CONDENSATE TRAPS

摘要

A condensate trap comprises an inlet (6) and an outlet (8), and a valve (14, 40) which opens to allow discharge of condensate but closes to prevent the discharge of vapour (such as steam). The flow path between the inlet (6) and the outlet (8) includes a swirl duct (30). Vapour leaking past the valve (40) generates a vortex within the swirl duct (30) which restricts vapour flow through an exit passage (36). Consequently, leakage of vapour is restricted, even if the valve (40) fails in an open condition.
