FLUID REGULATOR HAVING A BIASED PRESSURE SENSE TUBE

摘要

A fluid regulating device includes a valve body, a control element, a control assembly, and a sense tube. The valve body has an inlet, an outlet, a valve port, and 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. The control assembly is operatively coupled to the control element and includes a diaphragm disposed adjacent a diaphragm chamber. The sense tube has a first end, a second end, and a sense hole. The first end is positioned to communicate with the diaphragm chamber, the second end is disposed adjacent the outlet, and the sense hole being formed in the sense tube between the first end and the second end and being oriented along an axis that is angled relative to an axis of the outlet.

1. A fluid regulating device, comprising:
a valve body having an inlet, an outlet, and a valve port; a control element shiftably disposed within the valve body, the 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, the control assembly including a diaphragm disposed adjacent a diaphragm chamber; and a sense tube having a first end, a second end, and a sense hole, the first end being positioned to provide flow communication with the diaphragm chamber of the control assembly, the second end being disposed adjacent a distal portion of the outlet, and the sense hole being formed in the sense tube between the first end and the second end, the sense hole extending along an axis that is angled relative to an axis of the outlet.
