Why do ball valves have balance holes?

Ball valve is a common fluid control valve, widely used in industrial fields. The ball valve with a balance hole is a special design with some unique characteristics and application scenarios.

  1. The structure of ball valve with balance hole

The biggest difference between ball valves with balance holes and ordinary ball valves is the special design of the internal structure. Under normal circumstances, a ball valve with a balance hole is provided with a small hole on the ball, which is connected with the pressure in the pipe and is connected to the outlet side of the ball valve through the pipe. The purpose of this design is to reduce the pressure difference on both sides of the ball when the ball valve is closed, and to prevent the occurrence of difficulties in closing the ball valve due to excessive medium pressure.

  1. Working principle of ball valve with balance hole

When the ball valve with a balance hole is working, when the valve needs to be closed, the pressure of the medium will act on both sides of the ball through the balance hole, playing a balancing role, reducing the pressure difference on both sides of the ball. In this way, even if the medium pressure is very large, it will not produce too much resistance to the operation of the ball valve. At the same time, when opening the valve, the balance hole can help reduce the impact force generated when the medium passes through the valve and extend the service life of the ball valve.

  1. Advantages of ball valve with balance hole

Ball valves with balance holes have the following advantages over ordinary ball valves:

– Prevent the medium pressure is too large to cause the ball valve to close difficult;

– Reduce the impact force when the medium passes through the valve and extend the life of the ball valve;

– Improve the safety and reliability of ball valves.

  1. Application scenarios of ball valves with balance holes

Ball valves with balance holes are suitable for occasions where the medium pressure is large, especially when the medium contains solid particles or is corrosive. For example, in chemical, petroleum, metallurgy and other industries, ball valves with balance holes have been widely used. In addition, because of its flexible operation and simple structure, it is also suitable for general fluid control systems.

  1. Selection and precautions of ball valve with balance hole

When selecting a ball valve with a balance hole, it is necessary to comprehensively consider factors such as medium characteristics, working pressure, and temperature. In addition, pay attention to cleaning the balance hole regularly during installation and maintenance to ensure that it is smooth. In addition, the valve body material and sealing material should be reasonably selected according to the actual working conditions to ensure the stable operation of the ball valve.

Ball valves with balance holes, as a special design of fluid control valves, play an important role in specific working conditions. Through the introduction of this article, I believe that you have a deeper understanding of the ball valve with balance hole, and I hope to help you better choose and use this type of ball valve in practical applications.
