A new returnable actuator disk of metal seal structure butterfly valve was presented, and its principle, force analysis, characteristic of the actuator were discussed as well.───了一种双向压金属硬密封蝶阀蝶板可逆回转机构，讨论了可逆回转机构的工作原理、受力分析及特点。
The wind can blow up a big piece of white paper, but can't blow away a butterfly, because life force is disobedience.───风可以吹起一大张白纸，却无法吹走一只蝴蝶，因为生命的力量在于不顺从。
This turning force in a butterfly valve is determined by three factors. (1) friction of the disc to seat for sealing (2) Bearing friction (3) Dynamic torque.───蝶阀上的这种旋转作用力取决于三个因素：(1)阀瓣与阀座密封的摩擦力；(2)轴承摩擦力；(3)动力矩。
