Abstract

A condensate discharge device which prevents metal ions from attaching and depositing on the condensate discharge port surface. An inlet, a condensate discharge port, and an outlet are formed in a valve casing, which valve casing includes an upper casing and a lower casing. A valve seat member having a discharge passage is screwed into the lower casing. The discharge passage includes a first orifice having a smaller opening area than the condensate discharge port, and a second orifice having a smaller opening area than the first orifice. A movable member is mounted through the second orifice. On end of the movable member rests on one side of the second orifice, and another end is located on the other side of the second orifice. Condensate flows slowly through the condensate discharge port, preventing metal ions from attaching there, and flows rapidly through the second orifice. Any metal ions attaching to the second orifice are removed by moving action of the movable member, which moving action is caused by flow of condensate around the movable member.
