Mine gas prevention prominent damper consists of two duplex throttle body and a set of pneumatic control system, each duplex damper body has a forward throttle and a reverse throttle the two duplex damper installed in the same contact Lane, There are two forward throttle, two reverse throttle. Equipped with automatic throttle control apparatus can realize the automation of the opening and closing of the damper. Economic Ninghao Bo mining mine sells a variety of doors, welcome new and old customers to inquire Haobo sincerely look forward to working with you! The main features compared with manual damper, in terms of product safety, ease of use, to achieve a greatly improved. 1, automatic control state, vehicles and personnel through the throttle open automatically, without effort required to open, convenient and practical. 2, between the two damper to achieve electrical and mechanical double locking, completely avoid the two doors are open at the same time, safe and reliable. 3, with manual control, using the remote controller or manual button artificially control the opening and closing of the damper. 4, each damper are made of anti-wind design, opening and closing the throttle in mine case of power failure can rely on human. 5, with emergency release latch function, special circumstances may be discharged by the two throttle lockout, the two sets of throttle all locked in the open position. 6, with both sound and light alarm mode. [Function] 1, automatic state two damper at both ends of the tunnel walls were installed infrared sensor test line formed at both ends of the damper, when pedestrians or vehicles enter the roadway either, sensors automatically detect and control equipment signal when A main entrance when someone passes the sensor signals, A main entrance of the power source is energized to open the A damper, the damper is equipped with a sensor detecting the closing of the damper, engagement state (this signal can be communicated to the ground control room, in order to easily detect the damper Close), anti-doors is generally normally open state. A door is open, the sound and light alarm device trigger signal alert warnings throttle open, pay attention to safety "and heritage red light flashes, the door B sound and light alarm device at the same time prompt" in front of the throttle open, you later "accompanied by red light. B door with a stopper (optional), depending on the installation conditions, in order to prevent both doors are open affecting the coal mine safety, a suitable delay (can be set according to need), the main entrance is automatically shut down, until the sensor detects closed in place, warning The voice and the red light turned off, the green light. A reverse throttle and B reverse damper is normally open. 2, the manual manual operation state, the tub when the throttle manually press the A door "open" control button, A door is opened, at the same time the door is closed B (lock optional), two doors open and close At the same time, the same with voice prompts signal. Similarly, pressing the A gate "off" control button, A door closed, while the B door open. 3, alarm status, throttle control to open or close the instruction issued by the control system, within 8 seconds (can be set) when the sensor is still not detected position signal, the control system will sound and light alarm monitor alarm instruction, sound and light The alarm display will be issued by the flashing red light signal and buzzer alarm signals to notify the relevant personnel to take measures. Technical parameters 1, the control part ◆ rated working voltage: AC127V, to allow voltage fluctuation range of 10% to 25%; ◆ Rated power: 40W; ◆ maximum DC operating voltage: DC24V; ◆ sound and light language speakers: Maximum working voltage: DC24V ; Rated Current: 500mA; sound loudness: 85dB; light visible distance: 80 meters; ◆ MagSwitch sensor: input voltage: 24 V DC; contacts rated load capacity: 0.1A to 1.2A; sensing distance of the sensor and the magnet 0 ~ 80mm. 2, the power section ◆ pneumatic power source: Input air pressure: 0.8 to 1.1 × 105 Pa; cylinder diameter: 100mm; minimum traction: 80 kg; ◆ electric power source: hydraulic station explosion-proof motor power: 1.5KW; hydraulic cylinder Thrust: 200kg; Operating voltage: 24 V DC; Working current: 35mA.
