<< review queue entry 75281 - submitted by 'encn' >> https://en.m.wikipedia.org/wiki/Ball_valve A ball valve is a flow control device which uses a hollow, perforated, and pivoting ball to control fluid flowing through it. It is open when the hole through the middle of the ball is in line with the flow inlet, and closed when it is pivoted 90 degrees by the valve handle, blocking the flow. 球阀是四分之一圈的形式阀，透过球体来控制流动。手柄平整地对准的流动时打开，并垂直于它在关闭时，使得对所述阀的状态容易视觉确认。 |
