Austenitic Stainless Steel Four-Way Valve S Receiver Cracking Failure Analysis and Countermeasures
Four-way valve is the core component of refrigeration equipment,and its reliability directly affects the service life of the product.This paper focuses on the cracking failure sample of the S receiver of the four-way valve,through metallographic analysis,material composition testing,scanning electron microscopy,and energy spectrum analysis,combined with relevant literature on the causes and mechanisms of cracking of the S receiver flare,and concludes that the cracking failure mechanism of the S receiver is"copper brittleness"and puts forward the corresponding solution measures.
