Float Valve Introduction
A float valve, also known as a ballcock, is a mechanical device used to control the filling and level of fluids in a tank or reservoir. It consists of a hollow, buoyant float connected to a valve mechanism. As the fluid level rises or falls, the float moves up or down, activating the valve to open or close and regulate the flow of fluid.
Key Components and Operation of Float Valves:
Float: The float is typically made of a buoyant material such as plastic or foam. It is designed to float on the surface of the fluid and rise or fall with the fluid level.
Valve Mechanism: The valve mechanism is connected to the float and controls the flow of fluid. When the float rises with the increasing fluid level, it lifts a rod or lever connected to the valve, opening it and allowing fluid to enter the tank. As the fluid level drops, the float descends, closing the valve and stopping the flow of fluid.
Inlet and Outlet Connections: Float valves have inlet and outlet connections that allow fluid to enter and exit the tank or reservoir. The inlet connection is connected to a water supply line, while the outlet connection is linked to the tank or reservoir being filled.
