Abstract

En kuleutforming for å motstå høye differensialtrykk uten lekkasje omfatter et sirkulært spor nær sirkelen for kontakt på ventilen med et omgivende sete. Høye differensialkrefter er overført utover sirkelen for kontakt slik at defleksjon på grunn av påført differensialtrykk resulterer i bøyning i sporarealet idet fullstendig periferisk setekontakt opprettholdes for å forhindre lekkasje.A ball design to withstand high differential pressure without leakage comprises a circular groove near the circle for contact on the valve with a surrounding seat. High differential forces are transmitted beyond the contact circle so that deflection due to applied differential pressure results in bending in the groove area while maintaining complete peripheral seat contact to prevent leakage.
