Automatic ball valve is an important fluid control equipment, and its sealing performance is crucial to the stability and safety of fluid control. 
First, material selection is an important factor affecting the sealing effect of automatic ball valve. Different media have different requirements for materials, so the properties of the medium need to be considered when selecting the material of the automatic ball valve. Common materials include stainless steel, copper, cast iron, etc., which have good corrosion resistance. Correct selection of materials can improve the sealing performance of automatic ball valves and avoid leakage and seepage problems. 
Secondly, the design structure is also an important factor affecting the sealing effect of automatic ball valves. The contact area and contact pressure between the ball and the valve seat are key factors that directly affect the sealing effect. The larger the contact area, the more uniform the pressure distribution and the better the sealing effect. In addition, the contact surface between the ball and the valve seat adopts a special design, such as V-shaped seal, elastic seal, etc., which can further improve the sealing effect. 
Third, surface treatment will also affect the sealing performance of the automatic ball valve. The use of advanced surface treatment technologies, such as sandblasting and polishing, can improve the surface smoothness of the ball and the valve seat, reduce friction resistance, and thus improve the sealing effect. In addition, surface treatment can also improve the corrosion resistance of materials and extend the service life of automatic ball valves. 
In addition, correct operation and maintenance also have an important impact on the sealing effect of automatic ball valves. Regular inspection and replacement of seals, keeping the valve body and ball clean, and timely handling of leakage and other problems can all maintain the sealing performance of automatic ball valves. Especially under harsh working conditions such as high temperature and high pressure, choosing suitable materials and sealing structures can ensure the reliable sealing performance of automatic ball valves.
