Abstract
A steam trap includes a body having a flow passageway therethrough between an inlet connectable to a steam pipeline and an outlet connectable to a condensate drain line. The flow passageway has a first flow restriction defined by a first venturi orifice to pass condensate therethrough while restricting the flow of live steam, and a second flow restriction, downstream of the first flow restriction. The second flow restriction is adapted to allow condensate flow therethrough while restricting the flow of flash steam.
Claims12
A steam trap comprising:
- a body having a flow passageway therethrough, said flow passageway extending between an inlet connectable to a steam pipeline and an outlet connectable to a condensate drain line, said flow passageway comprising:
- a first flow restriction defined by a first venturi orifice configured to pass condensate therethrough while restricting a flow of live steam;
- and
- a second flow restriction, downstream of said first flow restriction, said second flow restriction defining a second venturi orifice configured to allow condensate flow therethrough while restricting a flow of flash steam;
- wherein said first and second venturi orifices are arranged orthogonally to one another and said first and second venturi orifices are arranged in series.
