FILL VALVE ACTUATION SYSTEMS AND METHODS

原文（中文）

A fill valve system is disclosed for regulating fluid delivery into a tank or vessel using a combination of mechanical and hydraulic actuation. In some embodiments, the system includes a valve housing with a removable housing cap for internal access, a float arm pivotably coupled to the housing, and/or a float responsive to fluid level changes. In some embodiments, internal actuation components include a pin arm, arm linkage, poppet, diaphragm, and poppet pin. The diaphragm assembly regulates flow through a valve seat via pressure differentials created by a bleed hole mechanism. In some embodiments, a rotatable lock and stem coupling enable angular adjustment of the valve housing relative to an inlet stem, with discrete indexing positions for vertical alignment. In some embodiments, the system further includes a cleaning rotation feature to prevent mineral buildup. Various aspects of the systems and methods described herein are particularly suitable for low-pressure environments.
