Mine damper manufacturer Jinan Dongshan Mine Equipment Co., Ltd. (0531-89004695) R & D, production and sales, maintenance mine dampers, automatic balance without pressure damper, throttle manually without pressure, without pressure damper automatic electric, pneumatic automatic non-pressure damper, waterproof fire closed doors, impact Bomi closed throttle valve and other kinds of mining, since the establishment of its establishment to put product quality as life, strict quality control, and resolutely put an end to substandard products to the market . Mine damper is very important the mine ventilation facilities, small series to tell something about the knowledge of mine adjust throttle hope for your help. First, the mine action damper damper mining ----- manually controlled by a mechanical transmission changing windscreen is turned on, thereby changing the ventilation area, to control the ventilation flow purposes. Second, the technical characteristics of the damper mine which ----- 1, the modular structure, easy installation, removal and transport, reusable; 2, simple operation, convenient; 3, can be flexibly adjusted according to the demand size of the wind . 4, the use of composite materials and fiberglass coated, flame retardant, corrosion, moisture; 5, product series, to meet the different needs and pedestrian tunnel ventilation; 6, the production process in line with relevant industry standards. Mine after three, matching mine automatic throttle control device (electro-pneumatic throttle control devices, Pneumatic throttle automatic control device, automatic electric throttle control device, etc.) with a damper having a damper automatically open and close, electrical locking function, downhole throttle automated control, to solve the pedestrians, traffic, throttle manual switch, extraordinary inconvenient transportation and other issues. Effectively preventing the occurrence of accidents throttle assault. Since the throttle opening and closing time is adjustable, adjustable speed, effectively preventing the throttle more damage, reduce labor intensity, increase productivity, reduce production costs and ensure safety in production, which has the following characteristics ----- (1) Every throttle adopt the anti-wind design to ensure that the situation in the mine can rely on human power opening and closing the throttle. (2) be achieved between two damper electrical and mechanical double locking, completely avoid the situation that both doors were open, safe and reliable. (3) with manual control function, you can use * or manual button to artificially control the opening and closing the damper. (4) under automatic control state, vehicles and personnel through the damper automatically open, vehicle or person automatically shut down after, no manpower to open, convenient and practical (5) with emergency unblocking function, under special circumstances, can lift two damper closed, so that the two sets of throttle all locked in the open state. (6) with LED display alarm and voice alarm two alarm mode, when the vehicle passes, may issue a variety of voice prompts signals a fault condition can be audible and visual alarm signal to your needs, our insistence; your satisfaction, our pursuit!
