry, paper industry, pharmaceutical industry, shipping industry, steel industry and coal industry.
4. The working principle of DKX electric valve control box:
The circuit of the control box is mainly composed of four parts: the control circuit, the working display circuit, the opening indicator circuit and the main circuit (the stroke and moment micro-switch KXK, GXK, KZK, GZK and the motor in the valve electric device). When the power of the control box is connected, the power indicator lights up, the field/remote control indicator lights green, and the control box is in the remote control state. When the valve is in the "full open" position, the green indicator on the panel is on, the yellow indicator on the "full close" position is on, and neither indicator is on when the valve is between the "full open" position and the "full close" position. The "field/remote control" button is the field/remote control selection key, which is released into the remote control status indicator to show green. Press to show the red light for the on-site status indicator. When the control box is selected as the remote control state, the buttons such as "open valve", "close valve" and "stop" on the panel of the control box play a controlling role. The "on-site" and "off-site" buttons on the field electric devices do not work (when the users choose the electric devices, the on-site control buttons are optional, so some users'electric devices may not have the on-site control function, but the absence of the on-site control function does not affect the remote control function of the control box. When choosing the control box as the on-site state, the buttons of "on-site opening" and "off-site" on the electric device play a controlling role, while the buttons of "on-site opening", "off-site closing" and "stop" on the panel of the control box do not work. Press the "open valve" button, the power supply of the motor is connected, the motor rotates. When the valve reaches the "full open" position, the 1GXK micro-switch is touched by the cam, and the motor stops turning. At the same time, the 2GXK micro-switch is touched by another cam, indicating that the yellow indicator light of the "valve switch" is on. When the electric valve needs to stop in the course of opening or closing, the "stop" button can be pressed. In the process of opening or closing the electric valve, if there is an "over-torque" situation, the cam of the electric device will touch one of the two micro-switches KZK or GZK. The motor will stop turning and turn on the alarm circuit. The red fault indicator light on the panel is on, and the buzzer will emit a 4 KHz alarm sound.
Installation and commissioning of DKX electric valve control box:
Install and fix it according to the model specifications you choose. Connect the terminal of the control box and the electric device with the same terminal number of the cable. If the electric devices ordered by users do not have field control buttons, 12, 13 and 14 will not be connected, which will not affect the "remote control" function of the control box. Connect three-phase power supply to terminals A, B, C and N of control box respectively. After confirming the connection is correct, turn on the power switch on the panel and check whether the control box works in the "remote control" state. If it is not "remote" state, please set it to "remote control" state. When the electric valve is opened to about 50% by hand wheel, press the "on" or "off" button to check whether the direction of the valve is the same as that of the button pressed. If not, press "stop" immediately, cut off the power supply and replace the two phases in the three-phase power supply. Press "on", "off" and "stop" buttons respectively to check whether the work is normal. When the valve is in the "full open" position, check whether the opening meter pointer indicates 100% calibration. If there are errors, please fine-tune the opening on the front panel so that the opening meter indicates 100%. (When the machine is out of the factory, it has been adjusted near the optimal position, and users need not make big adjustments.)
