Here are about the characteristics of V-type regulating
ball valves and when we use it?
The V-type
ball valve is a special type of ball valve with a V-type structure for the ball and seat, which can provide a larger channel area and lower flow resistance.
Characteristics of V-type regulating ball valve
A V-type regulating ball valve is a commonly used regulating valve with the following characteristics:
1. V-type structure
The ball of the V-type regulating ball valve has a V-type notch, which allows the ball valve to achieve precise flow control during opening adjustment. By adjusting the rotation angle of the sphere, the flow rate of the medium can be adjusted to achieve precise adjustment.
2. Good fluid control performance
The V-type regulating ball valve has good regulating performance and control accuracy. Due to the special shape of the ball, the flow path of fluid inside the ball valve will change, thereby changing the flow rate and velocity of the medium. This makes the V-type regulating ball valve exhibit good stability and control accuracy in fluid regulation.
3. Wide application range
V-type regulating ball valves are suitable for various media, including gases, liquids, and suspended particulate matter. They are widely used in fields such as chemical engineering, petroleum, electricity, metallurgy, pharmaceuticals, sewage treatment, etc. They can be used in process control such as flow regulation, pressure regulation, and temperature regulation.
4. Strong wear resistance
V-type regulating ball valves are usually made of wear-resistant and corrosion-resistant materials, such as stainless steel, alloy steel, etc., which have high wear resistance. This allows the V-type regulating ball valve to be used for a long time in a medium with a certain amount of particulate matter without being easily worn.
5. Fast response speed
The V-type regulating ball valve has a simple structure and flexible operation, which can quickly respond to control signals and achieve fast switching and adjustment. This is crucial for the process of controlling frequent changes in flow or rapid response to changes.
6. Reliable sealing performance
The V-type regulating ball valve adopts a metal-to-metal seal. It usually has a good sealing performance. The ball is rotated to fit the valve seat, achieving reliable sealing and reducing the risk of leakage.
In summary, V-type regulating ball valves have the characteristics of precise flow control, good regulating performance, strong wear resistance, fast response speed, and reliable sealing performance. They are commonly used valve types and are widely used in industrial process control.
The usage of the V-type ball valve and the V-type regulating ball valve
V-type ball valves are typically used in the following situations.
1. High viscosity fluid: Due to the special structure of the V-type ball valve, it can effectively reduce fluid compression and friction inside the valve. It is suitable for high viscosity or easily crystallized fluid media, such as paste, honey, asphalt, etc.
2. High temperature and high-pressure media: V-type ball valves have good sealing performance. It can withstand work in high-temperature and high-pressure environments, such as chemical, petroleum, natural gas, and other fields.
3. Need for precise flow control: Due to the higher CV value and lower flow resistance of V-type ball valves, they can provide more precise flow control. They are suitable for fluid control systems that require high precision, such as water treatment, pharmaceuticals, food and other industries.
4. To prevent blockage: The V-type ball valve has a self-cleaning effect between the ball and valve seat, which can prevent the accumulation and blockage of media in the valve. It is suitable for media that are prone to blockage or scaling.
In summary, the special structure and performance of V-type ball valves make them widely used in some special fluid control situations.
