Air locker is mainly used in flue damper systems to prevent coal powder or dust grains flowing from one part to another under pressure, and to maintain the coal powder grain flowing smoothly. We manufacture the equipments strictly abiding by standard drawings of Water & Elastic Ministry<<74 Flue Dam-per Typical Design Standard.We have made great improvement for the designing of air locker in pipeline standard 74 and 64. When the conical air locker works normally, the flow of grains will continuously keep on running.Sloping air locker used in coarse pulverized coal separator, which is located on coal recycling pipe. Its diameter is same as that of the pipe.There are Dg200、250、300、400、500, totally 5 kinds of conical air locker according to its specifications.
