Vacuum pressure ball valve，Vacuum ball valve，Ball valve

Youdaoplaceholder0 Vacuum pressure ball valve ‌ is a valve used in vacuum systems, mainly to control the flow of gas in a vacuum environment. The following is a detailed introduction to vacuum pressure ball valves:

Working principle

The working principle of the vacuum pressure ball valve is that the valve stem drives the ball to rotate. Through the sealing fit between the ball and the valve seat, the on-off of the airflow and flow regulation are achieved. When the ball rotates to the position in contact with the valve seat, the valve closes and the airflow cannot pass through. When the ball rotates away from the position of the valve seat, the valve opens and the airflow can pass through. By changing the rotation Angle of the sphere, the opening of the valve can be adjusted to control the flow rate ‌

Structural composition

The vacuum pressure ball valve is mainly composed of the valve body, ball, valve seat, valve stem and operating device, etc. The valve body is usually made of materials such as cast iron or stainless steel to provide support and protection. The sphere is a key component that can rotate within the valve body to control the on-off of the fluid. The valve seat is made of materials such as polytetrafluoroethylene or rubber, which has corrosion resistance and good sealing performance. The valve stem is connected to the ball and the rotation is controlled by manual, electric or pneumatic operating devices. The operating device, including manual, pneumatic and electric types, is used to drive the valve stem to make the ball rotate ‌

Material

The common materials of vacuum pressure ball valves include stainless steel, aluminum alloy and some special alloys. Stainless steel has excellent corrosion resistance and relatively high strength. Aluminum alloy is lightweight and has good processing performance. Special alloys such as Hastelloy and Monel have higher corrosion resistance and strength for extreme working conditions ‌
