Abstract
A orifice fitting for measuring gas flow in gas pipelines has an energized seal. The orifice fitting has a plate carrier which moves downward into a seat slot to position an orifice plate in the gas flow. An annular seal mounts to the plate carrier for engaging a downstream side of the seat slot. The seal is energized or pressed outwardly by hydraulic fluid pressure. The plate carrier has a chamber containing hydraulic fluid and a piston. A pin protrudes outward. The orifice fitting slide valve carrier engages and pushes the pin downward as the slide valve carrier moves to the closed position.
