阀门控制

On demand of control dependability and low resistance, so the study focuses on structure of valve.

对阀门的要求，一是控制可靠，二是阻力小，因此其结构是关注的重点。

Double-acting pneumatic actuators: valve opening and closing of the two control.

If the use of flow control valves as the main choice is the right size and type of valve.

如果要求蝶阀作为流量控制使用，主要的是正确选择阀门的尺寸和类型。

Control valves or fluid drive mechanism is driven to rely on pieces of lifting hoist, sliding, rotating or turning motion put to the size of change in flow area to achieve.

阀门的控制功能是依靠驱动机构或流体驱使启闭件升降、滑移、旋摆或回转运动以改变流道面积的大小来实现的。
