Main Features and Applications

With the improvement of coal mine automation level, manual valves are difficult to adapt to the needs of modern development, and electric valves are widely used in newly designed mines or the renovation of old mines. Our company's mining explosion-proof valve electric device is specially developed to improve the automation system of coal mine valves, and the KXBC explosion-proof valve electric device control box is a control product that is matched with the mining explosion-proof valve electric device.
The KXBC mining explosion-proof valve electric device control box has the function of connecting with the DCS system interface, making the application of the control box in automation systems more extensive and reliable. On this basis, the control box has functions such as short circuit protection, overload protection, undervoltage protection, leakage protection, over torque protection, phase failure protection, and automatic correction of phase sequence identification. It also has switching functions for stroke control and remote/local control, making its practical functions more complete.
The exterior design of the KXBC mining explosion-proof valve electric device control box not only ensures explosion-proof performance, but also has mechanical and electrical interlocking functions to prevent misoperation, making the equipment safe and reliable to use. On this basis, in order to monitor the operation of the equipment, this product also sets various operation monitoring indicators, such as power indicator, valve opening indicator, valve closing indicator, over torque indicator, fault indicator, and valve position opening display.

Technical Performance of Control Box

1. The control box has multiple protection functions such as short circuit, phase failure, overload, etc.
2. There is a switch stop button, on-site/remote switch, LCD display valve opening and status output switch in place signal, fault signal, remote control signal, and 4-20mA valve position feedback signal to the remote control box.
3. Signal level (DC): 5V, 24V
4. Output impedance ≤ 700 Ω
5. Output maximum signal current DC36 mA
6. After the motor rotation direction is determined, the phase sequence of the three-phase power supply can be automatically corrected, and users can freely connect to the three-phase power supply of the electric control box.
7. The control mode can be selected by the dip switch:
(1) Conventional control mode: jog mode; Or maintain the way.
(2) Two line control mode: with signal on/without signal off; Or there may be a barrier or no barrier,
8. Adopting a quick opening door structure and a modular internal circuit structure, it is convenient for on-site maintenance and repair.
9. Can be reliably connected to various self-control systems:
(1) Provide dry contacts by the user and use the+24 VDC power supply on the module.
(2) The user provides a+24VDC power supply, and at this time, the negative pole of the user's+24 VDC power supply is connected in parallel with the negative pole of the module power supply. The positive pole of the power supply is connected
By entering each functional end of the module, various control functions can be achieved.
10. Both input and output signals are optically isolated, with strong anti-interference ability.
11. Valve opening, closing, electronic interlocking, and mechanical interlocking ensure that the open and closed AC contactors cannot be simultaneously closed.
The undervoltage protection value is negative 15% of the rated voltage.
13. It can be configured for bus communication such as MOdbus and Profibus, with a 485 bus interface to achieve data communication.
