一. 防爆矿用煤安闸阀用途： 
安装在水、汽管道上作为启闭装置用。 
二. 防爆矿用煤安闸阀结构特点： 
1. 阀门采用压力自紧式密封结构，阀体、阀盖法兰连接。 
2. 阀瓣采用双闸板中间万向顶结构，能自动调整阀瓣与阀座密封面吻合度，保证阀门的密封。同时此
结构维修方便，节约费用。 
3. 阀瓣、阀座密封面用钴铬钨硬质合金由等离子喷焊而成，密封面硬度高，耐磨擦，抗擦伤，使用寿
命长。 
4. 阀杆用渗氮钢制成，表面氮化处理，硬度高，抗擦伤，耐腐蚀，使用寿命长。 
5. 阀门的开关由电动装置来控制，电动装置配有转矩控制机构、现场操作机构和手、电动切换机构。
除就地操作外，还可以进行远距离操作。 
三. 注意事项： 
1. 阀门尽可能垂直安装，阀杆向上。介质流向可以从任何一侧进入（DN300.PN32 除外）。 
2. 阀门可安装在管道的任何位置，同时根据介质和介质的温度选择碳钢或合金钢阀门。
