Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ball valves, in particular to a tap welding ball valve. Background Art
[0002] The ball valve is an important industrial valve that controls the flow of fluid by rotating a ball in the valve seat. There are one or more channels on the ball, which correspond to the connection ports of the pipeline. When the ball rotates to be parallel to the axis of the pipeline, the fluid can flow freely; when the ball rotates to be perpendicular to the axis of the pipeline, the fluid channel is closed, thereby achieving control of the fluid. The design of the ball valve usually includes components such as the valve body, valve cover, valve stem, ball, seal and actuator. The valve body is the main part of the valve, usually made of cast iron, carbon steel, stainless steel and other materials to adapt to different working media and environmental conditions. The ball is the core component of the ball valve, and its material and surface treatment must ensure good sealing and corrosion resistance. The seal ensures the sealing between the ball and the valve seat to prevent fluid leakage. The valve stem is the component connecting the ball and the actuator, and its design must ensure flexibility and reliability of operation. The actuator can be manual or automatic, such as electric, pneumatic or hydraulic, to adapt to different operating requirements. Ball valves are widely used in many fields such as petroleum, chemical industry, metallurgy, light industry, electric power, shipbuilding, urban water supply and drainage due to their compact structure, small size, light weight, good sealing performance, easy operation, large flow capacity, and rapid opening and closing.
[0003] In the prior art, the valve body of a ball valve is usually produced by punching and milling a metal plate through a CNC center, and then removing excess metal from the metal plate to obtain the valve body of the ball valve. However, punching and milling a metal plate to obtain a valve body takes a long time to complete each valve body, and also causes a certain degree of waste in the metal material during the cutting process. Therefore, other methods are needed to obtain the valve body of a ball valve to save materials and time.
