Abstract

An offset steam trap is designed for removing condensed water from a horizontal steam pipe to which the trap is connected. The body of the trap contains a ball valve for permitting limited water flow out of the pipe through an orifice, and the body has an offset portion between its inlet and the orifice. The body is installed with the orifice parallel to but below the center line of the pipe, so that water will not collect in the bottom of the pipe below the level of the orifice.

Claims

1. An offset steam trap for removing condensed water from a horizontal steam pipe having an interior and an end to which the trap is connected, said trap comprising

a hollow body having an inlet adapted to be joined to said pipe end,

a primary outlet offset downwardly from said inlet and parallel thereto, and

an orifice installed in said primary outlet for permitting limited water flow out of said pipe through the orifice,

said orifice having an axis below the bottom of the pipe interior, so that water may escape from the bottom of the pipe interior.
