What is the float valve?
The float valve is used to close the liquid flow at a predetermined water level, usually water. Adjust the float valve is working properly, is very accurate and very reliable. In almost every American family, and the float valve can be found in many industrial applications. The concept of the float valve is very simple, it has a reliable and widely used.

How Does a Float Valve Work?
For the reserve tank float valve, has three main parts: valves, dry, and floating devices. Through a pipe, the valve will prevent dry rose, and create a seal water flow. Valve stem connected to a floating device. In some applications, when the stem is also used to adjust the water flow will be blocked. Floating device usually is round and full of air. This equipment is air-tightness, and connected to the stem. Trapped in floating on top of the floating air-buoyancy and water. Reserve a floating device drop, open the valve when the water is released. The float valve will remain open until the float device to improve the water rose to a pre-determined level. Valves, and then will be turned off, turn off the water supply.

Common applications
The float valve is the most common application is the standard household toilets. Located on the back of the toilet float valve inside the tank. Most models have a balloon-shaped floating device connected to the stem extends to the entire tank float valve. When the toilet is refreshed, the float drop, water is released, the valve is activated. Slot, then the cartridge and the valve will be closed. Toilet can be refreshed again.

Ball floating BALL
Another type of float valve is a "ball float valve." In this application, the valve does not close the fluid flow, but seal a vent line. A float valve to maintain the correct positioning a vent line held in place by a bracket. The rise of the water or other liquids, the ball will float up and cover the exhaust pipe. This will prevent any liquid from the vent line to move up. If the seal is working properly, the application can also limit the more liquid into the entrance of the reserve tank.
