Valve Ball

The valve ball is a common valve component, mainly used to control the flow of fluid and has excellent sealing performance. The definition, structure and working principle of the valve ball will be introduced in detail below.

The valve ball is a spherical component located inside the valve that rotates to adjust the flow of fluid. It is usually made of metallic materials such as stainless steel, copper or copper alloy. The outer surface of the ball is smooth and cooperates with the valve seat to ensure the normal operation and sealing performance of the valve.

The structure of the valve ball includes the ball, valve stem and valve seat. Among them, the ball is a key component of the valve, which controls the flow of fluid through rotation. The valve stem is connected to the ball to control and rotate the ball. The valve seat is located under the ball and cooperates with the surface of the ball to ensure the sealing performance of the valve.

The working principle of the valve ball is as follows:

1. Closed state: When the valve is in the closed state, the valve stem rotates to press the ball against the valve seat. A good seal is formed between the ball and the metal surface of the valve seat, preventing fluid leakage.

2. Open state: When the valve needs to be opened, the valve stem rotates to lift the ball from the valve seat. At this time, the fluid can flow through the aperture between the ball and the valve seat to achieve the opening of the fluid.

The valve ball has the following characteristics:

1. Excellent sealing performance: The matching structure of the ball and the valve seat ensures that the valve has high sealing performance and can effectively prevent leakage.

2. Quick switching: The valve ball rotates to achieve rapid fluid switching. For occasions requiring frequent operations, valve balls have higher performance advantages.

3. Wide range of applications: Valve balls are widely used in various industries such as petroleum, chemical industry, metallurgy, and electric power. It is suitable for the control of a variety of liquid, gas and suspended solid particle media.

4. Strong corrosion resistance: The valve ball is often made of corrosion-resistant materials, has good corrosion resistance, and is suitable for various harsh working environments.

The valve ball plays an important role in the industrial field. It controls the on-off of fluid through rotation and has good sealing performance. Its excellent characteristics and wide range of applications make the valve ball a key component in many engineering projects.
