A brief introduction to the float valve

2022-04-20

The floating valve can float on the tray and change its opening degree with the change of gas flow.

There are many types of float valves, such as round valves and strip angle valves. China mainly uses the circular valve. Among them, the most commonly used is the F1 type, which has been issued by the domestic ministry of standards (JB1118). The standard stipulates that the material of the valve body can be carbon steel, stainless steel or acid-resistant steel; the thickness of the light valve is 1.5mm and the weight is about 25g, and the thickness of the heavy valve is 2mm and the weight is about 33g.

The Float Valve is fixed at the desired height on the vessel wall and connected to the supply line. When the liquid level rises, the float rises and closes the valve through the lever arm. When the liquid level drops, the supply line opens and the medium flows in until the respective liquid level is reached again.
Application areas: industrial water treatment, chemical processing industry
In some practical applications, the strip type float valve is better than the F1 type float valve for the following reasons:
1. The strip type float valve has been widely used, and the similar ones are also the guide float valve, etc.
2. The separation efficiency is relatively high
3. The most practical advantages for users: compared with traditional float valves, it is not easy to fall off and not easily get stuck
4. The processing capacity is more than 20% higher than that of the F1 type float valve
5. The leakage, pressure drop and efficiency of the tray are comparable to those of the F1 type float valve
