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.
Claims13
A steam trap comprising:
- i. a chamber defining an enclosed space, inlet means for introducing condensate bearing steam in said space, and an outlet means for condensate;
- ii. a first orifice leading to said outlet means for the condensate;
- iii. at least one second orifice leading to said outlet means for the 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;
- vii. a float fitted to said lever and link arrangement 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 the first and at least one second orifice is uncovered for discharge of the condensate selectively from only said first or first and second orifices;
- and
- viii. a resilient element provided between said lever and link arrangement and said second element to damp the uncovering and shutting of said second orifice.
