US 2019/0064856 A1 · Hybrid Flow and Pressure Regulation

Abstract

A hybrid pressure and flowguage regulator apparatus includes a regulator body, an inlet, and an outlet assembly. The outlet assembly includes a first orifice of a first size, a second orifice of a second size that is larger than the first size, and a mechanism that automatically moves the first orifice between a first position and a second position. When the first orifice is in the first position, the flow of gas passes through both the first orifice and second orifice. When the first orifice is in the second position, the flow of gas bypasses the first orifice and flows through the second orifice with a specific flow rate or a second pressure that is less than the first pressure. The apparatus may also include a gauge that provides a visual indication of both the specific flow rate and the second pressure.

Dependent claims

An apparatus, comprising:

a regulator body;
an inlet configured to introduce a flow of gas into the regulator body under a first pressure;
and
an outlet assembly that directs the flow of gas from the regulator body into a downstream gas line, the outlet assembly comprising:
a first orifice of a first size;
a second orifice of a second size that is larger than the first size;
and
a mechanism that automatically moves the first orifice between two distinct positions:
a first position wherein the flow of gas passes through both the first orifice and second orifice to the downstream gas line;
and
a second position wherein the flow of gas bypasses the first orifice and flows through the second orifice to the downstream gas line with a specific flow rate or a second pressure that is less than the first pressure.
