Abstract
Description
Technical Field
[0001] This utility model relates to the field of ball valve technology, and in particular to a wear-resistant ball valve for industrial valves. Background Technology
[0002] With the continuous development of materials science, various high-performance wear-resistant materials are constantly emerging. These new materials have the advantages of high hardness, good wear resistance, and strong corrosion resistance, providing a material basis for the research and development of wear-resistant ball valves. By applying these new materials to the ball and sealing components of ball valves, the wear resistance and service life of ball valves can be significantly improved. The continuous development and application of advanced manufacturing processes such as precision casting, powder metallurgy, and laser processing technology have greatly improved the manufacturing precision and quality of ball valves, enabling the manufacture of more precise balls and sealing surfaces, ensuring the sealing performance and wear resistance of ball valves. Laser processing technology can perform high-precision wear-resistant coating treatment on the surface of ball valves, improving surface hardness and wear resistance, while reducing processing errors and improving product consistency and reliability.
[0003] Ball valves achieve sealing through the tight fit between the ball and the seat. During the opening and closing of the valve, friction occurs between the ball and the seat. If the ball's wear resistance is insufficient, wear and scratches will appear on its surface, increasing the sealing gap between the ball and the seat. This reduces the valve's sealing performance and leads to leakage. This not only affects the normal transport of process media but also poses safety hazards. The ball's surface will gradually wear down due to friction during normal use. If the wear resistance is insufficient, the wear rate will accelerate, resulting in pits and scratches on the ball's surface. This prevents the ball and seat from fitting tightly together, reducing sealing performance. As wear intensifies, the medium will leak from the gaps, affecting the valve's shut-off function and reducing the equipment's pressure holding capacity. Poor ball wear resistance also shortens the valve's service life, requiring more frequent repairs or replacements, which increases maintenance costs. Utility Model Content
