One-way check valve
Thread Content
Is the function of the one-way check valve at the main fan outlet to prevent backflow?
Well, the main air valve closes automatically to prevent the catalyst carried by the main air from flowing back into the compressor inlet. This post was last edited by jevy on 2009-4-10 at 13:52.]
It provides one-way protection to prevent the catalyst from flowing back in case of a shutdown of the main air supply; it is a safety device
Yes, if the main fan stops operating due to an accident, the one-way damping valve can close quickly to prevent the catalyst from flowing back into the main fan or the booster, thereby avoiding damage to the equipment.
It seems you’re not involved in catalysis work. Anyone working in this field should know that its function is to act as a pipe during normal operation; in the event of an accident, it shuts itself off to prevent the catalyst from flowing back into the main fan and damaging it
It’s to prevent backflow, especially when there is a catalyst present
Prevent the catalyst from flowing back into the main fan.
