PRESSURE REGULATOR

摘要

A regulator is disclosed that controls fluid flow through a control valve via a linkage including a lever that is acted upon by a spring cylinder acting in a direction perpendicular to the direction of fluid flow through pipes connected to the control valve. The closure performance of the control valve of the regulator is optimized by the direction the spring cylinder acts and the mechanical advantage the lever provides. The regulator further includes a diaphragm and diaphragm cover, and the regulator is configured to allow the diaphragm cover to be stamped rather than cast.
