Structural principle of one piece ball valve
Structural Principle
One piece ball valve body is generally made by casting or forging technology, and common materials include carbon steel, stainless steel, and copper. The sphere is a key component of the entire valve, and the surface of the sphere is processed to form a precisely sized valve seat. The valve stem is connected to the ball and the operating handle, and the valve core is opened and closed by the rotation of the operating handle. Seals are generally made of corrosion-resistant materials such as polytetrafluoroethylene (PTFE), which have good sealing performance.
Working Principle
The working principle of a one piece ball valve is relatively simple. When the operating handle rotates, the valve stem drives the ball to rotate, thereby changing the degree of valve opening. In a fully open or closed state, a complete seal is formed between the valve seat of the sphere and the valve body. When the valve is closed, the ball forms a seal by contacting the valve seat, preventing the flow of medium. When the valve is opened, the ball rotates and the medium can flow through the channel between the ball and the valve seat.
