Abstract
A steam trap for discharge of condensate is disclosed. The steam trap includes a chamber, a first orifice and at least one other orifice. Each of the orifices has closing elements. The closing elements of all orifices are connected to an interlinked lever arrangement operated by a float. The orifices open in response to level of condensate in the chamber of the trap.
Claims17
A steam trap comprising
- i. a chamber defining an enclosed space, inlet means for introducing condensate bearing steam in said space;
- an outlet means for condensate;
- ii. a first orifice leading to said outlet means for condensate;
- iii. at least one second orifice leading to said outlet means for condensate;
- iv. a first element to control the opening of said first orifice;
- V. at least one second element to control the opening of said at least one second orifice;
- vi a lever and link arrangement cooperating with said first element and said at least one second element;
- and
- v a float fitted to said lever and link arrangement adapted to be displaced in said enclosed space, in response to a level of condensate resident in said space, from a first position in which all orifices are shut to a second position in which the lever and link mechanism actuates the first element to uncover the first orifice and to a third and subsequent position in which first and at least one second orifice is uncovered for discharge of condensate selectively from only said first or first and second orifices.
