beg: Air separation cold box respirator structure
Thread Content
I have never seen the respirator of the air separation cold box. I heard that it is a two-way safety valve. Does anyone have a photo of the respirator or a structural description of the manufacturer? Thank you.
It should be a one-way safety valve, a flange cover with a shaft. It will open when overpressure occurs. When the pressure is low, it returns by gravity. There is a wire mesh in front to prevent the pearlescent sand from coming out or foreign matter from entering.
