Advantages of Float Valve

High Separation Efficiency

Float valves have high separation efficiency due to the design of the float valve plate which allows for good gas-liquid agitation and long contact time, resulting in good mass transfer.

Less susceptible to dislodgement and jamming

Strip float valves are less susceptible to dislodgement or jamming than conventional float valves, which provides a distinct advantage in use.

High capacity

Float valve plates have a large capacity and are capable of handling large quantities of fluids, which is important for applications that require large scale processing.

Lower cost

Float Valve Towers are relatively inexpensive to manufacture, which reduces the overall investment cost of the equipment.

Role of Float Valves

The main function of the float valve is to float on the tower plate and change its opening degree as the gas flow rate changes.

A float valve is a device that floats on the tower plate and is designed to improve the dispersion of the gas phase. Float valves are available in a variety of styles, including circular valves and bar-shaped angle valves, with circular valves being the most commonly used type. Available in carbon steel, stainless steel or acid-resistant steel, the lightweight float valves have a thickness of approximately 1.5mm and a weight of approximately 25g, while the heavy-duty float valves have a thickness of approximately 2mm and a weight of approximately 33g. Float valves are widely used in the industrial water treatment and chemical processing industries, etc. and are designed so that the opening degree can be adjusted automatically in response to changes in the gas flow rate, thus optimizing the dispersion of the gas phase on the tower plate and improving process efficiency and product quality. efficiency and product quality.

Gas phase dispersion configurations on float valve towers also include other types of float valves, such as the F1 float valve, which is fixed to the vessel wall at the desired height and is connected to the supply piping. When the liquid level rises, the float rises and closes the valve by means of a lever arm. When the liquid level falls, the supply line opens and the medium flows in until the respective liquid level is reached again. This design allows the float valve to not only open in response to changes in gas flow, but also to automatically control the rise and fall of the liquid level, thus optimizing fluid control in industrial processes on multiple levels.

How Do Float Valves Work?

Float Valves are widely used because of their excellent overall performance (e.g., high production capacity, high operating flexibility, high plate efficiency, low manufacturing costs, etc.). The working principle of the float plate mainly involves the opening and closing of the float valve, which is realized by the lowering and raising of the float in the float chamber by the action of the liquid level. The float chamber is usually placed on the side of the full-liquid evaporator, and is connected to the evaporator through the upper and lower balance tubes to ensure that the liquid level of both is the same. When the liquid level in the evaporator decreases, the liquid level in the float chamber also decreases, causing the float to fall. This drop relies on leverage to increase the valve opening, thereby increasing the amount of liquid supplied. Conversely, when the liquid level rises, the float rises, reducing the opening of the valve by leverage and decreasing the amount of liquid supplied. This mechanism ensures that the liquid level is stabilized and is the key to the efficient operation of the float valve turret.

Gas from the float valve turret plate rises the valve sheet through the lift holes and is blown horizontally through the annular slit into the liquid layer. Changes in operating gas velocity cause the valve sheet to rise and float, which is part of the working principle of the Float Valve Plate. This design helps to improve the efficiency and performance of the tower, making the Float Valve Tower a promising choice for a wide range of industrial applications.

Function of Float Valve

A float valve is a valve consisting of components such as a crank arm and a float, which can be used to automatically control the liquid level of a water tower or pool. Float valves are characterized by simple maintenance, flexibility and durability, high accuracy of liquid level control, water level is not interfered by water pressure and tight opening and closing without water leakage. Specifically, the working principle of the float valve is based on buoyancy, when the liquid level rises, the float rises with it, and through the connected crank arm pushes the valve to open and make the liquid flow out, thus keeping the liquid level stable. When the liquid level drops, the float drops and the crank arm pushes the valve closed, preventing the liquid from continuing to flow out and keeping the liquid level stable. This design enables the float valve to effectively control the liquid level, avoiding the liquid level from being too high or too low, and ensuring the normal operation of the system.

Float valves are widely used, not only in the water system for controlling the water level, but also widely used in other industries, such as remote-controlled float valves in high water tanks in the automatic filling and stopping the application, as well as submarine ventilator devices in the float valve automatic Open depth design and so on. These applications all reflect the function and advantages of the float valve in the automatic control of liquid level.

Float Valve Installation Direction and Precautions

1. Float valve installation direction
Float valves are generally installed in tanks or water tanks, used to control the level of liquid. The installation direction of the float valve has a great influence on its working effect, usually should be based on the specific circumstances to determine the installation direction.
During installation, it should be ensured that the vent hole of the float valve is facing upwards to ensure that it can suck air normally. Also pay attention to the positional relationship between the float and the inlet pipe, the inlet is generally located below the float, so that when the liquid level drops in the tank, the float can slide smoothly along the inlet pipe.

2. Float valve considerations
① Select the appropriate float valve material
Different liquids will have different requirements for the float valve material, so when selecting the float valve should be based on the nature of the liquid to choose the appropriate material. Such as in the storage and transportation of heavy alcohol and pure water, stainless steel float valve should be selected for installation.
② Float valve maintenance and maintenance
In the process of use, the float valve should always be maintenance and maintenance. Regularly check whether the float ball is broken, whether the float valve is stuck or not, and clean the deposits and dirt in time.
③ Prevent deformation of the float ball
During long-term use, the float is easily deformed by pressure, resulting in inaccurate control of the liquid level. Therefore, avoid deformation of the float during installation and check it regularly for deformation problems.
④ Pay attention to the inclination of the storage tank
When the level of the storage tank is not enough, the float valve will be deviated, which will affect its working effect. Therefore, check whether the tank is level before installation, and adjust it in time if it is tilted.

Types of Float Valves

Ball float valve
Float type float valve is a common type of float valve, which is widely used for its simplicity, durability and easy installation. It consists of a lower permeable pipe, an upper cover block and a float. When the water level drops, the float drops with it, causing the valve to open; conversely, when the water level rises, the float rises and the valve closes. Float type float valve is mainly used in water tanks, pools, water towers, drinking fountains and so on.

Float type float valve
The working principle of the float float valve is similar to that of the ball float valve, but the floating body is a floating plate instead of a floating ball. Float type float valve is usually used in deeper water tanks or water towers, because it can be adjusted according to the height of the water level of the valve opening and closing, to maintain a stable water level. In addition, Float Plate Float Valve can also be used for flow regulation and cut-off and other scenarios.

Floating stem float valve
Floating stem float valve is also a common type of float valve. Unlike ball and plate float valves, the float and the metal rod set on the stem form a single unit. When the water level drops, the float drops with it, causing the valve to open; conversely, when the water level rises, the float rises and the valve closes. Float stem float valve is mainly used in water tanks, pools, water towers, water cooling systems composed of machines and equipment, etc. It is characterized by high temperature resistance, easy to clean, and is suitable for some high temperature scenarios.

Water tank float valve
Water tank float valve is a special type of float valve, common in domestic water tanks, toilet tanks and other scenes. Unlike other types of float valves, water tank float valves are directly embedded inside the water tank to keep the water level in the tank within a reasonable range. When using a water tank float valve, you need to choose the appropriate specification according to different tank sizes and applications.

Hydraulic float valve
Hydraulic float valve is a kind of modern float valve, its working principle is to use hydraulic force to transmit high valve switching force. Hydraulic float valves can be widely used in a variety of hydraulic systems, not only to maintain a higher water level in the system, but also to regulate the water pressure and flow rate, suitable for industrial field use.
