US 5,123,452 A · Flow constriction device for removal of condensate

Abstract

A flow constriction device for the complete removal of condensate from steam and compressed air lines and steam-using equipment. This device incorporates the insertion of a uniquely designed convergent/divergent nozzle into a body piece. The body piece is installed within the piping system using existing means. The nozzle is protected from blockage with a screen secured at the inlet of the body piece. The dimensions of the convergent/divergent flow channel are determined for each application taking into account factors of pressure differential and the flow rate of the condensate to be removed. The design of the assembly allows for easy interchanging of the nozzle piece to meet changes in system conditions. The body of the device can be reused, and the nozzle piece can be changed without disturbing the in-line screen element.

Dependent claims

A flow constriction device for the extraction of condensate from a steam and compressed air line into a condensate line, the device comprising:

an outer body having an inlet bore with a first diameter and an outlet bore with a second diameter greater than the first diameter, the inlet bore meeting the outlet bore at a shoulder inside the outer body and the inlet bore being internally threaded adjacent to the shoulder;
means for connecting the steam and compressed air line to the inlet bore;
means for connecting the condensate line to the outlet bore;
a filter screen mounted in said inlet bore;
a nozzle having a flat head and an externally-threaded cylindrical body having a turbulence producing inlet portion with a third diameter, a cylindrical venturi channel having a fourth diameter less than the third diameter and a turbulence-reducing outlet portion having a fifth diameter greater than the fourth diameter, the nozzle head being shaped so that it can be engaged by a wrench inserted through the outlet bore passage so that the nozzle body can be threaded into the inlet bore to draw the head against the shoulder.
