介绍了紧急切断阀的结构特征、工作原理及其特点。该阀的优点突出,是高炉煤气余压透平发电装置的关键设备。当情况异常时,该紧急切断阀能在0.5s左右切断大管道煤气,保证高炉安全生产和透平发电机安全。
The structural characteristics, working principle and characteristics of the emergency shut-off valve are introduced. The outstanding advantages of the valve, blast furnace gas pressure turbine power plant is the key equipment. When the situation is abnormal, the emergency shut-off valve can cut off the large pipeline gas at about 0.5s to ensure the safe production of the blast furnace and the safety of the turbine generator.
