| 摘 要： | 介绍了 CJK－ 200型自动抽排切换器的研究试制情况。试验表明，该产品可根据瓦斯抽放浓度对抽放管道的流向、抽放与排放状态进行自动控制与切换。可在不使系统浓度低于设定值、保证排放口安全的条件下，实现采空区瓦斯浓度低时能连续强化抽放、浓度高时又能使抽放瓦斯进入矿井抽放系统。

Development and Application of Model CJK Automatic Suction and Discharge Changer |
| |
| Abstract: | The paper describes the development and tests of Model CJK－ 200 automatic suction and discharge changer. The tests show that this changer can automatically control and change the flow direction of gas in the pipeline and suction and discharge state according to gas concentration. Under the conditions of gas concentration in suction system not less than the preset value and guaranteeing safety at discharge outlet, it can not only realize the continuously intensive suction of low－ concentration gas from gob, but also make the high－ concentration gas enter mine gas drainage system. |
