Working principle of float valve

The float must always float on the water, and when the water rises, the float also rises. When the float rises, it drives the connecting rod to also rise. The connecting rod is connected to the valve at the other end, and when it rises to a certain position, the connecting rod supports a rubber piston pad, sealing the water source. When the water level drops, the float also drops, and the connecting rod drives the piston pad to open.

Float valves regulate the supply of liquid by controlling the liquid level. A full liquid evaporator requires the liquid level to maintain a certain height, and it is generally suitable to use a floating ball expansion valve. The working principle of a float valve is to control the opening or closing of a valve by lowering and raising the float ball in the float chamber due to the action of the liquid level.

The float chamber is placed on one side of the full liquid evaporator, and is connected to the evaporator through a balance tube, so the liquid level height of the two is consistent. When the liquid level in the evaporator drops, the liquid level in the float chamber also drops, causing the float to drop. By relying on the lever, the valve opening increases, increasing the liquid supply. The opposite is also true.
