What aspects are included in the precision manufacturing of manual ball valve balls

The manual ball valve is an indispensable key component in the industrial fluid control system, and the ball, as one of its core components, plays a vital role in fluid control.

Material selection and quality requirements

Manual ball valve balls are usually made of high-performance metal materials, such as stainless steel (Stainless Steel), Chrome-Moly Steel (Chrome-Moly Steel), etc. These materials offer excellent corrosion resistance, high temperature stability and mechanical strength, making them adaptable to a variety of industrial environments. The manufacturing process requires the use of high-purity raw materials to ensure that the chemical composition of the sphere is uniform and meets the basic requirements of precision manufacturing.

Precision machining technology

The manufacturing process of the sphere requires high-precision processing to ensure the smoothness and accuracy of its surface. CNC machining is usually performed using advanced equipment such as numerically controlled machine tools (CNC) to achieve highly precise spherical shapes and sizes. This precision machining process not only improves the appearance quality of the ball, but also ensures its reliability and stability during valve operation.

Surface treatment and coating

In order to improve the corrosion resistance and surface hardness of the sphere, the sphere usually undergoes a special surface treatment and coating process. Among them, a common treatment method is plating, such as chromium plating, nickel plating, etc., to increase the surface hardness of the sphere and improve wear resistance. In addition, advanced technologies such as ceramic coating can be used to further enhance the corrosion resistance of the sphere and extend its service life.

Sphere geometry and size control

The geometry and size of the ball are one of the determining factors of the sealing performance of the manual ball valve. During the manufacturing process, key parameters such as the diameter, roundness, and spherical surface finish of the sphere need to be strictly controlled. Precision measuring instruments, such as three-dimensional coordinate measuring machines, are used to comprehensively inspect and measure the sphere to ensure that it meets the design requirements. Such precise control not only ensures a close match between the ball and the valve seat, but also improves the sealing and performance stability of the valve.

High-precision ball processing equipment

In order to ensure the precision manufacturing of spheres, manufacturers usually use high-precision sphere processing equipment. Sphere processing equipment is usually equipped with advanced automatic control systems and high-precision cutting tools to achieve precise processing of the sphere surface. Using professional equipment such as CNC ball grinders, the ball manufacturing process can be completed efficiently and accurately.

Temperature control and heat treatment

In the manufacturing process of spheres, temperature control and heat treatment are very important links. Especially for some large or high-precision spheres, heat treatment processes, such as quenching and tempering, are needed to improve their overall strength and hardness. Temperature control can ensure a uniform internal structure of the sphere, reduce residual stress, and improve the mechanical properties of the sphere.

Advanced quality control system

Manual ball valve manufacturers usually establish a complete quality control system to ensure that every manufacturing link of the ball is effectively monitored. Advanced quality inspection equipment, such as X-ray inspection, ultrasonic flaw detection, etc., are used to conduct non-destructive inspection of the sphere to ensure that there are no defects or cracks inside the sphere. This quality control system helps improve the quality controllability of spheres, reduce manufacturing defects, and ensure that products meet high standards.
