Abstract
This paper was analyzed for a sealing characteristics of single lip contact type o-ring and multiple lip contact type packing for a swivel joint using the finite element method. According to the FE analysis, a conventional o-ring produces a maximum contact normal stress of 2.5MPa for a supplied LP gas pressure of 1.8MPa, which is related to the sealing performance. But, a sealing performance of newly invented multi-lip packing produces a maximum contact normal stress of 3.01MPa, which is 20.4% higher than that of a conventional o-ring. And an extrusion of a conventional o-ring, which is strongly related to the sealing endurance safety, was occurred at a supplied gas pressure of 1.62MPa. But, a multi-lip packing does not produce up to the gas pressure of 1.8MPa. This means that a new type of multi-lip packing may have excellent sealing characteristics because of no extrusion for high gas pressure. Thus, multi-lip packing with multiple lip contacts may be useful for high sealing and endurance safety compared to that of the conventional o-ring with a single lip contact.
