气动球阀是由截止阀演变而来
气动球阀是由截止阀演变而来。它具有相同的旋转90度提动作，不同的是旋塞体是球体，有圆形通孔或通道通过其轴线。球面和通道口的比例应该是这样的，即当球旋转90度时，在进、出口处应全部呈现球面，从而截断流动。
Pneumatic ball valve is evolved from stop valve. It has the same 90 degree rotation lifting action, the difference is that the plug body is a sphere, with a circular through-hole or channel through its axis. The ratio between the sphere and the passage port should be such that when the sphere rotates 90 degrees, the sphere should be present at the inlet and outlet, so as to cut off the flow.
