Urumqi two-way pneumatic pressure free damper automatic control device for mine damper

Urumqi two-way pneumatic pressure free air door - automatic control device for mine air door 1. A door sound box; 2. A Door control box; 3. A door magnetic control valve; 4. A Door actuator; 5. Interlocking control box; 6. B Door actuator; 7. B door magnetic control valve; 8. B Door control box; 9. B Door sound box; 10. A gate generator; 11. A Door; 12. B door; 13. B gate generator; 14. Air source treatment box; 15. A door permanent magnet; 16. B Door permanent magnet. The door a control box and door b control box are respectively connected with a door sound box, b door sound box, a door sound box The door b sound box is an air source horn, which is also powered by the air source. The door a magnetic control valve and the door b magnetic control valve output the door a and door b opening and closing states through the departure and closeness of the corresponding door a permanent magnet and door b permanent magnet. When door a or door b is opened, the sound output of the air door is achieved.

Two way pneumatic pressure free air valve When the device is in the state of air stop, the actuator of valve a and valve b are automatically in the state of automatic exhaust, and valve a and valve b can be opened and closed manually. The working pressure of the air source in the air source processing box is 0.3-0.8mpa. When the device is in the state of gas stop, valve actuator 4 and valve actuator 6 are automatically in the state of automatic exhaust, and valve 11 and valve 12 can be opened and closed manually. The main performance characteristics of zmk127 mine automatic control damper, a kind of mine hydraulic damper control device that belongs to the mine comparison. 1. The device is automatically controlled by plc, uses infrared sensor as a device, and has both language, so that pedestrians and vehicles can pass through smoothly and safely. 2. Control function: after receiving the infrared sensor, the controller will control the cylinder and oil cylinder of the actuator and open the air valve; 7 seconds later, it can be adjusted by plc to automatically control the actuator and close the damper.

Two way pneumatic pressure free damper Performance characteristics

1. The device is automatically controlled by plc, uses infrared sensor as a device, and has language, so pedestrians and vehicles can pass smoothly and safely.

2. Control function: after receiving the infrared sensor, the controller will control the cylinder and oil cylinder of the actuator and open the air valve; 7 seconds later, it can be adjusted by plc to automatically control the actuator and close the damper.

3. Locking function: when any one of the two interlocked air valves is opened, the controller controls the actuator to lock the other air valve so that it cannot be opened; When the opening damper is closed, the controller will automatically unlock.

4. Manual unlocking function: when a fault occurs, press the reset button, the whole control stops working, and the damper can be pushed open manually. After troubleshooting, press the set button, and the control will resume normal operation.

5. Prompt function: when the damper is opened, the controller shall control the sound light box prompt.

Compared with the electric control damper control device, the electric control damper control device and the electric control damper control device, the two-way pneumatic pressure free damper control device uses compressed air as the power source, without any electrical connection, and does not use power to realize automatic control of the damper. It has higher safety performance, higher degree of automation, saves manpower, and can achieve mutual locking of the two dampers, It is safe to avoid simultaneous opening of two air doors. The pneumatic pressure free air valve can be opened and closed synchronously in different directions, and the use of a chain bar balance mechanism makes the opening of the air valve labor-saving, convenient and flexible. No manual operation is required for the air door: the air door adopts the infrared sensing principle, and when a person or a vehicle reverses, it is sent to the host through infrared detection to achieve the purpose of opening the door. It is convenient without manual operation. The exclusive function of the air door can be used with more confidence: when people or vehicles pass through, the device in the air door plays a warning role, and there is no need to open the door in the opposite direction. It is safe. At present, the air door control in domestic coal mines includes: manual control of door leaf opening and closing and mechanical locking. Its disadvantage is the labor intensity of workers. Some automatic controls in the market are also based on electricity. The use of electric infrared induction devices is collected and output to the control host, which is also based on power supply, The main engine outputs the switch of the electric control solenoid valve to further control the hydraulic or pneumatic drive,.
