What does ball valve mean?
In industrial equipment and daily life, valves are indispensable components, and ball valves have become one of the hot topics due to their unique structure and wide range of applications. This article will introduce in detail the definition, structure, working principle, classification and application scenarios of ball valves, and analyze the latest developments of ball valves in the industry based on the hot topics on the Internet in the past 10 days.
1. Definition of ball valve

A ball valve is a valve that controls fluid on and off or regulates flow by rotating a ball. Its core component is a sphere with a through hole, which can be opened or closed by rotating 90 degrees. Ball valves are widely used in petroleum, chemical industry, water treatment and other fields due to their good sealing, easy operation and high pressure resistance.
2. Structure and working principle of ball valve
The ball valve mainly consists of the following parts:
| Part name | Function description |
|---|---|
| valve body | Accommodates other components and withstands fluid pressure |
| sphere | With through hole, rotation controls fluid on and off |
| valve seat | Sealing ball to prevent fluid leakage |
| Stem | Connect the handle and the ball to transmit rotational force |
| Handle/actuator | Manual or automatic operation of ball rotation |
The working principle of the ball valve is very simple: when the handle is rotated 90 degrees, the through hole of the ball is aligned with the pipe, and the fluid passes through; when the handle is rotated 90 degrees again, the ball closes, blocking the fluid.
3. Classification of ball valves
According to structure and function, ball valves can be divided into the following categories:
| Classification criteria | Type | Features |
|---|---|---|
| Structural form | floating ball valve | The ball floats and is sealed by medium pressure |
| fixed ball valve | Sphere fixed, suitable for high pressure and large diameter | |
| Connection method | Flange ball valve | Flange connection for easy disassembly |
| Threaded ball valve | Threaded connection, suitable for small diameters | |
| Drive mode | Manual ball valve | Handle operation, economical and practical |
| Electric ball valve | Motor drive, automatic control |
4. Application scenarios of ball valves
Ball valves are widely used in the following fields due to their excellent performance:
1.Petrochemical industry: Ball valves are resistant to high pressure and corrosion, and are suitable for oil and gas transportation and chemical processes.
2.water treatment: The ball valve has good sealing performance and can be used in tap water and sewage treatment systems.
3.Electric power industry: Ball valves are used in boilers, cooling water systems, etc.
4.Food and medicine: Sanitary ball valve meets sterility requirements.
5.Building HVAC: Ball valves are used in air conditioning and heating systems.
