风门闭锁装置是防止井下风流短路,保证矿井通风系统稳定的重要措施〔1〕。针对矿井原有风门闭锁装置存在的问题和不足,研制出一种新型风门闭锁装置即圆盘复位式风门闭锁装置,与传统风门闭锁装置相比,具有漏风少、使用寿命长、成本低、安全可靠及应用范围广的优点,对提高矿井通风系统的可靠性起到重要的作用。 Damper locking device is to prevent short-circuit wind flow underground, mine ventilation system to ensure the stability of important measures 〔1〕. In view of the existing problems and deficiencies of the original damper closing device in the mine, a new type of damper closing device, ie the disc resetting damper closing device, has been developed. Compared with the conventional damper closing device, the invention has the advantages of less air leakage, long service life, low cost and safety Reliable and wide range of applications advantages, to improve the reliability of mine ventilation system plays an important role.
