<p>PURPOSE: To prevent generation of droplets due to condensation by installing a specified number of stages so as to regulate each pressure drop, and providing a critical orifice to restrict momentary drop of temperature. CONSTITUTION: A highly compressed gas flows through a conduit 1 and orifice 2, and an expansion jet stream 4 flows through a first expansion chamber 3. The first expansion chamber 3 has an outlet 7 connected with a pressure regulating valve 10 through a conduit 8 wherein the pressure regulating valve 10 is made a critical orifice. Part of the expansion jet stream 4 flows into the conduit 5 through the inlet 6, reaches a second critical orifice 11, and is expanded inside a second expansion chamber 12 from the intermediate pressure to a low pressure.</p> |
