what are floating ball valves
The working principle of the float valve is that the float always floats on the water, and when the water rises, the float also rises. When the drift rises, the connecting rod rises. The connecting rod is connected with the valve at the other end. When it rises to a certain position, the connecting rod supports the rubber piston pad and closes the water source. When the water level drops, the float also drops, and the connecting rod drives the piston pad to open. Floating ball valve regulates the amount of liquid supplied by controlling the liquid level. Full-liquid evaporator requires that the liquid level should be kept at a certain height, so it is generally suitable to use floating ball expansion valve. The working principle of float valve is to control the opening or closing of a valve by reducing and raising the float ball in the float chamber under the action of liquid level. The float chamber is placed on one side of the full-liquid evaporator, and the upper and lower balance tubes are connected with the evaporator, so the liquid level of the two evaporators is the same. When the liquid level in evaporator drops, the liquid level in the float chamber also drops, so the float ball drops. The valve openness increases and the liquid supply increases depending on the lever action. Vice versa.
