Float valve is a product of liquid level measurement and control. It is constructed from several main components such as valve body, piston, connecting rod and float, and uses the principle of leverage to make the valve open or block. In the simplest way, it is like a flush toilet at home, and the water supply device used on it has this structure.
The ball valve is a kind of valve, which refers to the valve core (sealing part) of the ball-shaped structure, which is used in the pipeline to block air or water flow. The float level valve is because one end of the switch lever is a hollow sealing ball. Automatically control the opening and closing of the valve through liquid buoyancy.
The float valve floats always float on the water. When the water surface rises, the float also rises. When the water level of the water tank is low, the floating ball decreases with the water level, and the piston in the valve body is pulled out through the connecting rod of the fixed floating ball, which creates a gap between the valve body and the piston, which can make the tap water enter the water tank; when the water level of the water tank reaches the setting point, the float level ball will push the piston in the valve body into the valve body through the connecting rod with the force generated by the rising of the water level. Since the top of the piston is equipped with a sealing rubber gasket, the water outlet in the valve body is processed relatively flat and smooth. When the buoyancy of the float level ball exceeds the pressure of the tap water, the piston with the sealing rubber gasket and the water outlet in the valve body are tightly sealed, and the tap water is closed by the floating ball valve.
