Fluid regulator having a retractable sense tube
Abstract:
A fluid regulating device includes a valve body having an inlet, an outlet, and a valve port, a control element adapted to be displaced relative to the valve port to control the flow of a fluid between the inlet and the outlet, a control assembly operatively coupled to the control element and including a diaphragm disposed adjacent a diaphragm chamber, and a sense tube. The sense tube has a first end, a second end, and a sense hole formed adjacent the second end. The first end is positioned to communicate with the diaphragm chamber, and the second end is disposed adjacent the outlet, with the second end being movable, relative to the first end, between a first position within the valve body and a second position extending outside of the valve body, the movement being in response to fluid flowing between the inlet and the outlet.
