AI Technical Summary

Technical Problem

The existing ball valve balls are unbearable under high pressure environments, and cannot take into account both structural strength and hollow structure, and cannot effectively block heat of high-temperature fluids and heat exchange of coolant.

Method used

The ball valve ball processing system based on image detection is adopted, and the inner sleeve, middle sleeve and outer sleeve are formed through the FiDU metal inflation process to form a spherical structure and inject molten metal. After cooling, the water leakage is detected to ensure that the ball has a hollow structure and high strength.

Benefits of technology

The high-strength and hollow structure of the ball valve ball is realized, suitable for heat blocking of high-temperature fluids and heat exchange of coolant, improving production efficiency and quality.

Abstract

The present invention discloses a ball valve ball processing system based on image detection and a method for using the same, which belongs to the field of valve ball processing technology and solves the problem that it is difficult to take into account both the structural strength and the hollow structure of the ball valve ball. The method includes the following steps: placing the inner sleeve, middle sleeve, and outer sleeve arranged from the inside to the outside into the spherical cavity of the static mold and the dynamic mold; inflating the outer sleeve with high pressure and expanding the outer sleeve until it conflicts with the inner wall of the spherical cavity; inflating the middle sleeve with high pressure and expanding the middle sleeve until it conflicts with the inner wall of the outer sleeve, and the inflation pressure of the middle sleeve is greater than the inflation pressure of the outer sleeve. The present invention forms the middle sleeve, inner sleeve, and outer sleeve by pre-cutting and spot welding, and then inflates and forms them in sequence to ensure that each component is concentric and the structure is stable. After adding an annular sheet between the middle sleeve and the outer sleeve, molten metal is injected to fill each cavity to form an inner and outer spherical structure. In the subsequent cooling process, thermal imaging detection is used to eliminate leaks and ensure the quality of the finished product.
