Replacement and Application of Domestic Control Valve of Reforming Regenerative Unit
The original imported regeneration unit's lock hopper sequencing valve in the catalyst system has encountered various issues due to its extended usage period,including severe erosion and wear of the internal valve components,high cost,and long procurement cycles,which have adversely affected the safe operation of the plant.In response,a domestic substitution of the special valve for the lock hopper has been implemented.This article introduces the lock hopper's sequencing logic,the structure of the sequencing valve,the material and performance characteristics of the internal valve components,as well as the domestic substitution plan.The domestic substitution of the lock hopper sequencing valve effectively resolves issues such as long procurement cycles,high costs,and ensuring long-term safe operation.
